ATLAS Analogue
2.8 Intercabinet Connections
For multi-cabinet transmitter models DVA20000 and DVA30000, the intercabinet
connections will need to be installed next. See Intercabinet Wiring Diagram for
reference.
2.9 External Interlock Connections
The transmitter has inputs for up to four external interlocks on the External I/O Board.
More may be used by placing 2 or more interlocks in series. The transmitter is shipped
from the factory with jumpers in the External Interlock positions which will allow the
transmitter to operate with no external interlock connections. The Electrical Installation
drawing shows that Interlock #1, J18-1 to J18-2, is used by the 3 Port Patch Panel Panel
or possibly a motorized switch. The other three are to be used at the customers
discretion. The External Interlock circuit requires a closed connection between all of
the following terminals on the External I/O Board to turn the transmitter on:
•
J18 pins 1-2 (connected to 3 Port Patch Panel Panel or switch)
•
J18 pins 3-4
•
J18 pins 5-6
•
J18 pins 7-8
2.10 3 Port Patch Panel Panel Connections
Refer to the Electrical Installation drawing for Patch Panel Panel connections:
!
CAUTION:
ALWAYS SHUT THE TRANSMITTER OFF BEFORE REMOVING THE PATCH PANEL
TO PREVENT POSSIBLE DAMAGE TO THE CONTACTS.
IMPORTANT: This note only applies to systems without a patch panel or RF switch.
If no patch panel or switch is to be installed in the transmitter RF output line, then a
jumper must be placed on the External I/O board from J14-3 (RF_SW_A_STAT) to J14-1
(ground).
