Tests

Utility Test
1. Turn utility power ON and enable all module
feeding circuits.
2. Verify LED begins to flash at one second intervals.
3. All contactors will close after five minutes. LED will
illuminate, and stay ON.
4. Wait 30 seconds after contactor closes, then press
TEST button and verify module load shed. LED will
flash at one second intervals.
5. Wait five minutes, plus predefined priority set time
for module to recover.
6. Contactor will CLOSE and LED will illuminate, and
stay ON.
Generator/PWRcell Inverter Test
1. Enable Islanding and verify load shed settings.
2. Simulate a utility loss by turning main line circuit
breaker (MLCB - service disconnect) OFF while
generator is in AUTO and inverter is configured
with EnaIslanding ON.
3. All modules will lose power and LEDs will disable
when power is supplied via generator. When

NOTE: Actual test time varies depending on SMM priority setting. Use the
Utility
following formula to calculate test time:
Time = (P-1) x 15 seconds, where P represents priority setting.
Example: SMM Priority 6 test time = (6-1) x 15 seconds, or 75 seconds.

the LED.
4. Generator will power on after preset delay. Inverter
will transfer to Island mode.
5. All LEDs will flash when generator transfers. When
on Inverter power the SMM will go into its
programmed control state.
6. Allow each module to enable output per its priority
setting.
7. After predefined priority time elapses, each
contactor will CLOSE and LED will illuminate and
stay ON.
8. Once LED stays ON, press TEST button and verify
load shed occurs.
9. Once load shed occurs, LED will flash at one
second intervals.
10. Allow time for each module to enable contactor
output per priority setting.
11. After predefined priority set time, each contactor
will CLOSE and LED will illuminate and stay ON.
NOTE: Depending on load size, the SMM module may
immediately go into load shed mode or lockout during
test. In this event, remove one or more higher priority
loads to allow testing of each module.
