Caution!
Protect the terminals from electrostatic discharge. Failure to observe this may result in
destruction of parts of the electronics.
Jumpers J1, J2 and J3 for the hardware setup can be found in the electronic chamber. In order
to set the jumper, open the electronics chamber screwed cover (opposite the connection
chamber cover) and if necessary pull off the display.
Setup or configuration hardware lock using jumper J1
The hardware setup/configuration lock has priority over the software setup.
Setup hardware fault conditioning using jumper J2
The failure mode conditioning setup using the jumper is only active when the microcontroller
fails.
!
Note!
Please check that the hardware and software failure mode conditioning correspond with each
other.
Hardware setup using jumper J3 (only for units without display)
Using jumper 3 the minimum operating voltage can be reduced from 11 V to 8 V.
