Program setup
The suitable program must be set on the CM-UFD.M21 in accordance with the application. If the
CM-UFD.M21 is sealed/locked (red LED lightning), sealing has to be deactivated first.

Adjustment process:

If present, remove seal (only authorised person)

Apply control supply voltage at A1-A2

Slightly lift the button cover and turn 180°

Actuate the small blue button by strong pressing on the button cover (LED starts flashing)
until the green LED is lightning.
