15.2.9 Information functions
15.2.9.1
Software version
15.2.9.2 Opening data storage
The storage function of the opening data (“TRIP” = opening for protection) is only active if there is an Auxiliary power supply before, during and
after (for at least 1sec.) any power circuit breaker opening due to a trip for protection by the trip unit.
The function and also consultation of the page which shows the last data stored are therefore only available when there is an auxiliary power
supply. In self-supply, the attempt to access the page makes a “function not available” message appear.
In the case of trip for “Iinst”, the page at the side is displayed.
Entering the page from the “Measurements/Trips” menu by selecting “Last Trip”, the last opening carried
out is always presented. Using the
↑
and
↓
keys it is possible to scroll through the last 10 Trips stored by
the unit.
15.2.10 Other functions
15.2.10.1 Programming contacts K51/p1 and K51/p2
The PR113 is fitted with two relays, whose contacts are called K51/p1 and K51/p2.
These can signal different situations, selectable by the user among those listed in the following table.
N° Value Description Notes
1. “ L preal. ” Prealarm of “L”
Active with I > Prealarm Threshold, see par.15.4.3.1
2. “ L timing ” Timing protection “L”
3. “ S timing ” Timing protection “S”
4. “ D timing ” Timing protection “D”
The percentage of contact wear is indicative of the electrical life of the electrical contacts of the EMAX power circuit breaker.
In any case, functionality of the trip unit is in no way modified by the presence of the wear messages.
The prealarm message (wear > 80%, “warning” LED lighting up) indicates that the wear has reached a high value. The alarm message (100%
wear, “emergency” LED lighting up) indicates that it is necessary to check the state of contact wear. The signals are only active with Vaux.
The percentage of wear depends on the number of openings carried out by the power circuit breaker and by the absolute interrupted current during
each of them.
Protection Symbol Protection Symbol Protection Symbol

Number of openings due to the protections and to the TRIP tests
Indication for protection tripped
Value of the currents interrupted on phases (L1, L2, L3), neutral (Ne) and Ground (Gr) not available in the
case of a trip with phase current > 4xIn or I or S with “minimum” time).
Contact wear accumulated.
Value of total interrupted Active power (not available in the case of S, I, D and G trip)
Value of phase voltages (V1, V2 and V3; not available in the case of I trip) and residual voltage (V0; not available
in the case of I or S with “minimum” time trip) at the moment of interruption
This page shows what the software version of the relative PR113 trip unit is.
Each time it is necessary to communicate any unit operating problems to ABB SACE, it is advisable to indicate
the Sw version of the unit (“x.xx”)
