(e)
Remove nuts and lockwashers from mounting studs of replacement meter M103R (3), if installed.
(f)
Install replacement frequency meter M103R (3) and secure with nuts and lockwashers.
(g)
Connect wires to M103R terminals as tagged. Remove and discard tags.
(h)
Tag and disconnect wires from frequency transducer A103R (28, Figure 5-1) terminals.
(I)
See Figure 5-1. Remove hexagon head capscrews (25), hexagonal nuts (26), and lockwashers (27) to
remove frequency transducer A103R.
(j)
Install replacement frequency transducer A103R (28) and secure with hexagon head capscrews (25),
hexagonal nuts (26), and lockwashers (27).
(k)
Connect wires to A103R terminals as tagged. Remove and discard tags.
(I)
Close RCM panel and secure by locking three oval studs across the top of the panel.
d.
AC KILOWATTS Meter M107R (5, Figure 5-2). The AC KILOWATTS meter M107R indicates power output of
generator G1.
(1)
Adjust. Zero Adjust AC KILOWATTS Meter M107R. An adjustment screw on the face of AC KILOWATTS
meter M107R is used to zero the meter when it is not energized.
(2)
Test.
(a)
Start the generator set and set for REMOTE SINGLE SET mode in accordance with Figure 2-22 with
constant output applied to any available stable load.
(b)
Monitor the following quantities off the appropriate RCM meters and record.
1
KW (P) output readout off AC KILOWATTS meter M107R.
2
Voltage (E) output readout off AC KILOVOLTS meter M101R.
3
Current (I) output readout off AC AMPERES meter M102R.
4
Power factor (Pf) readout off POWER FACTOR meter M104R
(c)
Determine accuracy and serviceability of AC KILOWATTS meter M107R by calculation using
quantities recorded in step (b), above. Calculate theoretical power output using the following 3
phase power equation:
(d)
Compare calculated power output against the actual kilowatt readout off AC KILOWATTS meter
M107R. Kilowatt readout off M107R should be within 5.0 percent of the calculated power output. Meter movement
requires 1 millampere DC for full scale meter deflection. If not, replace AC KILOWATT meter M107R.
(3)
Replace.
(a)
Shut down the generator set. See Figure 2-23.
(b)
Open the RCM panel by unlocking three oval studs across the top of the panel.
(c)
Tag and disconnect wires from AC KILOWATTS meter M107R (5), Figure 5-2) terminals.
(d)
Refer to Figure 5-2. Remove nuts and lockwashers from AC KILOWATTS meter M107R (5)
mounting studs and remove meter.
(e)
Remove nuts and lockwashers from mounting studs of replacement meter M107R (5), if Installed.
(f)
Install replacement AC KILOWATTS meter M107R (5) and secure with nuts and lockwashers.
(g)
Connect wires to M107R terminals as tagged. Remove and discard tags.
(h)
Close RCM panel and secure by locking three oval studs across the top of the panel.
