8 OPERATING
PROCEDURES
8.1
SETTING THE INTERNAL DIP-SWITCHES
x
Disconnect the barrier’s power supply and remove the side on the
connector side of the receiver, so that you can reach the two banks
four-way dip-switches located there.
x
Use a suitably sized screwdriver to set the dip-switches as per the
required configuration according to the following tables.
8.1.1
SELECTION OF RESET MODE
Single switch number 4

OFF Manual
ON Automatic
8.1.2 RELAY
MODULE
MANAGEMENT
Single switch number 3
Function
OFF Disenabled
ON Enabled
VERY IMPORTANT WARNING!!!
In every unit are present two different dip-switch banks and that two
banks must be set in the same way.
The two dip-switches on the receiver side must have the same
configuration.
The configuration of the two, number 3 dip-switches (relay module
management) on the transmitter side must be the same as the
configuration of the two, number 3 dip-switches on the receiver side,
therefore, if you alter these dip-switches on the receiver you must also
alter those on the transmitter by removing the side panel on the
connector side.
If the number “3” dip-switches are not identical, the RX-TX system will
not work.

9 MUTING, OVERRIDE AND FLOATING BLANKING
FUNCTIONS
9.1
GENERAL INFORMATION ON THE THREE FUNCTIONS
The
muting, override
and
floating blanking
functions enable the
barrier (or a part of it) to be bypassed when it is working for
operational requirements. As required by current standards, the
barrier 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.
9.2 MUTING
FUNCTION
As mentioned in the introduction, the
muting
function can be enabled with any
barrier by simply connecting the LMS muting indicator when the barrier is
switched off, as described in section 6.
The presence of this indicator is recognised when the barrier is switched on. If
its presence is detected, the barrier will enable the
muting
function and if its
presence is not detected the barrier will ignore any request for
muting
.
It is
important to note that if the
muting
indicator is connected when the
barrier is already connected to the power supply, 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
barrier’s power supply, it will signal an error with the
muting
light, as described
in section 10.
To disenable the
muting
function, therefore, the barrier’s power supply must
be turned on without the LMS muting indicator connected.
In brief: this function, present on all barriers, is enabled and disenabled by
means of the following simple procedure:
-
Disconnect the barrier’s power supply.
-
Connect the appropriate LMS and the muting sensors (see sec. 6 )
-
Restore the barrier’s power supply.
Bypass the muting function as follows.
-
Disconnect the barrier’s power supply.
-
Disconnect the LMS device and the muting sensors ( see sec. 6 )
-
Restore the barrier’s power supply.
