SECTION 1 - INTRODUCTION

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 OptiView™ 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.

The SC-EQ kit includes the SC-EQ board and the re-

lated installation accessories. The OptiVew kit does not

include the SC-EQ board.

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.

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 OptiView, Latitude, and IPU-II based Micro Panels.

IMPORTANT: Do not install the SC-EQ Comm Card directly into an equipment’s enclosure without the use of an approved installation kit.

WIRING

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.

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.

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 Elec-

tromagnetic Interference (EMI).

Grounding

For the enclosure style, a ground wire must be connect-

ed directly to the enclosure supply power ground lug at

the point of entry. A label (Figure 1 on page 11) iden-

tifies this grounding point. This ground wire should be

connected through a continuous ground circuit to the

incoming ground at the source transformer.

GRD

LD20000

FIGURE 1 - GROUNDING LABEL

Besides providing safety protection, the ground connection plays an extremely important part in the operation of the communication circuitry.

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

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 OptiView chiller, the Micro Panel supplies low-voltage power via a power harness supplied by the OptiView 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

JOHNSON CONTROLS

When using RS-485 technology, it is possible that elec-

trical disturbances, such as voltage spikes, can damage

a circuit board. The SC-EQ Comm Card includes reset-

table fuses and other devices on each RS-485 port to pro-

tect against damaging electrical spikes and stray voltage.

The equipment panel should also be equipped with pro-

tection against electrical disturbances. Whereas OptiView

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 elec-

trically isolated, providing a means of mitigating common

mode voltage induced problems.

FORM 450.50-N1

ISSUE DATE: 08/19/2019

HIGH NOISE ENVIRONMENTS

Electrical equipment that employs high speed switching circuits (Variable Speed Drives [VSD], Solid State Starters [SSS], and computing equipment) generates Electromagnetic Interference (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.

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 should be used to help mitigate the adverse effects electrical noise can have on the system. The double-shielded cable should connect the SC-EQ’s BAS port (J12) to the next controller(s) in the daisy-chained network.

The outer shield of the double-shielded cable should 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.

The inner shield of the double-shielded cable should 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 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 the panel. (see Figures 4 and 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 feet. The OptiView 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.

FIGURE 2 - RS-485 EOL SWITCHES

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 except older Yorktalk2 chillers requires that the chiller model manually be set using an SC-AP as explained in the SC-AP section of this manual. 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.

SECTION 2 - INSTALLATION

WALL MOUNTING

To mount the SC-EQ Enclosure on a wall:

When wall mounting, make sure there is no interference with other components in the near vicinity. Use appropriate conduit to connect the power and communications 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 Fig- ure 25 on page 23 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.

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.

7. Complete wiring as described in the Applying Power section.

EQUIPMENT CONFIGURATION

Different pieces of equipment sometimes require a specific hardware configuration (jumper, switch or software setting) to enable communication with the SCEQ Communication Card. Refer to the equipment’s installation literature for details on the proper configuration settings. The following diagrams summarize what these requirements are and the wiring interfaces for each of the different types of microboards.

LD20009

FIGURE 28 - MICROPANEL ROTARY SWITCH

SETTING THE ROTARY SWITCH ON CHILLER PANELS

Some Micro Panels use a rotary switch to set their YORK Talk II address (YORK Talk address = Rotary Switch setting + 1). 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 (refer to the equipment documentation for specific details).

SECTION 3 - TROUBLESHOOTING

LED INDICATORS

There are 9 LEDs on the SC-EQ Comm Card to indicate the operational status of the SC-EQ and the 3 communication ports. The LEDs on the SC-EQ and related communication LEDs on the chiller microboard should be observed to help diagnose communication problems.

LEDs/ USB

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 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.

FIGURE 38 - 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 +or- 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 communcations established with the SC-AP and the SC-EQ CS port is therfore 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.

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 should 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 then the MAC address should be checked to see if it is set to the desired address.

JOHNSON CONTROLS

Page 34

SECTION 3 - TROUBLESHOOTING

FORM 450.50-N1

ISSUE DATE: 08/19/2019

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 Transmittinging data to the microboard.

Normal Sequence - The Red ETX LED is illuminate 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 it's 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 perfroming 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 500ms 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.

Firmware Programming Required - The LED is ON solid indicating no firmware is present. A firmware update should be performed 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 steady 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 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 39 on page 35. 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 39 on page 35. 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

JOHNSON CONTROLS

FORM 450.50-N1 ISSUE DATE: 08/19/2019

SECTION 3 - TROUBLESHOOTING

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 onthe BAS Bus then the voltage measured in step 4 should uctuate 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 voltme-

ter used. If the voltage readings are uctuating 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 should be corrected at the EOL device.

USING THE SC-AP FOR TROUBLESHOOTING

SECTION 4 - SC-AP GATEWAY

The SC-AP is a device that interfaces with Johnson Controls Connected Chillers service. 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. Refer to page 34 for instructions on how to manually set the chiller model. For more detailed information on the SC-AP refer to SC-AP Installation

Instructions (Lit 24-10737-75) and SC-AP Quick Start (Lit 24-10737-75).

The first screen displayed on the SC-AP after login is the Device List screen, as shown in Figure 46 on page 39). The example shows two devices, the SCAP, 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 Online/Offline status of the ports. Refer to Figure 47 on page 39.

The SC-EQ Port Status shows that the Equipment Port is communicating using YorkTalk 3 and the BAS is 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.

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 SC-AP Installation (Lit 24-10737-75) and SC-AP Quick Start (Lit 24-10737-87) 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 can not 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 48. 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.

FORM 450.50-N1

ISSUE DATE: 08/19/2019

E-LINK REPLACEMENT

In BACnet autodiscovery, 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 Electro-Mechanical starter, the parameters for a VSD starter were shared by the E-Link 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 non relevant 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.

MANUALLY SETTING THE CHILLER MODEL

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

SECTION 4 - SC-AP GATEWAY

but the Auto Detected Chiller Model is NONE, an additional field is displayed named MANUALLY SELECTED CHILLER MODE. See Figure 52 on page

41. Clicking on this field allows the user to select the chiller model that the SC-EQ is connected to. See Figure 53 on page 41. Field 46 allows manual EQ Port starting point after a power loss.

OVERVIEW

SECTION 6 - LON PROTONODE

The LON ProtoNode in conjunction with the SC-EQ communication interface card provides YORK® chillers LON network connectivity. 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.

LONWORKS

SERVICE PIN

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 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 OptiView panels, 24 VAC is not provided. For YS OptiView panels the +12 VDC power to the SC-EQ board is extended to the ProtoNode.

NOTE: The information below can be shared with the technician responsible for the BAS network.

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.

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 s.
