of the start input. The output is energized when the accumu-
lated time equals the set time. Subsequent start signals during
or after timing will not be accepted. The output relay will remain
energized until a reset input is applied or power is interrupted.

■ SOLID-STATE SIGNAL INPUTS
Input Signal Requirements
Input type Open collector transistor
Voltage when collector is OFF 20 V min.
Saturated voltage when transistor is ON 1 V max.
Collector current 50 mA max.
Input current between collector and base 0.5 µA max.
Resistance when transistor is ON 1 KΩ max.
Residual voltage when transistor is ON 1 V max.
Resistance when transistor is OFF 200 KΩ min.
H3CA-A and H3CA-FA
Solid-state input terminal connections are the same as those
for contact signal inputs.
Solid-State Inputs (Not Open Collector Type)
Proximity and photoelectric sensors often have
NPN or PNP type solid-state output circuits and
rated supply voltages ranging from 6 to 30 VDC.
These signals are applied to the timer according to
the diagram below.
Solid-state circuit (proximity
sensor, proximity sensor, etc.)
(Connect Reset input between
terminals 3 and 7, and Gate
input between terminals 3 and 5.)

(Timer starts

■ CUMULATIVE TIMING
Using the Gate Input with ON-Delay
When the gate signal is closed, timing is temporarily
stopped. When the gate signal opens, timing resumes
at the point of interruption. The gate input terminal
permits the timer to sum up times t1 and t2 as shown
in the timing chart.
t1 + t2 = set time

■ CHECK INPUT
ON-Delay Operation
When a no-voltage input signal is applied to the timer during
the lapse of a set time, the remaining set time will become 0
and the timer will enter the next control state. Also, while the
Check Signal is applied, the elapsed time measurement of the
set time is not performed. The Check input is especially useful
where ON-delay override may be desirable.

Repeat Cycle Operation
The Check input signal in Repeat cycle mode allows
the timer to be used like a binary flip-flop or alternating
relay. Set an unattainable time, such as 999 hours.
Apply the no-voltage Check input to shift output status
from ON to OFF, or vice-versa. Jumper terminals 3 and 6
(X and C1) to short the start function. The Check input
then controls the output relay like a flip-flop or alternating
relay. This may be used to alternate wear on main and
secondary equipment such as pumps.

Installation
■ PROPER INPUT CONNECTIONS (H3CA-A, H3CA-FA)
The neutral or common of the power supply is connected
to terminal 2 (A2) of the timer. Terminal 10 (A1) should be
connected to the "hot" or positive of the power supply. Do
not apply voltage to Check, Gate, Start and Reset inputs.
These are no-voltage type inputs.

■ PROPER OUTPUT CONNECTIONS
Design your control circuit using the output relay contacts to
switch the load. Never switch a load with the contact that
is being used as an input signal. The timer's circuitry may
be damaged.
■ PARALLEL CONNECTIONS
Parallel connection of two or more Omron Timers is possible
as shown by the diagram to the right.
This will allow the simultaneous start or restart of multiple
timers using a single switch for the Start Input and a single
switch for the Reset Input.
It is possible to wire only up to 4 timers in this manner. Wiring
more than 4 results in poor performance due to excessive
voltage drop.
