The LED display will only show that a PA module has faulted. The specific fault condition is indicated on the
T-4180 Module Status screen #2.
When the fault condition disappears, the faul
t LED’s will turn OFF on the next key – or in case of a critical
fault
– the power has been turned OFF and ON again.
Power Supply Module:
The 50VDC supply voltage is monitored by the microprocessor in the System Controller module. A power
supply fault is declared whenever the supply voltage falls outside the voltage range of 45V to 53V.
Transmitter keying is inhibited if the supply voltage is above 53V in the Power Supply module.
With a fault in the 50VDC power supply, the System Controller and PA module LED display is as
shown below.

When the fault condition disappears, the fault display is cleared on the next key.
Note: The Power Supply module will start current limiting at approximately 325A and enter
“constant current mode” of operation. Excessive current draw does not necessarily indicate
a failure of the 50VDC supply but may be caused by the operating conditions that affect the
efficiency of the Transmitter.
Combiner Module:
a.
A fan fault is declared if, when keyed, the fan current is above or below specific hardware set limits.
b.
A temperature (TEMP) fault is declared when the Combiner module heatsink temperature exceeds
approximately 100°C.
With a fault in the Combiner module, the System Controller and PA module LED display is as shown below.
