Inverter blink codes

All Fischer Panda PMGi inverters have status LEDs. But what do the blink codes actually mean? This article explains the blink codes of the inverter LEDs. Let’s dive into this topic.

Meanings of the graphics
LED is switched OFF permanent
LED is flashing
LED is switched ON permanent

Status LEDs in normal operation

Pre-glow

During the pre-glow the red LED lights permanent. The green LED remains off.

Override mode

Note: There are different blink codes in override mode for older and current inverters.

PMGi with the P12000 control board: During the override mode the red and the green LED are flashing alternately.

Current PMGi with the FP1503 control board: During the override mode the red LED lights permanent while the green LED is flashing.

Operating mode

In operating mode the green LED lights permanent. The red LED remains off.

Two Inverters in parallel mode

If two inverters are operated in parallel, the green LED shows which of the two inverters is operated as master and which is operated as slave.

Master: The green LED lights permanent. The red LED remains off.

Slave: The green LED flashes permanent. The red LED remains off.

MANDATORY INSTRUCTION: Observe the instructions in the manual
General warning
WARNING: General warning
Event description
  • After starting sequence the red LED lights permanently.
Possible causes of this event
  • Error inside the inverter.
  • Communication cable is connected incorrectly.
  • No communication with the generator.

Event description
  • After running in operating mode the red LED lights permanent.
  • The inverter no longer supplies an output voltage.
  • The control panel doesn’t display any error message.
Cause of this event
  • Disturbance of the inverter supply voltage.

Event description
  • After starting sequence the green LED flashes permanent.
Cause of this event
  • The soft start is activated until the inverter reaches its 220 V output voltage.

Event description
  • After starting sequence the red LED flashes permanent.
Cause of this event
  • The Inverter software does not support the selected generator type. This might be occur if an older inverter is operated on a current generator.

Event description
  • The generator stopped with an error.
  • The Message »Inverter overload« is displayed on the iControl2 panel.
  • The red LED lights permanent.
Possible causes of this event
  • The Inverter has been overloaded.
  • Short circuit is located inside the inverter.
  • Short circuit at the output.
  • Defective winding.

Event description
  • The generator stopped with an error.
  • The message »Inverter overtemp« is displayed on the iControl2 panel.
  • The red LED lights permanent.
Cause of this event
  • The maximum permissible operating temperature of the inverter has been exceeded.

Event description
  • In operating mode: Although no output voltage is present at the terminals the green LED lights permanent.
Cause of this event
  • The single-line filter is faulty or the cables are not right connected to the terminals of the filter.

Meaning of the status LEDs of multi-phase inverters

  • The red LED is lighting: »Power On« (12 V supply voltage of the inverter is OK).
  • The green LEDs are lighting: »Output voltage OK« on all phases, there is one green LED for each line (L1, L2 and L3 if available).
  • If one or more of the green LEDs do not light up, the output voltage of the corresponding phase is not OK.
  • If there is a failure on at least one phase the inverter shuts down.
