Cause / remedy
- Display switch-off active
h Press any key
- Parameters have been changed in the
configuration level but not completed.
h Leave the configuration level by pressing
EXIT and wait for a restart.
- Wire break at the analog input or incor-
rect analog input wiring
- Setpoint value configuration incorrectly
configured, e.g. set via interface.
- Input for firing pulse inhibit active
A padlock symbol is shown as the operating
mode in the info line.
Undo connection between screw terminal 7
and 8 at terminal X2_2.
- Load break
h Check load and load connections
- Semiconductor fuse defective due to
short circuit in power section
h Remedy short circuit in the load or load
circuit
h Fit a new semiconductor fuse
- Configuration problem:
even Controller output signal set to 4 to
20 mA and current set to 0 to 20 mA at
analog input of power controller.
h Check configuration and select same
standard signals for the controller and
power controller.
