Bettis Modular Control Package (MCP) is available congured in thousands of possible
combinations of electrical and electronic parts. Refer to WIRING DIAGRAM and Bettis JOB
SPEC SHEET provided by Bettis with each actuator.
3.2 Electrical Hook Up
Step 1. Move valve to mid-position by handwheel. This will allow sufcient time to
stop actuator in case of improper hookup or reversed power phases.
Step 2. Identify a means of removing power from actuator during check out.
Step 3. Be sure no erroneous remote control signal can be received causing actuator
to energize.
Step 4. Energize Open control to check operation of contactor and push buttons.
Open controls must move valve in Open direction. If valve Closes, actuator
must be stopped and the power leads reversed to correct voltage phasing or
improper eld wiring.
CAUTION
If voltage is improperly phased, Torque and Limit Switches are not in circuit to protect valve.
Step 5. Seal all eld conduit entries in accordance with National Electric Code
requirements

Section 4: Geared Rotary Limit Switch
Setting Instructions
4.1 Before making any switch setting:
1. Move valve to mid-position using handwheel.
2. Phase the power (motor) voltage and make sure that open contactor moves valve
Open and Close contactor moves valve Closed.
DANGER
Improper power voltage phasing eliminates protection of both geared limit switch and
torque switch, risking valve damage.
4.2 To set Open Limit Switch (LSO)
1. Open valve — During handwheel operation note direction of rotation of LSO
Adjusting Shaft (1) Fig. 7. After the valve is fully Open, Close it three handwheel
turns to allow for coast.

12 Geared Rotary Limit Switch Setting Instructions
IMPORTANT:
To insure that spur gears have engaged properly, lightly jiggle all adjusting shafts (1) with
screwdriver back and forth; proper engagement has been made if all shafts will not turn. If
all shafts do not lock in place, the limit switch setting will be lost when valve is moved.
NOTE:
Since many turns may be required to set limit switches, it may be convenient to use a
reversible variable speed drill to rotate Adjusting Shaft (1) instead of screwdriver.
Limit Switch Gear Box is gear driven by the gear limit pinion assembly. The gear limit
pinion is driven by the actuator output worm and is always mechanucally in step with valve
position. N is the total number of turns of spring loaded gear limit pinion assembly for full
valve stroke.
4.3 To set Close Lmit Switch (LSC)
1. Close valve, using handwheel. During handwheel operation note direction of LSC
adjusting shaft. After valve is fully Closed, Open it several handwheel turns to allow
for coasting.
2. Repeat steps 2 through 5 of LSO setting instructions with screwdriver in LSC cavity.
4.4 To set Intermediate Switch (LSA or LSB)
1. Open Valve to desired position, then repeat steps 2 through 5 of LSO.
4.5 Torque Seated Valves
If valve is a torque seating valve, and the geared limit contacts are used for pilot light
indication only, the LSC switch should be set several handwheel turns ahead of torque
switch contact action. This gives proper valve position Pilot Lamp indication in spite of
minor position variations which might occur due to torque seating.

13Torque Switch TSC and TSO Setting
Section 5: Torque Switch TSC and TSO Setting
5.1 Description
Bettis Torque Switch senses mechanical over load in Close (TSC) or Open (TSO) direction.
Worm is supported with bi-directional disc spring stack. As worm and gear torque
increases, the worm moves axially against spring allowing Torque Limit Gear Assembly to
rotate Part No. 1050, Torque Switch.
Part Number 1050 has N.C. contact for (LSC) and (LSO). Part number 1050-1, in addition to
N.C. also provides a N.O. contact.

5.2 Adjust with Screwdriver
The only tool required for torque adjustment is a screwdriver. To change setting:
push screwdriver down about 1/16" and rotate.
Figure 11
5.3 Approximate Torque Spring Chart
See Bettis supplied specication sheet for approximate torque spring settings.
Manufacturing tolerances affect the torque at a specic torque switch setting.
If exact torque curve is required; at an additional charge, Bettis will test and plot curve for
specic actuator.
5.4 Torque Switch Calibration
5.4.1 To set CLOSE Torque Switch (TSC)
a. Close valve using handwheel. Set valve to the desired torque. Observe
rotating dial for number that corresponds to desired Valve Close Torque.
b. Insert screwdriver in slot of TSC dial. Press down to disengage and turn
the arrow to the setting determined in a). Release at this point and it will
re-engage and remain set automatically.
c. Back the valve away from Close position and reseat by handwheel to verify
the trip point is at desired setting. The trip point of switch is distinctive as
it makes or breaks contact.

15Torque Switch TSC and TSO Setting
DANGER
Reverse voltage phasing removes torque switch protection from reversing contractor valve
damage could occur.
If phasing has not been checked, do so before proceeding. Back valve away from Close
position with handwheel and test electrically, using Close controls. Readjust as required.
5.4.2 To Set OPEN Torque Switch (TSO)
a. Follow the procedure as for the TSC in open position.
5.5 Switch Rotation Limit
Torque Switch adjustment rotation may be limited. Remove switch cover to expose anti-
rotation pins at Open and Close positions. Remove pin from position 10 and insert into
desired number. Torque may be roughly estimated from Table on Bettis Spec Sheet or
determined by production or actual eld test.
