5-14-1. Replacing the AWC Motor

1) Disconnect the connectors of the motor relay cable.

2) Loosen the set screws e on the motor bracket d to detach the drive belt from the motor pulley

3) Loosen the motor set screws g to detach the motor c.

4) Detach the motor pulley f from the motor.

5) Reassemble the components in the reverse order of steps 1) to 4). At this time, assemble the

components so that the end face of the motor shaft is aligned with the end face of the pulley f.

6) Adjust the tension of the drive belt.

• Belt tension adjustment procedure

Measure the tension at the center of the belt (see the Figure below) with UNITTA's belt tension

meter.

c Values to be input to tension meter Weight: 002.5

Width: 009.0

Span: 0133

d Adjustment value 25± 2.5N⋅m

5-14-2. Replacing the AWC Origin Sensor

1) Loosen the screw d. Detach the AWC origin sensor from the AWC origin sensor bracket c and

replace it with a new one.

2) Assemble the AWC origin sensor so that the clearance between the AWC sensor dog e and

the AWC origin sensor becomes 1 mm.

5-14-3. Replacing the Transport Stopper Interference Sensor

1) Adjust the clearance between the sensor dog and the transport stopper interference sensor to

1 mm.

2) Sensor dog assembling position

Narrow the transport width and gradually bring the sensor dog nearer to the transport stopper

interference sensor. After the sensor is turned on (i.e. the LED goes on), move the dog another

1mm in the direction indicated by the arrow, and fix it there.

5-15. Replacing the Barcode Reader

(On-Demand Production, Option for SCS)

(1) Functions

The barcode reader of the transport unit reads the 1D-barcode of the PWB and transmits the

results to the cPCI-8994 PCB through the RS232C.

(2) Meaning of LED

No. Name Function

LASER ON LED Lit when the laser is output.

OK/NG LED

• Lit in green when the OK signal is output.

• Lit in red when the NG signal is output.

TIMING LED Lit when the timing input is ON.

STABILITY LED

Indicates the reading stability and operation status of the main

unit. (See also the Table below.)

TEST switch The following operations can be performed with this switch.

• Test mode is started.

• When this switch is pressed instantaneously (2 sec. or less),

the BL-600-series reads the barcode only once.
