Cummins PCC 2100 via Hardwired I/O (V3)
This topic is the install guide for the after-market gateway (part# A0009887841) with A0009887772 (GL899-PARTIAL RETROFIT HARNESS) when utilizing Cummins PCC 2100 PowerCommand® control systems with hardwired connections.
PowerCommand Control (PCC) 2100 HMI
2100 Control Board - TB1 location
Connections are based on default configurations for Out1/K1 programmed as Common Warning, Out2/K2 as Common Shutdown, and Out3/K3 as Not In Auto.
Equipment Connection Details
Generac Gateway Side Terminations | Description | Harness Wire Color | Equipment Side Terminations |
|---|---|---|---|
2 | DC+ | Red | TB1-17 or TB1-18 |
1 | DC- | Black | TB1-20, 21, or 22 |
6 | Engine Running | Purple | TB1-19 |
7 | Not in Auto | Green | TB1-12 |
Harness Relay #1 | COM | Blue | TB1-1 |
N/O | White / Blue | TB1-20, 21, or 22 |
Note that when using A0009887772 harness, terminal 5 on Generac Gateway is connected to battery negative. Therefore the common terminal on equipment controller Engine Running and Not in Auto signals should be connected to battery positive and the signals should be connected to the terminals mentioned in above table. In other words, this means outputs on equipment controller must source voltage to Generac Gateway inputs.
If the equipment controller outputs are sinking voltage, a 12/ 24 vdc (depending on battery voltage) relay needs to be connected between the controller output (for example, engine running) and common. The relay N/O contact would connect to terminal 6 on Generac Gateway and relay COM connects to battery positive post
