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. 2. The H7CX's panel surface is water-resistive (conforming to IP66) 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. Soft Cover Y92A-48F1 Flush Mounting Adapter (provided with screw-terminal models) Waterproof Packing (provided with screw-terminal models) Y92F-30 Y92S-29 When using the Y92S-29, the degree of protection for the H7CX's panel surface conforms to NEMA4, UL Type 4X, and IP66.

Prescale Value (pscl) 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 23.) 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. Dual Count Calculating Mode (calm) 2. Set the prescale value to 0.02 (0.5/25). When using as a dual counter, select either ADD (addition) or SUB (subtraction) as the calculation method for the dual count value. SUB mode can be used only when K-2, D, L, or H is selected as the output mode with 6-digit models. ADD: Dual count value = CP1 PV + CP2 PV SUB: Dual count value = CP1 PV - CP2 PV 0.5 m Output Mode (outm) (Setting possible using DIP switch.) 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 24.) One-shot Output Time (otim) (Setting possible using DIP switch.) 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) (Setting possible using DIP switch.) When using as a 2-stage counter or batch counter, 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) When using as a 2-stage counter, 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. HOLD cannot be set when the output mode is K-2. 25 pulses Encoder NPN/PNP Input Mode (imod) Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. The same setting is used for all external inputs. For details on input connections, refer to Input Connections on page 11. Display Color (colr) Set the color used for the present value. Output OFF (See note.) Output ON (See note.) red Red (fixed) grn Green (fixed) r-g Red Green g-r Green Red Note: When using as a 2-stage counter, this is the status of output 2. Output Allocation (otst) When using H7CX-AU@ models as a 2-stage counter, the output can be flexibly allocated to either stage 1 or 2. Transistor output can be allocated to SV1 and contact output for SV2 or vice verse, as in the following table. H7CX-AU/-AUD1 OUT1 OUT2 Counting Speed (cnts) (Setting possible using DIP switch.) off Transistor (12-13) Contact (3, 4, 5) on Contact (3, 4, 5) Transistor (12-13) 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. H7CX-AUSD1 Reset Input Signal Width (iflt) (Setting possible using DIP switch.) OUT1 OUT2 off Transistor (12-13) Transistor with diode (3, 4, 5) on Transistor with diode (3, 4, 5) Transistor (12-13) 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 input signals, set the counting speed 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. 20 H7CX-A Key Protect Level (kypt) Set the 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-5). The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/OFF status of the keyprotect switch after the H7CX is mounted to the panel. (See note) OFF ON Note: Factory-set to OFF Key protect indicator Level Meaning Details Changing mode (See note.)

The outputs are ON while the count is equal. -99999 OUT1 OUT2 L Reset/ reset 1 999999 Set value 2 Set value 1 0 -99999 The display continues to increase/decrease until the overflow or underflow value is reached. OUT1 is held while the present value is less than or equal to set value 1. OUT2 is held while the present value is greater than or equal to set value 2. OUT1 OUT2 H Reset/ reset 1 999999 Set value 2 Set value 1 0 -99999 OUT1 OUT2 The display continues to increase/decrease until the overflow or underflow value is reached. OUT1 is held while the present value is greater than or equal to set value 1. OUT2 is held while the present value is greater than or equal to set value 2. Note: H mode is available only when using a 6-digit model as a 2stage counter. Note: 1. Counting cannot be performed during reset/reset 1 input. 2. If reset/reset 1 is input while one-shot output is ON, one-shot output turns OFF. 3. If there is power failure while output is ON, output will turn ON again when the power supply has recovered. For one-shot output, output will turn ON again for the duration of the output time setting once the power supply has recovered. 4. Do not use the counter function in applications where the count may be completed (again) while one-shot output is ON. 26 H7CX-A Total and Preset Counter Operation The H7CX has a total counter, separate from the 1-stage preset counter, for counting the total accumulated value. Reset/reset 1 Total reset/reset 2 Present value 0 999999 Total count value 0 Note: The full scale (FS) for H7CX 4-digit models is 9999. * 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. 