maintenance" interface after on-line, implement
"mechanical movement check", and observe the
stirring rod running status
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
working normally
5、Check whether the it is at top position, check whether
up-down zero light sensor works normally at top position.
Malfunction 2
1、check whether the installation of left and right limit light
sensors is correct.
2、When the instrument is turned on, manually swing the
stirring mechanism to observe the left limit coupler, transfer
the multimeter to DC, negative points, 12 of the plug core
P02, P02 plug is the 11th pole core. .
(1) multimeter reading in is between 5V and 0 change,
indicating coupler, lead normal
1) Check conductors
Check whether the P02 plug 10,11,12 core well-connected, the
connection is connected at both ends of good
2) Check the reaction plate coupler circuit board part of the
circuit signal input
(2) multimeter reading of no change
1) Check conductors
Check whether the P02 plug 10,11,12 core well-connected, the
connection is connected at both ends of good
2) Check the coupler signal
Check voltage between P02 pin plugs 10,12, if the voltage is
not 5v, check the connection plug is connected good. If the
voltage is 5v, check the J02 socket 11 feet of potential, rising to
peak when the potential was high or low potential. If the
potential is not normal, check the coupler.
