15.6 Warning and error messages
All the messages which can be shown on the display relating to incorrect configurations, generic alarms or deriving from the protection functions
and linked to useful information are described below.
INCORRECT CONFIGURATIONS
MESSAGE
DESCRIPTION
WRONG CS FOR THIS CB A CS size which cannot be installed on the power circuit breaker has been selected (e.g. E1 with 5000A)
ERROR I2 <= I1
The trip threshold of function L is higher than threshold of function S
ERROR I5 <= I1
The trip threshold of function L is higher than threshold of function D
ERROR I3 <= I2
The trip threshold of function S is higher than threshold of function I
ERROR I3 <= I5
The trip threshold of function D is higher than threshold of function I
ERROR: S ZONE SEL.
Zone selectivity for function D has been activated but zone selectivity is already active for function S
ERROR: D ZONE SEL.
Zone selectivity for function G has been activated but zone selectivity is already active for function D
ERROR: V_AUX OFF
The auxiliary power supply is not present - function not available
V_AUX OFF: Comm. OFF
The communication bus is not operating because there is no auxiliary voltage
NO Int. Bus Comm.
The presence of the PR020/K unit is set, but there is no communication on the internal bus
WRONG NE% SELECTION A Neutral protection incompatible with the present CT and power circuit breaker has been selected, or a CT
incompatible with the current Neutral protection and power circuit breaker has been selected.
The condition CT * %Ne (0.5, 1, 1.5 or 2)
≤
“Power circuit breaker continuous current rating” must be valid
NOT available
The function required is not available
CB STATUS ERROR
Current is determined with power circuit breaker status “OPEN”. The status input of the power circuit breaker has
not been cabled correctly (check only carried out with Vaux)
V_AUX Off: S Sel. Off
The unit is configured to operate with zone selectivity S but the auxiliary power supply has been removed
V_AUX Off: G Sel. Off
The unit is configured to operate with zone selectivity G but the auxiliary power supply has been removed
V_AUX Off: D Sel. Off
The unit is configured to operate with zone selectivity D but the auxiliary power supply has been removed
GENERAL ALARMS
MESSAGE
DESCRIPTION
CONTACTS WEAR >80%
The wear on the power circuit breaker electrical contacts has reached 80%
CONTACTS WEAR 100%
The wear on the power circuit breaker electrical contacts has reached 100%
HARMONIC DISTORTION
The current circulating in the power circuit breaker is distorted (peak factor >2.1)
CS-L1 DISCONNECTED
Current sensor relative to phase L1 not connected
CS-L2 DISCONNECTED
Current sensor relative to phase L2 not connected
CS-L3 DISCONNECTED
Current sensor relative to phase L3 not connected
CS-NE DISCONNECTED
Current sensor relative to neutral NE not connected
SA DISCONNECTED
Shunt trip not connected
FREQUENCY OUT OF RANGE
Frequency of the measured current/voltage out of limits
CURRENT > Iw THRESHOLD
Presence of current higher than the free threshold set by user (Iw)
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. 15.4.3.1
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
