ROL Ergonomics LogicB-4-ROL-BOS-WMCO-500-360VA motor controller unit

LOGICB-4 is a motor control unit for height-adjustable electric desks based on the LOGICDATA LogicB-4 / LogicB-5 platform. The controller supports multiple motors and provides safe and reliable desk height adjustment for professional and office use. The unit features Intelligent System Protection (ISP), automatic motor detection, and support for memory and safety functions with compatible hand controls.

Features (according to manufacturer data, adjustment will most likely require some sort of a programming device):

• All Logicdata hand controls are optionally usable.
• Depending on the hand controller type, additional functions are available, such as saving and using memory locations.
• ISP (Intelligent System Protection)
• Configurable stop conditions (over temperature, over current, timeout, limit switches).
• Configurable reset conditions.
• Configurable duty cycle.
• Mains cut-off with configurable turn-off time.
• 2 freely definable motor-groups.
• Automatic motor detection.
• Plus detection
• Up to 6 memory positions.
• Additional pinch-protection with optional squeeze line.
• Lock function with PIN code.
• Drive-back function on various conditions.
• Auto-move function.
• Flex memory with random function.
• Sit-stand memory.

Note! The controller requires 4 legs to operate, or an alternative way to trick the controller/reprogram it if fewer legs are used.

• Configuration from the factory:
  • LOG-PAR-MCBA-4-ROL-BOS-500-340VA Rev1
    • Configuration explanation as best as we can interpret:
      • LOG
        • LOGIC / LogicBox / Logic controller refers to the entire control system (Rol Ergo Logic series)
      • PAR
        • Parameterized / parameter version meaning the software or configuration is parameterizable, can also mean “parent board” / main controller
      • MCBA
        • Main Control Board Assembly main PCB
      • 4
        • number of channels / motors in electric desks this is often:
          • 2 = basic desk
          • 3...4 = multiple legs / memory controls / additional devices
