3) When an error occurs
If a device error is detected, the device will turn the control output (OSSD 1 / 2) OFF. Then the
digital error indicator (red) on the receiver lights up and the fault indicators (yellow) on the emit-
ter and receiver light up or blink.
If an emitter error is detected, the emitter will be locked out, stopping its emission, and the
control output (OSSD 1 / 2) will be turned OFF.
If a receiver error is detected, the receiver will be locked out, and the control output (OSSD 1
/ 2) will go into OFF state. Also, the emission halt indicator (orange) of the emitter lights up.
