Limitorque UEX FCD LMENIM1205-03-AQ – 05/15
2 Safety
2.1 Safety Precautions
cc WARNING: Read this Installation and Maintenance Manual carefully and completely before attempting to install, operate, or troubleshoot the Limitorque L120 actuator.
cc WARNING: Be aware of electrical hazards. Turn off incoming power before working on the actuator and before opening the switch compartment.
cc WARNING: Potential HIGH-PRESSURE vessel – Be aware of high-pressure hazards associated with the attached valve or other actuated device when installing or performing maintenance on your L120 actuator. Do not remove the actuator mounting bolts when the actuator is mounted on a rising stem valve unless the valve is in the FULLY OPEN position and there is NO pressure in the line.
cc WARNING: Do not manually operate the actuator with devices other than installed Handwheel and Declutch Lever. Using force beyond the ratings of the unit and/or using additive force devices such as cheater bars, wheel wrenches, pipe wrenches, or other devices on the actuator Handwheel or Declutch Lever may cause serious personal injury and/or damage to the actuator or valve.
cc WARNING: Do not work on the actuator while it is mounted on a torque-seated valve.

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15
2.2 Safety Practices
The following checks should be performed to maintain safe operation of the L120 actuator.
•Mount motors on a horizontal plane, if possible.
•Keep the switch compartment clean and dry.
•Keep the valve stem clean and lubricated.
•Set up periodic operating schedule for infrequently used valves.
•Use a protective stem cover. Check valve stem travel and clearance before mounting covers on rising stem valves.
•Verify all actuator wiring is in accordance with the applicable wiring diagram, national and local codes, and Table 2.1.

3 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.
aa 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:
|
aa CAUTION: A torque switch limiter plate is provided on most actuators. |
||
8 |
• |
Removal or modification of the torque switch limiter plate will void the actuator warranty. |
|
• |
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.

1.Place the actuator in manual mode.
2.Remove the load from the wormshaft spring pack.
3.Note the open and close torque switch settings prior to reinstalling the torque switch.
4.Loosen Screws (A) and position both Pointers (B) at the #1 setting, tighten Screw (A). In this position the index marks should be aligned.

Limitorque UEX FCD LMENIM1205-03-AQ – 05/15
5.Loosen balancing screws and install the torque switch. The base of the torque switch should be flush against the compartment and the hole for the mounting screw should be aligned.
6.Install the mounting screw.
7.Tighten the balancing screws.
aa CAUTION: The balancing screws should not be touched except during the balancing procedure.
The switch is now balanced and ready for the pointers to be returned to their original settings.
3.3 Geared Limit Switch
aa 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.
3.3.1 Setting Limit Switch
Set the limit switch as follows. All item letters and piece numbers refer to Figure 3.2.
NOTE: See chart below for maximum number of drive sleeve turns for each unit size. The Intermediate
Shaft (B), shown in Figure 3.2, may take a considerable number of turns before rotor trip occurs.

3.3.2 Setting Procedure (Refer to Figure 3.2)
1.Open the Controls Compartment Cover (refer to Figure 5.5).
2.Put the actuator into manual operation. Use the handwheel to operate the valve in the “open” direction. While operating the valve, note the direction of the Intermediate Shaft (B) corresponding to the rotor or rotors to be set.
3. When the valve is fully open, close it one turn of the handwheel to allow for coast of moving parts |
11 |
or refer to the valve manufacturer setting requirements. |
|
4. Push in the Setting Rod (A) and turn one-quarter turn. The rod will latch in this depressed position.
flowserve.com
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.
aa 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.

3.3.3 Combination of Contacts (Refer to Figure 3.2)
The rotor segments can be separated and rotated through 90 degrees to give various combinations of normally open or normally closed contacts to each rotor.
1. Remove Nuts (piece 8) and Fillister Head Machine Screws (piece 5, for a total of two fasteners on each side of the switch).
2. Remove complete contact assembly from the back plate.
3. Rearrange cams on the camshaft to produce the required combination of contacts.
4. Replace contact assembly on back-plate (ensuring that the registers fit correctly) and secure with the machine screw and nuts.
12 5. Set limits according to the procedure above.
NOTE: For mechanical operation and maintenance of the L120 actuators, please see section 5 and 6 of LMENIM1201.
Limitorque UEX FCD LMENIM1205-03-AQ – 05/15
4 Removal of the UEC-3
