Chapter - 1. Introduction to Magnum

Magnum V17.0 software has been designed to control many different types of compressors of both fixed and vari-
able capacity, as well as many additional features. Supported control options include multiple liquid line solenoids,
electronic expansion valves (EXVs), liquid injection, economizers, hot gas bypass, variable frequency drives (VFDs),
digital scrolls, and many more.
Applications vary from control of a single compressor to complex multiple compressor systems. In all applications,
however, safety and operating efficiency is of primary importance. The controller interface is made to be informative
and meaningful, with built-in logic to prevent unsafe operating conditions from occurring. This helps reduce or even
completely eliminate nuisance alarms.

1.1. Magnum V17 Software Control Point Capacity

Circuits (compressors): Up to 20
Steps per circuit:: Up to 4
Relay Outputs: Up to 80
Analog Outputs: Up to 20
Sensor Inputs: Up to 112
Setpoints: 255
Alarm Memory: 100
Magnum Hardware Supported by Magnum V17.0 Software
The following MCS boards can be connected together through the MCS-I/O communications terminal block:
MCS-Magnum (10 RO’s, 12 SI’s, 4 Digital SI’s, and 4 AO’s)
MCS-RO10 (10 RO)
MCS-SI16-AO4 (16 SI and 4 AO)

The versatility of the Magnum offers the user much flexibility in configuring the controls in an economical way. The
limitation is not the number of boards but the total number of points.

1.2. About the Magnum

The Magnum is a rugged microprocessor controller designed for the harsh environment of the HVAC/R industry. It is
designed to provide primary control without needing mechanical controls. It will interface locally with a null modem
serial cable, remotely through an Ethernet connection, and also through building management systems. The Magnum
offers a great deal of flexibility with adjustable setpoints and control options that can be set prior to activating a system
or even when the unit is operational. The Magnum is designed to safeguard the system being controlled, minimize the
need for manual intervention, and to provide a simple but meaningful user interface.

Additional information on the MCS-MAGNUM and related products can be found in a presentation
available on our web site at:

Chapter - 3. PC Support Software for Magnum

MCS-Connect provides both local and remote communications to the Magnum independent of software type. Local
communications can be either through an RS485 or Ethernet connection. This program displays the status of the con-
troller, and changes can be made to the system with proper authorization. Configuration files can be transmitted to or
received from a Magnum unit. The Magnum automatically performs history logging and this program allows the data
to be presented in a useful graph form. A manual created in a PDF format is available on our web site:
www.mcscontrols.com, or available in other formats upon request.

3.1. Requirements for PC Software

To install and run the program we suggest the following system requirements:

Minimum System Required to Run Program

■■ PC with a Pentium-class processor
■■ Windows 7 or later operating system or
■■ Linux operating system
■■ Minimum 1GB of RAM
■■ Minimum 4GB Drive
■■ 14.4k baud modem or higher for remote
■■ Communications
■■ 1280 x 800 pixel or higher display

Chapter - 4. Network - RS-485 Connection

The next few pages show recommended network setups for communication to your controller using products from
MCS.

4.1. MCS 485 Network

The MCS 485 Network can support up to 20 Magnums and their associated I/O boards. Access to this network can be
remotely through a 14.4K Baud modem. When using the dialup connection through a modem there is no degradation
in the performance of the network.
Each Magnum in the network must be assigned a unique address in the configuration file. This address will be the
key in establishing communications with the appropriate Magnum system. It can be viewed or changed from the LCD
/ keypad of the unit with Factory authorization.
RS485 transmissions should not exceed 1 mile without a repeater.

Chapter - 8. Preparing to Upgrade an Existing Chiller

8.1. Step 1- Open MCS Supplied Upgrade Kit

(Usually fits in a 16” x 16” x 16” box)
„„ Verify Packing list of all MCS parts
„„ Obtain Spiral Binder (Divided in up to 4 sections):
• Getting Started Manual
• MCS-Config printout (Inputs, outputs, setpoints, etc.)
• Drawings of each MCS printed circuit board with
wiring connections
• Specification sheet for each MCS part
MCS-MAGNUM

