MCT-CM

1 What is the MCT-CM?

The MCT system combines all of the features of typical loop controllers, video/chart recorders and data logging

system into a single/intuitive display device. Email (supporting SSL/TLS), SMS (text messaging), FTP,

FileWeb, DataWeb (file transfer protocols for automated data backup and web database interface) and remote

viewing/control (via Web server/VNC server) are standard with the MCT and can be accessed via LAN/WAN

using a PC, tablet or smart phone device.

Future Design Controls’ “MCT” is offered in either a 4.3”or 7” color touch screen interface with standard “Smart

Device” user interface features for multi-loop OEM control applications (up to 10 loops). All loop configuration

and runtime user access are configurable at the device with no PC software required. OEM’s have the ability

to configure runtime features (screen availability, menus, language, etc...) to easily customize the system for

their requirements. These configurations can be imported/exported to any other MCT device for setup within

minutes by the touch of a button.

In addition to a maximum of ten loops of control, the MCT-CM can also provide up to an additional 15 inputs for

process monitoring for a total of 25 process inputs. The system is provided with eight digital inputs and 8 digital

outputs standard. The MCT-CM can be expanded to a total of 16 digital inputs and 32 digital outputs. The

MCT-CM also provides the capability of accepting analog inputs for remote set point control and providing

analog outputs capable of retransmitting system variables (PV, SP or %Out) to other devices such as a chart

recorder. The 0-10Vdc or 4-20mA user selectable signals are provided through the addition of optional analog

expander cards.

Individual process controls, one for each loop in the system, provide reliable, consistent and accurate control

by distributing the process control requirements of the system among multiple processors. Each loop control

provides full auto tune functionality with high resolution, universal process inputs. When coupled with the built-

in ramping programmer, it allows for automatic, timed control of all processes and outputs of the system.

1.1 Features

The MCT digital inputs can be configured as alarm inputs with adjustable delay timers, as control inputs for

controlling automatic program operation or for direct control of the system’s digital outputs. The digital outputs

can be used as direct outputs for controlling external equipment related to the application through software

switches, called events, or be programmed to act as system alarm or status outputs. All outputs have adjustable

delay times for on, off and cycle times.

The MCT can be operated in single set point or automatic program control mode. Program entry is made easy

through the use of copy, paste and delete menu selections. Programs can be copied to the external USB

memory stick and then imported to another MCT controller eliminating the need to enter duplicate ramp/soak

programs into multiple systems. When running in program mode, the operator can place the system into hold

and change any control parameter without modifying the original program giving the operator maximum

flexibility over the controlled process.

Data logging can be enabled manually or automatically during program operation. Data backup is provided via

a USB memory stick for plug and play transfer of files to any PC and through the included FTP back-up utility.

Data file analysis tools make looking at historical data a simple task. Any control variable saved to the data file

can be plotted on the historical data chart for any time frame within the data file’s total time range.

The built in Ethernet functionality includes a Web Server to provides access to all MCT data (view only), a VNC

interface for remote control and monitoring and an NTS clock, all available via a local Intranet connection (wired

or wireless), or the World Wide Web using a standard web browser.

System access is protected with a four-level security system (user rights based), including audit trail capability

that documents all user activity and ensures data integrity by digitally signing all data files and audit trails to

meet regulatory requirements.

MCT-CM

The MCT-CM controller includes the following features:

2 Installation

All MCT components are pre-loaded with all operating software and firmware before leaving the factory so they

are ready to install when you receive them. Before beginning installation, completely read through this section

as well as the following section (3 Wiring) to gain an understanding of the entire installation process. Consider

the installation carefully. Plan the power, signal and control wiring before installing the MCT. Also consider the

cabinet space, hardware dimensions, environmental conditions and use good wiring practices to minimize

problems that may occur due to electrical interference.

2.1 Enclosure Guidelines

The MCT must be installed correctly for reliable operation. The MCT controller is designed for installation within

a suitable enclosure. Do not install the MCT outside of an enclosure. Care must be taken when locating

components to ensure that AC power wiring, contactors, starters, relays and other sources of electrical

interference are properly located to minimize their impact on the MCT control system.

Particular note should be taken to the position of variable speed drives and switching power supplies. Their

input and load cables should be screened and properly grounded to a central equipment grounding point to

prevent radiated emissions from affecting MCT operation.

2.1.1 Locating the MCT Touch Screen Interface

It is recommended that the unit be mounted within the front panel of a steel enclosure, through an appropriately

sized opening. Proper enclosure depth is required to ensure that there is adequate spacing between the rear

of the interface and the front of any high voltage devices mounted in the enclosure when the enclosure door is

closed. It is required that a minimum separation of 2” be maintained, so plan a depth to accommodate at least

4”(102mm) behind the front of the panel.

WARNING:

•To avoid potential electric shock and other hazards, all mounting and

wiring for the MCT must conform to the National Electric Code (NEC)

and other locally applicable codes.

•

Special expertise is required to install, wire, configure and operate the

MCT controller. Personnel without such expertise should not install,

wire or operate the MCT.

CAUTION:

•Prevent metal fragments and pieces of wire from dropping inside the

housing of any MCT component. If necessary, place a cover over the

components during installation and wiring. Ingress of such fragments

and chips may cause a fire hazard, damage or malfunction of the

device.

•

Do not touch the connector pins of the SD card or communication

connectors of the MCT touch screen interface to prevent electrostatic

discharge from damaging internal components.

•

Locate the MCT and all related control components away from AC

power/motor wiring and sources of direct heat output such as

transformers, heaters or large capacity resistors.
