6.2 Elevated pressure ulcer risk (sitting operation)
If the
Sitting
operation is continuously
switched on for more than 60 minutes, a
reminder of the elevated pressure ulcer
risk is given.
The LED row will light up as shown in the
figure. The LED for the information signal
reset button blinks and the display reads,
“Increased risk for pressure ulcers; check
function”.
Once the information signal acknowl-
edgement button is pressed, the visual
signal stops flashing. Press and hold down
the button for three seconds to acknowl-
edge the entire signal and have the de-
vice start operation from the beginning
with a new timer.
The information signal can also be ac-
knowledged by selecting another func-
tion from the controller.
6.3 Check the air tubes (leak in tube or inner cells)
The information signal reset button blinks
and the display reads, “Check the air
tubes. See the removable quick guide”.
This information signal is displayed if
the device does not achieve the desired
function of the active operation within
45 minutes. This may be due to a discon-
nected tube or a leak in the inner cell or
tube system, among other causes.
The controller is only able to detect defective inner cells according
to chapter 6.3. The defective upper cells must be identified by the
user according to the instructions stated in chapter 7.2.3.
The LED display is lit for that area of op-
eration where the controller has failed to
achieve the target pressure value for the
function. In this example, the issue has
been detected in the torso section of the
cell.
Perform the following tasks:
