Faults
Table 3-4 lists all possible faults. Faults are conditions that indicate that the
charge controller might have incurred permanent damage or that user
intervention is required before the charge controller will operate again. If one of
these faults occur, the charge controller might also need to be serviced before it
can be fully operational again.
1.Additional steps are required for a ground fault. See “GroundFlt1” in Table 3-4.
Table 3-4 Fault messages
Display Text
(Description) Fault ID Definition
AuxPSFlt
(Auxiliary power
supply fault)
F54 More than two auxiliary power supply errors (F26) have occurred
within one minute.
Damage to the charge controller is possible, so the fault will not
clear until an operator clears it manually using the SCP.
GroundFlt1
(Ground fault,
type 1)
F56 A PV ground fault has been detected. The ground fault message
clears after system power is removed, the ground fault is
corrected, the GFP fuse is replaced by qualified personnel
(negative or positive grounded systems only), and system power is
restored. See the Conext MPPT 80 600 Solar Charge Controller
Installation Guide for more information.
InputOVFlt
(Input over voltage
fault)
F74 Input voltage has exceeded 600 VDC. Damage to the charge
controller is possible, so the fault will not clear until an operator
clears it manually using the SCP.
FanOVFlt
(Fan over voltage
fault)
F75 Fan voltage has risen above 13.8 V. The fan will cease operating,
but the charge controller will continue operating though it will
probably experience power derating. The fault will not clear until an
operator clears it manually using the SCP.
OutputOCFlt
(Output over
current fault)
F78 Three fast output (F71) or slow output (F73) over current errors
have occurred within 30 seconds.
The fault will not clear until an operator clears it manually using the
SCP.
