5.6 ADJUSTMENT OF LIMIT-SWITCH UNIT

The procedure for adjusting the closing and opening limit-

switch is as follows:

Completely close the industrial sectional door. 

Using trimmer 1, with the arrow facing down (closing), turn

clockwise to + or anti-clockwise to - until 

the closing limit-switch is activated.

Then set the industrial sectional door in opening position.

Using trimmer 1, with the arrow facing up (opening), turn

clockwise to + or anti-clockwise to - until 

the opening limit-switch is activated (see fig. 11).

Note for fine adjustment: the “+” symbol indicates backing 

away of the activator from the microswitch and therefore 

a longer stroke; the “-” symbol, on the contrary, indicates its 

approach and consequently a shorter stroke.

Final check of the open and closed positions.

Manually move the door in open and close position.

Ensure that the operator actually reaches the desired positions 

when opening and closing. If this does not occur, correct the 

limit-switch positions using trimmer  1. 

If used with 578D equipment, you can correct the closing stop 

point also by varying the post-end of travel deceleration.

5.7 IDENTIFYING ROTATION DIRECTION (operator with 844T 

equipment)

Figure 12 shows rotation directions Dir1 and Dir2. Motion in Dir1 direction is 

stopped by FC1 and motion in Dir2 direction by FC2. Consequently, if, for 

example, Dir2 is the rotation direction causing the door to close, FC2 deter

-

mines the stop closing point and FC1 determines the opening stop point.

 The OPEN command is normally associated with Dir1 motion - consult the 

equipment instructions if the rotation directions have to be reversed. 

The stop spring of the ring-nuts activating the limit-switches, is kept lifted up 

by the square - the latter must not be removed until the door stop points 

are adjusted.
