8. MJB2 (MEDLINE
®
CARELINE
®
)
The MJB2 is a compact 2-port repeater designed for use together
with analogue or OpenBus™ control boxes. It is optimised for use
in systems where 1 extra port is needed for easy connection of a
hand control, a foot switch or an accessory like the UBL. It is easy to
integrate in a wide range of healthcare applications such as hospital
beds, surgery tables, and treatment chairs.
Recommendations
• Always use locking mechanism and O-ring.
• Unused socket(s) must be fitted with blind plug(s) to ensure the IP degree.
• When mounting, a screw torque 0.8-0.9 Nm is recommended.
• Hot-plugging: removing or adding any OpenBus™ cables is not allowed when the control box is powered by mains supply.
If still required, follow this procedure:
1. Remove mains and wait for 5 seconds
2. Connect or disconnect the required cables
Non-observance of this procedure may lead to a damaged OpenBus driver curcuit.
The risk of a damaged circuit increases, if the accessory shows a high starting current or inrush current.
Warnings
• Using a wrong type of MJB2, for instance 10 wires in an OpenBus system, can lead to unintended movement or no movement.
• Using wrong screws or the wrong torque can lead to cracks in the housing.
• The cable is not to be exposed to high pull force or sideway traction.
