Connect a jumper wire (a paper clip will suffice) between
terminals #4 and #5. The instrument should indicate “0”
wind speed and “WSW” direction. If it does then continue
to step 4. If not, continue to step 3.
Connect the same jumper wire used in
step 2 to between terminals #3 and #4.
The instrument should now indicate “0”
wind speed and “WSW” direction. If it
does then continue to step 4. If not, the
fault is in the instrument.
Remove the sensor from the roof and
connect it to the indicator with short
pieces of wire.
Rotate the vane slowly and observe the
lights. If it still does not operate properly,
then the fault is in the sensor. Otherwise
the fault is in the installed wire.
The unit will no m the self test, all LEDS will light f w perfor or about 3 seconds. If y e time ou do not hav
to check that all LEDS light, repeat the procedure. This will cause the self test to start again. If some
or all of the LEDS do not light, then the fault is in the instrument.
