B Output relay closed (ORC, logic);
C RF Arc fault (ARCF, logic);
D Control grid current too high (G1C, logic);
E +24 VDC power supply error (PSE, logic);
F Low airflow (LAIR, logic).
For instance, "1ATR4B" in the first group would mean that the latest auto-protection (1A) 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.
Detailed electrical schematic diagrams are available from ACOM or from your dealer on
request.
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 Section 7.3 Storage and Shipment.
