SEA bleu B200 RACK Manual De Instrucciones página 4

a) Prepare an excavation (450 mm x 300 mm x H min.160 mm) (17,72" x 11,81" x H min. 6,3") to be
covered with concrete type R425
b) Prepare the passage of a sheath for the electric cables inside the excavation
c) Insert the anchoring bolts into the concrete, letting them come out from the street level by 20 mm / 0,79"
in case of rack operator or by 26 mm / 1,00" in case of chain operator (Fig. 15 or Fig. 14)
d) Perfectly level the cemented base. When the concrete has dried, it will be possible to fix the operator on
the ground anchoring pins
!
For the rack operators, where possible, arrange a rise of at least 50 mm / 1,97" (Fig. 13)

a) Release the operator and open the leaf completely;
b) Fix on each gear rack element the support pawls with the appropriate lock screws, making sure to put
them in the upper part of the hole (Fig. 16) ;
c) Lean the gear rack element on the toothed pinion of the operator in parallel to the ground slideway of the
gate, as shown in Fig. 17 and electrically weld the central pawl B to the gate structure (Fig. 18).
Manually move the gate until pawl C is placed in front of the pinion and fix it through electric welding.
Repeat the same procedure for pawl A after having placed it in front of the pinion;

d) Make sure that all the gear rack elements are perfectly aligned and correctly placed (teeth must be in
phase). It's suggested to oppose an element to two aligned elements as shown in Fig. 19;
e) Repeat the above described operation for all the remaining gear rack elements which have to be
installed;
f) To avoid that the gate weights down the pinion (Fig.20) lift up the whole rack about 1,5 mm / 0,06 inches
Warning: Keep a gap of about 0,5 mm / 0,02 inches between pinion tooth and gear rack tooth;
g) Make sure that the gear rack works at the midpoint of the pinion along all the rack elements, if
necessary, adjust the length of the spacers
