ELMON inductive 74-312
Inductive signal transmission system
V10: If no error is present, then LED Power shows the function control (briefly off)
V31 and later: If no error is present, then LED Power shows the operating state (on)
V70 or later:
If an internal fault is determined during operation, the fault alarm will be saved The existing saved
fault alarms are emitted one after the other by the green LED (Power) via the number of pulses All
internally saved fault alarms are deleted after a switch-on process If there is a current internal fault,
then all red LEDs will be continuously lit If there is no current internal fault, the red LEDs display the
state of the connected safety contact strips Any internal faults during testing of signal input (fault
alarm 6) will become inactive if no more errors are discovered during testing
During the output of an error message, the number of output pulses indicates the error:
Pulse Error message
1 Voltage supply outside of the valid value range
2 Inductive signal transmission system error
3 Output control Open faulty
4 Output control Close faulty
5 Data transmission with microcontroller faulty
6 Testing sensor input faulty (stationary safety contact edges) (Open/Close)
