Systems Overview

General Information

The Orion system components can be configured into several types of systems. It is a good idea to become familiar with the different types of systems and their architecture by reading the information in this section and looking at the configuration diagrams in the System Configurations Installation & Commissioning section of this manual. The information below is designed to help you understand how the system components integrate with each other and the available configuration options.

System Types

Four different system configurations are available depending on the type and number of controllers that you have on your system.

Networked Single Loop

The Networked Single Loop system, as its name implies, consists of a single communications loop. This loop utilizes a network device to share information that is broadcast from one controller to all controllers on the loop. The system can consist of the following devices.

1.

A series of VCM Controllers that utilizes a network device to share information that is broadcast from one controller to all controllers on the loop.

2.

A single VCM controller and a series of VAV/Zone controllers. A network device is used to share information which is broadcast back and forth between all controllers on the loop.

1.

Stand Alone

(See Pages 6 Through 8 For Connection Diagrams)

2.

Interconnected

(See Pages 9 Through 11 For Connection Diagrams)

3.

Networked Single Loop

(See Pages 12 Through 16 For Connection Diagrams)

4.

Networked Multiple Loop

(See Pages 17 Through 19 For Connection Diagrams)

These systems require a network device in the form of either a CommLink communications interface or a MiniLink Polling Device. Both network devices may also be used together. Programming and status monitoring are accomplished by the following methods.

1.

By using an operator interface. This can be either a

Modular System Manager, a Modular Service Tool or both devices.

2.

A computer interface can also be used in conjunction with the other operators interfaces listed above, or by itself. This requires a CommLink and a personal computer with the

Prism computer front end software installed.

System Type Definitions

Stand Alone

This system consists of a single VCM controller. Programming and status monitoring are accomplished by one or more of the following methods.

When using the MiniLink Polling Device alone, only the System Manager or Modular Service Tool can be used to program and monitor the system. With the addition of the CommLink, the Prism computer front end software and a PC can be used to program and monitor the system in addition to the Modular Service Tool or Modular System Manager.

1.

By using an operator interface. This can be either a

Modular System Manager, a Modular Service Tool or both devices.

2.

A computer interface can also be used in conjunction with the other operators interfaces listed above, or by itself. This requires a CommLink and a personal computer with the

Prism computer front end software installed.

Interconnected

This system consists of a group of VCM Controllers interconnected with communication cable to allow programming from one central location. Broadcasting between controllers is not available. Programming and status monitoring are accomplished by one or more of the following methods.

Networked Multiple Loop

This Networked Multiple Loop System consists of two or more loops, each being called ‘Local Loops’, with one ‘Network Loop’ that ties the

Wiring Considerations

Before beginning installation, please study the wiring diagrams for the controllers you are using with your particular application. These diagrams appear in this Component & System Wiring Technical Guide and can also be found in the technical guide supplied with your specific controllers. Wire and transformer sizing instructions and examples are located on page 28 through 29 of this manual.

This device is responsible for local loop broadcasts only. It always resides on the local loop.

For a Networked Single Loop VCM system, this device can be used for tenant logging and alarm reporting to a Modular System Manager. It can be used to broadcast information like outside air temperature or outside air humidity to all devices on the local loop. It can also be used to broadcast space temperature from a GPC Plus or GPC-17 controller to any controllers on this loop that do not have their own space temperature sensor.

Most of the Orion controllers are equipped with modular connections, and in some cases are equipped with both modular and wiring terminal blocks. We recommend (when possible) using modular cables instead of hard wiring to wiring terminal blocks, to save installation time and eliminate wiring errors. In some cases, however, hard wiring is unavoidable. The table below lists the various Orion devices/controllers and their available termination type(s) for communications and power wiring.

For a Networked Single Loop VAV system, the MiniLink Polling Device can be used for tenant logging and alarm reporting to a Modular

System Manager. It must be used to broadcast information such as, internal schedule, supply air temperature, fan and heat status, unoccupied calls for heating and cooling from the VAV/Zone controllers, and forced modes of operation.

For a Networked Single Loop Zoning system, this device must be used for zone voting, because it calculates the heating and cooling totals on the loop and broadcasts cooling, venting, and heating modes to the VAV controller. It can also be used for tenant logging and alarm reporting to the Modular System Manager.

CommLink

The CommLink device is used in the following applications.

1.

A CommLink is required on all Networked Multiple Loop

Systems

2.

A CommLink is optional on all Networked Single Loop

Systems

3.

A CommLink is required on any system when a computer interface is desired

The CommLink is responsible for local loop broadcasts on a Networked

Single Loop system, and on this type of system, the on board jumper must be set to “Single”. This device is responsible for network broadcasts on Networked Multiple Loop systems. On this type of system, the on board jumper must be set to “Multi”.

