7 Additional Troubleshooting

If the paralleling system does not operate as expected, check the items in the following charts. Verify that both
generator controllers have blue circuit boards. Section 4 also includes some troubleshooting tips for problems that
may arise during the initial setup.
Breaker will not
close in RUN.
Check whether the other
generator set is connected to the
paralleling bus.
NO
Check whether the generator sees
bus voltage (L2-L3 in SiteTech)
above 25% of rated voltage.
NO
Bus sensing is not connected or is
connected incorrectly.
Check wiring between both
generators and the Automatic
Paralleling Module.

SiteTech indicates that both
engines are under load, but the
ATS has not transferred.
Transfer ATS and start each
generator individually. Does the
metering read positive power with
load on the generator?
NO
The metering on this generator is
backwards.

re-determine CT direction.
Both generators are

load indicated in SiteTech
must be due to electrical
noise. Continue to
commission the system.
