Invalid input signal
Action
Check +24 VDC power supply.
Check anchor plate position.
Action
Adjust Eva position.
Move Eva within sensing distance of
Adam (close door).
Remove metal.
Replace the unit.
Perform procedure to replace Eva. If
fault indication remains, the unit is
defective and must be replaced.
Power cycle (i.e. turn off power, wait for
one minute and turn it on again).
1. Check output signal from the
previous unit in the signal chain.
2. Turn off power supply.
3. Move Eva within sensing distance of
Adam.
4. Power supply.
Power cycle (i.e. turn off power, wait for
one minute and turn it on again). If
fault indication remains, check
incoming signals.
