Installation, Operation and Maintenance Instructions
spring return or Figure 2 for double acting
applications. Attach supply tubing to Port 1 and
use 3 and 5 for exhaust.
4. To prolong actuator life use only clean, dry plant
air. Lubricated air is not required, although it is
recommended, particularly for high cycle
applications.
Lubrication
All BUSwitch™ integrated spool valves are pre-
lubricated and will operate dry (with no additional
lubrication). The use of lubricated air will not
interfere with the functioning of the BUSwitch™. If
air lubrication is used, the oils listed below are
popular, easily obtainable, fluids that are
recommended for use with the BUSwitch

integrated spool valve: Gulf Harmony 47, Mobil DTE
Medium, Shell Tellus 29, Texaco Rondo B, Sohivis
47 and Sunnis 921. Many other lubricants are
acceptable providing they do not contain detergents
that will attack Buna N or Viton Seals.
Electrical Connections
CAUTION
To prevent ignition of hazardous atmospheres,
keep cover bolts tight while circuits are live.
Disconnect supply circuit before opening.
Entry into the BUSwitch™ integrated solenoid
housing is made through three ½” NPT conduit
entries. UltraSwitch enclosures feature two entries:
¾” NPT for XL and PL series and ½” NPT for GL
series. Figure 3 provides terminal locations on the
XA0244 interface card.
Connection of the data cable is made to connector
P3 - observing polarity. Incorrect polarity will not
damage the electronics, but it will prevent
communication. Caution: make sure power is
turned off when making electrical connection.
For hazardous locations, Underwriters Laboratories
(UL) and the National Electric Code (NEC) require
an approved sealing fitting within eighteen inches of
the switch enclosure.
