Rpm Inputs - THOMSON MEC 310#GENSET CONTROLLER Installation And Operation Manual

Charger alternator connections
This schematic diagram shows the basic way the charger alternator and the MEC 310 can
cooperate.
Only one running feedback is needed, but for optimal safety and function both the RPM (Tacho)
input and the digital running feedback (D+) can be used as in the example below.
