DANGER
Shock Hazard.
Capacitors are capable of discharging high voltage that will
result in death or serious injury. Always turn off the power
switch, unplug the power cord and allow capacitors time to
discharge before servicing.
To check whether the ballast transformer or capacitor has failed:
1. Turn off the power switches, and unplug the power cords
from the wall socket or outlet.
2. Allow capacitors time to discharge.
3. Tip the base up on the wheels so that the mast is on the
ground, and the bottom of the base is vertical.
CAUTION
Tipping the base up without assistance could result in mild to
moderate injury. Assistance is recommended when tipping
the base up.
4. Remove the screws (A, Figure 4) and cover (B) from the
bottom of the base.
5. Check the ballast transformer of each lamp.
1. Connect the power cord to a wall socket or outlet, and
turn on the power switch.
2. Using an AC voltmeter capable of safely measuring up
to 1,000 volts, connect one probe of the voltmeter to
the ground screw (C, Figure 4), and the other probe to
the input side (white wire) of the respective capacitor
(D).
3. The voltmeter should read 550 to 600 volts.
4. Turn off the power switch, and unplug the power cord
from the wall socket or outlet.
5. If the voltage is not in this range, replace the ballast
transformer (E, Figure 4). Contact your authorized
Allmand dealer or the Allmand Service Department for
information on replacing the ballast transformer.
6. Repeat Steps 5-1 through 5-5 for the other ballast
transformer.
6. Check the capacitor of each lamp.
1. Disconnect the lamp fixture cord from the lamp fixture.
2. Connect the power cord to a wall socket or outlet, and
turn on the power switch.
3. Using an AC voltmeter capable of safely measuring up
to 1,000 volts, connect one probe of the voltmeter to
the ground screw, and the other probe to the output
side (black wire) of the respective capacitor (D, Figure
4).
4. The voltmeter should read 360 to 440 volts.
5. Turn off the power switch, and unplug the power cord
from the wall socket or outlet.

6. If the voltage is not in this range, replace the capacitor.
See Ballast Capacitor Replacement .
7. Repeat Steps 6-1 through 6-6 for the other capacitor.
7. Complete replacement of failed part(s).
8. Re-install the cover to the bottom of the base, as removed
in Step 4.
9. Tip the mast up on the wheels so that the base is on the
ground.
10. Test the new ballast transformer and / or capacitor to ensure
proper operation.
