If the buckle chute home position sensors B01/02
malfunction, the stopper goes farther than the
home position until it stops at the lower limit and
overloads.
Then, circuit protector is actuated.
Check the followings:
1. B01/02 are installed correctly.
2. When a ferrous object is put on the detecting
part of the B01/02, the sensor LED illuminates.
3. At the same time, LED L3 or L6 illuminates on
QPM192.
4. Wiring and connection between B01/02 -
QPW422 - CON1/CON2 on QPM192 is OK.
Buckle stopper stops at the upper limit.
A set of sensors on the encoder P.C.B.
QPW422 malfunctions.

The couble of optical sensors on the encoder
P.C.B. QPW422 read and counts the rotation. If
the sensor malfunctions and they can not count the
rotation, the stopper goes father than the set
position until it stops at the upper limit. Then, the
circuit protector is actuated.
Check the followings:
1. Installation of the QPW422
2. Installation of the sensor plate
3. When the sensor plate is rotated manually, the
LED L1 and L2 or L4 and L5 on QPM192
illuminates by turns.
If the sensors malfunction, replace the sensors and
QPW422 together.
