WARNING
PERSONAL INJURY
• Where possible, install these switches with the
conduit opening pointed down to drain moisture away
from switch.
• Do not install switch at the low point of a conduit run.
• Install a fitting into the conduit opening that provides
strain relief to the wires/cable, as well as sealing
against contaminants found in the application.
• In applications where fluids or moisture may be
present, seal the fitting threads with a product such
as Teflon tape or pipe dope.
Failure to comply with these instructions could result in
death or serious injury.
GENERAL INFORMATION
1. Refer to page 2 for specifications.
2. Rotate switch head to desired position
(90° increments). Review adjusting instructions
below.
3. Mount switch using two M4 or #8 screws (not
included). Torque screws to mounting surface
4,9 N m to 5,9 N m [43.4 in lb to 52.2 in lb].
4. All Normally Closed (NC) contacts are Direct
Opening.
ADJUSTMENT INSTRUCTIONS
To give flexibility in application, the user can perform the
adjustments described below in any order before wiring
the unit.
ACTUATOR HEAD POSITIONING
The actuator head may be positioned in any of four
directions.
1. Remove the four head retaining screws while
holding actuator head in place.
2. To prevent actuator spring loss, remove head slowly
to relieve spring tension prior to removal.
3. Rotate actuator head to desired position.
4. Position the large diameter end of the actuator
spring over the actuator. Place retaining screws
through gasket material and position head over
screw holes in desired position.
5. Securely tighten the screws to 0,2 N m [1.7 in lb] of
torque.
POSITIONING LEVER
The lever on rotary actuated units is adjustable to any of
the segmented positions 360° around the shaft;
however, the degree of rotation is dependant on head
position and direction of roller.
1. Loosen the lever retaining screw with a Phillips head
screwdriver.
2. Remove lever.
3. Reposition lever to desired location.
4. Securely tighten screw.
REVERSING THE ROLLER LEVER
The roller arm may be reversed to face the roller to the
inside or outside of the arm.
ADJUSTABLE LENGTH LEVERS
1. Loosen the lever’s adjustment screw using a Phillips
head screwdriver.
2. Adjust to desired length.
3. Securely tighten adjustment screw to
1.0 N m [8.85 in lb] of torque.
TOP ROLLER PLUNGER
Switches with top roller plunger must be mounted with
plunger in desired position. Actuating device must not
exceed over travel distance.
WIRING
1. Remove front cover plate screw.
2. Contact block area by terminal screw is labeled for
NO (Normally Open) and NC (Normally Closed)
contacts.
3. Connect stranded wire (0,75 mm2 - 2,5 mm2,
18 AWG-14 AWG) or solid wire (0,75 mm2 - 1,5 mm2,
18 AWG-16 AWG) to desired connector terminals.
Use 90 °C [194 °F] rated wire when ambient
temperature is to exceed 75 °C [158 °F]:
• Torque switch terminal screws to
0,8 N m to 1,0 N m [7.1 in lb to 8.9 in lb]
4. Securely tighten cover screw to 0,5 N m [4.4 in lb] of
torque.
