WARNING Electrical shock hazard. Disconnect VAC and VDC power supplies before servicing. Failure to do so could result in electric shock or death. IMPORTANT: When working with circuit board components, Bard recommends the use of an anti-static wrist strap to prevent static electricity shorts to electronic controls. LV1000 Controller The LV1000 controller is part of this Bard air conditioning system. It is used to control up to four (4) wall-mount air conditioners from one controller. The microprocessor control provides an easy-to-read interface with large LCD graphical display. It provides control for redundancy for the structure and equal wear on all units. The LV1000 controller is configured for first on/next on sequence. Conduit is recommended for all wiring. Route communication wiring and power supply wiring in their own separate conduits. The LV1000 controller is not weatherproof and is intended for use in weathertight structure. Mounting the LV1000 Controller The dimensions of the LV controller are 16" by 12" by 6". Because the LV1000 controller utilizes a remote temperature sensor as opposed to one located in the controller box, the controller itself can be installed in any indoor location that is suitable, preferably at eye level. Four (4) mounting holes are provided for mounting to the wall and holes for conduit connection are provided in the base, sides and top of the controller. Ground case before doing any work or do not connect power (48VDC) to unit until earth ground is connected. The LV1000 controller includes a fused power supply terminal in the terminal block. Before connecting wires to the terminal block, confirm that the fuse in the fuse holder is in the proper position (active) as shown in Figure 2. FIGURE 2 LV1000 Fused Power Supply Terminal Fuse in Active Position Shipping Position Code: +07U0006EN Manual 2100-673I Page 7 of 45 LV1000 Supply Wiring The LV1000 controller is powered by -48VDC from the shelter. A field-supplied 5 amp DC circuit breaker is required. Field-supplied supply wiring should be minimum 16 gauge, maximum 14 gauge (see Figure 3). A reliable earth ground must be connected in addition to any grounding from conduit. Grounding bolts and nuts are included with the controller for this purpose; a 2 hole grounding lug must be field supplied. Install as shown in Figure 4. Failing to ground the controller box properly could result in damage to the equipment. FIGURE 3 LV1000-300 Controller Supply Wiring The controller requires a separate -48VDC power supply, an additional 5-amp DC breaker (field supplied) and minimum 16 gauge supply wire. -48VDC termination at controller: Bring the -48VDC power supply wires through conduit to the controller box. Land the positive (+) 48VDC wire to terminal #1 and the negative (-) 48VDC wire to terminal #2. NOTE: If the DC wiring is not terminated correctly on the specific polarity-indicated terminals of the block, the controller will not activate and will not function. Verify polarity of connections and wait to initialize controller until "system start up." 123 + 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 4 FIGURE 4 Controller Grounding Posts A reliable earth ground must be connected in addition to any grounding from conduit. Attach earth ground to side of controller box using bolts and nuts supplied with controller and fieldsupplied 2 hole grounding lug. Failing to ground the controller box properly could result in damage to the equipment or personal injury. Manual 2100-673I Page 8 of 45 Code: +07U0006EN Installing Remote Indoor Temperature/Humidity Sensor(s) One remote indoor temperature/humidity sensor and 35' of 18 gauge 5-conductor shielded cable is included with the controller. This sensor must be installed for proper operation. Mount the temperature/humidity sensor in a location least likely to be affected by open doors, rack-mounted fans, radiant heat sources, etc. Location height should be approximately 60" above the floor. The sensor should be installed on a 2" x 4" junction box to allow for control wire conduit (see Figure 5). Use shielded cable to connect to controller. The maximum cable length to connect the temperature/humidity sensor to the LV1000 is 98'. FIGURE 5 Remote Indoor Temperature/Humidity Sensor Installation 1.

Connect the other end of the shielded cable to the sensor terminals. Be sure wires are connected to proper terminals as shown in table above. Sensor jumpers need to be positioned for 0-1 V. With sensor oriented as shown in image to right, move both jumpers to right position (DP1 and DP2 set to OFF). This applies to all indoor temperature/humidity sensors connected to the LC controller. See illustration mounted inside of sensor cover for further detail on jumper position. Earlier versions of this sensor may be mounted in a different orientation which would affect the positioning of the sensor jumpers. See page 37 for additional information on sensor orientation. Code: +07U0006EN Jumper DP1 DP2 Manual 2100-673I Page 9 of 45 For proper operation, the remote indoor temperature/humidity sensor (and any additional sensors) must be configured properly with the controller as shown in Step 2 on page 9. Up to two additional temperature and humidity sensors can be purchased and installed. Alternately, temperature-only sensors can be purchased and installed instead of the combination sensors. All installed sensors must be enabled in the controller menu (see Configure Sensors in system installation instructions included with the wall-mount unit). Use shielded cable to connect additional sensors to controller. FIGURE 6 Additional Remote Temperature and Temperature/Humidity Sensor Installation Up to two additional temperature/humidity sensors may be added. Be sure the sensors are connected to the proper terminals on the terminal block and sensor as listed below. See page 8 for information on correct sensor jumper position.

