Check and recalibrate pressure transducer readings(refer to page 68). Check that the CURRENT TIME andDATE in the TIME AND DATE screen are correct.DPI Communications Interface Board Status LEDs — VFDstatus can be determined from the status LEDs on the DPICommunications Interface Board shown in Fig. 46. The DPIBoard is mounted on the front of the VFD power module in avertical orientation.Gateway Status LEDs — The RS485 VFD Gatewayprovides a communication link between the CCM and ICVCSIO bus to the VFD Drive Peripheral Interface (DPI) board.The SIO bus communicates with the Gateway through VFDconnector A32. See Fig. 47.The Gateway has four status indicators on the top side of themodule.RECTIFIER LED INVERTER LEDDPI COMMUNICATIONS INTERFACE BOARDINVERTER STATUS LIGHTRECTIFIER STATUS LIGHTINVERTER AND RECTIFIER CONTROL BOARD FAILURE STATUS LIGHT PATTERNSFig. 46 — DPI Communications Interface Board Status LEDsCOLOR STATE DESCRIPTIONGreen Flashing Drive ready, but not running and no faults are present.Steady Drive running, no faults are present.Yellow Flashing The drive is not ready.
