1 VERIFICATION UPON RECEPTION
Check the following points when you receive the unit:
• The unit meets the specifications on your order.
• The unit has not suffered any damage during transport.
• Perform an external visual inspection of the unit prior to switching it on
• Check that the power supply voltage of the unit is right for the mains to which it is to be
connected
If any problem is detected
company and/or CIRCUTOR's after-sales service
Read this manual carefully before connecting the unit in order to avoid incorrect use that may
cause permanent damage.
This manual contains all the necessary information for the safe use of the units and getting the
best performance out of them.
1.1 Storage
The unit should be stored according to the following recommendations:
• Avoid placing it on uneven surfaces.
• Do not store in outdoor areas, humid areas or areas exposed to the splashing of water.
• Do not install near hot spots (maximum ambient temperature: 45 ºC)
• Avoid saline and corrosive environments.
• Avoid storing the unit in areas where dust is generated or where the risk of chemical or
other types of contamination is present.
• Do not place any weight on top of the unit.
2 PRODUCT DESCRIPTION
The MDC-20 is a maximum demand controller, which controls the power demanded by an
installation (or part of it) based on disconnecting certain dispensable loads before the power
exceeds certain limits. This prevents the consumption of excess power or peaks, which
generally result in high penalties in the electricity bill or unwanted tripping of the current limiters.
It is recommended that non-priority loads are disconnected, so that demand management does
not affect the normal working of the installation.
The MD C-20 has an internal web server from which the user can view in real time the variables
measured and others obtained by calculation, and the status of the unit inputs and outputs with
the possibility of managing them.
In addition to providing data reading/writing via the web, the unit has an XML server, enabling
the user to send GET and PUT type requests.
User Manual Page 9 of 58
MDC-20
2.1 Internal WEB SERVER
The MDC-20 has an internal WEB server that allows you to connect to an Ethernet network.
This allows the user to read internal variables in real time or obtain historic logs as graphics or
tables.
To connect to the Ethernet network, the MDC-20 must be correctly configured. Once configured
and integrated in the Ethernet network, the unit variables are visible to the user via a
conventional Internet browser, provided the appropriate Java virtual machine is available and
installed on the computer. The machine is available at the following address:
http://www.java.com/es/download. Another way of viewing the variables on the unit is through
the PowerStudio® Scada Client which must be installed on the computer.
To communicate with the unit via the web and view the variables on the browser, the user must
access an IP address or an alias in DHCP (Dynamic Host Configuration Protocol) page nam e
format:
http://xxx.xxx.xxx.xxx ,
or the DHCP name, http://name_dhcp ; where:
xxx.xxx.xxx.xxx is the IP address assigned by the user and
name_dhcp is the name assigned and authenticated by the local area network (LAN) name
server.
2.2 XML server
XML, which stands for eXtensible Markup Language, is a mark-up language developed by the
World Wide Web Consortium (W3C) used to store machine-readable data.
XML is a standard for exchanging structured information between different platforms
(databases, tables of variables, text editors, spreadsheets, etc.)
The XML server is an excellent tool for integrating MDC-20 with external applications.
2.3 Digital inputs
The MDC -20 has 8 digital inputs, whose function is to count impulses from external analyzers or
to detect the logic state of external sensors (voltage free contacts). The contacts for activating
the unit's digital inputs must be voltage-free contacts (the device provides an internal power
supply). The unit detects an open or closed contact between a common terminal and the
corresponding input terminal.
2.3.1 Impulse counter function
It is normal for fluid or energy meters to be equipped with an impulse output with a frequency
proportional to the measured energy or flow. The MDC-20 can be used as a centralising
metering unit, using its 8 digital inputs for reading as many meters as available inputs. Not e that
this enables centralising electrical energy metering, as well as water, gas, hot water meters, etc.
which have a pulse output channel.
The unit is equipped with 8 non-volatile memory logs that add together the logs of the abovementioned energy meters. Each log is 32 bits (4 bytes), so it counts a maximum of up to
4,294,967,295 impulses. When a log reaches said maximum value, the next impulse resets the
energy meter to zero.

