startup hardware test.
What to do:
Check if +24V_PTC is available at P59 on PC 1675 Power Supply:
• If +24V_PTC is not available, replace the AC/DC Converter.
Note: As the two fans inside the battery drawer runs on +24 V, this error is easy to
identify by checking the function of these fans.
• If +24V_PTC is available, this voltage is correctly generated by the Power Supply
system. The error must be found in the cables/connectors or on PC 1672 Control
Panel.
