402 Installation
LEAF DELAY: You may choose to delay one leaf on
closing for overlapping gate leaves. Be sure the operator
on the leaf for delayed closing is connected to Motor 1.
On opening, the leaf connected to Motor 2 is delayed
2.5 sec.
Note: You cannot adjust this opening delay of
the operator connected to Motor 2. However,
you can turn off the delay by closing the jumper
labeled “Leaf Delay Disable”.
The closing leaf-delay time is adjustable from 0 to 28
seconds. Turn the potentiometer clockwise to increase
the time and counterclockwise to decrease the time.
Note: If one-leaf gate designs, be sure to set
the potentiometer for leaf delay to its minimum
(0 seconds).
NOTE: If the opening/closing time is set at less
than the leaf delay time, the delayed leaf closes at
the end of the closing time.
THE 402 OPERATOR
The FAAC recommended maintenance schedule varies
according to the frequency of use of the operators,
whether lightly used operators (once or twice an hour)
or heavily used operators (many cycles per hour),
operators used in a humid, salt air climate should follow
the heavy duty use schedule.
CHECK THE OIL.
To check the oil level correctly, remove the operator
from the gate leaf. With the piston rod completely
retracted and pointing to the ground, remove the rear
flange and look at the oil level in the casing of the
operator. The oil level should be about 3/4 in. (20 mm)
from the top edge of the operator casing. If the
operator is too full, it will bleed oil out the vent hole.
Light duty use: every 12 mo
Heavy duty use: every 6 mo
CHANGE THE OIL.
Light duty use: every 48 mo or 4 yrs
Heavy duty use: every 24 mo or 2 yrs
CHECK THE PRESSURE SETTINGS.
Light duty use: every 12 mo
Heavy duty use: every 6 mo
THE CONTROL PANEL
Keep the Control Panel free from spider webs, insects,
etc. Otherwise the Control Panel requires no
maintenance.