MDC-20
Without the PowerStudio® or PowerStudio®Scada Editor, it is not possible to
2.4 Digital outputs
The unit has 6 relay digital outputs. Through the communication servers, the user can remotely
manage the outputs (i.e. you can open, close, generate an impulse, etc.).
These actions can be carried out manually or by a program, determined by events detected by
the unit (see PowerStudio® Scada software manual).
2.5 RS-485 communication bus
The unit has a RS-485 communication bus for linking to external peripherals through a field bus.
The MDC-20 can act as a field bus master and temporarily store data on the peripherals in a
200MB internal memory, which is filled cyclically, deleting the oldest data. That memory and the
web access capacity enables real time viewing for the user and being able to record the data
from the units connected to the f ield bus, although it is not read immediately. The PowerStudio®
Scada software allows the simple production of calculations using the measured variables and
the display in graphics and tables of the various parameters recorded.
2.6 PowerStudio® and PowerStudio® SCADA Software
To config u re t he f ie ld bus and manage both real time and historical data, the user must connect
the MDC-20 to a computer (normally via the Ethernet) and install in that computer one of the
PowerStudio® or PowerStudio® Scada applications. This makes it possible to export the
configuration of the unit and add or remove analyzers or slaves connected to the field bus. T he
MDC-20 allows you to configure up to a maximum of 5 slave units connected to your network.
For more details on how to configure all the system features, read the PowerStudio®/Scada
Editor manual, where you can find all the information on:
• Importing or exporting the configuration of the MDC-20 system
• Configuring new units or slaves
• Tariff discriminators / calendars
• Calculated variables.
• System events and alarms.
• Authentication configuration.
• Web system security.
• Etc.
configure the power control application, and equip the MDC-20 with all its features.

The “Act.ModePort” option allows you to configure the access port to the central server
peripherals, in which the AMB (Active Mode Bridge) connection software will have been
installed. This computer must have an access port for connecting all remote units, in order to
establish a transparent communications tunnel.
The central server is connected to the Internet through a router, in which a NAT (Network
Address Translation) access rule is established which assigns f loating IP, in order to establish
the connection path to the various peripherals.
An access port must be activated in the Internet access router which will internally transfer the
public communication frames to the AMB internal connection server and to a port specified by
and known to the user.
The port enabled in the communication router must be configured in the "Port" section.

Meters: It is possible to configure the following parameters for each of the eight meters:
• Description: Alphanumeric name to identify the meter on the unit screen.
• Unit: Alphanumeric type data to identify the meter units.
• Factor: Multiplier value of each pulse, (for example kWh/impulse ratio)
Flows: Checking the selector will activate the flow variable. If this selector is not activated, it
will not be possible to view the flow value of the corresponding controller input.
Fig.7-8 . – Configuration of flow meters
To configure the flow meters the following fields must be defined:
• Description: Alphanumeric type data which allows you to enter a brief description of the
flow for better identification.
• Unit: Alphanumeric type data which permits a brief description of the units where the
flow is shown to be entered.
• Factor: Multiplier value of each input impulse, (for example litres/impulse)

7.5.5 Variable limits
This menu option (see Fig.7-4) lets you configure the nominal values of the variables, as well as
a series of margins to display on screen when a variable measures values outside the
configured range, in order to easily detect anomalous values.
In the MDC-20 the limits of the variables only refer to flow values as there is no point
referencing them to either impulse or status values. For this reason the fields appear disabled if
the inputs have not been configured as flow meters.
Fig.7-12 . – Limit values setup
• Nominal Value: Indicate the nominal flow value for each channel. If the nominal value is
0, the alarm is disabled.
• Pre-alarm or lower alarm: In the channel 1 example, when the value of the variable is
between 5% and 10% below the nominal value, there will be a pre-alarm s ignal; if it is
below 10% the alarm will sound.
• Pre-alarm or upper alarm: In this case when the variable value is between 5% and
20% above the nominal value, there will be a pre-alarm signal; if it is above 20% the
alarm will sound. If the pre-alarm value is equal to the alarm value, the pre-alarm zone
will be disabled, passing directly from normal to alarm status.

