LN Series Free Programmable LN-PRGxxx-12 Controllers Installation Instructions 1
Applications
The LN Series Free Programmable LN-PRGxxx-12
Controllers are microprocessor-based and designed to
control various building automation systems, such as
multi-zone air handing units, lighting control, central
plant applications, and power measurement
applications.
The LN Free Programmable Controllers are built on a
similar platform, but have different numbers of inputs
and outputs. The LN PRG6x0-12 controllers are
compatible with the LN Input/Output (I/O) Extension
Module 400 Series models. For more information on
LN I/O Extension Modules, refer to LN Series Input/
Output(I/O)ExtensionModulesInstallationInstructions
(LIT-12011693).
The LN Free Programmable Controllers use the
LONWORKS® communication protocol.
Follow these recommendations for proper installation
and subsequent operation of each controller:
• Inspect the controller for shipping damages. Do not
install damaged controllers.
• Keep the controller at room temperature for at least
24 hours prior to installation to allow any
condensation that may have accumulated during
shipping to evaporate.
• If the controller is used in a manner not specified
by Johnson Controls, the functionality and the
protection provided by the controller may become
impaired.
• Record the 12-digit Neuron® ID located on either
end of the device (shown on the sticker below the
barcode) for commissioning.
Note: The controller’s plastic enclosure has a
back plate that is separate from the front plate
allowing the back plates to be shipped directly to
the installation site while all the engineering is done
elsewhere.

Mounting
Location Considerations
Observe these guidelines when mounting an LN Free
Programmable Controller:
• Allow for proper clearance around the controller’s
enclosure, wiring terminals, and service pin to
provide easy access for hardware configuration
and maintenance.
• Ensure proper ventilation of each controller and
avoid areas where corroding, deteriorating, or
explosive vapors, fumes, or gases may be present.
• Orient each controller with the ventilation slots and
power supply/output terminal block connector
towards the top to permit proper heat dissipation.
• Do not mount the controller on surfaces prone to
vibration, such as duct work, or in areas where
electromagnetic emissions from other devices or
wiring can interfere with controller communication.
You can mount each controller on a DIN rail, on a wall,
or in a panel. The controllers are equipped with two
mounting holes 0.25 x 0.165 in. (6.35 x 4.191 mm).
DIN Rail
To mount the controller on a DIN rail:
1. Ensure the DIN rail is properly mounted on the
wall.
2. Clip the controller onto the DIN rail.
Wall Mount
To mount the controller on a wall:
1. Press on the side clips to separate the controller’s
front and back plates.
2. Use the holes on the back plate to mark the wall
location.
3. Drill the holes.
Clean the surface and mount the controller using the
appropriate screws.
Wiring
Follow these wiring recommendations:
• Remove the front plate from the back plate to
facilitate in the wiring process. Use a small flat
screwdriver to tighten the terminal connector
screws once the wires are inserted.
• Keep power cables apart from other types of wiring
to avoid ambient noise transmission to other wires
(for example, for power, 3-wire voltage, and current
inputs and outputs).
• Use wires or flat cables ranging from 22 to 14 AWG
(0.644 to 1.630 mm diameter) per pole. Power
cables must remain between 18 to 14 AWG
(1.024 to 1.630 mm) diameter.
• Do not connect the universal inputs, analog/digital
outputs or common terminals to earth or chassis
ground unless otherwise stated.
• Keep all wires away from high speed data
transmission cables (for example, Ethernet cable).
• Keep input and output wires in conduits, trays, or
close to the building frame whenever possible.
!
CAUTION: Risk of Electric Shock.
Disconnect the power supply before
making electrical connections to avoid
electric shock.

