7.3 MUTING FUNCTION.
7.3.1 DESCRIPTION.
As mentioned in the introduction, the muting function can be enabled with
any unit by simply connecting the F39-A11 muting lamp when the unit is
switched off.
This presence of this indicator is recognised every time the unit is
powered on. If its presence is detected, the unit will enable the
muting
function and if its presence is not detected the unit will ignore any request
for
muting . It is important to note that if the muting indicator is connected
during the F3SP-U5P-TGR is powered on, it will not be recognised and
the
muting function will not be enabled. Once enabled, if the indicator
develops a fault or is removed without first disconnecting the unit’s power
supply, it will signal an error as described in section 8.
To disable the
muting function, the unit’s power supply must be turned on
without the F39-A11 muting lamp connected.
In brief: this function, present on all units, is enabled and disabled by
means of the following simple procedure:
- Disconnect the unit’s power supply.
-
Connect the appropriate F39-A11 muting lamp and the muting sensors.
- Restore the unit’s power supply.
Bypass the muting function as follows.
- Disconnect the unit’s power supply.
- Disconnect the F39-A11 muting lamp and the muting sensors.
-
Restore the unit’s power supply.
