Troubleshooting
6Symptoms & remedies
| Symptom | Remedy |
|---|---|
| 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 but ballast indicators on control panel are on | 1. Mast light is too hot. Allow light to cool 10-15 minutes before restarting. 2. Faulty bulb connection. Check that the bulb is tight in the socket. 3. Bulb broken. Check for broken arc tube or outer bulb jacket, broken or loose components in bulb envelope or blackening/deposits inside tube. 4. Check the connections inside the mast junction box and each mast light housing/socket. 5. Check the mast electrical cord for damage and check the cord connections inside the control box. |
| Mast lights off and ballast indicators on control panel are off | 1. Check the connections inside the control box and inside each ballast box. 2. 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, the engine speed may need to be adjusted or generator may require service. 3. 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. On quick disconnect models, measure across the junction box terminals when the light is unplugged. 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. |
| Mast lights on but the light output is low | 1. Fixture or lens are dirty. Clean reflective surface inside fixture and both inside and outside surface of glass lens. Use mild soap and water to clean lens. Other chemicals may have an adverse effect on the glass. 2. Bulb worn due to normal use. Replace bulb. 3. Check the mast coil cord, mast junction box and mast light connections. 4. Generator output incorrect. Check the incoming voltage to the ballast. Incoming voltage should be 120V +/- 5V. If voltage is incorrect, engine speed may need to be adjusted or generator may require service. 5. 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. On quick disconnect models, measure across the junction box terminals when the light is unplugged. 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. |
