KEYPAD (PARAMETER UNIT):
   • Keypad programmer with LCD display is included to
     adjust, monitor, copy, and upload parameters & parameter
     sets, and to learn the door width distance

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

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
