What is the PCS-FPGA-12 error on Felicity?

PCS-FPGA-12 on a Felicity unit means: FPGA hardware fault - phase B IGBT failure.. It can appear on 1 device in the Felicity catalog. The cause and recommended fix are listed for each device on this page.

Can I clear the PCS-FPGA-12 code myself?

It depends on the severity. Warning-level codes can usually be cleared by following the recommended fix. Fault and critical codes often require checking the source condition first; if the code returns immediately after restart, escalate to authorized service.

Is the PCS-FPGA-12 fix the same on every device?

The cause is consistent — it's the same protection logic. The exact fix wording can differ per device because each official manual addresses model-specific context (input ranges, parallel-config notes, firmware revisions). Use the per-device section that matches your unit.

Where does this information come from?

Every entry is sourced directly from the official Felicity user manual for the affected device. The "Source" line at the bottom of each device's section shows the manual filename and page number.

What does the PCS-FPGA-12 error code mean?

PCS-FPGA-12 on a Felicity unit indicates: FPGA hardware fault - phase B IGBT failure.. It is a fault-severity event that can appear on 1 device in the Felicity catalog. The same code may have slightly different recommended fixes depending on the device — the per-device sections below show the exact wording from each device's official manual.

This is a fault-severity code

Fault codes stop normal operation but the unit may attempt to recover. Common causes are out-of-range conditions (voltage, current, temperature) that require checking inputs and outputs before restart.

What triggers this code

PCS-FPGA-12 is triggered when the unit's protection or monitoring logic detects the specific condition described above. The exact trigger depends on the device — see the per-device sections for the official manual entry for each.
