• Check whether it is the PLC that is not allowing the move.
The PLC may not allow a move if there is a board in the
machine or some of the sensors are triggered.
• Check that the conveyor rail is not on the AWA Limit sensors.
• Check the cabling of the motors.
Conveyor rails will not align properly
• Perform AWA calibration.
• Check that the left minimum sensor and the right alignment
sensor are in-line. This can be done by measuring and
comparing the distance from the sensor to the structure
edge.
• Check all sensors are working by placing something (for
example, a piece of card) at various parts of the rail to see if
it triggers the associated sensor/input.
• Ensure that when the AWA software is executing the aligning
operation, the relay KA2 is activated so as to allow the right
side motor to be moved.
• Check the cabling of the motors.
