PRESSOR ON TIME are both incorrect, the ICVC soft-
ware must be downloaded again before these settings can
be changed.
9. Check and recalibrate pressure transducer readings (refer
to page 95). 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. 62. The DPI
Board is mounted on the front of the VFD power module in a
vertical orientation.
Gateway Status LEDs — The RS485 VFD Gateway
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. 63.
The Gateway has four status indicators on the top side of the
module.
DRIVE STATUS INDICATOR — The DRIVE status indi-
cator is on the right side of the Gateway. See Table 23.
Table 23 — Gateway DRIVE Status Indicator
MS STATUS INDICATOR — The MS status indicator is the
second LED from the right of the Gateway. See Table 24.
Table 24 — Gateway MS Status Indicator
NET A STATUS INDICATOR — The NET A status indica-
tor is the third LED from the right of the Gateway. See
Table 25.
Table 25 — Gateway NET A Status Indicator
NET B STATUS INDICATOR — The NET B status indica-
tor is the left LED on the Gateway. See Table 26.

STATE CAUSE CORRECTIVE ACTION
OFF The Gateway is not
powered or is not con-
nected properly to the
drive.
• Securely connect the
Gateway to the drive
using the DPI ribbon
cable.
• Apply power to the drive.
FLASHING
RED
The Gateway is not
receiving a ping mes-
sage from the drive.
• Verify that cables are
securely connected.
• Cycle power to the drive.
SOLID
RED
The drive has refused
an I/O connection from
the Gateway.
IMPORTANT: Cycle power
after making the following
correction:
• Verify that all DPI cables
on the drive are securely
connected and not dam-
aged. Replace cables if
necessary.
ORANGE The Gateway is con-
nected to a product
that does not support
Rockwell Automation
DPI communications.
• Check wires leading to
the A32 terminal block.
• Check that A32 terminal
block is fully engaged.

Recoverable Fault
Condition
Cycle power to the drive. If
cycling power does not cor-
rect the problem, the firm-
ware may need to be flashed
into the module.
SOLID
RED
