PLUG AS-DRAIN 1526144 - Caterpillar

The RAPTOR product is an integrated, digitally compensated control valve and actuator system for regulating and metering the flow of gaseous fuels. The device is designed to accept a fuel rate demand signal. It also incorporates feedback sensors which monitor fuel pressure and temperature, and valve pressure differential. Based on the signal inputs, the device modulates the valve opening to produce a physical fuel mass flow which closely matches the flow demand level.The device is intended to be mounted on or very close to the engine. The dominant application of these valves is gas fueled reciprocating engines provided with an electronic engine control system. Throughout the remainder of the manual, the RAPTOR valve and actuator system will be referred to simply as the RAPTOR valve.Connections to the RAPTOR Valve
The RAPTOR valve has the following connections to the ECM (Engine Control Module), and the engine harness:Earth Ground - Provided through ground lug on housing.Power Input - 18-32 Vdc measured at the RAPTOR valve.Key Switch input - Contact input to switch the RAPTOR valve ON and OFF.CAN bus - Primary demand input.PWM input - Secondary demand input.CAN ID inputs - RAPTOR number selection for CAN bus IDs.CAN termination - Internal CAN termination resistor option.CAN bus out - Second set of CAN pins for connecting to the next CAN device.The RAPTOR valve has one service port for program upgrades by qualified service personnel.
