Operation ■ E3C-A Timing Chart ■ E3C-A Amplifier Selection of operation mode DARK ON LIGHT ON When light is incident, the output relay operates and solid-state output becomes high (H). DARK ON LIGHT ON 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. 15 2 msec (B) 1 msec (A) The response time is set to 2 ms. 2 msec (B) 1 msec (A) The response time is set to 1 ms. E3C E3C ■ E3C-C AMPLIFIER Selection of operation mode Selection of response time Setting the delay time 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. Selecting timer function ON D. (ON-delay) operation OFF D. (OFF-delay) operation O.S.D.

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.
