Limit Switch & Torque Switch
Setting Procedures

3.1 Initial Actuator Preparation

Replace all molded plastic conduit and top protectors (installed for shipping purposes only) with pipe
plugs when installation wiring is complete.

3.2 Torque Switch

The torque switch is designed to protect the actuator in open and close directions.

a CAUTION: Disconnect all incoming power before opening limit switch compartment or working on

the torque switch.

• Do not use abrasive cloth to clean the contacts on the torque switch.

• Do not torque seat 90° operation valves nor run them against the stops. This may cause damage
to the valve.

NOTE: If the actuator has “torqued out,” release torque buildup by operating the actuator manually.

3.2.1 Setting Torque Switch

The torque switch was set at the factory according to customer-supplied information regarding neces­sary torque or thrust output that was provided at the time of the order. However, if the setting needs to
be adjusted, perform the following procedure:

a CAUTION: A torque switch limiter plate is provided on most actuators.

• Removal or modification of the torque switch limiter plate will void the actuator warranty.

8

• Do not exceed the setting indicated by this plate without contacting the Limitorque service
department.

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15

• Installing or adjusting the torque switch with the actuator in a loaded condition will result in a loss
of torque protection.

Item letters correspond to Figure 3.1.

1. Place the L120 actuator in manual mode.

2. Release the load on the wormshaft spring pack.

3. For open and close directions, loosen Screw (A) and move Pointer (B) to desired position. A higher
number indicates a high torque and/or thrust output.

4. Tighten Screw (A).

5. Operate the valve electrically to seat valve and to ensure tight shutoff.

6. Rebalance torque switch if required.

3.3 Geared Limit Switch

a CAUTION: The geared limit switch is not preset at the factory and must be adjusted after the

actuator has been mounted on associated equipment.

• Disconnect all incoming power to the actuator prior to opening the limit switch compartment and

adjusting the switch.

• Consult the relevant wiring diagram for limit switch contact development. All L120 units are

supplied with 16-contact limit switches - four switches on each of the four rotors. Two rotors are
used for end of travel indication. The remaining two rotors may be adjusted for any intermediate
point of travel.

• Do not use abrasive cloth to clean the contacts on the limit switch.

• Do not attempt to repair gearing in the limit switch. Replace entire gear frame assembly if

necessary.

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15

5. Refer to the applicable wiring diagram for contact development. The limit switch contact is closed
when the rotor is engaged with the plunger. If the rotor to be set has not turned 90 degrees to
operate the plunger, turn the intermediate shaft in the same direction as noted in Step 2 until the
rotor clearly trips the switches. This rotor is now set correctly.

6. Before moving the valve, depress and turn the Setting Rod (A) one-quarter turn to the spring
released position. Insert a screwdriver into the intermediate shafts to ensure that they will not move.

a CAUTION: Do not operate the valve when Setting Rod (A) is in a fully depressed position. Loss of

contact setting will occur and the setting rod will be damaged.

7. Operate the valve by handwheel to fully “close” position; reverse direction by one turn of the hand­wheel to allow for coast of moving parts or refer to the valve manufacturer setting requirements.

8. Set the other rotors by following Steps 4 through 6.

6.2 Local Control

The Control Panel includes a red Local/Stop/Remote selector switch (padlockable in all three positions;
a ¼" (6 mm) hasp is recommended) and a black Open/Close rotary switch (spring-return to center). The
Open and Close switches may be configured to allow either push-to-run (inching) control or maintained
control.

Local Indication

The Control Panel includes the following:

• 32-character graphical LCD

Displays valve position as “PERCENT OPEN” and the current actuator status.

• Red/Green LED Indicators – the color assignment for the red and green LEDs is reversible as
standard.

Red ON = Valve fully open

Red “BLINKING” = Valve opening

Green “BLINKING” = Valve closing

Green ON = Valve fully closed

• Yellow LED

Yellow ON = Actuator available for remote operation,

= Valve stopped in Intermediate position.

Yellow “BLINKING” = Monitor Relay de-energized, actuator not available for remote operation.

6.3 Remote Control Modes of Operation

The actuator may be controlled remotely by two, three or four wires.

• Four-Wire Control – Three momentary contacts. Valve can be opened, closed or stopped.

• Two-Wire Control – Single open or closed contact. Valve can be opened or closed, but not stopped in

mid-travel.

• Three-Wire Maintained – Two momentary contacts for self-maintained control. Valve can be opened
or closed but not stopped in mid-travel.

• Three-Wire Inching – Two “push-to-run” contacts. Valve can be opened, closed and stopped in
mid-travel.

Refer to Figure 15.4 for remote wiring connections.