unit, using the and buttons.
8 POWER CONTROL CONFIGURATION
The MDC-20 is especially designed for Power Control. With a correct configuration you can
connect and disconnect loads to and from your installation according to the total current
demand value and instantaneous consumption, to ensure that the maximum power contracted
is not exceeded. You can therefore avoid penalties for power peak consumption.
The parameters to be configured for adapting the MDC-20 to your installation are programmed
in the following submenus: Parameters, Groups and Loads.
Page 30 of 58 User Manual
MDC-20
8.1 Power control parameters
The power control configuration parameters are shown in the following menu (Fig.8-1),
explained in detail below.
Fig.8-1 . – Power control parameters to be configured
8.1.1 General
Fig.8-2 . – General parameters configuration screen
• Integration period (minutes): Configure the time in minutes of the energy values
integration window. After this time, the calculation will return to zero.
• Instantaneous value: You need to enter an incremental energy variable or incremental
energy impulse meter. You can use the help button to enter a unit's energy variable, an
impulse meter or a formula whose result is an incremental energy value .
• External synchronisation: In general, all billing meters have a sync output. This output
is used so that other units that measure the installation's electrical parameters do so in
User Manual Page 31 of 58
MDC-20
sync with the main meter. This sync pulse output must lead to one of the unit inputs to
be synchronised, in this case, the MDC-20. The input used for synchronisation must be
configured in the corresponding field after selecting the external synchronisation
checkbox. It is understood that there is a sync pulse when there is a change in the logic
state from 0 to 1 in the variable or configured input. If the external synchronisation box is
not selected, the internal clock of the MDC-20 will be used for synchronisation.
8.1.2 Alarms
The unit has two very useful alarms for managing the installation that can be used so that the
system warns the user of any anomaly.
Fig.8-3 . – Alarm setup screen.
• Control alarm: Variable or physical output to be activated as an alarm in case of
exceeding the maximum power configured in the MDC-20 and the unit has no more
loads to disconnect.
• Communications alarm: Variable physical output to be activated as an alarm if one of
the installation units does not communicate with the controller or is in any of the error
states.
8.1.3 Safety margin over the setpoint (%):
• Safety margin in % over the maximum set point at the end of a period. For example, if
you configure 10% in the set point margin and the maximum energy is 150 kWh, your
real set point will be: 150-10%=135 kWh
Fig.8-4 . – Configuration of safety margin
8.1.4 Simulation
The information entered in these fields is only used in the simulation window (see section0). The
simulation shows how the system will respond when it starts working. The more accurate the
information entered, the more real the simulation by the program.
Fig.8-5 . – Simulation configuration screen
• Uncontrolled load (kW):Enter in this field the total power of the installation not subject
to power control (loads not controlled by the MDC-20), which generally coincide with
priority loads that cannot be disconnected.
• Variation factor (%): Variation of total power of installation in %, so that the simulation
does not always work with the maximum theoretical values configured and is more real.

configured in this section takes priority over that configured in the maximum
demand control by calendar.
8.1.5 Maximum power by conditions.
With this menu option you can configure a maximum power for the installation according to the
status of any input on the unit or any external condition that can be measured or detected with
the MDC-20.
Fig.8-6 . – Configuration of conditions
The list of conditions configured by the user will be applied by the controller to manage the
maximum power permitted in the installation. The conditions entered on the screen can be any
valid expression in the Power Studio language, with variables of any unit integrated in the
network or input of the MDC-20 itself.
The set point is the maximum power value permitted in the installation when the condition is
active.
The controller will follow the order of assessment of conditions established in the list and the
first condition met will be applied.

8.1.7 Window type:
Allows you to select the type of integration window used to apply the power control.
Fig.8-9 . – Integration window
• Fixed window: The integration window time is of equal duration to that configured in the
“integration period” field (chapter 8.1.1). If there is an external sync pulse, the window
time will be equal to the time between impulses. If a sync pulse occurs or the integration
period configured by the user has finished, that integration period will be restarted by
resetting the energy meter for the period back to zero.
Fig.8-10 . – Fixed integration window
• Sliding blocks: The integration period is divided into N time intervals equal to that
configured in the “integration time” field. The calculation window therefore consists of N
sliding blocks.
Fig.8-11 . – Sliding blocks integration window
Page 34 of 58 User Manual
MDC-20
The Integration Period must be a multiple of the Integration Time (chapter
8.1.1).
The following fields must be configured when selecting the sliding blocks window:
Fig.8-12 . – Parameters to be configured in the sliding window
• Integration time (seconds):Duration time of each of the N partial integration intervals
included in an Integration Period.
• Excess (%): Excess energy allowed in the integration subinterval always ensuring that
the total energy for the period is less than the configured maximum.
8.1.8 Response time (seconds)
Fig.8-13 . – Response times
• Time between actions: This is the time established between actions. A value of 60
seconds means that once a load has been connected or disconnected, the controller will
wait 60 seconds before carrying out any other operation.
• Non-reclosing time at end of period: Time before the end of an integration period,
during which no new loads are connected until a new integration period has begun.
8.1.9 Maximum power per calendar:
Within the maximum power calendar option you can configure a maximum set point power
according to a time discriminator or calendar, in cases in which the maximum power changes
are based on time intervals or other conditions.
Fig.8-14 . – Selection of calendar
User Manual Page 35 of 58
MDC-20
To create a new discriminators calendar press “Add”. (seeFig.8-15). If you right-click t he mouse

and to define the different maximum powers for each time interval or discriminator.
Fig.8-16 . – Selection of type of discriminator
In a formula with another variable, the value of the variable outside the slot defined by the user
for the discriminator is considered invalid if the option is not marked. This option considers value
0 for the variables, outside the discriminators interval. This option is usually selected if you want
to process one or several discriminated variables.

