■I/O Functions
●Inputs
●Outputs
Note: The input and output signals are enabled when power is applied to the Counter. During a power failure, the input signals are disabled, and the output signals are
turned OFF.
Count 9 inputs
•Input count values.
•Used as time count input signal when timer is used.
•Max. counting speed receivable: Count inputs 1 to 7: 30 Hz (Min. signal input width: 16.7 ms), Count inputs 8 and 9: 30 Hz/500 Hz
(Min. signal input width: 16.7 ms/1 ms)
Reset 1 input
•Resets count/time value of a displayed Counter No.
•Counter under reset does not operate as its output is turned OFF.
•Reset signal input received while re-monitor function is ON restores reset count/time value of the specified counter.
•While reset signal is ON, RESET indicator lights.
Short •When the short input is ON, an input is also received for one of the count inputs 2 to 9 when an input is received for count input 1. The
H8BM can thus be used as a multi-stage preset counter without performing external short-circuit wiring.
Counter No. selection •Specifies counter whose count/time value is to be displayed.
I/O inhibit
•Inhibits count inputs of all counters.
•Turns OFF all forecast outputs, RUN outputs, and machine stoppage outputs.
•While I/O inhibit signal is ON, INHB indicator lights.
Forecast 9 outputs
•Each of these outputs turns ON when its forecast value has been reached.
•When a total counter is used, output one-shot signals as carry signals.
•Retain outputs until count values are reset.
RUN 1 output •Turns ON when Counter is operating normally.
Machine stoppage
1 output (Common)
•Turns ON when count value of one counter has reached set machine stoppage value.
•Retains output until count value is reset.

■Installation
●Installation Diagram
To mount the Counter, attach the two supplied brackets to the
left and right sides of the Counter, and securely tighten the
knurled screws on the brackets by hand, keeping the Counter
balanced on the right and left. The performance may not be
satisfactory if the screws are loose or excessively tightened. If
the knurled screws are excessively tightened with pliers or
other tool, damage may result.
M 3×5 screws are used. Select solderless terminals referring
to the figure below.
●Panel Cutouts
The panel cutout is as shown below (according to DIN 43700).
The mounting panel thickness must be 1 to 5 mm. Mount the
Counter so that the ambient temperature will not exceed 55°C.
●Spacing with Other Devices
Provide enough space around the Counter when mounting it
to ensure a proper working space.

Safety Precautions
Refer to Safety Precautions for All Counters.
Fire may occasionally occur. Tighten terminal screws
securely to a tightening torque of 0.5 to 0.6 N·m.
Minor electric shock, fire, or Product failure may
occasionally occur. Do not disassemble, modify, or
repair the Product or touch the interior of the Product.
Minor electric shock, fire, or Product failure may
occasionally occur. Do not allow any pieces of metal
or conductors or any clippings or cuttings resulting
from installation work to enter the Product.
In order to ensure safe operation, be sure to observe the
following points.
(1) Store the Counter within the specified temperature range. If
the Counter has been stored at a temperature under
−10°C, allow the Counter to stand at room temperature for
at least 3 hours before using it.
(2) Use the Counter within the ratings specified for ambient
operating temperature and ambient operating humidity.
(3) Do not operate the Counter in any of the following
locations.
•Locations subject to sudden or extreme changes in
temperature.
•Locations where high humidity may result in
condensation.
(4) Use the Counter within the specified ratings for vibration
and shock.
(5) Do not use the Counter in locations subject to excessive
dust, corrosive gases, or direct sunlight.
(6) When using the Counter in environments subject to large
amounts of static electricity (e.g., pipes carrying molding
materials, powders, or fluid materials), separate the
Counter as far as possible from the sources of static
electricity.
(7) Use the Counter within the specified ratings for vibration,
shock, water immersion, and exposure to oil.
(8) Always use a thermo-switch on the load circuit when a
heater is used.
(9) Do not use organic solvents (such as paint thinner or
benzene), strong alkalis, or strong acids because they will
damage the external finish of the Counter.
(10) Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly
indicate its function.
(11) Be sure that all terminals are wired correctly.
(12) Do not connect more than two crimp terminals to the same
terminal.
(13) Use the specified wires for wiring.
Applicable Wires
AWG22 to AWG14
(cross-sectional area of 0.326 to 2.081 mm2)
Solid or twisted wires of copper
(14) Always maintain the load current within specifications.
(15) Use a switch, relay, or other contact device to turn OFF the
power supply instantaneously. Outputs may malfunction
and memory errors may occur if the power supply voltage is
decreased gradually.
(16) Up to two wires of the same size and type can be inserted
into a single terminal.
(17) Separate the input devices, input wiring, and Counter as far
as possible from sources of noise and power lines carrying
noise.
(18) The life of internal parts may be reduced if Counters are
mounted in close proximity to each other.
(19) Maintain voltage fluctuations in the power supply within the
specified range.
(20) Use a switch, relay, or other contacts so that the rated
power supply voltage will be reached within 0.1 s. If the
power supply voltage is not reached quickly enough, the
power source may fail to reset or the outputs may fall to
operate correctly.
(21) 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).
(22) Periodically inspect and replace the rubber packing. It may
deteriorate, expand, shrink, or harden in some operation
environments.
(23) Check that the backlight, output indicators, and LCD are
operating normally. Some operating environments may
accelerate deterioration of the indicators, LCD, and resin
components and cause display malfunctions. Periodically
inspect and replace parts.
(24) Be sure that the voltage applied is within the specified
range; otherwise, the internal elements of the Counter may
be damaged.
(1) Be sure that the capacity of the power supply is sufficient.
The Counter may not start due to the capacity of the power
supply or the inrush current that may flow for an instant
(approx. 1.6 A for 12 ms) when the Counter is turned ON.
(2) The Power Supply, input, and output circuits are electrically
isolated inside the Counter.
When turning the power ON and OFF, input signal
reception is sometimes possible, sometimes not possible,
and sometimes unstable, as shown in the diagram below.
Turn on or off the operating power source all at once by
using switch or relay contact.
(3) EEPROM is used to back up the memory if the power fails.
Data can be written to EEPROM 100,000 times. Data is
written to the EEPROM when the settings are changed or
deleted or the power is turned OFF.
(4) The Counter uses a constant read-in system, so outputs
will turn ON if the set values are changed during operation
such that the set value is equal to or less than the count
value.
(5) Dispose of the Counter in accordance with all local
industrial waste disposal procedures.
(6) The water and oil resistance will be lost if the front sheet is
peeled off or torn.
Do not use the Counter if the front sheet is peeled or torn.

Operation
Key protection and whether each counter operates as a counter or a timer are specified on a DIP switch provided on the side panel of the
Counter. Open the cover of the switch compartment on the side of the Counter to access the DIP switch.
The system will always enter the RUN mode after the power supply is turned ON.

Note 1. Set the DIP switch (except for Key Protection) before turning
ON the power.
Changes to DIP switch settings while the Counter is operating
will be ignored. Power must be turned OFF then back ON
after changing the settings.
Changes to DIP switch settings are also enabled when
changing to initial setting mode because the same operation
is performed as when cycling the power.
2. Key protection can be set for each key. Key protection will be
