Honeywell XNX-BT Series Technical Manual

XNX Universal Transmitter
Installation and Operation
50
The transmitter provides a 4-20mA output reecting the input
received. It also offers diagnostic information or data via HART
or any of the additional communication options offered.
Read the Wiring the Transmitter section which denes the
transmitter power and 4-20mA output connections that are
common to all personalities.
Caution: Do not force the POD into the enclosure. Doing so may result in damage to
the wiring or the POD or may alter the switch settings. If resistance is felt, wires may
be preventing the POD from being properly positioned.
CAUTION
!
Searchpoint Optima Plus/Searchline Excel Connections
Connections from the Searchpoint Optima Plus or Searchline
Excel to the transmitter are made via two pluggable terminal
blocks (see the IR personality board wiring guide). Maintain an
8-inch service length of wiring.
In remote mount congurations, the maximum distance between
the transmitter and Optima Plus or Excel is 100 feet (33 meters)
using 0.75 mm
2
(18 AWG) wire minimum.
Note: A second, black-handled screwdriver is included for use on terminal blocks
2 and 4. This tool is smaller than the magnetic wand and is designed to fit into the
terminal connections on TB2 and TB4.
NOTE
!
The Searchpoint Optima Plus or Searchline Excel can be
supplied in either Sink or Source mode operation and is typically
labeled on the white wire exiting the Searchpoint Optima Plus or
Searchline Excel. Use the table in the IR personality board wiring
guide to set S3 and S4 to the same output type that appears on
the wire tag of the IR device.
For more information see the Searchpoint Optima Plus Operating
Instructions (2108M0905) or the Searchline Excel Technical
Manual (2104M0506).
Connecting Generic mA Devices
Use the following schematics to set switches S3 and S4 They
must be set to the same output type (which appears on the wire
tag of the mA device).
The IR personality type provides for a generic mA input under
sensor type conguration. The XNX
®
Universal Transmitter can
be used to convert the mA input to be transmitted over HART
®
or
optional Modbus
®
or FOUNDATION
™
Fieldbus protocols and to
set optional relays (if equipped). Additional conguration of gas
type and unit ID for reporting is required (see the Gas Selection
section). For Generic mA devices, input values below 3mA will
generate Fault 155.
