AuCom EMX3-1600C - General Faults

TROUBLESHOOTING
Display
Possible cause/Suggested solution
RTD/PT100 A~
RTD/PT100 G
The RTD/PT100 set temperature has been exceeded and tripped the soft starter. Identify and resolve
the condition which caused the appropriate input to activate.
NOTE
PT100 B to PT100 G are applicable only if a RTD/PT100 and Ground Fault card is fitted.
Related parameters: 11A~11G, 16O~16U
RTD circuit fail
Indicates that the indicated RTD/PT100 has short circuited. Check and resolve this condition.
Related parameters: None
Starter
communication
(between device and
soft starter)
• There is a problem with the connection between the soft starter and the optional communications
module. Remove and reinstall the module. If the problem persists, contact your local
distributor.
• There is an internal communications error within the soft starter. Contact your local distributor.
Related parameters: 16J
Starter Disable
This is a name selected for a programmable input. Refer to Input A trip.
Thermistor circuit
Check that a PT100 (RTD) is not connected to B4, B5.
The thermistor input has been enabled and:
• The resistance at the input has fallen below 20 Ω (the cold resistance of most thermistors will be
over this value) or
• A short circuit has occurred. Check and resolve this condition.
Related parameters: None
Time-overcurrent
The EMX3 is internally bypassed and has drawn high current during running. (The 10A protection curve
trip has been reached or the motor current has risen to 600% of the motor FLC setting.)
Related parameters: None
Undercurrent
The motor has experienced a sharp drop in current, caused by loss of load. Causes can include
broken components (shafts, belts or couplings), or a pump running dry.
Related parameters: 4C, 4D, 16C
Unsupported option
(function not available
in inside delta)
The selected function is not available (eg jog is not supported in inside delta configuration).
Related parameters: None
Vibration
This is a name selected for a programmable input. Refer to Input A trip.
VZC Fail Px
Where 'X' is 1, 2 or 3.
Internal fault (PCB fault). Contact your local supplier for advice.
This trip is not adjustable.
Related parameters: None
