1 What is the MCTB?
The MCTB system combines all of the features of a loop controller, high-limit control, video/chart recorder 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 MCTB and can be accessed via
LAN/WAN using a PC, tablet or smart phone device.
Future Design Controls’ “MCTB” provides a 4.3”color touch screen interface with standard “Smart Device” user
interface features for multi-loop OEM control applications. All loop configuration and runtime user access is
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 MCTB device for setup (from scratch) within minutes.
Individual, high performance board level PID loop controls (one for each loop up to a maximum of three) offer
up to four control outputs each, powerful profiling capabilities with up to three events each (nine total) and full
auto tune functionality with high resolution universal process inputs.
The MCTB also provides the ability to connect a remote, smart IO module that provides up to an additional
eight inputs for process monitoring. The inputs can be configured as any combination of thermocouple, voltage
and current, all of which can be viewed from the MCTB display as well as logged to the MCTB data file.
1.1 Features
Each of the MCTB loop control boards provide a single digital input that can be programmed as an automatic
program control input, input alarm or input status (visual loop status indication). Each loop control board also
provides up to four control outputs which can be used as PID control outputs for heat/cool, direct outputs for
controlling external equipment related to the application through software switches called events or be
programmed to act as system alarm outputs. When single or dual loop control is used, an L41 high/low limit
control can be connected, providing a single interface for all loop control and limit functions from one display.
The MCTB can be operated in single set point or automatic program control mode. Program entry is made
easy through the use of slide list selections and menu items on a single screen. Programs can be copied to
the external USB memory stick and then imported to another MCTB controller which eliminates the need to
enter duplicate programs on multiple systems.
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 MCTB
can store over a year’s worth of data on its SD memory card. 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.
The built in Ethernet functionality includes a Web Server to provides access to all MCTB 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 standard software like Microsoft’s Internet Explorer.
The MCTB provides a rich set of tools for control interaction and process monitoring. The interface provides
various loop, chart, alarm, automated program status as well as historical data, alarm log and audit trail views.
The menu driven interface eliminates screen “clutter”by providing an easy to use “Smart Device” interface for
interaction between the user and MCTB.
The MCTB protects system access 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.

2 Installation
All MCTB components are pre-loaded with all operating software and firmware before leaving the factory so it
is ready to install when you receive it. Before beginning installation, completely read through this section as
well as the following section (3. Power and Wiring) to gain an understanding of the entire installation process.
Consider the installation carefully. Plan the power, signal and control wiring before installing the MCTB. 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 MCTB must be installed correctly for reliable operation. The MCTB controller is designed for installation
within a suitable enclosure. Do not install the MCTB 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 MCTB 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 MCTB operation.
2.1.1 Locating the MCTB 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 MCTB must conform to the National Electric Code (NEC)
and other locally applicable codes.
•
Special expertise is required to install, wire, configure and operate the
MCTB controller. Personnel without such expertise should not install,
wire or operate the MCTB.
CAUTION:
•Prevent metal fragments and pieces of wire from dropping inside the
housing of any MCTB 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.
•
When handling the MCTB B42 series loop control boards, use proper
ESD (electro-static discharge) handling procedures to prevent damage
to board components.
•
Locate the MCTB 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.

