ARKEL – KM 20

KM 20
Door Controller Cards

Door fully open / fully closed
Door jam or photocell active output
Relay contact output. For 3A, 250VAC or 30VDC
Door open / close signal
Slow signal / fast signal
Photocell signal
Ground signal
Active with 24VDC
Suitable for use on fire lift doors (High speed signal input can be detected)
The door can be fully opened, completely closed, and contact outputs with jam / photocell detection for fully integrated operation with the control panels
With slow speed signal input, the photocell signal is not taken into consideration in long time photocell cutting and the doors are closed at slow speed and with audible warning (Nudging mode)
General Features

Advantages of Using KM 20 SCR System
Motor Domination -> Full control of the motor with 4-zone motor control Advanced parameters for motor identification
High Comfort -> High comfort with true S softening on the navigation ramps
No Limit Shalter Required -> Serial door movements with limit switch unnecessary algorithm. Door width, door open-close positions are detected automatically
Battery and DC Supply -> It can work with 2 12V battery supply or 24VDC external power supply. The type of emergency feed is easily selectable with the jumper on the card
Card Support -> The acupuncture is made by the card. After emergency door opening with battery supply, the card will go to sleep, preventing the discharge of the pacemakers completely
Battery Charging System -> If the elevator is not in the door opening area with the floor signal, it is ensured that the doors are kept closed to the level of the floor in the cordless crawler systems
Possible Door Jam -> When the door is jammed, the buzzer is turned back on. The jamming is passed slowly through the perceived zone to prevent damage to the passengers and the door
Wide Parameter Capability -> For manufacturers, parameters such as motor reduction ratio, engine revolutions, drive pulley circumference, spoon opening zone, etc. can be entered for application flexibility
User Settings -> For user settings, defined speed settings in centimeters per second and defined ramp paths in centimeters can be specified
Variability According to Need -> Door open and closed holding pressure, door jam detection can be adjusted according to the need of the press
Isolated Inputs / Outputs -> Isolated inputs and relay outputs for fully integrated operation with control panels
Keyboard -> Detailed setting and status monitoring with KM-20 Keypad (Optional)
Delegation -> In terms of security, necessary needs and ease of setup, access to the menu has been authorized. Different levels of authority have been assigned to access the menu: producer level, basic level and restricted level
Counter Support -> Operation of the door can be monitored by the on/off counter
