Features

Basic Features

Ultra Short Body

The body depth has been greatly reduced. Helps in making thinner control panels.

Easier to Read

For better readability, the character height for the present value

display is 12 mm on models with 4 digits, the largest class in the

industry. The wide viewing angle and brightness provide excellent

visibility. The number of display segments has also been increased to

make settings easier to understand, and the present value display

can be switched between red, green, and orange so that output status

can be seen from a distance.

Note: The display color can be switched on all models except for the

H7CX-A11 and H7CX-R11.

The Easiest Operation

Operation is simplified by the

Up/Down Key for each digit

on 4-digit models and Up

Key for each digit on 6-digit

models.

Safety and Reliability

Isolated Power Supply and Input Circuits

Power supply circuit and input circuits are isolated inside the Counter/

Tachometer. Previous non-isolated counters had wiring restrictions

and could be damaged if wired incorrectly. The H7CX removes these

worries.

Note: Except 12 to 24-VDC models.

Set Value Limit

You can set an upper limit for the set value to prevent unexpected

operation of output devices caused by setting mistakes.

Output Counter

The output counter counts the number of times the output turns ON

(alarms can be displayed and the count can be monitored in

increments of 1,000 operations). This counter is useful in managing

the service life of the Counter/Tachometer or the load.

Refer to Safety Precaut ions on page 52.

For the most recent inf ormation on models that have been certified for

safety standards, refer to yo ur OMRON website.

H7CX-A@-N

Connections

Terminal Arrangement

Confirm that the power supply meets specifications before use.

Transistor Output

• The transistor output of the H7CX is isolated from the internal

circuitry by a photocoupler, so the transistor output can be used as

both NPN and PNP output.

• The diode connected to the collector of the output transistor is used

to absorb inverted voltage that is generated when an inductive load

is connected to the H7CX.

Note: 1. The mounting panel thickness

should be 1 to 5 mm.

To allow easier operation, it is

recommended that Adapters be mounted

so that the gap between sides with hooks

is at least 15 mm (i.e., with the panel

cutouts separated by at least 60 mm).

It is possible to horizontally mount

Timers side by side. Attach the Flush

Mounting Adapters so that the surfaces

without hooks are on the sides of the

Timers. If they are mounted side-by-

side, water-resistance will be lost.

Front Panel (Replacement Part)

You can change the color of the Front Panel when mounting the

Counter/Tachometer. The Counter/Tachometer is shipped with a

black (N1.5) Front Panel. "COUNTER" is printed on the front of

Replacement Front Panels.

Protecting the Counter/Tachometer in Environments

Subject to Oil

The Waterproof Packing will deteriorate, harden, and shrink

depending on the application environment. To ensure maintaining the

IP@6, UL Type 4X waterproof level, periodically replace the

Waterproof Packing. The periodic replacement period will depend on

the application environment. You must confirm the proper

replacement period. Use 1 year or less as a guideline. If the

Waterproof Packing is not replaced periodically, the waterproof level

will not be maintained. It is not necessary to mount the Waterproof

Packing if waterproof construction is not required.

Note: Depending on the operating environment, the condition

of resin products may deteriorate, and may shrink or

become harder. Therefore, it is recommended that resin

products are replaced regularly.

The H7CX's panel surface is water-resistive (conforming to IP@6,

UL Type 4X) and so even if drops of water penetrate the gaps

between the keys, there will be no adverse effect on internal circuits.

If, however, there is a possibility of oil being present on the

operator's hands, use the Soft Cover. The Soft Cover ensures

protection equivalent to IP54F against oil. Do not, however, use the

H7CX in locations where it would come in direct contact with oil.

Counter

Explanation of Functions

Items marked with stars ★ can be set using the DIP switch.

Input Mode (cntm)★

Set increment mode (UP), decrement mode (DOWN), or one of the

increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/

DOWN C) as the input mode.

Input modes other than UP or DOWN modes cannot be set using the

DIP switch and so use the operation keys if other modes are required.

(For details on the operation of the input modes, refer to Input Modes

and Present Value on page page 21.)

Dual Count Calculating Mode ( calm)

When using as a dual counter, select either ADD (addition) or SUB

(subtraction) as the calculation method for the dual count value.

