Figure 3–1. Tramp Metal Detector Front Panel
The TMD has two modes of operation: Run mode and Setup/Calibrate
mode. When the TMD is in Run mode, the NORMAL LED is lit, the
display shows the word COUNT, and the counter shows the total count
of detected tramp.
If the TMD trips (detects tramp), the ALARM LED lights, the display
shows what caused the trip (METAL or LONG BAR), and the counter
shows the coast count, which is the number of pieces of tramp detected
since the system tripped (or while the belt was “coasting” to a stop), if
any.
When the TMD is in Run mode, you can display all setup and
calibration variables but you cannot change them.
Setup/Calibrate mode allows you to make changes to the device setup
and calibrate the TMD for specific metal. In Setup/Calibrate mode, both
the BYPASS and CALIB LEDS are lit. The display indicates which
variable is shown in the counter; the counter shows the current value of
that variable.
The operator interface is based on a menu structure that guides you
through TMD setup and calibration. The menu structure has five “high-
level” menus, shown in the eight-character alphanumeric display, that
indicate the operating mode and status of the TMD.