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. Reset 1 Reset 2 (batch counter reset) Set value Present value 0 OUT2 Batch count set value (Sub-display) Batch count value (Main display) 2 * 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. * Although the count value can be incremented and decremented, the batch count is only incremented. 1 0 OUT1 (batch output) Note: The above is for when the output mode is C. Note: 1. 2. 3. 4. 5. 6. The batch count value is held at 0 during batch counter reset input. If the batch count set value is 0, batch count will be performed but there will be no batch output. The batch count value returns to 0 when it reaches 999,999 (9,999 for 4-digit models). Once batch input has been turned ON, it will return to the ON state after power interruptions. 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. After batch output turns 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. 27 H7CX-A 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. OUT1 and OUT2 turn ON and OFF simultaneously. Dual Count Calculating Mode = ADD Dual count value = CP1 PV + CP2 PV Dual Count Calculating Mode = SUB Dual count value = CP1 PV - CP2 PV Reset 1 (CP1 reset) Reset 1 (CP1 reset) Reset 2 (CP2 reset) Reset 2 (CP2 reset) Dual count value Dual count set value Dual count value Dual count set value 0 0 CP1 present value CP1 present value 0 0 CP2 present value CP2 present value 0 0 OUT1, 2 Note: The above is for when the output mode is N. * The operation after count completion for the dual counter value is determined by the output mode. * The CP1 present value is reset when reset 1 input is turned ON and the CP2 present value is reset when reset 2 input is turned ON. * If the reset key is pressed while the dual count value, CP1 present value, or CP2 present value is displayed, all of the present values are reset and outputs turn OFF. At this time, counting is not possible for CP1 or CP2 inputs. OUT1, 2 Note: The above is for when the output mode is K-2. SUB mode can be used only when K-2, D, L, or H is selected as the output mode with 6-digit models. Note: 1. Counting is not possible for CP1 during reset 1 input. CP2 will not be affected. The dual count value 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. 28 H7CX-A Reset Function List Function 1-stage/2-stage counter Screen displayed in run mode Present value/ set value (1, 2) Total and preset counter Present value/ set value Batch counter Total count value Present value/ set value Dual counter Batch count Dual count value/batch value/dual count set value count set value Present value and output reset.

For details, refer to page 36. Note: 1. Be sure to set pin 1 of the DIP switch to ON. If it is set to OFF, the DIP switch settings will not be enabled. 2. Changes to DIP switch settings are enabled when the power is turned ON. Advanced-Function Settings After making DIP switch settings for basic operations, advanced-functions (see note) can be added using the operation keys. For details, refer to page 31. Note: Advanced functions consist of decimal point position, prescale value, auto-zero time, startup time, display color, output allocation, and key protect level. 30 H7CX-A Settings for Advanced Functions Note: When using as a tachometer, switch to the tachometer configuration using the procedure given on page 36. Settings that cannot be performed with the DIP switch are performed with the operation keys. Note: 1. If the mode is switched to the function setting mode during operation, operation will continue. 2. Changes made to settings in function setting mode are enabled for the first time when the mode is changed to run mode. Also, when settings are changed, the counter is reset (measured values initialized and output turned OFF) on returning to run mode. Run mode Power ON For details on operations in run mode, refer to page 34. (See note 1.) (See note 2.) The characters displayed in reverse video are the initial values. 