LN Series Free Programmable LN-PRGxxx-12 Controllers Installation Instructions4
Power Wiring
We recommend wiring only one controller per 24 VAC
transformer. When only one transformer is available,
determine the maximum number of controllers that can
be supplied using the following method for calculating
the required power transformer capacity:
1. Add up the maximum power consumption of all
controllers, including external loads, and multiply
this sum by 1.3.
2. If the resulting number is higher than 100 VA, use
multiple transformers.
Use an external fuse on the 24 VAC/DC side
(secondary side) of the transformer to protect all
controllers against power link spikes (Figure 3 and
Figure 4).
Note: Connecting the power source to an electrical
system ground is not a requirement for proper system
operation. However, it is a good installation practice in
order to maintain the same potential between all
controllers and Protective Earth.
Configuration Jumper Location and
Identification
Controllers have the following onsite configurable
jumpers.
IMPORTANT: Voltage: 24 VAC/DC; +15%, Class 2.
This is a Class 2 Product. Use a Class 2 transformer
only (rated at 100 VA or less at 24 VAC) to power the
controller.
IMPORTANT: Maintain consistent polarity when
you connect the controllers and devices to the
transformer.
Figure 3: Power Wiring - DC
Figure 4: Power Wiring - AC
IMPORTANT: Connect the COM terminal of each
controller and each peripheral to the same terminal
on the secondary side of the transformer. One
terminal on the secondary side of the transformer
must be connected to the building’s ground. Failure
to maintain consistent polarity throughout the entire
network will result in a short circuit and damage to
the controller.
IMPORTANT: The COM terminals of the controller
are internally wired to the 24 V COM terminal of the
power supply. Connecting a peripheral or another
controller to the same transformer without
maintaining polarity between these devices will
cause a short circuit.

Input Wiring
The controllers have physical connections for inputs,
which are software configurable from within the
device’s Graphical Programming Interface (GPI) LN
plug-in, the LN plug-in when using LN Builder, or the
LN wizard when using the BSC Workbench. Each input
can be configured for digital, resistive, current, or
voltage signals. You must configure the input types
properly in the software plug-in or wizard to ensure
proper input readings.
Note: For wire length less than 75 feet (23 m), use
either a shielded or unshielded 18 AWG wire.
Note: For a wire up to 200 feet (61 m) long, a shielded
18 AWG wire is recommended.
Note: The wire should be shielded on the controller
side and the shield length should be kept as short as
possible.
Wiring Digital Inputs
Use this input configuration to monitor digital dry
contacts, as well as pulsed contacts.
Wiring Resistive Inputs
Use this input configuration to monitor Resistance
Temperature Detectors (RTD); thermistors, such as
1,000 ohm RTDs to 10k ohm Type II and Type III
thermistors; and potentiometers, such as 10k ohm and
100k ohm.
Wiring Current Inputs
Current inputs have a range of 0 to 20 mA. Depending
on the transducer power requirements, you may use
any of the following input configurations. Use Figure 12
for the 2-wire, 0 to 20 mA transducer powered by the
controller’s internal 15 VDC power supply.
Use the Figure 13 configuration for a 2-wire, 0 to 20
mA transducer powered by an external 24 AC/DC
power supply.

Use the Figure 14 configuration for a 3-wire, 0 to 20
mA transducer powered by an external 24 AC/DC
power supply.
Use the Figure 15 configuration for a transducer
powered by its own power source.
For the LN-PRG300-12, LN-PRG4x0-12, and
LN-PRG6x0-12 controllers, it is not necessary to
connect a 249 ohm resistor at the input as this resistor
is built-in to the controller. For these models, configure
the input jumper as follows. For jumper location, see
Configuration Jumper Location and Identification.
Wiring Voltage Inputs
Voltage inputs have a range of 0 to 10 VDC or
0 to 5 VDC. Connect the voltage input according to
Figure 17 if you are using a 3-wire 0 to 10 V or 0 to 5 V
transducer.
Connect the voltage input according to Figure 18 if the
transducer is powered by its own power source.
Wiring Pulse Inputs
The input must be wired according to the requirements
of the connected pulse meter (for example, fast pulse
or slow pulse and internal or external supply type). See
Table 1.
Configure the Pulse Input Types in the software to
verify the pulse meter is powered correctly (set the
Internal/External Supply Type).
Connect the pulse input according to Figure 19 for a
pulse meter that can pull down a +5 VDC supply with a
10k ohm pull-up resistor (internal supply type).
When you use a pulse meter that requires more than
5 VDC to operate, you must use a Fast Pulse Input
type (Table 1). An external power supply is required to
operate the pulse meter. You may use the controller’s
built-in power supply as shown in Figure 20 or use an
external power source (from 6 VDC to 27 VDC
maximum — see Figure 21).

