System Requirements

SECTION 12: WCC III INST ALLA TION GUIDE __________________________________________

WCC III System Requirements

To accomplish remote communications via the internet, the following items are needed in addition to the WCC III system in order to control the building mechanical systems. The WCC III system is not to be used in any application where Fire/Life/Safety is an issue.

WCC III – MCD System Requirements (On-Site WCC III – MCD Computer):

• DSL, or a Cable router/switch that connects to the

internet. Or, as an alternative, an internal jobsite IP network that does not connect to the internet, but when using this internal jobsite IP network, the external internet Email of alarms from the WCC III

- MCD will not be possible. Also, external access via the internet may not be possible.

• A ﬁ xed static IP address or a ﬁ xed IP domain host

name.

• Enabled port forwarding on the Firewall of the

router/switch. This is only if a ﬁ rewall is used.

• On earlier versions, antivirus software is initially

provided by WattMaster Controls, with Norton antivirus software for a period of 1 year. The customer must maintain the antivirus software after this 1-year period. Later versions are shipped with Linux as the operating system and do not require anti-virus software.

• An Email address that supports a SMTP

server for SENDING with a pop server for RECEIVING Emails, and it must have “auth login” authentication. TLS or SSL modes are not supported. WattMaster Controls can provide an Email address with these requirements.

• An Uninterruptible Power Supply (UPS) – 750-

Watt minimum

• A wall mounting surface is preferred.

• A dedicated 120VAC power circuit is required.

Front End Software Requirements (Operator Console Software):

• A Microsoft Windows XP /Vista/Windows 7-based

computer.

• Minimum hardware speciﬁ cation for the Microsoft

Windows XP / Vista based computer is a Pentium IV running at 2.4 Giga Hertz with at least 1 GB of RAM, and 10 GB of spare hard drive space. A CDROM/DVD player is also required for software installation.

• WCC III software package – Provided on a

CDROM, or is available via a download on the WCC Controls website: www.wcc-controls.com. The installation CDROM contains the following programs:

WCC III.EXE (SS5021) WCCUTILITY.EXE (SS5023) SCUSCR.EXE (SS5026) WCC3Trendlog.EXE (SS5028) TenantReport.EXE (SS5025) TenantOverride.EXE* (SS5024) WGCC3.EXE (SS5029) WCC3 Download (SS5030) WCC3 Guest (SS5022)

• The CDROM part number (WattMaster Part #

DM1WC011-01X, were “X” = revision level)

• A DSL or Cable router/switch that connects to the

internet, or access to the internet via some other method. Or, as an alternative, an internal jobsite IP network that does not connect to the internet, but when using this internal jobsite IP network, the external internet Email of alarms from the WCC III

- MCD may not be possible.

* NOTE: The TenantOverride.exe program is also available

as a single program installation for the end users that are using the simplistic graphical interface of the TenantOverride.exe screen to locally turn on and off speciﬁ c control points that are applicable to the end user.

Basic Operating Conditions and Wall Mounting

The WCC III – MCD Basic Operating Conditions

The WCC III - MCD must be kept in a clean and dry area in the building. The ambient temperature must be between 50 and 100 °F, and the relative humidity must be kept between 0 and 90% (noncondensing). The interior components are cooled by ventilation fans within the WCC III – MCD unit, and therefore the unit should not be kept in tightly conﬁ ned or enclosed areas. The WCC III - MCD is primarily designed to mount on a wall with the supplied brackets.

The WCC III – MCD computer requires 115 VAC power and must remain powered at all times for proper operation and control. The 115 VAC power circuit must be separate and dedicated exclusively to the WCC III – MCD computer.

The WCC III - MCD system is designed to automatically restart after a power failure. However, the industrial computer which acts as the WCC III Master Communications Device will not automatically reboot unless the power is shut off cleanly and then restored cleanly. During most power outages, the incoming 115 AC voltage could have great ﬂ uctuations before the power ﬁ nally fails. In a like manner, brownouts will usually cause the industrial computer to “lock-up.” That is to say, the screen will continue to display on the monitor, but the cursor will not respond to the keyboard commands. To prevent this “lock-up” issue from happening to the WCC III – MCD, an Uninterruptible Power Supply (UPS) is required on each and every WCC III – MCD computer.

An Uninterruptible Power Supply (UPS) provides emergency power to keep the WCC III Master Communications Device (personal computer) on-line for several minutes after a primary power failure. The UPS regulates the incoming power to the computer and shuts the power off cleanly several seconds after the power outage, or brownout. When the primary power is restored, the UPS brings the MCD back on-line automatically. The WCC III system does not lose any information since all of the programs and user entered data are stored on either a disk in the MCD, on ﬁ rmware, or on battery backed memory in the satellite controllers.

Figure 12-1: Installing the six screws for the two wall mounting brackets of the WCC III – MCD Computer

Do not mount the WCC III – MCD computer straight into the drywall. The use of a ¾-inch plywood “Backer Plate Board” is required. You may want to paint this plywood “Backer Plate Board” to match the color of the wall before mounting to the wall.

See Figure 12-2 for further application.

