TROUBLESHOOTING PROCEDURES 

This section provides you with guidelines and hints on troubleshooting 

various problems that may be encountered during installation and 
operation of your Tritex Series actuator. 
 

Symptom / Trouble 

Possible Cause / Troubleshooting Procedure 

No response from 
actuator. 

1. Check drive for faults that may indicate problem via 
  I/O or Expert software. 
2.  Check to insure that drive is powered and enabled. 
3.  Check for proper wiring. 

Actuator seems to be 
enabled (receiving 
current) but is not 
operating or is operating 
erratically. 

1. Drive may be improperly tuned. Check all gain  
  settings. 
2. Check for load irregularities or excess compliance. 

Actuator cannot move 
load. 

1. Load is too large for the capacity of the actuator or 
  too much friction is present. 
2. Excessive side load. 
3. Misalignment of output rod to load. 
4. Current limit in drive is set too low 
5. Power supply has too low of current capacity  

Actuator housing moves 
or vibrates when shaft is 
in motion.  

1. Check actuator mounting. Insure that the actuator is 
  securely mounted. 
2. Drive is improperly tuned (wrong gain settings).  

Output rod rotates 
during motion and thus 
does not provide proper 
linear motion. 

1. Install Exlar anti-rotation assembly or incorporate 
  anti-rotation into the application.  

Actuator is overheating.  1.  Insufficient cooling for application requirements. 

  Contact Exlar engineering. 
2.  Ambient temperature is too high. 
3.  Actuator is being operated outside of continuous 
  ratings. 
4.  Amplifier is poorly tuned causing excessive 
  unnecessary current to be applied to motor. Check 
  Gain settings.  
5.  Over Voltage limit set too low causing internal shunt 
  control to remain active.
