Test
Check the indicator LED MS.
Measure the input voltage to
the robot signal exchange
proxy.
Tip
For more details, see Circuit
diagram - OmniCore C30,
Circuit diagram - OmniCore
C30 for IRB 14050, Circuit
diagram - OmniCore C30 for
CRB 15000.
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 connec-
ted to X14 and X15.

Action
If the LED_MS is:
• Green, proceed with step 6.
• Flashing red/green, a firmware upgrade error
has occurred. This is not supposed to happen
during runtime mode, proceed with step 11.
• OFF, either the robot signal exchange proxy
is faulty or it does not have sufficient input
voltage. Proceed with step 3.
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 6.
• If the input voltage is abnormal, proceed with
step 4.
• 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 5.
• 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 7.
• If the output voltage is abnormal, proceed with
step 11.
The indicator LEDs are labelled AS1, AS2, ES1, ES2.
If the LEDs LED_AS1, AS2, ES1, ES2 are:
• On (solid green), 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 8.
If the customer interface connectors are not properly
connected to X14 and X15, the signals to and from
the robot signal exchange proxy will be interpreted
incorrectly.
• If the connection is OK, proceed with step 9.
• If there is a problem with the connection, re-
pair the connection and go to step 7.