Backer Plate Mounting Notes:

Use correct type of wall mounting anchors for mounting on a concrete wall for the mounting of the “Backer Plate Board” if and when mounting the Backer Plate Board to a concrete wall. Use at least 2-inch dry wall type screws if mounting the Backer Plate Board to a “Dry-Wall” type wall. Mount the “Backer Plate Board” so that the screws that are holding the “Backer Plate Board” are on the 16-inch centers of the wall studs where applicable.

Mount the WCC III - MCD 4-½ to 5-½ feet off of the ground on a suitable wall, in an air conditioned space. This area should not have any radio transmitting or telephone switching gear in the space, or near the space, or located on the back side of the adjacent wall.

Wall Mounting of the WCC III – MCD

It is strongly suggested that the WCC III – MCD is mounted on the wall. General guidelines are as follows:

Always install the supplied six screws for the two supplied wall mounting brackets for the WCC III – MCD Computer as shown in

Figure 12-1. Be sure to tighten the six screws so that they do not

loosen over time.

12-2

Do not block the airﬂ ow vents that are coming out of the WCC III- MCD. Do not apply paint to the WCC III-MCD enclosure. Do not cover the WCC III-MCD with any protective plastic while painting with the WCC III-MCD turned on. The UPS battery backup unit should be located within 3 or 4 feet of this WCC III – MCD.

WCC III - MCD Internet Access

WCC III – MCD Internet Access

The most common question asked is: Why does the WCC III – MCD computer need to have Internet access?

If WattMaster Controls factory assistance or troubleshooting is required for a WCC III system, a representative from the factory can access the system with a remote computer and view the same WCC III Screens as the end user or contractor in the building. This allows the end user or the contractor for the building installation to talk to the factory representative while they are both viewing the same screens.

The Emailing of important alarm notiﬁ cations for up to 60 Email Addresses is provided for from the WCC III – MCD.

The ability to send alarm notiﬁ cation via a text message to a cellular phone.

Secure Remote communications package (WCC III software) is provided for FREE. A CD-ROM is supplied for installation.

World-wide, multiple remote connections (up to 255 simultaneous connections possible)

On earlier versions, antivirus software is initially provided by WattMaster Controls, with Norton antivirus software for a period of 1 year. The customer must maintain the antivirus software after this 1-year period. Later versions are shipped with Linux as the operating system and do not require anti-virus software.

The ability for internet based tenant override requires internet access.

WCC III – MCD Cable Modem/Router T echnical Considerations

The WCC III-MCD uses internet access to e-mail alarms and to provide remote IP access for multiple remote WCC III operator programs.

The DSL / Cable modem USB connection should not be connected to any of the USB ports on the WCC III – MCD. The DSL / Cable modem Ethernet connection should only be connected to the Ethernet port on the WCC III – MCD if the DSL / Cable modem has a built-in internal router with Ethernet switch.

The use of a DSL / Cable modem with an external router that is then connected to the WCC III - MCD is also a recommended way to connect the internet to the WCC III – MCD. The use of only a plain DSL / Cable modem without an internal router with a built-in switch is not currently recommended by WattMaster Controls.

It is recommended that the WCC III-MCD computer be connected to the internet via a high-speed cable modem or NAT enabled router.

This is best accomplished by what is called Port Forwarding (also sometimes referred to as tunneling) and is the act of forwarding a network port (located External on the internet) to another network node (located Internal on the LAN). This technique can allow an external user (The WCC III program) to reach a port that is on a private LAN (Local Area Network) IP address (The WCC III MCD) from the outside via a NAT enabled router. This external port number that is used for the WCC III – MCD computer is port

39289.

Custom remote WCC III system programming or analyzing of the existing WCC III program is also available for a nominal charge.

Some cable modem devices may incorporate a router along with the cable modem functionality, to provide the LAN with its own IP network addressing. From a data forwarding and network topology perspective, this router functionality is typically kept distinct from the cable modem functionality (at least logically) even though the two may share a single enclosure and appear as one unit. So, the cable modem function will have its own IP address and MAC address as will the router.

12. WCC III INSTALLATION GUIDE

WCC III - MCD Internet Access

In a typical WCC III - MCD networking setup, internet access is through a DSL or Cable modem. This modem may then be connected to a router with a built in switch, (or typically the router with switch is also built-in to the modem) which is then connected to the internal LAN of networked computers by Ethernet cabling. The NAT enabled router is the only device that the Internet sees as it holds the public IP address. On the other hand, the WCC III – MCD, located behind the NAT enabled router, is invisible to the Internet as it holds a local IP address on the NAT enabled router. Port forwarding is necessary in the NAT enabled router because computers that are running the WCC III program will send information that is directed to the public IP address and the NAT enabled router needs to know where to send and then redirect that information to the WCC III – MCD.

NOTE: A DSL modem is not recommended due to yet

another layer of setup complexity. DSL modem/routers also have a maximum distance from the local telephone company’s

main central ofﬁ ce. That distance is 18,000 feet.

Step 1: You will need a high-speed cable or DSL modem/router

that is NAT enabled and it must be setup by the ISP, or by IT (Information Technology) knowledgeable personnel, and it must also be connected to the Internet.