ADD: Dual count value = CP1 PV + CP2 PV

SUB: Dual count value = CP1 PV − CP2 PV

Output Mode (outm)★

Set the way that control output for the present value is output. The

possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H.

Output modes other than N, F, C, or K-1 cannot be set using the DIP

switch and so use the operation keys if other modes are required. The

output modes that can be set vary with the model.

(For details on the operation of the output modes, refer to Input/

Output Mode Settings on page page 22.)

One-shot Output Time (otim)★

Set the one-shot output time (0.01 to 99.99 s) for control output.

One-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is

selected as the output mode. Output times other than 0.5 s or 0.05 s

cannot be set with the DIP switch and so use the operation keys if

other settings are required.

One-shot Output 2 Time (otm2)★

Set the one-shot output time (0.01 to 99.99 s) for control output

(OUT2).

One-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is

selected as the output mode. Output times other than 0.5 s or 0.05 s

cannot be set with the DIP switch and so use the operation keys if

other settings are required.

One-shot Output 1 Time (otm1)

Set the one-shot output time (0.01 to 99.99 s) for control output

(OUT1).

One-shot output can be used only when D, L, or H is selected as the

output mode.

If the output time is set to 0.00, hold is displayed, and outputs are

held.

Counting Speed (cnts)★

Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2

inputs together.

If contacts are used for input signals, set the counting speed to 30 Hz.

Processing to eliminate chattering is performed for this setting.

Reset Input Signal Width (iflt)★

Set the reset input signal width (20 ms/1 ms) for reset/reset 1 and total

reset/reset 2 inputs together.

If contacts are used for the input signal, set the input signal width to

20 ms. Processing to eliminate chattering is performed for this setting.

Decimal Point Position (dp)

Decide the decimal point position for the present value, CP1/CP2

present values, set value (SV1, SV2), total count value, and dual

count set value.

Prescale Value (pscl)

Pulses input to the counter are converted according to the specified

prescale value.

(Setting range: 0.001 to 99.999 for 6-digit models and 0.001 to 9.999

for 4-digit models.)

Example: To display the feed distance for systems that output 25

pulses for a feed length of 0.5 m in the form @@.@@ m:

1. Set the decimal point position to 2 decimal places.

2. Set the prescale value to 0.02 (0.5 ÷ 25).

• Observe the following points when setting a prescale value.

Set the set value to a value less than {Maximum countable value

− Prescale val ue}.

Example: If the prescale value is 1.25 and the counting range is

0.000 to 999.999, set the set value to a value less than 998.749

(= 999.999 − 1.25).

If the set value is set to a value greater than this, output will not turn

ON.

• Output will turn ON, however, if a present value overflow occurs

(FFFFFF or FFFF).

NPN/PNP Input Mode (imod)

Select either NPN input (no-voltage input) or PNP input (voltage

input) as the input format. When using a two-wire sensor, select NPN

input.

The same setting is used for all external inputs.

For details on input connections, refer to Input Connections on page

page 9.

Display Color (colr) (Displayed fo r terminal block models

(except H7CX-A11@) only.)

Set the color used for the present value.

* Output 2 for 2-stage models.

With the twin counter, output 1 and output 2 will both turn OFF when

the output status is OFF. Either output 1 or output 2 will turn ON when

the output status is ON.

Counter

Absolute Value Setting/Forecast Value Setting (setm)

For the 2 count output mode, an absolute value setting (abs) or

forecast value setting (ofst) can be set for set value 1.

When a forecast value is set, specify the forecast value set value (i.e.,

the deviation for the set value).

The forecast output (output 1) turns ON when the present value

reaches the forecast value.

If the forecast set value is greater than or equal to the set value, the

forecast output (output 1) will turn ON as soon as counting starts.

If the forecast value setting is used, specify the set value 2 minus the

forecast value setting for set value 1.

Set Value Upper Limit (sl-h)

Set the upper limit for the set value when it is set in run mode.

The setting can be made from 1 to 9999 for 4-digit models and from

1 to 999999 for 6-digit models.

Forecast Set Upper Limit (pl-h)

Set the upper limit for the forecast set value.

The setting can be made from 1 to 9999 for 4-digit models and from

1 to 999999 for 6-digit models.

