6.1 Pressure Relief System
Problem
Cause
Solution
4. Air is not
constantly flowing
into the Low Air
Loss Coverlet or
inside the
mattress
The internal pump gives priority to the
air cells in the mattress. Once the air
cells are inflated to the set pressure,
air will then be directed to the
coverlet or mattress.
Allow air cells to reach set pressure.
5. Display readings
appear scrambled
Power surges can cause the
controller to temporarily malfunction.
Disconnect power cord for 10 seconds, plug in
again to reset. If unsuccessful, call Tridien
Customer Service at 800-474-4225.
6. Every other air
cell is deflated
Controller is in AP mode
This is the normal function while in this mode.
7. Power loss
Facility power outage, blown fuse, or
possible internal damage.
Our unique design will close each valve,
preventing air loss for a short period of time.
a) See Section 5.1.1 Fuse Replacement
b) Call Tridien at 800-474-4225.
8. Patient is
uncomfortable or
mattress feels
lumpy
Excess or insufficient pressure.
a) Make sure controller is plugged in and
turned on, i.e.: LED is on and solid green.
b) Verify weight setting in Patient Setup. See
Section 4.4.2. Adjust if set weight is not
accurate to the patient’s actual weight.
c) Activate Fowler mode on Control Panel
(See Section 4.2 or 4.2.2 & Figure 11)
d) Incline head of the bed frame slightly.
9. Controller is
inoperable
May be caused by a power surge
substantial enough to overload the
internal circuitry.
May be caused by other internal
damage/failure.
a) Check fuse on power cord socket by
opening the fuse compartment on side of
controller.
b) See Section 5.1.1 Fuse Replacement
c) Call Tridien at 800-474-4225.
10. CPR hoses
become
disconnected from
exterior CPR
block
Excessive force applied to hose
connections.
Reconnect in correct orientation. See Section
4.5.
