Introduction 1 Overview The SC-EQUIP (SC-EQ) Communication Card supersedes the E-Link Gateway and provides BAS network connectivity for Johnson Controls® and YORK® mechanical equipment, such as chillers and rooftop units. It is designed with four active serial ports: The J12 BAS (RS-485) port, the J7 Equipment (RS-232) port, the J8 Equipment (RS-485) port and the J11 CS port which allows equipment data to be sent to the Johnson Controls Remote Operation Center for remote chiller monitoring and diagnostics. To simplify the installation and setup, the SC-EQ Comm Card automatically determines the BAS protocol and Baud rate and the model of the connected chiller or rooftop unit. The only user setting is the MAC address for the SC-EQ on the BAS network. Several SC-EQ Comm Card models are available for connection to various types of input voltage and equipment. For chillers using the OptiViewTM 02430 or 03630 microboards, the SC-EQ Comm Card consists of a single circuit board attached to four studs inside the Micro Panel, using the accessory mounting kit. The microboard supplies 12 VDC input power, eliminating the need for an external power supply. The SC-EQ plug J10-COM needs a ground wire to ground the lug on the panel. For screw compressor chillers using the 02478 or 03478 microboards, the SC-EQ Comm Card is installed inside the Micro Panel, using the accessory mounting kit. The microboard supplies 12 VDC input power, eliminating the need for an external power supply. For scroll compressor chillers using the 02050 or 02550 microboards, the SC-EQ Comm Card is installed inside the Micro Panel and requires an additional transformer to supply power to the SC-EQ Comm Card. The transformer is included in the SC-EQ Scroll Chiller Installation Kit. For other types of chillers, the SC-EQ Comm Card is packaged in its own enclosure. In addition to the SCEQ circuit board, a transformer is included inside the enclosure that converts a 120 VAC or 240 VAC input to 24 VAC power.

JOHNSON CONTROLS 9 Section 1 - Introduction Emissions compliance United States 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 is likely to cause harmful interference, in which case the user is required to correct the interference at his/her own expense. Form 450.50-N1 Issue date: 11/26/2021 Canada This Class (A) digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment Regulations. Cet appareil numérique de la Classe (A) respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada. 10 JOHNSON CONTROLS Form 450.50-N1 Issue date: 11/26/2021 Section 2 - Installation The SC-EQ is supplied as a circuit board that can be installed directly into the equipment's enclosure, or can be supplied pre-mounted in an enclosure ready for line voltage. Accessory mounting kits are used to mount the SC-EQ Comm Card directly into OptiViewTM, Latitude, and IPU-II based Micro Panels. &$87,21 Do not install the SC-EQ Comm Card directly into an equipment's enclosure without the use of an approved installation kit. Wiring :$51,1* Risk of Electric Shock. Disconnect or isolate all power supplies before making electrical connections. More than one disconnect or isolation may be required to completely de-energize equipment. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. &$87,21 Risk of Property Damage. Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected wires may result in permanent damage to the equipment. Important: Make all wiring connections in accordance with local, national, and regional regulations. Install the wiring so it does not cause a hazard, and is protected against electrical and mechanical damage. Power The SC-EQ circuit board is powered from either a 12 VDC, or a 24 VAC, Class 2 power source. When used with an OptiViewTM chiller, the Micro Panel supplies low-voltage power via a power harness supplied by the OptiViewTM installation kit. If the SC-EQ circuit board is installed in its own enclosure, a transformer is included in the enclosure. Line voltage may be supplied using an external power source, or drawn from the input voltage terminal strip inside the chiller panel. Be sure the capacity of the power conductors supplying the equipment is rated for the additional power (VA) required by the SC-EQ Comm Card. Use a wire that is one size larger than required for the amperage draw (maximum 400 mA) to connect the line voltage feed 2 to the SC-EQ Comm Card. For the line voltage power source, use a dedicated line (with a separate fuse) that is isolated (using a control transformer) from other equipment in the plant room that may generate electromagnetic interference (EMI). Grounding For the enclosure style, a ground wire must be connected directly to the enclosure supply power ground lug at the point of entry. A label (Figure 1 on page 11) identifies this grounding point. This ground wire must be connected through a continuous ground circuit to the incoming ground at the source transformer. GRD Figure 1 - Grounding label LD20000 Besides providing safety protection, the ground connection plays an extremely important part in the operation of the communication circuitry. 