(13) Check DC SUPPLY, AC SENSING, and FIELD VOLTAGE LEDs on automatic voltage regulator
(11, Figure 4-15). If LEDs are not lit, test backplane module, paragraph 4.8.24.
(14) If measurement recorded in step (9) is above 15 VDC and LEDs checked in step (11) are lit,
automatic voltage regulator (11) is okay.
(15) Shut down generator set, paragraph 2.11.2.
(16) Install DCS control box top panel, paragraph 4.7.2.
c. Removal.
(1)
Shut down generator set, paragraph 2.11.2.
(2)
Open BATTERY ACCESS door (Figure 1-2), and disconnect negative battery cable.
(3)
Remove DCS control box top panel, paragraph 4.7.2.
(4)
Remove CIM. See paragraph 4.8.16.
(5)
Attach ESD wrist strap and connect to ground.
(6)
Remove P24 and P9. Refer to Schematic FO-1.
(7)
Remove locknuts (9, Figure 4-15) and washers (10) securing automatic voltage regulator (11) to
backplane module (20).
(8)
Disconnect leads from R16 and R17.
CAUTION
Automatic voltage regulator is connected to backplane module by a multi-pin
electrical connector. Use care to pull automatic voltage regulator straight out
from backplane module to avoid damage to electrical connector. Failure to
comply can cause damage to equipment.
(9)
Carefully remove automatic voltage regulator (11) from backplane module (20) by pulling straight
out.
d. Installation.
(1)
Carefully align automatic voltage regulator (11, Figure 4-15) with electrical connector on backplane
module (20), and press module connector into backplane connector.
(2)
Secure automatic voltage regulator (11) to backplane module (20) with washers (10) and locknuts
(9).
(3)
Connect leads to R16 and R17.
(4)
