5.3 Configuration of the pressure transmitters
The pack controller operates with continuous pressure transmitters with linear characteristic curves. The
pressure inputs can be adjusted for various transmitters with linear characteristic curves. Transmitters with both
current output (4..20 mA) as well as with voltage output (0…10 V) can be used here.
The pressure transmitters can be adjusted in menu 3-1-b using the following parameters:

One of the two possibilities must be selected according to the system configuration.
For transmitters with voltage output, appropriate jumpers must be implemented on the controller, see

! These are preconfigured as 4..20 mA current
inputs at the factory.
