Product Manual A

5. Startup and Configuration PCC 1.1 7-2018

The following information applies to C70 N6, C80 N6, and C100 N6 generator set

models only: Adaptive learn is an engine ECM function that allows the generator set

to "learn" its environment. There are small differences in the performance of each

engine and fuel system component, so the ECM uses inputs from the engine

sensors to adjust running conditions to operate more consistently for each individual

generator set. After installation is complete and while testing the overall system

function, the generator set must be run with no active faults under load (that is,

transfer switch connected to maximum customer load available) until the engine

temperature reaches 80 °C (175 °F) to allow the adaptive learn function to initialize.

The generator set is shipped from the factory with the proper level of engine oil and

coolant, but each should be checked before the generator set is started. Start and

operate the generator set following all the instructions and precautions in the

Operator Manual. Ensure that the bonding bolts are installed into the service panels

before leaving the site.

NOTICE

Before leaving the site, if the generator set is ready to be placed in service,

put the generator set in Auto mode to provide automatic standby power.

NOTICE

Contact your local Cummins service representative if you encounter a fault

code.

5.7 InPower Service Tool

The InPower

service tool can be used in troubleshooting to perform tests, verify

control inputs and outputs, and test protective functions. Refer to the InPower

User's Guide, provided with the InPower software for test procedures.

5.8 Disabling the AMF Feature

NOTICE

This procedure must be performed by a qualified technician.

On single-phase units, the control is shipped with the Automatic Mains Failure

(AMF) feature enabled. This feature has logic to control the RA Automatic Transfer

Switch (ATS), including a 5-minute retransfer to utility delay. If you are not using an

RA ATS, you can eliminate the 5-minute retransfer to utility delay by disabling the

AMF feature using the instructions below.

NOTICE

This procedure is optional. If you do not disable the AMF feature, the

generator set will just run for an additional 5 minutes after the utility has

been restored.
