"Fault no.: 140" (mains power supply)
Possible cause:
No mains power supply to power module
Remedy:
1. Check the power supply cable for continuity and
replace if necessary.
DANGER - Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.
2. Check voltage at measuring points X4 and X2
directly behind the power inlet socket connector on
the power supply module (see sec. 5.6).
 Voltage must be 230 V.
 If the voltage differs or is not present, the pow-
er inlet socket connector or the connecting ca-
bles from the power inlet socket connector to the
