Alarm
Code
Description
Detailed
description
Solution
4-1
Reaction
disk
abnormal
Reaction disk fails
to rotate to the
designated
position.
Malfunction：
The quantity counted by reaction cup light
sensor does not conform to real quantity of cup rotated.
solution：Check whether the signal status of counting light
sensor is normal.
（1）check whether the conductivity from counting light
sensor 1 to lead wire is good.
（2）check whether the counting light sensor 1 is ok.
（3）Check input part circuit of reaction disk circuit board
light sensor signal.
4-2
Reaction
disk
abnormal
Reaction disk fails
to stop at the
designated
position
Malfunction
：
Reaction disk fails to stop at the position
matching with light sensor.
solution：the same as 4－1
4-3
Reaction
disk
abnormal
Reaction disk fails
to stop at the zero
position when
resetting.
Malfunction
：
Reaction disk fails to stop at the zero
position after resetting or the light sensor of zero position
did not check resetting point.
solution：Check whether the signal status of counting light
sensor is normal.
（1）check whether the conductivity from zero light sensor
to lead wire is good and the both ends of connector are
connected well.
（2）check whether the zero light sensor 1 is ok
（3）Check input part circuit of reaction disk circuit board
light sensor signal.
