Output Contactor
Feedback
C,S
Occurs when feedback from an output
contactor does not follow the command
to the coil of that conactor.
Either the output contactor is supposed
to be open and the feedback dictates
that it is cosed, or the output contactor
is supposed to be closed, and the
feedback indicates that it is open..
When there is an output contactor, it is
intended to be controlled by a digital output
programmed as “Output Contactor Control”
and to have its normally open auxiliary
contact monitored by a digital input
programmed as “Output Contactor
Feedback”. Determine if the auxiliary contact
has malfunctioned.
Verify that 120VAC is being supplied to the
auxiliary contactor.
Verify that no other inputs are programmed
as “Output Contactor Feedback”.
717 DC Link Reactor C,S
Occurs when one of the digital
inputs…is programmed as “DC Link
Reactor Fault”, and 120VAC is
removed from that digital input on the
remote I/O.
When there is a DC Link reactor, it is
intended to monitor its failsafe (normally
closed) protective devices (temperature or air
flow switches) with a digital input
programmed as “DC Link Reactor Fault”.
Verify that 120VAC is being supplied to the
switches.
Verify that no other inputs are programmed
as “DC Link Reactor Fault”.
718 Output Reactor D
Occurs when one of the digital
inputs…is programmed as “Output
Reactor Fault”, and 120VAC is
removed from that digital input on the
remote I/O.
When there is a Output reactor, it is intended
to monitor its failsafe (normally closed)
protective devices (temperature or air flow
switches) with a digital input programmed as
“Output Reactor Fault”.
Verify that 120VAC is being supplied to the
switches.
Verify that no other inputs are programmed
as “Output Reactor Fault”.

CCI IO Coomunication
Loss
C,S
Occurs when communication between
the Computer Card and the Remote IO
in the Customer Control Interface
enclosure stops for more than two
seconds.
Verify that all network cables inside the
Customer Control Interface enclosure inside
the low voltage section of the inverter and
between the two sections, are installed
properly and that all network routers are
powered.
