Backup Battery; Fuse; Power Management Modes - Honeywell THOR VM1 User Manual

• The UPS battery is not charged when the internal Thor VM1 temperature is below 0°C (32°F). This corresponds to
an ambient (room) temperature of approximately -10°C (-14°F).
• The UPS battery is not charged when the internal Thor VM1 temperature is above 45°C (113°F). This corresponds
to an ambient (room) temperature of approximately 35°C (95°F).
• If the UPS battery cannot be charged due to a temperature extreme, the
the Thor VM1 to a different location to charge the UPS battery.
When the Thor VM1 is operated in an environment where the UPS battery is not able to charge due to temperature
extremes, the Thor VM1 should be removed to a location within the safe charging temperature range during off hours.
A discharged UPS battery cannot protect against data loss in the event vehicle power is interrupted.
Charging Timeout
• A fully discharged UPS battery normally recharges in less than 4 hours when the Thor VM1 is in a powered dock and
within the safe charging temperature range.
• If the UPS battery is not charged before an 8 hour (or 4 hours for some earlier software revisions) timeout period
expires, the UPS Status LED
• The charge timeout is reset if charging resumes upon application of external power.
• The charge timeout is reset if charging resumes when the Thor VM1 enters the permissible temperature range for
charging.
• If the charge timeout occurs, remove the Thor VM1 from the dock and
the Thor VM1 in the dock and power on.
Charging and Power Management
• Charging of the UPS battery continues when the Thor VM1 is in power management (display off, suspend or
hibernate modes).

Backup Battery

The Thor VM1 has a permanent Lithium battery installed to maintain time, date and CMOS setup information for a minimum
of 90 days. The lithium battery is not user serviceable and should last five years with normal use before it requires replace-
ment.
Note: The backup battery should only be changed by authorized service personnel.

Power Management Modes

The Thor VM1 has four power modes: Full On, Standby, Hibernate and Off.
Full On Mode
When the Thor VM1 is attached to either vehicle power or an external power supply or is operating from the UPS bat-
tery and the power button is pressed, the Thor VM1 is in the On mode. In this mode, the keypad, touch screen and any
attached peripherals such as a scanner function normally. The display remains on until the display, standby or hiber-
nate timer (if enabled) expires.
When in Full On mode, the status LED is solid green.
(page 3-12) is amber.
The Thor VM1 uses an 8A time delay (slow blow) fuse that is externally accessible and user
replaceable. The fuse is located on the back of the dock. The fuse is accessed by unscrewing
the cap as indicated.
Should it need replacement, replace with same size, rating and type of fuse:
• Littelfuse 0215008.MXP
• Cooper Bussmann BK1/S506-8-R
• Bel Fuse 5HT 8-R
or equivalent.
Fuse has voltage on it even when power is off. Always disconnect input power before changing
the fuse.
