MCT-MC 4.3
1 What is the MCT-MC?
The MCT-MC system combines all of the features of a loop controller, 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 MC and can be accessed via LAN/WAN
using a PC, tablet or smart phone device.
Future Design Controls’ “MC” 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 MC device for setup (from scratch) within minutes.
Individual high performance board level PID loop controls (one for each loop up to a maximum of 10) offer up
to four control outputs each, powerful profiling capabilities with up to three events and full auto tune functionality
with high resolution universal process inputs.
1.1 Features
Each of the MC 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 of the loop control boards also provide 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.
The MC can be operated in single set point or automatic program control mode. Program entry is made easy
through the use slide list selections and menu items on a single entry screen. Programs can be copied to the
external USB memory stick and then imported to another MC 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 built in Ethernet functionality includes a Web Server to provides access to all MC 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 MC 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 MC.
The MC can store over a years 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 MC 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 MC 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 W iring) to gain an understanding of the entire installation process.
Consider the installation carefully. Plan the power, signal and control wiring before installing the MC. Also
consider the cabinet space, hardware dimensions, environmental conditions and use good wiring practices to
minimize problems that may occur due to electrical interference.
To avoid potential electric shock and other hazards, all mounting and

power/motor wiring and sources of direct heat output such as
transformers, heaters or large capacity resistors.
The MC must be installed correctly for reliable operation. The MC controller is designed for installation within
a suitable enclosure. Do not install the MC 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 MC 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 MC operation.
2.1.1 Locating the MC 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 insure 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.
Installation - 9 - FDC MCT-MC
MCT-MC 4.3
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 MC touch screen interface to operating temperatures below 0°C (32°F) or above 50°C
(122°F). The operating temperature for the P41/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 MC 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 MC should not be exposed to excessive dust, dirt, salt, direct sunlight or shock and vibration. Do not
operate the MC controller in an area where chemicals or flammable gases are present. Permitted storage
temperature extremes for the MC 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
Note that your system may not include some of these components, and that 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.
2.3.1 MC Touch Screen Interface
The MC 4.3 interface is supplied with four mounting clips. All four clips must be installed and properly tightened
to insure the IP65 protective rating. Failure to install all mounting clips may also affect touch screen operation.
Be sure to tighten each one evenly so as not to flex the case of the unit. DO NOT over tighten the mounting
clips. The clips should be tightened just enough to fully compress the gasket so that the bezel around the
interface is parallel with the mounting surface.
Mounting Clip Slot (4 total) Mounting Clip Installed in Slot
NOTE: The MC will not operate properly without the SD card installed into the SD card slot on the back of
the unit. The SD card has all software required, loaded onto the card for ‘Auto-Boot’ operation. The
slot on the back of the interface is ‘keyed’ so the card can only be installed in one direction. The card
is pre-installed for your convenience. If the card is removed, take care when inserting the SD card
and DO NOT force it into the slot. The card MUST be installed prior to application of power.

2.3.2 MC Process Loop Controls
One PID loop control is required for each process control loop in the system. The MC is compatible with both
the Future Design Controls P41, ¼ DIN control and the B42 board level control. Refer to the FDC controller
manual for the model of loop control being used for dimensions, appropriate mounting and installation
instructions.
For applications requiring frequent access to the process controllers, the panel mounted P41 series provides
direct access to the controllers. For applications where operator access to the controls is not required, or is
desired to be kept at a minimum, the B42 loop controls can be mounted directly inside of an enclosure. This
also reduces wiring concerns by eliminating the need to run the sensor, communication and control wiring for
each control to and from an enclosure door.
NOTE: The MC requires firmware version V.22 or later in the P41/B42 loop control for proper manual event
operation. Early model controls can be used, but the manual event control will not function. Only
automatic ramp/soak program event control will be available.

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.
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.
