4.3.1.1 If present, the switch package must be

removed.

4.3.1.2 Release any air pressure in bottom

cover.

4.3.1.3 Remove clear plastic cap.

4.3.1.4 Use a wrench to turn the adjusting

bushing counter clockwise to close the
valve (record the number of turns).
Turn the adjusting bushing clockwise
the same number of turns to return
valve to open position.

4.3.1.5 Tighten Travel Stop nuts and assemble

plastic cap.

SWITCH PACK 2.0

(The switch package is not autoclavable,
maximum temperature is 150˚ F 65.5˚C)
(Switches and Positioners cannot be used
together)

Retrofit - The switch package as received from
the factory is pre-set, only minimal adjustment
is required to adapt to the actuator.

5.1 Field Mounting (1/4” through 2”, DIN 8 - 50, 3” &

4”, DIN 80 & 100, Series 33)

5.1.1 Remove the four(4) stainless steel screws on

the actuator top cover. Place the valve in the
open position.

5.1.2 Remove the plastic plug from the indicating

spindle.

5.1.3 Thread the switch indicating spindle into the

valve indicating spindle. Use Blue Loctite #242.

5.1.4 Mount the adapter, insure that both O-Rings

are on the adapter and lubricated with Dow
111. The correct torque is 5 in-lbs (.656 Joules).

5.1.5 Slide the switch sub assembly down over the

adapter, position the conduit entrances in the
location most desirable, (45˚ increments), press
down and tighten the set screw located on the
side of the lower housing to lock the unit in
place. The set screw torque should not exceed
5 in-lbs (.656 Joules).

5.1.6 Holding the lower housing stationary, unscrew

the top switch package cover and wire to the
terminal strip (Reference factory wiring decal).
Verify the switches operate correctly by cycling
the valve, see 5.3 for switch adjusting proce-
dure. Screw the switch package cover on,
insure the O-Ring remains in the groove.

5.2 Field Mounting

(3” and 4” Series 47, DIN 80 and 100)

5.2.1 Remove the clear plastic cap from the actuator.

5.2.2 Thread the switch indicating spindle into the

valve indicating spindle. Use Blue Loctite #242.

5.2.3 Thread on the adapter, insure that the O-Ring

is in place at the base of the adapter.

5.2.4 Slide the switch sub assembly down over the

5.2.5 Holding the lower housing stationary unscrew

5.3 Setting Switches

(Switches are identified with decal)

5.3.1 Remove top switch package cover.

5.3.2 Place valve in full open position.

5.3.3 Connect test device to terminal strip on con-

nections identified for SW (open) switch. The
switch type, inductive proximity versus dry con-
tact mechanical, determines the type of test
device required. Contact switches use a tradi-
tional volt meter with resistance capability to
verify continuity, inductive proximity switches
cannot use this method. Proximity switches
require an inductive proximity tester, such as
Pepperl+Fuch’s model #1-1305, which supplies
the proper load and supply voltage to the
switch. Inductive proximity switches must be
energized with the correct load and supply
voltage to sense the target.

WARNING: DO NOT SHORT THE INDUCTIVE
PROXIMITY SWITCH BY DIRECTLY CONNECT-
ING A POWER SUPPLY, IRREPARABLE AND
IMMEDIATE DAMAGE CAN OCCUR TO THE
SWITCH.

5.3.4 Loosen the two (2) screws on the open switch

slightly.

5.3.5 Use the adjusting screw accessible from the top

to move the switch up or down the bracket to
the optimum position. (Two turns past the trig-
ger location is recommended.)

5.3.6 Tighten the two (2) screws on the switch.

5.3.7 Place the valve in the full closed position.

5.3.8 Repeat the above steps for the SW (closed)

switch.

5.3.9 Replace the top switch package cover.

SWITCH PACK 2.5

(The switch package is not autoclavable,
maximum temperature is 150˚F, 65.5˚C)
(Switches and Positioners cannot be used
together)