The processor core type is needed when deciding what software update package to download for the controller. If the OS version line is blank after the numerical version numbers, or has a "Core 0" identifier after the numerical version numbers, then the PLC requires an update package that does not have a _core# suffix or has the _core0 suffix in the software update package. If the OS version line has a "Core 2" identifier after the numerical version numbers, then the PLC requires an update package that has the _core2 suffix in the software update package.

It identifies the processor core type of the PLC and can only be used in a PLC with the corresponding processor core type. (See Software Info section for more information on how to identify processor core type.) Unit Information The LV1000 has the ability to provide individual wall unit information which it displays in individual unit information screens. The purpose of these screens is to eliminate the need to remove the panel from a wall unit in order to plug in the TEC-EYETM. Each unit information menu item displays the following information: unit main status screen mirror, unit A/C circuit information, unit model/serial number, unit last 24 hour run times and component lifetimes. Unit Main Status Screen Mirror The Unit Main Status screen (Figure 18) mirrors the main status screen of the wall unit. The main status screen also shows the return air temperature (RAT), mixed air temperature (MAT), outdoor air temperature (OAT), outdoor air humidity (OAH) and outdoor dew point (ODP) conditions. Blower speed, condenser fan speed, damper position and unit status are also displayed. In addition to what is displayed on the wall unit's main status screen, this screen also displays the actual wall unit output staging. Refer to the latest version of unit service manual 2100-694 for a list of wall-mount unit status messages. FIGURE 18 Unit Main Status Screen Mirror Unit A/C Circuit Information The A/C Circuit Information screen lists all available A/C sensor measurements and calculations on the unit specified (see Figure 19).

Code: +07U0006EN Manual 2100-673I Page 27 of 45 CONTROL OPERATION NOTE: Screenshots shown in this manual reflect default settings (when applicable). Temperature Control Control Value Averaging The system requires one temperature and humidity sensor (included with LV) to operate. It allows a total of three temperature sensors and three humidity sensors to be connected to the LV for better representation of what is happening in the shelter. When more than one sensor is used, the value is averaged and then used for temperature control operations and humidity control operations. Comfort Mode The LV has a feature that allows a temporary override of the temperature control settings. When "comfort mode" is activated, the system will control to 72°F. The system will stay in this mode for 60 minutes and is intended to provide a more comfortable space for a technician during a service call or scheduled maintenance. Emergency Vent When the hydrogen input indicates an alarm, the system will enter emergency vent mode. The LV will communicate to each wall-mount unit that emergency vent mode is active. The wall-mount units will then override the damper position to 100% open and, after a short delay to allow the damper to open, turn the blower on. Emergency vent mode will stay active until the hydrogen detector is no longer in an alarm state. Emergency Cool When the high temperature alarm is activated, the system will enter emergency cool mode. The LV will communicate to each wall-mount unit that emergency cool mode is active. At that point, the units will override any restrictions to the economizer disable and operate the economizers normally, as long as the outdoor temperature is cooler than the indoor temperature. Emergency cool mode will stay active until the high temperature warning is no longer in an alarm state. Cooling When the wall-mount units are connected to the LV, the economizer and compressor are commanded off and on by the LV. This allows the supervisory controller to consider the most effective and efficient order to bring cooling functions on using all of the available equipment installed on the shelter. At the same time, the LV will be able to match the load requirements of the shelter. To adjust the cooling setpoint: 1. Press MENU key to go to the Main Menu screen. 2. Press UP or DOWN keys and ENTER key to enter USER password 2000. Manual 2100-673I Page 28 of 45 3. Press UP or DOWN keys to scroll to Sys Config; press ENTER key. 4.

