MECHANICAL STOPS ADJUSTMENT
Models ASY feature an internal system for mechanical stroke limitation composed of adjustable and independent stops (parts
11 and 14 in fig. A), one for the opening stroke and one for the closing stroke (optional).
Using these internal stops can be convenient when there are no stroke end stops or when there is no other way to limit the
stroke of the gate leaf. Where permitted by the installation it is anyway advisable to use or install gate leaf limit stops.
The adjustment is extremely simple:
- remove the screws (part 6 in fig. A) and remove the cover (part 4 in fig. A).
- fit the mechanical stop to the lead screw (fig. C) while keeping the fixing screws backed off.
- move the leaf towards the actuator maximum stroke limit and fully tighten the screws of the mechanical stops
- perform opening and closing cycles to check the stops are correctly positioned and then refit the actuator cover.
RELEASE AND LOCK PROCEDURE (irreversible models only)
These two operations are only required in the event of a fault or electrical power failure; the user or person responsible must be
instructed by the installer, who will provide them with a copy of these instructions, which must be kept in a safe place together
with the release key.
Before performing either of these procedures, make sure you disconnect the entire automation from the electrical
supply, even if it is currently unpowered due to an outage.
Any electric locks must be specified and released for manual operations.
RELEASE: 1) disconnect the electrical supply; 2) open the rubber cap, insert the key and turn it clockwise; 3) raise cover; 4)
grasp the lever and turn it towards the front of the actuator; the gate leaf can now be moved manually.
5) The leaf can remain unlocked and the cover can be refitted by simply removing the lever.

LOCK: 6) grasp the lever and rotate towards the rear of the actuator; at this point the leaf is locked and can only be moved
electrically.
7) After this operation always close the cover; 8) and turn the key to lock it in place; 9) take care to reclose the rubber cap
protecting the lock.

For REVERSIBLE models the gate can be operated manually after having released exclusively any electric locks
fitted.
