J. CLEANING THE MODULE
To clean the outside surface, use a damp
cloth or sponge. Do not use solvents or
abrasive cleaners, and do not open the
enclosure while it is wet (it is an electrical
device).
L. FUSE REPLACEMENT
The fuse on the power supply board (item 7
on the internal layout drawing) is a 1600-mA,
250-V. Use no other type of fuse or the MZA
could be damaged or fail to perform properly.
A spare fuse is provided and positioned on
the mother board item 4.
K. STORAGE AND HANDLING
OF SENSING CABLE
M. NOTE ON CABLE
CLEANING
Despite their rugged construction, TraceTek
sensing cables must be handled in a
manner appropriate for a sensing device
or they may be damaged and require
replacement. Therefore, you should follow
some basic rules for storing and handling all
TraceTek sensing cables:
• Store spare cable in its original container
in a clean, dry place until ready for
installation.
• Schedule cable and probe/sensor
installation after all mechanical, plumbing,
and electrical work has been completed.
• Clean the area where the cable is to be
installed, and remove any obvious debris
or other sources of contamination.
• Do not solder or weld near the cable
without providing protection from heat,
solder flux, or weld splatter.
•
Do not drop tools or floor tiles on the
cable; sharp and heavy objects may
damage the cable.
• Avoid walking or stepping on the cable.
Provide shielding (for example, a half
shell of plastic pipe) where additional
protection is necessary.
• Do not use tape to secure sensing cable
(some tapes and adhesives absorb
moisture) or use solvents that could
eventually cause an alarm.
• Do not drag sensing cable through
contaminants (such as pipe dope, PVC
cement, solvents, oil, or dirt).
TraceTek TT1000 and TT3000 use a solid
core polymer construction and can usually
be easily cleaned with tap water. In extreme
cases or when large amounts of cable are
contaminated, either cable can be washed
in an ordinary dishwasher. Try a water only
(no detergent) cycle first and avoid the
heated dry cycle. When placing the cable in
the dishwasher be sure to tightly connect
the male connector on one end to the
female connector on the other. Keep water
out of the connectors.
TT5000 and TT5001 cannot be cleaned
without special equipment. These cables
normally require replacement after
exposure to fuel or solvent.
N. PERIODIC MAINTENANCE
AND TESTING
Recommended Interval:
Perform a
functional check per the following procedure
at 6-month intervals. Repair or replace all
damaged wiring and senor cables. There are
no field repair procedures for the MZA panel.
If the module fails to perform the functional
tests it must be replaced
