11.2.3 24V Power supply check
Warning
The switching power supply can have dangerous voltage.
Wait for at least 5 minutes before carrying out any action.
Before performing the following procedure, verify the main fuse integrity (see
paragraph 11.3.1.1) and the main power supply line (see paragraph 4.2.1 and
chapter 12 – General Diagram).
Verify if the MCU LED H1 is ON
1. If MCU H1 is OFF, remove the cable X1 and verify the 24V between X1-pin1 and
X1-pin2.
• IF X1 24V is NOT OK, fix or replace the cable X1 and then the switching
power supply G1.
• IF X1 24V is OK, unplug the connector X11 and verify if the MCU LED H1
light up:
▪ IF MCU H1 is still OFF, replace the MCU board A1
▪ IF MCU H1 is now ON, verify the integrity and the insulation between
pin1 and pin2 of cable X11-X37. If the problem is still present, replace
the 3D sensor power board.
2. If MCU H1 is ON, verify if the MCU LED H2 is ON.
Note
If the LED H1 is ON the 24V to the 3D sensor power board is correctly
supplied by the MCU connector X11. In this case, if there are still problems
related to the 3D sensor connection, check the cable X11-X37 and then
refer to Error E1402 (see paragraph 9.2.10.2).
a. IF MCU LED H2 is OFF, verify that fuse F1 is not blown:
• IF fuse F1 is blown, replace it and verify if the error is still present (* see
Note below).
• IF fuse F1 is NOT blown, disconnect the motors connectors (X18, X19,
X20 and X34) and verify if the LED H2 lights up:
▪ IF MCU H2 is still OFF, replace the MCU board A1
▪ IF MCU H2 is now ON, connect one at a time the motors connectors
and verify which ones are the origin of the problem. (* see Note
below).