127( :$51,1* Risk of Electric Shock. Ground the SC-EQ Enclosure according to local, national, and regional regulations. Failure to ground the SC-EQ Enclosure may result in electric shock and severe personal injury or death. Protection of communication ports When using RS-485 technology, it is possible that electrical disturbances, such as voltage spikes, can damage a circuit board. The SC-EQ Comm Card includes resettable fuses and other devices on each RS-485 port to protect against damaging electrical spikes and stray voltage. The equipment panel must also be equipped with protection against electrical disturbances. Whereas OptiViewTM Micro Panels are equipped with onboard tranzorbs, other equipment panels may require the addition of an external board. Refer to the equipment documentation for details. The BAS Port J12 of the SC-EQ Comm Card is also electrically isolated, providing a means of mitigating common mode voltage induced problems. JOHNSON CONTROLS 11 Section 2 - Installation High noise environments Electrical equipment that employs high speed switching circuits (Variable Speed Drives [VSD], Solid State Starters [SSS], and computing equipment) generates EMI noise and Radio Frequency Interference (RFI), which can generate transient voltage between ground points in the communication wiring. The RS-485 circuitry is designed to withstand some low transient voltage, but if this difference exceeds certain limits, it can permanently damage the RS-485 circuitry. Ensure that the Micro Panel and the SC-EQ Comm Card are powered from a source with a true earth ground. :$51,1* Important: Do not run communication cables in close proximity to, or parallel with, high-voltage power cables. Maintain at least 457.2 mm (18 in.) of separation, or use a grounded metal conduit. Electrical noise mitigation to equipment The likelihood of transient voltage is greatly reduced if the SC-EQ Comm Card is close-coupled to the Micro Panel. Close-coupling requires that the SC-EQ Enclosure and Micro Panel share the same line voltage power source and are physically close to one another. Typically, the SC-EQ Enclosure is mounted on the Micro Panel enclosure. This scenario ensures a short communication cable, which is usually protected entirely within the two enclosures. Electrical noise mitigation SC-EQ to BAS When the SC-EQ is used in an electrically hostile environment (for example, with VSD-enabled equipment), a double-shielded cable must be used to help mitigate the adverse effects electrical noise can have on the system. The double-shielded cable must connect the SC-EQ's BAS port (J12) to the next controllers in the daisy-chained network. The outer shield of the double-shielded cable must be grounded directly at the low noise end (the end most distant from the VSD), and ideally, indirectly through an appropriate capacitor at the high noise end (the end closest to the VSD). If a capacitor is not available, the outer shield may be left unconnected, or tied directly to ground. The best results on the site determine the specific termination strategy employed. Form 450.50-N1 Issue date: 11/26/2021 The inner shield of the double-shielded cable must be grounded directly at the low noise end (the end most distant from the VSD), and left open at the high noise end (the end closest to the VSD). Types of communication ports The SC-EQ Comm Card uses two electrical communication protocols to connect to other devices: RS-485 which is used for multi-drop networking, and RS-232, which is primarily used for point-to-point connectivity. RS-485 The RS-485 standard uses three conductors to connect network nodes: two signal wires and a third called COM which is the reference. The SC-EQ Comm Card uses either a third wire for the reference or the building's infrastructure. The wiring method depends on the port being used: an electrically isolated RS-485 BAS Port J12 typically uses a third wire, whereas the RS-485 Equipment Port J8 and the RS-485 Connected Services Port J11 normally use chassis or building ground for the reference. For