Possible cause/Suggested solution

Motor Thermistor

The motor thermistor input has been enabled and:

- The resistance at the thermistor input has exceeded 3.6 k

Ω

 for more than one second.

- The motor winding has overheated. Identify the cause of the overheating and allow the motor

to cool before restarting.

- The motor thermistor input has been open.

NOTE

If a valid motor thermistor is no longer used, a 1.2 k

Ω

 resistor must be fitted across

terminals 05, 06.

Related Parameters: 

16-9 Motor Thermistor

Network Comms

The network master has sent a trip command to the starter, or there may be a network communi-
cation problem.
Check the network for causes of communication inactivity.
Related Parameters: 

16-11 Network/Comms

Parameter out of Range

- A parameter value is outside the valid range.

The starter will load the default value for all affected parameters. Press [Main Menu] to go to the
first invalid parameter and adjust the setting.
Related Parameters: None

Phase Sequence

The phase sequence on the soft starter's input terminals (L1, L2, L3) is not valid.
Check the phase sequence on L1, L2, L3 and ensure the setting in 

2-1 Phase Sequence

 is suitable

for the installation.
Related Parameters: 

2-1 Phase Sequence

Power Loss

The starter is not receiving mains supply on one or more phases when a Start Command is given.
Check that the main contactor closes when a start command is given, and remains closed until the
end of a soft stop.
If testing the soft starter with a small motor, it must draw at least 2% of its minimum FLC setting
on each phase.
Related Parameters: None

Starter/Comms

- There is a problem with the connection between the soft starter and the optional communi-

cations 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: 

16-10 Starter/Comms

Thermistor Cct

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.

Check that a PT100 (RTD) is not connected to 05, 06.
Related Parameters: None.

Time - Overcurrent

The MCD 500 is internally bypassed and has drawn high current during running. (The 10 A
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: 2-4, 2-5, and 16-3

Unsupported Option

The selected function is not available (e.g. jog is not supported in inside delta configuration).
Related Parameters: None
