DIGITAL INTELLIBOARD

Designed to continuously and homogeneously regulate the speed of EC motors using MODBUS RS485 serial communication protocol, as well as control and run diagnostics on on-board systems (adiabatic systems, pressure, temperature and humidity sensors, UV lamps). With the technology used on Electronic Commutation (EC) fans, operation is versatile and optimal with the consequent energy savings and noise reduction. Any faults/anomalies are univocally identified in a detailed way. The control panel is supplied installed, wired, programmed and ready-to-use.
Features:
  1. Power supply: 3-phase 380-480V/50-60Hz.
  2. Certifications: UL, CSA, EC.
  3. UV resistant; protection class IP55.
  4. CAREL 4,3” touchscreen color display.
  5. Protective Screen.
  6. Lockable door.
  7. Main switch.
  8. Key operated switch for maintenance.
  9. Fans alarm red light.
  10. CAREL Programmable Logic Controller (PLC).
  11. “FLEXI” multi-pin plug/socket connectors.
  12. Fans protection with circuit breakers.
Connectivity
Full remote control (over 900 parameters available) through field BUS (standard: MODBUS RS485; on request: LonWorks®, BACnetTM, SNMP, Konnex®).
Functions:
  • Proportional-Integral-Derivative heat regulation.
  • For remote control (reference: speed or temperature/pressure setpoint) with 0-10V signalor field BUS.
  • Limits fan rotation speed (ex. to limit noise levels during the night).
  • Enables anticlockwise fan running to clean finned heat exchangers.
  • Sends an analog 0-10V signal proportional to fan speed (0-100%).
  • Update software with USB stick, without using a PC.
  • Optional: for regulating 2 independent fan banks separately and independently (ex. different rotation speeds).
  • Optional: Ethernet connection (ex. control parameters on a web page, remote assistance from the works, software update, etc.).
  • Optional:sends an e-mail to max.10 users for each alarm event (if the e-mail addresses have been registered in the PLC memory and the system is connected to Ethernet).
