sing. Squeeze the top and bottom of the front bezel between thumb and forefinger
and pull the controller firmly from the housing..

gThe measured value is displayed as standard. At parameter setting, configuration,
calibration level and at the extended operating level, the display changes
cyclically between parameter name and parameter value.
3.2 Behaviour after power-on
After supply voltage switch-on, the unit starts with the operating level.
The unit is in the condition which was active before power-off.
If KS4x-1 was in manual mode before power-off, the controller starts with cor-
recting value Y2 after switching on again.
