Verify less than zero (0) vdc voltage at VFD connections shown on
cover.
Table 2 – VFD LED Indicator Functions
LED Identification Color Function
R1 Red
Used to indicate that high voltage is present in the DC capacitors. If this LED is lit then a DC voltage greater than 40V
is present.
G1 Green Blinks when the VFD receives a message from PCM.
G2 Green On when VFD is in normal status. It is off when VFD is fault status.
G3 Green On when the VFD microcontroller relay is closed. The signal of relay is controlled by PCM.
A1 Amber On when 12V source is normal.
A2 Amber On when the main relay is closed.
