Note 1 Not used for single-leaf gates (the control unit automatically recognises whether there is only one motor installed).
Note 2 The “Stand-by all” is used to limit consumption; for further details on the electrical connections, refer to the “Stand-by all /
Phototest connection” paragraph, and consult the “PROGRAMMING” chapter for information on programming.
Note 3 The ALT (STOP) input can be used for NC contacts or 8.2 kΩ xed resistor contacts in self-recognition mode (see the “
PROGRAMMING” chapter).
Note 4 The AUX auxiliary input is programmed by default with the “Type 1 partial open” function, but can be programmed with one
of the functions shown in “Table 2”.

4.2.3 Operations for connection
To make the electrical connections (“Figure 7”):
1. remove the terminals from their housings
2. connect the various devices to the relevant terminals ac-
cording to the diagram shown in “Figure 7”
3. put the terminals back into their housings.
4. connect the power supply cable to points (A) and (B) and
secure it with the cable clamp (C) (“Figure 8”).
