Report this condition. Advance the throttle handle. If the ground relay stays in, continue normal operation. On locomotives equipped with a trainline Ground Relay Reset, a tripped relay is indicated by a warning light. Wait 15 seconds before attempting to reset the relay.
Limit reset attempts to two, or as directed by railroad rules.
If the ground relay immediately operates a second time, the affected unit must not be operated. An automatic reset feature is provided which automatically resets the ground relay after two trips have occurred. When the relay trips a third time, it locks out and must be reset using a manual reset button on the control console. Make a visual observation of the locomotive to verify there are no unusual conditions. Press the Trainline Ground Reset button on the control console.
