Detailed Answer
ASRS maintenance mode: 1. Maintenance staff enter the storage area holding the remote; 2. Safety interlock (automatic operation disabled in maintenance mode); 3. The remote manually controls the stacker crane (low speed); 4. Two-person work (one operates, one supervises); 5. Exit maintenance mode when done. The LDER LD series PLC interface supports maintenance mode; XINGJIA likewise.
