MAINTENANCE

The Chromalox STAR-TG tip over cutout with ground fault sensor provides a reliable and cost effective method for sensing ground faults and to shut off the heater in case of tip-over. The pur- pose of the ground fault control is to monitor for ground faults, sense potential heater failure symptoms and to protect equipment.

The current-carrying wires are routed through the current transformer on the control. When ground current reaches the level set by the trip point adjustment, (.03 amps), the relay trips, illumi- nates the tripped LED and provides an output signal which de- energizes the magnetic contactor.

ELECTRIC SHOCK HAZARD. Disconnect all power to heater before installing or servicing kit(s).

Failure to do so could result in personal injury or property damage. Kit(s) must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70.

If heating element(s) fail to operate:

1.Open door of enclosure. DANGER: Hazard of Electric

Shock.

2.If "Tripped" indicator is not on, check for blown fuses or failed electrical components in the heater’s electrical system includ- ing the tip over trip mechanism.then this indicates one or more heating elements are about to fail.

3.Check pendulums on the tip over switch mechanisms to be sure they are not blocked.

4.If the "Tripped" indicator is on, then this indicates one or more heating elements are about to fail. Disconnect power and fol- low the GF Troubleshooting Diagram below.
