8.2.2 Checking the languages loaded in high memory
If there are no languages loaded, the following messages are dis-
played:
No Language loaded. Restart in PC Mode.
Use the AU2019 prog. to load them
See § 9.2.5 to load the language file.
8.2.3 Checking supply voltages
If a fault is detected during the power supply check, the message
“PS Test Error, code X “ is displayed and the program loops endlessly
through a sequence with LED D12 on for 0.5 s and off for 1 s.
Each bit of the binary equivalent of the displayed 5-bit code X gives
the state of one of the verified voltages: 0 if the voltage is correct,
otherwise 1.
X is a number between 1 and 31. Example: “PS Test Error, code 3”
indicates an error at the first two measured voltages (–5 V and +5 V).
Bit
Ux
Bit set to 0 if the measured voltage Ux is
1
–5 V
–5.3 V < Ux < –4.7 V
2
+5 V
4.7 V < Ux < 5.3 V
3
+3 V
2.85 V < Ux < 3.15 V
4
+6.5 V
6.29 V < Ux < 6.68 V
5
+7.5 V
7.30 V < Ux < 7.60 V