8.2. Step 2- Plan to Mount New Microprocessor

„„ Keypad / Display
• Chiller Installed Outside- You should use a Panel mount which you install inside the existing rain
proof enclosure.
• Chiller Installed Inside- You should use a Door mount with a Template for mounting
„„ Mount electronics in dry location.
Keypad-Panel „„ Do not mount in enclosure with Frequency Drive or High Voltage.
Mount
„„ Avoid mounting in front of or close to High Voltage Contactors.
„„ High Voltage wiring should be run separate from Low Voltage wiring.
„„ All wiring to Analog Sensors must be with shielded cable.
„„ When running shielded cable in areas with high voltage avoid running parallel. (Run perpendicular)
„„ Allow adequate space on all sides of MCS boards to run cables and plug in communication cables.
„„ If at all possible, avoid splicing shielded cable. If a splice is required please do the following:
• Splice in an area where no high voltage is within three (3) feet.
Keypad-Door
Mount • Splice in a dry area.
• Splice all wires including Drain wire with butt connectors or solder. (Foil shield need not be
connected. Tape connections.) Stagger where butt connectors are made to avoid bulky connections.

GROUND CONNECTIONS
„„ It is important to provide a good earth ground to the 120 VAC power input to the printed circuit boards.
„„ Do not jumper the ground connections to MCS boards. Each printed MCS board should have its
ground wired directly to ground with a wire made as short as possible (12AWG).

8.3. Step 3- Prepare to Start the Unit

„„ Relay Output Check - Once the microprocessor has been completely wired a dry test of the wiring
should be done. To accomplish this use the following procedure:
• Keep main power to compressors off. Keep high voltage breakers off or pull fuses to compressors.
• Turn on 120 VAC control power.
• Get authorized on the MCS-Magnum controller. (via the keypad or MCS-Connect.)
• Put each Relay Output in ‘MANUAL ON’ and verify the appropriate contractor or solenoid turns
on. When testing the wiring to a Liquid Line Solenoid be careful not to leave it on too long if the
system uses an expansion valve.)
• Place each digital Sensor Input in ‘MANUAL ON’ to verify the correct value.
• Verify all Analog Sensors are within reasonable tolerances.
11
MCS-Getting Started Manual REVISION 3.0

• Remove the Packard connector from each pressure transducer. Verify the computer reads
-99.9P on the correct sensor.
• Calibrate pressure transducer offsets.
• If you have any Analog Outputs verify they are correct. Manually set analog values to 0%, 50%,
and 100%.
„„ After testing all Outputs and Inputs, make sure all RO’s, SI’s and AO’s are in ‘AUTO’ mode.
„„ Through the keypad, clear alarms and point information under ‘Service Diagnostics’ with factory
authorization.
„„ If any compressor is in Lockout, perform a Lockout Reset to clear.
„„ All setpoints should be displayed on the MCS-Magnum and reviewed for correctness. Specific attention
should be paid to the following Setpoints:
• Verify / set ‘Full Load Amps’
• Verify / set ‘Target’ (supply air / leaving liquid)
• ‘Low Suction, Freeze’.
• ‘High Disc’ based on water or air-cooled
• ‘Condenser‘ setpoints
„„ You are now ready to turn on main power.
„„ Once main power is ON verify the following:
• All Relay Outputs are in ‘AUTO’. (Not ’Lockout’)
• Flow switch is ‘ON’ or ‘YES’.
• RUN/STOP is in ‘RUN’.
• Assuming additional capacity is required the control state should go to ‘LOADING’. Once the
delay has reached zero the lead compressor will turn on. (If a screw with oil, then the oil pump
will come on first)
• When the compressor comes on the LLS should open. (There may be a pre-pump out to eliminate
liquid from reaching the compressor for direct expansion systems.)
• Watch suction, discharge, amps etc. to verify the unit is running normally.
• For screw compressors: Verify if the load and unload pulse timing setpoints need adjusting.
• The pulse should allow the slide to move so the amps are moving but not overshooting the target.
You may need to also adjust the amp deadband setpoints if the system seems to hunt. (Amp
deadband should be about 3-4% of FLA).
„„ Fine-tuning should now be done. (ROC, step delay, control zone, etc.)

Chapter - 9. MCS-CONNECT
MCS-CONNECT software is part of the MCS Support System. Its purpose is to provide both local and remote
communication for MCS micro controllers either by themselves or as part of a network.
MCS-CONNECT supports the following controllers:
• MCS-MAGNUM controller
• MicroMag controller

MCS-CONNECT permits the user to monitor the status of the micro controller in real time and, with proper authorization,
changes can be made to the system. In as fast as 10 seconds configuration files can be transmitted to or received
from a MCS micro controller.

