The default Power Scheme selected for the Thor VM2 depends on:
•the Power Configuration Mode (page
•if external power is connected to the Thor VM2,
•and, for ignition control, the status of the vehicle ignition signal.
The Power Schemes are defined below. The active Power Scheme depends on the
•AC/DC - When AC/DC has been selected for the Power Configuration mode, this Power Scheme is selected. Because of the presence of external power, this Power Scheme has longer timeout values.
•Ignition Control/Ignition On - When either Ignition Control option has been selected for the Power Configuration mode and the Ignition Switch is On, this Power Scheme is selected. Because of the presence of external power, this Power Scheme has longer timeout values.
•Ignition Control/Ignition Off - When either Ignition Control option has been selected for the Power Configuration mode and the Ignition Switch is Off, this Power Scheme is selected. This Power Scheme has shorter timeout values (compared to Ignition On) to preserve the vehicle battery.
•
•UPS - When any Power Configuration Mode is selected but no external power is present, the UPS Power Scheme is used. This Power Scheme has much shorter timeout values designed to shut down the Thor VM2 before the UPS battery is depleted.
Because of the cumulative effect, if the Thor VM2 is operating from the UPS, for example:
•The backlight turns off after 30 seconds of no activity,
•The display turns off after 1 minute and 30 seconds of no activity (30 sec + 1 min),
•The Thor VM2 enters Suspend after 11 minutes and 30 seconds of no activity.
•The Thor VM2 shuts down after 31 minutes and 30 seconds of no activity.
•If the User Idle timer is set to Never, the power scheme timers never place the Thor VM2 in User Idle, System Idle or Suspend modes.