MCTB
12
Proper clearance must also be maintained above, below and on both sides of the interface to allow for heat
dissipation and to facilitate mounting. A minimum of 2” is recommended. Note that additional space may be
required below and to the right of the interface (looking from rear of unit) to accommodate the communications
wiring depending upon the type of communication cables used.
2.2 Environmental Considerations
Do not subject the MCTB touch screen interface to operating temperatures below 0°C (32°F) or above 50°C
(122°F). The operating temperature for the B42 loop controls is limited from -10°C (14°F) to 50°C (122°F).
Minimum and maximum relative humidity levels are limited between 10% and 90% (non-condensing) for the
touch screen and 0 to 90% for the loop controls. The MCTB touch screen interface is to be used indoors only.
The unit should not be installed where fast temperature variations may occur as this can cause condensation
of water vapor on the device.
The MCTB should not be exposed to excessive dust, dirt, salt, direct sunlight or shock and vibration. Do not
operate the MCTB controller in an area where chemicals or flammable gases are present. Permitted storage
temperature extremes for the MCTB control system are limited to -10°C (14°F) and 60°C (140°F) for the touch
screen and -40°C (-40°F) and 60°C (140°F) for the loop controls.
2.3 Mounting Dimensions
The quantities of certain components vary depending upon the application and options ordered. Make sure
that you have all components required for your application prior to installation. The 4.3” touch screen interface
is supplied with four mounting brackets and the 7” touch screen interface is supplied with six.
All brackets must be installed and properly tightened to insure the IP65 protective rating. Failure to install all
mounting brackets may also affect touch screen operation. DO NOT over tighten the mounting brackets. The
brackets should be tightened just enough to fully compress the gasket so that the bezel is parallel with the
mounting surface. The maximum torque used should be applied evenly on all sides and not exceed 1N-m (8.9
in lb) to prevent the LCD panel from flexing.

2.3.3 MCTB Process Loop/Limit Controls
One PID loop control is required for each process control loop in the system. The MCTB is compatible with the
Future Design Controls B42 board level control. Refer to the FDC B42 manual for dimensions, appropriate
mounting and installation instructions.
The MCTB also provides for the connection and interface to a single Future Design Controls L41 limit control.
Refer to the FDC L41 manual for dimensions, appropriate mounting and installation instructions. Use care in
determining the proper location of the limit control. Operator access to the L41 should be restricted in order to
prevent accidental or unwarranted changes to limit control settings in order to maintain all aspects of safety that
the limit control is intended to provide.
2.4 Smart IO Monitor Module
The Smart series SIO-8AIU(-H) remote I/O module provides the option of adding eight monitor input points to
the MCTB. Each input is individually configurable for an array of different thermocouple, voltage and current
types. The stand-alone module provides a wide input power range of 10-60VDC and an operating temperature
range of -25 to 70°C (-13 to 158°F). Humidity limitations range from 5 to 95% non-condensing.

MCTB

2.5 Expansion IO Module
The expansion I/O module (FDC630TA-DC) provides the option of adding an additional 16 digital inputs and
14 digital outputs to the MCTB. The inputs and outputs can be utilized as alarms, events, or for any number of
uses within math/logic functions. The expansion IO module operates on 24VDC power and within an operating
temperature range of -30 to 75°C (-22 to 167°F). Humidity limitations range from 10 to 90% non-condensing.
The inputs have a voltage range of 20-28VDC (24VDC nominal). The outputs are transistor (NPN) with an
operating range of 5-30VDC with maximum of 0.15A per output (10mA minimum).
NOTE: The MCTB supports a maximum of 9 program events and 16 total system events. Any combination
of loop outputs and expansion module outputs can be configured as program/manual only events up
to the maximums noted. All outputs can be utilized as math/logic only outputs.

