2.5 ALARMS CARD
This module (3 Photo 1) is composed of a board mounted on the front panel,
in left position, as shown in Photo 1.
On this board, the electronics detect any system anomaly such as excessive
SWR antenna (the internal SWR is not actived); over-temperature etc.
This module will also, whenever possible, reset the system to its original
conditions, after a fault has accused.
2.6 TELEMETRY CONNECTOR
The telemetry connector (3 Fig.2) is placed on the rear panel in the right
side as shown in Fig.2.
Thanks to this connector the essential parameters of the amplifier are
externally available for remote measurements purposes.
