ery unless a properly engineered control system is installed. WABCO control systems are de- signed on the concept of single han- dle control of all maneuvering oper- ations through a sequenced and in- terlocked control system, which in- sures that the proper operation of engines, clutches, reverse gears, and associated propulsion machinery is obtained without relying on opera- tor judgment to time or anticipate propulsion machinery functions. The flexibility and adaptability of pneumatic controls permits the in- stallation of multiple operating sta- tions with interlocked control trans- fer to insure that only one station can be in control at anytime. Rug- ged control components provide de- pendable operation under extreme operating conditions experienced in shipboard installations. The rela- tively uncomplicated component and control system construction fa- cilitates maintenance and service- ability, contributing to extended system life and low maintenance costs. Production control systems such as Gearmaster, Logicmaster Hy- draulic Clutch, and Logicmaster Air Clutch are available for standard engine reverse gear applications. They combine proven, high-per- formance WABCO Pneumatic com- ponents in factory-assembled, test- ed, and pre-adjusted control units to simplify shipboard installation. All components are sub-base mounted, where possible, for easy and convenient servicing. These sys- tems are generally applicable for installation up to 4,000 bhp per engine. Recent control techniques com- bine the advantages of electronics and pneumatics to provide high- speed, electronic signal transmis- sion from very distant remote sta- tions, converted to pneumatic power at the engine location to perform the normal interlocking, sequenc- ing, and positioning operations re- quired. WABCO's Helmmaster control systems combine the normally sepa- rate control levers for main engine/ propellers, bow and stern thrusters, and rudders into a single joystick control lever that can precisely con- trol vessel maneuvering.
