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.<\/p>\n\n\n\n

Meanings of the graphics<\/h5>\n\n\n\n
\"\"<\/td>LED<\/strong> is switched OFF<\/strong> permanent<\/td><\/tr>

Status LEDs in normal operation<\/h3>\n\n\n\n

Pre-glow<\/h5>\n\n\n\n

During the pre-glow the red LED lights permanent. The green LED remains off.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n
Override mode<\/h5>\n\n\n\n

Note:<\/strong> There are different blink codes in override mode for older and current inverters.<\/p>\n\n\n\n

PMGi with the P12000<\/a> control board:<\/strong> During the override mode the red and the green LED are flashing alternately.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Current PMGi with the FP1503<\/a> control board:<\/strong> During the override mode the red LED lights permanent while the green LED is flashing.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n
Operating mode<\/h5>\n\n\n\n

In operating mode the green LED lights permanent. The red LED remains off.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n
Two Inverters in parallel mode<\/h5>\n\n\n\n

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.<\/p>\n\n\n\n

Master:<\/strong> The green LED lights permanent. The red LED remains off.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Slave:<\/strong> The green LED flashes permanent. The red LED remains off.<\/p>\n\n\n\n
