Section 1: Important Notes
1.1 User Safety
Safety notices in this manual detail precautions the user must take to reduce the risk of
personal injury and damage to the equipment. The user must read these instructions in
their entirety. Failure to observe these safety notices could result in serious bodily injury,
damage to the equipment, void of the warranty, or operational difculty.
Safety notices are presented as follows:
WARNING:
Alerts user of potential danger; failure to follow the warning notice could result in serious
personal injury or death.
CAUTION:
Identies precautions the user must take to avoid personal injury or equipment damage.
NOTE:
Highlights information critical to the user’s understanding of the TEC2 valve actuator
installation or operation.
1.2 Purpose
This installation and operation manual explains how to install, operate, and maintain the
TEC2 valve actuator.
TEC2 actuators are intended for automating part-turn and multi-turn valves within the
specied torque ranges for given model.
WARNING:
Read this manual in its entirety before installing, operating, or performing
maintenance on the TEC2 valve actuator.
Use caution when working on, with, or around valves and actuators.
High pressures, forces, voltages, and flammable media can be present.
Failure to follow instructions for proper electrical wiring, storage, setup, and
maintenance may cause serious injury, damage equipment, or void warranty.
Installation, Operation and Maintenance should only be performed by
qualified personnel.

Section 1: Important Notes
Important Notes
1.3 Storage Procedures
If your actuator cannot be immediately installed, the following procedures are to be
followed. This will ensure optimum performance from your TEC2 actuator. Failure to
comply with recommended procedures could lead to actuator malfunction and will void
the warranty. For storage procedures exceeding one year, contact your local Emerson
Representative for recommendations.
The TEC2 actuator is a double-sealed and inherently weatherproof unit when shipped
from the factory, providing that all compartment covers and cable entry plugs remain
intact. The actuator should be immediately stored in a clean, dry warehouse, free from
vibration and rapid temperature changes, until it can be installed and energized.
If the actuator must be stored outside, it should be stored off of the ground at an
elevation sufcient to prevent it from being immersed in water or buried in snow,
and covered to prevent damage from site debris.
If not attached to a valve, the preferred orientation is with the motor and electrical
compartment horizontal.
If the actuator is mounted on a valve and the valve stem protrudes from the unit,
a suitable stem protector must be installed to prevent drive-sleeve corrosion.

Quick Start
Section 2: Quick Start
The Quick Start Section provides step-by-step instructions for initializing the TEC2
actuator. When these instructions are complete, the position limits will be set and the
actuator will be ready for normal operation.
NOTE:
The actuator has been congured as specied by the customer and no further changes
should be required. If full valve data was not provided, actuator will be shipped with
default conguration per Table 4.4, Default Configuration Settings, unless specic
conguration was requested.
WARNING:
Use caution when working on, with, or around valves and actuators.
High pressures, forces, voltages, and flammable media can be present.
WARNING:
Verify voltage rating on nameplate before connecting power.
2.1 Set Position Limits
1) Power actuator. The alarm message “SET LIMITS BEFORE OPERATING” will be
displayed. The alarm icon and the yellow LED will be ashing. Valve position will be
displayed as “EE%”.
2) The instruction is based on valve being in closed position. If valve is at "Open"
end of travel, you must move the valve in "Close" direction and set a dummy
close limit. Then move back to "Open" and set the open limit. Save the limits.
Proceed as follows to set the limits. See Section 5.5.3, Set Valve Travel Limits
for additional details.
A) Enter the “SETUP” mode.
1) Place the selector knob in the STOP position.
2) Rotate the control knob to YES, then NO, then YES, then NO in
rapid succession and then release. The Setup icon will be displayed
on the display module and “SETUP?” will be displayed on the
message center.
3) Rotate the control knob to YES. “SET LIMITS BEFORE
OPERATING” will be displayed on the message center.
4) Rotate the control knob to the LOCAL position. The message
“CLOSE VALVE THEN SELECT STOP” will be displayed.
B) Set close valve travel limit.

Section 3: Installation
Installation
1. Unscrew Locknut (piece #55) while holding Bronze Stem Nut (piece #54) or Steel
Bore and Key Bushing. Remove the Stem Nut and Key (piece #52).
2. Lubricate Stem. Run Stem Nut (piece #54) down Stem to verify Acme thread t.
Remove Stem Nut (piece #54) and set aside.
3. Model 3000-8000 may include thrust base assemblies. See Appendix for instructions.
3.2 Mechanical Installation onto the Valve
1. Lower actuator over Stem onto valve ange.
2. Insert the screws through the valve ange into the actuator and engage at least
one full screw diameter deep into the bottom base.
3. Tighten to a preload.
See Appendix for common bolt tightening torques.
NOTE:
Mounting screws are provided only if Emerson supplied the adapter. Verify screws are
through the adapter; engage a minimum of one screw diameter deep into the actuator
base.
4. Screw the Stem Nut (piece #54) onto the Stem until it enters the Drive Sleeve.
5. Place Key (piece #52) in line with the Drive Sleeve Keyway. Insert Key (piece #52).
6. Turn the handwheel in the Open direction to pull the Stem Nut (piece #54) into
the Drive Sleeve until it bottoms out.
NOTE:
Valve will begin to open.
7. Place the Locknut (piece #55) over the Valve Stem. Screw the Locknut
(piece #55) rmly into place against the top of the Stem Nut (piece #54)
using a drift to tighten.
8. Use a number 30 (0.1285) drill bit: drill a hole 3/4 inch (19mm) deep into the
Drive Sleeve assembly threads for the Locknut Lockpin (piece #56).
Use the groove in the Stem Nut Locknut threads as a guide.
9. Install Locknut Lockpin (piece #56) into drilled hole to prevent the
Stem Nut Locknut (piece #55) from working loose and turning.
NOTE:
When installing, the Locknut Lockpin (piece #56) should extend 1/4 inch (6mm) inch
above the Drive Sleeve assembly to allow for easy removal.
CAUTION:
Locknut must be screwed very tightly against stem nut.

3.3 Electrical Connections
3.3.1 Remove Separate Terminal Chamber (STC) Cover
WARNING: BEWARE OF MULTIPLE POWER SOURCES
Verify power is disconnected before removing STC Cover.
Multiple power sources may exist under the cover.
NOTE:
Valve actuator requires a circuit breaker within the line of sight, sized for the
motor currently specied on the nameplate.
See Appendix Section A.7, for the circuit breaker options.
Remove cover with a strap wrench, drift, or pinch bar by rotating the
cover counterclockwise.

3.3.2 Sealing Cable/Conduit Entries
Seal the cable and conduit entries in accordance with the National Electric Code
or your country standard and applicable local codes. All conduit entries should be
sealed against the site environment. All unused conduit entries must be sealed
with threaded metal plugs.
3.3.3 Recommended Terminal Connections
The TEC2 terminal block connectors are wire binding screw connectors with rising
captive plates. Connections can be made one of three ways:
• Strip and connect bare wire.
• Strip and install wire ferrule.
• Strip and install crimp-on insulated or non-insulated ring or fork-tongue
connectors for either M3 control signal terminal block screws or M4 power
terminal screws.
1. Loosen terminal block connectors L1, L2, L3 and GND screws with a
common or Phillips head screwdriver.
2. If bare wire is being used, strip insulation a maximum of 0.4 inch (10 mm).
3. Insert wire or wire lug under terminal block connector screw clamps
and tighten.
Figure 3-3 details power terminal size and length of bare wire strip. Figure 3-4
details control terminal size and length of bare wire strip.
