6 TROUBLE SHOOTING
An autopilot is a complex system and the performance is dependent of a
proper installation and a successful sea trial.
In the event of a failure, you will be helped by the AP35 software which
contains several test features that will assist you in isolating a probable fault.
Audible and visual alarms are given in the event a fault is detected.
The audible alarm is reset by pressing any button (e.g. by changing mode
from AUTO to STBY). The visual alarm will remain and alternate with the
operating display until the fault has been rectified. Refer to the table below
for hints and try to solve the problem yourself, or consult your nearest
Simrad dealer for assistance.
Perform the repair action in the listed order.
6.1 Alarms
Display readout
Probable fault Recommended action
System failure Alarms:
Rudder feedback
failure (autopilot
operates on simulated
feedback)
Rudder feedback signal
missing or erratic
1. Check all connections.
2. Check the alignment as per the
installation instructions
3. Replace rudder feedback unit.
Rudder response
failure
No response to rudder
command.
1. Check all connections
2. Check Rudder FB transm. link.
3. Check Drive unit motor/brushes.
4. Replace junction unit Power PCB.
Rudder test too slow Excessive load on steering
gear. Air in hydraulic
system. Insufficient drive
unit capacity.
1. Look for mechanical obstructions
at the rudder/tiller/quadrant.
Check the back drive force.
2. Bleed the hydraulic system.
3. Replace with bigger pump unit.
Rudder test failed Following conditions may
exist:
a) Rudder feedback failure
b) J3XX current overload
c) Bypass/clutch overload
Refer to recommended actions for the
specific probable faults.
Rudder moves in one
direction only
a) Poor connection to
one of the solenoids
(continuously running
pump)
b) Faulty Power PCB in
junction unit
a) Check connections
b) Replace PCB
