KM-20 Control Board

Door Control Board for 24 VDC Motor Telescopic Lift Doors

KM-20 Control Board

• Based on slow speed signal input, a nudging function is used, which allows for closing the door slowly with an audible
  alarm in case of failure of photocell for a long time, without considering the photocell signal.
• Suitable for use with fire lift doors (high speed signal input can be detected).
• Optional KM-20 keypad allows for adjustment of all system parameters. The operation of the door can be extensively followed up.
• Basic parameters (door opening-closing speed, obstruction pressure, signal type and demo mode) can be easily adjusted via 7-segment displays and buttons on the board.

Features

• Door Control Boards are produced for telescopic lift doors with 24VDC reducer and DC motor.
• It provides complete management of the motor with its 4-zone motor control and double channel, high resolution encoder input.
• Thanks to its advanced software, it enables for serial but vibration-less door movements through real S softening on observation ramps and its algorithm that does not require limits.
• Limit switch is not required for door operator. Door width and door opened, and closed positions are automatically identified.
• For operation fully integrated with the control panels, the door might transmit contract outputs such as ‘fully open, fully closed and obstruction/photocell detected’.
• In case of power failure, it can operate with 2 pieces of 12V batteries or 24VDC external supply. The emergency supply type can be easily selected via the jumper on board.
• Battery is charged by the board. It goes into sleep mode and protects the batteries from discharging upon opening the door due to emergency.
• For manufacturers, parameters that ensure flexibility in application such as motor reduction ratio, motor cycle, drive pulley circumference and Skate Opening zone could be provided.
• For user settings, speed settings designated in centimeters/seconds and ramp ways designated in centimeters could be assigned.
• It is possible to follow up the operation of the door, by using the on/off counter.
• Turkish, English and Greek language options are available.
• In case of door obstruction, the door could be re-opened with buzzer warning. Possible damage on passengers and door is prevented by moving from the obstruction zone slowly.
• Door open and close holding pressure and door obstruction detection pressure could be adjusted as required.
