malfunction of ballast w/ fluorescent lamps
malfunction of ballast w/ fluorescent lamps
(OP)
Dear friends:
Now I have a trouble with the operation of a ballast and the fluorescent lamps of a comercial refrigerator.
I'm not sure if the ballast is the proper to operate the lamps ( Ballast is ADVANCE Cat. No. RC-2S102-TP and the lamps are -2 pieces- F48T12CWHO 60 Watts), the problem is that when the lightinig system is on, the ballast take 2.1 amps of the line incoming ( normal according nameplate ) but the lamps no start; after a little time, lamps starting very low light intensity, and gradually go up ( but with an increasing line current ), finally the light is very high and the ballast take up 4.8 amps and suddenly the light returns at the initial conditions ( very low light and normal 2.1 amps ) and this becomes a cycle of this conditions of operation.
Can anyone help me?
The trouble begin after the first pair of tubes ( lamps )that were changed after failure by the owner of the apparatus, and he replace them with the tubes refered avobe, and this conditions burn up the ballast, now I'm changed the ballast and I found this abnormal condition of operation,my trouble is that I dont knew the original tubes, and I'm not sure if its are the right replacement.
Thanks in advance.

I'm sure that I don't have voltage drop since I've cheched incoming line volts and output of ballast and boths are OK.
Ballast,contacts and tubes are all new.

Please excuse me, but I can't understand when you said "Rapid start requires a 25 mm grounded conducting plate 25 mm away from the tube as a starting aid ", away from were? Plase can you explain a little more this?
Thanks in advance.
