  • Page 162 Maintenance Instructions 2 - 3 2.3 CORRECTIVE MAINTENANCE 2.3.1 Troubleshooting 2.3.1.1 Overcurrent situation A selected output channel of your power supply can be in overcurrent for one of the following reasons: • The programmed (maximum) current level is lower than the actual load current and the OverCurrent Protection (OCP) circuitry has been enabled.
  • Page 163 2 - 4 Reference Manual • Another output channel is in overvoltage, and protection coupling has been enabled. Solution: Remove the cause of the OVP in the coupled output channel and reset the coupled output channel by pressing the RESET key. If allowed, remove the coupling of the OVP mechanisms of the output channel(s) involved.
