Remote Module Setup; Testing The Automatic Transfer Switch - Briggs & Stratton Dual 200 Amp Manual Del Usuario

Remote Module Setup

Each remote module features a priority selector (A) 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.
NOTICE When setting priorities, use the number on the clear
protective barrier. DO NOT use the number printed on the
control board.
NOTICE When using multiple modules, it is required that separate
priorities (1-8) be used. DO NOT set the same priority level in
multiple modules.
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 owner, 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

WARNING Shock Hazard. Equipment contains high voltage
that could result in death, serious injury and/or
property damage.
• Testing must only be performed by qualified personnel.
• DO NOT operate this equipment imprudently or neglect its
maintenance.
Turn both of the utility service disconnect circuit breakers feeding
the transfer switch contactors to the OFF position. The system's
automatic sequence described below will initiate. To return to utility
power, turn the utility service disconnect circuit breakers 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.
A
Engine Warm-Up
There is a 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 and after the initial warm-up period. 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
will 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 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.
NOTICE Any time the remote module is turned off, even under
utility power, there is a 5 minute delay in power being restored to
the module.
Engine Cool Down
Engine will run for 60 seconds after retransfer.
