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.
*******CAUTION******
Never run the AC and DC wiring in the same conduit.
NOTE: The right hand half of the customer connection
terminal block is for programmable inputs and outputs.
Although these terminals are wired into the DSE7310,
they are not normally programed. This terminal block has
connections for four programmable inputs and four putputs
along with one flex input and a ground. Consult the factory
at 507-357-6831 before attempting to program these inputs/
outputs.
DC Interconnections to the Automatic Transfer Switch
Two control wires are required between the A.T.S. panel and the
generator control terminal box. Depending on the distance, 14 to
16 gauge stranded wire should be used. These wires should be
labeled S1 and S3.
****************
***** WARNING *****
****************
Be sure Engine Generator is in the “OFF” position before you
make any DC interconnections.
ASCO 185 UL SWITCH
Your DC connection points in the ASCO 185 ATS are
terminals “4” and “5 on the interface terminal block. As this is a
“DRY” unpowered contract set it make no difference which lead
(battery negative #1 or start #23) connect to which terminal.
ASCO 300 UL SWITCH
Your DC connection points in the ASCO 300 ATS are terminals
“14” and “15”. Depending on the size of the switch they are
located in different locations. As this is a “DRY” unpowered
contact set it make no difference which lead (battery negative #1
or start #23) connect to which terminal.

3 --- Generator Starting Contacts
The generator starting contacts connections are on the
controller. Refer to the generator manual. Disconnect
the generator battery and verify that the ignition switch is
in the OFF position. Connect the generator starting
wires to the appropriate terminals on terminal block TB7
as shown on the wiring diagram. For wiring convenience
terminal block TB7 has a removable plug. See Figure 4
and Table A.

The time delay and sensor setting in the Group 4
controller are accessible on the inside. Refer to Tables B
and C and to Figures 6 and 7. Use a ball–point pen or
other pointed tool to slide the DIP switch actuators up or
down to match setting shown.
All power must be off before making any changes.
The factory default settings are shown in Table G on
page 5.

5 --- Automatic Generator Exerciser
The built–in automatic generator exerciser can be set to
exercise the generator for 20 minutes once every week.
Clock Battery
Be sure a fresh battery is installed and turned on. It will
maintain the exerciser clock for about 24 hours in case of
a power outage.
Recommended 9 volt alkaline batteries are (see Figure
5):
Duracell MN
1404,
Everready
522,
Panasonic
6AM6
Turn on battery by putting S2 DIP switch actuator 10 in
the on position (up). See Table B and Figure 6.
Exercise with or without Load
The generator should be exercised under load or follow
the recommendations of the generator manufacturer. Be
sure the exerciser is turned on. Then select either
exercise with or without load. The ATS will transfer the
load to the generator when the exercise with load is
selected. See Figure 6 and Table B.

To Set Exerciser
Press and hold (5 seconds) the
Set Engine Exerciser
button. The exercise period occurs immediately and at
approximately the same time weekly thereafter. The
status light below the button blinks during the exercise
period (including the cooldown). The light stays on to
indicate that the exerciser has been set. If the light is off,
the exerciser has not been set.
To Cancel an Active Exercise Period
Press the
Bypass Time Delay
button to stop an exercising
generator. If exercise with load is set, the ATS
retransfers the load to the utility, then stops the
generator after cooldown.