For a Networked Single Loop VCM system, this device can be used for tenant logging and alarm reporting to a Modular System Manager. It can also be used to broadcast information like outside air temperature or

System Installation

Power/Comm Board Requirements

Standard Connection Configurations and Use

Power/Comm boards are typically used on Networked, Single and

Multiple Loop systems to transfer 24 VAC power and “Local Loop” communications to VAV/Zone controllers, System Managers or other

Power/Comm boards.

The Power/Comm board must always be powered by its own dedicated 24 VAC transformer connected to it’s 2-wire, 24VAC input terminals (TB1).

Local Loop communications are transferred to the Power/Comm Board via a modular cable connected to its “Comm In” modular connector input terminal (P2). This modular cable connection can originate from the “Local Loop” modular connector of the MiniLink PD for this loop, another Power/Comm board output on the same loop or a VAV/Zone controller or System Manager output on the same loop. If desired a

Power/Comm board can be connected to the “Local Loop” by hard wiring a 2-wire shielded cable connected between it’s 3-wire communications input terminal (TB1) and a VCM controller, a Power/Comm board or the MiniLink PD “Local Loop”, 3-wire communications terminal.

For detailed wiring diagrams, see the Power/Comm board wiring diagrams in the “Communication Devices Diagrams” section of this manual.

For Power/Comm board transformer sizing see the last 2 pages of the

“Systems Configurations Installation & Commissioning” section of this manual.

Alternative Connection Configuration and Use

If desired, the Power/Comm board can also be used to transfer both 24

VAC power and “Network Loop” communications to multiple MiniLink

PDs. Connection between the MiniLink PD(s) and Power/Comm board(s) is accomplished by using modular cables between the Power/

Comm boards modular output connectors and the MiniLink PD(s) “Network Loop” modular input connectors. When a Power/Comm board is used to connect power and communications to MiniLink PDs in this manner, that particular Power/Comm board cannot also be used to share communications and/or power with VAV/Zone controllers or System

Manager(s).

Warning: Do not ground the 24 VAC transformer that is to be used with the Power/Comm board. Grounding of the transformer will damage the Power/Comm board and all boards connected to it. A separate transformer must be used for each Power/Comm board. No exceptions. Do not connect any other devices to the transformer used for the Power/Comm board!

For detailed wiring diagrams, see the Power/Comm board wiring diagrams in the “Communication Devices Diagrams” section of this manual.

MiniLink Polling Device (MiniLink PD)

Standard Connection Configurations Use

The MiniLink PD is used on Networked Single and Multiple Loop systems to provide two way communications between all devices on it’s “Local Loop” and to all the other “Network Loop” devices on the entire system. The MiniLink PD is equipped with both modular connectors and hard wiring terminal blocks for connection of 24 VAC power,

“Local Loop” and “Network Loop” communications.

Each MiniLink PD is normally hard wired to a 24 VAC power source connected to its 24 VAC input terminal (TB1). “Network Loop” communications are transferred between multiple MiniLink PDs by modular cables connected to their “Network Loop” modular connectors (P3 and P5). A CommLink must be connected to one of the MiniLink PDs on the system by using a 2-wire shielded cable connected between its 3wire “Network Loop” communications terminal block (TB4) and to the

CommLink’s “485 Loop” terminals block. Transfer of “Local Loop” communication from the MiniLink PD to a Power/Comm board is made by using a modular cable connected between the MiniLink PD “Local

Loop” modular connector (P4) and the Power/Comm board modular

“Comm In” connector (P2). If desired as an alternative, transfer of

“Local Loop” communication from the MiniLink PD to a Power/Comm board can be made by hard wiring a 2-wire shielded cable connected between the MiniLink PD’s 3-wire communications terminal (TB1) and the 3-wire communications input (TB1) on the Power/Comm Board.

Installation Procedures

The installation procedures that follow are based on recommended methods of wiring connection and controller installation. Installation procedures vary depending on the type of system you are installing.

Transformer & Wire Sizing - Devices Without Modular Connectors

24VAC Power - Transformer & Wire Sizing Considerations for Devices Without Modular Connectors

Some installers like to use one large 24VAC transformer to power several devices. This is allowable as long as polarity is maintained to each device on the transformer circuit.

Warning:

If polarity is not maintained, severe damage to the devices may result. WattMaster Controls recommends using a separate transformer for each device in order to eliminate the potential for damaging controllers due to incorrect polarity.

Using separate transformers also allows redundancy in case of a transformer failure. Instead of having 8 controllers inoperative because of a malfunctioning transformer you have only 1 controller off line. If the installer does decide to use a large transformer to supply power to several devices, the following transformer and wire sizing information is presented to help the installer correctly supply 24VAC power to the devices.

Following is a typical example to help the installer to correctly evaluate transformer and wiring designs.

Each GPC Plus Controller requires 8 VA @ 24VAC power. In the examples below we have a total of 8 GPC Plus Controllers.

8 GPC Plus Controllers @ 8VA each................ 8 x 8VA = 64VA.

The above calculation determines that our transformer will need to be sized for a minimum of 64VA if we are to use one transformer to power all the controllers.

