Product Description

AC C20 & AC 600 (propulsion control system), K-Thrust 600, K-Steering 600, K-Chief 500 and K-Chief 600 (alarm, monitoring and control system inclusive generator power management system) for AMS, ACC, ACCU and ABCU Classed Vessels and BWMS-C20 ( Bridge Navigational Watch Alarm System ) for NIBS and NBLES Classed Vessels. , It includes L2C (LAN to 2 CAN gateway), PB4 (Push Button 4), TMI (Torque Motor Interface), RFU MKII (Rudder feedback unit) and PB4, a push button panel including four switches with back-light and four LEDs. It is intended for use in K-Thrust 600, K-Steering 600 and AutoChief. , The purpose of the Common Thruster levers are both individual and common control of the thruster/propulsion/rudder units. , There are four main types of levers e.g. Azimuth, Single, Dual and Mini Wheel that each can be delivered with- or without integrated display. All levers have a main controller and a backup controller. , Additionally, they are equipped with electric shaft motors, buzzer, emergency stop and backup activation buttons., , Additional information with detailed list of assemblies and sub-assemblies is provided on an additional information sheet.
