VFE2500

    DOUBLE FEEDBACK SYSTEM:

  • Distance and velocity closed-loop system
  • After the door width is learned, the VFE2500 will optimize control of the elevator door(s)

    SAFETY STANDARDS:

  • CSA Certified. B44.1/ASME - A17.5
  • Complies withthe following CE and IEEE safety standards:
  • EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-5, EN61000-4-6, EN61000-4-8, and IEEE STD C2.45-1992 EMC Conformity Report is available

    A POWERFUL SYSTEM:

  • 230VAC and 115VAC power supply versions available
  • A 1/2 HP AC motor is used to accommodate most door loads, friction, and wind pressure

    HARMONIC AND LINEAR MODELS ARE AVAILABLE:

  • Three models of VFE2500 are currentlty available:
  • VFE2500-HH: Heavy duty Harmonic model
  • VFE2500-GL: Light duty Linear model
  • VFE2500-HL: Heavy duty Linear model

    NON-CONTACT SENSORS:

  • Non-contact optical and hall effect sensors are used

    CONVENIENCE INDICATORS

  • Light Emiting Diodes (LEDs) on the main board are used to indicate status of all important functions

    UNIVERSAL INPUTS AND OUTPUTS:

  • Universal inputs accept control signals in form of contacts or signal voltages: from 24 - 230V, AC or DC
  • Output contacts rated at 10A, 230VAC
  • All input modules, output relays, and conectors are pluggable for easy replacement

    TOGGLE SWITCHES FOR MANUAL TESTING:

  • Toggle switches are provided for manual operation, diagnostics, and operational verification, regardless of the condition of control wiring to the elevator controller

    OVER-TORQUE AND OVER SPEED DETECTIONS:

  • Over-torque and over-speed detection and restriction are parameterized for easy adjustment to comply with codes

    PLUG-AND-PLAY INFRARED DETECTOR EDGES:

  • Both NPN and PNP edges can be connected directly to the VFE2500, simplifying electrical wiring and eliminating the need for an extra power supply

    SPECIAL FEATURES ADDED:

  • Combined VVVF drive and main board together makes the VFE2500 drive easily interchangeable from one model or job to another

    Additional I/O for special application of:

  • Heavier door, Narrower door, Detector edges timeout for Nudging application, Buzzer output for alarm before Nudging speed is applied

    RELIABLE AND HIGHT RESOLUTION FEEDBACK:

  • High resolution encoader and galvanic isolation techniques are used to deliver smooth operation
  • Hardware and software encoder loss detection are employed to prevent the run-away nature of a closed-loop control system.This combination of hardware and software provides an ultimate protection for human life

    SERIAL COMMUNICATION TO VFE2500:

  • CAN (Controlled Area Network) and other communication protocols can be used for serial communication with the VFE2500

    AUTO FALL BACK TO SLOW MODE IF SENSORS OR ENCODER FAIL:

  • If both DOL and DCL sensors fail, or if the encoder fails, the VFE2500 door operator will continue to operate in slow scanning mode until repairs are completed
