1 Chapter 1: Operation Chapter 1: Operation Your ST40 Depth instrument: • Provides depth information, in either feet (FT), metres (M) or fathoms (FA), as set during User calibration (see Chapter 4, Calibration). • Records the minimum depth encountered during the period it is switched on. You can reset this at any time. • Enables you to define alarm thresholds for shallow water, deep water, shallow anchor and deep anchor. • Enables you to see what offset is applied to the depth reading.

7 Chapter 2: Maintenance and Fault Finding Chapter 2: Maintenance and Fault Finding 2.1 Maintenance Servicing and safety • Raymarine equipment should be serviced only by authorised Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user-serviceable parts in any Raymarine product. • Some products generate high voltages, so never handle the cables/ connectors when power is being supplied to the equipment.
8 ST40 Depth Instrument Owner’s Handbook Instrument Certain atmospheric conditions may cause a small amount of condensation to form on the instrument window. This will not harm the instrument and will clear after the instrument has been switched on for a short period. Periodically clean your ST40 instrument with a soft damp cloth. Do NOT use chemical or abrasive materials to clean the instrument. Transducer Refer to the Installation and Maintenance instructions supplied with the transducer.
9 Chapter 2: Maintenance and Fault Finding Action Low battery Recharge your vessel’s battery as soon as possible DEPTH D4735-2 Display blank Action Check fuse/circuit breaker. Check power supply. ST40 DEPTH D4736-2 Depth reading flashes when under way Check SeaTalk cabling and connector security. Action Ensure that reading stabilises when clear of disturbed water, e.g. boat wakes, propeller wash etc.
10 ST40 Depth Instrument Owner’s Handbook SeaTalk information not being transferred between instruments For example, backlighting level changes implemented at one instrument do not affect other instruments Action Check security of SeaTalk connections between instruments. Check condition of SeaTalk cables. Isolate faulty instrument by disconnecting instruments one by one.
11 Chapter 3: Installation Chapter 3: Installation This chapter describes how to install the ST40 Depth instrument, and associated Depth transducer. The transducer is fitted in the hull of the vessel and is connected to the rear of the instrument. 3.1 Planning your installation Determine the best positions for both transducer and instrument, such that the EMC installation guidelines and the Site requirements (below) are satisfied.
12 ST40 Depth Instrument Owner’s Handbook • The equipment is supplied from a different battery from that used for engine start. Voltage drops below 10 V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. • Raymarine specified cables are used at all times.

14 ST40 Depth Instrument Owner’s Handbook The transducer should be sited within the clear water flow areas indicated by the shaded areas in the following illustration. Sailing vessel Planing power vessel Displacement power vessel Transducer siting D4349-1 The transducer should also: • Be ahead of the propellers (by a minimum of 10% of the water line length ). • Be at least 150 mm (6 in) away from the keel (ideally ahead of the keel if a sailing yacht).

16 ST40 Depth Instrument Owner’s Handbook 3.2 Procedures Adapt these procedures as appropriate, to suit your individual requirement. CAUTION: Where it is necessary to cut holes (e.g. for cable routing and instrument mounting), ensure that these will not cause a hazard by weakening critical parts of the vessel’s structure. If in doubt, seek advice from a reputable boat builder. Fitting transducer Instructions for installing and maintaining the depth transducer are packed with it.
17 Chapter 3: Installation Connections to the instrument You can connect your instrument: • Directly to the depth transducer as a stand-alone master instrument. When connected in this manner, the instrument must be connected to a suitable power source using the 1 m (3 ft) power cable provided. • As part of a SeaTalk system either as a repeater or, with a transducer also connected as a system master. To connect to SeaTalk, you will need an additional SeaTalk Interconnection Kit (Part No. E25028).
18 ST40 Depth Instrument Owner’s Handbook Stand-alone connections CAUTION Ensure that the power supply for each stand-alone ST40 instrument is protected by a 3 A fuse or circuit breaker. 3 A circuit breaker Red +ve Note: A 3 A fuse can be used in place of the circuit breaker, if preferred.

22 ST40 Depth Instrument Owner’s Handbook D4646-1 To bracket mount your ST40 instrument, do so in accordance with the Instruction Sheet, which is included with the Desktop Mounting Bracket. 3.3 Calibration requirement Once installation is complete and before you use your instrument, carry out the calibration procedures detailed in Chapter 4, Calibration. 158_2c03.
23 Chapter 4: Calibration Chapter 4: Calibration 4.1 Introduction The procedures in this Chapter must be carried out before the equipment is used operationally, to optimise the performance of the instrument with the vessel. Calibration information is presented in flow chart form. The flow charts show the various calibration screens and key presses necessary to carry out calibration. All key presses are momentary unless otherwise stated.
24 ST40 Depth Instrument Owner’s Handbook Depth offsets WARNING: The use of incorrect offset values could result in misleading depth information being displayed with a consequent risk of running aground. The depth offset screen enables you to determine the exact point on the vessel from which depths are measured. This point can be: • The transducer. Set offset to zero. With zero offset applied, the screen header is OFST. • The bottom of the keel.
25 Chapter 4: Calibration USER CALIBRATION During normal operation hold down and for approximately 2 seconds Entry screen Note: If there is no key activity when the Entry screen is displayed, calibration will time out to normal operation after 5 seconds, Depth response 15 (fast) CAL Depth units 1 (slow) CAL FA Shallow alarm lock CAL M Depth offset CAL WARNING: Correct offset values are essential to ensure the safe operation of the vessel.
26 ST40 Depth Instrument Owner’s Handbook 4.3 Intermediate calibration Intermediate calibration enables you to: • Check the instrument software version. • Set the instrument status - either MASTR (master) or REPTR (repeater). Follow the procedure in the Intermediate calibration flow diagram.
27 Chapter 4: Calibration DEALER CALIBRATION During normal operation hold down and for approximately 12 seconds Entry screen Note: If there is no key activity when the Entry screen is displayed, calibration will time out to normal operation after 5 seconds, Calibration access CAL If Return to normal operation with factory defaults set If Factory defaults Boat show mode CAL CAL CAUTION: Do NOT switch the Boat Show mode on. This function must only be used for demonstration purposes.
