Display 

Possible cause/Suggested solution 

Instantaneous 
overcurrent 

This trip is not adjustable. 
The current on all three phases has exceeded 7.2 times the value 
of parameter 1B 

Motor Full Load Current

. 

Causes can include a locked rotor condition or an electrical fault 
in the motor or cabling.   
Related parameters: None 

Internal fault x 

Where 'X' is a number. 
This trip is not adjustable. 
The EMX4i has tripped on an internal fault. Contact your local 
supplier with the fault code (X). 

Internal fault 88 

The soft starter firmware does not match the hardware. 

Keypad disconnected 

Parameter 1A 

Command Source

 is set to Remote Keypad but the 

EMX4i cannot detect a remote keypad.   
If a remote keypad is installed, check the cable is firmly 
connected to the soft starter. 
If no remote keypad is installed, change the setting of parameter 
1A. 
Related parameters: 1A 

L1 phase loss 
L2 phase loss 
L3 phase loss 

This trip is not adjustable. 
During pre-start checks the starter has detected a phase loss as 
indicated. 
In run state, the starter has detected that the current on the 
affected phase has dropped below 10% of the programmed 
motor FLC for more than 1 second, indicating that either the 
incoming phase or connection to the motor has been lost.   
Check the supply and the input and output connections at the 
starter and at the motor end. 
Related parameters: None 

L1-T1 shorted 
L2-T2 shorted 
L3-T3 shorted 

During pre-start checks the starter has detected a shorted SCR 
or a short within the bypass contactor as indicated. Consider 
using PowerThrough to allow operation until the starter can be 
repaired. 
Related parameters: 6S