The default IP addresses that the WCC III – MCD is shipped with are:

WCC III-MCD IP Address: 192.168.100.100

WCC III-MCD Subnet Mask: 255.255.255.0

WCC III-MCD Default Gateway: 192.168.100.1

WCC III-MCD Preferred DNS Server: 208.67.222.222

WCC III-MCD Alternate DNS Server: 208.67.220.220

The external port number that is used for the WCC III – MCD computer is port 39289.

For WCC III – MCD’s running windows set up the WCC III – MCD BACKTASK.EXE Program

Com Port # ____________

External Port Range ____________

Default for the backtask.exe program is Comm port # 5 and port # 39289.

Step 2: The following three items are needed from your ISP

(Internet Service Provider) in order to set up the Cable / DSL modem/router for stand alone internet access. The ISP should have already supplied a sheet of paper that has this important information on it.

WCC III - MCD Internet Access

Supported Networks

Only Microsoft based networks are currently supported by the WCC III system. Any of the older 10 base T only networks are not supported by the WCC III system, only 100 base T or faster networks are supported. (10/100 base T are OK) The slower the network, the slower the data returned from the WCC III-MCD will be displayed, and the faster speed is always better.

Also, network “hub” devices are not recommended, because “hub” devices divide the network’s bandwidth amongst the active connections that are connected to the network hub. For example, if you have a 16-port network hub on a 100 base T connection with 10 active connections, then your effective network speed is the same as a 10 base T connection.

A 10/100 base T network switch is the recommended connection to the WCC III-MCD device. A network switch device has a full 100 base T connection to all active ports at the same time.

Beneﬁ ts of Using a Separate DSL / Cable Modem Internet connection for the WCC III-MCD

1. It provides a layer of network isolation. A connection to the building’s internal computer network may not be desirable to the IT department. If the WCC III – MCD is connected to the building’s internal computer network an additional ﬁ rewall into the building’s internal computer network may be required.

2. A dedicated high speed internet connection is a faster connection. WCC III displayed data will be displayed quicker and updated faster.

How to send a T e xt Message to a Cellular phone via an Email from the WCC III system

Most cellular telephone providers have as a free* option (Charges may apply in some instances) an Email-to-TEXT service for their cellular phone plans. *Usually the cellular telephone providers will have an unlimited text messaging option in one or more of their plans.

When using Verizon cellular service, the text messaging email address for your phone is your 10-digit phone number followed by @VTEXT.com. For example, if your phone number is 1-555555-5555, your email address (for TEXT MESSAGING) would be 5555555555@VTEXT.com

When using Sprint cellular service, the text messaging email address for your phone is your 10-digit phone number followed by @messaging.sprintpcs.com. For example, if your phone number is 1-555-555-5555, your email address (for TEXT MESSAGING) would be 5555555555@messaging.sprintpcs.com.

When using AT&T cellular service, the text messaging email address for your phone is your 10-digit phone number followed by @txt.att.net. For example, if your phone number is 1-555-5555555, your email address (for TEXT MESSAGING) would be 5555555555@txt.att.net.

Example: 5555555555@VTEXT.com, 5555555555@messaging. sprintpcs.com, or 5555555555@txt.att.net would be programmed into the WCC III System parameters screen as an Email address. Any alarm type level that is generated would be sent to that cellular telephone number as a text message.

3. Network outages should be less frequent, due to the fact that there is no overhead of a pre-existing internal computer network. A pre-existing internal computer network will always require periodic “downing of the network servers” to do maintenance work to the existing computer network regardless of having the WCC III-MCD connected to the pre-existing internal computer network.

4. The need for having an onsite IT person to setup, and then administer the WCC III-MCD will be reduced.

5. Setup and maintenance of e-mail accounts would be easier, because they would be automatically provided by the Internet Service Provider.

RS-485 Communication Wiring

The WCC III System RS-485 Communication Wiring

The WCC III - MCD can communicate with up to 239 satellite controllers via a two-wire RS-485 communication loop. On the back of the WCC III – MCD there are two RS-485 communication loop ports that come as standard. Each one of these communications loop ports can communicate with up to 60 satellites for a total of 120 satellites.

Two more additional RS-485 communication loop ports can be added at an additional cost for any WCC III system that has more than 120 satellites. The two-wire RS-485 communication loop should be stranded 2 wire twisted pair of 18-gauge wire with a shield wire, and it also must be plenum rated were applicable.

The use of stranded wire is mandatory to ensure a good connection with the ¼ inch Sta-Con connectors which are used to terminate the wires at the satellite controllers. The RS-485 communication wire does not have to be run from each satellite controller back to the WCC III – MCD, but rather the RS-485 communication wire can be “daisy-chained,” which means that only one twisted pair of wires is connected to each of the WCC III - MCD communications loops. The maximum allowable length of wire from the WCC III - MCD to the farthest satellite is 4000 feet per RS-485 communications loop.