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15

Remote Control Type

The actuator may be placed in digital only, modulation only, network only, or multi-command types.

• Digital (Discrete) Only Control Type – Only digital input commands are recognized and acted upon.
All other types of remote control commands are ignored.

• Analog (Modutronic) Only Control Type – Only Modutronic 4-20 mA commands are recognized and
acted upon. All other types of remote control commands are ignored.

• Network Only Control Type – Only network (DDC, Fieldbus, Profibus, Device Net) commands are
recognized and acted upon. All other types of remote control commands are ignored.

• Multi-control Mode Operation - there are three modes of remote control when remote mode is
configured for multi control: digital control, analog control, and network control. Digital and network
control operation is based on the last command received. Analog operation is initiated by either
toggling user input 2 (configure for CSE input) or breaking and reapplying the analog control.

Remote Control Signal Power

Power for remote control signals may be derived internally from the actuator or provided externally by
the user. Signals can range from 24 to 125 VAC or VDC.

External Power Supply

An external power supply in the range of 12 to 24 VDC may be provided by the user with the optional
UPS board.

Standard Internal Power Supply

The standard internal signal supply is 24 VDC. The 24 VDC supply offers a maximum loading of 5 W.
The 24 VDC supply, in conjunction with the opto-isolated digital inputs, allows control from remote volt­free contacts over long distances and simplifies the user’s control scheme. Standard control employs a
negative earth. Positive earth (negative switching) is available by wiring to the (+) positive common as
shown on the wiring diagrams.

6.4 Emergency Shutdown (ESD)

Up to three independent ESD signals may be applied, prioritized and configured for different actions
for the ESD event associated with each. Either of these ESD signals may be applied to the actuator
to override any existing command signal and send the valve to its preselected shutdown position,
providing the actuator is in Remote mode (default configuration for ESD is “Ignore, take no action”).
Any new command signal will be ignored until the ESD signal is removed. During setup, the actuator
may be configured to close, open, stop, take no action, or “move to a previously configured position” on
receipt of the ESD signal. The ESD action may also be configured to override any inhibit signal, the local
selector switch, the local stop switch, an overtorque condition, lost phase, or jammed valve protection.
Motor thermal protection may be bypassed for critical ESD applications in non-hazardous or special
service locations. Disabling the motor thermostat voids all third-party certifications, including Factory
Mutual and CSA.

24

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15

6.5 Remote External Interlocks/Inhibits

Three user-defined inputs are provided for the connection of remote contacts that will prevent motor­ized operation of the actuator. These are effective in both Remote and Local modes and may only be
overridden by a maintained ESD signal, if so configured (refer to Figure 15.1 for wiring connections).
For ESD connections, the user may select either a single common or isolated commons.

6.6 Absolute Position Encoder

An absolute position encoder, incorporated into the L120 actuators, is the same as the encoder used in the
MXa. It includes 18 phototransistors that are switched on and off by a gear/wheel mechanism.Valve position
is sensed by an 18-bit, optical, absolute position encoder with redundant position sensing circuits designed
for Built-In Self-Test (BIST).

Each of the position sensing circuits is redundant, facilitating BIST. The BIST feature discerns which
failures will signal a warning only and require a warning plus safe shutdown of the actuator. Open and
closed positions are stored in permanent, nonvolatile memory. The encoder measures valve position at
all times, including both motor and handwheel operation, with or without power present, and without the
use of a battery. The absolute encoder is capable of resolving ±7° of output shaft position and over 10,000
output drive rotations, however, in the L120, the encoder is limited to the maximum geared limit switch
travel. Refer to Table 3.1.

This design permits continuous monitoring of valve position during motor and handwheel operation. The
encoder is 100% repeatable and requires no backup power source for operation. The output is used to
control the open and closed valve position and measure and report valve position, as well as provide local
and remote position feedback.

The positioning accuracy is better than 99% for valves requiring 50 or more turns. For the maximum
actuator turns and resolution, see Table 3.1.

Figure 6.2 – Absolute Position Encoder

18-bit optical, redundant position
encoder provides continuous valve
position monitoring without battery
backup with Built-In Self-Test (BIST)
capabilities.

Protection Features

7.1 Autophase Protection and Correction

The phase rotation of the incoming three-phase supply is continuously monitored. In the event that field
wiring is reversed, UEX controls automatically correct to ensure the valve operates in the commanded
direction. In addition, the detector circuit monitors the presence of all three phases. If a phase is lost,
valve starting will be prevented and the user alerted via an LCD error message and Monitor Relay Alarm.

7.2 Jammed Valve Protection

If the actuator cannot overcome the required valve starting torque, a jammed valve condition occurs.
Jammed valve protection senses the lack of valve movement and initiates a brief reverse/forward cycle
to free the valve. If this is unsuccessful, further electrical operation is prevented and the monitor relay is
signaled.

