1 LN Series Communicating Sensors LN-SVSEN-0, LN-SVSENH-0 Code No. LIT Issued November 2017 Application Refer to the QuickLIT website for the most up-to-date version of this document. 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 (Figure 1). 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. Figure 1: Leaf Icon 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 ). LN Series Communicating Sensors 1

3 Installation For proper installation and subsequent operation of the LN Series Communicating Sensors, follow these recommendations: Inspect the sensors for shipping damages. 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. 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.

5 Setup and Adjustments Supported Quantity of Sensors Per Controller LN VAV/VVT and LN-PRGxxx-12 controllers support between 4 and 12 LN Communicating Sensors. See Table 1 for the maximum allowable sensors per controller. You must set the Subnet ID of all sensors within the address range listed in Table 1. Table 1: Number of LN Communicating Sensors Controller Models Support Controller Series Maximum Number of Sensors Subnet ID Address Range LN-VAV/VVT LN-PRG LN-PRG LN-PRG4x LN-PRG6x 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 Figure 4. 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 ).

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 Figure 7). 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 Figure 8). 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 Figure 9). LN-IOE4x0-0 I/O Extension Modules and LN-SVSENx-0 sensors EOL switches are factory-set to OFF by default. 7

8 Setting the LN Communicating Sensor Subnet ID You can commission the LN-VAVCF-12 Controller with an LN-SVSENx-0 Sensor. 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 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.

10 Setting the LAN Type Set the BAC/LON jumper to LON. Figure 10: BAC/LON Jumper Set to the LON (LONWORKS) Position LONWORKS Network Access from the Sensor The LONWORKS network is optionally available from the LN-SVSENx-0 sensor audio plug port. To connect the main LONWORKS network to the LN-SVSENx-0 sensor subnetwork Cat 5e cable, set the two Net to Subnet Port Settings jumpers inside the LN-PRG series controller to Enable (Figure 11). Figure 11: Net to Subnet Port Settings Jumpers This setting creates a free topology LONWORKS network with a maximum total length of all segments to be no more than 500 meters (1,600 feet). The Cat 5e cable length may also be restricted by the maximum allowable subnetwork bus length (see Subnetwork Bus Total Length). 10

12 Troubleshooting Table 3: Troubleshooting the LN-SVSENx-0 Sensor LN-SVSENx-0 Sensor screen is blank and backlight is off Problem Solution Is the LN-SVSENx-0 sensor connected to the controller? Is power being supplied to the controller? Is the cable connected to the controller and LN-SVSENx-0 sensor? Error Code Interpretation Table 4: LN-SVSENx-0 Sensor Error Code Interpretation Error Code Possible Cause Solution Verify that the LN-SVSENx-0 sensor is connected to the controller and that the patch cables are plugged in to the connectors. See Installation. There may be no power being supplied from the controller. Check if the controller has power or if the controller s internal fuses have blown or tripped. Verify wiring. Was the patch cable made onsite? Verify that the RJ-45 crimp connectors are installed on the cable correctly. See Connection Cable. LN-SVSENx-0 Sensor screen is blank and backlight is on for 30 to 45 seconds Normal Operation Firm upgrade in progress Wait for the upgrade to complete. Do not disconnect the LN-SVSENx-0 sensor from the controller as the upgrade will restart once it is reconnected. Device not communicating with controller Is the address correctly set to a unique address? Is the device too far from the controller? Is there a configuration problem? Have the subnetwork EOL settings been set correctly? Clock icon flashing for 15 seconds After 15 seconds: flashing error code 1 with Bell icon Flashing error code 2 with Bell icon Flashing error code 3 with Bell icon Each LN-SVSENx-0 sensor must be set to a unique address for each controller. See Setting the LN Communicating Sensor Subnet ID. Verify the distance between the device and the controller. See Figure 4. With the LN-GPI program, check the configuration of the sensor; for example, is it enabled? You must configure the device properly in the software plug-in or wizard. Only the last LN-SVSENx-0 sensor must have its EOL termination set to ON. See Figure 7 and Figure 8. When one or more LN-IOE4x0-0 I/O Modules are connected to the controller, only the last LN-IOE4x0-0 must have its EOL termination set to ON. See Figure 9. Cannot communicate with controller. Invalid configuration. LN-SVSENx-0 sensor is not properly configured in the controller. Wait for the communication link to the controller to be established. Verify wiring. Verify that all LN-SVSENx-0 sensor Subnet IDs are unique to this controller. See Setting the LN Communicating Sensor Subnet ID. In the LN-GPI program, re-synchronize the code with the controller. Contact Johnson Controls support. With the Graphical Programming Interface program, check the configuration of the sensor; for example, is it enabled? Refer to the GPI Help for more information. 12