The RS-485 wire speciﬁ cations are generally a stranded 18- gauge - 2 wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection with the ¼ inch Sta-Con connectors, which are used to terminate the wires at the WCC III

- MCD and at the satellite controllers. The old SAT II Manchester communications loop was supposed to have used a 2-wire twisted pair with shield, but this was not used in every installation. This old SAT II communications loop should not be used for the new SAT III communications loop. A new RS-485 communications loop should be ran to each new replacement SAT III controller. The shield wire must be used on the new SAT III controller, as it provides a “ground” reference for the RS-485 communication loop. WattMaster Controls sells two versions of 18-gauge - 2-wire twisted pair with shield communications wire— (1) WattMaster part #WR-NL-WR-18 which is marked “Network Loop” with a red stripe for rapid identiﬁ cation. This connection is intended to run from the WCC III – MCD to the SAT III, SAT 3C/D/F, SAT 3P, and then to the next SAT 3 type controllers. (2) WattMaster part # WR-LL-WG-18 which is marked “Local Loop” with a green stripe for rapid identiﬁ cation for the TUC loops that run from the SAT 3C/D/F controllers out to the TUC controllers.

“Wire Nuts” on the RS-485 communications loop should be avoided at all costs. As an alternative to the “Wire Nuts”, WattMaster Controls has a Power and Switchable RS-485 communications board, and the WattMaster part number is PL102224. This Power and Switchable RS-485 communications board can be thought of as a 24-VAC power and communication distribution system for the SAT III communications loop, and this board will aid in initial startup and future troubleshooting of the SAT III communications loop. These boards should be used on a ﬂ oor-by-ﬂ oor basis. This Power and Switchable RS-485 communications board is also available in a small metal electrical enclosure.

WCC III Technical Guide

12. WCC III INSTALLATION GUIDE

WCC III - MCD Typical System Architecture

The wire that makes up the communication loop should be shielded. Shielded cable has an aluminum jacket over the wires that could act as an “antenna” to carry away any “stray” electrical signals that could interfere with the communication process. The shield should be grounded throughout the SAT Loop.

The SAT RS-485 communication loop wires are connected to the “R” and “T” and shield terminals on the satellite controllers using ¼-inch Sta-Con connectors. Make sure the polarity is correct. That is to say, the wire connected to the “R” and “T” terminal on the MCD must be connected to the “R” and “T” terminal on the satellite controllers. If the “R” and “T” and shield wires are crossed, the WCC III system will not communicate. The shield should be connected together when the cable is cut in order to terminate the wires at the satellite controller.

The communication loop wire from the WCC III - MCD is connected to one of the “R” and one of the “T” terminals on the satellite controller, which is physically located nearest the WCC III - MCD. The other “R” and “T” terminals located on the satellite controller can be used to extend the two-wire loop to the next satellite controller, or the wires can branch off of a two-wire loop

running through the center of a building as shown in Figure 12-6.

NOTE: The shield wire must be connected at each and every

Satellite Controller also.

Satellite Controller

Mounting in an Enclosure

The satellite controllers are designed to mount in any NEMA 1 or NEMA 3 standard, six-inch deep, electrical enclosure. Typically, this is a ﬁ eld-mounted enclosure that contains transformers and any accessory items required such as a binary input board, V-Out Binary output board, control relays, etc. The best location for these satellite panels is mounted on a wall in equipment or storage areas or rooms at eye level near the controlled loads.

The satellite controllers may be ordered with or without the NEMA type enclosures. If you order the satellite controller from the factory without an enclosure, the SAT III and SAT 3C/D/F

dimensions as shown in Figure 12-13 and Figure 12-14 may be

helpful when selecting a suitable NEMA type enclosure.

The satellite controller must be mounted in an electrical enclosure. If you do not order the satellite controller with an electrical enclosure, you must provide your own electrical enclosure and then provide and then install your own fused disconnect switch, transformer, and terminal strip.

The size of the standard single SAT enclosure is designed to hold only one satellite controller (or up to two SAT 3C/D/F controllers), one fused disconnect switch, one transformer, one ﬁ lter, and one terminal strip which is normally about 15” x 15” x 6” deep with an inter panel for mounting the SAT III controller, fuse block, 100VA transformer, etc. The size of the standard dual SAT enclosure is designed to hold two satellite controllers (or up to four SAT 3C/D/F controllers), one fused disconnect switch, two transformers, two ﬁ lters, and two terminal strips is 30” x 18” x 6” deep with an inter panel for mounting the two SAT III controllers, fuse block, 100VA transformer, etc. If you install the satellite controller yourself, make sure you leave room for wires that need to be connected to the following terminals that are located on the sides of the SAT III satellite controller (minimum recommended clearance is 2 inches):

You can also have both a SAT III controller and up to two SAT 3C/D/F controllers in the same dual enclosure.

Satellite Controller Wiring

If you order the satellite controller in an enclosure, the factory will provide and install the wires from the transformer to the satellite. If you order the satellite controller separately, you must provide a NEMA panel with an inter panel, disconnect switch, transformer(s), fusing, terminal block(s), wire, crimp connectors, and then install the wires from the transformer to the satellite controller. A typical satellite controller wiring diagram is shown below:

SA T III LED Descriptions

SA T III Controller—LED Information (SS5003)

The SAT III Controller has 24 LEDs on the cover of the SAT III controller. The top 8 Status LED functions are as follows:

SAT REC - This LED will be lit when communications are being

received by the SAT III Communications Loop.

SAT XMIT - This LED will be lit when communications are being

transmitted by the SAT III Communications Loop.

