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) Extension Modules Installation Instructions

(LIT-12011693).

The LN Free Programmable Controllers use the

ONWORKS® 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.

Installation

Observe these guidelines when installing an LN Free

Programmable Controller:

• Transport the controller in the original container to

minimize vibration and shock damage.

• Verify that all parts shipped with the controller.

• Do not drop the controller or subject it to physical

shock.

IMPORTANT: Prevent any static electric discharge

to the controller. Static discharge can damage the

controller and void the warranties.

Industry Canada Statement

The term IC before the certification/registration

number only signifies that the Industry Canada

technical specifications were met.

Le terme « IC » précédant le numéro d'accréditation/

inscription signifie simplement que le produit est

conforme aux spécifications techniques d'Industry

Canada.

This equipment has been tested and found to

comply with the limits for a Class A digital device

pursuant to Part 15 of the FCC Rules. These limits

are designed to provide reasonable protection

against harmful interference when this equipment is

operated in a commercial environment. This

equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in

accordance with the instruction manual, may cause

harmful interference to radio communications.

Operation of this equipment in a residential area

may cause harmful interference, in which case the

users will be required to correct the interference at

their own expense.

Mounting Wiring 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.

Power Wiring 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. 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.

Input Wiring Wiring Resistive Inputs 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.

Use the Figure 14 configuration for a 3-wire, 0 to 20 mA transducer powered by an external 24 AC/DC power supply. Connect the voltage input according to Figure 18 if the transducer is powered by its own power source. Figure 18: Voltage Input – Transducer with Its Own Power Source Figure 14: Current Input – 3-Wire Transducer, Externally Powered Use the Figure 15 configuration for a transducer powered by its own power source.

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).

If a floating actuator is being controlled, connect the digital output according to Figure 26. 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.

Voltage Outputs Connect the 0 to 10 VDC as shown in Figure 29. 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).

Subnetwork Communications Wiring with the LN-PRG6x0-12 Controller Supported Quantity of Sensors Per Controller The LN-PRGxxx-12 controllers support between 4 and 12 LN Communicating Sensors. See Table 4 for the maximum allowable sensors per controller. You must set the Subnet ID of all sensors within the address range listed in Table 4.

Connecting the Wireless Receiver Connecting to the Controller Wireless Port Connect the wireless receiver to the controller with the included telephone cable (4P4C modular connectors). Locate the telephone socket inside the device (Figure 34). The wireless-option controllers have a wireless port where you connect the telephone cable. Locate the wireless port on the bottom of the controller.

Maintenance ! • CAUTION: Risk of Electric Shock. Disconnect the power supply before making any electrical connections to avoid electric shock. MISE EN GARDE : Risque de décharge électrique. Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge électrique. 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.