7.3 Instantaneous Reversal Protection

The control logic incorporates a brief time delay (from 0.5 to 1.0 seconds) between motor reversals.
This reduces motor current surges and prolongs the life of the contactor. Note: It is not necessary to
switch to STOP before reversing the actuator.

7.4 Motor Thermal Protection

The motor is protected against overheating by a thermal OL in the motor enclosure. Thermal cutout
threshold is set for 120˚C (Class B). Options are available for other classifications.

26

a CAUTION: Confirm that motor thermals are rated no higher than 120°C for Explosionproof service.

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15

Optional Control Features

8.1 Modutronic

The Modutronic controller will alter valve position in proportion to an analog command signal. It
includes an automatic pulsing mode to reduce overshoot at the set point.

The following parameters may be easily set during the configuration of the unit:

• Proportional Band range from 2% to 100% (15% = default)

• Dead Band range from ± 1% to 50% (2% = default)

• Polarity 20 mA = OPEN (default) or 20 mA = CLOSE

• Action on loss of command signal OPEN, CLOSE, STOP (CLOSE = default), or Move-to a previously
configured position

• Delay after stop 0–60 seconds (0 = default)

• Command Signal

• 4–20 mA

• Input impedance - 150 ohms

Repeatability – The Modutronic is repeatable to within ±1 % for 60 seconds stroke time or longer,
and 2% for 30 to 60 seconds.. Repeatability is defined as encoder feedback position versus position
command. Overall valve and actuator system accuracy depends on many factors, including actuator
gearing backlash and valve/actuator coupling tolerance, and therefore cannot be defined by this
document.

Extrema Mode – If the command signal represents a position of 0–2% OPEN (nominal 4.00–4.32 mA)
or 98–100% OPEN (nominal 19.68–20.00 mA), then the UEX/L120 will move the valve directly to that
position, without pulsing.

Positioning Frequency – The standard frequency is suitable for a rate of 600 starts/hour for short
periods, typical of process start-up. Typical process control of ≤ 100 starts/hour.

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15

8.2 Analog Position Transmitter (APT)

The APT is an internally powered, non-contacting valve position transmitter. The isolated output signal
is proportional to the position of the valve and is available as 4–20 mA and/or 0-20 mA, 0-10 VDC, 2-10
VDC, 0-5 VDC, or 1-5 VDC.

The user may select the minimum signal to represent either the fully OPEN or the fully CLOSE position
of the valve during the setup procedure.

• Accuracy = 99% of full scale value (for Drive Sleeve Turns > 50)

• Non-Linearity = ± 1% of full scale value

• Impedance = 0–600 ohms (4–20 mA signal)

• Minimum external load = 1000 ohms (0–10 VDC signal)

8.3 Two-Speed Timer

A two-speed pulsing timer can be enabled to extend the operating time in the close and/or the open
directions. Pulsing may be applied from 0.5 (if precision is set to xxx.x%) to 99% of full valve travel or
to a small portion. The ON pulsing cycle is configurable from 0.5 to 20 seconds in 0.5 second incre­ments, and the OFF pulsing cycle is configurable from 1.0 to 200 seconds in 1 second increments. The
two-speed timer is especially effective where concerns of hydraulic shock exist.

28

8.4 Control Station (CSE)

The CSE is a separate control station designed for the operation of inaccessible actuators. It is available
with LEDs, Remote/Local and Open/Close selector switches. The CSE may be powered by the actuator
internal supply, provided wire resistance and other external loads do not limit the available signal power
presented to the UEX.

Network Communications

The UEX provides a comprehensive network option portfolio to the user. Network solutions are improved
for the user that has an L120 with UEC, with the addition of DeviceNet to complement Modbus,
Fieldbus H1, Profibus DP_V1 and Profibus PA. UEX provides the user with predictable, reliable, and safe
operation for years to come, in applications which are subject to the most rigorous requirements and
environmental extremes.

With each of the provided network protocols a user may configure the unit to move to a predefined
fail-safe position on loss of communication. Action on loss of command signal OPEN, CLOSE, STOP, or
MOVE-TO preconfigured position. The user may also configure the length of time communication must be
lost before the unit indicates communication loss and performs the communication loss action.

9.1 Modbus

Modbus™ provides the ability to control and monitor up to 250 actuators over a single twisted-pair
cable. The communication network employs Modbus
dant. Redundancy assures that any single break or short in the communication cable will not disable
any actuators. Each actuator has included an addressable field unit that communicates over the twisted
pair network and executes open, close, stop, ESD, and GO TO position commands. The field unit
also communicates all actuator status and alarm diagnostic messages over the same communication
network.