HSS REC - This LED will be lit when communications are being

received from the HSS port.

HSS XMIT - This LED will be lit when communications are

being transmitted to the HSS port.

LOCAL SET - This LED will be lit when communications

with the WCC III-MCD has not occurred for at least the last two minutes. This means that the SAT III is not communicating on the SAT III communications loop. Setpoint control in the SAT III is dependent on the LOCAL SET parameters which are programmed into each control point by the user.

STATUS 1 - LED blinks every 1 second if SAT III is alive. STATUS 2 - LED blinks every 1 second during power on delay,

and then blinks every 8 seconds when watchdog is enabled.

STATUS 3 - LED blinks for every internal calculation loop

completion.

The lower 16 LEDs display the status of the 16 “H” and “C” Relay Outputs. The 16 LEDs display the status of the eight “H” and eight “C” contacts.

SA T III Connection Points

SA T III Controller — Connection Points

All of the external SAT III connection points are single tab ¼-inch Sta-Con connectors. With the exception of the “old” connection method of connecting the Binary Inputs which are 16-pin dip cable connections and the HSS EXP COMM port which is a 6-pin premade MOLEX type mini-ﬁ t cable connection.

+V Connections.

There are eight +12-VDC connections that power analog type sensors of which the ﬁ rst seven of these connections are ﬁ xed to +12VDC only. The eighth +V connector is jumper (JP1) selectable for either +12VDC, or +24VDC. This (JP1) jumper can be set to +12VDC, or +24VDC so that the voltage at the eighth +V connection point is either +12VDC or +24VDC. The +24VDC is useful when connecting 4-to-20 mA sensors that require a connection voltage greater than +12VDC. You may connect up to eight 4-to-20 mA sensors to this eight +V (+24VDC) connection point. This JP1 jumper is located under the cover of the SAT III controller, just to the right of the eighth +V connector.

A TI Connections

These eight connections are connection points for ATI #1 to ATI #8 analog inputs. ATI is the acronym for Analog Temperature Input. These eight connection points are for Analog Inputs. This is where analog type sensors are connected to the SAT III controller. The types of sensors inputs that are supported on the SAT III controllers are: 0-1V, 0-5V, 0-10V, 10K Type 3 Thermistor, 4-20mA (On both the 0-1V, and 0-5V inputs). There are also eight Analog Input selection jumpers that are located under the cover of the SAT III controller near the Analog Inputs that actually set the type input voltage ranges for each of the eight analog inputs. These Analog Input selection jumpers are labeled JO1 to JO8. JO1 corresponds to analog input #1, JO2 corresponds to analog input #2, JO3 corresponds to analog input #3, JO4 corresponds to analog input #4, JO5 corresponds to analog input #5, JO6 corresponds to analog input #6, JO7 corresponds to analog input #7, JO8 corresponds to analog input #8. Each of these Analog Input selection jumpers has four jumper options: 0-1V, 0-5V, 0-10V, and THERM. See

Figure 12-34 and 12-35 for further wiring details. See Section 3

for further programming instructions.

GND Connections

These GND connections are analog ground common connection points for all of the analog input (ATI), and analog output (VOUT) connections.

VOUT 1 to V OUT 8 Connections

These eight analog outputs are set up to provide 0 to +15 DC Volts outputs at up to 15 milli-amps per output. These outputs are typically used to drive a VFD, 0-10VDC or 2-10VDC actuator or

valve. VOUT is the acronym for Voltage Output. See Section 3 for

additional programming instructions.

H 1 to H 8 Connections

The eight “H” connection points of the SAT III controller were originally classiﬁ ed and labeled as “HEAT” contacts starting with the SAT 0, SAT I, and SAT II controllers. They do not need to be used only for “HEAT” contacts, as these contacts are general purpose relay outputs. There is a load protection device called a varistor across each of the eight “H” output connections that limit the allowable voltage to no more than 32 volts AC\DC maximum at 1 amp current draw for each contact. Attempting to switch any voltage greater than 32 Volts, or current draws of more than 1 amp per contact could and will result in damage to the SAT III controller. These “H” and “C” contact outputs are meant to control tri-state actuators, contactors, relays, solenoids, and the PI board AKA “ECC II ANALOG OUTPUT” board that WattMaster

Controls used to manufacture. See Figure 12-18 for further wiring details. See Section 3 for additional programming instructions.

COM 1 to COM 8 Connections

The COM1 connection point is a common connection point for H1 and C1 Relays. None of the COM connections are connected to any of the other seven COM connection points. A jumper cable is available to connect all of the COM connection points together. Each corresponding “H” and “C” contact are connected to a single corresponding “COM” connection point. So “H1” and “C1” are connected to “COM1”, “H2” and “C2” are connected to “COM2”,

etc. See Figure 12-18 for further wiring details.

