Section 1: Introduction
1.1 DO
1. DO follow proper storage procedures. Improper storage will void warranty.
2. DANGER: DO check for proper motor rotation. If valve goes wrong direction
when button is pushed, you have no torque or limit protection.
3-Phase incoming power voltage must have 2 wires reversed.
3. DO read and follow procedures before attempting to energize actuator.
4. DO cut off electric power before opening switch compartment.
5. DO install relief vent in highest point of gearbox.
6. DO use valve stem covers of sufcient length.
7. DO clean electrical enclosure ange thoroughly & lightly grease before closing.
8. DO secure electrical enclosure bolts (10-12 ft-lbs).
9. DO follow an annual maintenance procedure.
10. DO use caution when working on, with, or around valves and actuators.
You can be dealing with high pressures, forces, voltages and ammable media.

1.2 DON'T
1. Don’t Start-up without reading this manual.
2. Don’t stack actuators.
3. Don’t store actuator on the ground unprotected.
4. Don’t lift the unit by clutch lever or handwheel.
5. Don’t lift a valve assembly by electrical actuator.
6. Don’t operate electrically without rst checking proper phase rotation, torque
and position limit switch adjustments (follow instructions on pgs 2, 4 and 5).
7. Don’t plug actuator motor by starting and stopping repeatedly to move a too
stiff valve. Check for cause.
8. Don’t jumper torque switches except as recommended by Wiring Diagram or
Valve Manufacturer.
9. Don’t use oversize thermal motor overloads to eliminate tripping problem.
Find cause and correct.
10. Don’t use a cheater to force the handwheel. You can damage gearing and shafts.
Find cause and correct.
11. Don’t torque seat valve, sluice gate or damper unless the valve manufacturer
recommends.

1.3 Lubrication
Bettis Actuators are factory lled with a high quality lubricant carefully selected to insure
actuator performance under specied operating conditions. Refer to Bettis JOB SPEC
SHEET to identify the lubricant provided. Normal operation may not require lubricant
replacement.
1.4 Maintenance
At least once a year a check should be made of your Bettis actuator.
a. Disconnect all electrical power to actuator.
b. Open electrical enclosure. Inspect & tighten all electrical connections.
c. Visually inspect for any electrical or mechanical damage.
Replace worn or damaged components.
d. Check lubrication consistency and level. Fill or replace if required.
Section 1: Introduction

1.5 Pressure Relief
During operation of electric actuator, the gear temperature increase in combination with
variations of outdoor temperature will cause a small pressure build-up within actuator gear
box. Bettis furnishes Pressure Relief Vent Fitting Part No. 83385. Placement on Actuator
can be determined only after eld location and position of valve has been determined.
Select the highest 1/2 NPT vent location on actuator gear box; remove 1/2 NPT plug and
replace with 83385. The possible locations of vent are shown on Bettis Outline Drawing.

1.6 Short Term Storage
(Stored at Job Site less than one year from shipment)
1. Actuator should be stored with motor shaft in horizontal position and electrical
enclosure in either the horizontal or vertical position.

2. Actuator should be stored indoors free from job site dirt, mud, moisture and
temperature changes.
3. If indoor storage is not possible, the actuator must be stored off the ground above
possible water or snow level. Remove M2CP and store with other electrical and
electronic equipment in protected warehouse. If M2CP is not removed, Space
heater MUST be energized to protect electrical controls.
4. Bettis supplies NPT plugs in each conduit entry. Do not remove until electrical
hook-up. The customer conduit should be routed to enter electrical enclosure
at 1-1/2 (1.50) NPT located at lowest point, so condensation does not drain into
enclosure and damage parts.
5. Cover units loosely with a plastic sheet. This serves as partial protection from rain.
1.7 Long Term Storage
(Stored more than one year from shipment)
1. Store indoors or M2CP should be removed and stored in a protected area. Follow
procedures of short term storage.

WARNING
Failure to store actuator properly ill void warranty of electical & electronic components.

Section 2: M2CP Electical Hook Up
Remove PWR and TBM covers to expose terminals for customer wiring. Bettis Modular
Control Package (M2CP) is available congured in many combinations of electrical and
electronic parts. Refer to WIRING DIAGRAM and Bettis JOB SPEC SHEET for components
provided by Bettis. Connect control wires to TBM and Power (motor) Voltage to PWR
terminals. If optional M2CP mounted circuit breaker was specied, connect power voltage
leads to circuit breaker. Bettis terminal blocks are furnished with wire binding screw
connectors with rising captive plates, allowing eld connection by several methods: 1) strip
and connect bare wire, 2) strip and install wire ferrule, 3) strip and install crimp-on insulated
or non-insulated ring tongue or similar terminal. Circuit Breaker accepts 1) bare wire strip, or
2) wire ferrule.

Section 2: M2CP Electrical Hook Up
September 2018
2.1 Electrical Hook Up
Step 1. Move valve to mid-position by handwheel. This will allow sufcient time to
stop actuator in case of improper hook-up or reversed incoming power
voltage phases.
Step 2. Identify a means of removing power from actuator during check out.
Be sure no erroneous remote control signal can be received causing
actuator to energize.
Step 3. Energize Open control to check operation of contactor and pushbuttons.
Open controls must move valve in Open direction. If valve Closes, actuator
must be stopped and power input must be rewired.
CAUTION
If voltage is improperly phased, Torque and Position Limit Switches are not in circuit to
protect valve.

Step 4. Seal all eld conduit entries in accordance with National Electric Code.

September 2018
1. With actuator in place on valve, ensure proper ange mating and valve actuator
orientation.
2. Use a number 30 (.1285) drill bit to drill a hole 3/4 inch deep into the Drive Sleeve
assembly threads for the Locknut Lockpin (56) using groove in Stem Nut Locknut
as drill guide.
3. Install Locknut Lockpin (56) into drilled hole to prevent Stem Nut Locknut from
working loose and turning.
NOTE:
Install Locknut Lockpin (56) into drilled hole to prevent Stem Nut Locknut from working
loose and turning. When installing, the Locknut Lockpin - it should extend 1/4 inch above
the Drive Sleeve assembly to allow for future removal.
3.1.2 Stem Nut Installation (Multi-turn)
1. Unscrew Locknut (55) holding Bronze Stem Nut (54) and remove the Stem Nut and
Key (52).
2. Lubricate Stem and run Stem Nut down Stem to check acme thread t, then
remove Stem Nut and set aside.
