Symptoms & remedies

SymptomCauseRemedy
Mast Lights Off, but Ballast Indicators on Control Panel are On.Light fixture is too hot. Faulty lamp connection. Lamp broken Loose lighting connections Damaged or loose electrical cordAllow light to cool 10-15 minutes before restarting. Check that the lamp is tight in the socket. Check for broken arc tube or outer lamp jacket, broken or loose components in lamp envelope, or blackening/deposits inside tube. Check the connections inside the mast junction box and each mast light housing/socket. Check the mast electrical cord for damage and check the cord connections inside the control box.
Mast Lights Off, and Ballast Indicators on the Control Panel are Off.Loose lighting connections Generator output incorrect. Low transformer output.Check the connections inside the control box and inside each ballast box. Check the incoming voltage to the ballast by checking the available voltage on the GFCI receptacle. Incoming voltage should be 120V +/- 5V. If voltage is incorrect, the engine speed may need to be adjusted or generator may require service. The voltage from the transformer should read approximately 400VAC as the light 'strikes' (induces an arc), then drop and slowly rise back up to stabilize at 240-260VAC. On hard wired models, remove the mast junction box cover and insert the wire probes into the connector blocks for the light and ground. If proper voltage is not achieved, perform capacitor check to determine if the capacitor or coil needs to be replaced.
