10 FUNCTIONAL TESTS
10.5 BRUSHLESS MOTOR FIELD APPLICATION TEST
1. Connect the Va and Vb terminals of the 3-phase voltage source 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 multimeters to TRIP and FCX relay outputs to monitor relay status.
4. Connect a timer to start on MX switch opening and stop on FAR closure to check timing. Repeat with FAR
and FCX respectively for FCX timing.
a) CONFIGURATIONS
Program as defaults shown in Section 5.4: CONFIGURATIONS MENU on page 5–12.
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. Open MX switch
3. FAR contact should close after FAR DELAY expires followed by FCX contact. FIELD IS APPLIED message
should momentarily flash on screen.
