Ramsey Oretronic IV Tramp Metal Detector REC 4479C
Page 36
The TMD IV operator interface is based on a tree-structure of menus that the user navigates using the soft-
keys. From the Run screen, there are 5 lower-level menus that can be accessed through the soft-keys:
•
The View menu, which provides visibility to alarms, system settings, system options, and if the
password protection option is enabled, a place to log in.
•
The Calibration menu (“Calib”), which provides access to lower
-level menus for calibrating (balancing)
the coils and, if clip detection is enabled, the clip sensitivity. This menu also offers a screen for testing
tramp detection without tripping alarms (and shutting down the belt).
•
The Options menu, which allows the user to enable or disable all of the TMD IV optional settings.
•
The Settings menu, where values can be assigned to the programmable features of the TMD IV.
•
A Service menu, intended for field support functions, such as software upgrades or reset to factory
defaults.
Front Panel LEDs
A single row of indicator LEDs is arranged across the top of the LCD display.
The NORMAL LED (green) indicates that the TMD IV is in normal Run mode, has not determined a fault or error
exists, and has not detected metal since the RESET (bell) key was pressed. It is never on when the ALARM LED
is on.
The ALARM LED (red) indicates that metal was detected and the TMD IV has not been reset since the
detection. This LED will also be on if a fault or error is present. It is never on when the NORMAL LED is on.
The BYPASS LED (yellow) indicates that the alarm output relay is disabled
Alarm output is also disabled (and the BYPASS LED lit) when the TMD IV is in Calibrate mode. This allows you to
set up and calibrate the detector without generating alarms during the process.
BYPASS disables the alarm even if metal is detected and essentially isolates the TMD IV from the rest of the
system.
The CALIB LED (red) indicates that the TMD IV is in Setup/Calibrate mode. When it is lit, you can change setup
variables or calibrate the detector.
Keypad
The TMD IV
has a membrane keypad that’s designed to be rugged, long
-lasting, and easy to use even in
conditions that require gloves. In normal operation, the only key used is the Reset key, also called the Alarm
key, represented by a bell symbol on the keypad. For convenience in operation, an external Reset key is
environmentally isolated and mounted on the outside of the enclosure.
The function of the soft-keys along the bottom of the LCD depends on the current screen. The function of the
soft-keys is explained further in the following sections
The remaining keys (Home and digits 0-9) are used during calibration or when changing system settings.
Pressing the Home key from any one of the sub-menus will return the system immediately to the Run screen.
The digit keys are self-explanatory;
however the “2” and “8” keys can also be used to navigate through the
menus (as an alternative for the up-arrow and down-arrow soft keys).