Another powerful feature of MCS-CONNECT is its ability to graph event history. Since MCS controllers automatically
perform history logging, the user can select which inputs or outputs to graph and view the results either in real time or
over a user selectable period of time.

MCS-CONNECT supports the SAVE of history data in the GRAPH function as a *.txt file. This allows the user to bring
the data up in MCS-CONNECT offline or in a spreadsheet program such as Microsoft Excel.
Updates for MCS-CONNECT can be downloaded directly from the MCS website under “Support”, PC Software.

The program is available as Microsoft Windows based software or as Linux based software.

You can find complete installation and setup for MCS-CONNECT in the manual located on the MCS web site.

MCS has over a hundred APP Notes on ‘HOW TO’ for our products. They can be found at:
http://www.mcscontrols.com/appNotes.html

Chapter - 10. Getting to know your Touchscreen

On the following pages we will acquaint you with the function and use of the MCS-TOUCHSCREEN, plus
introduce you to the graphics that we have incorporated into the design.
OEMs with additional training and the Graphic Builder, will be able to make changes to the graphics and
help manage with all the information the MCS controller has available to provide.

TOUCHSCREENS
The MCS-TOUCH-15.4 has a new Weather Proof Touchscreen interface designed to simplify user access
with the MCS-Magnum and MCS-MicroMag. MCS-Connect can be utilized to provide both graphics and
service mode access for technicians.
Information and graphics on the MCS-TOUCH are shown on high resolution (1280x800) LCD
display with LED back lighting, which guarantees long-life operation.

The high resolution screen makes it easy for the user to manage complex installations quite easily. It also
ensures that the pages can be navigated in a fast and straightforward
manner. Up to 60 MCS controllers can be connected to a MCS-TOUCH via RS485 or Ethernet.

Utilizing a gasket for an environment seal provides the MCS-TOUCH with a NEMA4 rating.
Depending on the Box Enclosure you choose, an installation can be either indoor or outdoor.
A NEMA4 Box Enclosure must be used for outdoor installation or for areas that are subject to water wash-down
or extreme harsh environments. The MCS-TOUCH temperature range is -20oC to 70oC / -4oF to 158oF.
The Magnum can be installed without the Keypad Display using the new Touchscreens.

GRAPHICS FOR TOUCHSCREENS

With the new Graphical Interface and MCS-Connect, you
now have a better view of your controller’s many functions as
shown on the screen to the right.

28.4. PROTOCOLS USING MCS-BMS-GATEWAY

The MCS-BMS-GATEWAY is a microprocessor based communication device that provides translation from BACnet IP
to LonTalk, BACnet MSTP, or Johnson Control N2.
Information that can be transmitted includes the status of control points, alarm information, digital inputs, analog
inputs or setpoints.
For more information on the MCS-BMS-GATEWAY please go to www.mcscontrols.com.

PROBLEM POTENTIAL SOLUTION

A sensor input reads -99.9 This indicates an open sensor input signal or 5 VDC problem.
Check sensor wiring for missing wire or poor connection.
Check sensor for bad sensor.
If less than 5 VDC is on the sensor 5 VDC terminal block, the problem is with
probably a shorted sensor. (A poly fuse protects the board)
Remove all sensor input terminals.
Wait about 1 min. or until 5 VDC restored at sensor input.
Connect terminals 1 at time until short reappears.
A sensor input reads +999.9 This indicates a shorted sensor input signal.
Check sensor wiring for +5VDC shorted to signal etc.
Check sensor for bad sensor.
A sensor is reading less then or This indicates the sensor needs to be calibrated. (You need to have a valid Au-
greater than 3% off thorization code to change sensor offsets)
Press Service Diagnostics, press until LCD display s sensor offset option
Press enter, 1st SI# and offset appears (i.e. Suction 1 = 0.0)
Scroll using “increase (+)/decrease (-)” keys to find sensor to be calibrated
Press enter, use the “increase (+)/decrease (-)” keys to change the calibration
value. When value is correct, press enter.
LCD blank or flashing. Indicates bad connection.
Check wiring to keypad
Could indicate bad software transfer, retransmitting may be necessary.
Lost I/O Indicates communications problem.
Verify RS485 LED blinking.
Verify termination jumper only on JP4 on the MCS-Magnum and the last I/O
board.
Verify MCS-Magnum and each I/O’s address is set correctly.
Verify wiring from the MCS-Magnum to each I/O is correct.
Check fuses/120 VAC on I/O units
Invalid reading on one sensor This indicates an input problem with 1 sensor.
