Troubleshooting

Symptoms & remedies

SymptomRemedy
Mast light is too hot.Allow light to cool 10-15 minutes before restarting.
Faulty bulb connection.Check that the bulb is tight in the socket.
Bulb broken.Check for broken arc tube or outer bulb jacket, broken or loose components in bulb envelope or blackening/deposits inside tube.
Mast lights off and ballast indicators on control panel are off.Check the connections inside the control box and inside each ballast box.
Generator output incorrect. Check the incoming voltage to the ballast by checking the available voltage on the duplex receptacle. Incoming voltage should be 120V +/- 5V.If voltage is incorrect, engine speed may need to be adjusted or generator may require service. Contact Magnum Products Technical Service Department for more information.
Low transformer output. The voltage from the transformer should read approximately 400 VAC as the light 'strikes' (induces an arc), then drop and slowly rise back up to stabilize at 240-260 VAC.Measure across the junction box terminals when the light is unplugged. If proper voltage is not achieved, perform a capacitor check to determine if the capacitor or coil needs to be replaced.