3s min. 3s min. When performing settings with operation keys only, set pin1 of the DIP switch to OFF (factory setting). If pin 1 of the DIP switch is set to ON, the setting items indicated by will not be displayed. Set each setting item using the keys. Tachometer output mode (HI-LO) (AREA) (HI-HI) (30 Hz) (10k Hz) (LO-LO) Counting speed Decimal point position (No decimal point) Function setting mode Prescale value (0.001) (One digit after decimal point) (1.000) (Two digits after decimal point) (Three digits after decimal point) (99.999) Average processing (No average processing) Auto-zero time (Average of 2 measurements) (0.1s) (99.9s) (0.0s) (99.9s) Startup time (Average of 4 measurements) (Average of 8 measurements) NPN/PNP input mode (NPN input) (PNP input) (Red) (Green) Display color (Red-green) (Green-red) Output allocation Note: Displayed for H7CX-AU@ models Key protect level (KP-1) (KP-2) (KP-3) (KP-4) (KP-5) 31 H7CX-A Explanation of Functions Tachometer Output Mode (totm) (Setting possible using DIP switch.) Set the output method for control output based on the OUT1/OUT2 set value. Upper and lower limit (HI-LO), area (AREA), 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 35.) Counting Speed (cnts) (Setting possible using DIP switch.) 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. Auto-zero Time (aut=) It is possible to set the H7CX so that if there is no pulse for a certain time the display is force-set to 0. This time is called the auto-zero time. Note: Set the auto-zero time to a time slightly longer than the estimated interval between input pulses and within the setting range (0.1 to 99.9 s). 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. Startup Time (stmr) In order to prevent undesired output resulting from unstable input immediately after the power supply is turned ON, it is possible to prohibit measurement for a set time (0.0 to 99.9 s), the startup time. 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. Display The relationship between display and input is determined by the following equation. Set the prescale value according to the unit to be displayed. Startup time Comparison value (lower limit) Displayed value = f x a f: Input pulse frequency (number of pulses in 1 second) a: Prescale value Time Power supply 1. Displaying Rotation Rate Display unit Output (lower limit) Prescale value (a) rpm 1/N x 60 rps 1/N NPN/PNP Input Mode (imod) 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: Select either NPN input (no-voltage input) or PNP input (voltage input) as the input format. The same setting is used for all external inputs. For details on input connections, refer to Input Connections on page 11. 1. Set the decimal point position to 1 decimal place. Display Color (colr) 2. Using the formula, set the prescale value to 1/N x 60 = 60/5 = 12. Set the color used for the measurement value. 2.

N: Number of pulses per revolution d: Diameter of rotating body (m) d: Circumference (m) Control output ON Red (fixed) Measured value displayed in green when either control output 1 or control output 2 is ON. Measured value displayed Measured value displayed in green when both control in red when either control (See note outputs 1 and 2 are OFF. output 1 or control output 2 2.) is ON. g-r d: Diameter of rotating body Average Processing (aug) (Setting possible using DIP switch.) Flickering display and output chattering can be prevented using average processing (simple averaging). 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. The measurement cycle will be equal to the sampling cycle (200 ms) multiplied by the average processing setting (i.e., the number of times). Average processing enables fluctuating input signals to be displayed stably. Set the optimum number of times for the application. Note: 1. If the tachometer output mode is set to AREA, however, the measured value is displayed in red when control output 1 is OFF and in green when control output 1 is ON. 2. If the tachometer output mode is set to AREA, however, the measured value is displayed in green when control output 1 is OFF and in red when control output 1 is ON. 32 H7CX-A Output Allocation (otst) When using H7CX-AU@ models as 2-stage counter, each output can be flexibly allocated to either stage 1 or 2. Transistor output placed for SV1 and contact output for SV2 or vice verse, as in the following table. H7CX-AU/-AUD1 OUT1 off on OUT2 Transistor (12-13) Contact (3, 4, 5) Contact (3, 4, 5) Transistor (12-13) H7CX-AUSD1 OUT1 OUT2 off Transistor (12-13) Transistor with diode (3, 4, 5) on Transistor with diode (3, 4, 5) Transistor (12-13) Key Protect Level (kypt) Set the 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-5). The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/OFF status of the keyprotect switch after the H7CX is mounted to the panel.

