: STARTING THE OPERATOR
SETTING THE OBSTRUCTION DETECTION /
SENSITIVITY
The operator is
equipped with an
o b s t r u c t i o n
detection circuit
which will detect
M

obstructions in the
gate's path. See
Figure 19. The
sensitivity can be
i n d e p e n d e n t l y
adjusted for OPEN
and CLOSE with
the potentiometers
on the controller board labeled,
"OVERLOAD FORCE". Turning a
potentiometer clockwise decreases the
s e n s i t i v i t y a n d t u r n i n g i t
c ount e rclo c kwis e i n cr eas es t h e
sensitivity.
The LP1000 is shipped from the factory with
the potentiometers at their most sensitive setting. Turn the potentio-
meter 1/4 turn clockwise to prevent the overload circuit from tripping
due to the gate's inherent friction.
(See FINAL SETTING OF THE OBSTRUCTION DETECTION
SENSITIVITY, P 16.)
SETTING THE SWITCH SELECTABLE OPTIONS
There are three (3) option selection switches on the LP1000 controller
board that result in four (4) switch selectable options. Please review
Figure 20. The switches are contained in a 3-pole dip switch package at
the bottom right of the board. The text that follows describes each of
the options they select.
NO-LOAD TEST MODE
To run/test the LP1000 operator
when it is not connected to a gate
leaf, turn all of the switches to
the “ON” position. The LP1000
can then be operated without a gate leaf attached for 20 complete
cycles. If more that twenty cycles are attempted in the test mode the
operator control board changes to a “sleep” mode and a low pulsed tone
is heard from the audible output. You can reset the operator for a
renewed 20 test cycles by turning the power off and back on again. To
return to normal operation turn one of the switches to the “OFF”
position, then set all the switches to the desired mode of operation as
described in the text that follows.
AlarmAble™ OPEN/CLOSE PUSH BUTTON
ENABLE/DISABLE (PATENT NO. 6,611,205)
Switch S1 controls the Push Button Enable/Disable Feature.
SWITCH 1 OFF:
Activating the Open or Close buttons the gate will
open or close fully. Activation of the Open while the gate is closing
will cause it to re-open. Activation of the Close while the gate is
opening has no effect. Continuous activation of an opposing button
while the gate is on a limit will prevent operation in that direction.
Continuous signal required to move the gate when in the alarm mode.
SWITCH 1 ON:
Gate does not respond to pushbutton input when in
the normal mode. Continuous signal required to move the gate when in
