1 Important Notes

• Please read this manual in its entirety before attempting to install or operate your QX actuator. A full understanding

of the installation and operation options will assist you in installing the actuator in the most effective manner.

Limitorque has designed the QX actuator for long life even in the harshest environments. Flexible control and protec-

tion options are provided to ensure the actuator meets your requirements.

• All actuator enclosures are sealed by O-rings, and cable entries are supplied with threaded plugs to protect the

terminal compartment until the unit is wired. If the actuator cannot be installed immediately, it is recommended that

it be stored in a clean, dry place, preferably in an area that is not subject to large ﬂuctuations in temperature.

• Disconnect all incoming power before opening any cover on the actuator. The user/operator must ensure that safe

working practices are employed at all times and are in accordance with local or national standards that are enforced

at the particular site.

• To install and commission the actuator, only the terminal compartment cover needs to be removed. See Figure

1.1, Item 10. Settings for commissioning the actuator are done externally; therefore, no other covers need to be

removed. The actuator was assembled in ideal dry conditions and the total sealing of the enclosure protects all

electrical components against deterioration.

NOTE: Removal of any cover, other than the terminal compartment cover, will invalidate the unit warranty. Exposure

of actuator components to an environment that results in deterioration of internal components will also invalidate the

unit’s warranty.

• During ﬁnal ﬁeld installation, ensure that all cable entries are correctly sealed in accordance with National Standards

or Regulatory Authorities. All temporary transit plugs must be removed and any unused cable entries closed in an

approved manner. See Section 3.3.3, Sealing Cable/Conduit Entries.

2 Quick Start

Quick Start provides step-by-step instructions for commissioning each QX actuator. These instructions are for the

following:

• Position limits calibration – can be performed one of two ways:

1. Electrical operation: See Section 2.1.2, Electrical Operation Feature.

2. Handwheel operation: See Section 2.1.2, Handwheel Operation Feature.

• DDC operation: See Section 2.2, DDC Option.

When these Quick Start instructions are complete, the position limits will be set and the actuator will be ready for

normal operation.

NOTE: Units are shipped with default operating time values based on unit size:

QX-1: 5-20 sec, default 15 sec

QX-2: 8-30 sec, default 30 sec

QX-3: 15-60 sec, default 60 sec

QX-4: 30-120 sec, default 60 sec

QX-5: 60-120 sec, default 60 sec

These times are based on a 90° open to close span.

The operating time can be set as desired by following the instructions in document LMENIM3306, QX Actuator

Instruction, Operation and Maintenance Manual.

Limitorque QX Electronic Actuator FCD LMENIM3306-06 – 07/14

2.1Calibrate Position Limits

1. Conﬁrm that the QX actuator is correctly installed on the valve as described in Section 3 Installation and Operation.

2. Refer to the nameplate for the correct main power supply voltage. Switch on the main power to the unit.

3. Turn the red knob to the “STOP” position. The “SET UP ENGLISH?” message will be displayed, select “YES”. The

“SET CLOSE POSITION LIMIT?” message will then be displayed. Proceed with setting the open and close limits of

the valve.

4. Calibrate end position limits one of two ways:

• Electrically, using the control panel. See Section 2.1.1, Electrical Operation Feature.

• Manually, using the handwheel. See Section 2.1.2, Handwheel Operation Feature.

Once the position limits have been set, the LCD message will indicate the valve position as a percentage of the valve

opening.

While setting limit switches, place the red selector knob in the “LOCAL” position to permit the actuator to run open or

closed in push-to-run mode (inching) only.

a CAUTION: Extreme care must be taken as the valve approaches its end position.

The unit will not function with the red selector knob in the “REMOTE” position until both limit switches are set.

The existing conﬁguration of the actuator/valve parameters may be viewed by entering the “SETUP” mode.

2.1.1 Electrical Operation Feature

This feature allows for quick and simple calibration. From a virgin startup, the “SET CLOSE POSITION LIMIT?” message

will be displayed once the setup language has been selected.

NOTE: Refer to Figure 2.1 – Electrical operation as a guide during setup

a CAUTION: Do not adjust close stop while stop is loaded. It is highly recommended that the stops be turned until

they are almost removed from the housing before setting the limits. Once the limits have been set, then the

stops maybe tightened. Refer to Figure 2.3.

Closed Position Limit

1. “SET CLOSE POSITION LIMIT?” is displayed on the LCD.

2. Select “YES.” The “CLOSE VALVE - OK?” message is displayed.

3. Switch the actuator to “LOCAL” control and use the open/close switch to position the valve to the desired closed

position.

4. Back out the close stop if needed. First loosen the screw securing the stop then move stop.

NOTE: Do not adjust close stop while stop is loaded.

5. When the valve is in the desired position, switch the actuator back to “STOP” and select “YES” again. The LCD will

read “SAVE CLOSE LIMIT OK?”

6. Select “YES” if the valve’s close limit position is correct. The close position limit is set.

7. Turn the close stop against the drive sleeve, then back off the close stop from the drive sleeve approximately 0.5 to

1.5 turns, ensuring the stop does not contact the drive sleeve.
