The protective cover protects the front panel, particularly the
time setting section, against dust, dirt and water drip, as well
as prevents the set value from being altered due to accidental
contact with the time setting knob.
Note: The Y92A-48B Protective Cover is made of a hard plastic and
therefore, must be removed to change the timer set value. However,
since the Y92A-48D Protective Cover is made of PVC, the set value
can be altered by pressing on the surface of the cover.
It may be, however, difficult to make setting changes of the Timer
with the Y92A-48B Protective Cover attached, which must be taken
into consideration before using the Y92A-48B Protective Cover.
When attaching the Y92A-48A to the Timer to be panel-mounted,
use the Y92F-30 Mounting Adapter along with the Timer.
The Protective Cover cannot be, however, used for the H3CA-FA
Series.

Installation

Input Connections
Signal Inputs
Connect the start input contact between terminals C and F, the
reset input contact between terminals C and G, the gate input
contact between terminals C and E, and the check input contact
between terminals C and D.
For each signal input contact, use a gold-plated contacts with high
reliability. Be sure that these input signals satisfy the following
requirements: a resistance of 1 k (max.) and a residual voltage of 1
V (max.) when the contact is made.
Solid-state Signal Inputs
Connect the start input transistor between terminals C and F, the
reset input transistor between terminals C and G, the gate input
transistor between terminals C and E, and the check input
transistor between terminals C and D.
For signal input, use an open collector type transistor with
characteristics: VCEO = 20 V min., VCE(S) = 1 V max., IC = 50 mA min.
and ICBO = 0.5 µA max. In addition, be sure that the input signals
satisfy the following requirements: a resistance of 1 k (max.) and a
residual voltage of 1 V (max.) when the transistor is ON, and a
resistance of 200 k (min.) when the transistor is OFF.

From a solid-state circuit (proximity sensor, photoelectric sensor, or
the like) with rated power supply voltage ranging from 6 to 30 VDC,
input signals can also be applied by other than an open collector type
transistor as shown in the following diagram. The input signal from a
solid-state circuit is applied when output transistor Tr turns ON. In
terms of signal voltage, the signal is input when it goes from a high to
low level. Again, the residual voltage should be 1 V (max.) when the
transistor is ON. As the current output from the timer to Tr is
approximately 0.1 mA, this connection is possible provided the
residual voltage is kept to a maximum of 1 V.
Note: Except for the power supply circuitry, avoid the laying of input
signal wires in parallel or in the same conduit with high-tension
or power lines. It is recommended to use shielded wires or
wiring with independent metal conduits for the shortest
possible distance.

Safety Precautions
How to Change Operation Mode
Operate the pushbuttons of the thumbwheel switch, located at the
leftmost position on the front panel to set the operation mode. Eight
operation modes (A, B, C, D, E, F, G, and H) are selectable and the
selected operation mode is displayed in the operation mode display
window.
How to Change Time Unit and Rated
Time
Operate the pushbuttons of the rightmost thumbwheel switch to
select the desired time unit. Seven time units (0.1 s, s, 0.1 m, m,
0.1 h, h, or 10 h) are selectable and the selected time unit is
displayed in the time unit display window. The desired rated time is
specified by operating the three thumbwheel switches in the middle
of the front panel. The range of rated time is 001 to 999 for each unit.
Time Unit and Rated Time
!CAUTION
1. Do not change the time unit, rated time, or operation mode while
the timer is in operation. Otherwise, the timer may malfunction or
be damaged. Be sure to turn off the power supply to the timer
before changing the timer unit, rated time or operation mode.
2. Note that output will be generated in C, D, E, G, or H mode even if
the rated time is set to 000. No output will be generated in A, B, or
F mode.
Connecting the Operating Power
Supply
The H3CA-8@ contains a capacitor-drop power circuit. Use a
sinusoidal power supply with a commercial frequency. Do not use
power supplies with a high frequency component (such as inverter
power supplies) for Timers with 100 to 240-VAC specifications. Using
these power supplies can damage internal circuits.
The power supply connections to the H3CA-A and H3CA-FA can be
made without regard to polarity for both AC and DC power supplies;
just connect to the specified terminals (2 and 10, or A1 and A2).
When connecting a DC power supply to the H3CA-8 or H3CA-8H,
however, the polarity must be connected as indicated.
Although there is a wide range of power connectable to the H3CA-A
and H3CA-FA, be sure that there is no inductive voltage or residual
voltage applied to the timer power supply terminals (2 and 10, or A1
and A2) when the power switch is turned OFF. (Inductive voltage can
be generated in the power supply line if it is placed in parallel with
high-voltage or power lines.)
A DC power supply can be connected if its ripple factor is 20% or
less and the mean voltage is within the rated operating voltage range
of the Timer.
Connect the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value at once or the Timer may
not be reset or a timer error could result.
H3CA-8 and H3CA-8H Timers with AC specifications are equivalent
to capacitor loads. When switching the Timer power supply with an
SSR, use an SSR with a withstand voltage of twice the power supply
voltage.
Since the H3CA-8 and H3CA-8H Timers of AC specifications
externally discharges a part of internal energy when the power is
turned OFF, it may malfunction if an extremely sensitive relay is used
with the following sequence circuit.
If such a malfunction occurs, change the circuit configuration as
shown below on the right side.

Input/Output
The operation of the output contacts varies with the operation
specifications. Before making connections, check the operation
specifications and operating conditions using the application
examples provided.
The H3CA-A and H3CA-FA do not use transformers. Simultaneous
inputting power from two or more power supplies to separate timers
or counters from a single input contact or transistor is not possible.
For the power supply of an input device, use an isolating transformer,
of which the primary and secondary windings are mutually isolated
and the secondary winding is not grounded.
A transformer is not used in the power supplies for the H3CA-A and
H3CA-FA. You can therefore receive an electrical shock by touching
the input terminals when the power supply voltage is being applied.
Take adequate precautions to protect against electrical shock.
Inputs to input signal terminals are made by shorting the individual
input terminals to the common terminal (terminal 3 for the H3CA-A or
terminal (X) for the H3CA-FA). Internal circuits may be damaged if
connections are made to any other terminals or if voltages are
applied.
If contacts are used to short the terminals, they will be switching a
low voltage (approximately 5 VDC) and current (approximately
100 µA). You must therefore use high-reliability contacts with a
contact resistance of 1 k or less when shorted and residual voltage
of 1 V maximum when shorted.
The reset input will take priority if both the set and reset inputs are
turned ON simultaneously.
Others
Holding relays are used for outputs on the H3CA-A Series. Dropping
the Unit or otherwise subjecting it to shock can cause the relay to
reverse or to move to the center position.
How to Mount the Timer on Mounting
Track
When mounting a H3CA-FA Timer on a socket mounting track,
observe the following procedures:
Mounting
First hook portion A of the timer to an edge of the track and then
depress the timer in direction B.
Dismounting
Pull out portion C with a round-blade screwdriver and remove the
timer from the mounting track.