Batch Coun t Upper Limit (bl-h)

Set the upper limit for the batch count value. The setting can be made

from 1 to 9999 for 4-digit models and from 1 to 999999 for 6-digit

models.

Output Allocation (otst)

When using an H7CX-AU@-N model as a 2-stage counter, the output

can be flexibly allocated to either stage 1 or 2.

The transistor output can be allocated to SV1 and the contact output

to SV2 or vice verse, as in the following tables.

Counter

Total and Preset Counter Operation

The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value.

Batch Counter Operation

The H7CX has a batch counter, separate from the 1-stage preset counter, for counting the number of times the count has been completed.

Note: 1. The batch count value is held at 0 during batch counter reset input.

2. If the batch count set value is 0, batch count will be perf ormed but there will be no batch output.

3. The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digi t models).

4. Once batch input has been turned ON, it will ret urn to the ON state after power interruptions.

5. If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON.

6. After batch output t urns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count value.

Dual Counter Operation

Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for

which output turns ON when the set value matches the added or subtracted result.

Note: 1. Counting is not possible for CP1 during reset 1 input. CP2 will not be affected. The dual count va lue will be calculated based on a CP1 present value of 0.

2. Counting is not possible for CP2 during reset 2 input . CP1 will not be affected. The dual count value will be calculated based on a CP2 present value of 0.

3. The counting range for the dual count value is −99,999 to 999,999 (0 to 9,999 for 4-digit models).

The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999 (0 to 9,999 for 4-digit models).

If a present value exceeds 999,999 (9,999 for 4-digit models), FFFFFF (FFFF for 4-digit models) will be displayed to indicate an overflow, and all counting

will stop.

• The total counter continues to count the total

accumulated value when the present value is

reset using reset/reset 1 input (Reset Key).

• The total count value is reset when the total

reset/reset 2 input is turned ON.

If the Reset Key is pressed while the total count

value is displayed, the total count value is reset.

The present value is also reset at this time.

• The counting range of the total counter is

−99,999 to 999,999 (−999 to 9,999). The total

count value returns to 0 when it reaches the full

scale limit.

• The batch counter continues after count

completion.

• Batch output is held until batch counter reset is

input.

• When the batch counter reset input is turned

ON, the batch count value is reset, and batch

output turns OFF.

• If the Reset Key is pressed while the batch

count value is displayed, the batch count value

is reset and batch output turns OFF. The

present value is also reset at this time.

• The count value can be incremented and

decremented.

The batch count is only incremented.

• The maximum counting speed for batch counter

operation is 5 kHz. The batch counter counts

the number of times the count reaches the set

value.

• The operation after count completion for the

dual counter value is determined by the output

mode.

Tachometer

Explanation of Functions

Tachometer Operation

Items marked with stars ★ can be set using the DIP

switch.

Tachometer Input Mode (tinm)

Set the count input mode to one of the following: 1 input (F1), 2 inputs

(F2), error (F3), absolute ratio (F4), or error ratio (F5).

Tachometer Output Mode (totm)★

Set the output m etho d f or contro l outp ut b ased o n th e comp ariso n

valu e. Upper and lower limit (HI-LO), area (AREA), upper limit (HI-HI),

and lower limit (LO-LO) can be set.

(For details on the output modes, refer to Output Mode Settings and

Operation on page page 34.)

Counting Speed (cnts)★

Set the maximum counting speed (30 Hz/10 kHz) for CP1 input.

If contacts are used for input signals, set the counting speed to 30 Hz.

Processing to eliminate chattering is performed for this setting.

Decimal Point Position (dp)

Decide the decimal point position for the measurement value, OUT1

set value, and OUT2 set value.

Prescale Value (pscl)

It is possible to display the rate of rotation or the speed of a device or

machine to which the H7CX is mounted by converting input pulses to

a desired unit.

If this prescaling function is not used, the input frequency (Hz) will be

displayed.

It is also possible to specify time (seconds) as the display value. Refer

to Display Unit on page page 31 for details.

The relationship between display and input is determined by the

following equation. Set the prescale value according to the unit to be

displayed.

