. Turn on the preferred source (utility) circuit
breaker. The utility source acceptable light should
now come on as well as the transfer switch on utility
light. If these lights fail to come on recheck your
incoming power to insure you have 240 volts nomi-
nal. If not, troubleshoot your utility source before
continuing.
******************
***** WARNING *****
******************
PERSONAL INJURY HAZARD - Install front cover
in transfer switch before operation. An electrical sys-
tem fault could cause a flash and severe personal
injury.
2. Press and release the
Auto button
on the
engine control module (ECM). The auto mode icon
will appear on the screen. The unit is now ready to
be operated from the Automatic Transfer Switch.
. Turn on the altenate source (generator) curcuit
breaker.
There are two ways to test your transfer switch
operation: WITHOUT a load transfer or WITH a
load transfer.
WITHOUT load transfer (normal exercise)
. Press and release the
Push to Test
button.
The generator set should start immediately. About
5 seconds the generator (alternate source) accept-
able light comes on and stays on.
2. The generator set runs for 20 minutes. The
Transfer Switch does not transfer the load to the
generator set. The
Transfer Switch
on utility (pre-
ferred source) light stays on.
. To bypass the time delay or cancel the test,
press and release the
Push to Test
button again.
4. The generator set stops and the
Generator
acceptacle light goes off.
WITH Load Transfer
. Press and hold the
Push to Test
button until
the generator (alternate source) acceptable light
comes on and stays on. Then release the button.
This will start up your generator set.
This light indicates that the generator is running and
the output voltage and frequency are within accept-
able limits. Under normal conditions this light should
come on in 5 to 0 seconds. If the light does not
come on and stay on a malfunction has occurred.
Either the unit didn’t start or the voltage or frequency
is incorrect. Correct the problem before continuing.
2. About 5 seconds after the generator (alter-
nate source) acceptable light comes on, the auto-
matic transfer switch should transfer the load from
the utility to the generator. At that time the Transfer
Switch
generator acceptable light should come on.
. The generator will stay connected to the load
for about 5 minutes at which time the transfer switch
will transfer the load back to the utility. At the time it
transfers back to utility the Transfer Switch on Utility
light should come on and the Transfer Switch on
generator light should go out. To bypass this five
minute time delay you can press and release the
Push to Test
button again at any time.
4. After the load retransfer to the utility, the gen-
erator will continue to run for about minute (without
a load) and then shut down. The Generator accept-
able light will go off indicating the generator set has
shut down.
This completes the functional test of the transfer
switch and the generator set. If you want the gen-
erator to automatically start press the
Auto
button
on the engine control module of the generator set. If
you have additional work to do or don’t want to leave
the engine generator set in the automatic start mode
press and release the
stop/reset
button on the gen-
erator set. In the off mode the engine generator set
will not start or run automatically.
GENERATOR EXERCISER CIRCUIT
The automatic generator exerciser is configured to
automatically exercise the generator for 20 minutes
once every 4 days.
In order to set and test the exercise circuit the
engine control module must be set in the auto
mode.
SETTING THE EXERCISER CIRCUIT
Press and release the
Automatic Generator Exer-
ciser
button. After about 8 seconds the exerciser
light flashes 4 times to indicate that the exerciser
circuit has been set. The number of flashes indi-
cates the number of days until the next exercise
period. This 20 minute period will occur at approxi-
mately the same time of the day the button was
pressed.
DISABLING THE EXERCISER CIRCUIT
Press and hold the
Automatic Generator Exerciser
button until the light goes off, the light flashes then
goes off.
ENABLING THE EXERCISER CIRCUIT
Press and hold the
Automatic Generator Exerciser
button until the light goes off, the light flashes then
goes off. After about 8 seconds the exerciser light
flashes fourteen times to indicate that the exerciser
circuit has be re-enabled.

***** WARNING *****
******************
WITH A TOTAL POWER FAILURE (UTILITY
POWER FAILS AND THE GENERATOR FAILS TO
START AND RUN) THE EXERCISER MUST BE
RESET AFTER THE POWER IS RESTORED.
CLEARING AN “ERROR” CODE
An error codes occurs on the ASCO control board if
the generator set fails to start or there is some other
malfunction. BOTH Transfer Switch lights will be
blinking together. The Automatic Generator Exer-
ciser light will be blinking a number of times then
pause. This number gives the error code reason
from page 8 of the ASCO 65 owner’s manual. To
clear this code press and release the
Push to Test
button once. Then troubleshoot the problem accord-
ing to the ASCO 65 owner’s manual.
This completes your installation and unit testing.
ALWAYS leave the system in automatic mode unless
servicing the unit. For automatic operation, the auto
mode icon must be displayed on the engine control
module.
DSE 3110 ENGINE CONTROL
PROTECTIONS
When an alarm is present, the Common alarm LED
if configured will illuminate.
The LCD display will
show an icon to indicate the fault.
WARNINGS
Warnings are non-critical alarm conditions and do
not affect the operation of the generator system,
they serve to draw the operators attention to an un-
desireable condition. The icon will appear steady in
the display. Warning alarms are self-resetting when
the fault condition is removed.
SHUTDOWNS
Shutdowns are critical alarm conditions that stop the
engine and draw the operator’s attention to an un-
desirable condition. Shutdown alarms are latching.
The fault must be removed and the STOP/RESET
button pressed to reset the module.
The icon will
appear flashing in the display.
