Selection of operation mode
DARK ON

When light is incident, the output relay
operates and solid-state output becomes
high (H).

When light is interrupted, the output relay
operates and the solid-state output becomes
high (H).
Selection of response time
NOTE: 1. Control output is produced only during the input time.
2. When t exceeds 1 ms or 2 ms, solid-state output is produced. To produce
relay contact output, t must be longer than 20 ms.

Gate input operation
When the gate input terminal 9 is opened at HIGH level (6 to 30
VDC), the output relay performs the timer operation according
to the input signal (light incident or light interrupted).
When the gate input terminal 9 is short-circuited with the 0 V
terminal 2 at LOW level (0 to 2 VDC), the output relay releases
without regard to the input signal or output state. The terminal
generates an inhibit signal.

Alarm Output Timing Chart
The alarm output operates when the control output approaches
critical OFF or ON state for more than 300 ms. An unstable
state occurs when the amount of light incident upon the
receiving element is within 20% of the amount of light needed
to change the control output state.
The alarm output feature is designed to indicate gradual
changes in sensor/reflector position, atmosphere, temperature
or ambient light which result in an unstable control output. A
change occurring less than 300 ms will not cause the alarm
output to operate.
A 300 ms time delay is built into the alarm output circuit. This
prevents false triggering of the alarm output as the leading and
trailing edges of the object to be detected are sensed. The
time can be extended by using an ON-delay timer in the circuit.
