AZ/EL PHYSICAL LIMIT SWITCH PRE TEST
LSK-1000 OVERVIEW:
The LSK-1000 limit switch kit is a physical hard backup limit. The standard control unit supplied with our AZ or EL
has "Electronic Limits", but the LSK-1000 limit switch kit, has been designed as a physical backup system in
the event of a control unit failure. The factory has pre-installed the LSK-1000 limit switch kit into the AZ and EL
units for you. Typically the LSK-1000 limit switches only need to be setup once, but can be
necessary.
LSK-1000 MANUAL LIMIT SWITCH PRE-TEST:
Remove one half of the black enclosure from the
positioner unit that DOES NOT have cord grips or
wires running into it. You will see the limit switches
(A,B) the limit arm (C), and limit screw (D) as
tured to the right. We have not installed the limit
screw due to unknown customer orientation. Move
the supplied RC2800PRKX2SU control unit near the
positioner for proper limit switch testing. With the
positioner wired to the control unit, turn the control unit
on. Be sure to test the proper direction of each
positioner before moving forward. Once you have
determined the correct direction of rotation from the
control units' "Control Buttons," determine which limit
switch will be activated by the rotation of the main
gear and limit screw. Press a known direction using
the "Control Buttons," and manually activate the limit
switch. At this point the positioner should stop it's
travel. Continue holding the limit switch and reverse
the direction using the "Control Buttons." The motor
should moved away from the engaged limit switch.
This confirms proper wiring and operation of the limit
switch. Repeat this procedure for the other direction
and limit switch. We suggest, completing each axis
(ie Azimuth and Elevation) prior to moving onto the
final setup.
FINAL SETUP OF THE LIMIT SET SCREWS:
We have included (2) limit screws, one for each limit switch. The limit screws can be setup at any position based
upon the orientation of your choice. On Azimuth and Elevation use the supplied 8-32 x 1/2" set screws and 5/64
allen wrench. DO NOT INSTALL AT THIS TIME. You can always make slight adjustments to the limit screw if
necessary. We have provided adjustment holes at every 5°. We suggest leaving the cover off of the unit until you
have completed your testing.
