Solution:
1. When the instrument is working, the syringe pump
doesn’t work
(1) Check both ends of the mechanism’s motor are
connected well
(2) Check thec conductivity of the motor lead is well
(3) Check cicrcuit board’s motor drive lead

Solution:
1. Observe the moving status of the syring pump while it’s
working
(1) Check both ends of this mechanism motor are
connected well
(2) Check the conductivity of the motor lead is good or
not
(3) Check circuit board’s driving motor
2. While the instrument is working, if the motor is
working ok, and it can leave the photo sensor position
(1) Check whether the photo sensor is in good condiction
(2) Check the conductivity of the lead connects the photo
sensor and the power adapter plate is good or not, check
both ends of the connector are connected well or not.
(3) Check the signal of the photo sensor
Check voltage between P043 pin plugs 1,5, if the voltage
is not 5v, check the plug P043 is in good connection; if the
voltage is 5v, check the potential of P043 4-pin socket.
While the pump is back to zero (vomiting), then the
potential is high, if not, the potential is low. If the potential
is normal, check the adapter plate; if it’s abnormal, check
photo sensor.
