5. Check voltage at power module output to transformer (220–240
VAC)
Check voltage on plug CP2B on power module.

see Point 6
6. Check voltage at power module input from transformer
The secondary voltages (15 VDC / 9 VDC) of the transformer are
measured on the flat plug CP4 (2 x red = 15 VDC / 2 x white = 9 VDC)

7. Check voltage at power module output to logic (5 VDC)
The output voltage is measured from the power module to the logic
module (control electronics) on plug CP9, terminals 1 = GND (brown)
and 2 = + 5V (red).

8. Check voltage on logic module input
Measure voltage input on plug CM9 of the logic module on terminals 1
= GND (brown) and 2 = + 5 V (red).