Displayed value = f × α

f: Input pulse frequency (number of pulses in 1 second)

α: Prescale value

(1) Displaying Rotation Rate

N: Number of pulses per revolution

Example: To display the rate of rotation for a machine that outputs 5

pulses per revolution in the form @@.@ rpm:

1. Set the deci ma l poi nt po si tion to 1 decimal plac es .

2. Using the formu la, set the prescale value (α) to 1/ N × 60 = 60/5 = 12.

(2) Displaying Speed

N: Number of pulses per revolution

d: Diameter of rotating body (m)

πd: Circumference (m)

• Observe the following points when

setting a prescale value.

Set the set value to a value less than {Maximum countable value −

Prescale value}.

Example: If the prescale value is 1.25 and the counting range is

0.000 to 999.999, set the set value to a value less than 998.749 (=

999.999 − 1.25).

If the set value is set to a value greater than this, output will not turn

ON.

* Output will turn ON, however, if a presen t value overflow occurs (FFFFFF or FFFF}.

Averaging Method (avgt) (Only for Tachometer Operation)

A simple average or moving average can be selected for the

averaging. With the moving average method, the average of the

measurement values is displayed each sampling cycle, in contrast to

a simple average, with which the the average of the set number of

samples is displayed.

Number of Averaging Times (avgn)★

Flickering display and output chattering can be prevented using

average processing. Average processing can be set to one of four

levels: no average processing, 2 times (i.e., the average of 2

measurement values), 4 times, 8 times, or 16 times.

The measurement cycle will be equal to the sampling cycle multiplied

by the average processing setting (i.e., the number of times).

Average processing enables stable displays even for fluctuating input

signals. Set the optimum number of times for the application.

Auto-zero Time (auto0)

The display can be force-set to 0 if there is no pulse for a certain

period of time. This time is called the auto-zero time. Set the auto-zero

time to a time slightly longer than the estimated interval between input

pulses. Accurate measurement is not possible if the auto-zero time is

set to a time shorter than the input pulse cycle. Setting a time that is

too long may also result in problems, such as a time-lag between

rotation stopping and the alarm turning ON. The auto-zero time is not

applied to pulse width measurements.

Startup Time (stmr)

To prevent undesired outputs resulting from unstable inputs

immediately after the power supply is turned ON, it is possible to

prohibit measurement for a set period of time, the startup time.

It can also be used to stop measurements and disable outputs until

the rotating body reaches the normal rate of rotation, after the power

supply to the H7CX and rotating body are turned ON at the same time.

Peak/bottom Hold Enabled (dhld)

This function records the peak and bottom (i.e., minimum) after

counting starts (after turning ON the power supply or changing the

configuration selection mode or function setting). The peak value is

also held when the power supply is interrupted.

Output Hysteresis (hys)

This setting can be used to prevent output chattering if the

measurement value fluctuates slightly near the set value.

The measurement value after prescaling is set.

Output OFF Delay (offd)

This function delays the timing for turning OFF comparative output by

a certain time.

The ON time can be held for the set time if the comparative result

changes in a short time.

Operation will continue and outputs will not change when holding the

value.

Set Value Upper Limit (pl-h)

Set the upper limit for the set value when it is set in run mode. The

limit can be set to between 1 and 999999.

Output Allocation (otst)

When using an H7CX-AU@-N model as 2-stage counter, each output

can be flexibly allocated to either stage 1 or 2.

The transistor output can be allocated to SV1 and the contact output

to SV2 or vice verse, as in the following tables.

width measurement.

With pulse cycle measurement, the number of pulse cycles that occur

in 1 s is measured.

With pulse width measurement, the ON time for one pulse is

measured.

An input OFF period of at least 20 ms is required for pulse width

measurement.

If there is no input pulse during pulse width measurement, the

previously measured value will be held.

Key Protect Level

It is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the key protect level (KP-1 to KP-7) when the

key-protect switch is set to ON.

The key protect level is set in the function setting mode. The key protect indicator is lit when the key-protect switch is ON.

Self-diagnostic Function

The following displays will appear if an error occurs.

*1. Displays for 4-digit models are given in parentheses.

*2. This includes times when the life of the EEPROM has expired.

*3. This occurs if the present value or total count value falls below −99999

(−999 for 4-digit models).

*4. This occurs in the following conditions if the present value (i.e.,

measurement value) exceeds 999999 (999 9 for 4-digit models).

• For Output Modes K-2, D, L, or H

• Dual counter or tachometer operation is used.

*5. Display flashes.(1-second cycles)

*6. This does not apply when tachom eter operation is used.

