9.0 LED Indicators
The Protégé® SE Integrated System Controller includes extensive diagnostic indicators that
can
aid the installer in diagnosing faults and conditions. In some cases an indicator may have multiple
meanings depending on the status indicator display.
9.1 Status LED
The Status Indicator is located in the centre of the PCB and indicates the status of the Protégé®
SE Integrated System Controller. If the Protégé® SE Integrated System Controller is operating
normally the LED will indicate this by flashing at 1 second intervals.
9.2 Fault Indicator
The Fault Indicator is located in the centre of the PCB. During normal operation the fault indicator
is off. Flashing On will indicate that the Protégé® SE Integrated System Controller is operating in
firmware update mode and requires firmware to be downloaded.
9.3 Charge/Test Indicator
The Charge/Test Indicator serves two functions; it will indicate that a battery test is in progress and
that battery charging is being performed. When AC is present the battery charging current will be
indicated by a varying intensity level on this indicator. This indicator will also illuminate when a
battery test is in progress by illuminating brightly for 30 seconds every 10 minutes. The battery test
period is a programmable option in the Protégé® SE Integrated System Controller system options.
This LED is identified by the text ‘CHARGE/TEST’. This indicator does not function when AC is not
present.
9.4 Auxiliary OK Indicator
Auxiliary voltage is supplied to the AUX+ Outputs through the auxiliary fuse. If auxiliary supply is
normal the ‘AUX OK’ Indicator will be illuminated.
9.5 AC OK Indicator
When a valid AC Input is provided to the Protégé® SE Integrated System Controller the ‘AC OK’
Indicator will illuminate.
9.6 5V Isolated Power Indicator
The module communicates using an isolated RS-485 interface for optimal performance and this
requires an isolated supply on the N+ and N- terminals of the module network interface. When a
valid supply is input, the ‘5V ISO’ Indicator will illuminate.
