6.Trouble Shooting 6.1 Does supply voltage correspond with ballast required voltage? Dual voltage
Guide | ballasts are autoswitching. |
| 6.2 Connect ballast to power supply and test earth (LED “PE” has to be on). |
| 6.3 Check power supply: The three LEDs "L1", "L2" and L3" must be lit to show that all |
| three phases are supplied with line voltage. The red LED "MAINS FAULT" indicates that |
| the Ballast switched off due to line overvoltage ( >270Veff against neutral). Possible |
| cause may be the exchange of one phase with the neutral wire. The ballast will stay in this |
| protection mode until it is disconnected from mains. |
| 6.4 Ensure correct lamp is fitted with correct distribution and cables. |
| 6.5 Ensure ON/OFF Switches are in "OFF" position. Connect the lamp heads with ARRI |
| Splitbox |
| Set ON/OFF switches to "ON". |
| After approx. 1 seconds lamps should ignite. |
| 6.6 If lamp does not strike, the lamp heads safety switch may be broken - check if lens |
| door is fully shut and the lens safety switch is activated. |
| 6.7 Is there a good power supply to the ballast? |
| 6.8 If a ballast / multicore cable / splitbox / luminaire does not work then all four units |
| should be considered faulty. |
| Do not try a suspected luminaire with another ballast - you may end up with two faulty |
| ballasts! |
| To check if a ballast is good, run it with a known good luminaire and known good |
| multicore cable and splitbox. |
| 6.9 If a module cuts out after running a few minutes there are a number of possible |
| failures: |
| • The lamp itself may be faulty or at the end of its life. |
| • The thermal cutout in the module may have activated due to extreme ambient |
| temperature or exposure to direct sunlight in hot summer conditions. |
| • The ventilation might be restricted. In such a case the ballast can be used after it had |
| cooled down and the condition causing the overheating is removed. |
| • If the power supply exceeds the limits or has spikes or dropouts the ballast switches |
| off to protect itself. If running on a generator the output for all three phases should be |
| regulated between 95 - 260V~ (against Neutral). |
| • Earth leakage of luminaires or head to ballast cables will also cause the protection |
| circuit to be activated. Test the module with a known good luminaire. If cables are |
| suspect, they should be exchanged with known good cables. |
| If a ballast is found to be faulty ideally it should be returned together with the luminaire, |
| multicore cable and splitbox to the |
