(b)
Monitor the following quantities off the appropriate meters on the remote control module and record.
1
Current (I) output readout off AC AMPERES meter M102R.
2
Voltage (E) output readout off AC KILOVOLTS meter M101R.
3
Kilowatt (P) output readout off AC KILOWATTS meter M107R.
4
Power factor (Pf) readout off POWER FACTOR meter M104R.
(c)
Determine accuracy and serviceability of AC AMPERES meter M102R by calculation using the
quantities recorded in step (b), above. Calculate theoretical current output using the following 3
phase equation.
(d)
Compare calculated current output against actual readout of AC CURRENT meter M102R Meter
movement requires 1 milliampere DC for full scale meter deflection. Current readout of M102R
should be within 5 percent of calculated current if not, replace AC CURRENT meter M102R.
(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 AMPERES meter M102R terminals.
(d)
Refer to Figure 5-2. Remove nuts and lockwashers from AC AMPERES meter M102R (1) mounting
studs to remove meter.
(e)
Remove nuts and lockwashers from mounting studs of replacement meter M102R (1), if installed.
(f)
Install replacement AC AMPERES meter M102R and secure with nuts and lockwashers.
(g)
Connect wires to M102R terminals as tagged. Remove and discard tags.
(h)
Close the RCM panel and secure by locking the three oval studs across the top of the panel.
b.
AC KILOVOLTS Meter M101R (2, Figure 5-2). AC KILOVOLTS meter M101R indicates generator output
voltage or bus voltage depending on setting of the GEN/BUS VOLTMETER switch S112R.
(1)
Adjust. With the generator set shut down or the RCM deenergized, check that the AC KILOVOLTS meter
M101R pointer is aligned with the zero adjust point on the meter dial. It necessary, adjust the screw on the meter face to
align with the zero mark.
(2)
Test.
(a)
Start the generator set for REMOTE SINGLE SET operation in accordance with paragraph 2-9 and
Figure 2-22 with constant output applied to any available and stable load.
(b)
Monitor the following quantities off the appropriate RCM meters and record.
1
Voltage (E) readout off AC KILOVOLTS meter M101R.
2
Current I readout off AC AMPERES meter M102R.
3
Kilowatt (P) output readout off AC KILOWATTS meter M107R.
4
Power factor (Pf) readout off POWER FACTOR meter M 104R.
(c)
Determine accuracy and serviceability of AC KILOVOLTS meter M101R by calculation using
metered quantities recorded in step (b), above. Meter movement requires 1 milliampere DC for full
scale meter deflection. Use the equation as follows to obtain theoretical voltage output.
