Chapter 2. Installation
2.7.3 Wiring the Modbus/Service Port
The XMT1000 flow transmitter is equipped with a Modbus communication port for either a connection to PanaView
TM
Plus (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 12 on page 13 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.
2.7.4 Wiring HART or Foundation Fieldbus Connection (if applicable)
The XMT1000 flow transmitters has the option for an additional 4-20mA/HART output or a Foundation Fieldbus output
on terminal block #1 (TB1) per Figure 12 on page 13. In the HART system an active signal is used, whereas FF
corresponds to a passive signal. Connections to this output may be made with standard twisted-pair wiring, but the
current loop impedance for this circuit must not exceed 600 ohms.
To wire the HART or Foundation Fieldbus outputs complete the following steps:
1. Disconnect the main power to the unit and remove the wiring cover.
2. Install the required cable gland in the chosen conduit hole on the side of the electronics enclosure.
3. Refer to Figure 12 on page 13 for the location of the terminal block and wire the HART or Foundation Fieldbus
output as shown. Secure the cable gland.
4. If wiring of the unit has been completed, reinstall the wiring cover on the enclosure and tighten the set screw.
2.7.5 Wiring Analog I/O Terminal Block (if applicable)
The XMT1000 flow transmitters has the option for additional analog outputs, analog inputs, and RTD inputs on
terminal block #2 (TB2) per Figure 12 on page 13. Connections to this output may be made with standard
twisted-pair wiring.
To wire the HART or Foundation Fieldbus outputs, complete the following steps:
1. Disconnect the main power to the unit and remove the wiring cover.
2. Install the required cable gland in the chosen conduit hole on the side of the electronics enclosure.
3. Refer to Figure 12 on page 13 for the location of the terminal block and wire the additional I/O output as shown
along with the table below.
4. Secure the cable gland.
WARNING! Make sure all covers, with their o-ring seals, are installed and the set screws tightened
before applying power in a hazardous environment.
Attention European Customers!To meet CE Marking requirements, all cables must be installed as
