Common Alarm Relay (Option)

Alarms relating to generator and engine performance
appear on the controller and in the Mobile Link™
application (if used). The controller is equipped with a
common alarm relay that provides contacts for an
optional customer-supplied external alarm indicator.
The common alarm relay is normally open until an alarm
occurs, triggering the relay to close the contacts.
Terminals for the common alarm relay are provided in the
wiring harness near the controller plug (Wires 209 and
210).
Contact rating is for resistive load only:

Automatic Voltage Regulator
(AVR) Cooling Fans
The system is equipped with two fans to cool the AVR
electronics. The primary fan is powered by AC during
operation. The secondary fan is powered by 12 VDC
through the controller. The fans are monitored during
operation and if a failure occurs, an alarm is displayed.
The secondary fan continues to operate for up to one
hour after the generator is shut down. Proper cooling
must occur before removing either battery connections or
7.5 amp fuse for maintenance or other service activity.
WARNING
Moving Parts. Avoid AVR fan housing for 80
minutes after generator shutdown. Fan
operates even if fuse is removed. Rotating fan
blades could result in death or serious injury.
NOTE: The AVR cooling air inlet includes a filter. Verify
the filter is installed and properly seated at time the unit is
installed. Check the filter at regular maintenance intervals
to verify proper airflow. Refer to the Owner's Manual.

Battery Requirements

12 volts, Group 26R-540CCA minimum, or Group

WARNING
•
(Group 26R batteries only): Fill the battery with
the proper electrolyte fluid if necessary.
•
Fully charge the battery before installing it.
Before installing and connecting the battery, complete the
following steps:
1. Verify that the generator is OFF.
2. Disengage all connected loads.
3. Remove the 7.5A fuse from the generator control
panel.
Battery cables were factory connected at the generator.
See Figure 6-2. Connect cables to battery posts as
follows:
WARNING
Explosion. Batteries emit explosive gases.
Always connect positive battery cable first to
avoid spark. Failure to do so could result in
death or serious injury.
4. Connect the red battery cable (A: from starter
contactor) to the battery post indicated by a
positive: POS or (+). Torque to 70 in-lbs (8 Nm).
5. Connect the black battery cable (B: from frame
ground) to the battery post indicated by a negative:
NEG, or (-). Torque to 70 in-lbs (8 Nm).
6. Install the red battery post cover (shipped with
loose parts).
NOTE: Dielectric grease should be used on battery
posts to aid in the prevention of corrosion.
NOTE: Damage will result if battery connections are
made in reverse.