3 Wiring
This section describes the methods and precautions for wiring the MCTB system components.
3.1 Power Requirements
The MCTB control system touch screen operates on a nominal 24VDC supply voltage with an allowable range
of 11 to 36VDC. The B42 loop controls can be ordered to operate from either a DC (11-26VDC) or an AC (90-
250VAC) supply. Do not power the MCTB controller components and highly inductive DC loads or input circuitry
to other equipment with the same DC power supply used for the MCTB.
If the MCTB is installed in an area with poor power quality or frequent power interruptions, it is recommended
that a time delay-on relay be installed in the power supply wiring to all components of the MCTB. This will
prevent rapid on-off cycling of the MCTB during brown-out or momentary power interruptions. Rapid power
cycling to MCTB can cause damage to the electronics and/or loss of data.
3.1.1 Installing the Power-On Delay Relay
Due to the rate at which AC/DC power supplies reach their nominal supply voltage after application of power,
the relay contact of the timer should be installed between the output of the power supply and the power input
of the MCTB control system components. This allows the power supply output voltage to reach its nominal
value prior to connecting the MCTB to its output terminals.
WARNING:
•Turn off power to the MCTB before starting installation, removal, wiring,
maintenance and inspection of the MCTB controller. Failure to turn off
power may cause electric shock, create a fire hazard or cause damage
to the MCTB.
•Emergency stop and interlocking circuits MUST
be configured outside
of the MCTB control system. If such circuits are made through the
MCTB, failure of the MCTB control system may cause uncontrollable
operation, damage to equipment or accidents.
CAUTION:
•This section presents recommended installation practices and
procedures. Since no two applications are identical, these
recommendations should be considered as guidelines. The system
designer should be aware that devices in control systems could fail and
thereby create an unsafe condition.
•
Electrical interference in an operator interface can lead to equipment
start-up, which could result in property damage and/or physical injury
to the equipment operator.
If the application requires an operator or attendant, you should be
aware that this potential safety hazard exists and take appropriate
precautions. Consult NEMA ICS 3-304 for more information regarding
safety for the installation of solid-state programmable control devices.

MCTB
18
In order to properly sense the loss of power, the time delay relay coil should be wired to the AC power source
for the DC power supply of the MCTB. This will ensure that the MCTB is turned off/on at the proper times and
prevent malfunction that can be caused by rising or falling voltage at the power supply output during power
interruption.
NOTE: It is recommended that the time delay-on relay be set for a minimum period of 3 seconds.

MCTB
19
3.2 Connecting to the MCTB Interface
Power wiring lengths should be kept to a minimum, and it is preferable to have the power wiring run using a
minimum of 18/2 twisted shielded cable. This keeps the “hot”and “common”wires paired to minimize the
effects of external noise.
To make a connection, strip about ¼” of insulation off the end of the wire, turn the connector screw
counterclockwise until the gap is wide open, insert the wire all the way in, and turn the screw clockwise until it’s
tight. Connect positive DC line (hot) to the ‘+’ terminal and the negative DC line (common) to the ‘-’terminal.
The other end of the cable should be properly terminated at the 24VDC power source, and the shield connected
to the main earth ground.
NOTE: Upon application of power, if the display does not come on within 2 seconds, remove power. The
interface is reverse polarity protected. Check wiring to ensure proper connections and try to power
up again. An Internal fuse will prevent damage for over voltage conditions; however, it isn’t
guaranteed. DC voltage sources should provide proper isolation from main AC power and similar
hazards.

MCTB

3.2.1 Process Loop/Limit Controller Communications
The loop/limit controls communicate with the MCTB touch screen using the RS485 communications port. This
allows up to three B42 boards (or two B42 boards and one L41 limit control) to be connected using one 2-wire
link. The controllers are wired in parallel with each one having their own communications address of 1, 2 and
3 (corresponding to loops 1, 2 and 3 or loops 1, 2 and L41 limit).
Communication wiring should be run using a minimum of 24 AWG twisted-pair, copper conductors. For short
runs (< 10 feet total), non-shielded wiring can be used as long as proper separation from power/control
conductors is maintained. For communications wiring where the total length will exceed 10 feet, shielded
twisted-pair should be used.
NOTE: It is important to keep the power/control and sensor/communications wiring separated from one
another. Relay and/or high voltage outputs can interfere with the sensor and communication wiring
as they cycle on and off, which can cause erroneous sensor readings or communications errors.
FDC recommends the use of shielded wire for all installations in order to maintain optimum
performance and minimize the possibility of communications errors.
When using shielded twisted-pair, be sure to ground only one end of the cable, preferably at the loop controller.
Allowing any other portion of the cable shield to come in contact with ground, or grounding both ends, will cause
ground loop currents to flow in that section of the cable shield which can disrupt communications.
