DC CONNECTIONS
All DC connections are completed on the terminal strip
just below the engine control. All DC connection must be
separate conduit. You cannot mix AC and DC leads at the
same conduit.
To install the wires, reference the following picture. Use a
small flat head screwdriver to push the release spring inside
the square hole (A). While the release is being pushed,
insert the wire into the larger circular hole (B). Remove the
screwdriver to secure the wire into place.
REMOTE START
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 MKII to go into an autostart mode
and start up the generator.
Depending on the distance, 14 to 16 gauge standard wire
should be used. It is suggested that these wires be labeled
S1 (ground) and S2 (start). The terminal blocks are designed
to use terminal lugs on all wires and the screws should be
torqued to 9.6 in. lbs.
Note: Any relay closure can be used to start and stop
this generator. As long as the contact stays closed, the
generator set will continue to run. Once the relay is opened,
the unit will shut down and remain on standby mode until
the remote start relay is closed again.
E STOPS
In some applications additional emergency stops may be
desired or necessary. The controller has terminals designed
allowing the addition of multiple remote emergency
stops. E-stops must be normally closed to work properly
in this system. The e-stop circuit supplies power to the fuel
solenoid and the starter circuit. Opening any switch in the
series prevents the engine from cranking or from receiving
fuel to run.

B
To wire additional emergency stop switches first remove
the orange jumper between the two Emergency Stop
terminal blocks. Failure to remove the jumper will prevent
the remote switches from working properly. Add wires
between the terminal block to the new switch(s). The
switches must be wired in series for proper function. Test
each e-stop after wiring to ensure they function properly.
SERIAL COMMUNICATION
DSE provides a series of remote accessories that can help
provide useful information to operators. These accessories
communicate over the DSE Net. Terminal blocks are wired
to the distribution panel to aid in installation. Follow the
instructions included with each accessory.
The generator controller can communicate with a variety
of controls and monitoring systems, including RS232 and
RS485. The ports are wired onto the back of the DSE7310.
In order to finalize communication the program will need
to be adjusted using the free DSE configuration software to
enable the commutation. Contact Winco service for a list of
register values.
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.

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.

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.)
