This manual is for use by qualified personnel only
Exercise Time Sets the time of day that the AGS exercises the generator. Exercise Time requires that
any parameter other than “0” be set in Exercise Period and a value be set in Exercise
Duration.
Relay 3
Function
Sets the function of Relay 3 of the AGS. The function of Relay 3 affects contacts 19
and 20 of the 20-contact connector and external wiring harness. It might be
necessary to manually set Relay 3 according to the make and type of generator being
used. Some diesel generators require preheating of their glow plugs before start
cranking. Setting Relay 3 to Preheat enables Relay 3 to perform this function in
addition to Relay 1.
Generator Run
Hold Time
Specifies the length of time the generator run signal (or B+ or hour meter signal) must
be active before the AGS considers the generator to be running and cranking can be
stopped.
Crank Delay
Time
Specifies the delay time from when the preheat relay is deenergized to when the Start
Relay is energized (and cranking the starter motor).
Crank Time Specifies the maximum length of time the Start relay is engaged (and cranking the
starter motor) for the first attempt to start the generator.
Crank Retry
Time
Specifies the length of time the Start relay is engaged (and cranking the starter motor)
for the second and subsequent attempts to start the generator, in cases when the
generator fails to start on the first attempt.
Preheat Time Specifies how long the Preheat relay is engaged during the start sequence. The
preheat signal may be required for diesel generators with glow plugs or fuel priming
for gas generators.
Generator Start
Attempts
Specifies how many times the AGS attempts to start the generator. This setting is
automatically configured when a Gen Type is selected for the generator. Manually
change this setting only on the advice of the generator manufacturer or authorized
service personnel.
Generator Spin
Down Time
Specifies an interval to be set between a generator stop signal being sent at the end
of a Gen Cool Down cycle and the AGS changing the Generator State to “stopped.”
This setting is automatically configured when a “Gen Type” is selected for the
generator.
Quiet Time Enables/Disables Quiet Time (a period of time during when the generator should not
run).
Quiet Time
Begin
Specifies when Quiet Time begins.
Quiet Time End Specifies when Quiet Time ends.
