Setting Lockout; Tests - Generac Power Systems 006873 Owners & Installation Manual

An example configuration is shown below. Configurations
will vary depending on customer prioritization of loads:
Priority 1 - Baseboard heat
Priority 2 - Air conditioner
Priority 3 - Range
Priority 4 - Dryer
Set the priority of each SMM module as desired
1.
(using the example configuration for reference).
Apply priority decal in a suitable location on
2.
electrical panel
designations.
Record priorities on decal.
3.

Setting Lockout

Most installations will require the lockout switch to be
DISABLED. When performing a whole house backup
with a generator not sized to manage all household
loads, SMM's can be used to disable appliances or
circuits during an outage. For non-essential loads that will
not be used on generator power, set lockout switch to
ENABLED.

Tests

Utility Test
Turn utility power ON and enable all module
1.
feeding circuits.
Verify LED begins to flash at one second intervals.
2.
All contactors will close after five minutes. LED will
3.
illuminate, and stay ON.
Generator Test
Simulate a utility loss by turning main line circuit
1.
breaker (MLCB - service disconnect) OFF while
generator is in AUTO.
All modules will lose power and LEDs will disable.
2.
Generator will power on after preset delay.
3.
All LEDs will flash when generator transfers.
4.
Allow each module to enable output per its priority
5.
setting.
After predefined priority time elapses, each
6.
contactor will CLOSE and LED will illuminate and
stay ON.
Once LED stays ON, press TEST button and verify
7.
load shed occurs.

circuits
Priority 6 - Pool pump or hot
tub
Priority 7 - Other circuits
Priority 8 - Other circuits
to record chosen priority
Section 3: Installation, Tests and Troubleshooting
Once load shed occurs, LED will flash at one
8.
second intervals.
Allow time for each module to enable contactor
9.
output per priority setting.
After predefined priority set time, each contactor
10.
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.
Generator Test with Lockout Switch Enabled
(perform if Lockout Switch Enabled on any
loads)
Simulate a utility loss by turning MLCB (service
1.
disconnect) to OFF while generator is in AUTO.
All modules will lose power and LEDs will disable.
2.
Generator should power on after preset delay.
3.
NOTE: For modules with lockout switch enabled, LEDs
will flash at six second intervals and load will remain
disabled while in generator power.
Return to Utility Test
Return utility power by setting the MLCB (service
1.
disconnect) to ON.
NOTE: All modules should begin flashing at one second
intervals.
NOTE: All modules will recover in five minutes (including
units with lockout switch enabled).
