My new N2K
network is now more or less fully operational. Just waiting for the other Zeus to be delivered so I can do the binnacle, but I've got the cable pulled to the scuttle and 3 Tritons installed and working there, and have all the
engine room
equipment installed and connected. Hurrah!
One problem I've had, however, is that the Zeus at my nav table won't connect to the
network except through a Simnet joiner. You are supposed to connect it directly using a Simnet-to-N2K pigtail, according to the instructions, but it doesn't
work that way.
The other problem I've had is that I have been unable to commission the
autopilot. I get through the
rudder feedback calibration ok, but when I try to perform the
rudder test, I get an error "AP
clutch overload".
The
documentation says this means that the
clutch (actually, a bypass valve) is drawing more than 3.3 amps or is shorted. But I measured the
current draw -- only 2 amps -- and not shorted -- voltage normal.
Navico tech support tell me, despite what the
documentation says, this means the AC42N computer can't handle the
current of the
Raymarine bypass valve (I have a
Raymarine Type III reversing hydraulic
pump and large hydraulic ram mounted to the quadrant, which is supposed to be compatible with the
Simrad pilot computer). They have instructed me to install a relay.
Well, that's annoying. The pilot computer was supposed to be compatible, and there is no obvious violation of the specs. It's not so hard to wire up a relay but still annoying.
Anyone else experience this problem?
