5.5 RC circuit
5.5.1 Function description and purpose
For improved safety reasons peripheral controls ( ACP, patient hand control, siderail controls and Mobilift) have been
fitted with RC components. These allow the control box to recognise whether a circuit activation is a valid press of a
button or a short circuit. In such a case, the function is blocked as protection against a short circuit. Short circuit
protection only works when all controls are fitted with RC components and the function is activated in the control box.
Multicare 2015 redesigned beds have short-circuit detection turned on by default.
All control units are equipped with switching on or off of the short-circuit detection function. Switching can be
achieved using the ACP.
NOTES:
- Peripheral controls which are equipped with an RC circuit for short-circuit detection are compatible with
control units with short-circuit detection turned ON or OFF.
- Peripheral controls which are not equipped with an RC circuit for short-circuit detection are not compatible
with control units with short-circuit detection turned ON and it is necessary to turn this function off in the
control unit.
- If there is one peripheral component which is not equipped with short-circuit detection (does not have an ST
or KA {SN 2014 and higher} mark on the ACP; or ST on the handset) it is necessary to turn off the short-
circuit detection.
- If the function is controlled by data transfer (head siderail, undercarriage module), then short-circuits are not
detected.
