Unit Controller — General
The CICD controller is a rugged microprocessor-based
controller designed for the hostile environment of the
HVAC/R industry. It is designed to be the primary manager
of the CICD product.
The controller provides flexibility with setpoints and
control options that can be selected prior to
commissioning a system or when the unit is live and
functioning. Unit display presents pressure, temperature
and alarm information with history in a clear and simple
language format, informing the user of the chiller status.
See wiring diagram in the wiring section of this manual
("Wiring," p.
42) and attached to the inside of the control
panel door.
A password is required to access chiller setpoints. Use
password code 2112 to access many of these features. A
factory code may be required to allow access to critical
areas, and can only be entered by a factory representative.
An RS-485 port is provided for communication with other
manufacturers' systems.
Additionally, a built-in RS-485 to RS-232 converter allows
communication over the RS-485 network via the RS-232
port.
Other features include the integration of BACnet IP

MODBUS
into the unit controller. Optional
communication cards are available for communication via

be ordered with the chiller if required. An ethernet
connection is also provided on each unit. While field
changes can be made, please ensure that the unit is
ordered set up for required communications to ensure
that factory testing includes end user configuration.
A complete software support package is available for your
PC allowing for system configuration, dynamic on-line
display screens, remote communication, graphing and
more. Downloads for the MCS-Connect software are
available at www.mcscontrols.com at no charge. See
"Downloading and Installing Unit Controller (MCS-
Connect) Software," p. 33
information needed to run the unit is available from the
unit display; however, a laptop computer is invaluable for
ease of use of diagnosing or changing the unit setpoints.
Note: Not all setpoints can be changed with MCS-
Connect; some require a configuration change.
A serial cable is included in each shipment for the
convenience of the field technician. If you do not have a
laptop with a serial port, you will require a converter such
as a Black Box item number #IC199A-R3 serial-to-USB
adaptor.
The CICD standard configuration allows for the unit to start
at the lowest stage possible, and then add compressors as
needed to meet demand.

Important:
All configuration changes need to be done
by factory representatives to ensure proper
operation of the unit within design
parameters. See CG-SVX030*-EN

Software Installation and Setup
Downloading and Installing Unit
Controller (MCS-Connect) Software
Go to www.mcscontrols.com.
Go to the software page and select MCS-CONNECT. Select
SAVE. After downloading, open and select RUN. Follow
prompts and software will be installed on your computer.
If your computer does not have a serial port, you will need
to purchase a USB to Serial adapter. (Computer stores
should have this.) Install the software for the adapter. If
your computer has a serial port, you will not need an
adapter.
Start the MCS-CONNECT software. Select
SETUP>COMMUNICATIONS and then change LOCAL
COM PORT to match your computer. Select SAVE and then
and
OK.
Connecting to the Chiller
Connect the supplied NULL MODEM cable between your
USB adapter or serial port to the chiller. A standard serial
cable will not work.
Connection directly through the 100 MBPS Ethernet port
on the CICD unit controller or array controller to a PC
requires a crossover Ethernet cable. If all controllers in the
array are connected to an Ethernet switch, then an
Ethernet patch (straight) cable will be used to connect the
PC to the Ethernet switch.
Start the MCS-CONNECT software and select LOCAL
SERIAL. The site info page will appear. The software
should scan and find the chiller. (If you see a Failed to open
comm port error, or it scans and does not find the chiller,
your comm port settings are not correct.) Click the tab next
to the "Site Info" tab. The screen shows real time data.
Setpoint Changes
Click the VIEW ONLY button. Enter the password code
2112. Select OK. Button should say SERVICE. Go to
setpoints and double-click on a value. Change and select
OK.
Viewing and Troubleshooting ALARMS
The unit controller will record and store 120 seconds of
sensor input data prior to and up to any LOCKOUT ALARM.
Select the ALARM tab, then INFO next to the alarm you
