Extra Limit Switches
Installation Instructions for Series 75 Actuators
FCD WCAIM2063-00 (Part 16418)
Mounting
1. Remove cover of actuator to gain access to internals.
2. FOR 10-2375: Remove #4-40 slotted head screws, mount two
spacers (6) and extra switch (1) on top of standard switch.
Secure the switches with the same two #4-40 screws (2).
FOR 25/3075: Remove #4-40 slotted head screws, mount two
spacers (6) and extra switch (1) on top of standard switch.
Secure switches with longer screws provided in limit switch kit,
making sure to keep spacers (5) in place under standard switch.
3. Slip extra cam (3) onto actuator output shaft and position it so
that cam set screw faces terminal strip when cam is in contact
with limit switch to give desired function. Align cam with switch
lever. Cam lobe must approach switch lever from lever pivot end
and not from free end. See top view below.
Setting
1. Bring actuator into position desired to actuate extra switch. Turn
extra cam in direction of normal travel until switch just throws.
2. Advance cam in same direction by 1¾ and secure cam by tight-
ening the set screw (4).
To add a fourth switch (not shown), add the spacers and switch
to the one remaining position. Add the fourth cam (not shown)
and position it as described in paragraph 3 above. Follow setting
instructions above.
Wiring
Refer to wiring diagrams in this instruction sheet for making electri-
cal connections. A wiring label is also included with kit, which is to
be attached to inside of actuator cover.
Notes
All wiring to terminal strip should be inserted only to midpoint of
terminal strip. Terminal strip space is limited. If necessary, M1/M2
switch wiring can be tagged and spliced to external wiring. Tags
should indicate common, N.O. and N.C. wire connections.
