：Rinsing mechanism can reach the top,
but can not check the zero position.
solution：Manually make rinsing mechanism repeatedly
rise to peak, transferred the multimeter To DC, plug the
negative point of the first three core P02, P02 plugs are 2
pole core.
1、Multimeter readings between the positive changes in
5V and 0, indicating coupler, lead normal
1) Check conductorsCheck 1,2,3 P02 core plug is
connected well and good connections at both ends is
connected
2) Check the reaction plate coupler circuit board part of
the circuit signal input
2、 No change on multimeter reading
1) Check conductors
Check 1,2,3 P02 core plug is connected well and good
connections at both ends is connected
2) Check the coupler signal
Check voltage between P02 plug 1,3 feet, if the voltage
is not 5v, check the connection plug is connected good. If
the voltage is 5v, check the J02 socket 2 feet of potential,
rising to peak when the potential was high, or low
potential. If the potential is not normal, check the coupler
Malfunction 3：Rinsing mechanism can not reach the zero
position.
solution：Mechanical repair
3-2
Rinsing
mechanism
abnormal
Rinsing
mechanism of
reaction cup
fails to leave the
top when
descending.
Enter into system maintenance window and execute
“Mechanical movement check”. Observe the
running status of stirring rod.
Malfunction 1：stirring mechanism doesn’t move
Solution:
1, Check stirring mechanism up-down movements,
mechanical repair is required if resistance is big.
2, check whether both ends of connector of the motor are
connected well.
3, check whether the conductivity of motor lead wire is
good.
4, check the motor drive module of circuit board is
