Description of the alarms
CODE DESCRIPTION REASON FOR THE ALARM
A01
NO POWER LINE
All three phases not present when start command given.
A02
PHASE LOSS
One phase not present when start command given or when motor is running.
A03
WRONG PHASE SEQUENCE
Phase sequence does not match setting.
A04
FREQUENCY OUT LIMITS
Frequency of line voltage outside of +-5% tolerance around 50 or 60Hz.
A05
AUX POWER FAILURE
Voltage too low or micro interruption longer than the allowed one.
A06
CURRENT ASYMMETRY
When the motor is running, current asymmetry greater than setting for time longer than setting.
A07
OVERCURRENT TRIP
Current >750%Ie (starter current) for

200msec during starting.
A08
LOCKED ROTOR
Current >500%In (nominal motor current) for

200msec during bypass.
A09
MOTOR LOAD TOO LOW
Motor load torque lower than setting during bypass.
A10
STARTING TOO LONG
Starting time (from start to bypass) longer than setting.
A11
BYPASS RELAY FAULT
Bypass relay contacts did not close or open.
A12
MOT. THERMAL WARNING
Imminent motor protection trip with motor in bypass.
A13
STARTER TH. WARNING
Imminent soft starter protection trip.
A14
MOTOR THERMAL TRIP
Motor thermal protection tripped (inside starter or via PTC input).
A15
STARTER THERMAL TRIP
Heatsink temperature greater than maximum allowed value.
A16
PHASE L1-T1 SHORTED
SCR in short circuit or bypass contactor contacts welded.
A17
PHASE L3-T3 SHORTED
SCR in short circuit or bypass contactor contacts welded.
A18
TEMP. SENSOR FAULT
NTC internal temperature sensor for starter heatsink interrupted or broken.
A19
LINE VOLTAGE TOO LOW
Line voltage L1-L3 lower than setting for set time.
A20
LINE VOLTAGE TOO HIGH
Line voltage L1-L3 higher than setting for set time.
A21
MOTOR CURRENT TOO LOW
Motor current <10%In (In = set nominal motor current) for all three phases.
A22
MAINTENANCE REQUEST
Maintenance interval expired.
A23
COOLING FAN FAULT
No fans detected.
A24
COOLING FAN LOCKED
Fan current too high, rotor probably jammed.
A25
SYSTEM ERROR
Internal error. Please contact Lovato Electric customer service.
UA1..4
USER ALARM
The user alarm was generated by the activation of the variable or of the associated input by means of menu P13.
Programmable input functions table

The following table shows all the functions which can be associated to the programmable digital inputs INPn.
 Each input may be set so as to have inverted function (NO - NC), with energising or de-energising delay with independent set times.

Some functions require a further numeric parameter defined by index (x) specified by parameter P06.n.02 .

See menu P06 Programmable inputs for further details.