11.1 Actuator Status Contacts
(S1a, S1b, S2a, S2b)

Four latched contacts provide remote feedback of actuator status. Two (S1a, S2a) contacts may be
individually configured for normally open, normally closed, or blinker (continuous opening and closing
of the valve) operation and provide feedback of one of the functions listed below. Two other relays are
complementary.

• Closed • Motor overtemp

• Closing • Overtorque

• Mid-travel • Open torque switch

• Opening • Close torque switch

• Open • ESD signal

• Stopped • Open inhibit

• Valve moving • Close inhibit

• Local selected • Lost phase

• Local STOP/OFF • No analog signal

• Manual operation • Hardware failure

• Valve jammed • Network controlled

• Remote selected • CSE controlled

36

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15

Recommended settings are:

• S1a – Normally closed contact at valve fully CLOSE

• S1b – Normally closed contact at valve fully OPEN – Default position. See wiring diagram.

• S2a – Normally open contact at valve fully CLOSE

• S2b – Normally open contact at valve fully OPEN – Default position. See wiring diagram.

The standard contacts are rated for 2.0 A at 30 VDC and 0.5 A at 125 VAC.

11.2 Monitor Relay (RM)

The monitor relay provides immediate indication of problems that prevent remote valve operation. It has
a normally open contact and a normally closed contact (1 x SPDT contact) and is energized when the
three-phase supply is present and the actuator is in a normal/healthy state.

The relay will de-energize if any of the following events occur:

• Loss of one or more phases of the three-phase power supply

• Loss of internal control supply

• Jammed valve detected

• Motor overtemp is active (unless thermostat is configured to OFF)

During configuration, the following parameters may be added to the monitor relay function:

• Selector switch is in “Local” mode

• Selector switch is in “Stop” position

• Overtorque

• Inhibit signal active

• ESD signal active (The user can enable or disable “local” mode and “stop” position. Default is
enabled.)

The monitor relay resets when the faulty state is rectified. The standard contacts are rated for 5.0 A at
250 VAC, 30 VDC. The monitor relay can be disabled if the user chooses.

11.3 Exact End Position Indication

On torque-seated valves, the end-of-travel indication switch trips when the required torque is achieved
at the end of travel. This ensures that remote, self-latched signals will not be disconnected prematurely,
and that the valve will be tightly seated.

16.2 Network Wiring – Foundation Fieldbus H1

Please refer to LMENIM2330 for detailed installation instructions.

Limitorque’s F
for use on the H1 highway and uses a twisted-pair cable for connection to the highway.

The UEX FF field unit fits in the actuator in the sealed electrical housing. All adjustments to the UEX FF
settings may be made over the F

The UEX FF unit may command its actuator to open, stop, close, move to a set position, or perform an
emergency shutdown operation. Commands to the unit come over the network from the host system,
which may be a PC, Distributed Control System (DCS), Programmable Logic Controller (PLC), or some
other microprocessor-based device. Commands may also be generated in another network actuator or
device and transmitted over fieldbus using peer-to-peer, publisher/subscriber communication.

A fieldbus device is an intelligent device within the actuator that can send multiple variables to the
control system over a high-resolution and distortion-free digital communication network. The device
provides control and self-test capabilities, which allow abnormal conditions to be easily and immediately
identified before an unplanned shutdown.

Additional features and benefits are:

• Reduces cost of wiring and installation – existing wiring and multi-drop connections can be used.

• Interoperable devices – devices from different suppliers can communicate with one another on the
same network.

A typical UEX FF system is shown in Figure 16.2.

Please refer to LMENIM2336 for detailed installation instructions.

Profibus is based on RS 485 communication. The standard EN 50170 specifies the cable for use with
Profibus DP and PA. Table 16.1 shows specifications that need to be fulfilled by the Profibus cable.

When there is a need for more flexiblity (bending) and higher environmental resistance, a cable with
stranded wire for the Profibus line and special jackets shall be used.

Limitorque recommends the use of:

• Belden 3079A Specifications, 22 AWG, shielded, solid two conductor

Please refer to LMENIM2328 for detailed installation instructions.

DeviceNet is a CAN - based protocol that uses 5 wires including a shield. Two of the conductors are
used for 24V DC power & up to 8 amps (4 amps for NEC Class 2) may be passed along the hi-way from
a suitable power source. Two conductors are used for the CAN bus signals, CAN_H and CAN_L, which
are usually smaller in diameter. Limitorque recommends Belden cable for connecting to a DeviceNet
network. The specifications for thick and thin cable (per site requirements) are as follows:
