You must follow all required safety precautions and instructions at all times. Review the safety brochure in-
cluded with the operator. If any pages are missing or unreadable, contact LINEAR at 1-800-333-1717 to request
additional copies.
Controls intended for user activation must be located at least six feet (6') away from any moving part of the
gate and where the user is prevented from reaching over, under, around or through the gate to operate the
controls. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use.
Do not adjust the circuit board current sensing feature too high. It should be adjusted high enough to keep the
gate from falsely triggering the sensing, but no higher than necessary for the gate to operate. Do not defeat
the purpose of this function!
DESCRIPTION OF FUNCTION
Provides 24Volt AC power for accessories.
Note: DC models will NOT have 24Volt AC power available.
Provides 24Volt DC power for accessories.
Opens the operator. Several accessories such as button stations, keypads, trans-
mitters and card readers can be wired to open.
Closes the operator. Use caution when wiring accessories to these terminals. The
gate must be clearly visible from the location of any accessories wired to
close.
Performs the single-button function which will alternate between open and close
or open, stop and close - depending on dip switch #3. (See page 9 for details.)
Stops the operator. If no stop button is used, a jumper is required across 2&4.
This function will cause a reversal when the gate is traveling closed and will travel
back to the fully open position. Loop detectors are often wired for reverse.
This function works only while the operator is opening. Any signal to this function
will cause the gate to stop, reverse a short distance, and then stop again. At this
time the auto close timer is disabled, and a renewed input will be required to start
the gate again. Should the gate be restarted and the signal occur again prior to
reaching a limit, the gate will stop again, and this time will sound the emergency
alarm and lock out.
This function works exactly like the OPEN OBSTRUCTION, except that it will only
work in the closing direction.
This function will keep the gate in its fully open position while the signal is present.
This is typically used with a loop and loop detector to keep a large swing gate
open while vehicular traffi c is passing through.
A 24Volt DC device such as a strobe light or alarm can be wired to these terminals.
Depending on dip switch #2, these devices will either begin three seconds before
the operator starts, or only while the motor is running. (See page 9 for details.)
