POS Indicators wiring
In the menu [Control/Breaker/Pos Indicators wiring], the signals for the switchgear status indication (position and ready)
are to be assigned.
Position Indication with two contacts - 52a and 52b (recommended)
To identify the current position of the switchgear, the switchgear contact outputs have to be used (called 52a/52b at a
breaker). The Position Indication can work on either one or both of these inputs. Nevertheless, it is recommended that
both are used.
The protective device monitors and evaluates continuously the Status of the Input Signals CinBkr52a-I and CinBkr52b-I.
These signals are validated based on the supervision timers »
t-Move CLOSE« and »t-Move OPEN« validation
functions. As a result, the breaker position will be detected by the following signals:
Pos CLOSE;
Pos OPEN;
Pos Indeterm;
Pos Disturb; and
Pos State (0, 1, 2 or 3).
CLOSE initiated (Supervision)
When a CLOSE command is initiated, the »
t-Move CLOSE« timer will be started. While the timer is running, the »P
OS
I
NDETERM
« State will become true. If the command is executed
and the breaker has reached the end position before
the
timer has elapsed, »P
OS
CLOSE« will become true. Otherwise, if the timer has elapsed »P
OS
D
ISTURB
« will become true.
OPEN initiated (Supervision)
When an OPEN command is initiated, the »
t-Move OPEN« timer will be started. While the timer is running, the »P
OS
I
NDETERM
« State will become true. If the command is executed and
the breaker has reached the end position before
the
timer has elapsed, »P
OS
OPEN« will become true. Otherwise, if the timer has elapsed »P
OS
D
ISTURB
« will become true.
