Action Test
Use a multimeter and insulating gloves. Measure the input voltage to
the robot signal exchange
proxy.
Tip
For more details, see Circuit
diagram - OmniCore C90XT .
2
The input voltage should be 24 V.
Make sure that connector X1 is connected properly
on both ends.
• If the input voltage is normal, proceed with
step
4 .
• If the input voltage is abnormal, proceed with
step
3 .
• If the connection is OK, Troubleshooting the
power supply on page 401 .
• If there is a problem with the connection, re-
pair the connection and start over.
Check connection to the
power supply unit. 3
Use a multimeter and insulating gloves. Measure the 24 V DC outputs
voltage. 4
The output voltage should be 24 V.
Make sure that connectors X2, X3, X4, X5, X17 and
X19 are connected properly on both ends.
• If the output voltage is normal, proceed with
step
5 .
• If the output voltage is abnormal, proceed with
step
9 .
The indicator LEDs are labelled AS1, AS2, ES1, ES2. Check the indicator LEDs
AS1, AS2, ES1, ES2. 5
If the LEDs LED_AS1, AS2, ES1, ES2 are:
• On (solid yellow), the robot signal exchange
proxy works well.
• Off, either the robot signal exchange proxy is
faulty or it does not have sufficient input
voltage. Proceed with step
6 .
If the customer interface connectors are not well
connected to X14 and X15, the robot signal exchange
proxy cannot work normally.
• If the connection is OK, proceed with step 7 .
• If there is a problem with the connection, re-
pair the connection and go to step
5 .
Check that the customer inter-
face connectors are well con-
nected to X14 and X15.

Use a multimeter and insulating gloves. Check external safety ac-
cessories. 7
Measure the continuity in the connector. If there is
resistance, troubleshoot the external equipment.
Use a multimeter and insulating gloves. Measure the AC OK signal. 8
The AC OK should be 0 V.
Make sure that connector X10 is connected properly
on both ends.
• If the AC OK signal is 24 V, see
Troubleshooting the power unit on page 382 .
• If the AC OK signal is 0 V, proceed with step
9 .
How to replace the unit is detailed in Replacing the
robot signal exchange proxy on page 192 .
The robot signal exchange
proxy may be faulty, replace
it and verify that the fault has
been fixed. 9
