PROCEDURES
6.1
SETTING THE INTERNAL DIP-SWITCHES
•
Disconnect the SLC’s power supply and remove the connector side
of the transceiver, so that you can reach the two banks four-way
dip-switches located there.
•
Use a suitably sized screwdriver to set the dip-switches as per the
required configuration according to the following tables.

7 MUTING AND OVERRIDE FUNCTIONS
7.1 GENERAL
INFORMATION
The
muting
and
override
functions
enable the SLC to be bypassed for
operational requirements. As required by current standards, the SLC is
provided with inputs for the activation of these functions. It should however be
remembered that these functions basically override the system and they
should therefore be used with due care.
7.2 MUTING
FUNCTION
As mentioned in the introduction, the
muting
function can be enabled with any
SLC by simply connecting the LMS muting indicator when the SLC is switched
off.
The presence of this indicator is recognised when the SLC is switched on. If
its presence is detected, the SLC will enable the
muting
function and if it is not
present the SLC will ignore any request for
muting
.
It is important to note
that if the
muting
indicator is connected when the SLC is already
connected to the power supply, it will not be recognised and the
muting
function will not be enabled.
Once enabled, if the
LMS muting
indicator
develops a fault or is removed without first disconnecting the SLC’s power
supply, it will signal an error with the
muting
light, as described in section 10.
To disable the
muting
function, the power supply must be turned on without
the LMS muting indicator connected.
In brief: this function, present on all SLC s, is enabled and disabled by means
of the following simple procedure:
-
Disconnect the SLC’s power supply.
-
Connect the appropriate
LMS muting indicator
and the muting
sensors (see section 6)
-
Restore the SLC’s power supply.
Bypass the muting function as follows.
-
Disconnect the SLC’s power supply.
-
Disconnect the
LMS muting indicator
and the muting sensors (see
section 6)
-
Restore the SLC’s power supply.
