Preface

Important information

WARNING

Although your ST40 instrument is designed to give accurate and reliable performance, it should serve only as an aid to navigation and should never lead to the erosion of good seamanship. Always maintain a permanent watch and be aware of situations as they develop.

EMC conformance

All Raymarine equipment and accessories are designed to the best industry standards for use in the leisure marine environment.

The design and manufacture of Raymarine equipment and accessories conform to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised.

Handbook information

To the best of our knowledge, the information in this handbook was correct when it went to press. However, the Raymarine policy of continuous product improvement may change product specifications without notice. Consequently, unavoidable differences may occur between the product and the handbook from time to time, for which Raymarine cannot accept liability.

Chapter 1: Operation

1.1 Introduction

Your ST40 Wind instrument:

• Provides apparent wind speed and direction information. Wind

speed units can be either knots (KTS) or metres per second (M/S), as set during User calibration (see Chapter 4, Calibration).

• Provides true wind speed and direction information, if boat speed information is available on SeaTalk.

• Enables a locked apparent wind angle to be defined either manually, or automatically by a course computer. In this mode, the instrument shows the deviations from the locked wind angle and the direction to steer to achieve the locked wind angle.

CAUTION

Your instrument is calibrated to factory (default) settings when first supplied and must therefore be calibrated before use, to ensure optimum performance on your vessel. Do NOT use the instrument until the calibration procedures have been satisfactorily completed, using the procedures in Chapter 4,

Calibration.

Coloured bezel and Desktop Mounting Bracket options are available for your ST40 instrument. Contact your Raymarine dealer for further information.

1.2 Operating procedures

Operating information is presented in flow chart form. The flow charts show the various operating screens and key presses necessary to carry out the various instrument functions. Key presses are momentary unless otherwise stated.

Silencing alarms

To silence an alarm (see the Alarms section, later in this chapter), momentarily press any one of the instrument keys.

1.4 High wind speed alarm

The high wind speed alarm threshold is set up at the Set high wind speed alarm threshold screen and the alarm sounds if the alarm is

switched on and the wind speed exceeds this threshold.

Chapter 1: Operation

Indications

ST40

WIND

True wind

If boat speed information is available at the ST40 Wind instrument (from a SeaTalk bus), the alarm is triggered if TRUE wind speed exceeds the threshold.

Apparent wind

If boat speed information is not present, the alarm is triggered if the APPARENT wind speed exceeds the threshold.

Enabling/disabling alarm

You can enable or disable the high wind speed alarm function (i.e. switch it on or off ) by selecting the Set high wind speed alarm threshold screen (see Normal operation) and holding down the key for 3 seconds (toggle action).
