Gas concentrations are read by the XNX from the Searchpoint Optima Plus or
Searchline Excel 4-20mA output. A digital communication connection on TB2
provides an additional confirmation as well as diagnostic information.
Connections from the Searchpoint Optima Plus or Searchline Excel to the XNX
are made via two pluggable terminal blocks allowing ease of installation and
service see Figure 19. HA recommends an 8" (203mm) service length for wiring
be maintained.
Be sure wires for 4-20mA outputs are routed away from sources of noise such as
relay wires 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 Figure 19 to set
S3 and S4 to the complimentary operating state of the equipment.
For more information see the Searchpoint Optima Plus Operating Instructions
(2104M0508) or the Searchline Excel Technical Manual (2104M0506).

Be certain to dress the wires properly to ensure cabling does not contact switches
1-4 on the back of the POD.
Do not force the POD into the enclosure as it may indicate an interference condition
resulting in damage to the wiring, POD or switch settings.
WARNING
Setting of S3 and S4 while power is applied or improperly set prior to applying power
WILL PERMANENTLY DAMAGE the XNX. Both switches must be set in either Source
or Sink prior to applying power.
Do not adjust switch settings while power is applied to the XNX; permanent damage
WILL occur.
