MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
NOTE
To determine whether it is the remote control module or the generator set that is
malfunctioning, operate or monitor the corresponding control or indicator on the
generator set to see if the correct. Indication is obtained with exception of
synchroscope. When LOCAL REMOTE switch is in REMOTE position, synchroscope
in control room is not operating If operation or indication is correct, the remote control
module is, most probably, at fault. If the generator set still does not operate properly,
the generator set is, most probably, faulty. Refer to Table 3-3 for troubleshooting
procedures for the generator set.
1.
GENERATOR SET SHUTS DOWN (AC AMPERES METER, AC KILOVOLTS METER, AND FREQUENCY
METER READINGS DROP TO ZERO) BUT NONE OF THE FAULT INDICATORS ARE ILLUMINATED.
NOTE
Two persons may be required to perform the following following procedure.
Check bulbs with ANNUNCIATOR TEST pushbutton switch S15R (31, Figure 5-2).
If bulb is defective, replace bulb.
2.
AC AMPERES METER M102R DOES NOT INDICATE CORRECT CURRENT.
Set AMMETER switch S114R to each position and observe AMMETER indication while checking against
generator set AC AMPERES meter M102.
If indication is incorrect In all positions of AMMETER switch S114R, the AC AMPERES meter M103R is,
most probably, at fault (refer to the next higher level of maintenance for replacement). If AC AMPERES
meter M102R indication is correct in at least one position, refer to the next higher level of maintenance.
3.
AC KILOVOLTS METER M101R DOES NOT INDICATE CORRECT VOLTAGE.
Set GEN/BUS VOLTMETER switch S112R to each position and observe AC KILOVOLTS meter M101R
indication while checking against generator set AC KILOVOLTS meter M101.
If indication is incorrect in all positions of GEN/BUS VOLTMETER switch S112R, the AC KILOVOLTS
meter M101R is, most probably, at fault (refer to the next higher level of maintenance for replacement).
If AC KILOVOLTS meter M101R indication is correct in at least one position, refer to the next higher level
of maintenance.
5-7.
OPERATOR MAINTENANCE OF THE REMOTE CONTROL MODULE. This paragraph includes instructions to
assist the operator in maintaining the remote control module. If defective components are noted during inspection, refer
to the next higher level of maintenance for replacement or repair unless noted otherwise. Inspection of the remote
control module consists of performing inspections specified below. Servicing of the remote control module is limited to
cleaning with solvent, P-D80, Type II, or equivalent, and repainting In accordance with MIL-T-704.
a.
AC AMPERES Meter M102R (1, Figure 5-2). .AC AMPERES meter M102R indicates the amount of
current flowing through each individual phase of generator G1. Inspect for cleanliness, broken indicators, and signs of
damage. Check for secure attachment to panel and for chipped, cracked, or loose cover glass.
b.
AC KILOVOLTS Meter M101R (2, Figure 5-2). AC KILOVOLTS meter M101R indicates the voltage
output of generator G1 In a line-to-line condition. Inspect for cleanliness, broken indicators, and signs of damage.
Check for secure attachment to panel and for chipped, cracked, or loose cover glass.
c.
Frequency Meter M103R (3, Figure 5-2). Frequency meter M103R indicates frequency output of
generator G1. Inspect for cleanliness and signs of damage. Check for secure attachment to panel and for chipped,
cracked, or loose cover glass.
