Using a PT Controller: Operation/Monitoring
10.2.4.3 PT Remote Fault Statuses
The following “Fault” statuses (Table 10-4) display on the remote to indicate that the PT is not
operating as intended. Refer to Section 10.3.2 for help in diagnosing/resolving the problem.
Note: The fault codes (example: “F12”) listed below only appear on the PT’s LCD display to iden-
tify the particular PT fault. These fault codes do not appear on the ME-ARC remote’s LCD display.
Table 10-4, PT Remote Fault Statuses
Status Description
No PV Input-PT
(F01)
The PT controller turned off because there has been no source of PV pow-
er detected on the PV terminals (i.e., PV+ to PV-) for more than 24 hrs.
Int Pwr Sup-PT
(F02)
The PT controller turned off because the voltage from the auxiliary power
supply in the controller has dropped to a low level.
High PV VDC-PT
(F03)
The PT controller turned off because a very high PV voltage (>187 VDC)
has been detected on the PV terminals (i.e., PV+ to PV-).
High Bat VDC-PT
(F04)
The PT controller turned off due to instantaneous high voltage (≥68 VDC)
detected on the battery terminals (i.e., BAT+ to BAT-).
BTS Shorted-PT
(F05)
The PT controller continues to run, but a problem with the BTS has been
detected (temp sensor has shorted). When this happens, the temp-com-
pensation is fi xed at a temperature of 77°F/25°C.
FET Overtemp-PT
(F06)
The PT controller turned off because the internal FETs (Field Effect Tran-
sistors) have exceeded their safe operating temperature (≥85˚C/185˚F).
HiBatt Temp-PT
(F07)
The PT controller turned off because the BTS has reached a very high
temperature (≥55˚C/≥131˚F).
Int Overload-PT
(F08)
The PT controller turned off because the current to an internal sensor has
exceeded the controller’s protection limits.
Int Phase-PT
(F09)
The PT controller turned off because one of the internal phases is faulty
or the phase signals are not in sync with each other.
BTS Open-PT
(F10)
The PT controller continues to run, but the BTS has opened or is no lon-
ger connected. When this happens, the temp-compensation is fi xed at a
temperature of 77°F/25°C.
Int Power-PT
(F11)
The PT controller turned off because the internal power control circuitry
reached its protection limits.
Ground Fault-PT
(F12)
The PT controller turned off because the GFP fuse has opened due to a
ground-fault condition.
ARC Fault-PT
(F13)
The PT controller turned off because a series ARC fault has been detected.
Int NTC-PT
(F14)
The PT controller turned off because the internal NTC (Negative Tem-
perature Coefficient) temperature sensor suddenly caused a large, unex-
pected temperature change.
Int Hardware-PT
(F15)
The PT controller turned off because a redundant hardware protection
circuit that monitors the internal temperature has exceeded a safe oper-
ating limit.
Ind Overtemp-PT
(F16)
The PT controller turned off because the charger’s inductors have ex-
ceeded their safe operating temperature (≥32˚C/≥270˚F).
Unknown Fault
##
(F##)
The PT controller turned off because the PT controller has sent a fault
code that cannot be determined by the ME-ARC remote.
