ZK300DC SWING GATE OPERATOR USER'S MANUAL
Stop block –open position
After the gate reaches the desired angle (90°or 105°), ensure 5-10mm space exists

between the gate and stop block See Fig.4. This margin is required to prevent the
gate from bumping on the stop block.
Fix the stop block to the ground with expansion bolts, add pad if necessary.

After mounting the operator, with the key unlocked, move the gate, verify that it

stops at the proper position.
Electric lock
An electric lock is provided for installation for gate lengths greater than 1.5 meters.

To install the base plate of the lock, place the base plate between the two gates,

determine the location, mark and drill the holes.
Fix the base plate to the ground with 3 screws, make sure the gate is higher than

base plate and that the lock pin can fit tightly in the hole in the plate.
Weld the steel plate of the lock to the primary gate, and then fix the lock to the steel

plate. See Fig.11 to determine the height of the electric lock.
Stop plate (see Fig.11)
The pair of gate sections will not start simultaneously. The gate section with the lock

will start to open earlier than the other gate section, so that both sections can be
locked properly.
With the gate in the desired closed position.

Weld a stop plate on the gate section without the lock.

A plate or tab can be welded on the gate section with the lock so that when it closes,

it will trap the gate section without the lock between itself and the base plate, thus
locking both gate sections.
