4_ Close the board housing with the relative cover (4 fig.1).
5_ There are 2 installation configuration options: As a safety device on closing (1-2 fig.3) and/or on opening
(3-4 fig.3). In situations 1 and 2, the TWM board output relay must be connected to the photocell input of
the panel controlling the automation (both for the mobile and fixed sensitive edges), and in series to the
photocell/s themselves (see diagram in fig.4) so that the sensitive edges are active during the closing
phase. In situations 3 and 4, the TWM board output relay must be connected to the CF (fixed edge) input
of the panel controlling the automation (both for the mobile and fixed sensitive edges), so that the sensi-
tive edges are active during the opening phase or in series to other fixed sensitive edges (see diagram
in fig. 4).
6_ Note that only one TWC can be fitted on a sensitive edge active during the opening phase and only
one on a sensitive edge active during the closing phase (in the cases of both fixed or mobile sensitive
edges). Taking fig. 3 as an example, sensitive devices 1 and 2, or sensitive edges 3 and 4 cannot be in-
stalled on a single TWM base. On the contrary, sensitive edges 2 and 3, or 2 and 4 etc. can be installed
on a single TWM base.
N.B. It is always recommended to use the pre-flashing function on the automation's control
board.
CONNECTIONS (fig.4)
CONNECTIONS TO TERMINAL BOARD (TWM)
1 - 2 12/24 Vdc/Vac power supply input
3 Not connected
4 GATE OPEN INDICATOR input
5 Contact common
6 Not connected
7 Not connected
8 SENSITIVE EDGE – fixed edge contact output (5 = COMMON - 6 = SENSITIVE EDGE), NC
normally closed contact (connected to led DL1).
9 SENSITIVE EDGE – mobile edge contact output (5 = COMMON - 9 = SENSITIVE EDGE), NC
normally closed contact (connected to led DL2).
J2 Power supply selection: Jumper closed for 12 Vac/dc, jumper not inserted for 24 Vac/dc.
J3 Selection of connection to input of sensitive edge of control unit J3 inserted if the control unit has
the provision for an ON/OFF type input; do not insert jumper on J3 if the input is resistive type
at 8.2 KΩ.
J4 Bridge it if powered with DC. Do not bridge if powered with AC.
CONNECTIONS TO TERMINAL BOARD (TWC)
1 - 2 SENSITIVE EDGE (or RESISTIVE SENSITIVE EDGE) NC contact input – fixed or mobile
edge.

1-2-3 System's transmission frequency
OFF: no resistive sensitive edge

ON: resistive sensitive edge
PROGRAMMING
Perform a cancellation procedure before starting programming (see next paragraph). The programming
phase can only be performed after the above.
CANCELLATION PROCEDURE
Sensors: Press the cancel pushbutton for at least 5 seconds (see figs. 4-5).
Base: Press the programming pushbutton until the red led (DL9) illuminates, flashing first and then
remaining permanently lit, and then turns off. Release the pushbutton when the led turns off.