3.1 Power Requirements
The MC control system touch screen operates on a nominal 24Vdc supply voltage with an allowable range of
11 to 36Vdc. The P41/B42 loop controls can be ordered to operate from either a DC (11-26Vdc) or an AC (90250Vac) supply. Do not power the MC controller components and highly inductive DC loads or input circuitry
to other equipment with the same DC power supply used for the MC.
If the MC 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 MC. This will prevent
rapid on-off cycling of the MC during brown-out or momentary power interruptions. Rapid power cycling to MC
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 MC control system components. This allows the power supply output voltage to reach its nominal value
prior to connecting the MC to its output terminals.
Wiring - 13 - FDC MCT-MC
MCT-MC 4.3
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 MC. This will insure that the MC 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.
FDC MCT-MC - 14 - Wiring
MCT-MC 4.3
3.2 Connecting to the MCT-MC 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 insure 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.
Wiring - 15 - FDC MCT-MC
MCT-MC 4.3
3.2.1 Process Loop Controller Communications
The loop controls communicate with the MC touch screen using the RS485 communications port. This allows
up to ten P41/B42 boards to be connected using one 2-wire link. The controllers are wired in parallel with each
one having their own communications address of 1 through 10 (corresponding to loops 1 through 10).
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.
FDC MCT-MC - 16 - Wiring
MCT-MC 4.3
3.2.2 Connecting to the Process Loop Controls
The MC is compatible with both the Future Design Controls P41, ¼ DIN control and B42 board level process
loop controls. The input and output wiring to the individual loop(s) is dependant upon options ordered on each
device as well as the intended application. For detailed information on input and output wiring, refer to the user
manual for the type of control used.
3.2.3 User Serial Communications
The MC touch screen provides an RS232C user communications port for connecting the MC to a PC running
software such as Future Design Control’s Envision software. In order to connect the MC to a PC, a cable must
be fashioned according to the diagram below.
NOTE: DO NOT use a standard null-modem cable to connect the MC to a PC. Most computers do not
provide a standard serial port and a USB to serial converter must be used. Incompatibilities may exist
between the MC and certain USB to serial adapters which may cause the MC to malfunction when
connected using a standard null-modem cable.
If more than one MC controller is to be placed on the communication link with a PC, an RS232/485 converter
is required for each MC in order to convert the RS232 communications port to a RS485 multi-drop
communications for connecting multiple MC controls on the same PC communications link.
Wiring - 17 - FDC MCT-MC
MCT-MC 4.3
NOTE: The connection requires a single twisted-pair cable that is daisy-chained from one MC to the next.
When using shielded twisted-pair cable, be sure to ground only one end of the cable, preferably at the
RS232 to RS485 network adapter. 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
which can cause communication errors.

4 Configuring the MCT-MC
IMPORTANT: Once all configuration settings are made, you must select “Exit” from the File menu to exit the
Cconfigurator prior to cycling power to the MC. All configuration files are written upon exiting
the Configurator. Do not cycle power prior to exiting the Configurator or settings will be lost
and the MC will not operate properly once the runtime application starts.
The MC Configurator is a powerful tool that is built in to the system. It is a program that allows the OEM or user
to set up control system options for the MC runtime application. This allows for on-the-spot setup of the MC
without the need for external hardware and software. The user or OEM must first run the Configurator prior to
putting the MC into service in order to properly setup the system for its intended use.
The Configurator program does not run at the same time as the main runtime software. It can be run by exiting
the runtime software via the Offline Setup\Exit Application screen. When the “Exit application (configuration
mode startup)” option is selected, on the next power-up, the Configurator application will automatically start.
From the Configurator, the user or OEM can then setup all process loop controls as well as choose from a long
list of standard features to provide in the runtime application. During setup, the output control functions of each
device can be changed, so any equipment being controlled by the outputs should be placed in an “off” state, so
that any modifications to output functions will not cause an unsafe condition or damage to equipment.
NOTE: On exit of the MC Configurator application, the MC runtime application will automatically run on the
next power-up.
The MC Configurator provides the following functionality:
Set the number of control loops that the system will use (one to ten).
