Accessory 11BG
for Series 300
Installation
Accessory 11BG module includes a programmable engine–
generator exerciser and power source availabil ity contacts. It
can be added to a Series 300 Automatic Transfer Switch (ATS)
that has a Group 1 Controller. If an existing engine exerciser
(Acc. 11CD) is already installed, it must be disconnected first.
TheAccessory11BGmodulemountsdirectlybehindthe
Series 300 ATS opera tor interface on the inside of the
enclosure door. The module connects to the Series 300 ATS
operator interface board and Group 1 controller.
Kits K629830 & K749999 include the Acc. 11BG module,
mounting hardware, and all necessary wiring.
Tools 1/4”, 5/16” nutdrivers, small blade screwdriver
required: your Series 300 ATS Operator’s Manual
for setting the DIP switches
ELECTROCUTION – FLASH HAZARD
Do not work on the transfer switch until
both the utility and generator are off.
Turn OFF both circuit breakers.

Module Installation –Figures2&3
1. With all power OFF, open the enclosure door. Locate
the operator interface (membrane controls) mounted
on the inside of the enclosure door. Use a 5/16”
nutdriver to remove (counterclockwise) the four hex
nuts from the corners of the operator interface. Do not
remove the operator interface board (Figures 2 & 3).
2. Install (clockwise) four standoffs (from the kit) onto
the four studs and tighten them with a 1/4” nutdriver.
3. Install the Acc. 11BG module on top of the operator
interface so that four standoffs fit through the corner
holes. Then install (clockwise)four 6–32 hex nuts (from
thekit)tosecuretheassembly.Tightenthenuts.

mounted on the enclosure door (back view).
Step 1
Connecting the Module – Figures 1, 2, 4
1. With all power OFF, locate the two ribbon cables and
note direction and orientation of each cable.
2. Unplug the ribbon cable (coming from the Controller)
from the operator interface (J3 lower right side) and
reconnect it (same orientation) to the Acc. 11BG module
(J1 lower right side). See Figures 1, 2, & 4.
3. Connect the new ribbon cable (coming from the Acc.
11BG module upper right side) to the operator interface
(J3 lower right side) with the same orientation as the
original cable that was moved. See Figures 2 & 4.
4. Strip the insulation from both ends of the #16 gauge
white wire (from the kit). Connect this prepared wire
between A c c . 11BG module terminal 9 (right side) and
the Group 1 Controller terminal 4 (bottom left). Figure 4.

Programmable Engine–Generator Exerciser
Note: Refer to your Series 300 ATS Operator’s Manual
to set DIP switches S1 & S2 in the Group 1 Controller.
A backup battery
(see Operator’s Manual, Sections 4 and 5) must be turned
on to maintain the settings and to allow programming with
the normal and emergency power sources turned off.
TheAcc.11BGmoduleincludesaprogrammablegenerator exerciser that provides for weekly or biweekly operation. The exerciser may have to be turned on (enabled) by
setting S1 DIP switch actuator 7 to OFF (left position), and
S2 DIP switch actuator 5 to OFF (left position).
The programmable engine–generator exerciser incorporates a 7–day or 14–day time base. Proper Group 1
Controller settings must be made to determine whether or
not the test will be done with or without load transfer
(S1 DIP switch actuator 8).

How to Set Optional Programmable Engine Exerciser (part of Acc. 11BG module)
Start Time Display
Hazardous voltage capable of causing shock,
burns, or death is used in this transfer switch.
Deenergize both Normal & Emergency power
sources before programming the exerciser.
Navigating the Menu
Use the UP and DOWN arrow keys to move through the
displays.
Fast/Slow Adjust
The Start Time Display shows the engine exerciser start
time. There are four parameters that determine the start
time:
weekly (”Every”) or bi–weekly (”Alt”) operation
day of week (”Sun” through “Sat”)
start hour (0 through 23)
start minutes (0 through 59)
For example, if the user wants the exerciser to run every
other Saturday at 3 PM, the proper configuration would be:
“Alt Sat @ 15:00”
NOTE: When choosing bi–weekly operation, the exerciser
will always run on the week designated “(1)” on the date
display.

Changing the Parameters
Use the UP and DOWN arrow keys to move though the
displays to the parameter to be changed. Push the ENTER
key to start the editing process. The first parameter will
flash. Use the UP and DOWN arrow keys to adjust the
parameter to the desired value and press the ENTER key to
save the value. The ne xt parameter will now flash. Repeat
the process until each parameter is properly configured.
Engine Exerciser Display
TheEngineExerciserDisplayshowsthestatusofthe
engine exerciser. When the unit is shipped from the factory
the programmable engine exerciser is “Disabled” and must
be set to “Enabled” by the customer. When the engine
exerciser is running, this display will count down the
remaining time until the end of the exercise period.
Run Time Display
The Run Time Display shows the run time for the engine
exerciser. The default setting from the factory is 30
minutes.
Time Display
The Time Display shows the present system time. The
format is “hours:minutes:seconds”.
NOTE: During total power outages, power to the accessory
is maintainedby a battery in the Controller(see page 4–2 of
Operator’s Manual). Be sure that the 9–volt alkaline
battery is fresh andenabled (jumperin ON position) sothat
the time and date settings are not lost.
Date Display
The Date Display shows the present system date. The
format is “day of week (week) month/day of month/year”.
NOTE: Week is either week 1 or week 2. This is used in
conjunction with the bi–weekly timer.
Daylight Savings Time Adjust Display
This display shows whether the automatic daylight saving
time adjustment is active. The factory default is “NO”. If
enabled, the unit will automatically adjust for daylight
saving time at 2 AM on the first Sunday of April and the last
Sunday of October.
Fast / Slow Adjust Display
This display shows the automatic fast/slow adjustment
value.Thefactorydefaultis0.Thisfeaturecanbeusedto
trim a clock that runs fast or slow. Forexample, if your clock
runs 10 seconds slow per week, change the fast/slow adjust
value to “+10” and the unit will automatically add 10
seconds to the clock every week.
NOTE: Adjustments are made Sunday morning at 2 AM. If
you want your exerciser period to start at 2 AM on Sunday,
you cannot use this feature and the adjustment must be set
to 0.