LN Series Communicating Sensors Wiring
The LN Communicating Sensors (LN-SVSEN-0 and
LN-SVSENH-0) are communicating room temperature
sensors with backlit displays and graphical menus.
Connect the LN-SVSENx-0 Sensor to the SUBNET
PORT modular connector of the controller with a
standard Category 5e Ethernet patch cable fitted with
RJ-45 connectors.
If you make your own patch cable, use category 5e
crimped with RJ-45 connectors either T568A or T568B.
Patch cable fitted with connectors supplied by Johnson
Controls are wired as T568B.
For more information on network topology and length,
cable type, setting the Subnet ID and more, refer to the
LN Series Communicating Sensors Installation
Instructions (LIT-12011795) and the LONWORKS
LN-Series Network Communication and Interface
Guide Technical Bulletin (LIT-12011253).
Output Wiring
Each controller has physical connections for digital
(triac) or universal outputs, depending on type and
model. These outputs are all software configurable.
Table 3 shows the controller outputs.
For jumper location, see Configuration Jumper
Location and Identification.
Note: Before you connect output equipment to the
controller, refer to the installation instructions from the
equipment manufacturer.
IMPORTANT: Do not crimp one connector as
T568A and the other connector as T568B on the
same cable.

Output Wiring Recommendations
Output wiring recommendations include:
• For a wire length less than 75 feet (23 m) long, use
either a shielded or unshielded 18 AWG wire.
• For a wire length up to 200 feet (61 m) long, use a
shielded 18 AWG wire.
• The shield of the wire should be grounded on the
controller side and the shield length should be kept
as short as possible.
Wiring Digital Outputs (DOx)
Digital outputs are all made of triacs and there is not
voltage present on the output terminals. Therefore, you
must add an external power source, typically 24 VAC.
Note: To measure the state of a triac output, an
external load must be connected.
If a 24 VAC relay is being controlled, connect it to a
digital output according to Figure 24 or Figure 25,
ensuring that the transformer’s secondary wiring is
grounded as shown.
If a floating actuator is being controlled, connect the
digital output according to Figure 26.
Wiring Universal Outputs (UOx)
You can configure universal outputs to provide either a
discrete signal of 0 or 12 VDC, a linear signal ranging
from 0 to 10 VDC, or a 0 to 20 mA signal
(LN-PRG300-12, LN-PRG4x0-12 and LN-PRG6x0-12
only). The discrete signal can be used to generate a
pulse wave modulation (PWM) signal or a simple
two-state signal. These outputs are protected by an
auto-reset fuse.
Wiring Discrete Outputs
If a 12 VDC relay is being controlled, connect it to a
universal output according to Figure 27.
Wiring Current Outputs
The 0 to 20 mA signal is configurable by jumper
(available for LN-PRG300-12, LN-PRG4x0-12, and
LN-PRG6x0-12 only; for jumper location, see
Configuration Jumper Location and Identification).

Connect the 0 to 10 VDC as shown in Figure 29.
If you are controlling an analog actuator, connect the 0
to 10 VDC output, along with an external 24 VAC
power source, to the analog actuator (Figure 30).
Communications Wiring
The recommended cable type for LONWORKS®
communications is 22 AWG (0.65 mm), twisted pair,
unshielded wire. The LONWORKS communication wire
is polarity insensitive and can be laid out in a bus, star,
or free topology. For loop topology, take special care to
maintain the polarity when connecting the LONWORKS
network to avoid a short circuit.
Note: We recommend you use the bus topology
network configuration for all LONWORKS
communication wiring. This configuration allows you to
troubleshoot the network easily.
Connect both wires to the LON1 or LON2 terminals of
the controller. When you insert multiple wires into the
terminals, ensure you properly twist the wires together
prior to inserting them into the terminal connectors.
For information and detailed explanations on network
topology and wire length restrictions, refer to the
LONWORKS LN-Series Network Communication and
Interface Guide Technical Bulletin (LIT-12011253).
You can also refer to the Echelon® Junction Box and
Wiring Guideline for Twisted Pair LONWORKS Networks
(Part No. 005-0023-01).
Selecting Network Terminators
Two network terminators are required for the bus
topology network configuration. Place one network
terminator at each end of the bus topology channel.
One network terminator is required for the free
topology network configuration. You can put the
network terminator anywhere on the channel.
When used with an LN Series Communicating Sensor,
the network can be accessed at the sensor’s audio
plug port when the two Net to Subnet Port Settings
jumpers inside the LN-PRG Series controller are set to
Enable (for jumper location, see Configuration Jumper
Location and Identification). This connects the main
LONWORKS network to the LN-SVSENx-0 subnetwork
Cat 5e cable to create a free topology LONWORKS
network with maximum allowable total length of all
segments combined to be no more than 1,600 feet
(500 meters). The Cat 5e cable length may also be
restricted by the maximum allowable subnetwork bus
length.
This setup mixes the cable gauge used for the network,
which under rare conditions my cause communication
problems. To help avoid these problems, carefully test
for good communication on the entire network. If there
are any network problems, see Troubleshooting.

