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.

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.

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.
