ALARM (red) This lights if a hardware error occurs, or if operation slows
because of the program, and the watchdog timer is activated.
1.6.1.2 Initialize/Test Switch
Switch
position
Operation mode
INITIALIZE
(upward)
In the PROG. mode:
The contents of the operatio
n memory are initialized. However,
the system register (including the I/O map) and the program
are not initialized. If the error of self-
diagnostic error code 42 or
lower is occurred, the special internal relays R9000 to R9008
and the special data register DT90000 are not cleared.
In the RUN mode:
Operation errors, remote I/O system errors, and battery errors
are cleared.
(center) The switch should normally be left in this position.
TEST
(downward)
Setting this switch to the downward position in the PROG.
mode, accesses the test mode. Switching to the RUN mode in
this status, initiates test operation.
To return from the test mode to the normal operation, return
this switch to the center position in the PROG. mode.
1.6.1.3 Mode Selector
Selector position
Operation mode
RUN (upward) This sets the RUN mode. The program is executed, and
operation begins.
REMOTE
(center)
This enables operation to be started and stopped from a
programming tool. At the stage where the selector is
changed, when switching from the PROG. to the REMOTE
mode, the system remains in the PROG. mode and when
switching from RUN mode to the REMOTE mode, it remains
in the RUN mode.
PROG.
(downward)
This sets the PROG. mode. In this mode, programming can
be done using tools, the test operation mode can be
accessed and the operation memory can be initialized using
the initialize/test switch.

2 Conveyor Belt
2.1 Architecture and Function
l The main function of the conveyor belt is to transport the PCB and complete the
loading/unloading operations. Long term operation of the machine platform may lead to the
conveyor belt not being fully set on the drive axle, so users are advised to check that the
front and back conveyor belts are set properly on their axles before beginning operations to
extend the service life of the conveyor belt; if the belt needs to be replaced, first fit the belt
on to the drive axles on both ends before fitting it in order over the inner axles.
2.2 Sensor Adjustment and Replacement
1. Sensor 1 & 4 (Loading/Unloading Sensor): use the adjustment rod to adjust the Sensor
sensitivity until the indicator light is lit. (If there is an obstruction over the Sensor, the indicator
light will be lit, if there is no obstruction over the Sensor, the indicator will be off.) Then
gradually reduce it until the indicator light goes off. This will be the optimal sensor status for
Loading/Unloading.
2. Sensor 2 & 3 (Brake and Stop Sensor): adjustment method as above, but the LED light base
must be moved into position above the Sensor to check if the LED light base will interfere to
cause faulty operation. If interference does occur, the Sensor’s sensitivity needs to be
reduced until it is no longer affected by the LED light socket but still able to sense the
candidate board.
3. Sensor 5 & 6: (Holder Motor Sensor): Lowers the holder mechanism to its lowest position
along with the Sensor as well. Move the Sensor upwards until the indicator light is lit, then
move it slowly downwards again until the indicator light goes off for the correct setting.
4. Replacement: If the Sensor is not working, then the Sensor’s sensitivity should be re-adjusted.
If it still does not operate, replace with a new sensor. Replacement Method: first disconnect
the Sensor connector, and then remove the Sensor. Attach the new Sensor then connect and
secure the Sensor’s connectors. Once replacement is complete, adjust as directed in the
adjustment method.