*7. This is displayed if t he alarm value setting for either of the two outputs is

exceeded if a model with two outputs is used .The total ON count will not be

cleared by using the Reset Key.

*8. The normal display and e3 will appear alternately.

When the Reset Key is pressed, e3 will not be displayed even if the alarm

set value is exceeded.

(Monitoring is possible, however , because the counter will continue without

the output ON count being cleared.)

The Waterproof Packing can be used to achieve protection equivalent

to IP66.

(The Waterproof Packing will deteriorate, harden, and shrink

depending on the application environment. To ensure maintaining the

NEMA4 waterproof level, periodically replace the Waterproof

Packing. The periodic replacement period will depend on the

application environment. You must confirm the proper replacement

period. Use 1 year or less as a guideline. If the Waterproof Packing is

not replaced periodically, the waterproof level will not be maintained.)

It is not necessary to mount the Waterproof Packing if waterproof

construction is not required.

Connection Sockets

Refer to Connection Sockets on page page 13 for details.

Optional Products for Track Mounting

Refer to Optional Products for Track Mounting on page page 14 for details.

The H7CX's panel surface is water-resistive (conforming to IP@6,

UL Type 4X) and so even if drops of water penetrate the gaps

between the keys, there will be no adverse effect on internal circuits.

If, however, there is a possibility of oil being present on the

operator's hands, use the Soft Cover. The Soft Cover ensures

protection equivalent to IP54 against oil. Do not, however, use the

H7CX in locations where it would come in direct contact with oil.

Note: Depending on the operating environment, the condition

of resin or rubber products may deteriorate, or they may

shrink or become harder. Therefore, it is recommended

that resin products be replaced regularly.

H7CX-R@-N

Explanation of Functions

Basic Functions

Input Mode

The mode can be switched between tachometer mode and AMD-

compatible mode.

Tachometer Mode

Use this mode to measure the pulse frequency (Hz).

AMD-compatible Mode

Use this mode to measure the pulse cycle (s).

Counting Speed

Set the maximum counting speed (30 Hz/10 kHz) for input. If contacts

are used for input signals, set the counting speed to 30 Hz.

Processing to eliminate chattering is performed for this setting.

Output Mode

Set the output method for control output based on the comparison

value.

Upper and lower limit (HI-LO), area (AREA), upper limit (HI), and

lower limit (LO) can be set. For the H7CX-RW@, the upper limit (HI-

HI) and lower limit (LO-LO) can be set. (For details on the operation

of the output modes, refer to Output Mode Settings on page page 49.)

Averaging Method (avgt)

Simple averaging (SMP) or a moving average (MV) can be selected

for the averaging method.

With a moving average, the average measurement value is displayed

every sampling cycle or pulse cycle, in contrast to simple averaging,

for which the average value is displayed for the set number of

samples.

Number of Averagin g Times

Flickering display and output chattering can be prevented using

average processing. Average processing can be set to one of four

levels: no average processing, 2 times (i.e., the average of 2

measurement values), 4 times, or 8 times.

For a measurement frequency of 5 Hz or higher using a tachometer,

the average will be equal to the sampling cycle (200 ms) multiplied by

the averaging setting (i.e., the number of times).

For less than 5 Hz, the frequency will be measured when the input

pulse comes. Average processing produces a stable display even for

fluctuating input signals. Set the optimum number of times for the

application.

If AMD-compatible mode is used, the measurement cycle will be

measured when the input pulse is received. The output will change,

however, when the comparison value is exceeded even if averaging

is enabled.

NPN/PNP Input Mode

Select either NPN input (no-voltage input) or PNP input (voltage

input) as the input format. When using a two-wire sensor, select NPN

input.

The same setting is used for all external inputs.

For details on input connections, refer to Input Connections on page

page 40.

Advanced Functions

Decimal Point Position (dp)

Decide the decimal point position for the measurement value and

comparison value.

Prescale Value (pscl)

It is possible to display the rate of rotation or the speed of a device or

machine to which the H7CX is mounted by converting input pulses to

a desired unit.

If the default prescaling value (1,000) is used, the input frequency

(Hz) will be displayed.

The relationship between display and input is determined by the

following equation. Set the prescale value according to the unit to be

displayed.

Displayed value = f × α

f: Input pulse frequency (number of pulses in 1 second)

α: Prescale value

(1) Displaying Rotation Rate

N: Number of pulses per revolution

Example: In order to display the rate of rotation for a machine that

outputs 5 pulses per revolution in the form @@.@ rpm:

1. Set the decimal point position to 1 decimal places.

2. Using the formula, set the prescale value (α) to

1/N × 60 = 60/5 = 12.

(2) Displaying Speed

N: Number of pulses per revolution

d: Diameter of rotating body (m)

πd: Circumference (m)

• Observe the following points when

setting a prescale value.

Set the set value to a value less than {Maximum countable value

− Prescale value}.

Example: If the prescale value is 1.25 and the counting range is

0.000 to 999.999, set the set value to a value less than 998.749

(= 999.999 − 1.25).

If the set value is set to a value greater than this, output will not turn

ON.

Auto-zero Time (auto0)

It is possible to make the settings so that the frequency will be force-

set to 0 if there is no pulse for a specified period of time. This time is

called the auto-zero time.

d: Diameter

body (m)

Note: If the prescale value setting is incorrect, a counting error will

occur. Check that the settings are correct before using this

function.

Note: Set the auto-zero time to a time slightly longer than the

estimated interval between input pulses. It will not be

possible to make accurate measurements if the auto-zero

time is set to a time shorter than the input pulse cycle.

Setting a time that is too long may also result in problems,

such as a time-lag between rotation stopping and the

alarm turning ON.

H7CX-R@-N

Startup Time (stmr)

In order to prevent undesired output resulting from unstable input

immediately after the power supply is turned ON, measurement can

be prohibited for a set time at startup.

It can also be used to stop measurement and disable output until the

rotating body reaches the normal rate of rotation, after the power

supply to the H7CX and rotating body are turned ON at the same time.

Peak/bottom Hold Enabled (dhld)

This function records the peak and bottom (i.e., minimum) values

after counting starts (after turning ON the power supply or changing

the configuration selection mode or function setting).

The peak value is also held when the power supply is interrupted.

Output Hysteresis (hys)

This setting can be used to prevent output chattering if the

measurement value fluctuates slightly near the set value.

In Thachometer Mode, the measurement value after prescaling is set.

Output OFF Delay (offd)

This function delays the timing for turning OFF comparative output by

a certain time.

The ON time can be held for the set time if the comparative result

changes in a short time.

Operation will continue and outputs will not change while holding the

value.

Set Value Upper Limit (sl-h)

Set the upper limit for the set value when it is set in run mode.

Key Protect Level (ypt)

Set the key protect level.

Refer to Key Protect Level on page page 48.

Output ON Count Alarm Set Value (on-a)

Set the alarm value for the output ON count.

The limit can be set to between 0 × 1000 (0 times) and 9999 × 1000

(9,999,000 times). Only the underlined values are set. The alarm will

be disabled if 0 is set.

If the total ON count of the output exceeds the alarm set value, e3

will be displayed on the Timer to indicate that the output ON count

alarm value was exceeded. Refer to Self-diagnostic Function on page

page 48 for information on the e3 display.

ON Count Alarm Set Values for Outputs 1 and 2 (OUT1

and OUT2) (on1a and on2a)

Set the ON count alarm values for the outputs 1 and 2.

The limit can be set to between 0 × 1000 (0 times) and 9999 × 1000

(9,999,000 times). Only the underlined values are set. The alarm will

be disabled if 0 is set.

If the total ON count of instantaneous output 1 or 2 exceeds the alarm

set value, e3 will be displayed on the Timer to indicate that the output

ON count alarm value was exceeded. Refer to Self-diagnostic

Function on page page 48 for information on the e3 display.

Output ON Count Monitor Value (on-c)

The monitor value is only displayed. It cannot be set.

The output ON count will be 1,000 times the displayed value.

ON Count Monitor Values for Outputs 1 and 2 (OUT1 and

OUT2) (on1c and on2c)

The monitor value for output 1 or 2 is only displayed. It cannot be set.

The output ON count will be 1,000 times the displayed value.

Key Protect Level

When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the

key protect level (KP-1 to KP-7). The key protect level is set in the function setting mode. The key protect indicator is lit when the key-protect switch

is ON.

