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.
A small rocker switch is located on the
underside of the engine control cabinet.
On gaseous models, the engine timing is
controlled by the ECU on the engine and you
need to tell it what fuel you want to operate
on; LP or NG.
On diesel models, this switch has been
disconnected and will do nothing.
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.
B. ESTOP - & ESTOP +.
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 the jumper installed or a remote N/C switch
installed.
C. BATTERY CHARGER FAILURE.
Battery charger failure relay input from remote battery
charger to DSE 7310 MKII controller.
D. REMOTE DISPLAY PANEL INTERFACE TERMINALS.
These interface terminals are pre-wired to allow for the
connection of a remote display. This display allows for
the remote annunciation of alarms at a location such as a
nurse’s station or a control room. This display can be used
to meet the remote annunciation requirements of the
NFPA 110 standards (this feature meets the annunciation
requirements in applications requiring NFPA 110 level on
protection).
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.
