Troubleshooting
5.1 General
The Tilt Switch control system has been designed to operate under normal Industrial
environments. The majority of
failures encountered have been the result of excessive
vibration, misapplication of the probe or switching excessive currents of voltages.
the operation of the Control unit may be checked by following the procedure.
Caution: when following the procedure, remember that if the unit is controlling other
equipment, the equipment concerned will either be shut down or started up, depending on
the application.
5.2 Troubleshooting Procedure
(1) Check supply voltage. The proper voltage must be applied to Terminals 1 and 2
(110VAC) or 1 and 3 (220VAC).
(2) Disconnect probe wires at Terminals 5 and 6.
(3) Turn time delay control (– DELAY –) completely CCW.
(Remember where it was set so that it may be returned to the same setting).
(4) Short across Terminals 5 and 6 (in tilt switch mode only). (There are no hazardous
voltages at these terminals). If the unit is operating properly, the following will
occur:
The relay will reverse its state.
The light that was illuminated will be de-energized and the one that was de-
energized will be
illuminated.
Relay operation may also be checked by disconnecting wires at
Terminals 7, 8 and 9 or 10, 11 and 12, and connecting an ohm-meter at
the terminals.
