Source Availability Signal Contacts
The module provides one Form C contact each for the
normal and emergency sources signal the acceptability of
the source as sensed by the controller. The signal contacts
operate in conjunction with the Source Available lights on
the operator interface. Field wiring terminals are
provided as shown in Figure 5–3 and the wiring diagram.
Contact ratings:
2 amps @ 30 Vdc, 0.5 amp. @ 125 Vac resistive
Programmable Engine–Generator Exerciser
The module includes a programmable engine exerciser
that provides for weekly or biweekly operation. This
optional exercise timer may have to be turned on
(enabled) by setting the S1 DIP switch actuator 7 to OFF
(left position), and S2 DIP switch actuator 5 to OFF (left
position).
A backup battery in the controller (see page 4–2 and page
5–3) must be turned on to maintain the settings and to
allow programming with the normal and emergency
power turned off (page 5–1).
The programmable engine exerciser incorporates a 7–day
or 14–day time base. Proper 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).
See next page for instructions on setting the timer.