8.1.10 Load groups:
You can create load groups in the menu option. The groups acquire a different property
depending on their place in the list, with the first group in the list having the highest priority and
the last group the lowest. This allows the user to group together loads within groups depending
on their connection and disconnection priority.
User Manual Page 39 of 58
MDC-20
Each group shows the load disconnection sequence that has been configured and the total
powers of the loads for the group. The load list in the group, the power configured for each load
and the associated disconnection calendar, if applicable, are shown on the right-hand side.
When accessing the load group tab (Fig.8-25) you can add new groups or modify or remove
existing groups. You can also add or remove loads to and from a group.
With the buttons / you can modify the position of the groups and loads in the table, thus
changing the order of priority.
Fig.8-25 . – Configuration of load groups
To add a new load group you must select the button “Add” from the left-hand side of the
menu. When adding a new load group, the user must indicate the name and sequence of the
load group.
Fig.8-26 . – Add groups
Name: Define the required name for that load group.
Sequence: Define the order in which the loads will be connected/disconnected in the group.
• LIFO: The last load that is disconnected will be the first to be connected.
• FIFO: The load that has been disconnected the longest will be the first to be connected,
cyclic queue.

MDC-20
The load order affects the first time that actions are carried out with the loads; the rest of the
parameters configured are then assessed for connection or disconnection.
8.1.11 Loads wit hin a group
This option shows a table with all the loads configured in the control system. The table shows
very important information on each of the loads such as the group to which they belong, the
input or variable associated with controlling the load status, the output or variable associated
with carrying out load actions, the disconnection calendar assigned to it (if applicable) and the
configured power.

8.1.11.1 General Name: Load name. Maximum value: Theoretical maximum power value of load. This value is considered when
connecting the load.
Instantaneous value: Instantaneous power value of the load. This power must be read by a
power analyzer or unit that calculates this variable. If there is no measurement unit, the value to
be entered must be the same as the maximum theoretical value. This value is taken into
account when disconnecting the load.
Enabled: Allows you to enable/disable the load. If the value is 1 (or positive) it means that the
load is available for power control. If the value is 0 (or negative) it means that the load is not
available for power control (disabled) and is disconnected. This can be used as manual load
disconnection.
If the load is disabled, a grey icon will be displayed in the client and no actions will be
permitted with the load in the load action window.
Variation factor %: Percentage value that causes the power of the load to vary so that the
consumption in the simulation is not constant (0% – 20%).
8.1.11.2 Load group
Group to which the load belongs. A load must necessarily belong to a single group.
If the user has not created a group previously to which to associate the load or if the load should
be assigned to a new group, you can access the group creation menu directly with the Add
group button.
8.1.11.3 Time (seconds) Maximum disconnection time: Maximum time that the load can be disconnected. Minimum disconnection time: Minimum time that the load must be disconnected. Minimum connected time: Minimum time that the load must be connected.
8.1.11.4 Control
The inputs used to control the status of the loads and outputs used for actions on them must be
configured in the following fields.
Status control: Variable used to read the status of the load. Normally an input in a local or
remote unit is used, wiring the status of the relay that controls the load. If the status of the relay
that controls the load has not been wired, the same output can be configured, although this
does not guarantee having accurate information on the load status.
Action control: Variable used to modify the status of the load. Normally a unit output is used,
either local or remote, which acts directly on the load or on an actuator that regulates the load.
8.1.11.5 Load deactivation calendar
This section allows you to configure time intervals when you want the loads to remain
disconnected and, therefore, outside the power control system.

