Drilltio 4mm(5/32in) clearance holes for the fixing studs (2) through the bulkhead. Cut the clearance hole for the cable boss (1) using a 50mm (2ir-r) diameter cutter. Pass the SeaTalk cable and transducer tails through the cableboss (1) clearance hole. Assemble the control head to the bulkhead and secure from behind using the thumb nuts (3). NO@. ?: Because the instrument breathes through the vent in the rear case, this bracket is for interior use only. Flush Mounting A flush mounting kii is available for installations where a flush mount is required or more desirable. Full installation instructions are provided with the kit. 3 Power Supply (stand-alone operation) 1. 5 Connection of Separated lnstnments Separated instruments can be connected using one of the range of SeaTalk Extension Cable. These cables are supplied with a SeaTalk connector fitted to each end. A junction box can be used to join the cable if it is cut for easier routing or shortening. if preferred, any 2 core, screened cable conforming the following specification may be used instead of the SeaTalk cable. l 22 AWG, 2 core screened cable with a minimum copper area of 0. 5mm2. 5 Amp circuit breaker 12v supply 1 . Cut the cable to length and connect the red wire totbe +12V terminal and screen to the OV terminal. Note: Longer runs to the power supply can be made using the 9m (3Oftl SeaTalk Extension Cable (D131). II I I 11 Junction box I\ 1 ' r Yellow 1 `-1 Screen-J L Red -I Ucreen I 1 I . Power Supply (SeaTalk qperation) All instruments in a SeaTalk system receive power and information from the SeaTalk bus. Each instrument has two SeaTalk connectors (3 pin) on 15Omm (6in) tails. To supply power and information to the instrument simply plug the adjacent instrument tails into the ST50 Plus tails.

Whether a second ring main is required can be determined from the following: 2. 1 Connection to the Control Head The ST50 Plus Wind is supplied with a transducer cable tail and connector which simply plugs into the 30m f10Ofbiransducer cable. Cable run upto 1Orn (33ft) Single connection: Secofd connection: Single connection: Second connection: 13 instruments maximum 26 instruments maximum 7 instruments maximum 13 instruments maximum 2. 2 Masthead Transducer Installation Cable runupto 20m (66ft) n The second ringmain should be connected to the spare lead on the last instrument in the chain and directed back to the circuit breaker. Connection to SeaTalk Compaljble Autopilots lf the installation includes a SeaTalk compatible Autopilot fhe ST50 instru ments may be connected to the SeaTalk bus at any point. No independent connection to the 12V power supply is necessary as the instruments receive power from the Autopilot course computer. For best performance the mounting block must be fixed to a horizontal surface. lfthe mast top is not horizontal, make up a wedged packing piece (1).

Secure the mounting block to the mast top using the two screws (4). Chapter 3: Fault Finding and Maintenance 3. 1 Fault Finding All Autohelm products are, prior to packing and shipping, subjected to comprehensive test and quality assurance programmes. However, if a fault arises with the ST50 Plus Wind, the following table will help to identify the probable cause and provide the most likely cure. Fault Cause Action 5. Cut the cable so that there is sufficient length to run from the masthead iransducer to the below deck junction box. Feed the cable down the mast -if the mast is deck stepped the cable should be passed through the deck using a proprietary deck gland. [. . . ] Once selected a solid marker appears above the selection. Chapter 5: CODE Lock Security 5. 1 Secubty Code The ST50 Plus range of instruments is equipped with a security code feature (called `CODE Lock') to protect your system against possible theft. Entered using the keypad on digital instruments, this is a four figure number of your choice that can be entered at every power-up or, alternatively, transmitted automatically on the SeaTalk bus when there is a secure belowdecks master instrument. The analogue ST50 Plus Wind will only respond to transmissions on the SeaTalk bus -a security code cannot be entered from this unit. Press < > for 1 second to move the pointer by 10 degrees/second.
