Both of the following procedures must be conducted
three times.
Force learning runs:
▶
Press circuit board buttonT once.
The operator automatically moves into the OPEN
end-of-travel position.
▶
Press circuit board buttonT once.
The operator automatically moves into the CLOSE
end-of-travel position.
4.3.1 Setting the force limit
CAUTION
Danger of injury due to the force value being set too
high
If the force value is set too high, the force limit is less
sensitive and the gate will not stop on time when closing.
This could lead to injuries and damage.
▶
Do not set a force value that is too high.
NOTE:
Due to special fitting situations, it can, however, happen that
the previously taught-in forces prove inadequate, which can
lead to undesired reversing. Readjust the forces in such
cases.
The force limit of the gate system is set via a potentiometer
that is labelled "KraftF" on the control print (see Figure9.1).
1. The increase in the force limit is a percentage increase in
relation to the taught-in values where the setting of the
potentiometer denotes the following force increase:
Full left + 0 % force
Centred +15 % force
Full right +75 % force
2. The taught-in force setting must be checked using a
suitable force measuring device to make sure that the
values are permissible within the application scope of the
European Standards EN12453 and EN12445 or the
corresponding national regulations.
4.3.2 Operator speed
If the force measured with the force measuring device is still
too high when the potentiometer is turned to full left, this can
be changed by reducing the travel speed (see Figure 9.2).
Adjusting the speed:
1. Set DIL switch15 to ON.
2. Perform three successive force learning runs
(seesection4.3).
3. Check again using the force measuring device.
4.3.3 Switching off the force limit
NOTE:
Not for use in countries with EU directives!
The force limit can be switched off by snipping through the
BR1 wire jumper on the control print.
If no safety devices are connected (DIL switches3 – 6 to
OFF), the operator will only work in press-and-hold operation.
If 8k2 resistance contact strips are connected
(DILswitch3 – 6 to ON) the operator will work
in-press-and-release operation without force limit.
Deactivating the force limit:
1. Perform a factory reset (see section10).
2. Snip through the BR1 wire jumper.
3. Set DIL switch2 to ON and teach in the operator again
(see section4.2).
If the wire jumper is snipped through during set-up or during
gate travel, this will not have any effect on the function.
NOTE:
Once you have completed the teach-in procedure, the door
system can only be operated using an external button.
• A permanent contact at terminals 20 + 21 moves the
operator in the Open direction
• A permanent contact at terminals 20 + 23 moves the
operator in the Close direction
Reactivating the force limit:
1. Perform a factory reset (see section10).
2. Connect the BR1 wire jumper.
3. Set DIL switch2 to ON and teach in the operator again
(see section4.2).
4.4 Changing the starting point for slow speed
when opening and closing
The slow speed length is automatically set to a basic value of
approx. 500mm before the end-of-travel positions after the
end-of-travel positions have been taught in. The starting
points can be reprogrammed from a minimum length of
approx. 300mm up to the entire gate length (see Figure9.3).
Changing the starting points for slow speed deletes the
already taught-in forces and they must be taught in again
after the changes have been made.
Changing the starting points:
1. The end-of-travel positions must be set and the gate is in
the CLOSE end-of-travel position and DIL switch2 must
be set to OFF.
2. Set DIL switch12 to ON.
3. Press print buttonT.
The gate will travel normally in press-and-release
operation in the OPEN direction.
4. When the gate passes the desired position for the start of
slow speed, briefly press print buttonP.
The operator will move at slow speed for the remaining
distance until in the OPEN end-of-travel position.
5. Press print buttonT again.
The gate will again travel normally in press-and-release
operation in the CLOSE direction.
6. When the gate passes the desired position for the start of
slow speed, briefly press print buttonP.
The operator will move at slow speed for the remaining
distance until in the CLOSE end-of-travel position.
7. Set DIL switch12 to OFF.
The slow speed starting point settings have now been
completed. The green LED flashes to signal that the forces
must be taught in again.
NOTE:
The starting points for slow speed can also be set to "overlap";
in this case, the entire gate movement is in slow speed.
