PREFACE
INTRODUCTION
Jastram’s Digital Steering Control system provides an advanced form of
rudder position control for a wide variety of vessels and ships. The Digital
Steering Control system consists of five basic components:
• The main Digital Steering Controller
• At least one Mode Control Processor
• At least one steering input device
• A rudder feedback unit
• A steering gear hydraulic power unit
The main Digital Steering Controller can communicate with up to five
Mode Control Processors installed at various locations on the vessel.
Each Mode Control Processor can accommodate a wide variety of
steering input device options.
NOTE:
This manual assumes that the mechanical steering gear and the hydraulic
power unit have been successfully commissioned and tested prior to
application of power to the Digital Steering Control System.
AUDIENCE
Sections 1 and 2 of this manual provide a description, specifications,
installation information and commissioning information for each of the
inputs and outputs of the main Digital Steering Controller and the Mode
Control Processor. This information is to be used during the design and
layout of the vessels steering control system in order to select the desired
modes and locations of steering control as well as to determine what
ancillary devices may be required. Specific installation information is also
provided for those installing and connecting the equipment.
Section 3 provides a description of the system operation for each type of
steering mode and each of the configuration options. This information
provides vessel operators with a detailed description of how the vessels
rudder position will be controlled and how the overall system will be
operated.
Section 4 provides the information necessary to commission and calibrate
the steering control system.
