CIB_SR Microcontroller I/O Node Internal Fault

What does LED_STA1_CIB_FLASH mean?

The STA1 (CIB_SR) LED for the microcontroller I/O node on the KUKA KRC4 Sunrise Cabinet Med Controller is flashing, indicating an internal fault. This fault affects the I/O processing capabilities of the CIB_SR module, impacting robot control and sensor/actuator interaction.

• Internal malfunction within the CIB_SR microcontroller's I/O node.
• Insufficient or unstable power supply (e.g., related to fuse F17.3 or PWR/3.3V LED status).
• Component failure on the CIB_SR module.

Click steps to track your progress.

1. 1

   Check fuse F17.3 on the Cabinet Control Unit, Small Robot (CCU_SR) and replace if defective.

2. 2

   Observe the PWR/3.3V LED; if it lights up, but STA1 (CIB_SR) is flashing, the issue is likely internal to the CIB_SR microcontroller.

3. 3

   Perform a system power cycle for the KUKA KRC4 Sunrise Cabinet Med Controller to attempt a reset.

4. 4

   If the fault persists, prepare to exchange the CCU_SR module, which contains the CIB_SR module.
