| Indicators
Emitter | Emitting indicator: Green LED x 2 (light up during emission; one LED lights up for Frequency A setting, both LEDs light up for
Frequency B setting)
Job indicator: Red LED (lights up, blinks or lights off when the job indicator input is applied, selected by operation mode switch) |
|
|
|
|
|
| Indicators Receiver | Operation indicator: Red LED (lights up when one or more beam channels are interrupted)
Stable incident beam indicator: Green LED (lights up when all beam channels are stably received)
Job indicator: Red LED (lights up, blinks or lights off when the job indicator input is applied, selected by operation mode switch)
* When an excess current flows through the output, the stable incident beam indicator and the operation indicator on the receiver blink simultaneously due to operation of the short-circuit protection circuit. |
