BOARD GP 3747689 - Caterpillar

Configurable Parameters
The system configuration parameters must be programmed when the application is installed. Program parameters before the initial engine start-up. Incorrect programming of parameters may lead to complaints about performance and/or to engine damage.Data from a gas analysis is required for determining the correct settings for the fuel quality and for the specific gravity of the gas. The data must be entered into the Caterpillar Software, LERW4485, "Gas Engine Rating Pro (GERP)".