Displaying Speed (setting is performed with DIP switch) Display unit 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 Prescale value (a) m/min d x 1/N x 60 m/s d x 1/N N: Number of pulses per revolution d: Diameter of rotating body (m) d: Circumference (m) 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 details on the operation of the output modes, refer to Output Mode Settings on page 56.) Average Processing Flickering display and output chattering can be prevented using average processing (simple averaging). 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 5 Hz or higher, the measurement cycle 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 enables fluctuating input signals to be displayed stably. Set the optimum number of times for the application. 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 47. Advanced Functions (setting is performed with operation keys) Decimal Point Position (dp) Decide the decimal point position for the measurement value and comparison value. d: Diameter of rotating body Note: If the prescale value setting is incorrect, a counting error will occur. Check that the settings are correct before using this function. Auto-zero Time (aut=) It is possible to set the H7CX-R so that if there is no pulse for a certain time the display is force-set to 0. This time is called the auto-zero time. Note: Set the auto-zero time to a time slightly longer than the estimated interval between input pulses and within the setting range (0.1 to 999.9 s). 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. Startup Time (stmr) In order to prevent undesired output resulting from unstable input immediately after the power supply is turned ON, it is possible to prohibit measurement for a set time (0.0 to 99.9 s), the startup time. 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-R and rotating body are turned ON at the same time. Display Startup time Prescale Value (pscl) It is possible to display the rate of rotation or the speed of a device or machine to which the H7CX-R is mounted by converting input pulses to a desired unit. If this prescaling function is not 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 x a f: Input pulse frequency (number of pulses in 1 second) a: Prescale value Comparison value (lower limit) Time Power supply Output (lower limit) 1. Displaying Rotation Rate Display unit Prescale value (a) rpm 1/N x 60 rps 1/N 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 place. 2. Using the formula, set the prescale value to 1/N x 60 = 60/5 = 12. 53 H7CX-R Key Protect Level (kypt) Set the 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-5). The key protect level is set in the function setting mode. The key protect indicator is lit while the key-protect switch is set to ON. Confirm the ON/OFF status of the key-protect switch after the H7CX is mounted to the panel.

Note: The following precautions are common for all H7CX models. CAUTION Loose screws may occasionally result in fire or malfunction. Tighten the terminal screws securely. The recommended tightening torque is 0.5 N*m. There may occasionally be a risk of explosion. Do not use the product where flammable or combustion gases are present. If the output relay is used beyond its life expectancy, its contacts may occasionally become fused or there may occasionally be a risk of fire. 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. X2/b T T/a Precautions for Safe Use Operating and Storage Conditions * Do not use in locations affected by excessive vibration or shock, or in locations subject to exposure to water or oil. * Do not use the product in locations subject to dust, corrosive gases, or direct sunlight. * Separate the input signal devices, input signal cables, and the product from the source of noise or high-tension cables producing noise. * Separate the product from the source of static electricity when using the product in an environment where a large amount of static electricity is produced (e.g., forming compounds, powders, or fluid materials being transported by pipe). * Organic solvents (such as paint thinner), as well as very acidic or basic solutions might damage the outer casing of the H7CX. * Use the product within the ratings specified for temperature and humidity. * Do not use the product in locations where condensation may occur due to high humidity or where temperature changes are severe. * Store at the specified temperature. If the H7CX has been stored at a temperature of less than -10C, allow the H7CX to stand at room temperature for at least 3 hours before use. X1/a X1 X2 X Auxiliary relay (e.g., MY Relay) * When the product is operated with no-voltage input (NPN input), approximately 14 V is output from the input terminals, so connect a diode if the external power supply is less than 14 V. Sensor This may occasionally cause electric shock, fire or malfunction. Never disassemble, repair or modify the product. This may occasionally cause electric shock, fire or malfunction. Do not allow metal fragments or lead wire scraps to fall inside this product. X1/a 0V Input * Install a switch or circuit-breaker that allows the operator to immediately turn OFF the power, and make sure it is labeled clearly. * The H7CX's panel surface is water-resistive (conforming to NEMA 4, UL Type 4X, and IP66). In order to prevent the internal circuit from water penetration through the space between the H7CX and operating panel, attach a waterproof packing between the H7CX and installation panel and secure the waterproof packing with the Y92F-30 Flush-mounting Adapter. 