D The remote control system (RCS)
D The electronic speed control system
D The safety system
D The telegraph system
Note: The safety system and telegraph system operate independently and are
fully operational if remote control functions become defective.
5.2 Remote Control System
The remote control system (RCS) has the primary functions that follow:
D Start, stop and reverse
D Automatic slow turning
D Auxiliary blower control
D Transfer control
D Speed setting
