NEXUS Autopilot 1510 summary of known checkpoints

All Autopilot systems are complex systems dependant of a number of
transducers and control algorithms why faultfinding needs to be done
carefully to lead to correct remedy.

Checkpoints:
Power:
It is essential to Power the Pilot servo and the Pump motor to get
current enough without risk of voltages drops.
Wireing can be effective by using Relay to get shorter length of
cables.

Autopilot Servo: The PCB, circuit board shall have an extra grounding acc. to Service Bulletin 00-23. Can be seen as two extra wires on the PCB. Software and settings: Check that AP Servo S/W is of latest version 3.6 Marked with a sticker on the EPROM. Check dip switches: Keep in Down Up= Solenoid position Down= Pumpset 12 V 24 V Note! With all Silva Pumpsets both dip-switch shall be in down position. Rudder angle Transmitter RAT/RFU: The Rudder angle Transmitter must

If a linear Rudder angle transmitter is used there should be two end- resistors, one on Black and one on Red wire from the RAT/RFU according to separate instruction, see Silva support: Autopilot Installation of the Linear rudder angle transmitter. Hydraulics: Check for Air in the system and bleed if needed (not valid for Silva HP 40 pumpset). Compass transducer: If the system has a Nexus Server, connect the Compass transducer to the Server for optimal function. Auto-deviation: Co
