Honeywell Limit switch 125 Vac 10 A Tappet momentary 2LS1-4PG IP67 1 pc(s) 2LS1-4PG 사용자 설명서

Operation in clockwise, counterclockwise or both
directions of the lever arm is possible. As factory

assembled, the switch is actuated in both directions.

To convert the switch to one direction actuation,
remove the actuator head and rotate the step plunger
90° clockwise or counterclockwise. When the switch
is adjusted for actuation in one direction only the
arm may be moved to the full overtravel position in
the opposite direction without damaging the mechan-

ism.

If the actuator head is removed and replaced, read-
justment for operating characteristics may be nec-
essary. See Adjusting Operating Characteristics.

When replacement of the contact block is necessary
or if the actuator head is removed and replaced, re-
adjustment may be required to duplicate the operating
point as originally provided in the factory assembled
switch.  This adjustment is made after the contact

block has been secured to the housing and with the

external lever arm or in-line plunger in the free
position. Using a 3/16-inch wrench, turn the adjust-
ing screw two turns clockwise (two wrenches are
needed for top in-!ine plunger switches). Insert a
.045 to .049 inch feeler gauge between adjusting
screw and internal switch plunger. Turn adjusting
screw counter-clockwise until contact block operates.
See "Handy Adjusting Tool Set" 15PA53.

Hold the actuating plunger in fully depressed position
and with a 3/16-inch wrench, turn the adjusting screw
counterclockwise until the switch "clicks". Then
continue to turn the screw another ¾ turn to provide
the necessary overtravel.

CAUTION: Be certain not to turn the adjusting screw
more than ¾ turn beyond the operating point. It could
exceed the overtravel of the basic switch and cause

permanent damage to the contact block.
Adjusting Yoke Type Actuated "LS" Switches

Remove the switch cover plate (or entire switch in
the 206LS1 "Plug-in" design) to expose the internal
actuating plunger and the contact block. Using the
screwdriver slot on the end of the shaft as a guide,
adjust internal plunger set screw so that the basic
switch operates and releases at approximately equal
angles past the vertical line on the screwdriver slot.
Adjust in both the counterclockwise and the clock-
wise directions.

Be certain not to turn

the adjusting screw
too far out, so that it

would exceed the over-

travel of the contact

block and cause per-
manent damage to the
contact block.

INTERNAL PLUNGER SET SCREW

Adjusting instructions and figure below apply to
the short pretravel switches 1LS19, 1LS27, 1LS47,
1LS56, 1LS58, and 1LS59.
Using a 3/16-inch wrench, turn adjusting screw two
turns to the right. Insert .008-inch feeler gage be-
tween adjusting screw and top lever. Turn adjusting
screw to the left until basic switch clicks.

Use two 3/16-inch open end wrenches to hold plunger
and turn adjusting screw two turns clockwise. Insert
a .025 to .030 inch feeler gage between adjusting
screw and button on contact block. Turn adjusting
screw counterclockwise until contact block operates.

Remove cover plate (or entire switch assembly of

"Plug-in" design) and remove the plastic contact
block. Turn internal plunger adjusting screw two full
turns to the right. Mount new block.
