TROUBLESHOOTING 
The troubleshooting procedures presented in the following chart are designed to assist in fault 
isolation and correction of defects in the Derrick SGX vibrator motor. 
Trouble  Possible Cause  Corrective Action 
Motor fails to run 
Incorrect voltage 
Check that supply voltage agrees with motor 
data plate. If correct, check fuses / circuit 
breakers. Using a voltmeter, check for correct 
supply power to all three phases at starter(s). 
Using a voltmeter, verify that motor starter is 
functioning properly and terminals T-1, T-2, and 
T-3 are energized. Check for damage to power 
cable connected to motor junction box. Correct 
all defects. 
Incorrect power supply 
connections 
Check electrical connections, and correct any 
defects. 
Starter circuit 
overloads and trips 
Incorrect supply 
voltage 
Check that supply voltage agrees with motor 
data plate. 
Incorrect thermal 
overload 
Check that thermal overload is capable of 
handling full load current. Replace overload, if 
inadequate (see motor data sheet for load 
data). 
Mounting hardware 
loose 
Check that mounting hardware is properly 
tightened. 
Vibrating motion of 
motor and related 
components are 
restricted 
Check that shipping brackets have been 
removed or disengaged as required. Check 
condition of float mounts. Verify that solids are 
not preventing motion of the screen frame. 
Correct all defects.
