Note: After setting DIP switches to the generator set
application, be sure to power down and then
power up the controller (disconnect the battery
and then reconnect the battery of the generator
set) or use the prime power switch, if equipped.
The controller will NOT acknowledge the DIP
switch change until after generator set controller
is powered up.
Push down the end of the DIP switch near the OPEN
label to open the switch, or push down the other end to
close it. See Figure 1-10.

set overspeed frequency is set using DIP switch 1.
Select 70 Hz for 60 Hz voltages and 60 Hz for 50 Hz

cooldown cycle or shut down immediately. The choice is
made using DIP switch 2.

Engine Configuration (DIP Switches 4 and 5). See
Figure 1-9 for the DIP switch positions based on engine
configurations regarding non-ECM, MDEC, and J1939
engine communication selections.
Modbusr Address (DIP Switches 6- -8).
Modbusr device requires a unique address. Address
numbers are created using a binary number system with
DIP switches 6--8. Figure 1-11 shows the DIP switch
position for each address number.
