13. ed It does this by intermittently removing the pressure from the patient by sequentially deflating the supporting air cells of the mattress The Power Unit provides the source of energy to achieve this and also the necessary monitoring and control systems for efficient and safe operation In simple terms the air compressor delivers air to the solenoid valves controlling the flow of air into and out of the mattress air cells The pressure of the air within the mattress is continuously monitored by the solid state pressure sensor enabling the inflation pressure to be directly controlled and varied to achieve the desired comfort level The software based control system operates the solenoid valves to enable air to flow into or out of the air cells as required according to the operating mode selected It also maintains the air pressure within the air cells at the required level and controls the action of the alarm system in the event of mains supply failure or over or under inflation pressures occurring 3 1 2 Start Up When the Power Unit is switched on the Compressor starts running Air is sucked into the Compressor through Valve T and is delivered via the inlet and outlet filters to Valves P Q and R and hence to the three sets of interlinked air cells In parallel air is delivered directly to the two longitudinal Side Formers and to the three head end Air Cells to which they are connected The Display shows the message Please wait Adjusting Pres
