Rack Fitting Operations - fadini MEC 200 Installation Manual

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).

- 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.
