WARNING: Disconnect primary power prior to servicing.
Troubleshooting
6.3 Software Revision
Each of the controller boards contains its own software (actually firmware) and
therefore each controller has its own software revision number or letter. It is
possible to get the revision numbers from the Diagnostics Display Menu labeled,
“SOFTWARE REV.” To check the software revisions press [MORE SOFTWARE
REV]. This will bring up the screen shown in Figure 6-1. The Firmware part
number is printed on a label attached to the ICs on the individual controller boards.
Before calling Harris Technical Support personnel it is a good idea to get the
software part number and revisions for each of the controller boards.

6.4 System Reset - TX_RESTART
Pressing the ON (LOW or HIGH) button on the transmitter will issue the
TX_RESTART command and try to return the transmitter to normal operation after
any fault has occurred. Note that this will not reset, or erase any of the faults stored
in the Fault Log in the Diagnostics Menu. Take the example of a failed and switched
out PA. The controller writes to memory the fact that the PA has failed and will not
try to turn it on again. To get the control system to try the PA again simply press the
ON (LOW or HIGH) button. The data concerning the failed PA will be reset and the
controller will try to operate normally, turning the previously defective PA on with
all of the rest of the PAs. Naturally, if it still has a problem it will be switched out
again. However, if the PA is fixed and re-installed, the controller will automatically
activate the PA.
6.4.1 3 Strike Routine
There are 4 faults in the transmitter that will initiate what is called a 3 strike routine.
They are:
• RFL_PWR - VSWR greater than 1.5:1
• ISO_AB_OT - The predicted temperature of the 5kW hybrid reject load is
greater than 130
