Jumper settings
When your input signal is a current of 0-20 mA or 4-20 mA, there is no need to change jumper
settings and you can skip this section.
Where however you intend to use one or both inputs for voltage signals, you must change the
internal jumper settings correspondingly.
To access the jumpers, you have to disconnect the rear screw terminal strips, remove the back
plane from the unit and pull the PCB out of the housing

Wrong jumper settings may cause serious damage to the unit!
After setting the jumpers, please shift the print carefully back to the housing, in order not
to damage the front pins for connection to the keypad plate.
