PREPARATION
VEHICLE LOOPS
The vehicle loops allow the gate to stay open when vehicles are obstructing the
gate path. Suggested for vehicles 14 feet (4.27 m) or longer. Vehicle loops are
not required but are recommended.
! !
Entrapment protection devices are required to protect against any entrapment
or safety conditions encountered in your gate application (refer to page 5
for more details). Install warning signs on both sides of the gate.
Gate must be constructed and installed according to ASTM F2200 standards
(refer to page 4). Gate must fit specifications of operator (refer to
specifications).
Proper grounding gives an electrical
charge, such as from an electrical
static discharge or a near lightning
strike, a path from which to dissipate
its energy safely into the earth.
Without this path, the intense energy
generated by lightning could be
directed towards the gate operator.
Although nothing can absorb the
tremendous power of a direct lightning
strike, proper grounding can protect
the gate operator in most cases.