WCC III Technical Guide

12-17

12. WCC III INSTALLATION

SA T III Connection Points

C 1 to C 8 Connections

The eight “C” connection points of the SAT III controller were originally classiﬁ ed and labeled as “COOL” contacts starting with the SAT 0, SAT I, and SAT II controllers. They do not need to be used only for “COOL” contacts, as these contacts are general purpose relay outputs. There is a load protection device called a varistor across each of the eight “COOL” output connections that limits the allowable voltage to no more than 32 volts AC\DC maximum at 1 amp current draw for each contact. Attempting to switch any voltage greater than 32 Volts, or current draws of more than 1 amp per contact could and will result in damage to the SAT III controller. These “H” and “C” contact outputs are meant to control tri-state actuators, contactors, relays, solenoids, and the PI board AKA “ECC II ANALOG OUTPUT” board that WattMaster

Controls used to manufacture. See Figure 12-18 for further wiring details. See Section 3 for additional programming instructions.

Binary Inputs

The SAT III controller has two sets of eight-position dipswitches on its front panel labeled L1 - L8 and L9 - L16. Switches L1-L8 are housed together in one dipswitch, and switches L9-L16 are housed together in another dipswitch. For the old connection method one dipswitch is removed for each Binary Input with Time Delay board, and is then replaced with a ribbon cable which connects the Binary Input with Time Delay board to the SAT III controller. The binary devices to be monitored are then wired to the terminal strip of the Binary Input with Time Delay board. The Binary Input with Time Delay board requires a 24-VAC power source. Warning you must observe polarity on the 24-VAC and GND connections of both the Binary Input with Time Delay board and the SAT III controller, as the grounds must be the same. Or, an alternative connection method to the SAT III controller is now provided by the 6-pin HSS

expansion port on the side of the SAT III controller. See Figures 12-26, 12-27, & 12-28 for further wiring details.

24V AC & GND Connection

Located on the bottom side of the SAT III controller is a 24 VAC and GND connection. This is the main power connection to the SAT III controller. Each SAT III Controller draws - 15VA. External relays and contactors are not included, but need to be considered for total VA draw. The GND connection points must be the same between all of the externally powered expansion boards and the

SAT III Controller. See Figure 12-27 for further wiring details.

SA T Communica tion Connection

These connection points are for wiring of the RS-485 communication loop. There are two “T” (Transmit) connections, two “R” (Receive) connections and two “SHIELD” connection points. There are two connection points provided for each connection for easy “daisy chaining” to the next Satellite Controller. When connecting the RS-485 wiring from SAT III to SAT III or SAT 3C/D/F, or SAT 3P controller the wiring connections are as follows: connect “R” TO “R”, “T” TO “T”, AND “SHIELD” TO “SHIELD” OR “SH”. The RS-485 wire speciﬁ cations are plenum-rated, jacketed stranded 18-gauge, 2-wire twisted pair with shield. 18-gauge stranded wire is mandatory to ensure a good connection with the ¼-inch Sta-Con connectors which are used to terminate the wires at the WCC III MCD and at the satellite controllers.

HSS EXP COMM Connection

The HSS EXP (Expansion) Port enables newer versions of the satellite expansion boards, most notably the Binary Input with Time Delay Board and V-Out RELAY Board to work without connecting the previous way (separate power and hard wiring was required). The SAT III has a single connection via the built-in HSS EXP port on the side of the SAT III. It is designed to connect and power up 5 HSS Expansion Boards. Connecting more than 5 HSS Boards is possible, but each additional board will require a 24VAC power supply.

The HSS EXP port provides power and ground, along with communications on a 6-pin pre-made MOLEX type mini-ﬁ t cable connection. This cable is made with 16-gauge wire.

Each HSS Expansion Board has an 8-position address dipswitch that is used to set up the function of the board.

The HSS EXP port can be daisy chained to the next board. The HSS cable connections allow the HSS expansion boards to be located up to 150 feet away from the SAT III Controller.

HSS connection cables are available in the following sizes: 6-inch, 12-inch, 18-inch, 3 feet, 25 feet, 40 feet, 80 feet, and 120 feet.

SA T III Addressing

Addressing (Numbering) of SA T III Controllers

The WCC III system can have up to 239 SAT III controllers. In order for the central computer to communicate properly with each individual SAT III controller, each controller must be assigned a separate number, or address. The number is assigned by placing the small dip switches on the front of the SAT III controller marked “SAT ADDRESS” in the proper position.

The address dip switches are additive; that is to say placing switches 1 and 2 in the ON position will cause the SAT III controller to be identiﬁ ed as satellite controller number 3. The SAT III controller looks at the position of these switches only when it is going through its initialization process after being powered up. Simply changing the switch positions on a SAT III controller that is currently “on-line” will not change its number. The switches need to be placed in the proper position before powering up the SAT III controller, or the SAT III must be powered down and then back up for the SAT III to “read” the new position of the switches. When placing the switches in the desired position, make sure the switch has “clicked” into place and is properly seated.

Figure 12-16: SAT III address switch loca tion

WCC III Technical Guide

12-19

12. WCC III INSTALLATION

SA T III Addressing

Care must be taken to ensure that two SAT III controllers do not have the same address. When this condition is present, the central computer does not know where to send the information, and the information that should be sent to the SAT III controller is usually lost.

You should be aware of the symptoms caused by two satellite controllers having the same number. Let’s consider a new job in which the satellite controllers have not yet been programmed and 2 SAT III controllers are named number #3. When you call up satellite controller #3 to enter data, everything will appear to be ﬁ ne. You will be able to enter data on the screens as if nothing is wrong. However, when you leave a screen and then return to the same screen, all of the data you entered will be missing. Also, if you ﬁ nish programming the analog inputs for example, and then go to the analog input summary screen to review your inputs, all of the data you have entered will be missing.

