Remote Module Setup
Each remote module features a priority selector ( D ) that permits
control of load-add or load-shed sequence. Priority number is
identified on clear protective barrier. Diagrams of each module are
shown in Status LED’s, later in this manual. Priority 1 is the highest
priority - devices set to this priority will be the first load(s) added or
last load(s) shed in a load management situation. Priority 8 is the
lowest priority.
Priority 9 and 10 are lockouts. Remote module(s) set to these
priorities will remain unpowered during any utility power outage. An
unlimited amount of remote modules can be assigned to priority
9 or 10.
In consultation with the homeowner, set each remote module’s
priority selector switch to the desired priority position. Assign a
different priority to each remote module for optimum operation.
Testing the Automatic Transfer Switch
Turn the utility service disconnect circuit breaker feeding the
transfer switch contactor to the OFF position. The system’s
automatic sequence described below will initiate. To return to utility
power, turn the utility service disconnect circuit breaker to the
ON position.
Utility Fail
The generator senses when utility voltage is below 70 percent of
nominal. Engine start sequence is initiated after 6 second time
delay.
Engine Warm-Up
Time delay to allow for engine warm-up before transfer. Use jumper
on transfer switch control board to select delay of
20 seconds or 50 seconds.
Transfer
Transfer from utility to generator supply occurs after voltage is
above set levels. The transfer switch control board LED lights will
change from green (utility) to red (generator) and the Symphony®
II status light will change blink status from Blink Blink_Pause_Blink
Blink to Blink_Pause_Blink. Minimum engine run time is 5 minutes
after transfer.
Load Management
Five minutes after transfer to generator power, the remote modules
energize connected load(s) if generator power is available, starting
with the highest priority (1) through the lowest priority (8). There is
a 10 second delay between each sequential activation.
The P1 through P8 LED’s (
A ) on the Symphony® II control board
will illuminate to show loads being added.
Loads connected to remote modules set to priorities 9 and 10
remain off for the duration of a utility power outage.
Utility Pickup
Voltage pickup level is 80 percent of nominal voltage.
Retransfer
Retransfer from generator to utility power is approximately 10
seconds after utility voltage supply is above pickup level and
minimum run time is completed. All remote module(s) will remain
OFF for five minutes after the power transfer.
Engine Cool Down
Engine will run for 60 seconds after retransfer.
