LN Series Communicating Sensors Installation Instructions 1 Refer to the QuickLIT website for the most up-to-date version of this document. LN Series Communicating Sensors Installation Instructions LN-SVSEN-0, LN-SVSENH-0 Application The LN Series Communicating Sensors (LN-SVSEN-0 and LN-SVSENH-0) are designed to interface with the LN Series Variable Air Volume controllers (LN-VAVCF-12) and the LN Series Free Programmable Controllers (LN- PRGxxx-12 versions). The two models of LN Communicating Sensors provide precision local temperature sensing, system status information, and a variety of control functions. In addition, the LN-SVSENH-0 model allows you to monitor humidity level. Through the user-friendly interface, you can view and adjust environmental settings. You can view the temperature, adjust the setpoint, and apply occupancy overrides. With the Graphical Programming Interface (GPI) programming tool, you can create display control features that use all the LN Communicating Sensor capabilities. The LN Communicating Sensor capabilities include a Leaf Icon that displays the efficiency of your setpoints. The leaf icon displays one to four leaves (Figure1). Four leaves on the leaf icon denotes that your setpoint is set to the highest energy efficiency, three leaves denotes higher energy efficiency, two leaves denotes moderate energy efficiency, and one leaf denotes low energy efficiency. Also, a five-character alpha numeric display shows messages. The password-protected technician mode allows you to perform commissioning and troubleshooting. Also, you can use the LN Communicating Sensors as a handheld tool to select appropriate controller applications for HVAC equipment to be controlled, to perform air balancing of the system, and for troubleshooting. The LN-SVSEN-0 and LN-SVSENH-0 sensors are also used to configure applications in the LN-VAVCF-12 controller. For information, refer to the LN Series Variable Air Volume (VAV) LN-VAVCF-12 Controller Installation Instructions (LIT-12011802).

Do not install damaged sensors. •Ensure you have proper clearance of the sensor’s casing and two RJ-45 connectors for easy access, hardware configuration, and maintenance. •The controllers are designed to operate under the following conditions: -Ambient temperature from 41 to 104°F (5 to 40°C) -Storage temperature from -4 to 122°F (-20 to 50°C) -Relative humidity from 0 to 90%, noncondensing •Ensure proper ventilation of devices and avoid areas where corroding, deteriorating, or explosive vapors, fumes, or gasses may be present. •Keep the sensor at room temperature for at least 24 hours before installation to allow any condensation that may have accumulate during shipping and storage to evaporate. •Do not drop the sensor or subject it to physical shock. Dimensions IMPORTANT:Work in a static-free area. Discharge any static electricity you may have accumulated by touching a known, securely grounded object. Do not handle the sensor without proper protection against static discharge. Use a wrist strap when handling the sensor. Secure the wrist strap clamp to earth ground.

Note:The LN Communicating Sensors are not designed for outdoor use. Mounting Instructions 1.Remove the security screw from the device (Figure3). 2.Open the device by pressing in the two tabs on the bottom of the device with a flat screwdriver and pulling the bottom side of the front plate out. 3.Pull all cables 6 inches out of the wall, and insert them through the central hole of the back plate. 4.Align the back plate with the wall and mark the location of the mounting holes on the wall. Note:Make sure to orient the proper side of the back plate facing upwards. 5.Remove the back plate and drill holes in the wall if necessary. 6.Install anchors in the wall if necessary. 7.Make sure that the mounting surface is flat and clean. 8.Screw the back plate onto the wall. Do not overtighten. 9.Plug the wire(s) into the connector(s). 10.Gently push excess wiring back into the wall. 11.Reattach the front plate and make sure it clips tightly into place. 12.Install the security screw.

