TROUBLESHOOTING

Display

Possible cause/Suggested solution

Thermistor circuit

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 EMX4e 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: 5C, 5D, 6D

VZC Fail Px

Where 'X' is 1, 2 or 3.
Internal fault (PCB fault). Contact your local supplier for advice.
Related parameters: None

10.3

General Faults

This table describes situations where the soft starter does not operate as expected
but does not trip or give a warning.

Symptom

Probable Cause

Starter "Not Ready"

•

The reset input may be active. If the reset input is
active, the starter will not operate.

"Simul" on display

•

The starter is running simulation software. This
software is intended for demonstration purposes
only and is not suitable for controlling a motor.
Contact your local supplier for advice.

The soft starter does not
respond to the START or
RESET button on the
keypad.

•

The soft starter will only accept commands from the
keypad if parameter 1A

Command Source

is set to

Remote Keypad. Check that the Local LED on the
starter is on.
