Note: The light intensity is low for reasons of power saving.
Elimination of faults, repair
No changes must be made on devices to be operated in certified hazardous areas.
Repairs to the device must only be carried out by specially trained Pepperl+Fuchs
technicians.
Functional check
The function of the valve interface could also be checked without the low-power auxi-
liary valve. For this purpose, a 3 kΩ resistor has to be connected with the output re-
placing the low-power auxiliary valve. In deactivated state, via this resistor a voltage
of approx. 0.3 V and in activated state a voltage of approx. 3 V can be measured. If
the voltage is measured at the open clamps, that means without a resistor connected,
this voltage will always be 6 .8V. ..7 .4V independent of the state adjusted.
Subject to reasonable modifications due to technical advances.
