Battery Replacement

WARNING! EXPLOSION HAZARD! The enclosure cover and the transparent
plastic barrier must be fitted when the unit is situated in a hazardous area and
may not be removed unless the area is known to be non-hazardous.
Two 3.6 V Lithium type batteries (size D) are required to power the SKF Multilog WVT
when on battery power. Battery type XL-205F 19Ahr from XENO is recommended. The
batteries cannot be recharged. The SKF Multilog WVT contains a battery "gas gauge"
that is read by the controlling application to allow the charge remaining to be
monitored.
WARNING! The battery level reading resets to 100% after the batteries are
removed from the holder.
You can check the battery level of the SKF Multilog WVT in the WDM user interface by
going to Device Vendor Parameters > Device Power > Battery Level.
WARNING! Failure to follow these battery safety instructions may result in risk
of fire, electric shock or electrocution, or damage to the unit.
To replace the batteries:
• In a non-hazardous area, remove the cover from the SKF Multilog WVT unit.
• Flip power switch PWR to the EXT position.
• Unscrew the thumbscrews on the battery holder and remove the battery holder.
• Replace the batteries with a fresh set, ensuring that the polarity matches the
markings on the holder.
IMPORTANT: Always use fresh batteries. Do not mix new and old batteries.
• Re-insert the holder and tighten the thumbscrews.

WARNING! The WDM web page permits you to
enable routing on a battery powered device, but
doing so causes the battery level calculation to be
inaccurate. Enabling routing will produce an
irreversible error in the battery level calculation
until the batteries are replaced with a new pair.
