If TEST/Phase = Ub or Uc, the following protective functions are evaluated:
Overvoltage and undervoltage on the appropriate terminals, with dual stage setting, including the Alt
parameters possibility
Note:
When testing on the terminals Ub and Uc, it is always necessary, that the same measurement voltage
as applied on terminals Ub or Uc is also present at the terminals Ua. It is not used for testing purposes, but
serves for the internal synchronization of the measurement process of the unit.
On the first measurement screen (homepage), the sign !!!TEST!!! is displayed in the bottom line instead of
the last trip information.
If any TRIP is performed during the TEST mode, no counters are incremented and the last trip indication and
timer is not affected.
In the TEST mode, it is possible to change setpoints, but some functionality, which is disabled in the TEST
mode (e.g. voltage asymmetry setting or assignment of f(RE)) is not active.
After return from the TEST mode, the unit goes back to its original setting including the outputs assignment
and the setpoint group TEST is hidden.
To return from the TEST mode:
Go to Test mode activation screen and select NO, or
Turn the unit off and on again, or
The unit goes back to the standard operation after 10 minutes from the last keyboard activity.
