LOGIC SEQUENCE
Upon a fault of the utility source, the control module proceeds to a preheat function, which acts
both to energize a preheat element on a diesel engine (if equipped) and also acts as a delay to
engine starting (TDES). This time delay prevents unnecessary engine starting and is adjustable
from 0 to 32 seconds. If during the TDES the utility source returns to normal, the control
module simply returns to a monitoring mode.
After the expiration of the preheat/TDES delay, the control module proceeds to crank the engine.
Once the engine starts, the control module proceeds to the time delay normal to emergency
(TDNE). This fixed 4 second time delay begins timing immediately after the engine running
LED illuminates (speed exceeds crank disconnect setting). After the time delay has lapsed, the
control module ensures that the generator frequency is within normal limits (> 55 HZ for 60 Hz
systems, and > 45 HZ for 50 Hz systems). If the generator frequency is within normal limits the
control module signals the transfer switch to immediately transfer to the generator source of
supply.
Once the transfer switch has transferred to the generator source of supply, the control module
then monitors the remote start contacts for a return of the utility. If the utility returns to normal
while the generator is running, the control module proceeds to a 3 minute delay. This is referred
to as time-delay-emergency-to-normal (TDEN). After the TDEN delay, the control module
proceeds to signal the transfer switch to transfer to the utility source of supply. NOTE: If during
the TDEN the utility falls out of the acceptable range again, the control module simply returns to
a normal operation state, and will continue to watch for a return of the utility source and
maintain operation from the generator.
When the TDEN has lapsed, the control module proceeds to initiate transfer to the utility source.
The control module then proceeds to an engine cool-down (TDEC) period. The control module
will continue to run the engine unloaded for a period of 5 minutes. If the utility fails during this 5
minute period (remote start contacts close), the control module proceeds to transfer back to the
generator source after a delay period of 4 seconds.
The user may perform a manual operation of the generator set by placing a user-installed AUTO-
OFF-TEST switch in the TEST position. The control module will proceed to activate the
preheat/TDES. Next, the controller will proceed to crank the engine. However, the transfer
switch will not transfer to the generator source provided the utility source is available. The utility
will always take priority over the generator source. Therefore, during manual starting, the
transfer switch will always stay in the utility position as long as the utility is available. If during
manual operation there is a power failure, the control module will delay a period of 4 seconds
before transferring to the generator.
Should an engine failure occur such as low oil, high temp, overspeed, overcrank, etc, the control
module will latch the fault condition. During this latched state, should the utility return, the
transfer switch will immediately switch back to the utility source to maintain power as soon as
possible to the loads.
