The EXTERNAL INTERLOCK and EXTERNAL INTERLOCK RETURN contacts are
designed as floating ones. In this way more than one amplifier can be interconnected
in an interlock system with a common switch or a common loop.
Figure 3: Example of interlock safety loops
If this safety function is not used after thorough examination, the interlock contact can
be bridged in the Remote Control and Interlock connector. This is done using a
jumper from EXTERNAL INTERLOCK pin 8 to EXTERNAL INTERLOCK RETURN
pin 15.
Note: If the interlock connection is missing, the amplifier cannot be operated.
Finally, check that there is no message indicating an interlock error status on the
display. Now the amplifier is ready for use and can be operated either manually via
the front panel or via one of the remote control interfaces.
