3.0 CABLING AND CONNECTING WIRING

WARNING!
!
Ensure device is disconnected or circuit breaker is open per the requirements of IEC 60947-1 and IEC 60947-3
before opening the opening the transmitter.

Remote Mount Cable Connection to Sensor

The ProComm Max transmitter is designed to connect to a single-port converter box
mounted on meter. See Figure 12 as an example showing the Ultra Mag meter. This design
converts flow data and sends it to the ProComm Max transmitter. All calibration data is
held in non-volatile memory at the converter. Consequently, cable distances from the
converter to the transmitter have no effect on meter calibration. This will allow users to
swap transmitters in the field if needed, requiring only the SD card in the transmitter to be
moved to the replacement unit.
The port on the converter is available as either a cable gland fitting or a quick connect
fitting.

Terminal Block Diagram

All connections are made on the terminal blocks. To access the terminal blocks, loosen the four screws on the front of
the transmitter and open the front panel. Refer to Figure 7 and Figure 8. The example shown below (Figure 13) does not
necessarily represent all transmitter models, however, it shows the placement for all terminal blocks used in all models.
NOTE: The terminal blocks unplug from the circuit board for easy connection.
