Communications Wiring
Caution:
• Communication wire pairs must be dedicated to MN-Sx (S-Link) and MicroNet
LONWORKS network (LON) communications. They cannot be part of an active, bundled
telephone trunk.
• Shielded cable is not required for S-Link or LON wiring.
• If the cable is installed in areas of high RFI/EMI, the cable must be in conduit.
• If shielded wire is used, the shield must be connected to earth ground at one end only
by a 470K ohm 1/4 watt resistor. Shield must be continuous from one end of the trunk
to the other.
Communications wiring includes a connection between the controller and a TAC I/A Series
MicroNet Sensor via the S-Link and a connection between the controller and the MicroNet
LONWORKS Network (LON). An optional LONWORKS Network connection between the
controller and one TAC I/A Series MicroNet Sensor is also possible.
Sensor Link (S-Link) Wiring
S-Link wiring powers and enables the MN-Sx sensor. The S-Link needs at least 24 gage
(0.51mm), twisted pair, voice grade telephone wire. The capacitance between conductors
cannot be more than 32 pF per foot (0.3m). If shielded cable is used, the capacitance
between any one conductor and the others, connected to the shield, cannot be more than
60 pF per foot (0.3m). Maximum wire length is 200 ft. (61m).
Note:
• Controller supports one TAC I/A Series MicroNet Sensor (MN-Sx).
• S-Link wiring is polarity insensitive.
• If conduit is used between a TAC I/A Series Sensor and a controller, the MicroNet
LONWORKS network and S-Link wiring can be in the same conduit, however, they must
be separate cables.
• S-Link wiring can be in the same conduit with UI, AO, and DI Wiring.
MicroNet LONWORKS Network (LON) Wiring
An approved Category 4 or 5, twisted-pair (two conductors) cable may be used for both
connecting to the MicroNet LONWORKS Network and the optional LONWORKS Network
connection between the controller and MN-Sx sensor. LONWORKS Network wiring is polarity
insensitive.
Caution: Do not mix with UI, AO, DI or DO types of wiring. If conduit is used between a
TAC I/A Series Sensor and a controller, LONWORKS Network wiring and S-Link wiring can
be in the same conduit, however, they must be separate cables.
MN 100, MN 150, and MN 200 controllers use LONWORKS Free Topology Transceiver (FT
3150) and support polarity insensitive bus (daisy-chain) and free (all combinations of star,
tee, and loop) wiring topologies. A maximum of 62 nodes can be connected per segment.
Note: See TAC I/A Series MicroNet System Engineering Guide, F-26507 to design a
MicroNet LONWORKS TP/FT-10 network, including recommended topologies and
approved cable types.
• Use of the LON terminals to connect to the MN-Sx sensor permits use of the
sensor’s built-in LON Jack.
• To preserve the integrity of the network, the LON wiring connecting a TAC I/A Series
MicroNet controller to an MN-Sx sensor must be run to the sensor and back, in
daisy-chain fashion. A wire “spur” must not be used to connect the sensor to the
controller.
• While the MN-Sx sensor is not counted as a “node” in the LonWorks network
(LON), all LON wiring to the sensor must be counted when determining the length
of the FTT wiring segment.

F-26266-7
I/O Wiring
I/O connections include universal inputs, analog outputs, digital inputs, and digital outputs.
See Figure-2, Figure-3, and Figure-4 for proper wire terminal information.
Caution: If shielded cable is used, connect only one end of the shield to earth ground at
controller.
Universal Inputs (UI), Analog Outputs (AO), and Digital Inputs (DI)
Caution:
• Input and output devices cannot share common wiring. Each connected device requires
a separate signal and return conductor.
• Power wiring cannot share conduit with UI, AO, S-Link, LON, or DI wiring.
Note:
• If maximum closed switch voltage is not more than 1.0 V and minimum open switch
voltage is at least 4.5 V, then solid state switches may be used for a UI or a DI.
• UI, AO, DI, and S-Link wiring can share a single conduit.
UI, AO, DI, wiring needs at least 24 gage (0.51mm), twisted pair, voice grade telephone wire.
The capacitance between conductors cannot be more than 32 pF per foot (0.3m). If shielded
cable is used, the capacitance between any one conductor and the others, connected to the
shield, cannot be more than 60 pF per foot (0.3m). Table-1 provides wiring specifications.

