3 - input (drive) power (inp, analogue)
4 - peak anode alternate voltage (paav, analogue)
5 - screen grid current (g2c, analogue)
6 - plate current (ipm, analogue)
7 - high voltage (hvm, analogue)
8 - exhaust air temperature (temp, analogue)
9 - drive power exists (*GRIDRF, logic)
A - antenna power exists (*PANT, logic)
B - output relay closed (ORC, logic)
C - RF arc fault (ARCF, logic)
D - control grid current too high (G1C, logic)
E - +24VDC power supply error (PSE, logic)
F - low airflow (LAIR, logic)
For instance, "1ATR4B" in the first group would mean that the last auto-protection (1A) tripped
by the antenna relay tests made during the Tx - Operate mode (TR4), and the "output relay
closed - ORC" signal was failing (B).
The next five groups of symbols carry information about the analogue and logic values as
measured by the micro-controller at the moment of auto-protection trip.
* Additional information is available from ACOM or from your dealer on how to interpret these
values. Using an Excel application available from ACOM or your dealer free of charge, and a
PC, you can decode these signatures.
In case it is necessary to ship the amplifier please see S.7-3.
