Idle control and charge protect for select Fords
InPower’s SAT-MD-C Auxiliary Load Programmable Controller provided charging and high idle engine RPM control for the Ford 2020+ Transit vehicles directly. Since the 2020+ Ford Transit incorporates an advanced intelligent charging system for increased fuel economy (See Ford Transit Documentation), the SAT-MD-C can request increases in power output
as needed from the alternator for charging batteries, or running auxiliary loads. The example integration of the SAT-MD-C is shown below in the System Diagram. The functions of this unit are programmable at the Factory for custom applications. This document shows an example which can be customized.
The SAT-MD-C also provides high idle control, both for operating equipment with a fixed idle (RPM1), but also a state of charge based RPM2 that is variable based on Battery Voltage for a charge based variable RPM.
In this example, the Battery Voltage Based RPM2 works as follows: a lower Battery Voltage results in an increase of the engine RPM; Likewise an increase in Battery Voltage will result in a decrease in Engine RPM as the Battery charges the has a blunt cut wires for direct connect to available wiring.
The Optional Fixed RPM Input is available for more conventional high
Idle applications where a fixed RPM is required. This Fixed High Idle RPM setting is enabled by SW1 (tying it to +12V). The set-point for the Fixed RPM can be adjusted by SW3: connecting to +12V to raise RPM; connecting to GND to lower RPM; disconnecting from either voltage stores the last RPM as the new value.
