Repair of PCS Praxis Control Levers
The throttle control lever (Control Lever) in the Mega-Guard Propulsion Control System (PCS) by Praxis Automation Technology is a control element designed for remote control of the vessel’s main engines and thrusters. The lever transmits commands to the control system, which provides engine start, stop, and reverse functions, as well as setting thrust parameters (engine speed or propeller pitch).
In the event of a firmware failure or damage to the microcontroller bootloader, the throttle control lever could become completely inoperable. The device would remain in boot mode and would not accept commands from the operator. Installation and updating of the manufacturer’s software became impossible.
In practice, this led to the need for complete replacement of the unit, leaving the vessel without remote propulsion control and increasing repair time and cost.
Specialists at Dontechcenter have developed and implemented a technology for the complete restoration of Mega-Guard PCS Praxis Automation Technology throttle control levers.
- • Development and implementation of a new microcontroller bootloader for Mega-Guard PCS Praxis Automation throttle control levers;
- • Restoration and reprogramming of the bootloader using the developed solution;
- • Correct exit of the device from boot mode without removal from the vessel, provided the hardware remains intact;
- • Installation and verification of the original software from Praxis Automation Technology;
- • Verification and restoration of communication between the lever and the propulsion control system;
- • Full testing of all operating modes: start, stop, reverse, thrust parameter adjustment, and emergency modes.
The technology has been tested on real marine equipment and has been incorporated into the standard repair process for throttle control levers.
Dontechcenter provides the following capabilities:
- • Restoration of the existing device functionality without replacement in most cases;
- • Reduction of vessel downtime through on-site repair and reprogramming;
- • Comprehensive inspection of the throttle control lever, including mechanics, position sensors, software, and communication with the control system.
If issues occur with the Control Lever of the Mega-Guard PCS Praxis Automation Technology system, including unstable thrust, errors during lever movement, or failure after unsuccessful firmware updates, you may contact Dontechcenter. The company performs both traditional equipment repair and software restoration.
