ETL600 1KHW001489-EN ABB Switzerland Ltd
power amplifier 8 and an additional transmit filter 9. A carrier combiner
module 10 then combines the signals of both amplifiers into the 80 W
output signal.
For supervision of the equipment, three alarm contacts are available
and the equipment status is indicated with LEDs on the front. An
optional alarm relay module 5 can be mounted in the rear which
features additional 8 alarm relays, giving a total of 11 alarm relay
contacts.
For programming, testing, commissioning and in depth supervision of
the equipment, the user interface program HMI600 - a Windows
®
application - is needed, which is an integrated part of ETL600. Access
via dial-up modems and the intranet/internet is also supported by the
HMI600 program. For internet access, the server program SVR600,
available as an option, is required in addition to the HMI600. Refer to
chapter 4 for more information about HMI600 and SVR600.
For the supply of the modules, the subrack 7 has to be equipped with
a DC-DC-converter 6 and each of the subracks 14 with a power supply
module 13. The power supply voltage is 48 V DC with module B5LA
and 115 V AC or 230 V AC with module B5LC. Other supply voltages
require an external converter.