0.5 to 1 mm It is recommended that the space between the screw head and the adapter should be 0.5 to 1 mm. * Tighten the two mounting screws on the Adapter. Tighten them alternately, a little at a time, so as to keep them at an equal tightness. If the panel screws are tightened unequally, water may ingress inside the panel. Usage Precautions * Make sure that the voltage applied is within the specified range, otherwise the internal elements of the counter may be damaged. * The load current must be within the rated current. * Ensure that the power is turned OFF before changing DIP switch settings. Changing DIP switch settings with the power turned ON may result in electric shock due to contact with terminals subject to high voltages. * Pay attention to terminal polarity to ensure correct wiring. * Make sure that the fluctuation of the supply voltage is within the permissible range. * Apply the power supply voltage through a relay or switch in such a way that the voltage reaches the rated value within 2 s. If the voltage is applied gradually, the power may not be reset or unstable output operations may result. * Set each set value to match the item being counted (or measured). Not matching the content of the set values with the counted (or measured) items may cause unexpected operations resulting in injury or damage to the equipment. * Leaving the H7CX with outputs ON at a high temperature for a long time may hasten the degradation of internal parts (such as electrolytic capacitors). Therefore, use the product in combination with relays and avoid leaving the product as long as more than 1 month with the output turned ON. 59 H7CX Precautions for Correct Use External Power Supply 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). Load current (mA) (DC voltage supply only) 100 20 15 10.8 Power supply voltage (VDC) Power Supplies * Turn the power ON and OFF using a relay with a rated capacity of 10 A minimum to prevent contact deterioration due to inrush current caused by turning the power ON and OFF. * Be sure that the capacity of the power supply is large enough, otherwise the H7CX may not start due to inrush current (reference value: approx. 10 A, 1.5 ms at 26.4 VAC) that may flow for an instant when the H7CX is turned ON. Power Failure Backup All data is stored in the EEPROM when there is a power failure. The EEPROM can be overwritten more than 100,000 times. EEPROM is overwritten when the power is turned OFF or when settings are changed. Conformance to EN/IEC Standards * Specifications call for basic insulation between the power supply and input terminals, between the power supply and output terminals, and between the input and output terminals. (The H7CXA@D is not insulated between the power supply and input terminals.) * Input and output terminals are connected to devices without exposed charged parts. * Input and output terminals are connected to devices with basic insulation that is suitable for the maximum operating voltage. 60 H7CX Safety Precautions (H7CX-A) Precautions for Safe Use Changing the Set Values 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. Response Delay Time When Resetting (Transistor Output) The following table shows the delay from when the reset signal is input until the output is turned OFF. (Reference values) Minimum reset signal width Precautions for Correct Use 0.8 to 1.2 ms 20 ms 15 to 25 ms Output Delay Time Power Supplies When turning the power ON and OFF, input signal reception is possible, unstable, or impossible as shown in the diagram below. Power supply ON OFF 200 ms 0 to 90 ms 5 ms 0 to 1 s The following table shows the delay from when the present value passes the set value until the output is produced. Actual measurements in N and K-2 modes. (Reference values) Control output type Maximum counting speed Output delay time Contact output Input Output delay time 1 ms Impossible Possible Impossible Unstable Unstable 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. NPN output PNP output Transistor output 30 Hz 16.5 to 24.0 ms 5 kHz 3.7 to 5.6 ms 30 Hz 12.0 to 20.0 ms 5 kHz 0.2 to 0.55 ms Note: The above times may vary slightly depending on the mode or operating conditions. Maximum Counting Speed for Batch Counter 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. Load Load + + Power for load Power for load 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. Counter Inductive load + Power for load Operation with a Set Value and Present Value of 0 If the set value and present value are both 0, output will turn ON. Output will turn OFF during reset. Using the Prescaling Function 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. Note: Output will turn ON, however, if a present value overflow occurs (FFFFFF or FFFF). * Setting the prescale value incorrectly may result in incorrect counting operation. Be sure to set the prescale value correctly. 61 H7CX Safety Precautions (H7CX-R) Precautions for Safe Use Changing the Measurement Value The H7CX-R uses a constant read-in system, so the output status is affected when the comparison values are changed during operation such that the present measurement value falls within the range of the upper- and lower-limit comparison values. Turning ON the Power using the Factory Settings 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. Precautions for Correct Use Comparison Value Settings 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. Using the Prescaling Function Setting the prescale value incorrectly may result in incorrect counting operation. Be sure to set the prescale value correctly. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