BAS systems that use a 2-wire RS-485 network, connect a 100 ohm 1W resistor between SC-EQ J12 COM and J10 COM with a wire that then runs to Ground in 127( the panel. See Figure 4 and Figure 5. RS-232 The RS-232 Standard also uses three conductors to connect network nodes: two signal wires and a third called COM which is the reference. RS-232 is more susceptible to noise interference than RS-485 so proper shielding and wire routing is essential for proper operation. The RS-232 Standard limits the cable run to a maximum of 50 ft. The OptiViewTM panels use RS-232 to communicate with the SC-EQ. Network termination Terminate all End-of-Line (EOL) devices at each end of the RS-485 bus (that connect to only one set of RS-485 network wires). EOL termination provides biasing of the network, and assists in returning the signal to a normal state in the event of voltage transients. If the SC-EQ Comm Card happens to be an end-of-line device on the Building Automation System network, terminate the network by setting the BAS EOL switch S2 to ON. 12 JOHNSON CONTROLS Form 450.50-N1 Issue date: 11/26/2021 BAS Port J12 O1 N O1 N RS485 RS485 Port EOL Port EOL Not Terminated Terminated Figure 2 - RS-485 EOL switches LD20001 Important: Ensure that the EOL switches are not set to the ON position for controllers that are not at the end of the BAS RS-485 network. Media access control (MAC) address The SC-EQ Comm Card's network hardware address is set on a single 8-way DIP switch. Switch 8 is not used. The switches are binary weighted allowing the setting of addresses from 1 to 127. The address must be provided by the BAS contractor. If an address is not provided at chiller commissioning, leave the MAC address set to 0 (all switches OFF) and leave a copy of the last page of this manual taped on the chiller panel for the controls contractor. The last page explains how to set the MAC address. The SC-EQ automatically determines what BAS protocol is present and what chiller is connected. Older YorkTalk2 chillers require that the chiller model manually be set using a SMART Chiller Access Portal (SC-AP) as explained in Section 4 - SCAP gateway on page 41. This should eliminate the need for a chiller technician to have to return to site after the chiller has been commissioned just to set the BAS Network MAC Address. Important: The SC-EQ Comm Card is intended to provide an input to equipment under normal operating conditions. Use this SC-EQ Comm Card only as an operating control. Where failure or malfunction of the SC-EQ Comm Card could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of, or protect against, failure or malfunction of the SC-EQ Comm Card.

For mounting on a Micro Panel, the line voltage power is supplied by a power source in the Micro Panel. Important: Make sure that the cover is securely fastened to the enclosure and the internal ground wire is attached before placing the SC-EQ in operation. These steps help to minimize RFI from being generated and picked up. Mounting on a micro panel Risk of Electric Shock. Disconnect or isolate all power supplies before making electrical connections. More than one disconnect or isolation may be required to :$51,1* completely de-energize equipment. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. Important: When attaching the SC-EQ Enclosure to a Micro Panel, ensure the SC-EQ Enclosure does not impede access to other components. To mount the SC-EQ Enclosure on a Micro Panel, complete the following steps: 1. Disconnect power to the chiller Micro Panel. 2. Make sure the SC-EQ Enclosure fits properly and that no obstructions, such as internal boards, switches, or external conduit, prevent mounting or servicing of the panel. See Figure 24 on page 21 for examples of good mounting locations. 3. Locate and remove the two plastic caps in the bottom of the SC-EQ Enclosure. Section 2 - Installation 4. Mark an appropriate place on the enclosure for a matching set of knock out holes. Mark and drill, or punch, two holes in the Micro Panel. Using two bulkhead pipe couplers, attach the SC-EQ Enclo- 2 sure to the Micro Panel. 5. Complete wiring as described in the Applying Power section in this document. Important: Be careful not to damage the SC-EQ or Micro Panel's circuit boards during the installation. Protect all circuit boards from metal chips, which may cause short circuits if left on the boards at startup. Use of bulkhead pipe couplers provides sufficient clearance to allow removal of the SC-EQ Encloser cover. 127( SC-EQ Enclosure ISN MicroGateway YORK Chiller Micro Panel 177.8mm (7 in.)

