D.C. ELECTRICAL INTERCONNECTION
PSS50000 and PSS65000
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 will be labeled S1 and S23.
*************
***** WARNING *****
*************
Be sure both the mode switch on the Engine Generator
and the mode switch in the Automatic Transfer Switch are
in the "OFF" postition before you make any DC intercon-
nections.
The connections to the engine control will be made in a
2" X 4" connection box mounted on the back side of the
generator control box just above the engine control. The
wiring from the engine control has already been stubbed
into this connection box for your convenience. The wires
are labeled as follows:
Battery Negative #1 Yellow Wire S1
Start Signal #23 Yellow Wire S23
Battery Positive* #5 Yellow Wire #5
*Used for a stand alone battery charger only.
The connections in the automatic transfer switch will be
made on a terminal block. This terminal block is located in
the lower right hand corner on the back wall of the switch.
The terminals are labeled S1, and S23.
These control wires MUST NOT be run in the same con-
duit as the AC power leads coming from the generator or
the 120 volt circuit for the battery charger and block heater.

***** WARNING *****
*************
EQUIPMENT DAMAGE - DC connections between
Winco engine generators and other makes of Automatic
Transfer Switches will vary. The Winco engine generator
sets require a relay closure between Battery Negative
(wire S1) and Start ( wire S23) to operate. The Battery
Positive is not used in the A.T.S. panels. Connecting Bat-
tery Positive in any switch can cause permanent damage
to the engine control module
*************
***** WARNING *****
*************
EQUIPMENT DAMAGE - Because these tank heaters
are connected to the water in the engine it is imperative
that you inspect the heater hoses routinely to insure they
are not leaking or deteriorating. A broken heater hose will
drain the coolant out of the engine which could lead to
catastrophal engine failure.
INITIAL START UP
*************
***** WARNING *****
*************
EQUIPMENT DAMAGE - DO NOT jump start these en-
gine generator sets. Starting these units on a low battery
or jump starting them will cause damage to the engine
control module.
Use the following check list to verify correct installation
before starting the engine:
1. Engine oil. Fill as required with proper grade/qty.
2. Engine coolant. Fill as required with proper
mixture.
3. Unit mounting base properly bolted down.
4. Clearance for service and maintenance on all
sides.
5. Proper fuel line material and size.
6. All fuel line connections tight.
7. Fuel line protected and a moisture trap installed
(may be required for N.G.).
8. LP/NG pressure O.K. 4-6 Oz. (7-11" Wc).
9. Battery connections clean and tight.
10. Battery fully charged.
11. All A.C. and D.C. wiring installed and properly
protected.
After completing the above checklist, the engine-gen-
erator set is ready for the initial start-up test.
PROCEDURE
Move the selector switch on the engine generator to the
“RUN” position. The engine-generator will crank and start
automatically. If the engine fails to start, return selector
switch to the “stop” position and correct the trouble before
proceeding.
With the engine running smoothly check the no load volt-
age and frequency at meters on the front panel. The volt-
age should be 240 A.C. and a frequency of 60 (Hz). If you
have the proper voltage at the generator the next step is to
check the voltage at the generator terminals in the Auto-
matic Transfer Switch. The voltage between the G1 and
the G3 terminals should be the same as it was on the front
panel. The voltage should also be checked between the
hot terminals (G1 and G3) and the G-N to be certain of a
balanced voltage output and a solid neutral connection.
The voltage between G1 and G-N should be about one
half of the line to line (G1 to G3) voltage or approximately
120 volts AC. The same approximate voltage should be
found between terminals G3 and G-N (120 volts AC). On
three phase panels the G2 voltage level should also be
checked. ON 240 VOLT (DELTA) SYSTEMS BE SURE
YOU KNOW WHERE THE HIGH VOLTAGE "WILD" LEG
IS. IT MUST BE IN THE SAME LOCATION ON THE LINE
SIDE AS IT IS ON THE GENERATOR SIDE. (i.e. if it's on
L-3 on the line side it must be on G-3 on the generator
side.