8.2 POWER CONTROL SIMULATION
The application has a tool that allows the user to check the correct working of their
configuration.
8.2.1 Simulation
Fig.8-36 . – Graphic obtained by simulation
The graphic part shows all the configured loads. The load status is indicated by a light indicator.
If the indicator is red it indicates that the load is disconnected. If the indicator is green it
indicates that the load is connected.
• Date and Time: The date and time of the simulation will appear in real time. You can
modify and enter another date and time.
• Speed (iter/sec): Number of iterations per second. A value of 60 means that for every
real second the program will advance 60 simulated seconds.
• Maximum value: W hen pressing the right-hand button, the set point value will be that
on the general calendar. If it is not pressed, a set point value can be entered manually.
• Calendar: Indicates whether hourly discrimination per calendar needs to be used in the
simulation and selects the calendar that has been configured in section 8.1.9.
• Average power: It is the average power value of the installation.
• Start: Starts or stops the simulation of the installation.
In the list where the loads configured in the system are displayed, if you right-click the mouse a
menu will appear where you can select the forced connection, forced disconnection or release
of each of the loads.
The light indications of the loads vary according to their status.
Load connected. Automatic management determined by programming.
Load disconnected. Automatic management determined by programming.
Forced load connection. This load cannot be disconnected until it is released.
For ced load disconnection. This load cannot be connected until it is released.
8.2.2 Simulation log
The simulation menu log tab shows a graphic with the simulated data log.
Page 46 of 58 User Manual
MDC-20
Fig.8-37 . – Simulated data log
When carrying out the simulation, the program creates a file where it saves the values being
simulated. This file saves the data each month. The graphics and events represented are data
which has been stored in that file.
The file start date and end date are displayed. The graphic shows the simulation consumption
(KWh), set point and average power of the simulation (KW med). Time is shown as a whole day
in the graphic.
To view a different interval to that shown, open the date menu and select the required date.

8.2.3 Simulated events
The events option allows you to separately view the connection/disconnection of each of the
simulated installation loads. When pressing events the following screen is displayed.
User Manual Page 47 of 58

Fig.8-39 . – Display of events (simulated)
In the graphic, time is divided into two hour intervals. If you left-click the mouse on the graphic,
a cursor will appear where with the arrow buttons you can move along each point of the graphic
and view the time at that point.
There are various tabs in the Events screen that enable different options for representing
events. The options are as follows:

8.3.1 MDC-20 unit
If the MDC-20 display is selected, in the General window you can see the values of the meters
and the status of the inputs and outputs of the units previously configured in the menu of section
7.5.3.
Fig.8-43 . – Display of MDC-20
Communications can be used to manage the digital outputs of the unit making it possible to
open, close or generate an impulse remotely. These commands have priority over the power
control so if an output is opened or closed, the associated load will be connected or
disconnected until a new action is determined for it by the algorithm.
8.3.2 Power control
The power control option displays the window of the real evolution of the system. The REAL,
SETPOINT and TREND variables are shown in real time in the window.
• Real: This is the total consumption for the period in progress calculated according to the
configured energy variable.
• Set point: Consumption value that cannot be exceeded and depends on the maximum
power configured.
• Trend: Estimated consumption value at the end of the period based on current (real)
consumption.

8.3.3 Load action
The load action option displays the loads configured in the system associated with several
buttons that allow you to force the connection or disconnection of the load or release the load
from any lock for its management by the system. If the load is not enabled, all the deactivated
fields appear so it is not possible to take any action on the load.
Fig.8-45 . – Screen for forcing loads
• Connect: This option connects the load permanently, with it no longer being available
for the power control system until its disconnection is released or forced manually.
• Disconnect: This option disconnects the load permanently, with it no longer being
available for the power control system until its connection is released or forced manually.
• Free: This cancels the forced connection or disconnection so that the load becomes
available again for the power control system.
When there is a change in status of the loads in this option, the load icon in the power control
option changes.
Fig.8-46 . – Forced load icons
User Manual Page 51 of 58

Manually connected load. This load cannot be disconnected until it is released
Manually disconnected load. This load cannot be connected until it is released.
Load not enabled for management by the system. See enable in chapter 0.
Load without information on status. The remote unit does not communicate and it is not
possible to know the status of the loads. These can be connected or disconnected.
8.3.4 Graphic display
This unit allows the following graphic options: the display of the value of the impulse meters (if
the inputs have been configured as meters) or the status of the inputs, the graphic display of the
variables belonging to the power controller or
information on the status of the system loads.

The information displayed on the screen of these discriminators is very important as it allows
the user to know the time accumulated in each time interval, the time remaining until
deactivation and how much time is left until that time period is reactivated.
The active interval is also permanently identified with an icon that changes to green when the
period is active and grey when it is deactivated.