See Table1 for the maximum allowable sensors per controller. You must set the Subnet ID of all sensors within the address range listed in Table1. About the Subnetwork Bus For the LN-SVSENx-0, the subnetwork bus extends the LON trunk to the LN-SVSENx-0 sensor to provide network access for maintenance and troubleshooting. The LN-PRG6x0-12 controllers use the subnetwork bus to support the LN-IOE4x0-0 Series Modules through 2- wire shielded cable. All LN-VAVCF-12 controllers also use the subnetwork bus to support up to four LN-SVSENx-0 sensors using standard structural cabling. For an overview depiction of a subnetwork including LN Communicating Sensors, see Figure4. Subnetwork Bus Total Length The total maximum length of all subnetwork buses, including both the length of the LN-SVSENx-0 sensor subnetwork bus and the LN-IOE4x0-0 subnetwork bus, is 300 m (1,000 ft). The maximum length of the LN-SVSENx-0 subnetwork bus is 200 m (650 ft). The maximum length of the LN- IOE4x0-0 subnetwork bus is 300 m (1,000 ft). For more information on subnetworks, refer to the LN Series Input/Output (I/O) Extension Modules and Communicating Sensors Subnetwork for LN-VAVCF-12 and LN-PRGxxxxxx-12 Application Note (LIT-12011815).

IMPORTANT:If you make your own patch cable, use Category 5e cable and crimp the RJ-45 connector at both ends of the cable either as T568A or T568B.

Patch cables fitted with connectors that Johnson Controls supplies are wired as T568B. Subnetwork Bus Topology and EOL Terminations Only a daisy-chain topology is acceptable for the LN-SVSENx-0 sensor subnetwork bus. T-connections are not allowed. Subnetwork with LN-VAVCF-12 When you install one or more LN-SVSENx-0 sensors with an LN-VAVCF-12 Controller, you must set the EOL terminations of only the last LN-SVSENx-0 sensor to ON. Set all EOL terminations on all other LN-SVSENx-0 sensors to OFF. The controller must be the first devices on the bus, as the EOL termination in these devices are permanently enabled (see Figure7). Subnetwork with LN-IOE4x-0-0 and LN-PRG6x0-12 When you install one or more LN-SVSENx-0 sensors with an LN-PRG6x0-12 Series Controller, set only the EOL terminations of the LN-PRG6x0-12 Series Controller and the last LN-SVSENx-0 sensor to ON. Set all other EOL terminations on the LN-SVSENx-0 sensors to OFF (see Figure8). When you install LN-IOE4x0-0 I/O Extension Module with an LN-PRG6x0-12 Controller and one or more LN- SVSENx-0 sensor, set only the EOL terminations on the last I/O Extension Module and the last LN-SVSENx-0 sensor to ON. Set all other EOL terminations on the I/O Extension Modules and LN-SVSENx-0 sensors to OFF (see Figure9). LN-IOE4x0-0 I/O Extension Modules and LN-SVSENx-0 sensors EOL switches are factory-set to OFF by default.

The default Subnet ID for an LN- SVSENx-0 sensor is 1. To commission an LN-VAVCF-12 controller, set the LN-SVSENx-0 sensor’s Subnet ID to 1. If you set the LN-SVSENx-0 sensor’s Subnet ID to another value (for example, the display flashes error code 1 with the Bell icon when the LN-SVSENx-0 sensor is connected to a controller for commissioning), change the Subnet ID to 1 as follows: 1.Connect an LN-SVSENx-0 sensor to the controller with a Cat 5e patch cable. Wait for the Bell icon and the number 1 to flash on the display. 2.Press and hold the Menu button for 5 seconds to enter the password menu. The display shows 10000. 3.Use the Down button to set the number to 9995 (this is the default password). 4.Use the Menu button to select SUBNET ID. The current controller’s Subnet ID appears. 5.Use the Up and Down buttons to set the controller’s Subnet ID. Note:Press and hold either the Up or Down button to fast-advance the display value. 6.Press the Menu button once. 7.Press and hold the Menu button for 5 seconds to exit the configuration menu. You can now use the LN-SVSENx-0 sensor to go from one LN-VAVCF-12 controller to the next for commissioning purposes.
