Functional Test (Z080 Masthead Transducer); Functional Test (Z087 Pushpit Transducer) - Raymarine ST6000 Service Manual

1. Description
The Z080 and Z087 Windvane transducers are only compatible with Autohelm
Seatalk products. The push pit transducer (2087) is identical to the Vane transducer
in the Masthead Unit (Z080). When connecting a masthead Transducer (Z080) to an
Autohelm ST7000 Autopilot do not connect the yellow core into the Aux 1 connector
in the connector box. Simply connect the other four cores and trim the yellow back
short.

2. Functional Test (Z080 Masthead Transducer)

The operation of the Z080 masthead mounted windvane can be checked using the
following procedure:-
1. Connect +8V dc to the red core and 0V to the screen.
2. Connect a digital volt meter across the screen and the green core.
3. Rotate vane head through 360 degrees and check that the meter reading oscillates
sinusoidally. The maximum reading must be between 6V and 5.5V. The minimum
reading must be between 2V and 2.5V.
4. Repeat section 3 with the meter connected across the blue core and screen.
The anemometer transducer can not easily be tested and a replacement pod should
be fitted if suspected faulty.

3. Functional Test (Z087 Pushpit transducer)

The pushpit vane transducer can be functionally checked by following the Masthead
test procedure.
