PROTECTION FUNCTIONS
MESSAGE
DESCRIPTION
PREALARM L
The current circulating on at least one phase is above the set prealarm threshold value for protection L -
see par.13.8.1
L PROTECTION TIMING
The current circulating on at least one phase is above the set current threshold value for protection L and the unit
is under timing.
S PROTECTION TIMING
The current circulating on at least one phase is above the set current threshold value for protection S and the unit
is under timing.
G PROTECTION TIMING
The current circulating on at least one phase is above the set current threshold value for protection S and the unit
is under timing.
G ALARM, TRIP OFF
Timing of function G is in progress, but the trip control which is given at the end of the timing has been disabled.
PR020/K
MESSAGE
DESCRIPTION
ERROR Ic2 < Ic1
The current threshold set for load n°1 is higher than that of load n°2 or the current threshold set for reclosing is
higher than that of load opening.
K: LOAD 1 TIMING
The current circulating has exceeded the threshold of lad n°1 connected to PR112/K and the unit is under timing
for load opening.
K: LOAD 2 TIMING
The current circulating has exceeded the threshold of lad n°2 connected to PR020/K and the unit is under timing
for load opening.
K: LOAD 1 CLOSING
Load n°1 connected to PR020/K is about to be reconnected
K: LOAD 1 OPEN
Load n°1 connected to PR020/K has been isolated
K: LOAD 2 OPEN
Load n°2 connected to PR020/K has been isolated
K: AR DISABLED
The auto-reset of load n°1 connected to PR020/K has been disabled

13.17.1 In the case of a fault
If it is suspected that the PR112 is faulty, has malfunctions or has generated an unexpected trip, we advise you to strictly following the
indications below:
1. Do not reset the trip unit.
2. Note down which small magnetic signal is activated (yellow area).
3. If there is Vaux, the trip unit has memorized the trip data, so take these from the Last Trip page.
4. If there is no Vaux, use PR120/B and note down all the settings of the protection functions.
5. Note down the type of power circuit breaker, number of poles, any accessories connected, In, Serial Number (see par. 13.12) and the SW
version.
6. Prepare a brief description of opening (when did it take place? how many times? always under the same conditions? with what type of load?
with what voltage? with what current? can the event be reproduced?)
7. Send/communicate all the information collected, together with the application circuit diagram of the power circuit breaker, to the ABB Assistance
closest to you.
The completeness and accuracy of the information given to the ABB Assistance will facilitate technical analysis of the problem encountered, and
will allow us to carry out all actions useful for the user rapidly.
