Corrections
— Tighten loose screws.
Reconnect grounding cable.
Repair or replace the faulty item.
Replace faulty power supply.
Possible cause check-up and tests
— Check with the positive probe of the
multitester the voltage at different
grounding points of the autoclave, on
the ANL-T2 and DIG-T2 boards, on
the enclosure of the electric box and
the main grounding screw of the
machine.
The voltage differences must be less
than 5mV.
Higher voltage may indicate that ANL-
T2 board fastening screws are loose or that
the power supply cable is loose.
1.6.2 Check the 12VDC voltage.
— Connect the negative probe of the
multitester to TP1 (GND).
— Connect the positive probe of the
multitester to TP3. The indication of
the instrument must be 10.8-12.5V.
If indication is not as specified,
disconnect the output connector of the
power supply. If the right value is
achieved ther is a short circuit.
Identify and locate the short circuit.
If instrument indication is below or
above specified range the power
supply is faulty.
1.6.3 If neither 12V nor 5V voltages are output:
— Check the voltage transfer to the power
supply through the connector JP2
on the AC - T1 board.