Use appropriate conduit to connect the power and communications 127( wiring. 1. Check for proper clearances for the necessary electrical and communications cable runs. 2. Ensure that power and communications wiring is in compliance with all local, national, and regional codes, and customer requirements. 3. Select a suitable location and mark the anchor points. Ensure that the enclosure is level. See Figure 37 on page 26 for an example. 4. Drill the appropriate holes in accordance with the type of wall anchor used. 5. Install the enclosure on the wall. 6. Check that the mounting is secure and the wiring connections are correct and tight. Check that no loose wire strands or other metal objects that could cause a short circuit are on the circuit board. 7. Complete wiring as described in the Applying power section. YORK Chiller Mirco Panel Conduit Form 450.50-N1 Issue date: 11/26/2021 Applying power When using an enclosure type of SC-EQ, power can be supplied from either a separate power supply or the main terminal strip in the chiller panel. Locate the power source within 0.9 m (3 ft) of the SC-EQ Enclosure, and protect it with a suitable fuse or circuit breaker. Ensure the power is supplied from a dedicated source and not controlled by a programmed switch. If the enclosure is mounted on a wall, the wiring from the power source to the SC-EQ Enclosure must always run in a suitable conduit. To obtain the best Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) performance, ensure that the conduit is bonded to the metal of both enclosures. Scraping the paint around the knockouts usually helps provide a better electrical connection between the joining parts. :$51,1* Risk of Electric Shock.

Since the SC-EQ uses a one-toone relationship with the chiller panel, this switch is normally set to 0 (YORK Talk address 1). However, when two microboards are used in a BACnet MS/TP configuration, set the master microboard rotary switch to 0, and the subordinate microboard is set to 1. If the chiller microboard is not equipped with a rotary switch, the YORK Talk address is set using the Micro Panel keypad and display. In most cases, you can configure the setting, but some models are fixed and cannot be changed.

To help diagnose communication problems, monitor the LEDs on the SC-EQ and the related communication LEDs on the chiller microboard. LEDs/ USB Figure 50 - SC-EQ LEDs and USB LD19992a Power A Green LED that is ON whenever power is applied to the SC-EQ Comm Card either by the 24 VAC (20.4 to 30 VAC) input or the +12 VDC (+12 VDC ±10%) input. The Power LED should always be illuminated. If not, then a digital multimeter should be used to verify the power source to the SC-EQ is present or not. If the power source is present at the SC-EQ power terminals (J9 +12 VDC [Red wire + Black wire - ] or J10 24 VAC as applicable) and the Power LED is not illuminated then the SC-EQ is faulty. Connected services network CS BUS - A Green LED that indicates the communication activity on the Connected Services communication port. It blinks ON and OFF every 500ms to indicate that communications is established with the SC-AP. The LED is ON solid when there are no communications established with the SC-AP and the SCEQ CS port is polling for a Master. If the LED is OFF continuously then the SC-EQ is waiting for the SC-AP to start polling the SC-EQ. BAS network BS BUS - A Green LED that indicates the communication activity on the BAS communication port. The LED illumination has two variations depending upon 3 the protocol present on the BAS port. BACnet MS/TP - The LED is OFF when there are no active BACnet communications on the network. It is also OFF when it is initially auto-bauding and waiting for a master device to poll on the network. The LED illuminates ON when the SC-EQ sees any communications on the network. N2 and Modbus RTU - SC-EQ receives a request from the Master to the SC-EQ network address. The LED then illuminates while the SC-EQ is transmitting the response message. There are two additional LEDs on the BAS Port to aid in diagnosing BAS Network Integration problems. BRX - A Green LED that illuminates when the SC-EQ is Receiving data on the BAS Network Port. BTX - A Red LED that illuminates when the SC-EQ is Transmitting data on the BAS Network Port. Normal Sequence - The Green BRX LED illuminates whenever there is a data packet sent on the BAS network to any address. If this LED illuminates for a short period of time, then it indicates that the BAS Port RS-485 receive circuitry is functioning. If the BRX illuminates solid, then the + and - RS-485 wires are probably swapped and must be corrected. If the data message address matches the SC-EQ address, then the SC-EQ responds with the requested data and the Red BTX LED illuminates during the response. If the BAS system is polling the SC-EQ but the SC-EQ is not responding, check the MAC address to see if it is set to the preferred address. JOHNSON CONTROLS 37 Section 3 - Troubleshooting Equipment network EQ BUS - A Green LED that indicates the communication activity between the SC-EQ and the chiller Microboard. The SC-EQ acts as the Master in this network and issues data requests to the chiller Microboard. The EQ BUS LED blinks as