* Changing mode to DIP switch monitor mode or function setting mode.

Self-diagnostic Function

The following displays will appear if an error occurs.

*1. This includes times when the life of the EEPROM has expired.

*2. Occurs when the measurement value reaches 999,999.

*3. Display flashes (1-second cycles).

*4. The normal display and e3 will appear alternately.

When the Hold Key is pressed, e3 will not be displayed even if the alarm set value is exceeded. (Monit oring is possible, however, because the count er will continue

without clearing the output ON count.)

Precautions for the H7CX-R

In upper and lower limit output mode, if the comparison value setting is such that comparison value 1 ≥ comparison value 2, the output will always

be ON.

Hold Function

The measurement value (display value) and output are sustained while the hold input is ON.

Note: The output will maintain the current status when the hold key is pressed.

Example:

* The H7CX-R11W@-N does not have a hold input.

Operation in DIP Switch Monitor Mode

The H7CX-R is also equipped with a DIP switch monitor function, a convenient function that enables the settings of the DIP switch pins to be

confirmed using the front display.

Safety Precautions for All H7CX Series (Common)

Do not allow pieces of metal, wire clippings, or fine

metallic shavings or fillings from installation to enter

the product. Doing so may occasionally result in

electric shock, fire, or malfunction.

Minor injury due to explosion may occasionally occur.

Do not use the Counter where subject to flammable or

explosive gas.

Fire may occasionally occur. Tighten the terminal

screws to the rated torque.

H7CX terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 N·m)

P2CF Socket terminals: 4.4 lb-in (0.5 N·m)

Minor injury due to electric shock may occasionally

occur. Do not touch any of the terminals while power

is being supplied. Be sure to mount the terminal cover

after wiring.

The life expectancy of the output relay varies

considerably according to its usage. Use the output

relay within its rated load and electrical life

expectancy. If the output relay is used beyond its life

expectancy, its contacts may become fused or there may be a

risk of fire. Also, be sure that the load current does not exceed

the rated load current and when using a heater, be sure to use a

thermal switch in the load circuit.

Minor electric shock, fire, or malfunction may

occasionally occur. Do not disassemble, modify, or

repair the Counter or touch internal components.

• The panel surface of the H7CX-A/-R is water-resistant (conforming

to NEMA4, IP66, UL Type 4X (Indoor Use Only). To protect the

internal circuits from water penetration through the space between

the H7CX and operating panel, waterproof packing is included.

Attach the Y92F-30 Adapter with sufficient pressure with the

reinforcing screws so that water does not penetrate the panel.

• When mounting the Counter to a panel, tighten the two mounting

screws alternately, a little at a time, so as to keep them at an equal

tightness. If the panel screws are tightened unequally, water may

enter the panel.

• Store the Counter at the specified temperature. If the Counter has

been stored at a temperature of less than

−10°C, allow the Counter to stand at room temperature for at least

3 hours before use.

• Mounting the Counter side-by-side may reduce the life

expectancies of internal components.

• Use the Counter within the specified ranges for the ambient

operating temperature and humidity.

• Do not use in the following locations:

• Locations subject to sudden or extreme changes in temperature.

• Locations where high humidity may result in condensation.

• Do not use the Counter outside of the rated ranges for vibration,

shock, water exposure, and oil exposure.

• Do not use this Counter in dusty environments, in locations where

corrosive gasses are present, or in locations subject to direct

sunlight.

• Install the Counter well away from any sources of static electricity,

such as pipes transporting molding materials, powders, or liquids.

• Internal elements may be destroyed if a voltage outside the rated

voltage range is applied.

• Be sure that polarity is correct when wiring the terminals.

• Separate the Counter from sources of noise, such as devices with

input signals from power lines carrying noise, and wiring for I/O

signals.

• Do not connect more than two crimp terminals to the same

terminal.

• Up to two wires of the same size and type can be inserted into a

single terminals.

• Use the specified wires for wiring. Applicable Wires: AWG 18 to

AWG 22, solid or twisted, copper

• Install a switch or circuit breaker that allows the operator to

immediately turn OFF the power, and label it to clearly indicate its

function.

• When the Counter is operated with no-voltage input (NPN input),

approximately 14 V is output from the input terminals. Use a sensor

that contains a diode.

