The Combined Interlocks submenu is entered by pressing the INTK submenu button on the main LCD screen.  
This submenu displays all the various interlocks for the RF amplifier. Each display item and control is described 
as to its meaning and function. 
The LCD displays a typical INTK submenu as follows: 
 
Figure 12 Transmitter On, Interlocks OK Screen 
The first line of the LCD shows the transmitter ON/OFF status and the resulting interlock status. If the transmitter 
has been turned ON and the Interlocks are OK, then the RF amplifier is indeed receiving the +32V power feed. 
Note that some interlocks will not be closed if the transmitter has been purposely shut down. An example of this 
would be the AMP1/AMP2 interlock. If the transmitter is shut down, the controller will shut down the fans since 
they are not needed and the fan interlock status for the amplifier would then normally be OFF. This makes it 
important to indicate to the operator the intended state of the transmitter as either ON or OFF to correctly interpret 
the subsequent status. 
The second line of the LCD shows the individual Amplifier interlock status. It will display a short message 
indicating the status of the amplifier interlock or fault.  If more information is desired regarding the amplifier 
interlock then the operator can select the AMP Interlock submenu to access this data. 
The third line of the display has a number of status lights with a legend describing the particular status underneath 
and all enclosed in a dashed line box. When the light is fully darkened, it indicates that this particular status is true 
and that interlock is closed (OK). When the light is hollow, it indicates that this particular status is false and the 
interlock is open (BAD). Certain related status are grouped together in the same box. The purpose of these status 
is to point the operator to the area that is currently causing the RF amplifier to be shut down. Each status is 
detailed below. 
 
3.7.1 
3.7.2 
AMP1 Interlock Status LED 
The status for the Amp1 interlock is determined from values sent from Amplifier #1 to the main controller via the 
serial stream.  The communications from amplifier #1 must be good for this status to show OK. 
•  Lit when Amp1 Comms is OK, Amp1 Ext1 and VSWR Interlocks are closed. 
•  Not lit when either Amp1 Comms is bad, Amp1 Ext1 is open or Amp1 VSWR Interlock is open 
 
AMP2 Interlock Status LED 
The status for the Amp2 interlock is determined from values sent from Amplifier #2 to the main controller via the 
serial stream.  The communications from Amplifier #2 must be good for this status to show OK. 
•  Lit when Amp2 Comms is OK, Amp2 Ext1 and VSWR Interlocks are closed. 
•  Not lit when either Amp2 Comms is bad, Amp2 Ext1 is open or Amp2 VSWR Interlock is open
