The rod balancing with spring
After assembling of the gate is necessary check the balancing of the rod with the spring / springs
choose by previous table. Every piece of make road gate is assembled for specified rod length, rice
time, spring balancing.
As far as is used other length of the rod, than is specified on manufacture label, you need to read
following instructions:
The spring balancing you can do with installed final length rod including all accessories, with spring /
springs (according the table) disconnected pull between gearbox and lever. Let's verify the balancing
of the rod with tensing or alternatively unfastening of the spring through spring bottom bolt. Balanced
rod - spring system has in all moving area the easy running and there's no need to help with hand
more then slightly.
After the spring balancing use the pull for connecting the gearbox to lever, check the place of 90o
sector and feeze the safety nuts. These operations has grand amount at views of rod running fluency
and mechanical stress limitation of all gate case deals.
Note: The verifying of spring balancing is necessary after every change of rod length, type of rod,
adding of any accessories etc.
Setting of limit switches
The limit switches are check the run of the rod and guarantee switch-off the motor in last places of rod
running. The limit switches are located on the console near the gearbox. Switching flags are attached
with screws M5 (imbus type) on the bracket which is situated in outgoing gearbox axis.
Generally the limit switches guarantee 90oangle of rod running and coming of gearbox lever near the
dead position, like with 180oangle of running. It means, that the rod has zero angle speed in last
places of rod running. The system is designed in so far that the mechanical limits are not required.
Emergency opening
During using of road gate can arrive the situation, when is necessary open the gate alternatively (f.e.
the power supply is aborted).
! WARNING ! Emergency opening or closing do only
with shut-down power supply switch ! Harm hazard !
In this case you need apply the key on opposed motor site then pulley.
There are the flats put on the key. With swinging of the key you can move with gate rod.
Periodical adjustment
Automatic road gate is designed and made as without service device. For permanent error free
function we advice advise to execute these advances every three working months:
1) verify the earthing point - the screw, and in
case of findings feeze the nut
2) verify visualy of all threaded joints and in
case of findings feeze all needed
3) apply the WD 40 alternatively alike on the
functional area articulated bearing of the lever
4) verify the belt tension, whom the deflection
must be amount 10 mm (like on the picture),
in case of findings adjust the tension