it receives a valid response from the chiller Microboard. The data is requested one parameter at a time so the blink rate is almost constant. There are two additional LEDs on the Equipment Port to aid in diagnosing communication problems with the microboard. ERX - A Green LED that illuminates when the SC-EQ is Receiving data from the microboard. ETX - A Red LED that illuminates when the SC-EQ is Transmitting data to the microboard. Normal Sequence - The Red ETX LED is illuminated when the SC-EQ sends a request for data to the chiller microboard. The microboard Receive LED should then illuminate. The microboard should then illuminate its Transmit LED as it sends the requested data and the Green ERX LED on the SC-EQ should illuminate. If the SC-EQ ETX light illuminates and the micoboard Receive LED illuminates but no response is transmitted from the microboard check that the chiller address is set to 1. For microboards with a rotary switch set to 0 which is interpreted as a 1. If the address is set in the software, then it should be set to 1. Fault A red LED that indicates a problem with the SC-EQ Firmware or indicates the status during a program update. Power-Up - The LED blinks while the SC-EQ is initializing and performing self checks. Normal Operation - The LED should normally be OFF. Firmware Update - The LED blinks at a 100 ms cycle while the Firmware is updating. Unable to Load Firmware - The LED blinks at a 500 ms cycle to indicate that the SC-EQ could not load a firmware update. Try loading the firmware update on to another USB thumb drive and perform the update again. Firmware Validation Failure - The LED blinks at a 1 second cycle whenever the SC-EQ fails to validate the firmware at intial power up or after a firmware upgrade. Try cycling power to the SC-EQ and updating the firmware again. Form 450.50-N1 Issue date: 11/26/2021 Firmware Programming Required - If the LED is ON solid, then no firmware is present. Complete a firmware update to remedy this. Multimeter checks of the BAS port If the SC-EQ board is connected to a BAS bus but the BS BUS LED is off continuously, then the SC-EQ board is not likely seeing any valid communications occurring on the BAS bus. Simple voltage measurements with a DC voltmeter can be made on the SC-EQ board and the BAS communication bus to help diagnose the problem. 1. Remove the BAS plug from the SC-EQ J12. 2. Note the position of the BAS End Of Line (EOL) Switch S2. If the SC-EQ is not the EOL device, the EOL switch must be OFF. If it is the EOL then set the EOL to ON temporarily for these tests. 3. Measure the voltage between the + and pins on the BAS Bus Terminal Block as shown in the top portion of Figure 51 on page 39. The positive lead of the voltmeter should be on the + pin of the block and the negative lead of the voltmeter on the pin of the block. The voltage reading can fall in the range of (0.38 VDC to 0.47 VDC). The reading should be steady and only changing by a couple of millivolts at the most. If the reading is within the range of (+0.38 VDC to +0.47 VDC) that is an indication that the BAS transceiver on the SC-EQ board is not damaged. If the voltage reading is out of the range given by a large amount, the transceiver or its associated circuitry may be damaged. Again verify that switch S2 (BAS EOL) is in the "ON" position during the measurement otherwise the voltage readings are out of the given range. 4. If the reading in step 3 is within the given voltage range then return switch S2 (BAS EOL) to its proper position and connect the BAS terminal block plug back into the BAS terminal block J12 on the SC-EQ board. Take another VDC voltage reading now on the BAS plug between the + and wire connections as shown in the bottom portion of Figure 51 on page 39. If the BAS bus is connected to a JCI BAS bus with proper EOL terminations set then the voltage range should be steady and in the (0.38 VDC to 0.47 VDC) voltage range if NO 38 JOHNSON CONTROLS SHLD COM - + - COM SH LD Form 450.50-N1 Issue date: 11/26/2021 communications are occurring on the BAS bus. If the voltage reading is steady but out of the (0.38 VDC to 0.47 VDC) voltage range then the issue could be improper EOL terminations, issues with wiring, or some other issue. If the BAS trunk is connected to a third party BAS then the voltage readings could be acceptable anywhere between (0.25 VDC to 0.5 VDC). 5. If communications are occurring on the BAS Bus then the voltage measured in step 4 should fluctuate generally in the range of (0.1 VDC to 0.5 VDC) if the bus is properly terminated. The voltage readings may vary somewhat out of this range depending on bus loading and the type of voltmeter used. If the voltage readings are fluctuating in the approximate range of (1.5 VDC to 3.5 VDC), then it is likely there is no End of Line (EOL) termination set on the bus and that must be corrected at the EOL device. + BAS Bus Terminal Block - V+ - V+ BAS Bus Terminal Block Plug LD19997 Figure 51 - BAS bus meter checks The meter checks detailed for the BAS port can also be used for the CS and EQ ports. 127( Section 3 - Troubleshooting Updating the firmware and the software When new chiller data maps become available, you must update the SC-EQ firmware and software.

