DESCRIPTION AND OPERATION
TAU Wireless is a device that allows to solve the problem of the electrical connection of the prox -
imity edges on moving and static gates. The system consists of:
1_ Base (TWM) that manages the sensors (via radio) and the controls from and to the gate panel
(via cable).
2_ Sensor (TWC) that sends the signal of the proximity edge (connected to it) with NC or resistive
contact, to be used as fixed and/or movable proximity edge.
All devices, both base and sensors, are fitted with a transceiver capable of receiving and trans -
mitting data on the standard 868 MHz frequency.
TAU Wireless can be used as part of a safety device sensitive to pressure (PSPE), through check -
ing the status of the proximity edge. The proximity edge, of the 8.2kohm constant resistance or
NC (normally closed) contact type, is continually monitored by the TWC sensor and its activation
status is transmitted to the TWM base. This base interprets the received information and trans -
mits it to the automation electronic unit.
The TAU Wireless system is compatible with all TAU control units.
TECHNICAL DATA
TWM card power supply 12/24V AC/DC
TWM card absorbed current 70 mA
TWC sensor power supply 2 x AA 1,5V batteries
Maximum load 20 m
TWM housing protection rating IP 45
TWC housing protection rating IP 45

INSTALLATION
The whole installation must be carried out with no voltage in the system; if a battery
backup is connected, disconnect it.
PRELIMINARY CHECKS
Check carefully that the use parameters match the data in the “Technical data” chapter. If in
doubt, don’t use the product and ask TAU technical service for clarification.
To install the proximity edge, follow the instructions accompanying the product.
For a correct installation, proceed as follows:
1_ Place the TWC sensor near the proximity edge fixing first the support bracket (1 in fig. 1) with
2 screws (2 in fig. 1) suitable to the gate. Insert the TWC card (3 in fig. 1) into the appropriate
base supports.
2_ Connect the TWC sensor to the proximity edge guiding the cables inside the gate (fig. 2). We
recommend 0.5mm² cables are used.
3_ Determine the best area for installing the TWM base (it is best to use the relevant housing
and locate it on the outside near the electronic control unit provided the latter is not built
into the gearmotor).
Note: If the motor casing is made from metal (e.g. BIG series), the TWM base must
be located outside the motor casing with the relevant housing. Even in the event the
casing is not made from metal, it is not advisable to position the TWM base near the
motor compartment or, more generally speaking, near metal objects as this might
