1.5.3 Wiring the Modbus/Service Port

The XMT1000 flow transmitter is equipped with a Modbus communication port for either a connection to Vitality (PC
software) or to a separate control system. The port is an RS485 interface.
IMPORTANT: The maximum cable length for an RS485 connection is 4000 ft (1200 m).
To wire to this RS485 serial port, refer to Figure 6 on page 8 and complete the following steps:
1. Disconnect the main power to the unit and remove the rear cover.
2. Install the required cable gland in the chosen conduit hole on the side of the electronics enclosure.
3. Feed one end of the cable through the conduit hole, and wire it to the terminal block.
4. If wiring of the unit has been completed, reinstall the wiring cover on the enclosure and tighten the set screw.
Note: Prior to use, the serial port must be programmed.
WARNING! Make sure all covers, with their o-ring seals, are installed and the set screws tightened
before applying power in a hazardous environment.
