FITTING THE GEAR RACK TO THE GATE
With heavy gates, the standard gear rack is to be double mounted and only the steel version 22x22 mm per bar is recommended.
It is to be fitted using support angles (not included) which are to be firmly welded to the gate following these instructions:
• Weld the single bars into compact double modules as indicated in Pic. 11.
• The total length of the gear rack must be equal to the gate travel, including the parts taken by the limit switch striking plates,
which are to be fastened on the rack itself.
• Provide a temporary setup for the gear rack on the gate and make sure there is a tip clearance of about 2 mm between the drive
gear and the teeth of the bar.
• Make sure the gear rack is perfectly aligned all along the gate travel before welding it firmly: test the correct alignment by manually
running the gate full track, Fibo 300 or Fibo 400 in disengaged mode, and make sure the drive gear turns smoothly without any
friction or jerking.
• Once satisfied with the outcome of the first running test, firmly weld the gear rack as indicated.
INSTALLING THE LIMIT SWITCH STRIKING PLATES
Gate stop, ie. stop of the drive gear, occurs when either striking plate meets the respective limit switches. Therefore the striking
plates are to be installed on the gear rack once the open/closed positions of the gate have been precisely assessed, ie. when the
gate is at the end/limit of the open and close cycles as required: it is recommended that the limit switches be activated a few
seconds earlier than the gate reaches the end of the travel where a complete stop is required (Pic.12).
