Vehicle Ignition Monitoring

When Auto-On is disabled (see below) and the ignition input wire is connected, the Thor VM1 monitors the ignition input signal
and adjusts modes as described below.

Auto On Behavior

The Thor VM1 can be configured for Auto-On using the
For information on the Ignition input signal please see the power cable instructions in the Thor VM1 Vehicle Mounting
Reference Guide.

Auto-On Enabled

Note: When Auto-On is enabled, the Ignition Input signal, if connected via the Thor VM1 vehicle power
supply cable, is ignored.
When Auto-On is enabled, the Thor VM1 boots when external power is applied, such as when:
The Thor VM1 is placed in a powered Smart Dock, with the dock's power switch set to On.
l
The Thor VM1 is in a Smart Dock and truck power is applied to the dock
l
The Thor VM1 is in a powered Smart Dock and the dock's power switch is turned from Off to On.
l
If the Thor VM1 is already on and one of the above events occurs, the Thor VM1 continues to run, however the power
management scheme may change based on the connection to external power.

Auto-On Disabled

Note: When Auto-On is disabled, the Ignition Input signal, if connected via the Thor VM1 vehicle power
supply cable, is monitored.
If the Thor VM1 is Off and Ignition Input is Inactive, the Thor VM1 remains Off.
If the Thor VM1 is Off and Ignition Input changes from Inactive to Active, the Thor VM1 boots.
If the Thor VM1 is On and Ignition Input changes from Inactive to Active, the Thor VM1 remains On. If, for example, a Thor
VM1 is running on the UPS and is placed into a Dock connected to a truck when the truck ignition is On, the power
management scheme may change based on the availability of external power.
If the Thor VM1 is On and Ignition Input changes from Active to Inactive, this event is treated the same as a Power button
press, which places the Thor VM1 in Suspend.
If Auto-On is disabled and the Ignition Input wire is not connected, the Thor VM1 only powers on when the Power button is
pressed.
