Table 3–2. Fault Messages
This section guides you through the initial setup and calibration of your
Oretronic III TMD. Once the TMD is set up correctly, few or no
changes to the settings are required.
Before you begin setting up and calibrating the TMD for your
application, be sure that:
• The TMD has been installed both mechanically and electrically in
accordance with the procedures in Chapter 2: Installing the TMD
and the installation and field wiring drawings.
• You are familiar with the functions of all the keys, indicators, and
displays on the TMD front panel.
• You have taken the required measurements (refer to Section
“Determining Values to Use for Initial Setup”).
• You have a timing mark on your conveyor belt.
• You have a piece of tramp metal the average size to be detected.
• You power up the system 15 minutes before beginning setup.
