[TG] [TG11] Evo1, P70 ‘No Pilot’ and SOG

[Cabron]

Just installed a Evo1 Wheel kit on a 35 foot Mono/Sail, included a rudder reference, Used a converter from ST-STNG from a set of ST50’s.

Installed with no issues, all ST50 data besides:
1) SOG doesn’t appears on P70 display, though when sailing, AWS on P70 seems to calculate SOG and True Wind, So seems it’s using SOG data, but not displaying it
2) Wind vane while correct as ST50, sometimes can be 180 degrees out on the P70 mainly in lighter wind...if vane isn’t moving, reading should be the same no?

Other problem, when Harbour/river motoring it calibrated well, and holds course beside in vane mode as direction is incorrect(Autotack in vane mode does 360degrees before I stop it) but under sail the P70 faults out ‘No Pilot’, motor is warm but not hot, and light winds, and small following sea.

Changed from Slow Sail to Sail, and from Cruising to Leisure mode. Still faulted after 5-10minutes saying No Pilot. Motor just stops locks a rudder angle.

When motor/sailing, didn’t seem to fault again?

Any help would be great

Thanks

Hello [censored],

Could you expand on exactly what you're seeing, please? AWS does not use SOG: True Wind (TWA, TWS) are calculated from AWA/AWS and speed-through-water (paddle-wheel Speed.) See http://forum.raymarine.com/showthread.php?tid=987 for details.

Please can you confirm exactly what data item you're looking at on the p70, and whether you're looking at True or Apparent wind on the ST50? The usual reasons for a mismatch in displayed wind data are:

1. Looking at different wind data types (True, Apparent or Ground wind) on the different displays
2. Analogue instrument pointer calibration (different digital data output onto Seatalk to what's being indicated by the pointer)

A 'No Pilot' alarm means a loss of STNG / NMEA2000 communication between the pilot display and the EV autopilot sensor core (which contains all of the pilot intelligence.) If that only happens when sailing then I think that the most likely cause is a voltage drop on that segment of the STNG network, perhaps due to a loose or corroded connector.
