Check voltage between P142A plug pin 1，3, if the
voltage is not 5v, check the connection of plug. If the
voltage is 5v, check potential of P142 plug pin 2. The
potential is high when reaching to the top position,
otherwise the potential is low. If not normal, check
the light sensor

16-2
The nozzle of
electrolyte SIP
abnormal
SIP nozzle
fails to reach
the top
Malfunction
The motor stops or fails to leave the
bottom.
(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
The motor swing to the required
position, but the signal is not detected by the light
sensor.
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.
