WARNING: Disconnect primary power prior to servicing.

Section 6 Troubleshooting
IMPORTANT:
It is very important to note that once the HDE-100 Exporter is properly connected
and configured, the following HDx-FM settings on the Output Setup page 1/4
must be made for normal HD operation.
HD Carriers: ENABLED
Exgine Input: EXPORTER
Exgine Output: NORMAL
6.11.3 Turning the Transmitter ON with No Power Output
There are times when it is advantageous to be able to turn the transmitter on with the RF
power output at zero watts. This would allow the power to be slowly ramped up for
monitoring of temperatures, currents, voltages and VSWR without over-loading and
tripping the faults circuits. To do this, press the HIGH or LOW ON button and then
quickly press and hold the LOWER button for at least 10 seconds. The transmitter will
come on but the output power will be at zero.
6.11.4 Asterisk and Pound Signs(*, #)
The asterisk and the pound sign characters are used in some of the metering menus of
the Diagnostics Display. If an asterisk (*) shows up in a metering menu, it means that
there is no data being received for that reading. The pound sign will only be used in the
Vg (Gate Control Voltage for the individual PAs) menus and signifies that there has
been a crossover (this is a condition where one PA Controller crosses over and mutes
the PAs associated with another PA Controller).
6.12 Master Controller Faults
The following is a listing of the faults which are handled by or merely related to the
Master Controller. A quick reference for each of these faults is given in Table 6-2 on
page 6-46.
6.12.1 THERMISTOR, Fault
The Thermistor fault is detected if a thermistor temperature reading is 5° C below the
ambient temperature, provided the ambient temperature is above 25° C.
This fault protects against a thermistor (temperature sensor) circuit being open. It can be
caused by an actual open thermistor but is more likely an open connection between the
thermistor and the controller board monitoring the thermistor. The thermistors are used
on all amplifiers, iso loads, and the power supplies to sense temperatures and use pull
up resistors to +V. As the temperature increases, the resistance of the thermistor goes
down, lowering the voltage on a detector input, which gives an increased temperature