Provide control loop configuration settings for input type, output function, set point range, etc.
‘Splash Screen’ name editing for custom OEM or user requirements
Enable/disable options for runtime menu and screen availability
Text editing for all system event and alarm names
The Configurator menu is accessed by pressing the “Monitor” icon at the top left of the screen.
Configuring the MCT-MC - 19 - FDC MCT-MC
MCT-MC 4.3
The File menu provides selections of “Exit” and “About”. The exit
function for the Configurator saves all settings and closes the
Configurator application.
The about selection displays version information for the
Configurator application and configured control devices.
The Setup menu provides access to the primary controller setup
options. These options include the controller setup (number of
loops), the loop control board configuration settings and the loop
address utility that can be used to automatically assign the
proper communications address to an attached loop control
board.
The Startup menu provides access to enable and disable
runtime screens/menus and set the desired startup view
selection.
The Tagnames menu provides access to the text editing
functions of the Configurator which allow the event and alarm
names to be changed to match their use in the system. The
menu also provides access to edit the splash screen information
that is shown when the runtime application starts.
FDC MCT-MC - 20 - Configuring the MCT-MC
MCT-MC 4.3
4.1 Control Setup
The “Control Setup” screen is accessed from the Setup menu. It allows the user or OEM to set the number of
control boards that are attached to the system. Once set, the loop configuration settings will be made available
for the total number of loops entered.
4.2 Loop Address Utility
In order for the MC to properly communicate with each of the loop control boards, they must be configured for
the proper communications address. The factory default communication settings of the loop control boards are
set for a communications address of one, which correspond to the proper settings for loop 1. For a single loop
MC control system, no further settings are required. Simply connect the communications wiring between the
control board and the MC interface, and the system is ready to go.
For a multi-loop control system, the other loop control board(s) must be set for an address that corresponds
with the loop number, i.e., 2, 3, 4…. If a display module is not available to connect to the loop control board in
order to set its address, the Loop Address Utility can be used. It is accessed from the Setup menu.
In order to use the utility, only one loop control board can be connected to the MC touch screen display at a
time. Since the default address of all control boards is 1, if more than one was connected, they would all
respond to the same command which would cause them all to be set to the entered address. If more than one
loop control board is connected, disconnect the communications wiring from the loop control board(s) that you
DO NOT want to set the address on. An alternative is to remove power from the loop control board rather than
disconnecting the communications wiring.
Configuring the MCT-MC - 21 - FDC MCT-MC
MCT-MC 4.3
With only one loop control board powered on or connected to the MC via the communications link, press the
Loop Number field and enter the address to assign to the attached loop control. Once entered, press the
“Assign Address” button and the utility will begin scanning for the loop control board and set its address to the
one entered once found. If the utility fails to set the address, check the wiring to insure it is properly connected.
If the loop control board has been previously used for another application, it may be possible that the address
or other communications settings have been changed, which prevent the utility from working. In this case, a
display module must be connected to the loop control board to set the proper communications settings:
Address: 1 to 10 (for loop 1 to 10)
Baud rate: 9600
Parity: Even
IMPORTANT: The loop input number corresponds to the communications address that must be set in the
loop control board for the MC to access it properly. If the communications address is not set
properly in the loop control, the MC will not be able to communicate with it, or may communicate
with the wrong loop control and assign incorrect values for the loop.
4.3 Loop Configuration
The Loop Configuration screen is accessed from the Setup menu. The screen provides access to all loop
control board settings. When more than one loop is configured, the left/right scroll buttons will be provided at
the top right of the screen. These buttons are used to scroll through all available loop controls in order to
view/edit settings for each.
The model and version of the loop control attached will be shown in the scroll list header. To view all of the
available settings, simply swipe up or down on the screen to scroll through the list items. To edit a value, tap
the row for the desired item. If the entry is a simple numeric value, the number entry pad will be shown. If the
item has multiple selections to choose from, a list of individual selections for the item will be shown.