This device can also be used to troubleshoot connectivity issues. If an SC-AP is installed as part of a Connected Services installation, or if an SC-AP is available otherwise, connecting it to the SC-EQ allows the technician to view the port activity to aid in communication problem diagnosis. It is also required to manually set the Chiller Model on older YorkTalk2 chillers that do not auto-discover. See page 45 for instructions on how to manually set the chiller model. For more detailed information on the SC-AP, refer to SMART Chiller Access Portal Installation Guide (Part No. 24-1073775) and SMART Chiller Access Portal Gateway Quick Start Guide (Part No. 24-10737-83). The first screen displayed on the SC-AP after logon is the Device List screen, as shown in Figure 58 on page 43). The example shows two devices, the SC- Section 4 - SC-AP gateway AP, and the SC-EQ, as well as their MAC address. The SC-AP is always MAC address three. In the example below, the SC-EQ has MAC address four. The Device List can be used to help troubleshoot issues where the BAS is not connecting to the SC-EQ. Selecting the SC-EQ Data tab displays the data for the SC-EQ. Four of the parameters in the SC-EQ Data tab display the three communication port settings and the 4 Online/Offline status of the ports. Refer to Figure 59 on page 43. The SC-EQ Port Status shows that the Equipment Port is communicating using YorkTalk 3 and the BAS uses Modbus. The CS port is always BACnet MSTP. If either the BAS or the EQ port are not active for a short period of time, the status is displayed as "Offline." If the communications is not present for a few minutes, the status is displayed as "No Protocol." The SC-EQ continually tries to connect to the absent ports. Figure 58 - SC-AP device list LD19990 Figure 59 - SC-EQ port status and lock in JOHNSON CONTROLS LD29237 43 Section 4 - SC-AP gateway To change the device instance The SC-EQ automatically creates the Device Instance as 5000 plus the MAC Address switch setting. For example, if the MAC address DIP switches are set to a value of 6, the Device Instance is 5006. Some customers require the Device Instance to be something other than the automatically generated 5000 series address. The SC-AP can be used to change the Device Instance to the customer desired address. Connect the SC-AP to the SC-EQ and log on to the SC-AP using a WiFi interface either from a Smartphone, a Laptop, or Tablet PC. Refer to SMART Chiller Access Portal Installation Guide (Part No. 24-1073775) and SMART Chiller Access Portal Gateway Quick Start Guide (Part No. 2410737-83) for more information on the SC-AP. Note that any MAP 4.0 device may be used to connect to the SC-EQ to change the Device Instance and to also look at the communication port status. It is not able to communicate with the Cloud though. When you first click on a MAP 4.0 device, the Home page loads and displays a "spinner" that never stops since it is looking to connect to a Simplicity SE or a RTU controller and cannot find them. The user must just proceed to click on a menu item on the left-hand side to view information. The MAP1810 device uses two MAC address of 2. So a temporary change of the SC-EQ mac/node address 2 allows a CS port port mac/node# change as shown in Figure 60. The virtual MAC address is separate from BMS. When it finishes, the address can return to 2. 1. Select the SC-EQ Device then select the SC-EQ Data tab. Figure 60 - SC-AP device list LD29329 A list of parameters is shown on the right side of your WiFi Smartphone or PC screen. 2.

