Gateway Status Leds - Carrier 19XRV Start-Up, Operation And Maintenance Instructions Manual

release the force on SERVICE ONTIME after the desired
value has been set.
9. Perform the guide vane calibration procedure (in Control
Test). Check and recalibrate pressure transducer readings
(refer to page 68). Check that the CURRENT TIME and
DATE in the TIME AND DATE screen are correct.
DPI Communications Interface Board Status LEDs — VFD
status can be determined from the status LEDs on the DPI
Communications Interface Board shown in Fig. 46. The DPI
Board is mounted on the front of the VFD power module in a
vertical orientation.
Gateway Status LEDs —
provides a communication link between the CCM and ICVC
SIO bus to the VFD Drive Peripheral Interface (DPI) board.
The SIO bus communicates with the Gateway through VFD
connector A32. See Fig. 47.
The Gateway has four status indicators on the top side of the
module.

Drive ready, but not running and no faults are present.
Drive running, no faults are present.
The drive is not ready. A VFD start inhibit is in effect. Normal condition when chiller not running because the ICVC has issued a stop command.
An alarm condition exits. Check VFD FAULT CODE in ICVC VFD_STAT screen.
A fault has occurred. Check VFD FAULT CODE in ICVC VFD_STAT screen.
A non-resettable fault has occurred. Check VFD FAULT CODE in ICVC VFD_STAT screen.
VFD Gate Kill circuit has opened because the compressor high pressure switch has opened.
RECTIFIER STATUS LIGHT
Rectifier ready, but not running and no faults are present.
Rectifier running, no faults are present.
Rectifier is not ready. A VFD start inhibit is in effect. This is a normal state if the inverter is not running and/or the precharge contacts are open.
Rectifier alarm condition exits. Check VFD FAULT CODE in ICVC VFD_STAT screen.
Rectifier fault has occurred. Check (VFD FAULT CODE in ICVC VFD_STAT screen.
A non-resettable fault has occurred. Check VFD FAULT CODE in ICVC VFD_STAT screen.
VFD Gate Kill circuit has opened because the compressor high pressure switch has opened.
Control board application firmware may be corrupt. Call Carrier Service.
Control board RAM failure or control board firmware may be corrupt. Call Carrier Service.
