2203961Programmable Logic Controller
Dimensions Drawing for 2203961

Intended for use on all-terrain machines, our programmable logic controller is of robust design to operate in hostile environments (temperature, moist atmosphere, impacts, vibrations, etc.) It has been programmed to relay orders to the proportional distributor(s) swiftly by using the input data supplied (cylinder linear sensors), the instructions provided (display screen, steering wheels, joystick…) and the data from its built-in computer program.
This type of micro-controller is very responsive. It features physical inputs and outputs which are pre-wired with pre-swaged connector halves.

Screen Display

The screen display allows for Human-Machine Interface (HMI) and communication with the logic controller in order to modify the selected settings. Without screen, it is only possible to communicate with the logic controller by the attendance of a qualified programmer.

The screen display offers four configuration modules:

  • HMI (Human-Machine Interface) for the settings
  • Visualization
  • Diagnosis
  • Manual steering control

The HMI module gives direct access to the selection settings for the transmitters and cylinders by activation or deactivation; it makes it possible to act on the parallelism of the cylinders by increments on the boat steering, etc. With a private code (secret code), it also gives access to additional settings such as zero relative bearing, adjustment of the transmitters response angle, maximum rudder angles, lock to lock speed adjustments, decelerations, etc.

The visualization module allows viewing the rudder angles and parallelisms in real-time. It also displays the maintenance schedule of some elements in the system (oil change, filter replacement…) and conveys the alarms (oil level, temperature, filter clogging…) in the form of graphic and/or buzzer.

The diagnosis module allows carrying out a global inspection before starting by testing individual elements in order to identify and isolate the possible failure of a system component and it verifies the supply voltage in real time.

The manual steering control module makes it possible to steer the boat via the display screen keys, thus a substitute for the transmitters.

Transmitters

Electric Wheel

2203400Electric Wheel (2.5 turns)
Dimensions Drawing for 2203400

With this sturdy designed electric wheel, it takes 2.5 turns for the cylinder(s) to travel their full strokes. The electric wheel is affixed with three screws behind a bulkhead and is connected to the electric harness with an identified, pre-swaged connecting pin.
It is equipped with a standard conic shaft end. To be used only on single steering station installations with a steering wheel.

Electric Wheel 2.5 Turns

2203287540° Electric Wheel (1.5 turn with automatic recentering)
Dimensions Drawing for 2203287

With this sturdy designed electric wheel, it takes 540° (1.5 turn) for the cylinder(s) to travel their full strokes. The electric wheel is affixed with three screws behind a bulkhead and is connected to the electric harness with an identified, pre-swaged connecting pin. It is equipped with a standard conic shaft end. Thanks to the automatic recentering function, it can be used for twin steering station installations with two steering wheels.

2203403 Angular Control

This angular control makes it possible to maintain a selected angle to port or starboard by increments of 10 degrees, without having to operate the lever continuously. Easy to install, of sturdy design, its operation is intuitive.

2203288 Proportional Joystick

Designed to monitor work functions on mobile machinery, this joystick is particularly robust. Featuring centre spring return and digital outputs (CAN), up to four units can be installed at different locations on the boat. Its protection rating corresponds to IP66/67. It also features non-contact detection (Hall Effect) and user-friendly lever ergonomics. Its proportional speed control makes it possible to increase or decrease the cylinder travel speed in function of the lever displacement speed.

2203296 Selector Knob

When the installation includes several transmitters (steering wheel(s), joystick(s)…), the selector knob is pressed to select the transmitter to be used. It then produces a green light and disables all other transmitters.

Hydraulic Piping

The hydraulic piping represents all the hydraulic flexible tubes linking together the hydraulic components (power pack, by-pass valve, cylinder…). Its definition depends on the number and type of steering system components and on the distances between these components.

It also depends on the configuration of the hydraulic diagram.

Electrical Harness

The electrical harness consists of all electrical wires connecting the transmitters and receivers to the programmable logic controller. Its definition depends on the number and type of steering system components and on the distances between these components and the programmable logic controller.

Each wire is fitted on both ends with paired pre-swaged connector halves.
