you hold it down, press key 

+

:

•  If you release key 

+

 , the display indicates the name of 

the first function.

.

•  If you press key 

F

 (and hold it down), the display shows the 

name of the next function, and if you release it, the value 
that can be modified with keys 

+

 and 

-

 is shown.

•  When you reach the last function, press 

F

 to exit the program, 

and the display resumes showing the gate status.

The following table shows the sequence of functions 
accessible in ADVANCED PROGRAMMING:

MAXIMUM TORQUE AT INITIAL THRUST:

The motor operate at maximum torque 

(ignoring the torque setting) at start of move-
ment.  Useful for heavy leaves.

 = Active

 = Disabled

NOTE: Status 

 will be displayed after two consecuti-

ve triggers of the safe input or two consecutive obstacle 

detections from the inherent entrapment protection device 

(encoder). In this status the operator will also set off the audio 

alarm. Normal operation can only be resumed by breaking 

the stop circuit or resetting power.
