Maintenance and Troubleshooting
This section provides information about TMD IV maintenance and troubleshooting. It includes pointers for
routine maintenance and suggestions for diagnosing operational problems.
The maintenance information in this section should be sufficient to meet your service needs. If you encounter
a problem that requires technical assistance, please call your service representative (refer to Service, Repair
and Replacement Parts section of this manual for contact information).
Overview
You can expect the TMD IV system to operate satisfactorily and hold its calibration for months with simple
routine maintenance.
Routine Maintenance
Keep the area around the TMD IV free from rocks and material build-up.
The TMD IV system can be washed down with water and meets NEMA Type 4 and IP66
(P/N 147797, 147800)
standards. Do not add harsh chemicals, caustics, or disinfectants to the wash down solution.
The control unit enclosure can be wiped clean with a damp cloth, and if necessary, a mild detergent. Never use
abrasive cleaners, especially on the display windows. Keep the enclosure door tightly closed to prevent dirt
infiltration.
As a preventive measure, check all wires, plugs, and integrated circuits in the control unit to make sure they
are tight in their connectors.
The idlers on each side of the TMD IV
coil support structure should be greased according to the manufacturer’s
specifications.
Make sure that the conveyor belt is running true to the conveyor centerline in the detection area to prevent
damage to the coil support structure and coil(s).
Troubleshooting
If your TMD IV is not detecting reliably or your calibrations are providing unexpected results, there are several
things you can do to determine the cause of the problem.
Always begin with a visual inspection, not only of TMD IV components but also of the conveyor belt, the idlers,
and all optional equipment.
If your system operates but is not working as expected, there are adjustments you can make to the TMD IV
device setup and calibration settings to make it work better. First, you must determine what is causing the
problem and what you can do to correct it.
