Ramsey Oretronic IV Tramp Metal Detector REC 4479C

Features and Options
The TMD IV includes a number of standard features and available options that enhance its performance in a
conveyor system.
Simplified Operator Interface
The LCD panel and membrane keypad make it easy to enter and change values and to scroll through the
displays. The display indicates tramp count and coast count during normal operations and is used during setup
and calibration.
LEDs visible from outside the enclosure indicate SETUP, ALARM, NORMAL, and BYPASS conditions, and a bar
graph displays signal strength (see Figure 1-9).

Increased Detection Sensitivity
With the increase in sensitivity, the TMD IV can detect similar sized tramp at higher belt speeds than its
predecessor, or smaller tramp at the same belt speed.
Field Upgradeable Software
System updates can be installed by qualified Thermo Fisher Scientific field engineers and representatives in
just a few moments, without removing or re-installing the controller.
Modbus Interface
An RS-485 interface allows the user to communicate with the controller using a standard Modbus terminal or
mobile device. Through this interface, virtually all of the major operational characteristics of the controller can
be read and, in many cases written.
Synchronization of Transmitter Pulses
When two or more detectors are within 30 feet of each other, the SYNC input feature allows for the
synchronization of transmitter pulses. This prevents the detectors from mistaking a transmitter pulse from
another detector for a metal signal.
