electronics. Fuse type is Littlefuse Nanofuse2 0454005.MR, part number
58105674.
Replacing battery
Inside the electronics (MELS 5208) is a CR2032 type 3 V lithium battery that
powers the real time clock while power is off. When battery is empty, the clock
resets to January 1, 2010. Empty battery can also corrupt counter statistics. Typical
battery life time is over ten years.
The interference level too
high
Used frequency not suitable for the
operating environment
Change operating frequency
(Additional reduction of interference
level can be achieved by lowering the
HI SPEED value)
Interference source located too close
to detector
(Video monitors, radio equipment,
powerful electric motors, AC power
cables, thyristor control circuits etc.)
Move interference source or detector
Large moving metal object too close to
the WTMD
Increase distance between detector
and metal object
Floor vibrating when people walk
through the unit
Improve support of the floor or move
the detector
DANGER
Replace fuse only with equivalent type to avoid risk of fire.
