5 Set up the operating parameters
The “setup” switch as well as the jumper selection of the program P1 … P5 may only be
changed after the main power to the controller has been switched off. Before you open the
control unit read the important information in chapter 2!
The set up of operation parameters
can be modified from the front panel with the “setup” switch in the “On” position. Only a trained
and knowledgeable technician should modify the operating parameters
. After setting up the
operation parameters, turn off main power and switch the “setup” switch to the “Off” position to lock
the parameters.
To access the setup switch
: The switch permit setup: “ON”, locks the setup: “OFF”.
 Switch off the main electrical supply before changing the switch position between
“On” and “Off”.
It is not sufficient to switch off the I/O switch on the front panel of the
controller, the external main switch must be switched off to avoid electric shock or possible
damage to the module.
 Open the case cover door and loosen the four big plastic screws at the corners to release
the outer enclosure case.
 Setup switch is located inside the outer enclosure case to the left side of the battery.
The application program is selected at the controller unit (P1, P2, P3, P4, P5). Perform this
operation with the main power supply switched of. Place the “jumper“ in the correct position. Only
one program can be selected at any one time. Double check that the jumper is positioned for the
correct application program!
If the application program is changed (jumper moved) after set up, all parameters switch back to
the default factory setting (chapter 5.1 and 5.2)!
