Symbol Flags of measurements
Description
Infinity
Only used with measurements of resistance. Means opening in measured
circuit.
Above the range
Measured value exceeds upper measuring limit
Not available
No measurement, e.g. no measurement channel
Below the range
Measured value exceeds lower measuring limit
Unsure
Measurement value is calculated basing on incomplete information, e.g.
the power is calculated for two phase currents
3.7.
Alarms – cancelling the signaling

Alarms
MUPASZ 710
plus
implements a series of switch bay
protection algorithms. In order to facilitate reading of
operating state of algorithms, the software of MUPASZ
710
plus
device is fitted with the function of displaying
aggregated information on states of all algorithms
implemented in the active profile.
In the
Alarms
window aggregated information on alarms,
locks and tripping is displayed.
The
DELETE
key deletes all signaling and displays
a relevant message.
If the cause of signaling is still active it will not be
cancelled. First the cause should be removed and then the
signaling cancelled.
Signaling may be selectively cancelled by means of the
,
,
key.
An adequate
User command
on the logic scheme may be used to cancel signalization after adaptation.