IMPORTANT: Care should be taken when configuring loop controls as automatic ramp/soak programs may
be downloaded to any loop configured in the system. Each loop should be configured with the
appropriate settings to insure the ramp/soak programs operate properly. Typically all loops,
with the exception of communication address, are configured identically. This especially
applies to the automatic ramp/soak program global settings.

4.3.1 Tagname
The Tagname entry allows the user or OEM to assign a specific name for each control loop, up to 11 characters
in length. This name will be used throughout the MC runtime application and can be used to provide a more
detailed description as to the function the loop provides. Default tag names are LOOP 1 through LOOP 10.
4.3.2 Input Type
The Input Type entry is used to select the type of sensor that will be connected to the loop control. The input
type can be a temperature input (thermocouple or RTD) or a linear input type (Vdc or mA).
The input type selections are mutually exclusive, i.e., selecting one input will turn all other selections off. Once
the desired input type has been selected, press the “Done” button to set the input type for the loop control board
and return to the main Loop Configuration screen.
NOTE: The loop control board is ordered with either a standard input for thermocouples and RTD’s, a voltage
input or a milliamp input. The selected input type must be set to match the type of input supplied on
the loop control board or the unit will not operate correctly.
4.3.3 Input Units
The Input Units entry is used to select the temperature units for temperature input types (thermocouple or RTD).
If the selected input type for the loop is a linear input (Vdc or mA), the Input Units entry will display the text entry
keypad allowing the user or OEM to enter specific engineering units up to 4 characters.
Configuring the MCT-MC - 23 - FDC MCT-MC
MCT-MC 4.3
The input unit selections for temperature are mutually exclusive, i.e., selecting one will turn off the other. Once
the desired temperature units have been selected, press the “Done” button to set the input units for the loop
control board and return to the main Loop Configuration screen.
4.3.4 Decimal Point
The Decimal Point entry allows the input precision to be adjusted between 0 and 1 decimal digits for temperature
input types, between 0 and 2 for a 0-60mV input and from 0 to 3 for Vdc and mA input types.
IMPORTANT: Once the loop control board has been configured with a specific decimal point, changing the
decimal point will require the loop control board to be reconfigured in order to maintain previous
control settings. Automatic programs, alarm set points, set point limits, input low/high scale,
etc., DO NOT automatically scale. An entry of 100.0 becomes 1000 when changing the
decimal point to zero (not 100), and must be re-entered to set the proper value.
4.3.5 Input Low/High Scale
The Input Low Scale and Input High Scale entries are used to set the input range for linear input types (Vdc or
mA). The entries are not available for temperature input types since they utilize a fixed range based on the
sensor type. The input low scale value can be set from -32768 up to the high scale value minus 50. The high
scale value can be set from the low scale value plus 50 up to 32767.
NOTE: The minimum and maximum scale values are limited by the decimal point selection. For a decimal
of 0, the values are -32768 and 32767 respectively. For one decimal point, the values are -3276.8
and 3276.7. For two decimal digits, the values are -327.68 and 327.67 and for three decimal digits
the values are -32.768 and 37.767.
4.3.6 Input Filter
The Input Filter entry is used to select the time constant used for filtering the process input.
The time constant selections are mutually exclusive, i.e., selecting one will turn off the others. Once the desired
filter constant has been selected, press the “Done” button to set the input filter for the loop control board and
return to the main Loop Configuration screen.
4.3.7 Event Input Function
The Event Input Function is used to select the desired mode of operation for the digital input of the loop control
board. The event input selections are mutually exclusive, i.e., selecting one will turn off the others. Once the
FDC MCT-MC - 24 - Configuring the MCT-MC
MCT-MC 4.3
desired function has been selected, press the “Done” button to set the event input function for the loop control
board and return to the main Loop Configuration screen.
The Automatic program run function is a single-shot action that will start the currently loaded program when
the event input is activated.
The Automatic program hold function will put the currently running program into hold when the event input is
activated. The program will resume operation and return to the run mode when the input is deactivated.
