The power delivered by the RF modules will remain stuck at
about 800-900 W for about 10 sec., After which it will begin
the regular ramp up and reach the set power.
LOC/REM Selector switch for setting the transmitter in remote or local
mode. In local mode the buttons and the controls via the me-
nus are active. In remote mode the buttons and the controls
via the menus are inhibited and the commands may be given
only remotely via the parallel interface or via the remote con-
trol software.
ALARM RESET Button to reset the alarm type FAULT or WARNING.
POWER LOWER Click this button to set the transmitter for supplying the nomi-
nal power level. A specific LED signals this setting. The value
that corresponds to the nominal level is set by the operator
using the menu settings (see 5.1.9)
NOMINAL POWER Click this button to set the transmitter for supplying the re-
duced power level. A specific LED signals this set-ting. The
value that corresponds to the reduced level is set by the ope-
rator using the menus. (see 5.1.9)
EXCITER
CHANGEOVER
Use this button to set the changeover system in manual or
automatic mode. The signaling LED turns on when the ma-
nual mode is selected. On performing a changeover, the exci-
ter connected to the amplifier is deviated toward the internal
dummy load and vice-versa. The operator must use the exci-
ters menu to perform the changeover in manual mode.
LED WARNING This LED indicates an attention condition (something is not
working properly, but the amplifier is still running)
LED FAULT This LED indicates a fault (the amplifier is blocked, and
required the intervention of an operator for the restoration)
LED WAIT This LED indicates the status of waiting (the amplifier is tem -
porarily disabled, but will be reactivated automatically when
the blockage is removed, or after a set period of time depen-
ding on the type of protection)
LED INT.LCK This LED indicates an external inhibition. This check is run
on the parallel interface (JP4/4)
LED TX-BUS INT These LEDs indicate the activity of the serial bus 485 throu-
gh which the CCU acquires the status every second of the
modules
LED RS-232
TX-BUS EXT
These LEDs indicate the communication between the CCU
and a PC connected to the RS-232