Press the ESCAPE key several times to return to Main Menu screen. FIGURE 35 Adjusting Setpoints The LV monitors the space temperature and compares the value to the space cooling setpoint. The system will compare how far above or below the space temperature is when compared to the cooling setpoint. The LV will also consider how long the shelter temperature has been above or below the setpoint. Using these two considerations, the controller will generate a cooling demand. The cooling demand is a value between 0 and 100%. 0% represents no cooling demand and 100% representing full cooling demand. The system will consider all of the available cooling stages and distribute the number of stages across the cooling demand range. As the demand rises, the system will stage on equipment every 2 minutes. As the demand lowers, the system will stage off equipment every 2 minutes. The system will stage the equipment on in the order shown in Table 6. Unit Rotation The system is also capable of rotating the order in which the units are brought on. This is done to distribute the equipment run time to each unit. This prevents one unit from providing all of the cooling for the shelter and shorting the lifespan of the wall-mount unit. The system is set to switch the unit rotation order every 7 days from the factory. This timeframe is adjustable.

FIGURE 38 Changing Humidifier Output Direction Manual 2100-673I Page 31 of 45 Dehumidification The system will take several measures to limit the indoor humidity levels when they reach specified setpoints. These measures include passive dehumidification and active dehumidification. Passive Dehumidification Passive dehumidification means that the system will modify normal operation measures to reduce and extract humidity from the space, without generating any extra demand on the system. These measures include limiting the economizer from allowing outdoor humidity into the indoor space, disabling the high sensible blower setting to allow for more latent heat removal and enabling a slower blower speed than nominal, when applicable, to increase the latent heat removal capability. Passive dehumidification turns on when the indoor humidity rises above the passive dehum setpoint and shuts off after the indoor humidity level falls below the dehum off setpoint. Active Dehumidification Active dehumidification means that the system will take extra measures to extract humidity from the indoor space. Active dehumidification will work with passive dehumidification but will use one unit that is capable to heat and cool the space in a cycle with reduced blower speeds to extract the most moisture from the indoor room. Active dehumidification turns on when the indoor humidity rises above the active dehum setpoint and shuts off after the indoor humidity level falls below the dehum off setpoint. To adjust the dehumidification setpoints: 1. Press MENU key to go to the Main Menu screen. 2. Press UP or DOWN keys and ENTER key to enter USER password 2000. 3. Press UP or DOWN keys to scroll to Sys Config; press ENTER key. 4. Press UP or DOWN keys to scroll to Unit Setup A4; press ENTER key. 5. Press ENTER key to scroll to Dehum Off (see Figure 39). 6.

FIGURE 39 Adjusting Dehumidification Setpoints Freecooling (Economizer) Operation Changing the Vent Package model number value to a "B" (see wall mount unit model nomenclature in unit installation or service instructions) simulates a blankoff plate configuration and will disable economizer function for the unit, with the exception of emergency ventilation functions. When the vent package model number value is changed to "B", the economizer control type listed on screen B1 (see Figure 40) will change to None regardless of system ventilation control type. The economizer has four types of operation. The first mode is "None" where the economizer is never utilized, except for emergency purposes. The second mode is "Dry Bulb" where the outdoor temperature is the only consideration for economizer use on a free cooling call. The third mode is "TempHum" where the outdoor temperature and humidity are considered for economizer use on a free cooling call. The fourth mode is "Enthalpy" where the outdoor temperature, humidity and calculated dew point are considered for economizer operation on a free cooling call. To change the economizer type: 1. Press MENU key to go to the Main Menu screen. 2. Press UP or DOWN keys and ENTER key to enter TECHNICIAN password 1313. 3. Press UP or DOWN keys to scroll to Adv System Config; press ENTER key. 4.

FIGURE 42 Last 24 Hours Tracking Manual 2100-673I Page 33 of 45 TROUBLESHOOTING 8403-079 Remote Indoor Temperature/Humidity Sensor Troubleshooting the temperature/humidity sensor is necessary if the temperature or humidity reading for a zone is inaccurate. Always start sensor troubleshooting by verifying connections at the sensor board and at the LV1000 terminal blocks. Improper connection will cause inaccurate readings. Next, verify continuity at both ends of wires running between the sensor and the LV1000. A severed or damaged wire will cause inaccurate readings. As a last step, verify voltage and resistance at the sensor and the LV1000 terminal block per Tables 8 and 9 on the following pages. If the sensor is found to be malfunctioning, replace the sensor.

A software upgrade of all PLCs onsite (units and controllers) should accompany any PLC replacement. Latest revisions of software and instructions are available on the Bard website at http://www.bardhvac.com/software-download/ Previous LV1000 controllers (LV1000-100, -150, -200) use the Core 0 style PLC which requires a separate software update package than the Core 2 style PLC. The 8301-098-001 is the active replacement board for any future replacement parts. To identify the Core syle of the PLC, see Figure 47.