The Automatic program abort function is a single-shot action that will abort the currently running program.
Note that the abort function does not work if the program is in hold. The program must be running in order for
the abort function to work.
The Failure transfer function puts the loop control outputs into failure transfer mode when the input is activated.
The output will then go to the percent output value set for failure transfer. The loop control outputs will return
to normal PID control when the input is deactivated.
NOTE: If an automatic ramp/soak program is in operation and one or both programmed control loops are
placed in failure transfer via the event input, the program will be stopped. When the event input is
then turned off and failure transfer is disabled, the loops will operate in static mode at the set point
and event output status prior to the time which the program was started.
The Automatic program advance next step function is a single-shot action that will advance the currently
running program by one step each time the event input is activated.
The Automatic program run/hold function is a combination of the automatic program run and program hold
functions. Upon first activation of the input, the currently loaded program will be started if not already running.
Deactivating the input will then cause the program to go into hold. The input must then be reactivated in order
for the program to resume operation.
The Loop status input function provides a visual indication on the Loop View screen in the runtime application.
When the input is activated, the border around the loop is highlighted blue. When the input is deactivated, the
border around the loop returns to the default dark gray color. This can be used as a means for alerting the user
of an operating condition, such as the equipment the loop is controlling is in operation.
The Alarm input function allows the event input to be used for alarm indication. When the input is activated,
the Event Input Alarm Message (see section 4.2.8) is displayed on the alarm screen in the runtime application
and the audible alarm sounds.
NOTE: The MC does not support the P41/B42 event input functions of “Manual Mode”, “Off Mode” and “PID2
Select”. These selections are not available through the MC configuration.

4.3.8 Event Input Alarm Message
When the event input function is set to alarm input, the Event Input Alarm Message entry allows the user or
OEM to assign the alarm message that will be shown on the alarm screen in the runtime application when the
input is activated. The alarm message can be up to 25 characters long.
4.3.9 Low/High Limit Setpoint
The low and high limit set points are used to set the minimum and maximum allowed set points that can be
entered for the loop control. These are typically set by the OEM to limit the control range to within the safe
operating range of the equipment.
NOTE: The runtime application provides additional user low and high set point limits. These can be adjusted
to further limit the allowable set point range within the band set by the OEM low and high set point
limits.
4.3.10 Output 1 Function
The Output 1 Function is used to set the mode of operation for the primary control output of the loop control
board. The output can be set for heating or cooling on/off control, time proportioning or linear control. The
output selections are mutually exclusive, i.e., selecting one will turn off the others. Once the desired function
has been selected, press the “Done” button to set the output function for the loop control board and return to
the main Loop Configuration screen.
NOTE: The output function must be set to match the type of output ordered on the loop control board. Relay,
triac and SSR output types are used for on/off and time proportioning control. The isolated Vdc and
mA output types are used for linear control.
The Heating on-off control function will turn on the output when the process value is below set point. When
the process value rises above the set point plus the on-off control hysteresis, the output will turn off.
The Heating time proportioning function uses the PID settings to cycle the output on and off according to the
percentage of heating required using the cycle time configured for output 1. For example, if the percentage of
output is 50% and the cycle time is 18 seconds, the output will repeat on/off cycles of 9 seconds each. If the
output was only 25%, the output would be on for 4.5 seconds and off for 13.5 seconds of the 18 second cycle
time.
The Heating linear control function uses the PID settings to vary the Vdc or mA output from the minimum to
the maximum range of the output as a direct percentage of the heating output.
FDC MCT-MC - 26 - Configuring the MCT-MC
MCT-MC 4.3
The Cooling on-off control function will turn on the output when the process value is above set point. When
the process value falls below the set point minus the on-off control hysteresis, the output will turn off.
The Cooling time proportioning function uses the PID settings to cycle the output on and off according to the
percentage of cooling required using the cycle time configured for output 1. For example, if the percentage of
output is 50% and the cycle time is 6 seconds, the output will repeat on/off cycles of 3 seconds each. If the
output was only 25%, the output would be on for 0.75 seconds and off for 5.25 seconds of the 6 second cycle
time.
