Test
Measure the input voltage to
the robot signal exchange
proxy.
Tip
For more details, see Circuit
diagram - OmniCore C90XT.
Confirm that the controller is
for CRB 15000 or not.
Check connection to the
power supply unit.
Measure the 24 V DC outputs
voltage.
Check the indicator LEDs
AS1, AS2, ES1, ES2.
Check that the customer inter-
face connectors are well con-
nected to X14 and X15.
Tip
For more details, see Circuit
diagram - OmniCore C90XT.
Check external safety ac-
cessories.
Measure the AC OK signal.

Action
Use a multimeter and insulating gloves.
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 5.
• If the input voltage is abnormal, proceed with
step 3.
• If the controller is for CRB 15000, see
Troubleshooting the power unit on page
• If the controller is not for CRB 15000, proceed
with step 4.
• If the connection is OK,
power supply on page
• If there is a problem with the connection, re-
pair the connection and start over.
Use a multimeter and insulating gloves.
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 6.
• If the output voltage is abnormal, proceed with
step 10.
The indicator LEDs are labelled AS1, AS2, ES1, ES2.
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 7.
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 8.
• If there is a problem with the connection, re-
pair the connection and go to step 6.
Use a multimeter and insulating gloves.
Measure the continuity in the connector. If there is
resistance, troubleshoot the external equipment.
Use a multimeter and insulating gloves.
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
• If the AC OK signal is 0 V, proceed with step
10.
