If, after running this procedure, the clip(s) continue to trip the TMD IV metal alarm, navigate to the Clip Coarse
calibration screen and manually reduce the coarse sensitivity value by 1 (see Figure 2-5). Note that this may
allow some tramp to go undetected if it is small enough and is within the vicinity of a clip.
External Communication
With the installation of the optional RS-485 communication card, the Oretronic IV can communicate with
external systems using the Modbus RTU protocol. Using this interface, alarm status and other data can be
remotely monitored, and the device can be reset.
If this level of control is not needed, it is possible to wire the alarm output and reset switch input directly to
remote devices or panels. Refer the field wiring diagram for the location of the Alarm, Bypass, and Remote
Reset connectors on the CPU board.
