1. Connect the Va and Vb terminals of the 3-phase tester to SPM terminals B9 and B10 (control power and
PF voltage reference) respectively. Program for 120 V AC.
2. Connect the Switch to terminals A11 and A12 of the SPM (MX input). Close switch.
3. Connect the function generator's output (AC sinewave 5 to 10 V) to the VF terminals A18 and A19. Set to
60 Hz.
4. Connect multimeters to TRIP, FAR and FCX relay outputs to monitor relay status. Note: a timer may be
hooked up to start on FAR relay closure and stop on FCX closure to check timing.
a) CONFIGURATIONS
Program as defaults shown in Section 5.4: CONFIGURATIONS MENU on page 5–12 except for following
exceptions
•
MOTOR: Collr-Ring
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. Set function generator to 60 Hz and turn on.
3. Open MX switch
4. Lower frequency to 5 Hz: Relay should not apply field.
5. Lower frequency to just under 3 Hz (5% of 60 Hz). FAR contact should close followed by FCX contact 1
second later. FIELD IS APPLIED message should momentarily flash on screen.
