ST 60 Wind Transducer Tests & Alignment
PIN WIRE FUNCTION
1 BLACK 0V – SHIELD
2 RED + 8VDC SUPPLY
3 GREEN + 2-6 VDC STB DIRECTIONAL ELEMENT
4 BLUE + 2-6 VDC PORT DIRECTIONAL ELEMENT
5 YELLOW + 0-5 VDC SPEED
Looking into Masthead transducer arm plug
Red to shield should read 8 volts DC steady.
This is the masthead power supply, coming
from the ST50/ST60 display head. If the
head is damaged, you may need to provide
this power from another source to test the
Blue to Shield should read anywhere
between 2 and 6 volts DC. This is the port
side directional element. The voltage
changes as the vane turns.
Green to Shield should read anywhere
between 2 and 6 volts DC. This is the
starboard side directional element.
Yellow to shield should read between 0 and
5 volts DC. This is the wind speed circuit.
The faster the wind is blowing, the higher
the voltage will read.
If any of these readings are out of spec, you
should assume the masthead is damaged, and it should be repaired or replaced.
Raymarine has a repair shop you can ship these transducers to for repair. I believe it is about $145.00 to
rebuild the unit. Go to their web site for more info. If you have an authorized dealer nearby, you can
take it to him.
Basically if all is working in accordance with the above, then align the transducer so that the maximum
voltage, on PIN 4, is achieved with the vane pointing to Starboard.
