6.0 TROUBLESHOOTING
6.1 Vibrator Is Not Running
6.1.1 Verify Correct Voltage
1) Verify that the correct voltage is present at the vibrator terminal box; if correct proceed to
section 6.1.2, if not:
2) Verify that main fuses or circuit breakers are "ON".
3) Verify that L-1, L-2 and L-3 terminals of the motor starter(s) are energized.
4) Verify that the motor starter is functioning correctly and that terminals T-1, T-2 and T-3 are
energized.
5) Verify that no failure exists in the flexible cable leading to the vibrator terminal box.
6.1.2 Verify Terminal Connections
If section 6.1.1 is correct, ensure that vibrator terminal connections are correct.
1) Verify that the terminal connections are correct by referring to Figures 2 and 3, if not:
NOTE: Vibrators are normally supplied with dual voltage, 230/460 Volt, 3 Phase, 60 Hz,
windings and must be field connected for a specific voltage. Units are normally connected
for high voltage (460 Volt) from the factory. Check vibrator nameplate data to verify
voltage; some special vibrators are supplied with single voltage windings.
2) Verify that the stator windings are not "open" or,
3) Test windings, to verify they are not "shorted internally" or "shorted to ground".
NOTE: The above tests can be performed with instruments such as resistance measuring
devices and/or a megger.
If sections 6.1.1 and 6.1.2 have been performed and vibrator is still inoperable, please contact
Hindon Corporation for further assistance.
6.2 Vibrator starts but will not continue to run
1) Verify correct motor starter operation:
a) Verify correct "heater" selection based on full load current from vibrator nameplate
or Appendix A - Table A-1.