Next we must determine the maximum length of run allowable for the wire gauge we wish to use in the installation. Each wire gauge below has a voltage drop per foot value we use to calculate total voltage drop.

18ga wire.................................0.00054 = voltage drop per 1’ length of wire

16ga wire.................................0.00034 = voltage drop per 1’ length of wire

14ga wire.................................0.00021 = voltage drop per 1’ length of wire

For our example we will use 18 gauge wire. WattMaster recommends 18 gauge as a minimum wire size for all power wiring.

Next use the voltage drop per foot value for 18 gauge wire from the list above and multiply by the total VA load of the 8 controllers to be installed.

0.00054 (Voltage drop per foot for 18 gauge wire) x 64VA controller load =

0.0346

Volts/Ft.

WattMaster controllers will operate efficiently with a voltage drop no greater than 2 Volts. Divide the total allowable voltage drop of 2 Volts by the number you arrived at above and you have the maximum number of feet you can run the 18 gauge wire with an 75 VA transformer with no more than a

2 Volt drop at the farthest controller from the transformer..

2 (Volts total allowable voltage drop)

= 57.80

feet

0.0346 (Voltage drop per 1 ft. @ 64VA load)

Parallel circuiting of the wiring instead of wiring all 8 controllers in series allows for longer wire runs to be used with the same size wire (as shown in our examples below).

It is often necessary for the installer to calculate and weigh the cost and installation advantages and disadvantages of wire size, transformer size, multiple transformers, circuiting, etc., when laying out an installation. No matter what layout scheme is decided upon, it is mandatory that the farthest controller on the circuit is supplied with a minimum of 22 Volts.

Transformer Sizing & Cabling - Devices With Modular Connectors

24VAC Power - Transformer & Cabling Considerations for Devices With Modular Connectors

Modular devices include the VAV/Zone Controller, Modular

System Manager & MiniLink Polling Device. When sizing transformers for the devices it is important to design your layout so that the fewest number of Power/Comm distribution boards and the least number of transformers can be used.

The polarity problem discussed in regards to other devices that do not have modular connections is not an issue with the modular devices as they cannot be connected with reversed polarity because of the modular board connectors and cable.

Also the prefabricated cable is always 16 gauge. Wire size selection is therefore not an issue with the modular devices.

However, the same minimum voltage rules apply to modular devices as with other non-modular devices. In order to simplify wiring design and layout with modular devices the following rules apply:

Power/Comm Board maximum transformer size = 100VA.

This is due to the board circuitry and fusing. Each modular device is to be calculated at 6VA. This allows for a maximum of 16 devices per Power/Commboard. If more than 16 devices are required, multiple Power/Comm boards must be used.

No more than 6 modular devices allowed per branch circuit.

(The Power/Comm board has a total of 4 branch circuits)

The longest total run per branch circuit is 240 Ft. This is due to voltage drop on the prefabricated cable.

Below are some examples of transformer sizing and branch circuit design.

6 Devices Maximum Per Branch Circuit

16 Devices At 6 VA = 96 VA

Use 100 VA Transformer

WARNING!

Be sure the chip you have selected to replace is a socketed chip. Not all driver chips on the boards are field replaceable. Only socketed chips may be removed and replaced in the field. All other chips that are not socketed will require sending the board to the WattMaster factory for repair.

If you try to remove a chip that is not socketed it will destroy the circuit board.

Once you have determined that the chip needing replacement is indeed a socketed chip please proceed in the following manner.

Remove the communications loop connector and then the 24VAC power connector on the controller before attempting to change any components.

DAMAGE

will occur if components are removed or installed with power applied.

If you are unsure how to safely remove the chip or about the correct pin placement, please consult the factory before proceeding.

Damage to the board caused by failure to correctly remove or install the chip is not covered by the

WattMaster warranty.

Use extreme care to avoid inserting the screwdriver or I.C. Puller under the socket. You must insert the tip of the screwdriver or ends of the I.C. Puller between the body of the chip and the chip socket.

Each chip

MUST

be installed with Pin 1 in the correct location. Installing the chip “backwards” will in most cases destroy the device when power is reapplied.

Pin 1 can be located by looking for the notch in the end of the chip. Pin 1 on "some" chips is identified with a dot.

Be certain that

ALL

pins are lined up in the socket before pressing the chip in. Failure to properly line up the pins will result in damage to the chip.

This is a

VERY

common error -

BE CAREFUL.

Only after confirming that the chip has been correctly installed with Pin 1 in the proper position and that the pins are lined up and none are bent or out of the socket, should communication or power wiring be reconnected to the board. Tp prevent possible damage always reconnect the power wiring first and then the communication wiring.

Thermistor Sensor Testing Instructions

Use the resistance column to check the thermistor sensor while disconnected from the controllers (not powered). Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DC volts. Place the “-”(minus) lead on GND terminal and the “+”(plus) lead on the sensor input terminal being investigated.

If the voltage is above 5.08 VDC, then the sensor or wiring is “open.”

If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.
