PROTECTION FUNCTIONS
MESSAGE
DESCRIPTION
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.
OVERVOLTAGE TIMING
The voltage on at least one phase is above the voltage value of the OV protection threshold and the unit
is under timing
OVERVOLTAGE ALARM
The voltage on at least one phase is above the voltage value of the OV protection threshold, timing is
completed and the protection is in the “ALARM” state
UNDERVOLTAGE TIMING
The voltage on at least one phase is less than the voltage value of the UV protection threshold and the
unit is under timing
UNDERVOLTAGE ALARM
The voltage on at least one phase is less than the voltage value of the UV protection threshold, is completed
and the protection is in the “ALARM” state
RESIDUAL VOLTAGE TIMING
The residual voltage calculated is above the voltage value of the threshold of protection RV protection
threshold and the unit is under timing
RESIDUAL VOLTAGE ALARM
The residual voltage calculated is above the voltage value of the threshold of protection RV protection
threshold, is completed and the protection is in the “ALARM” state
REVERSE A.POWER TIMING
The active power total is less than value of the threshold of protection RP protection threshold and the is
under timing.
UNBALANC. PHASES TIMING
Presence of an unbalance between at least two phases above the value set and the unit is under timing.
UNBALANC. PHASES ALARM
Presence of an unbalance between at least two phases above the value set, 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 load n°1 connected to PR020/K and the unit is under
timing for load opening
K: LOAD 2 TIMING
The current circulating has exceeded the threshold of load 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

15.6.1 In the case of a fault
If it is suspected that the PR113 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. 15.2.11) 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.
