INITIAL OPERATION
BASIC SETTING
Proceed step by step. If you are not sure, start again at the beginning. Take sufficient time to make these settings.
1. Are all components required for operation connected? Motors, photocells, safety contact strip, stop switch.
2. Make sure that nobody is present in the range of the gates.
3. Close the gate/s and attach motor/s.
ART:
- Reference point or "passpoint" has to be adjusted to allow
a successful travel distance programming. The cams under
the cover of the ART need to be positioned correctly. The top
cam clicks the micro switch first and the bottom cam as second.
The micro-switches pushed by the cam shall not be pushed
(clicked) at the same time and shall be not pushed in the end
position of the gate. Twist the cams by using a pair of pliers or
with a large flat screwdriver.
- Disengage the gate using the release key for this adjustment.
- In case the drive arms are, after this installation step, re-located
the cam position has to be checked if a further adjustment is
required.
- Jumper settings for ART: Jumper SPEED removed! ART will not
work if speed jumper is in place (ON). By factory setting no
jumper is placed.
SUB (Underground):
- Jumper setting: Jumper SPEED in place for faster gate movement or removed if gate is heavy
or safest way of operating is required. Can be changed any time later after completion of the installation.
LYN-SCS Operator:
- Jumper setting: Jumper SPEED in place for faster gate movement or removed if gate is heavy or safest
way of operating is required. Can be changed any time later after completion of the installation.
Now connect the mains supply (230V) to the control board.
BASIC SETTING:
1. Press buttons P1, P2 and P3 simultaneously for approx. 2-3 seconds until yellow LED flashes.
2. Monitor the gate. Press and hold P1 for 1-2 seconds. The wing with motor 1 opens. If motor 1 closes, it is wired
incorrectly and the red and blue wires of the motor cable must be reversed. (Caution: Disconnect Power!)
Repeat steps 1 and 2. Leave gate/s in partially open position.
NOTE: General operation – if you release the button, the gate will immediately stop. By pressing the button again the gate will
move in the opposite direction until you release the button, and so on.
3. Press and hold P2 for 1-2 seconds. The wing with motor 2 must open. (Do not open gate completely, only short
distances.) If motor 2 closes, it is wired incorrectly and the red and blue wires of the motor cable must be reversed.
(Caution: Disconnect Power!)
Repeat steps 1 and 2. Leave gate/s in partially open position.
NOTE: The control board is active for this manual setting mode for approx. 20 seconds. If necessary, start again by pressing P1,
P2 and P3 simultaneously.
Now check the following:
1. SCS only: During opening the front housing must not touch the gate. Stop opening several times and check. If housing
touches the gate dimensions A/B must be checked and if necessary, underlay the gate pillar with flat washers in order to
enlarge clearance.
2. Both wings must open completely. Do not open the wings too far! If there are no stops, choose and mark a position for
maximum opening.
3. SUB (underground operator) only: Now adjust your hard-stop in the box.
Wait until learn-LED goes out (20 seconds after a button was pressed).
