All three neutral connections are made to the appropriate
neutral lugs. These lugs have been prewired common
in the A.T.S. A neutral to ground bond has also been
installed in the A.T.S. panel. If your system requires an
isolated neutral this bond, a copper jumper strap, should
be removed. If this jumper strap is removed remember
to properly ground the Automatic Transfer Switch using
the grounding lug provided.
THREE PHASE POWER MONITOR
All three phase Automatic Transfer Switches have a three
phase power monitor installed in them to monitor each
phase for low voltage. This three phase monitor is
phase rotation sensitive also, and comes from the factory
set up for A-B-C phase rotation. If you have trouble
getting the A.T.S. to pickup the line power on initial
installation, try switching the A and B phase on the
monitor. Your rotation may be C-B-A. If so, be sure to
match the generator rotation to your current normal
power rotation or your three phase motors will try to turn
backwards.

***** WARNING *****
*************
When installing a Three Phase 240 Volt Delta system be
sure you know which lead is the high voltage leg (208
Volt line to neutral). The Automatic Transfer Switch is set
up for the high voltage lead to be connected at G2, T2
and L2 only.
D.C. ELECTRICAL INTERCONNECTION
*******CAUTION******
Never run the AC and DC wiring in the same conduit.
The start circuitry in these A.T.S. is a ground to operate
system. When the power fails the start/stop relay on the
door closes and connects the start wire to battery
negative. If your Engine-Generator set needs any other
type of signal to operate, you will need to contact the
WINCO, Inc. Service Department at 507-357-6831.
Three control wires are required to be installed between
the A.T.S. panel and the generator control. Depending on
the distance 14 to 16 gauge stranded wire should be
sufficient. These wires will be labeled “Bat +”, “Bat -”,
and “Start”. The “Bat+” lead is not used for starting, its
sole purpose is to connect the battery trickle charge back
to the battery on the unit.
SETTING THE EXERCISER CLOCK
Setting the current time and date.
1. Position the top right hand (RUN) slide switch to the
left position.
2. Push the clock’s “Day Select Button” until the clock
displays a triangle under the number corresponding to
the current day of the week. (Monday is day 1, Sunday is
day 7)
3. Push the “Hour Select Button” until the display
indicates the correct time in hours. Note: In the afternoon
you should push the button until a “P” is displayed
beside the correct hour.
4. Push the “Minute Select Button” until the display
indicates the correct time in minutes.
5. Position the top right hand (RUN) slide switch to the
center position. The correct time and date should now
be displayed.
Setting the Exerciser Program:
1. Position the top right hand (RUN) slide switch to the
right hand position.
2. Position the top left hand (AUTO) slide switch to the
center position.
3. Press the “Program Select Button” until No 1 is
displayed on the clock to the right of the time.
4. Push the “Day Select Button” to select the day you
want the engine generator set to start up and run. Note:
You can get more than one triangle displayed on the
clock. If this happens just keep pressing the button and it
will work back through the cycle and display only one
triangle under whichever day you desire.
5. With the “Hour” and “Minute” buttons select the time
of day you want the engine to start up.
6. Press the “Program Select Button” until No. 2 is
displayed on the clock.
7. Push the “Day Select Button” to select the day you
want the engine to stop. This must be the same day you
selected in step 4 above.
8. With the “Hour” and “Minute” buttons, select the time
you want the engine to stop. It is recommended you let
the engine run at least 15 minutes during any exercise
period.
9. Position the top right hand (RUN) slide switch to the
center (RUN) position.
