Function Mode

    • Master – automatic controller:
      the control can be programmed to operate in two different modes:
      • PID with "IES" technology to maintain the controlled variable (eg temperature, pressure) at the set value (set-point)
      • P (Proportional) to maintain the controlled variable (eg temperature, pressure) within the proportional band.
    • Slave Unit:
      the fans regulation changes directly/inversely to the incoming signal/s.
The regulation can be Direct (DIR) or Reverse (REV).

The alarm System is visible on the display, and is supported remotely, with different programmable modes, by the switching of 2 dedicated relays: one for alarms and one for signaling anomalies that do not stop the plant.
There are many additional features including:
  • the automatic configuration of the system, depending on the selected mode: Modbus or 0-10Vdc
  • the Automatic configuration based on the available protocols: ebm-papst and Ziehl-Abegg
  • fans sequential address (ID), automatic or manual, single or bradcast
  • The programming of the connected fans, in the presence of functional changes or in case of fan replacement
  • the programming of speed limits for: Night regulation, Adiabatic System, Cleaning heat exchanger, Cut-Off and Over-Speed, Max & Min RPM%
  • The homogeneous adjustment of the speed of all the connected fans
  • activation of the "Low-Capacity" for the Winter management of the fans
  • function Maintenance System The function
  • AIR-Emergency in case of failure of the control system, which regulates the fan speed to a predetermined emergency
  • The "Black-box" monitoring and the automatic acquisition of events and all significant parameters of Warning or alarm system and connected fans
  • The "Watch-dog" for possible Warning on the fans running
  • The possibility of integrating the control of fans with the adiabatic system with a single user interface and a network connection with the Modbus SCADA software (SCADA)

What's

EC Manager device is a multifunction digital unit, with 3 transducer inputs, specialized for the managment of EC fans Motors. Designed using a "state of art" microcontroller, is suited to have a choice of 13 different default configurations. EC Manager is the only controller with integrated ebm-past and Ziehl-Abegg protocols, ready to drive EC fans trough Master Modbus network and Master 0-10Vdc net connections. It’s optimized with software “IES”, the innovative control algorithm for HVAC&R applications. The Management of WET&DRY System (adiabatic booster) is included in the firmware, driving an optional Spray system with its own Set-Point and proportional band. Using a serial Modbus (RTU) line, it’s possible to read & write all the control parameters of the devices and all the fans, testing and adjusting also the state of the machine from a remote sites. A Selpro software called Clima-Sinergy is already allowable. Clima-Sinergy allows data collection, analysis with graphs, change of working parameters, optimization of performances, for remote control & service.
