Solution
16-1
The nozzle of
electrolyte SIP
abnormal
SIP nozzle
fails to reach
the bottom
Malfunction 1
：
Motor stops or fails to leave the top
(1) Check whether both ends of connector of the
motor are connected well.
(2) Check whether the conductivity of the motor lead
wire is good.
(3)check motor drive circuit of sample reagent disk
circuit board
(4) Inspect whether the rise and fall zero light sensor
is working well.
Malfunction
2：
The motor swing to the required
position, but the signal is not detected by the light
sensor.
Solution：
Manually enable the unit repeatedly rise to
top, transfer the multimeter to DC, negative points, 3rd
core of plug P142, positive point ,2
nd
core of P142
plug.
1.If the value of multimeter changing between 5 V
–OV, the light sensor and the wire is working
normally.
（1）Check the wire
Check whether the conductivity of probe light sensor
（P142）to wire J2 of ISE circuit board is good and
both ends of connector are connected well.
（2）Check the light sensor input circuit of sample
reagent disk circuit board.
2. The value of multimeter is not changing.
（1）Check the wire
Check whether the 1.2.3 core of P142 plug is
connected well, and whether the two ends connected
well.
（2）Check light sensor signal
