STOP/RESET (red button) - This button places the
module into its Stop/Reset mode. This will clear any
alarm conditions for which the triggering criteria have
been removed. The fuel supply de-energizes and the
engine comes to a standstill. Should a remote start
signal be present while operating in this mode, a
remote start WILL NOT occur.
AUTO (white button) - This button places the module
into its Automatic mode. This mode allows the module
to control the function of the generator automatically.
The module will monitor the remote start input
and once a start request is made, the set will be
automatically started and placed on load. The module
will then wait until the next start event.
START (green button) - Pressing this button from
STOP/RESET will start the engine and run the load.
PAGE - Pressing this button scrolls the display to show
the various instruments.
With the engine running soothly, check the no load voltage and
frequency wire #1 and #4 on the generator terminal block in the ATS
(L2 and L6 in the ASCO ATS). The voltage should be 240 Volts plus
or minus nominal. The frequency should be between 61.5 to 62 Hertz
(Hz). The Voltage should also be checked between the hot terminals
(L2 and L6) and the neutral connection. The Voltage should be about
one half of the line to line Voltage.
OPERATING SPEED
The engine-generator must be run at the correct speed in order to
produce the proper electrical voltage and frequency.
The speed of the engine was carefully adjusted at the factory so that
the generator produces the proper voltage and frequency. For normal
usage, the speed setting should not be charged. If the generator is
being run continuously on a very light load, it is often advisable to lower
the operating speed slightly.
CAUTION: EQUIPMENT DAMAGE
SPEED ADJUSTMENTS SHOULD ONLY BE MADE BY A QUALIFIED
SERVICE TECH.
NOTICE:
If for any reason during the check out procedures the Voltage and
frequency are not correct, press the red Stop/Reset button and correct
the trouble before proceeding.
After verifying the Voltage and frequency are not correct, press the
Stop/Reset button. This will shut off the engine immediately.
TRANSFER SWITCH & ENGINE-GENERATOR
Automatic (remote) Operation
This procedure checks the electrical operation of the automatic transfer
switch. If the actual operation does not follow procedure, consult the
trouble-shooting section in the transfer switch manual.
1. Turn on the preferred source (utility) circuit breaker. The Utility
Acceptable Light should now come on, as well as the Load on
Utility Light. If those lights fail to come on, recheck your incoming
power to ensure you have 240 Volts nominal. If not, troubleshoot
your utility source before continuing.
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.
3. Turn on the alternate source (generator) circuit breaker.
WARNING: PERSONAL INJURY HAZARD:
Install front cover in transfer switch before operation. An electrical
system fault could cause a flash and severe personal injury.
The digital controller provides sensing, timing, and control functions for
the ATS. This micro-processor-based controller includes built-in control
buttons and status lights for control of the ATS and the generator.
PUSH BUTTONS
On the front control display are the three push buttons that control the
operation of the generator and the ATS.
CAUTION:
Before using the transfer test button, be sure that conditions are safe
for running the generator and for load tester.
TRANSFER TEST
Use this button to test the system. This operation starts the generator
and transfers the load. The controller is shipped with a load transfer set
