Arkel KM-30S DC Elevator Door Control Device (Controller)

KM-30S Door Control Card

The Arkel KM-30S is a control card designed for 220V AC synchronous motor-powered telescopic elevator doors, providing smooth and efficient operation.

Functionality at a Glance:

• Full Door Control: It features outputs for door fully open/closed states and detects when a door is obstructed or if a safety edge is active.
• Relay Output: Offers relay contacts for maximum loads of 3A at 250VAC or 30VDC.
• Signaling Proficiency: The device processes door open/close signals, slow/fast signals, safety edge signals, and floor signals.
• Fire Elevator Compliance: The KM-30S door card is suitable for fire elevator doors, ensuring safety and compliance in emergency scenarios.
• Nudging Mode: With slow speed signal input, it can bypass safety edge signals for slow speed door closing during prolonged safety edge activations (Nudging mode).
• Diagnostic Display: In normal operation, the card displays door speed, position, and status. In the event of a fault, it shows the relevant error on the screen.

Technical Specifications

• Smooth and Seamless Operation: Advanced software allows for smooth transitions in movement with a unique algorithm that does not require limit switches for door operations.
• No Need for Limit Switches: Door widths and open/close positions are automatically detected, simplifying the installation process.
• Obstruction Response: When an obstruction is detected, the system alerts with an audible warning and reopens the door, preventing harm to passengers and the door itself.
• Authorized Access: Menu access is tiered for security and ease of settings adjustments with different levels of access from manufacturer to basic and restricted levels.
• Extensive Parameter Options: Allows entry of application-specific parameters like motor reduction ratio, motor speed, and drive pulley circumference for manufacturers.
• User Settings: Users can define speeds in cm/sec and set ramp distances in centimeters for precise control.
• Counter Support: An open/close counter tracks door operations for maintenance insights.
• Various Output Signals: Provides fully open, fully closed, and obstruction detected output signals for full integration with control panels.
• Keypad Programming: All system parameters can be adjusted using the KM-30S keypad.
• Reducer Option: Supports control of 220V BLDC door motors, with or without a gearbox.
