MG320-00-VAV

VAV System

Description

The MG320-00-VAV VAVBOX controller is used for controlling airflow and operation of VAV terminal units. It is a programmable digital controller, which allows for program setpoints to be stored in nonvolatile memory. The controller is connected to a room sensor via a modular cable assembly, which monitors space temperature allowing the VAVBOX controller to modulate a damper in response to space temperature, duct temperature and airflow requirements in the controlled space.

The MG320-00-VAV VAVBOX Controller has three integral modular jacks for connection to the actuator, airflow sensor (for pressure independent applications) and relay or analog expansion boards, via modular cables. A 2 wire terminal block is provided for connection of a 24VDC power transformer, a 2 wire terminal block is provided for the Room Temperature Sensor and a 3 wire terminal block is provided for connection of the communications loop. The controller has an on-board dip switch provided for board addressing.

The VAVBOX controller is provided with two relays for tri-state control of the damper actuator. The actuator connects via a modular cable to the board and provides the VAVBOX controller with feedback monitoring for precise positioning of the actuator.

Mounting

Each VAVBOX controller is provided with a plastic snap track modular mounting base. The snap track is designed to be mounted with sheet metal screws to a flat surface using the pre-punched mounting slots provided. The VAVBOX controller is then snapped into place on the snap track providing for easy field mounting and servicing.

VAV System

Description

The OE322 - 3 Relay with Analog Output Expansion board is used in conjunction with the MG320–00-VAVZ controller board to allow for control of VAV terminal units, including series and parallel fan terminal units with up to 3 stages of electric heat, SCR electric heat or with modulating hot water heat. The OE322 Analog Output Expansion board provides 3 relay outputs for pilot duty switching control, and 1 Analog output for control of a 0-10V modulating hot water valve or SCR controlled electric heating coil. The expansion board is also equipped with 24 VDC (+V and GND) output terminals for powering a 24 VDC hot water valve actuator if desired. A 24 VAC hot water valve actuator can also be used but will require the use of a separate field supplied 24 VAC transformer to power the valve actuator.

The OE322 - 3 Relay W/ Analog Output Expansion board connects to the MG320–00-VAVZ controller board by means of a modular cable provided with the OE322 board. Power is supplied to the board by means of this modular cable. Screw terminals are provided for connection of field wiring to the relay and analog outputs.

The relay outputs are N.O. contacts with one common terminal. All outputs and the relay common are electrically isolated from all other circuitry on the board. All relay outputs are supplied with transient suppression devices across each set of contacts to reduce EMI and arcing. The relay output contacts are rated for pilot duty control of a maximum of 2 Amps @ 24 VAC or 24 VDC. The analog output provides a 0 – 10 VDC modulating signal output into a 1k Ohm minimum load. The 24 VDC (+V and GND) output terminals are rated for control of a 24 VDC valve actuator with a maximum load rating of 12 Watts or less.

MG364-22– MiniLink

VAV System

Description

The MG364-22 MiniLink Polling Device is a network controller that is used to integrate multiple local communication loops into a network communications system. “Network” loop terminals on the MiniLink Polling Device are designed to be connected to the CommLink II and to other MiniLink Polling Devices on the ”Network” communications loop. “Local” loop terminals are designed to be connected to controllers installed on the “Local” communications loop.

The MiniLink Polling Device is provided with a 2 wire terminal block for connection to the required 24 VAC source(by others). It also has (2) 3 wire terminal blocks for communications wiring. One of the terminal blocks is field connected to the “Local” communications loop and the other is field connected to the “Network” communications loop.

Polling Device

The MiniLink Polling Device utilizes token passing communication architecture. The MiniLink Polling Device is designed to serve as the local communications loop master. This means that it is responsible for sending the token to all the controllers on the local communications loop. Network communications are of the RS-485 type operating at 19,200 baud. Local communications are also of the RS-485 type and operate at on systems requiring override or alarm indication. It also provides tenant-logging capabilities for the WattMaster VAV system.

VAV System

Description

The OE361 - CommLink II Communications Interface allows user ac cess to any controller connected to the controls system. The CommLink II comes packaged in an attractive beige colored plastic enclosure. The Comm Link II is powered by a small wall mounted plug-in transfor mer that is included. Locally, an optional onsite computer may be connected to the CommLink II for direct access to system control parameters. Remote access is obtained via an optional modem which is connected with the CommLink II Communication Interface. With a modem installed, the CommLink II may be configured to call a number, if an alar m condition occurs. With the modem option the system could be dialed and monitored from a remote location by a PC. Computer and modem cables (6ft long) are provided with the CommLink II.

OE361 – CommLink II

Communications Interface

Mounting

If an on-site computer is to be used for direct connection and monitoring of the system, the CommLink II should be located near the computer terminal to monitor the system. If no on-site computer is to be used, locate the Comm Link II near the phone line jack for ease of connection to a modem. If for any reason you use cables of greater length than those provided with the CommLink II (6 ft. long) be sure the cables that connect the CommLink II to the modem and the CommLink II to the on-site computer do not exceed twenty-five feet in length.