The Cooling linear control function uses the PID settings to vary the Vdc or mA output from the minimum to
the maximum range of the output as a direct percentage of the cooling output.
4.3.11 Output 1 Failure Transfer
The output 1 failure transfer setting is used to set the value the output should go to if there is an input failure,
i.e., sensor break. The output can be set for bumpless (-1) operation or a fixed percentage of output (from 0 to
100%) if proportioning or linear control is selected fro the output function. When failure transfer is set to
bumpless, the output will remain at its previous percentage of output until the input condition is corrected. Note
that this should not be used for extended periods of time as a runaway condition could occur if separate limit
devices are not installed to insure safe limits of operation by turning off the system should a limit be exceeded.
If the output function is set for on-off control, the failure transfer can be set to have the output turn on (1) or turn
off (0) when a sensor break occurs.
4.3.12 Output 1 ON-OFF Control Hysteresis
The output 1 on-off control hysteresis can be set when the output 1 function is set for heating or cooling on-off
control. It is used to eliminate rapid cycling of the control output by applying a safe-sided dead band to the
control output. When the control set point is exceeded, the output will turn on. The output will not turn off until
the process rises above (for heating) or falls below (for cooling) the set point by the hysteresis value.
The hysteresis can be set from a minimum of 0.1 to a maximum of 50.0 for units of degrees Centigrade and to
a maximum of 90.0 for units of degrees Fahrenheit and when a linear input type is used.
4.3.13 Output 1 Cycle Time
The output 1 cycle time can be set when the output 1 function is set for heating or cooling proportioning control.
The cycle time can be adjusted from 0.1 to 90.0 seconds. For cycle times less than 18 seconds, it is
recommended that the loop control board be ordered with the triac or SSR drive output for output 1 to extend
the life of the control output.
4.3.14 Output 1 Low/High Limit Values
The output low and high limit values can be set when the output 1 function is set for heating or cooling time
proportioning or linear control. They are used to set the minimum and maximum percentage of output that the
output will control to with a default of 0% for the low and 100% for the high. By raising the low limit or reducing
the high limit, the output will not exceed the output value regardless of the percent output required by the PID
values.
For example, raising the low limit to 5% with the output set for heating proportioning control, even if the process
value is over set point and the PID values are calling for a 0% output, the output will continue to cycle on and
off at 5% heating output.

4.3.15 Output 2 Function
The Output 2 Function is used to set the mode of operation for the secondary control output of the loop control
board.
NOTE: The output function must be set to match the type of output ordered on the loop control board. Relay,
triac and SSR output types are used for proportioning control, alarm or event outputs. The isolated
Vdc and mA output types are used for linear control.
The output can be set for cooling time proportioning or linear control, an alarm or an event. The output
selections are mutually exclusive, i.e., selecting one will turn off the others. Once the desired function has been
selected, press the “Done” button to set the output function for the loop control board and return to the main
Loop Configuration screen.
The Cooling time proportioning function uses the PID settings to cycle the output on and off according to the
percentage of cooling required using the cycle time configured for output 1. For example, if the percentage of
output is 50% and the cycle time is 6 seconds, the output will repeat on/off cycles of 3 seconds each. If the
output was only 25%, the output would be on for 0.75 seconds and off for 5.25 seconds of the 6 second cycle
time.
The Cooling linear control function uses the PID settings to vary the Vdc or mA output from the minimum to
the maximum range of the output as a direct percentage of the cooling output.
The Alarm output function activates the Alarm 1 configuration settings for assigning the type of alarm logic to
apply to output 2. When the alarm condition is active, the output will turn on.
The Reverse alarm output function activates the Alarm 1 configuration settings for assigning the type of alarm
logic to apply to output 2. The output will be normally “on” when this function is selected. When the alarm
condition is active, the output will turn off.
