If any problem is noticed upon reception, immediately contact the transport com- pany and/or CIRCUTOR’s after-sales service. 1�1�- STORAGE The device should be stored according to the following recommendations: •Avoid placing it on uneven surfaces.
  • Page 8 The MDC-20 has an internal web server from which the user can view in real time the variables mea- sured and others obtained by calculation, and the status of the device inputs and outputs with the possibility of managing them.
  • Page 9 The device 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 devices connected to the field bus, although it is not read immediately.

  • Page 18 The device can synchronise the date and time through an NTP (Network Time Protocol) server in the UTC time system. By default, the MDC-20 does not display any value, indicating that synchronisation is completed via DHCP, provided the network server allows this.
  • Page 19 MDC-20 After selecting the zone, press the button, moving to the next screen. After validating this option, you will move to the Active Mode menu, “5.5.- ACTIVE MODE AMB®”. 5�5�- ACTIVE MODE AMB® The AMB (Active Mode Bridge) system reverses the server client role in the process of connecting re- mote devices.
  • Page 20 By default the HTTP (Hypertext Transfer Protocol) uses port 80 to communicate with an application. The MDC-20, like all web servers, uses this port by default but allows you to change it to configure other options. For example, secure access to certain web sites is with the HTTPS protocol, which nor- mally uses port 443 instead of 80.
  • Page 21 If there is no authentication configuration by the DHCP system, and if there is no Primary and Secon- dary NTP server available, MDC-20 allows the time and date to be configured manually when valida- ting the changes by displaying the caption “Adjust clock”. The date and time are displayed on screen with the following format: YYYY-MM-DD HH:MM.

  • Page 34 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 35 This sync pulse output must lead to one of the device inputs to be synchronised, in this case, the MDC-20. The input used for synchronisation must be configured in the corresponding field after selec- ting 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.

Normally an input in a local or remote device is used, wiring the status of the relay that controls the load.
  • Page 47 MDC-20 Figure 52:Type of calendar� DAILY This menu lets you select the time intervals when you want loads to be disconnected without being able to be controlled by the system. The user must indicate in red the time intervals when they want the loads to be disconnected. In the green time intervals, the loads are available for management by the power control system.
  • Page 48 MDC-20 ANNUAL The annual time control allows you to configure the disconnection of loads every day of the year ac- cording to the daily types of time control configured previously. Figure 55:Configuration of year periods� The configured calendars are associated with each load, selecting them from the drop-down menu in the main load setup window.
  • Page 49 MDC-20 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 Figure 57: 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.
  • Page 50 MDC-20 8�2�2�- SIMULATION LOG The simulation menu log tab shows a graphic with the simulated data log. Figure 58: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.
