5.6 DCS 400R for Spare-Amp Switching
5.6.1 FUNCTIONAL
CHARACTERISTICS
The PROMATRIX Control System DCS 400R can be equipped with DCS 421R, DCS 422R and DCS 423R
modules, which add special power amplifier switching functions to spare-device switching.
Modules are installed in the DCS 400 19“ base unit. Using DCS 405R extension modules allows the
interconnection of two DCS 400 base units to provide spare-device switching of up to 68 power amps, depending
on the configuration.
5.6.2
DCS 421R CONTROL MODULE FOR SPARE-DEVICE SWITCHING
The module is installed at the rear side of the DCS 400 base unit in slot 1 (the slot all the way on the left hand
side). It offers continuous monitoring of the power amps connected as well as automatic spare-amp switching in
case of failure.
The DCS421R works in stand-alone operation offering monitoring capabilities for up to max. 68 power amps when
equipped with DCS 422R and DCS 423R modules accordingly. Alarm indication is provided via LEDs and fault-
contacts.
•
A single DCS 421R module can control up to 17 different DCS 422R / DCS 423R modules (two DCS 400,
each with a DCS 405R module linked via connection cord).
•
Self-monitoring via watchdog function.
•
6 binary switches for configuration and selection of service functions.
•
1 pushbutton for storing the configuration or for service functions.
•
Service functions and test-software for all modules connected.
•
3 LEDs (red – green – yellow) for test mode and system status indication.
Installation Note
Caution! Slot 1 (the slot all the way on the left hand side) has to be equipped with a DCS 421R control module
respectively with a DCS 405R extension module. The next Slots have to be equipped with DCS 422R / DCS 423R
modules always in ascending order (from left to right) and without empty slots in-between.
If two DCS 400 rack frames are used, in the first DCS 400 a DCS 405R extension module has to be equipped in
the first free slot after all other modules. In the second DCS 400 the DCS 405R has to be installed in slot 1.
When installing the module and establishing connections make sure to comply with VDE 0100 and EN 60065
regulations.