• Use a switch, relay, or other contact so that the rated power supply

voltage will be reached within 0.1 seconds. If the power supply

voltage is not reached quickly enough, the Counter may

malfunction or outputs may be unstable.

• Use a switch, relay, or other contact to turn the power supply OFF

instantaneously. Outputs may malfunction and memory errors may

occur if the power supply voltage is decreased gradually.

• When changing the set value during operation, because the H7CX

uses a constant read-in system, output will turn ON if the set value

is equal to the present value.

• When changing the comparison value during operation, because

the H7CX uses a constant read-in system, the output status will

change if the comparison value is changed to a value on the other

side of the present value. (when using as a tachometer)

• If the set value and present value are both 0, the output will turn

ON for the default setting. The output will turn OFF during a reset

operation. (when using as a counter)

• When the power is turned ON using the factory settings, the output

will turn ON after 999.9 s if no pulses are received as count input.

• Do not use organic solvents (such as paint thinners or benzine),

strong alkali, or strong acids. They will damage the external finish.

• Confirm that indications are working normally, including the

backlight LED, and LCD. The indicator LEDs, LCD, and resin parts

may deteriorate more quickly depending on the application

environment, preventing normal indications. Periodic inspection

and replacement are required.

• The waterproof packing may deteriorate, shrink, or harden

depending on the application environment. Periodic inspection and

replacement are required.

CAUTION

Precautions for Safe Use

Input0 V

Sensor

Diode

H7CX-@-N

• H7CX models with a 12 to 24-VDC power supply use a

transformer-free power supply method in which the power supply

terminals are not isolated from the signal input terminals. If a non-

isolating DC power supply is used, unwanted current paths may

occasionally burn or destroy internal components depending on

the wiring. Always check the wiring sufficiently before use.

• An inrush current of approx. 10 A will flow for a short time when the

power supply is turned ON. If the capacity of the power supply is

not sufficient, the Counter may not start. Be sure to use a power

supply with sufficient capacity.

• Maintain voltage fluctuations in the power supply within the

specified operating voltage range.

• When turning the power ON and OFF, input signal reception is

possible, unstable, or impossible as shown in the diagram below.

• Inrush current generated by turning ON or OFF the power supply

may deteriorate contacts on the power supply circuit. Turn ON or

OFF to a device with the rated current of more than 10 A.

• The capacity of the external power supply is 100 mA at 12 V. When

using a 24 VAC/12 to 24 VDC power supply, reduce the load with

the power supply voltage, as shown in the following diagram (DC

power supplies only).

• If the prescale value setting is incorrect, a counting error will occur.

Check that the settings are correct before using this function.

• Make sure that all settings are appropriate for the application.

Unexpected operation resulting in property damage or accidents

may occur if the settings are not appropriate.

• Do not leave the Counter for long periods at a high temperature

with output current in the ON state. Doing so may result in the

premature deterioration of internal components (e.g., electrolytic

capacitors).

• EEPROM is used as backup memory when the power is

interrupted. The write life of the EEPROM is 100,000 writes. The

EEPROM is written at the following times:

• When the power supply is turned OFF

• When switching from Configuration Selection Mode or Function

Setting Mode to Run Mode

• Dispose of the product according to local ordinances as they apply.

• Attach the front panel when using the Counter. The tabs in the

middle of each of four sides secure the front panel to the main

body. To remove the panel, widen the four tabs and pull the panel

toward you.

To mount the panel, fit all four tabs correctly into the grooves on the

main body.

• When conforming to EMC standards, refer to the information

provided in this datasheet for cable selection and other conditions.

• This is a class A product. In residential areas it may cause radio

interference, in which case the user may be required to take

adequate measures to reduce interference.

•H7CX-A@-N: Basic insulation is provided between power supply

and input terminals, between power supply and output terminals,

and between input and output terminals. (However, no insulation is

provided between the power supply and input terminals for the

H7CX-A@D-N.)

•H7CX-R@-N: Basic insulation is provided between power supply

and input terminals and between input and output terminals.

• When double insulation or reinforced insulation is required, apply

double insulation or reinforced insulation as defined in IEC 60664

that is suitable for the maximum operating voltage with clearances

or solid insulation.

• Connect the input and output terminals to devices that do not have

any exposed charged parts.
