Table 10-4, Pt Remote Fault Statuses - Magnum Energy ME-ARC50 Owner's Manual

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.

Using a PT Controller: Operation/Monitoring

Table 10-4, PT Remote Fault Statuses

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.
The PT controller turned off because the voltage from the auxiliary power
supply in the controller has dropped to a low level.
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-).
The PT controller turned off due to instantaneous high voltage (≥68 VDC)
detected on the battery terminals (i.e., BAT+ to BAT-).
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.
The PT controller turned off because the internal FETs (Field Effect Tran-
sistors) have exceeded their safe operating temperature (≥85˚C/185˚F).
The PT controller turned off because the BTS has reached a very high
temperature (≥55˚C/≥131˚F).
The PT controller turned off because the current to an internal sensor has
exceeded the controller's protection limits.
The PT controller turned off because one of the internal phases is faulty
or the phase signals are not in sync with each other.
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.
The PT controller turned off because the internal power control circuitry
reached its protection limits.
The PT controller turned off because the GFP fuse has opened due to a
ground-fault condition.
The PT controller turned off because a series ARC fault has been detected.
The PT controller turned off because the internal NTC (Negative Tem-
perature Coefficient) temperature sensor suddenly caused a large, unex-
pected temperature change.
The PT controller turned off because a redundant hardware protection
circuit that monitors the internal temperature has exceeded a safe oper-
ating limit.
The PT controller turned off because the charger's inductors have ex-
ceeded their safe operating temperature (≥32˚C/≥270˚F).
The PT controller turned off because the PT controller has sent a fault
code that cannot be determined by the ME-ARC remote.
