10 FUNCTIONAL TESTS

10.9 EXCITER / FIELD VOLTAGE METERING TEST

1. Connect as in Section 10.3: COLLECTOR-RING MOTOR POWER FACTOR TEST on page 10–3 or Sec-
tion 10.6: BRUSHLESS MOTOR POWER FACTOR TEST on page 10–6.
2. Connect DC Voltage source to terminals A20 and A21 (ensure correct polarity).
a) CONFIGURATIONS
Program as defaults shown in Section 5.4: CONFIGURATIONS MENU on page 5–12 except for the following:
• MOTOR: Collector-Ring (if testing for Collector-Ring application)
b) SETPOINTS
Program as defaults shown in 5.2: SETPOINTS MENU on page 5–2.
1. Apply control power to relay and wait for self-test diagnostic to complete. Should get SPM READY mes-
sage and TRIP relay should close.
2. Turn on current source (and function generator for Collector-Ring).
3. Open MX switch
4. FAR contact should close followed by FCX contact. FIELD IS APPLIED message should momentarily flash
on screen.
5. DC VOLTS metered value will now be displayed along with other metered values.
6. Vary DC voltage as in table below and record reading.
