SB0 - tests made in Stand-By, during the warm-up period or while entering Stand By (from
Operate); SB2 - tests made during Stand-By, after the warm-up period;
PR0 - tests made while entering Operate;
PR2 - tests made during Operate;
TR0 - antenna relay tests made while changing from Tx to Rx (during Operate)
TR2 - antenna relay tests made while changing from Rx to Tx (during Operate)
TR4 - antenna relay tests made during Tx (Operate mode)
TR6 - antenna relay tests made during Rx (Operate mode)
c) The last symbol of the first group designates the kind of the input parameter, which
caused the protection to trip. The abbreviations in brackets below are the signal
names/designations according to the CONTROL PCB electrical schematic diagram and
signal type:
1
- peak forward power (pfwd, analogue)
2
- reflected power (rfl, analogue)
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 - arc fault (ARCF, logic)
D - control grid current too high (GIC, logic)
E - +24VDC power supply error (PSE, logic)
F - low airflow (LAIR, logic)
For instance, "IATR4B" in the first group would mean that the last auto-protection (IA)
tripped by the antenna relay tests made during 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.
