ENGINE ROOM/CONDENSER/VESSEL/EVAPORATOR OPERATION

Setup Description

The following Setup Guide is meant to assist the installation

technician in making all necessary electrical power, con-

trol and communications connections to a Quantum™ HD

Unity system. This guide also provides the basic information

necessary to login and congure the system, and will aid in

troubleshooting the system should problems arise.

This Guide will help to ensure:

Wiring

• Location of incoming AC source power to all panels, main

controller and Remote I/O Panels

• Basic installation guidelines are followed.

• Location, polarity & grounding of communications wiring.

• Location of all control (I/O) wiring.

• Proper powering up of all panels.

Conguration

• Logging into the system

• Verifying communications.

• Conguring Zones

• Calibrating sensors.

• Setting up operating Setpoints.

Operation

• Setting the operating Mode.

• Verifying the data being returned to the Interface panel

from all remote panels. (Zones)

• Checking and clearing of alarms.

• Ammonia Conguration

Typical System

A system will typically include one Quantum HD Unity System

Controller to control the engine room, condensers, vessels

and evaporators along with remote I/O panels for the evapo-

rators. The I/O for the engine room, condensers and vessels

is contained in the Quantum HD Unity System Controller

enclosure.

Quantum HD Unity System Controller

Evaporator Remote I/O Panel

One remote Evaporator I/O panel can control up to 3 zones

or valve stations. Each system may have one or more Engine

Room, Vessel, Evaporator or Condenser remote I/O panels.

The Evaporator Remote I/O panel (below) does not have a

display.

Typical System Conguration

The typical Quantum HD Unity System Controller consists of

one centrally located control and I/O panel that contains the

controllers for condenser, vessel, engine room and evapora-

tor control. This panel also contains the digital and analog I/O

for condenser, vessel and engine room control.

The evaporator I/O is located in smaller remote I/O panels

that can be mounted wherever it is convenient for installation

and maintenance. Up to 10 remote evaporator I/O panels

(30 zones) are controlled by one evaporator controller.

ENGINE ROOM/CONDENSER/VESSEL/EVAPORATOR OPERATION

System Installation

Follow these basic installation rules:

• Maximum total serial communications cable distance

between the main unit controller and the very last Re-

mote Evaporator I/O Panel on any one communications

cable run is 2000 feet. It is possible to have two separate

communications cable runs depending upon the total

number of Remote I/O Panels. Keep in mind, however,

that neither of these cable runs can exceed 2000 feet in

length.

• Keep all communications wiring in a separate conduit

from control or power wiring.

• When wiring for serial communications, it is important

to ground only one end of the communications cable.

This ground will be located in the very last Remote Panel

of each communications cable run. Ground loops could

develop if the communications were to be grounded at

both ends, impairing communications between panels.

• The Main Unity controller panel is rated NEMA Type-12.

This needs to be considered when selecting a location

to install the main Quantum HD Unity System Controller

enclosure.

• Remote I/O Panels are rated for both indoor and outdoor

use. Although the need to access Remote Panels will be

rare after installation and setup, it is still advantageous

to keep them accessible for potential maintenance situa-

tions (reasonable lighting, sufcient door swing, etc.).

• Install all panels within a convenient distance of a power

source.

Wiring For AC Power

Quantum HD Unity System Controller

The incoming AC power will consist of 3 #10 AWG wires

(Hot Neutral and Ground that are fed from a 20 Amp service

minimum.

• Connect the three incoming AC wires to the terminal

screws as shown on the drawings for the Main Quantum

HD Unity System Controller enclosure.

• Proceed to the section entitled Checking the AC Power.

Remote Evaporator I/O Panels

The incoming AC power will consist of three 12 AWG wires

(hot neutral and ground) from a 15 amp service (minimum).

• Unlatch the two ¼ turn cover latches to the Interface

panel, and open the door.

• Inside the enclosure, there is a long DIN rail at the right

side of the panel. At the top of the DIN rail is a terminal

strip.

• Connect the three incoming AC wires to the terminal

screws per the remote evaporator I/O panel drawing.

• Notice that there are multiple number 2 terminals, con-

nection may be made to any of them.

Checking The AC Power

Quantum HD Unity System Controller

• Ensure the Control Power switch is in the OFF position.

• Energize the 120 Volt circuit at its source.

• Using a DVM, measure the voltage at the AC power ter-

minal strip. Ensure that you read approximately 120 VAC

between Hot and Neutral, and Hot and Ground. There

must not be voltage between Neutral and Ground.

• Once the incoming voltage has been veried, turn the

Control Power switch to ON.

• Watch the Quantum™ HD Unity controller circuitry on

the backside of the door. You should notice various LEDs

blinking or ashing.

• Watch the display on the front of the door. After a short

period of time, you should notice the display showing a

boot sequence. Various text messages will be shown as

it proceeds with the boot-up process. When nished, a

screen similar to the following image should be visible:

• If the panel has reached the point of showing the previ-

ous screen, the boot process was successful. Turn OFF

the Control Power switch, and de-energize the 120 Volt

circuit at its source.

• If the panel does not reach to the point of showing the

above screen, then troubleshooting will be required.

Refer to end of this guide entitled Troubleshooting.

Remote Evaporator I/O Panels

• The remote evaporator I/O panel can come with optional

HOA switches that can be used to manually energize

evaporator zone components. These are easily added in

the eld after startup if determined to be necessary.

• Notice in the above pictorial, there is a Red power OFF

tab, and a black power ON plunger. These items are

located on a circuit breaker for each of the two HOA

modules.

• Push each of the Red power OFF tabs down. The Black

power ON plunger should pop up. If the plunger does not

pop up, then the power was already off. Do this to both

HOA modules.

• Energize the 120 Volt circuit by switching on the control

power switch on the right side of the enclosure.

• Using a DVM, measure the voltage at the AC power ter-

minals (1, 2 and PE). Ensure that you read approximately

120 VAC between Hot and Neutral, and Hot and Ground.

There must not be voltage between Neutral and Ground.

• Above the optional HOA modules are the I/O boards.

There will be at least one Digital board (recognizable by

the plug-in I/O modules), and one Analog board. Inspect

all boards for the presence of ashing, blinking or steadi-

ly lit LED’s. If LED’s are lit on all boards, then power has

been properly applied.

• If LED’s are not lit on all boards, then refer to the section

entitled Troubleshooting.

Wiring For Communications

Quantum HD Unity System Controller

All serial communications between the condenser, vessel and

engine room control are factory wired and tested. Verify that

the Rx/TX lights for all analog and digital boards for condens-

er, vessel and engine room control are ashing.

Remote Evaporator I/O Panels

Use the following wiring procedure:

• Open the Quantum HD Unity controller door.

• At the bottom left there is a DIN rail with several termi-

nals for the Condenser, Vessel, Engine Room and Evapo-

rator serial communications. The Condenser, Vessel and

engine Room comms are already are factory wired.

• The terminals are marked by product. The Evaporator

terminals are marked as

• E -R/T 3 and E +R/T 3 for the rst 5 remote I/O panels,

and E -R/T 4 and E +R/T 4 for the second set of 5 remote

I/O panels.

• Follow the wiring diagrams for both the Evaporator I/O

panels and the Quantum HD Unity System Controller/

Evaporator Control to properly wire the serial commu-

nications observing the grounding points, wire sizes and

general serial communications daisy chaining practices

• Refer to the CONDENSER/VESSEL SYSTEM COMMUNICA-

TIONS WIRING DIAGRAM to verify dipswitch settings.
