Auto start modules

Model: AECM105

User Manual

The Model AECM105 is a new generation of AECM designed to automatically / remotely and manually start and stop the engine either by using wired remote start input (so called 2 wire start) or via optional devices: 24/7 digital timer, wireless key fob(s) or/and Battery Voltage Sensor. The wireless key fob control allows to start and stop the engine remotely within approximately 100 m distance (1000 m distance is optional). The actual working distance depends on many factors and could be much less than 100 m for instance if the key fob is used inside the building. The Battery Voltage Sensor (BVS) controls the engine starting battery voltage (or external battery bank) and able to start the engine automatically upon registering Low Voltage Threshold 11.8Vdc (23.6V) This LVT can be re-adjusted by customer on-site. It will continue to run the engine until the engine starting battery becomes fully charged at 13.8Vdc (27.6V).The BVS will then register High Voltage Threshold and shut down the engine. This HVT can be also re-adjusted by customer on-site.
AECM105 will indicate the operational status and fault conditions, automatically shut down the engine and indicate the start engine failure by flashing "START FAIL" LED on the front panel. Other faults are indicated by steady LED. Remote wired operation of the module is via single pole normally open maintained switch connected between terminal #5 (wire 1) and battery negative terminal #13 (wire GR/Y). The switch is shown on wiring diagram as "RST".. Read more...
