Error Screen
From the Charge Controller Stats screen, the <Next> soft key proceeds to the Charge Controller
Error screen. This screen displays fault conditions for the FLEXmax 100. If an item displays Y, the error
is active. Some errors accompany a controller shutdown; others simply report status. See the
Troubleshooting guide on page 57 for more information on all items.

Temps Screen
From the Charge Controller Error screen, the <Next> soft key proceeds to the Charge Controller
Temps screen. This screen shows the internal temperature. The measurement is used for fan control,
temperature derating, or to trigger a shutdown in extremely hot temperatures. If any of these events
occur, this screen can be used to check the temperatures.
Figure 31 Temps Screen
Soft Keys:
<DataLog> proceeds to the Datalog screen (see page 39).
<Temps> proceeds to the Temps screen (see Figure 31).
<Back> returns to the previous screen.
<Port> cycles through each device connected to the network.
Screen Items:
VOC Too High
: The controller has shut down because the array V
oc
has exceeded its upper limit.
Upper limits: 24-volt system = 275 vdc, 36-volt system = 283 Vdc, 48-volt system = 290 Vdc
This error can clear automatically.
Over Temperature
: The FLEXmax 100 is too hot to operate and has shut down. This error can clear
automatically. See the temperature readings in Figure 31.
Shorted RTS
: The Remote Temperature Sensor (RTS) has malfunctioned. The controller will not shut
down, but it cannot compensate for temperature.
GFDI Fault
(accompanied by the
F
AULT
LED indicator): The GFDI circuit has shut down the charge
controller. See pages 15 and 30 for more information.
Fault Input Active
: The Rapid Shutdown terminals have detected an open circuit and shut down the
controller. This is not a controller error but a deliberate action. See pages 22 and 24 for more information.
This error requires a manual reset of the external Rapid Shutdown device as noted on page 25.
Reduced Performance
: The internal temperature sensor (see below) has failed. If a failure is detected,
the controller will operate with a maximum output of 20 Adc.
Over Current Fault
: The controller has shut down because more than 120 Adc was sensed flowing to the
batteries (or more than 80 Adc to the array). This requires a manual reset as described on page 57.
Soft Keys:
<Back> returns to the previous screen.
<Port> cycles through each device
connected to the network.