Another situation that you might encounter is adding a SAT III controller to an existing system and accidentally giving it the same number as a SAT III presently “on-line.” Again, when you begin to program the new SAT III controller, everything will appear ﬁ ne until you leave a screen or if you go to a summary screen. Only now, all of the data is usually not missing. Generally, you get parts of your data back and parts will be missing.

If you suspect you might have two SAT III controllers with the same address (number 3 for example) the best thing to do is go to the SAT III controller that you know is number 3, and remove the 2-wire RS-485 communication loop from it. Then, go back to the computer and call up satellite controller #3. If the computer can still “talk” to satellite controller #3, there is another satellite controller that is addressed #3 connected somewhere on the RS485 communication loop.

If a satellite controller was accidentally addressed #3, there will be a satellite number missing. For example, if satellite controller #7 was accidentally misaddressed to #3, satellite controller #7 will not be present. One way of telling which satellite controllers are

“on-line” is to go to the Satellite Summary Screen (see Section

3) and see which satellite controllers the computer recognizes as

being “on-line.”

If satellite controller #7 was accidentally miss-addressed #3, there would not be a satellite controller at address #7, and the computer will give a “Non-Existing” message for satellite controller #7.

Option 1, 2, and 3 Switches

Option switches 2 and 3 do nothing. But, the SAT III controller option “1” switch selects the A-to-D converter type that is on the mother board. With the switch turned OFF, the A-to-D curve is selected for the Maxim MAX147 part, and with the switch turned “ON” for the TI-ADS7844 (BB marked) the software will use the

special A-to-D curve for the TI-ADS7844 part. See Section 3 for

proper A-to-D identiﬁ cation.

BA TT ON/OFF s witc h

This switch is used to turn the Battery (Rechargeable Super cap) ON and OFF to the SRAM located inside of the SAT III processor.

Since version 2.00 of the Satellite software the non-volatile memory is now also stored in the EEPROM, instead of the SRAM, and upon power up the memory is read from the EEPROM back into the SRAM. This switch is not of any importance anymore.

Local Set Switch

When the LOCAL dipswitch is in the ON position, the SAT III controller will operate according to their predeﬁ ned user programmed “local set” setpoints. That is, if the SAT III controller was programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected.

Local Set Disable Switch

When the LOCAL SET Disable dipswitch is in the ON position, the SAT III controller will operate according to their predeﬁ ned user programmed “On” setpoints. That is, if the SAT III controller were programmed by the user to correctly operate when and if the WCC III - MCD is off-line or disconnected.

Test Switc h

The test mode is active only if the TEST dipswitch is in the ON position. The word “TEST” can be input as the binary value within the SAT III. Example of use would be if the user programmed the word “TEST” into one of the control point values in the SAT III controller to check the operation of the SAT III controller with an alternate setpoint or schedule, the user could then place the TEST switch in the ON position to make this function work with out physically having to go back to the front-end computer to change a setpoint via the computer.

SA T III Relay Outputs

The standard SAT III controller is capable of providing 16 binary (on/off) relay outputs. These 16 relay outputs are for driving pilot duty relays. There is a load protection device called a varistor across each of the 16 output connections that limits the allowable voltage to no more than 32 volts AC\DC maximum at 1.0 or 1 amp current draw for each contact.

Attempting to switch any voltage greater than 32 Volts, or current draws of more than 1.0 or 1 amp per contact could and will result in damage to the SAT III controller. These “H” and “C” contact outputs are meant to control tri-state actuators, contactors, relays, solenoids, and the PI board AKA “ECC II ANALOG OUTPUT” board that WattMaster Controls used to manufacture. These relay outputs can be programmed in three different types of modes of basic operation: Time Clock, Dual Limit, and EA Mode. See

Section 3 for further details on Satellite programming instructions.

SA T III Relay Outputs

The terminals for the binary outputs are found at the lower lefthand corner of the SAT III controller and are labeled “H”, “COM”, and “C”. The relay contact can make or break a 24-VAC or 24VDC circuit between the COM to H or COM to C terminals. The COM to H contacts are referred to as XXXK1h-K8h in the WCC III point addressing scheme, and the COM to C contacts are referred to as XXXK1c-K8c in the WCC III point addressing scheme. XXX is the Satellite address number 1 to 239, “K” stands for contact, and the numbers 1-8 stand for the channel on the SAT III controller.

Each “H” and “C” contact connection has a “COM” connection associated with it. Please note that each one of the sets of the corresponding “H” and “C” contacts are also isolated from each other. The “COM” connection means common. When wiring the control outputs, typically all of the “COM” connections are wired together, using the supplied jumper wire (PL100867). This “COM” common connection can either be connected to 24VAC / 24VDC or GROUND depending on the application.

Figure 12-19: A control output common jumper wire is provided (PL100867) for connecting the eight “COM” connections together

The pre-made control output common jumper wire is provided in the initial spare parts kit that came with the SAT III controller. This spare parts kit contains various input load resistor packs, spare fuse, and the control output common jumper. The spare parts kit is WattMaster part number PL102029.