Next, select the SC-EQUIP BACNET INSTANCE ID and change it to the desired value. This must be a number from 1 to 4914302. LD19998 E-Link replacement In the BACnet auto-discovery (within Metasys), in order to keep most of existing FQRs, check for the extended name of the E-Link that is being replaced first. Then delete the E-Link device. Using the MAP SC-AP, access the SC-EQ name and use the extended name in the field, or rediscover the SC-EQ and use that same extended name within Metasys. This then rebinds the Metasys programs that had bindings to the E-Link on version K switch setup used for OptiView panel installs. On non-OptiView panels, the Version J switch setup on E-Links also keep the binding The E-Link transferred a list of all possible chiller parameters to the BAS, even ones that did not apply. For example, if you had an electromechanical starter, the parameters for a VSD starter were shared by the ELink and auto-discovered by the BAS. The SC-EQ discovers what type of chiller is connected and the chiller features and then exposes only the relevant points to the BAS. If an E-Link is replaced by an SC-EQ, the BAS shows the points that were nonrelevant previously as Offline. To resolve this, you either need to delete the E-Link and re-discover the SC-EQ or delete each of the inappropriate Offline points. Figure 62 - Invalid points offline LD19994 JOHNSON CONTROLS Form 450.50-N1 Issue date: 11/26/2021 Section 4 - SC-AP gateway BAS commands Points that are commandable show as Unreliable until the BAS sends the setpoints. Figure 63 - Unreliable remote setpoints LD19993 Manually setting the chiller model Chillers that communicate through the EQ port of the SC-EQ by either YorkTalk-2 (YT2) or Modbus-subordinate protocols can be manually selected during commissioning. The manual selection steps for YT2 chillers no longer requires the loading of the Generic chiller model. Instead, the user selection directly causes the chiller model to load into the SC-EQ operating memory. Likewise, the Modbus chillers are included within the list of Manually Selected chillers. Manual installation instructions Some of the older YorkTalk2 chillers do not have programming in place to tell the SC-EQ their chiller model. In these instances, a SC-AP needs to be used to tell the SC-EQ what chiller is present. On the SC-AP SC-EQUIP DATA screen, when the Auto Detected Chiller Protocol is displayed as YorkTalk2 but the Auto Detected Chiller Model is NONE: This condition only applies when a YorkTalk2 chiller is actively attached to the SC-EQ. Some of the Modbus chillers do not identify their model type over the Modbus protocol. When that occurs, then the MANUALLY SELECTED CHILLER MODEL selection can be used to load the appropriate Modbus chiller model into the SC-EQ. See Figure 64 on page 46. Clicking on this field allows the user to select the chill- er model that the SC-EQ is connected to. See Figure 65 on page 46. A few seconds after the selection is applied, the SC-EQ begins to reprogram, the Current- ly Loaded Equipment Model. This may take up to 8 minutes to complete. Upon completion of this manual chiller selection, the SC-EQ reboots and then begins to run using the chiller model as the Currently Loaded Chiller Model Number. 4 The EQ Port Locked Protocol allows manual EQ Port starting point after a power loss. The SC-EQ has a Generic selection for YorkTalk-2 chillers within the Manually Selected Chiller Model list (Enum-set 2017). The V4.0 project for the SCEQ includes manually selected Modbus chillers into this same Manually Selected Chiller Model list. The Generic entry could be confused as either applied to YorkTalk-2 or Modbus. The Generic selection is intended for Generic YorkTalk2 chillers only and not Modbus chillers. 127( Whenever the Modbus address of the chiller is modified, then the SC-EQ fails to retrieve point data and continues to use the old/invalid Modbus address. The SC-EQ never times out and then attempts to rediscover the new Modbus address of the previously connected chiller. After changing the address of the BAS or SC-EQ connected devices, it is recommended to reboot the SCEQ. Use Table 8 for manual Modbus addresses.

