Ignition Control - Honeywell Thor VM2 Reference Manual

Ignition Control

Ignition wire must be connected and the Ignition Control power mode must be selected. When switched vehicle power is
available the Thor VM2 ignition signal wire can be connected (less than 1mA over input voltage range) to the switched circuit to
allow the Thor VM2 to power on when the vehicle is switched on. When the vehicle is switched off, more aggressive power
management settings are enabled to preserve the vehicle battery charge.
Note: If the vehicle chassis is not a suitable ground, connect the Green wire to the negative terminal (-Vo) of the power
source.