IMPORTANT: Use the proper network terminators
for the network topology. Failure to use the correct
network terminators may result in communication
errors between controllers. Do not use multiple
gauges of cable on the same communication bus.

Wireless Installation
The LN PRG Series controller can receive input signals
from wireless devices when connected to a wireless
receiver and programmed with GPI software.
Compatible wireless devices include temperature
sensors, duct sensors, window and door contacts, and
light switches. These devices are easy to install, and
can be mounted on a wide range of building materials.
For information on selecting mounting locations for the
LN Series wireless option controllers, refer to the LN
Series Wireless Solution Guide Technical Bulletin
(LIT-12011628).
Mounting the Wireless Receiver
There are three mounting options: on a wall or ceiling
with double-sided tape, on a wall or ceiling with
mounting screws, or on a metal enclosure using a
1/2-inch National Pipe Thread (NPT) hub.
Regardless of the mounting method, the wireless
receiver should be 16 inches (41 cm) or more away
from the controller or any other network cables.
Wall or Ceiling Mount with Double-Sided Tape
To mount on a wall using double-sided tape, first apply
the tape to the back of the receiver and then stick the
receiver onto the desired wall or ceiling location.
Wall or Ceiling Mount with Screws
To mount the wireless receiver with screws:
1. Separate the front and back plates on the receiver
to open it.
2. Use the mounting holes on the back plate to mark
the wall or ceiling location.
3. Drill the holes.
4. Clean the holes, insert wall anchors, and fasten the
back plate with the screws.
Metal Enclosure Mount
To mount onto a metal enclosure:
1. Affix the 1/2 inch NPT hub to the bottom of the

Maintenance
Each controller requires minimal maintenance, but it is
important to:
• clean the outside of the front plate and the inside of
the back plate with a dry cloth.
• verify the tension of all wires and cables each time
you service the controller.
Disposal
The Waste Electrical and Electronic Equipment
(WEEE) Directive sets regulations for the recycling and
disposal of products. The WEEE 2002/96/EG Directive
applies to stand-alone products that can function on
their own and are not a part of another system or piece
of equipment. For this reason, Johnson Controls®
products are exempt from the WEEE Directive.
Nevertheless, they are marked with the WEEE symbol,
indicating the devices are not disposed with municipal
waste.
Dispose of products at the end of their useful life
according to local regulations and the WEEE Directive.
Troubleshooting
Table 5 describes some troubleshooting scenarios.

