STARTING PROCEDURE
CONTROL LAYOUT
STOP/RESET - 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.
MANUAL MODE - This button places the module into its Manual
Mode. Once in Manual Mode, the model responds to the Start button
to start the generator and run it off load.
START - Pressing this button from STOP/RESET will start the engine
and run the load.
AUTO MODE - This button places the module into its Auto Mode.
This mode allows the module to control the function of the generator
automatically.
ALARM/LAMP TEST - This button silences the audible alarm in
the controller, de-activates the Audible Alarm output (if configured)
and illuminates all of the LEDs on the module’s face as a lamp test
function.
MENU NAVIGATION - Used for navigating the instrumentation, event
log, and configuration screens.
PROTECTIONS
When an alarm is present, the common alarm LED if configures will
illuminate. The LCD display will show an icon to indicate the failure.
WARNINGS
Warnings are non-critical alarm conditions and do not affect the
operation of the generator system, they serve to draw the operator’s
attention to an undesirable condition. Warning alarms are self-resetting
when the fault condition is removed. The icon will appear steady in the
display.
SHUTDOWNS
Shutdowns are critical alarm conditions that stop the engine and draw
the operator’s attention to an undesirable condition. Shutdown alarms
are latching. The fault must be removed and the STOP/RESET button
pressed to reset the module. The icon will be flashing in the display.
SELECTING THE CORRECT VOLTAGE
A variety of phase voltages are available from the four position selector
switch. The four basic connection patterns are Delta (120/240). Low
or Parallel Wye (120/208), High Wye (277/480), and Single Phase
120/240.
DC INTERCONNECTIONS TO THE ATS
WARNING:
Be sure Engine/Generator is in the OFF position before you make any
DC interconnections.
CAUTION:
Never run the AC and DC wiring in the same conduit.
ASCO 300 UL SWITCH
Your DC connection points in the ASCO 300 ATS terminals “14” and
“15”. Depending on the size of the switch, they are located in different
locations.

A - Customer Remote Start CONNECTIONS TERMINALS.
The
two remote start leads from the Automatic Transfer Switch are
connected to the two terminals marked GROUND & START. The
wire in terminal GROUND is Battery Negative and the wire in the
terminal labeled START is your Remote Start lead. Closing these
two leads together will signal the DSE 7310 to go into an auto-
start mode and start up the engine generator.
Depending on the distance, 14 to 16 gauge stranded wire
should be used. It is suggested that these wires be labeled S1
JURXQGDQG6VWDUW
The terminal blocks are designed to
use terminal lugs on all wires and the screws should be torqued
to 9.6 in. lbs.

B - ESTOP- & ESTOP+.
Remote Emergency Stop terminals.
These two terminals are shipped with a jumper installed. If your
application requires the installation of a Remote Emergency
Stop switch, remove the jumper and wire your switch to these
terminals.
This unit will not start and run without either the
jumper installed or a remote N/C switch installed.
.
C. - Battery Charger Failure.
Battery charger failure relay input
from remote battery charger to DSE7310 controller.
D - Remote Display Panel Interface Terminals.
These
interface terminals are prewired to allow for the connection of a
remote display. This display allows for the remote annunciation
of alarms at a location such as a nurses station or a control
room. This display can used to meet the remote annunciation
requirements of NFPA 110 standards. (
This feature meets the
annunciation requirements in applications requiring NFPA110
level one protection.)
