CLAMP-V BAND 1760113 - Caterpillar

Configuration Parameters
Table 1 is a list of the parameters that can be configured for G3500E Engines. The parameters are described below. The parameters are programmed into the Electronic Control Module (ECM) via the Caterpillar Electronic Technician (Cat ET). The values of the parameters can be viewed on the "Configuration" screen of Cat ET.

(1) This parameter applies to engines that are equipped with software that supports a remote input for fuel quality.
(2) This parameter applies to engines that are equipped with software that supports impending shutdowns.Timing Control
The "Desired Timing" parameters allow the customer to program the timing of the ignition spark in order to meet the needs for specific applications. The desired timing value can be changed while the engine is running or while the engine is stopped. The value that is entered for the desired timing is the ignition timing when the engine is operating at rated speed and at full load.Note: The actual ignition timing at a given instance may vary from the desired timing value. This variance is due to variations in the engine speed, engine load, or the detonation level.The range for programming the desired timing is 0 to 40 degrees before the top dead center (TDC) position."First Desired Timing"
The "First Desired Timing" is determined with the methane number of the primary fuel that is used. Use the Engine Performance Sheet, "Fuel Usage Guide". The ECM selects the "First Desired Timing" when terminal P1-20 is an open circuit."Second Desired Timing"
The "Second Desired Timing" is determined with the methane number of the alternate fuel that is used and the Engine Performance Sheet, "Fuel Usage Guide". When this input is connected to the digital return or to the − Battery, the engine control will use the "Second Desired Timing". If an alternate fuel is not used, enter the same timing that was entered in the "First Desired Timing".Air/Fuel Ratio Control
Before the initial start-up, a current gas analysis is required. Periodic gas analyses are also recommended. Data from the gas analysis must be entered into Caterpillar Software, LERW4485, "Gas Engine Rating Pro (GERP)". The
