056357/B Chapter 5: Installation 5.1 Mechanical Installation The RAC is to be installed at a protected location. In most cases, it will be placed inside a bridge console or bulkhead mounted in the vicinity of the connected RAIs. Attach the RAC to a level surface with four M6 screws (or nuts and bolts).
056357/B Rudder Angle Feedback Unit Potentiometer WARNING Risk of injury Connecting the Rudder Angle Calibrator to a rudder angle feedback unit in parallel with the steering gear feedback loop bears the risk of malfunc- tion of the steering gear in case of wire breaks or short-circuits resulting in possible injury and/or damage.
Page 31
RAIS 056357/B Chapter 6: System Configuration DANGER Life danger through electrical shock Certain alarm devices may operate with hazardous voltages, switched by the alarm relay output contacts. During configuration, the Rudder Angle Calibrator must be operated with the housing open. Make sure that any external device or power supply connected to the alarm relay outputs is de-energized and safe- guarded against accidental switching-on.
056357/B RAIS 6.1 Initial system configuration Configuring the RAC with SUSI 1. If the RAC is currently powered up, switch off the power first. 2. Open the RAC housing and locate the USB service port receptacle, J3, on the PCB. Make sure that the port is freely accessible for plug- ging and unplugging the USB cable.

056357/B RAIS Input Calibration Table To compensate for possible misalignment of the feedback unit and non- linearity of the feedback potentiometer, the RAC permanently applies correction to the input value, according to a stored calibration table. The input calibration table contains a number of calibration points, each of which maps a feedback input value to the corresponding true rudder angle, as read from the rudder stock scale.
RAIS 056357/B General Remarks on Calibration With regard to the RAC in- and output calibration using SUSI, observe the following points: • Port rudder angles are displayed as negative numbers in SUSI. Accordingly, port angles must also be entered as negative numbers, prefixed with a minus sign.
At least three input and three output calibration points must be set to make the outputs become functional. Sperry Marine recommends to carry out an initial calibration directly after the basic configuration parameters have been set. During this initial calibration, input calibration points are to be set at the hardover and midships rudder positions.
Page 47
RAIS 056357/B To carry out the initial calibration: 1. If not already connected, connect to the RAC with SUSI now, as described in “Configuring the RAC with SUSI”, steps 1 through 12, starting on page 6-2. 2. Click on the “Calibration” tab of the Rudder Angle Calibrator applica- tion to enter the calibration page.
Page 48
056357/B RAIS 8. Read the exact rudder angle from the rudder stock scale and enter it in the input calibration rudder angle control: enter exact angle read from rudder stock scale 9. Click to set a new calibration point. 10. Put the rudder to the hardover starboard position. 11.
Page 49
RAIS 056357/B 14. At least three output calibration points must be set now before the calibration page can be quit and the calibration settings are written to the RAC. Note If no RAIs are connected to the RAC at this point in time, zero output val- ues may be entered as a temporary measure, to be able to finish the ini- tial calibration and transfer the calibration settings to the RAC.
Page 50
056357/B RAIS enter zero adjust output for exact (rudder midships) rudder midships indication In case no RAIs are connected to the RAC at this point in time, leave all output settings at the default value of 2048. 20. Click to set a new calibration point. 21.
Page 51
RAIS 056357/B Note In case dummy signals or zero values have been supplied during the in- or output calibration, the RAC may not be taken into operation yet. The configuration of the unit is not complete before the input has been calibrated using the actual input signal from the feedback potentiometer and the outputs have been calibrated for the individual RAIs installed.
056357/B RAIS Adding, Editing and Deleting Calibration Points After the initial calibration procedures, a performance check of the RAI system may reveal that the required calibration accuracy is not yet attained over the entire rudder angle range. This may happen especially if the feedback lever linkage is poorly aligned or the feedback unit’s shaft runs not exactly parallel to the rud- der stock.
Page 53
RAIS 056357/B To edit in- or output calibration points: 1. If not already connected, connect to the RAC with SUSI and enter the RAC application’s calibration page. 2. With the spin control, scroll down the list of existing calibration points to the point you wish to edit. 3.
056357/B RAIS Input Calibration using Dummy Values In some installations, it may be required to carry out the output calibra- tion before the input calibration. E. g., if the RAI system is installed and wired up, but the rudder cannot be actuated because the steering gear is not operational.
