■PRESETTING NUMERIC VALUES
Preset values after selecting the function. Values can be preset
whether the power supply is ON or OFF. Continue pressing the and keys until the smallest
digit has been set.
Blinking
To complete presetting, press the key so that no place on
the display is blinking.
*Preset unnecessary higher digits at 0. (i.e. 000015)
The output will go ON if the set value is 0 (0.0 or 0.00) and the
displayed count is also 0 (0.0 or 0.00). In this case, press reset
after presetting, and the output will go OFF.

■POWER SUPPLY CONNECTION
Connect power supply across terminals 2 and 10 and apply
one of the specified voltages. (Pay special attention to the
polarity when using a DC-operated model.)
Cautions
Do not touch the input terminals while power is supplied to
the H8CA-S; otherwise, you will feel electric shock,
because the counter does not have any power transformer
built in. Use of a model rated at a low DC voltage is
recommended when the counter is to be installed at a
location where the input terminals are easily accessible.
Notice:
When connecting external signal input contacts and transis-
tors, use a power supply having a power transformer whose
primary and secondary circuits are isolated from each other
with the secondary circuit not grounded, for the input devices,
to prevent current feedback and short-circuiting.

Notice:
Do not arrange the peripheral circuits of the counter in either
way, as the internal circuit may be destroyed, rendering the
counter unoperational.
To input a signal from a single input contact to several
H8CA-Ss at the same time, be sure to connect the terminals of
the same numbers in parallel.
■TERMINAL ARRANGEMENTS
In counter function mode
Note: When the control power supply is DC, terminals 2 and
3 are internally connected.
Mode switch terminals ( 1& 3 )
When these terminals are short-circuited, set the input and
output modes with the RESET key, not the MODE key.
In timer function mode
Note: When the control power supply is DC, terminals 2 and
3 are internally connected.
* Check the operating status of terminals 3 and 4 (see
table below) before connecting or disconnecting them.
Timer control terminals ( 3& 4 )
Be sure these terminals are not connected when using
H8CA-S as a counter. These terminals are used as shown
below only when H8CA-S functions as a timer.

■POWER FAILURE DETECTION
The H8CA-S is capable of detecting and indicating a power
failure on the display. Before power application or when a
power failure occurs, the “ PW OFF ” display flickers indicating
that the control power supply is off.
Relation among t1, t2, and supply voltage
Operations
Likewise, on power application, there is a period during which
the counter does not respond to the input signal, as shown
below because of a lag in the rise in the internal circuit voltage.
■OPERATION AND DISPLAY
“OUT ” is displayed when counting or timing is completed.
When “ MODE ” lights on display, terminals 1 and 3 are
connected. In this case, it is not possible to preset values. Be
sure to disconnect the terminals.
The H8CA-S uses “regular read format,” so the preset values
can be changed whether power is ON or OFF.
When changing the preset value during timer or counter
operation, a signal will be output when the new value is the
same as the displayed value.
The front panel keys operate at a touch. Do not press the keys
with excessive force or tools, such as a screwdriver. Press only
with fingers.
After presetting values, part of the display might be blinking.
The H8CA-S will operate normally in this condition, but press
the key so that characters do not blink.

■PANEL MOUNTING
Using Y92F-30 adapter for flush mounting
Insert the H8CA-S into a square-cut hole from the front of the
mounting panel; insert the adapter from the rear of the
H8CA-S until the clearance between the panel surface and the
adapter is minimized. Then secure the H8CA-S with two
screws onto the panel.
Mounting
There is no limitation in mounting direction. However, avoid
mounting the unit at an angle.
■SURFACE MOUNTING
Using P2CF-11 front connecting socket
When a number of the H8CA-S are mounted in a vertical line
or when an H8CA-S is mounted close to an obstacle such as a
wiring duct, be sure to provide a separation of approx. 20 mm
(0.79 in.) between adjacent units or between the unit and the
obstacle to allow room for engagement and disengagement of
hooks as shown below.
By attaching the P3GA-11 back connecting socket to a panel
mounted H8CA-S, wiring can be performed in the same
manner as the front connecting socket.
Removal
To remove an H8CA-S panel mounted with a Y92F-30
adapter, loosen the two screws of the adapter, pry up the top
and bottom hooks of the adapter, and pull the H8CA-S out
from the front of the panel.
Caution
The H8CA-S has a built-in lithium battery. Be sure to
dispose of the old H8CA-S properly, as lithium batteries
are likely to explode if incinerated.
When mounting two or more counters in a vertical line,
arrange all the adapters so that the molded springs of the
Y92F-30 adapters are positioned on the right and left sides.
Molded spring
Molded spring
When mounting two or more counters in a horizontal line,
arrange all the adapters so that the molded springs of the
Y92F-30 adapters are positioned on the top and bottom sides.
