Switchgear/Breaker – Manager
Non interlocked Switching
For test purposes, during commissioning and temporarily operations, interlockings can be disabled.
WARNING: Non interlocked Switching can lead to serious injuries or death!
For non interlocked switching the menü [Control\General Settings] provides the following options:
Non interlocked switching for one single command
Permanent
Non interlocked switching for a certain time
Non interlocked switching, activated by an assigned signal
The set time for non interlocked switching applies also for the „single Operation“ mode.
Manual Manipulation of the Switchgear Position
In case of faulty position indication contacts (Aux contacts) or broken wires, the position indication resulted from the
assigned signals can be manipulated (overwritten) manually, to keep the ability to switch the affected switchgear. A
manipulated switchgear position will be indicated on the display by an exclamation mark “!” beside the switchgear
symbol.
WARNING: Manipulation of the Switchgear Position can lead to serious injuries or death!
Double Operation Locking
All control commands to any switchgear in a bay have to be processed sequentially. During a running control
command no other command will be handled.
Switch Direction Control
Switching commands are validated before execution. When the switchgear is already in the desired position, the
switch command will not be issued again. An opened circuit breaker cannot be opened again. This also applies for
switching command at the HMI or via SCADA.
Anti Pumping
By pressing the ON command softkey only a single switching ON impulse will be issued independent, how long the
softkey is actuated. The switchgear will close only once per close command.
