3_ On the opening pulse, the TWM base transmits a general activation command to the TWC sensors and
sets them to permanent reception status.
4_ When the automation is operating, the TWM base sends a signal to all programmed TWC sensors,
which in turn transmit the status of the sensitive edge and battery in sequence. The process is per-
formed continuously.
5_ If one or more TWC sensors are in alarm status, this condition is transmitted to the TWM base. The latter
opens the contact of the device in alarm status, causing automation shutdown.
6_ The TWM base remains active for a few seconds following automation shutdown, verified by means
of the input GATE OPEN INDICATOR. When the time interval elapses, the system returns to standby
status (point 1). The active phase is indicated by the red led (DL9) permanently lit.
7_ The presence of one or more TWC sensors with low battery charge is indicated by flashing of the rela-
tive green led.

INSTALLATION
All installation operations must be performed with the system disconnected from the power supply;
if fitted, the buffer battery must also be disconnected.
Preliminary checks
Carefully check that the operating parameters correspond to the data provided in the chapter "Technical
Specifications". If in doubt, do not use the product and request clarifications from the TAU technical assis-
tance service.
For fixture of the sensitive edge, follow the instructions supplied with the product.
To censure correct installation, proceed as follows:
1_ Position the TWC sensor in the vicinity of the sensitive edge, securing first the support bracket (1 fig.1)
by means of 2 screws (2 fig.1) suited to the gate structure. Insert the TWC board (3 fig.1) in the relative
supports on the base
2_ Connect the TWC sensor to the sensitive edge, routine the cables inside the gate (fig.2). Use cables
with sections of 0.5 mm².
3_ Locate the ideal position for the TWM base (the recommended position is normally inside the motor en-
closure or in the vicinity of the electronic control unit. If this is not possible, use the relative container and
place it externally in the vicinity of the operator or electronic control unit if the latter is not incorporated
in the gearmotor).
N.B. If the motor's cover is of metal (ex. Series BIG) it is necessary to put the TWM's base outside
the motor and use its special box.
