Conflicting operation
The requirement of setting the panel to either local or remote control prevents
operating the panel locally and centrally at the same time.
For any local operations ─ manual or electrical ─ set the panel to local
control, for example by switching the local-remote switch to LOCAL
position.
Covered control elements
For safety reasons, some of the actuating openings involved in
charging / discharging the spring energy store are covered by the control door.
Open the control door to uncover the actuating openings on the high-
voltage door.
The procedures for charging / discharging the spring energy store manually in panels with motor operating
mechanism control are identical with the procedures in panels without motor operating mechanism control.
For charging / discharging the spring energy store manually, see chapters 10.14 and 10.15.
