REPHASING CAPACITOR
Since the ballst/lamp system is an inductive load, the circuit has a power factor of about 0.4-0.6. Therefore it is convenient to add a phase capacitor, with appropriate value, connected in parallel to mains.
The capacitor in H.R. systems has also the function to filter and block the ignition voltage peaks which could be transmitted towards mains, producing supply line noise and interferences. If a circuit with autotransformer is used, it is convenient to connect phase capacitor after the autotransformer, thus allowing the use of a smaller size one.
CONTROLS BEFORE SYSTEM STARTING
Follows correctly the schematics reported on ignitor label.
Check that the main supply is correct and within the operating range of ballast/ignitor.
Check the absence of any conductive foreign body close to the parts to which voltage is applied and particularly to HV cable.
STARTING TEST WITHOUT LAMP
Test the system without installing the lamp. At mains switching on, verify that in no part of the luminaire or gearbox are visible sparks or arcings.
Test should be effected in a dark place.
STARTING WITH LAMP
After lamp ignition, wait that system has reached the typical working condition. Then simulate a mains failure (switching off/on the main supply). If lamp doesn't re-start, before replacing the ignitor or the ballast, verify wiring, fuses and that safety door switch operates correctly.
