Power Source Availability Signal Contacts
ThemoduleprovidesoneFormCcontacteachforthe
normal and emergency power sources to signal the
acceptability of the source as sensed by the controller. The
signal contacts operate in conjunction with the Source

terminals are provided as shown in Figure 5 and the wiring
diagram.
Contact ratings:
2 amps @ 30 Vdc, 0.5 amp. @ 125 Vac resistive

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
in the Series 300 ATS Group 1 Controller
(see Operator’s Manual, Sections 4 and 5) must be turned
on to maintain the settings and to allow programming wi th
the normal and emergency power sources turned off.
TheAcc.11BGmoduleincludesaprogrammablegenera-
tor exerciser that provides for weekly or biweekly opera-
tion. 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–gene rator exerciser incorpo-
rates 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).
