41. 990302 Change Note Ref 0626 Date 2 March 1999 Introduction Hecently it has been found that some makes of microcontrollers produce a solenoid failure message when used on HFO ventilators This is because the solenoid failure detection circuit connected to one of the controller inputs does not adequately pull the input to zero The 80C32 sources a 1 to 0 transition current of 650mA at 2V For a similar reason it is necessary to change the solenoid failure detection circuit for an SLE2000 Ventilator Modification procedure for A0702 boards on the SLE ventilators Connect a diode 1N4007 in parallel with R34 with its cathode ve connected to the drain of QA IRLU110 on all A0702 boards Additionally if the ventilator is an SLE2000 then change R32 to 8k2 and R34 to 91k 0 25W 196 Metal Film Rationale The diode will be reverse biassed when Q4 is turned off When Q4 is turned on it has a value of Rds of 0 5W giving a Vds of lt 0 1v The diode voltage is added to this which shall result in the microcontroller i p being pulled down to 0 8v Page 106 of 120 Circuit Diagram changes SLE 2000 changes E E INA007 i R34 Ni P PLE Sa kb alls N4007 ie De Ge LB 6a0 6 Q4 IRLU110 U10D R23 m S 15 Se AIRWAY 74AC540 4 RIGGER CIRCUI D4 A S INA148 PLB 23b LB 4a b SEE LI