électrique.
Table 5: Troubleshooting (Part 1 of 3)
Problem Solution
Controller is powered but does not turn on.
Fuse Is Blown Disconnect power from the controller and check the fuse integrity. Reconnect
power.
Power Supply Polarity Verify that consistent polarity is maintained between all controllers and the
transformer. Ensure that the COM terminal of each controller is connected to the
same terminal on the secondary side of the transformer. See Figure 4 and
Figure 3.
Controller cannot communicate on the LONWORKS network.
Absent or Incorrect Supply Voltage 1. Check power supply voltage between 24 VAC/DC ±15% and COM pins, and
ensure that it is between acceptable limits.
2. Check for tripped fuse or circuit breaker.
Overloaded Power Transformer Verify the transformer is powerful enough to supply all controllers.
Network Not Wired Properly Check that the wire connections are correct.
Absent or Incorrect Network Termination Check the network terminations.
Controller communicates well over a short network but does not communicate on large network.
Network Length Check that the total wire length does not exceed the specifications of the Junction
Box and Wiring Guideline for Twisted Pair LONWORKS Networks.
Wire Type Check that the wire type agrees with the specification of the LONWORKS LN-
Series Network Communications and Interface Guide Technical Bulletin (LIT-
1201253) or Junction Box and Wiring Guideline for Twisted Pair LONWORKS
Networks.
Network Wiring Problem Check that the wire connections are correct.
Absent or Incorrect Network Termination Check the termination(s). Incorrect or broken termination(s) make the
communication integrity dependent upon a controller's position on the network.
Extra Capacitance Ensure no extra capacitance is connected to the network other than the standard
FTT circuit, and a maximum of a 3 meter stub (in bus topology).
Number of Devices on Network Segment
Exceeded The number of controllers on a channel should never exceed 64. Use a router or a repeater in accordance with LONWORKS LN-Series Network Communications
and Interface Guide Technical Bulletin (LIT-1201253) or Junction Box and
Wiring Guideline for Twisted Pair LONWORKS Networks.

Network Traffic Query node statistic to check errors.
Use a LONWORKS protocol analyzer to check network traffic.
I/O Extension Module cannot communicate on the subnetwork
Absent or incorrect supply voltage 1. Check power supply voltage between 24 VAC +15% and COM pins and
ensure it is within acceptable limits.
2. Check for tripped fuse or circuit breaker.
Overloaded Power Transformer Verify the transformer is powerful enough to supply all controllers.
Network Not Wired Properly Check that the wire connections are correct.
Absent or Incorrect Network Termination Check the network termination(s). Only the last LN-IOE4x0 must have the EOL
termination set to ON. When one or more LN-SVSENx-0 sensors are connected
to the controller, only the last LN-SVSENx-0 sensor must have its EOL
termination set to ON. Refer to the LN Series I/O Extension Modules
Installation Instructions (LIT-12011693).
There is another controller with the same
Subnet ID on the subnetwork. Each I/O Extension Module on the subnetwork must have a unique Subnet ID. Look at the Subnet ID DIP switch on the faceplate of each I/O Extension Module.
Network length Check that the total wire length does not exceed the specifications of the
LONWORKS LN-Series Network Communication and Interface Guide
Technical Bulletin (LIT-12011253).
Wire type Check that the total wire type agrees with the specification of the LONWORKS
LN-Series Network Communication and Interface Guide Technical
Bulletin (LIT-12011253).
Hardware input is not reading the correct value.
Input Wiring Problem Check that the wiring is correct according to this manual and according to the
peripheral device's manufacturer.
Open Circuit or Short Circuit Using a voltmeter, check the voltage on the input terminal. A short circuit has a
0 V value and an open circuit has a 5 V value.
Configuration Problem Check the configuration of the input using the controller configuration plug-in or
wizard. Refer to the online help for more information.
Over Voltage or Over Current at an Input An over voltage or over current at one input can affect the reading of other inputs.
Observe the allowed voltage/current range limits for all inputs.
Hardware output is not operating correctly.
Fuse has blown (auto reset fuse) Disconnect the power and outputs terminals. Then wait a few seconds to allow
the auto-reset fuse to cool down. Check the power supply and the output wiring if
necessary.
Output Wiring Problem Check that the wiring is correct according to this manual and according to the
peripheral device's manufacturer.
Configuration Problem Using the controller configuration wizard (LN-GPI), check the configuration of the
input. Refer to the controller's user guide for more information.
0 to 10 V Output, 24 VAC Powered
Actuator is Not Moving Check the polarity of the 24 VAC power supply connected to the actuator while connected to the controller. Reverse the 24 VAC wire if necessary.
Wireless devices not working correctly.
Device not associated to controller Using the device configuration wizard, check the configuration of the input.
Power discharge Recharge the device with light (if solar powered) or replace the battery.
Ensure sufficient light intensity (200lx for 4 hours per day)
Device too far from the Wireless
Receiver Reposition the device to be within the range of the Wireless Receiver. For information on typical transmission ranges, refer to the LN Series Wireless
Solution Technical Bulletin (LIT-12011628).
