CFGMODELNUM

Possible Causes

• •Different generator types
• •Different generator types.
• •Generators are not the same kW model
• •Generators not yet started in RUN with other generator in OFF.
• •Incorrect configuration of one of the generators
• •Incorrect configuration of one of the generators.
• •Intermittent connections on RBUS network wiring.
• •One of the two generators is incorrectly configured.
• •The system voltage of the two generators intended to be paralleled is not the same.
• •The two generators that are intended to be paralleled have incompatible model numbers
• •Two generators intended to be paralleled have incompatible model numbers.
• •Wires 9A and 9B crossed between the generators.
• •Wires 9A or 9B not connected

Suggested Actions

1. 1Check for crossed wires 9A and 9B between generators.
2. 2Contact an authorized dealer for paralleling system installation, startup, troubleshooting, or service
3. 3Contact an authorized distributor or dealer for paralleling system troubleshooting or service
4. 4Correct the configuration of the generators
5. 5Ensure paralleled generator sets are the same kW model (e.g., two 14 kW, two 20 kW, or two 26 kW models)
6. 6Ensure the system voltage of both generators is the same.
7. 7Ensure wires 9A or 9B are connected.
8. 8Place the other generator in OFF and this generator in RUN to activate auto-discovery.
9. 9See the APM instruction sheet for instructions to perform the auto-discovery procedure.
10. 10The paralleled generator sets must be the same kW model (i.e. two 14 kW or two 20 kW models)
11. 11The paralleled generator sets must be the same kW model. (i.e. two 14 kW or two 20 kW models.)
