Appendix B - Remote Front Panel
This Appendix describes the optional remote front panel for the
Oretronic III TMD. It includes technical specifications, wiring
procedures, instructions for setup and operation, and a spare parts list.
The operator interface to the TMD is a front panel on the control unit.
The front panel is composed of a touch panel keypad, LED indicators,
an eight-character alphanumeric display, and a three-digit counter LED.
The keypad is used to enter and change values and to scroll the displays.
The displays indicate tramp count and coast count during normal
operations and are used during setup and calibration. LEDs visible from
outside the enclosure indicate NORMAL, BYPASS, and ALARM
conditions and a bar graph show signal strength.
A remote front panel display option using RS-485 serial
communications can be added to the main TMD control unit. The
remote front panel includes a separate power supply and has a distance
limitation of 4,000 ft (1,219 m) from the main TMD control unit.
The remote front panel is identical to the front panel on the control unit
in both appearance and operation.
Keep the area around the TMD free from rocks and material build-up.
The TMD system can be washed down with water and meets NEMA
Type 4X 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 coil support structure should be
greased according to the manufacturer’s specification.