GUIDE

The “COM” or common connection point can either be connected to 24 VAC / 24 VDC or GROUND. It is basically a point of view of turning power “on” to a device, or removing “ground” going to the device. It makes no difference, as both methods will work equally well, and really depends on the application you are trying to control.

Proportional-Integral (PI) Output Board

The Proportional-Integral (PI) Board is a separate integrated circuit board which works in conjunction with the SAT III controller to convert a pair of SAT III binary outputs to a varying DC voltage signal. When one contact on the SAT III controller closes, the voltage supplied by the PI board will ramp down at a pre-set rate. When the other SAT III contact closes, the voltage ramps up at the preset rate. When both contacts are open, the voltage supplied by the PI board will remain at its present value. The maximum DC voltage range is 0-14.5 volts, and the minimum allowable

resistance of the controlled device is 1000 ohms. See Section 3 for

further details on Satellite programming instructions.

PI Board Connection Points

The DC voltage range along with the ramp speed is set at the PI board. The ramp speed can be adjusted from 23 seconds to 38 minutes, and the maximum range is 0-14.5 volts DC.

To control a VFD drive from a SAT III controller using the Proportional-Integral board, you must use two control outputs and a circuit board (PI Board) that we no longer make. WattMaster Controls does not make the PI Output Board anymore, but Kele makes a similar circuit board that should work. It is a Tri-State-toAnalog Output circuit board (Kele Part # PWA-2T).

If only one contact closure is available to drive the PI Board, move jumper J01 on the WattMaster PI board to the B-C position and use the SAT III’s control output in the Dual Limit mode to control the PI Board. Although when using this method with the WattMaster PI Board, the DC voltages supplied by the WattMaster PI Board will either be increasing or decreasing at the set ramp speed depending on if the contact is open or closed.

The Global Analog Mode 9 Dual Ramp Screen was created to help emulate the old WattMaster PI board in software. It basically uses the control set points of two control outputs on a satellite controller to control a single analog output on a satellite controller and should be used when controlling an analog actuator or VFD that needs to

have an analog control setpoint. See Section 3 for further details on

Satellite programming instructions.

The Proportional-Integral (PI) Board connection points

All of external connections to Proportional-Integral (PI) Board connection points are non de-pluggable screw-cage type of wire clamped based terminal blocks.

24 V AC (TB1-5) & GND (TB1-6)

ANALOG OUT (TB2-1) & GND (TB2-3&4)

The “ANALOG OUT” and “GND” terminals supply the DC voltage from the PI board.

Adjust Minimum Voltage

The PI board is factory set for a minimum voltage of 0 VDC +/-

0.2 VDC. If you want a minimum voltage other than 0 VDC, you can reset it by adjusting the potentiometer (pot) labeled “R9.” The voltage between test point #3 (labeled “TP #3” on the PI board) and ground is set 300 mV lower than the desired minimum voltage. That is to say, if you want 5 VDC as the minimum voltage to be supplied between the “ANALOG OUT” and “GND” terminals, adjust pot “R9” to get 4.7 VDC between “TP #3” and “GND.”

NOTE: The minimum voltage setpoint must be lower than the

maximum voltage setpoint.

Adjust Maximum Voltage

The PI board is factory set for a maximum voltage of 14.5 VDC +/- 0.2 VDC. If you want a maximum voltage other than 14.5 VDC, you can reset it by adjusting the potentiometer (pot) labeled “R10.” The voltage between test point #2 (labeled “TP #2” on the PI board) and ground is set at 300 mV above the desired maximum voltage. That is to say, if you want a maximum voltage of 10 VDC to be supplied by the “ANALOG OUT” and “GND” terminals, adjust pot “R10” to get 10.3 VDC between “TP #2” and “GND.”

NOTE: The maximum voltage setpoint must be higher than

the minimum voltage setpoint.

The PI board requires a 24 VAC power supply which is connected to these terminals. The PI board is generally powered by the same 24 VAC transformer that powers the satellite controller. The GND connection points must be the same between the PI board and the SAT III Controller.

HEA T (TB1-1) & COM1 (TB1-2)

When 24 volts AC is supplied between the “HEAT” and “COM1” terminals, the DC voltage supplied by the PI board will start increasing at the set ramp speed.

COOL (TB1-1) & COM2 (TB1-4)

When 24 volts AC is supplied between the “COOL” and “COM2” terminals, the voltage supplied by the PI board will start decreasing at the set ramp speed.

WCC III Technical Guide

Adjust “Ramp” Speed

The ramp speed is the time it takes for the DC voltage between the “ANALOG OUT” and “GND” terminals to change from the minimum voltage to the maximum voltage and vice versa. The ramp speed is factory set at about 19 minutes. If you want a ramp speed other than 19 minutes, you can reset it by adjusting the potentiometer (pot) located at R2. When R2 is fully counterclockwise, the ramp speed is 38 minutes (+/- 10%). When R2 is fully clockwise, the ramp speed is 23 seconds (+/- 10%). As the voltage is ramping up, the small light labeled D1 will ﬂ ash and as the voltage is ramping down, the small light labeled D2 will ﬂ ash.
