LN Series LN-VSTAT and LN-PSTAT Sensors Installation Instructions

3.
Connect the SMRT+ and SMRT- output terminals
of the LN-VSTAT to the SMRT+ and SMRT- input
terminals on the LN-VAV/VVT controller (Figure 6).
Using the LN-VSTAT as a Portable Device
You can use the LN-VSTAT sensors as a portable
device to perform VAV balancing. If an LN-Sensor is
already connected to the VAV that you intend to
balance, directly connect the LN-VSTAT to the
communication jack within the LN Series Sensor.
Note:
Terminals 1 and 2 of the right most terminal
block within the LN Sensor must be connected to the
SMRT+ and SMRT- inputs of the VAV controller before
you can use the communication jack. Typically, these
connections should have been made when the VAV
controller and LN Sensor were first installed.
To connect the LN-VSTAT sensors to an LN-Sensor
using an 1/8 in. mono or stereo audio cable:
1.
Use the taps on the bottom of the sensor to remove
the sensor face plate.
2.
Connect the SMRT+ and SMRT- output terminals
of the LN-VSTAT sensors to two wires that
terminate in the 1/8 in. audio plug (Figure 7).
3.
Remove the LN Sensor faceplate and insert the 1/8
in. audio plug into the communication jack. Ensure
the two output terminals on the right side of the
LN-Sensor are wired to the SMRT+ and SMRT-
terminals of the LN-Sensor (Figure 8).
