9.7 Alarms
The alarms screen shows the status of all six alarms as either “OK” or “FAIL”.
“TALLY=” shows the total number of alarms that have occurred since last reset.
This value rolls over to zero when it reaches 65535.
“SWR=” shows the status of the SWR alarm. If the reflected power is greater
than the reflected power threshold then the SWR alarm will be activated and
“FAIL” will appear in this field.
“INT’LK=” shows the status of the interlock signal of the analogue remote control
port. If the interlock circuit is open then this field will be shown as “FAIL” and RF
power will be turned off.
“GEN=” shows the status of the RF generator module. If there is an error with
communication with the RF generator then “FAIL” will appear in this field.
“TEMP=” shows the status of the high temperature alarm. If the internal
temperature of the transmitter exceeds 85°C this field will show “FAIL” and RF
power will be turned off.
“AUDIO=” shows the status of the audio alarm. If more than 30 seconds have
elapsed with a modulation depth of 2% or less then this field will show “FAIL” and
the “AUDIO OK” relay contact of the analogue remote control interface will go
