Trouble-Shooting Guide - SPAN PressureGuard PROTOCOL Owner's Manual

Problem
In non‐powered mode, air
system appears to be
underinflated, overinflated, or
stuck in an alternating pressure
inflation pattern (two air
cylinders inflated, two cylinders
deflated).
System will not power up.
Note:
Always plug power supply into
properly grounded receptacle.
Patient not rotating /alternating
properly.
Mattress not inflating or patient
reports a feeling of "sinking"
into surface.
Low pressure indicator
illuminated.
Interference produced to
electronic equipment/devices in
surrounding area.
TROUBLE SHOOTING GUIDE
Technical Service: (800) 888‐6752
Possible Cause
Powered control unit was
disconnected from mattress in
mid‐cycle, without first resetting
the system via the "disconnect"
function.
The system is not plugged in.
There is no power at outlet.
Power cord is damaged.
Blown fuse.
System is not turned ON.
Patient not centered on mattress.
Patient has severe contractures.
Head of bed is elevated or knees
are gatched.
Defective control unit
Patient exceeds weight limit.
Control unit is not turned on.
Airlines not connected.
Airlines or quick disconnect
connectors are damaged.
Head of bed elevated.
Defective control unit (mattress
fills without patient, sinks with
patient weight).
Airlines not connected.
Airlines or quick disconnect
connectors are damaged.
Defective control unit.
Leaking inflation system.
Electromagnetic interference
caused by the unintentional
emission of electromagnetic waves
of energy. These waves are
transmitted through the air at
various frequencies which may
produce interference such as
abnormal functioning to nearby
electronic equipment.

Solution
Attach powered control unit and perform resetting function to
return system to ideal, non‐powered inflation level. See page 9.
Plug power cord into wall receptacle.
Restore power.
Call for service.
Call for service.
Plug power cord into wall receptacle.
Reposition the patient.
Rotating can be difficult to observe in patients with severe
contractures. Observe someone without contractures lying on
the bed for 30 minutes (approximately 2 cycles) to confirm
turning is functioning properly.
The degree of patient turn achieved is reduced with elevation of
the head of the bed or gatching of the knees. If HOB must be
elevated, alternating pressure is the more appropriate mode.
Call for Service.
Call Span‐America for assistance with product selection.
Turn control unit on.
Ensure secure connection of airlines at control unit and
mattress.
Call for replacement.
Lower head of bed and allow air to equalize. Return head of bed
to elevated position that is comfortable for patient.
Call for service.
Disconnect and reconnect airlines to verify they have all locked
into place.
Call for replacement.
Call for service.
Call for replacement. To replace, turn mattress upside down
and unzip cover. Remove inflation system, install new system,
zip cover and restore mattress to upright position.
Determine if emissions are causing the interference by turning
the equipment off and on. If the interference in the affected
device subsides when control unit is off, proceed with the
following steps.
a) Reorient or relocate the affected device.
b) Increase the distance between the equipment.
c) Connect the equipment into an outlet on a circuit
different than that of the affected device.
d) Consult the field service technician or manufacturer of
the affected device.
