Adjusting Limit Switches
UltraSwitch™ enclosures feature quick-set cams which
are used to trip the limit switches. These cams are easily
adjusted without tools. Caution: disconnect power before
removing cover when installed in hazardous locations.
Remove cover and set aside. Rotate actuator/valve to full
clockwise (CW) position. Adjust cam(s) associated with CW
as follows:
1. Push or pull cam against spring to disengage it
from splines.
2. Rotate cam CW breaking contact with switch
(or moving magnet away from switch).
3. Continue rotating cam CW just until switch trips.
4. Release cam and reengage it with splines.
Rotate actuator/valve to full counterclockwise (CCW) posi-
tion. Adjust cam(s) associated with CCW as described in
steps 1 through 4, except rotate cam(s) CCW.
Note: factory setting is top switch = CW (closed), second
switch = CCW (open), third switch = CW, and fourth
switch = CCW.
Adjusting Pharos™ Position Indicator
Pharos visual indicators are easily adjusted to match
the dome’s clear windows to the rotor’s red and green
quadrants. Simply pry upward under dome “flange” with a
large, flat-bladed screwdriver to remove. Make sure o-ring
is fully seated against the flat dome sealing surface, not
in the dome retaining groove, as shown. Then install dome
in a tilted fashion, engaging one of the dome locking tabs
in the dome retaining groove. Make sure dome windows
line up with rotor quadrants. Finally, using a rubber mallet,
strike dome as shown to engage all locking tabs.