The Event output function allows the output to be turned on and off via an automatic program or manually
through the MC runtime application to act as a “soft” switch to turn system components on and off.
The DC power supply output function must be selected when the output type ordered for the loop control
board output 2 is a transmitter power supply.

4.3.16 Output 2 Failure Transfer
The output 2 failure transfer setting is used to set the value the output should go to if there is an input failure,
i.e., sensor break. The output can be set for bumpless (-1) operation or a fixed percentage of output (from 0 to
100%) if proportioning or linear control is selected for the output function. When failure transfer is set to
bumpless, the output will remain at its previous percentage of output until the input condition is corrected. Note
that this should not be used for extended periods of time as a runaway condition could occur if separate limit
devices are not installed to insure safe limits of operation by turning off the system should a limit be exceeded.
If the output function is set as an alarm, the failure transfer can be set to have the output turn on (1) or turn off
(0) when a sensor break occurs.
4.3.17 Output 2 Low/High Limit Values
The output low and high limit values can be set when the output 2 function is set for cooling time proportioning
or linear control. They are used to set the minimum and maximum percentage of output that the output will
control to with a default of 0% for the low and 100% for the high. By raising the low limit or reducing the high
limit, the output will not exceed the output value regardless of the percent output required by the PID values.
For example, by reducing the high limit to 80%, even if the process value is over set point and the PID values
are calling for 100% cooling, the output will only produce an 80% cooling output.
4.3.18 Output 3 Function
The Output 3 Function selection is used to configure the loop control board output as an alarm or an event.
The output selections are mutually exclusive, i.e., selecting one will turn off the others. Once the desired
function has been selected, press the “Done” button to set the output function and return to the main Loop
Configuration screen.
The Alarm output function activates the Alarm 2 configuration settings for assigning the type of alarm logic to
apply to output 3. When the alarm condition is active, the output will turn on.
The Reverse alarm output function activates the Alarm 2 configuration settings for assigning the type of alarm
logic to apply to output 3. The output will be normally “on” when this function is selected. When the alarm
condition is active, the output will turn off.
The Event output function allows the output to be turned on and off via an automatic program or manually
through the MC runtime application to act as a “soft” switch to turn system components on and off.
The DC power supply output function must be selected when the output type ordered for the loop control
board output 3 is a transmitter power supply.

4.3.19 Output 3 Failure Transfer
The output 3 failure transfer setting is used to set whether the output should be on (1) or off (0) when there is
an input failure, i.e., sensor break. The setting applies to alarm output functions only.
4.3.20 Output 4 Function
The Output 4 Function selection is used to configure the loop control board output as an alarm, event or
retransmit output. The output selections are mutually exclusive, i.e., selecting one will turn off the others. Once
the desired function has been selected, press the “Done” button to set the output function and return to the
main Loop Configuration screen.
NOTE: The output function must be set to match the type of output ordered on the loop control board. Relay,
triac and SSR output types are used for alarm or event outputs. The retransmission Vdc and mA
output types are used for process value or set point retransmit.
The Alarm output function activates the Alarm 3 configuration settings for assigning the type of alarm logic to
apply to output 4. When the alarm condition is active, the output will turn on.
The Reverse alarm output function activates the Alarm 3 configuration settings for assigning the type of alarm
logic to apply to output 4. The output will be normally “on” when this function is selected. When the alarm
condition is active, the output will turn off.
The Event output function allows the output to be turned on and off via an automatic program or manually
through the MC runtime application to act as a “soft” switch to turn system components on and off.
The Retransmit process value and Retransmit setpoint value functions allow the loop control board output
to retransmit the current input value or control set point to remote devices such as a chart recorder.
The DC power supply output function must be selected when the output type ordered for the loop control
board output 4 is a transmitter power supply.
4.3.21 Output 4 Failure Transfer
The output 4 failure transfer setting is used to set whether the output should be on (1) or off (0) when there is
an input failure, i.e., sensor break. The setting applies to alarm output functions only.