Digital Outputs (DO)
Caution:
• DO terminals accept one 16 gage (1.29mm) wire or two 18 gage (1.02mm) wires. The
selected wire gage must be consistent with the load current rating.
• DO wiring cannot be intermixed with DI, UI, S-Link, LON and AO wiring.
• MN 100, MN 150, and MN 200 controllers are Class 2 devices. Each digital output can
support up to 24 Vac/Vdc at 1.0 amp (24 VA) pilot duty.
Note: Digital Output wiring can be intermixed with class 2 power wiring.
Each DO is an isolated Form A (SPST) relay. If the transformer is sized correctly, the 24 Vac
Class 2 Controller power source (Figure-7) may be used for load power.

LONWORKS Network.
None required.
On indicates a possible network connection problem, or a
large amount of network traffic is present.
Remove the LONWORKS Network
connections from the controller
and determine if the LED goes off.
If the LED does not go off, replace
the controller. If the LED does go
off, check the network topology
(connections to each node, routers, terminators, etc.) and the
amount of traffic on the network.

physical location of the controller. If a sensor (MN-Sx) is
connected, its red occupancy LED will flash (1/sec) during
the wink period.
Anytime
On indicates that the neuron application is not running.
Neuron applications are not field replaceable.
Replace the controller.
Blinks (1/sec) to indicate that the neuron application is
loaded, but the neuron’s communication parameters are
not loaded, are being reloaded, or have been corrupted.
Neuron is considered unconfigured. Communication
parameters cannot be configured by field personnel.
Use a third party network management tool to commission the
controller, or use the change state
tool in WorkPlace Tech Tool (version 4.0 or greater) to set the
Neuron® to the configured/on-line
state.
While the controller is unconfigured, WP Tech can be used to
download an application, but at
the completion of the download,
WP Tech versions 4.0 and higher
will restore the Neuron to the
unconfigured state.
Anytime
Off may indicate that the neuron application is loaded but
the device is off-line. In this state, a pre-loaded HVAC
application will not run.
Use a third party network management tool to commission the

Controller Selection
Identical pairs of factory barcode labels are attached to each controller. The labels can be
used to select controllers for application downloading purposes. Each pair of labels contains
a unique Neuron ID. One of the labels remains on the controller permanently; the other label
can be placed on a job site plan.
The Neuron ID may be entered into the WorkPlace Tech Tool. The WorkPlace Tech Tool
(must be version 4.0 or greater) can then download an application to the selected controller.
See WorkPlace Tech Tool 4.0 Users Guide, F-27255, for additional information.
Caution: Do not hold service pin button when selecting a controller. Holding the service
pin button for 6 seconds or longer will completely unconfigure controller. See WorkPlace
Tech Tool 4.0 Engineering Guide, F-27254, for additional information.
The service pin button is also used to select controllers. When this button is pressed, the
controller sends a broadcast message containing its Neuron ID to the online or connected
WorkPlace Tech Tool. After the message is received, the controller can be selected for
application downloading. See WorkPlace Tech Tool 4.0 Users Guide, F-27255, for additional
information.
Service
Components within MN 100, MN 150, and MN 200 controllers cannot be field repaired. If
there is a problem with a controller, follow the steps below before contacting your local
Schneider Electric office.
1. Make sure controllers are connected and communicating to desired devices.
2. Check all sensors and controlled devices are properly connected and responding
correctly.
3. If controller is operating, make sure the correct profile and application is loaded by
checking the LONMARK Program ID and the nvoDeviceInfo using Work PLace Tech Tool.
For more information, see WorkPlace Tech Tool 4.0 Engineering Guide, F-27254.
4. Record precise hardware setup indicating the following:
Version numbers of applications software.
Controller firmware version number.
