Possible cause/Suggested solution 

Thermistor Cct 
(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 Pr: None 

Time-overcurrent 

The Digistart IS 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 Pr: None 

Underpower

 

The motor has experienced a sharp drop in power, caused by loss of load. Causes can include broken 

components (shafts, belts or couplings), or a pump running dry.

The selected function is not available (e.g. jog is not supported in inside delta configuration).

General faults 

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

Table 9-2 General faults 

Symptom 

Probable Cause 

Starter "Not Ready" 

 

Check Input A (DI4, +24V). The emergency stop function may be active. If Pr 

3A

 or 

3F is set to Emergency Stop and there is an open circuit on the corresponding 

input, the Digistart IS will not start.   

The soft starter does not respond to the 

START

 or 

RESET

 button on the keypad. 

 

The soft starter may be in Remote control mode. When the soft starter is in Remote 

control mode, the Local LED on the starter is off. Press the 

LCL/RMT

 button once 

to change to Local control. 

The soft starter does not respond to 

commands from the control inputs. 

 

The soft starter may be in Local control mode. When the soft starter is in Local 

control mode, the Local LED on the starter is on. Press the 

LCL/RMT

 button once 

to change to Remote control. 

 

The control wiring may be incorrect. Check that the remote start, stop and reset 

inputs are configured correctly (see 

Control Wiring

 on page 20 for details). 

 

The signals to the remote inputs may be incorrect. Test the signalling by activating 

each input signal in turn. The appropriate remote control input LED should activate 

on the starter. 

 

The soft starter will only execute a start command from the remote inputs if the 

remote stop and reset inputs are closed. 

The soft starter does not respond to a 

start command from either the local or 

remote controls. 

 

The soft starter may be waiting for the restart delay to elapse. The length of the 

restart delay is controlled by Pr 

6G

 

Restart Delay

 

The motor may be too hot to permit a start. If Pr 

5L

 

Motor Temperature Check

 is set 

to Check, the soft starter will only permit a start when it calculates that the motor 

has sufficient thermal capacity to complete the start successfully. Wait for the motor 

to cool before attempting another start. 

 

The emergency stop function may be active. If Pr 

3A

 or 

3F

 is set to Emergency 

Stop and there is an open circuit on the corresponding input, the Digistart IS will not 

start. If the emergency stop situation has been resolved, close the circuit on the 

input.

Local/Remote

LCL/RMT

 button is enabled. 

 

A reset does not occur after an 

Auto-Reset, when using a remote 

two-wire control. 

 

The remote 2-wire start signal must be removed and reapplied for a re-start. 

Remote start/stop command is overriding 

Auto Start/Stop settings when using 

remote two-wire control. 

 

Auto Start/Stop function should only be used in Remote mode, 3 and 4-wire control. 

Non-resettable Thermistor Cct trip, when 

there is a link between the thermistor 

input TH1, TH2 or when the motor 

thermistor connected between TH1, TH2 

is permanently removed. 

 

The thermistor input is enabled once a link is fitted and short circuit protection has 

activated.   

-  Remove the link then load the default parameter set. This will disable 

the thermistor input and clear the trip. 

-  Place a 1k2 

 resistor across the thermistor input. 

-  Turn thermistor protection to 'Log only' (Pr
