RACK FITTING OPERATIONS
IMPORTANT: If installing
MEC 200 Vertical
it is recommended to insert 2 mm shims between the
fixing bracket
and the
operator base
plate
before welding the rack to the gate, so that rack and gear mesh each other with an adequate clearance after that the shims have
been removed.
- Temporary fix MEC 200 on to the fixing bracket, perfectly levelled, by means of the 4 fixing screws C.
- MEC 200 outer gear must run idle: loosen (by 1 or 2 turns maximum) the hexagonal head screw by means of the
release spanner E 17
supplied with the equipment (pic.3).

2 mm SHIMS TO

THE GATE
- While fixing the
rack
it is required that the MEC 200
driving gear
is not connected with the gate and it can be made run idle by means
of the
release spanner E17
supplied with the equipment; the gate can be freely moved by hand.
- Temporary clamp the
rack
to the gate so that it can adequately mesh the
driving gear
: the
rack
must mesh the driving gear, idle, of MEC
200 in a very smooth way, without friction (pic. 4).
IMPORTANT: Before definitely fixing any component, make sure that the rack can mesh the
driving gear
of MEC 200 so that the whole
system, gate included, can be smoothly run by hand the full travel open and close without any friction.
- Remove the
2 mm shims
only after having fixed the rack. An adequete clearance between rack and gear has thus been achieved (pic. 4).

IMPORTANT
: respect the same rack pitch when joining
the rack bars. Use a spare rack bar as in the picture to
make sure that the junction has the same configuration.