It is designed with two active serial ports: · A LON port, which is used to connect to a LON FTT10 network. · An RS485 port, which connects to the BACnet MS/TP BAS port J12 on the SC-EQ. The ProtoNode also contains an Ethernet port that can be used for troubleshooting or to update the ProtoNode firmware, if needed. To simplify the installation and setup, the LON ProtoNode comes preconfigured. The switches and internal jumpers are preset at the factory for the correct node ID, baud rate, and configuration file type. There are no user switch settings required in the field. The ProtoNode polls the SC-EQ and chiller micro board to determine what model chiller and what points are available. This is based upon the options installed and configuration of the chiller. The ProtoNode then dynamically creates the LON points list. One ProtoNode part number covers all the various chiller models. If a firmware update is needed, the user can add the new ProtoNode firmware through the Ethernet port. A LON interface file named fserver.xif is also available from this port. The .xif file allows the LON Integrator to engineer and bind the chiller points offline. This file is automatically generated based upon the chiller 6 model and options installed. The LON ProtoNode consists of a single module mounted inside the chiller control panel. In most cases, the chiller control panel supplies 24 VAC input power, eliminating the need for an external power supply. For YS OptiViewTM panels, 24 VAC is not provided. For YS OptiViewTM panels the +12 VDC power to the SC-EQ board is extended to the ProtoNode.

If this occurs, immediately report the related system error shown in the error screen of the GUI to support for evaluation. RX If the socket protocol is serial, the RX LED flashes when the host port receives a message. If the socket protocol is Ethernet, the RX LED is not used. TX If the socket protocol is serial, the TX LED flashes when a message is sent on the host port. If the socket protocol is Ethernet, the TX LED is not used. PWR THE PWR LED is the power light and shows steady green at all times when the unit is powered. Binding the points using the .xif file If you want to bind the points using the .XIF file, complete the following steps the retrieve it from the ProtoNode: 1. Connect a CAT 5 Ethernet cable (Straight-Thru or Cross-Over) from the PC to the ProtoNode. 2. Turn off the Wi-Fi on the PC, so it does not try to connect to a network. 3. Set the PC to a static IP address 192.168.1.11, Subnet Mask 255.255.255.0. 4. Open the Internet Browser and navigate to the ProtoNode address for the .xif file: 192.168.1.24/ fserver.xif. 5. Save the .xif file to the PC. 54 JOHNSON CONTROLS Form 450.50-N1 Issue date: 11/26/2021 Section 6 - LON ProtoNode Technical specifications Table 15 - Technical specifications Electrical Connections One 6-pin Phoenix connector, one RS-485 +/- ground port, power +/- frame ground port One Ethernet 10/100 BaseT port, One FTT-10 LonWorks port Approvals CE Certified; TUV approved to UL 916, EN 60950-1, EN 50491-3 and CSA C22-2 standards; FCC Class A Part 15; DNP3 Conformance Tested; RoHS Compliant; CSA 205 Approved LonMark Certified Power Requirements 9 VDC to 30 VDC or 12 VAC to 24 VAC Physical Dimensions (Lenght x Width x Height) 11.5 cm x 8.3 cm x 4.1 cm (4.5 in. x 3.2 in. x 1.6 in.)

Instructions for the BAS contractor The SC-EQ Communication Card has the ability to automatically determine the BAS network protocol and communication parameters and set its communication parameters to match the installed BAS system. If the chiller was already commissioned, there is no need for a chiller technician to return to the site to connect the BAS wiring and set the MAC address since these are standard tasks that a BAS contractor routinely performs. The instructions on this page assist you with these steps. BAS wiring connections The BAS port J12 is the blue pluggable connector shown below. It is an RS-485 port with + - COM and SHLD marked. The SHLD (shield) terminal is not connected to any circuitry or ground and provides a convenient location to connect the shields of two daisychained segments. On some BAS systems the COM is called REF. The J12 blue plug is used for the BACnet, Modbus, or N2 connection for the BMS (Building Management System). 127( Setting the MAC address The SC-EQ Communication Card Media Access Control (MAC) network hardware address is set on a single 8-way DIP switch. Switch 8 is not used. The switches are binary weighted allowing the setting of addresses from 1 to 127. Once the DIP switches are set for the correct MAC address, cycle the power to the SC-EQ by momentarily unplugging the 24 VAC or +12 VDC power plug (depending upon how the SC-EQ is being powered). The SC-EQ Communication Card then boots up and establish communications. This may take up to 120 seconds.
