Selecting Function Mode
Select timer or counter function first. It is not necessary for power
to be ON to set this function. When the H8CA-S is shipped, it is
set to counter function, input mode “A,” output mode “N,” and pre-
set value 1.
1. Terminals 1 and 3 must be connected to select timer or
counter function using the key.
“MODE ” is lit. The function, input mode, or output mode
display will be blinking. (The Power OFF display will stop
blinking when power comes ON.)

Terminal Arrangements
In Counter Function Mode
Note: When the control power supply is DC, terminals ➁ and ➂
are internally connected.
Mode Switch ( ① & ➂ )
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 ➁and ➂
are internally connected.
* Check the operating status of terminals ➂and ➃(see table
below) before connecting or disconnecting them.
Timer Control Terminals ➂& ➃
Be sure these terminals are not connected when using the
H8CA-S as a counter. These terminals are used as shown below
only when H8CA-S functions as a timer.
■Power Supply Connection
Connect power supply across terminals ➁and ➉and apply one
of the specified voltages. (Pay special attention to the polarity
when using a DC-operated model.)
! Caution
Do not touch the input terminals while power is supplied to the
H8CA-S or you may experience an electric shock, since this
counter does not have a built-in power transformer. Use of a
model rated at a low DC voltage is recommended when the
counter is installed at a location where the input terminals are
easily accessible.
Note: When connecting external signal input contacts and tran-
sistors, 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.
Note: Do not arrange the peripheral circuits of the counter in ei-
ther way, as the internal circuit may be destroyed, render-
ing 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 termi-
nals of the same numbers in parallel.

Output Delay Time
The output delay time is the time from the application of the count

put. The delay time differs depending on counting speed and

H8CA-SH8CA-S
Operations
■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
When a power failure occurs, there is a period during which the
counter does not respond to the input signal, as shown below,
because of the lag in the rise in the internal circuit voltage.
Likewise, on power application, there is a period during which the
counter does not respond to the input signal, as show below,
because of a lag in the rise in the internal circuit voltage.
■Operation and Display
“OUT ”is displayed when counting or timing is complete.
When “MODE ”lights on display, terminals 1 and 3 ae connected.
In this case, it is not possible to preset values. Be sure to discon-
nect 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 opera-
tion, 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.
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 wir-
ing duct, be sure to provide a separation of approximately 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.
■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 adaptor is
minimized. Then secure the H8CA-S with two screws onto the
panel.

H8CA-SH8CA-S
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.
When mounting two or more counters in a horizontal line, arrange
all the adapters so that the molded springs of the Y92F-30 adapt-
ers are positioned on the top and bottom sides.
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 witha 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 ex-
plode if incinerated.
