Check fuses F1/F2

Change PCB
6.5 MALFUNCTION OF THE D93/D94
• Check that the ±10V is present at the input terminals TB4-3/4
(Interconnection PCB)
•
If not, check that the 10kHz feedback signal is present by
measuring the frequency at TB2-1/2 (Interconnection PCB).
Eventually check that the Thruster switch closes J4-11 to 13.
•
Disconnect the analogue signal from dual analogue PCB (TB20, 1-2
and TB21, 1-2. If ±10V is normal, the analogue amplifier(s) must be
checked.
•
If no output, change PCB.
6.6 THRUSTER INTERFACE PCB
Check as for D93. Output signal is checked on TB9, 1-2.
