NOTE: If an emergency situation arises during any operation, use the large red
mushroom EMERGENCY STOP button located on the control panel to shut down
the machine.
The PLC operator interface is used in all four operating modes:
1. Manual Mode – permits the operator to control all machine functions using the pushbuttons, as well as the
operator interface function keys.
2. Single Cut Mode – permits the operator to enter part length, and then advance and cut a single part automatically.
3.
Automatic Job Mode – is used to automatically cut a ‘job’ (a preset quantity of identical parts).
4. Automatic Que Modes – there are two alternative Que Modes, selectable by changing a PLC parameter.
•
Automatic Queue Mode – is the standard queue mode. It is used to automatically cut up to five different
jobs, consecutively, from a single workpiece or bundle. When all jobs in the queue are completed the saw
shuts down.
•
Multi Queue Mode – is used to repeat the same queue a preset number of times. This mode is primarily
used to cut parts in sets. To illustrate, consider cutting four pieces each, of three different parts, A, B,
and C. In the Auto Queue approach, each job is programmed with required quantity of 4. In multi Queue
approach, each job only has a quantity of 1, but the queue required is set to 4.
Auto Queue: A, A, A, A, B, B, B, B, C, C, C, C
Multi Queue: A, B, C, A, B, C, A, B, C, A, B, C
The same number of parts are cut, but Multi Queue procedures the parts in sets, and the first complete set is available
much sooner if large quantities are being cut.
