condition equals actual condition". If the circuit breaker / switchgear device is in the intermediate position, then
this check is not performed.
Bypassing Interlocking
Bypassing configured interlockings at the time of the switching action happens device-internally via interlocking
recognitions in the command job or globally via so-called switching modes.
• CS=LOCAL
- The switching modes "interlocked" or "unlocked" (non-interlocked) can be set in housing sizes
via the key switch. The position "Interlocking OFF" corresponds to unlocked switching and serves the
special purpose of unlocking the standard interlockings. For devices in housings of size
mode can be changed between "interlocked" and "unlocked" on the operator panel after having entered
the password, or by means of CFC also via binary inputs and a function key.
• REMOTE and DIGSI
- Commands issued by SICAM or DIGSI are unlocked via a global switching mode REMOTE. A separate
request must be sent for unlocking. Unlocking applies for one switching operation only and only for com-
mands caused by the same source.
- Job order: command to object "Switching mode REMOTE", ON
- Job order: switching command to "switching device"
• Derived commands via CFC (automatic command, CS=Auto SICAM):
- Behavior configured in the CFC block ("BOOL to command").
Service Interlocking
The service interlocking function allows you to block all switching operations of the configured switching
devices via the device.
The function is activated as follows:
• "HotLineTag int." using the operation panel or the Web Monitor
• "HotLineTag ext." by a signal from a control center
• ">HotLineTag ext" by an external input signal or CFC
The function is activated by each of these signals. But you can also use several methods simultaneously. The
function is disabled when the last signal has disappeared. "HotLineTag act." is signaled if the service interlock-
ing is active.
If the service interlocking is active, the trip commands of the device are executed. But the automatic reclosing
function (AR) is disabled.
The function is not available with ordering option pos. 10 = A.
Note
Service interlocking only prevents a change of the switching state of the configured switching devices. It does
not mean that the line is automatically de-energized!
