It is connected to the control unit via a 14-core cable terminated by a 13-pin DIN connector. The ACP panel is connected directly to the control unit.

  • Page 16: Left And Right Side Rail Limit Switches (Emr Ready Only)

    3.7.1 Left and right side rail limit switches (EMR ready Only) The limit switches serve to detect the current position of the side rails. If the side rail is in the up position, the limit switch is pressed via the mechanism of the side rails and a signal is sent to the integration module and vice versa. Limit switches are not separately connected, Left and right limit switches are in serie.

  • Page 17: Weighing Sensor (Tensometer)

    Weighing sensor (tensometer) According to the load, the electrical resistance in the weighing sensor changes. The change is transmitted immediately to the weighing module, which processes the values. There are four weighing sensors (tensometers) on the bed – 2 at the feet and 2 at the head. They are secured using eight screws (6±2 Nm). The weighing sensors are connected to the weighing module by a 4-core shielded cable.

    Lift drives - Columns The lift unit does not have limit switches. It is connected by a cable with an eight-pin connector. The maximum current consumption is 5.5A and maximum working voltage is 24V. The value of the consumed current and supply voltage is displayed at LINIS.

  • Page 23: Undercarriage Module (Um)

    Undercarriage module (UM) The undercarriage module (hereinafter UM) allows all peripherals located on the undercarriage to be controlled and integrates the control of these peripherals via the control unit. The UM is connected to the control unit by a 4-core communication cable with Molex connectors. This cable carries power and digital data simultaneously.

  • Page 24: Undercarriage Module - Basic

    Undercarriage module – Basic The bed with basic equipment (e.g. without iBrake, Anticrash, etc.) is equipped with elementary undercarriage module. The output from undercarriage module is molex connector which is connected to the column and after to control box. Foot controller (height setting) The foot controller for height setting is a paired component of the bed.

  • Page 25: I-Brake

    I-Brake The I-Brake is a device allowing automatic braking of unbraked beds after they have been connected to the mains. I-Brake automatically brakes a bed within 60 s after it has been connected to the mains. If the brake is deactivated mechanically (for example, during cleaning), the system brakes the bed again.

  • Page 26: Night Illumination

    Night illumination The control unit allows a pair of illuminating "white" LEDs to be connected, ensuring illumination of the mattress platform. The night illumination (LEDs) are connected via a ribbon cable to the control unit. Safe Stop (Anticrush) Safe Stop prevents user of the bed from injuries due to crushing by the lowered Mattress Platform. When obstacle occurs on the undercarriage and Mattress Platform is going down, the motion is automatically stopped.

  • Page 27: I-Drive - Driven 5Th Castor

    i-Drive - Driven 5th castor The bed may be fitted with a driven i-Drive Power wheel to help hospital personnel move a bed with a patient on it while applying only minimum force. The driven castor i-Drive Power is located in the middle of the bed’s undercarriage. Using the i-Drive’s servo mechanism, the i-Drive is lifted according to the operator’s need or dropped and forced against the floor in a way that it is possible to use the castor's torque to make it easier to move the bed in a straight direction.

  • Page 28: I-Drive Control Panels

    3.20.3 i-Drive control panels The i-Drive is activated by the activation panel, which is on the bed’s undercarriage and protrudes from the cover of the undercarriage. Activation panel of i-Drive with buttons ON (activation of i-Drive is active for 3 minutes, extension from last selected function) and button OFF for lifting the driven castor.

  • Page 29: Emergency Button To Retract The I-Drive

    3.20.4 Emergency button to retract the i-Drive The emergency button for lifting the driven castor serves as a safety feature in situations where, for example, the standard button for lifting stops functioning or the I-Drive battery is fully discharged. The button is in the middle of the control unit fixed on a holder.

  • Page 30: Correction Of Voltage On I-Drive

    3.20.7 Correction of voltage on i-Drive The voltage on the driven castor is corrected both to protect and for greater ease of use. To protect the i-Drive, its voltage is corrected so that the current does not exceed approximately 29 A. For more direct movement over an inclined surface, the voltage is corrected according to the tilt of the bed measured by the accelerometer.
