5.3 Controller enable
For controller enable, the following conditions must be fulfilled:
( Controller enable via terminal:
- Independently of the operating mode, apply a voltage of V = +13...+30 V
to X2/28. (Reference potential: X2/39).
( Controller enable via LECOM interface
- For the operating modes C001 = -3-, -5-, -6- and -7- (LECOM control),
the controller must be additionally enabled via the LECOM interface.
( Stop function
- The controller can be inhibited by pressing the STP key. The stop function
can only be reset via the enable command SH + STP or mains switching.
( TRIP reset
- If a monitoring system sets TRIP the controller will be inhibited
immediately. The internal controller inhibit will be reset when resetting the
fault (C067).
Since the controller inhibit can be caused by many different reasons, the origin of
the controller inhibit is displayed under C183.
