Honda EXXXXXIS Series requires a GSCM-mini-i

The Generator Start Control Module-mini (GSCM-mini) is a non-programmable micro-processor based generator start controller that is designed to auto start and stop gas or propane generators.

It supports three types of 3 or 4 wire gas-generator control:  momentary, maintained or key ignition.  It automatically disconnects the starter when a minimum generator AC Hz output is measured.  It has a fixed crank time and over and under frequency shut down.  The GSCM-mini is powered by 12 volts DC from the generator battery and can monitor the battery voltage and start the generator to charge its own battery.  The GSCM-mini uses the generator AC output to know when the generator has stated and is running.  GSCM-mini-o has a 30 second crank rather than a 20 second crank to allow for glow plugs. 

The GSCM-mini is also available in a mini diesel version, inverter version or a programmable version. 

Europe, Australia & Japan please see GSCM-mini-50Hz.

Dimensions:  W: 3.2” x  H: 1.2" x  D: .875"

    I installed the mini and the genset started and stopped as stated. A person by the name of Abner was a great help in helping me to understand the wiring of it to my system. I am thankful for this persons understanding of the product and his thorough knowledge of how to wire it. He is a great credit to your company and I will recommend this product. Ron Barrowcliffe

    Excellent product. I used it to auto start an Onan 7.5 marine diesel genset with an Outback Power FN-DC battery monitoring system. Very good documentation. It's encapsulated in epoxy and seems very durable.
