APPLICATION

The V4062 Gas Valve Actuator in combination with a V5055 or V5097 Gas Valve provides three-position control of the gas supply to commercial and industrial burners.

FEATURES

• When energized, the V4062 Actuator opens the V5055/

V5097 Gas Valve to the low-fire position. The actuator opens the valve to the fully open position when the line voltage contacts are made.

• When used with the V5055, V5097 or VE5000 Gas

Valve, the combination is rated for final safety shutoff service.

• Although the V4062 can be used with all V5055 or

V5097 Valve models, the V5055/V5097B with characterized guide is recommended for optimum control and low-fire repeatability

4. After installation is complete, check out product operation as prided in these instructions.

WARNING

Electrical Shock Hazard.

Can cause serious injury or death.

Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.

IMPORTANT

1. All wiring must comply with all applicable electrical codes, ordinances, and regulations. All wiring must be NEC Class 1.

2. Voltage and frequency of the power supply connected to this control must agree with those marked on the device.

3. Loads connected to the auxiliary switch and/or proof-of-closure switch, if used, must not exceed the ratings given in the Specifications section.

4. When replacing a V6034 Actuator with a V4062, the

V5034 Valve body must be changed to a V5055

Valve.

5. Do not attempt to use the V4062 Actuator with the

V4055/V5034 Adapter. Differences in stem travel can prevent correct low fire adjustment.

Install Valve

The actuator is installed directly on the V5055/V5097 body after the valve is installed in the gas supply line. Refer to the instructions packed with the V5055/V5097 Gas Valve for installation details. When installing the valve, assure that:

1. Sufficient clearance is allowed for actuator installation and service.

2. Ambient temperatures at the valve location do not exceed actuator ratings.

3. Position of the valve permits damper hookup if one is controlled.

Install Accessory Switches (If Needed)

An spdt switch can be installed to operate an auxiliary load up to 1/2 hp (0.37 kW). The switch can be adjusted to operate at any point in the valve stroke.

A proof-of-closure switch can also be installed with a V5055/

V5097C or E Valve (with double seal) on any V4062 Actuator to provide a valve seal overtravel interlock. The spdt proof-ofclosure switch is installed to make or break a circuit when the valve is in the closed position. The switch is not adjustable.

Mount Actuator On Valve

Check the final position of the V5055/V5097 Valve body to be sure that the actuator will be in the proper position when mounted on the valve. This is especially important when the actuator is used to drive a damper.

If two smaller size valves are mounted very close together, as in an Industrial Risk Insurers type valve train, it may be necessary to mount the actuators off center to provide adequate clearance.

Slip the bottom collar of the actuator over the valve bonnet assembly. Rotate the actuator to the desired position and use a 5/32-inch Allen wrench to securely tighten the two setscrews (50 to 60 lb-in. [5.7 to 6.8 N•m]). Connect the damper linkage, if used. Refer to the instructions packed with the damper crank arm.

Mount and Adjust 7616BR Damper Crank

Arm (If Used)

The damper crank arm provides a maximum travel of

2-5/16 in. (58.7 mm) through a stroke of 52 degrees. See

Fig. 3. If the V4062 has a damper shaft return spring, dampers go to the closed position when power is interrupted by the programmer. Refer to the instructions packed with the

7616BR Damper Crank Arm for complete installation information.

WIRING

Wiring must comply with all applicable electrical codes, ordinances, and regulations. Wiring to the actuator and to the controller must be NEC Class 1.

Connect the power from the flame safeguard control to terminals 1 and 2 on the V4062 terminal strip, and connect the firing rate controller to terminals 3 and 4. Refer to Fig. 4 for typical connection. Fig. 5 shows the wiring for connecting the Max Flow Limit Switch to the actuator. For other typical system hookups, refer to the instructions packed with the device used to control the valve.

When all wiring connections are complete, replace the actuator faceplate.

ADJUSTMENTS

Low-Fire Adjustment

The low-fire position is adjustable from 0.16 in. to 0.64 in.

(with respect to V5055/V5097B Valve) valve stem travel. A dial on the low-fire cam (Fig. 6) indicates the low-fire setting.

Because the cam rotates as the valve opens, scales are marked on the dial so the low-fire setting can be observed with the valve in any position. One scale is visible when the actuator is closed, and the other is visible when it is open.

These scales are not independent; the same setting applies to both. The low-fire setting is adjusted either before the actuator is installed or after the entire system is operational.

Refer to form 70-8311 for valve flow (capacity) curves.

IMPORTANT:

When using the V4062 with a V5055/V5097C or E

Valve (with double seal), match low-fire minimum position to burner and application. Too low a position could result in loss of burner flame. This low-fire position should also be checked at periodic maintenance intervals.

For most effective use of the V4062/V5055 or V4062/V5097, be sure to select a valve body size closely corresponding to burner capacity. An oversized valve might not allow the lowfire rate to be adjusted to the desired minimum setting.

The V4062 Actuator is shipped from the factory with the lowfire setting at MAX to provide a valve gas flow of approximately 50 to 60 percent, which is adequate for safe lightoff until the final setting can be determined.

V4062A,B,D HI-LO-OFF FLUID POWER GAS VALVE ACTUATOR

Recommended Procedure

To adjust the low-fire setting without energizing the actuator, proceed as follows:

1. Remove the wiring compartment cover.

2. Manually rotate the cam and dial assembly downward so that the setscrew is accessible from the front of the actuator.

3. Loosen the setscrew on the low-fire cam using the special wrench (supplied taped to the inside of the actuator cover).

4. Set the cam to the predetermined low-fire setting for the burner being used.

5. Tighten the setscrew in the cam.

6. Replace the wiring compartment cover.

Alternate Procedure

To adjust the low-fire setting after the burner is in operation, use the following instructions:

1. Remove the wiring compartment cover.

2. Check to be sure the low-fire adjustment is set at MAX to assure a safe lightoff. (Low-fire adjustment is preset at the factory in the MAX position.)

3. Disconnect the firing rate controller leadwire from terminal 4 on the actuator to keep the valve in the lowfire position (Fig. 4).

4. Start the system and establish the main burner flame.

5. Loosen the setscrew in the cam (Fig. 5) with the special wrench. Keep the wrench seated in the setscrew. Rotate the cam slightly downward (by moving the wrench toward the actuator base) to open the bleed valve. The actuator will start to close.

6. When the valve reaches the desired low-fire position, quickly tighten the setscrew and remove the wrench. If the desired low-fire setting is missed, loosen the setscrew and rotate the cam in the opposite direction to the desired setpoint.

7. Shut down the burner, and then restart. Repeat several times to be sure the low-fire setting is suitable for correct burner lightoff. Readjust, if necessary.

8. Disconnect power and reconnect the controller leadwire removed in step 3.

9. Replace the wiring compartment cover.

Adjust Auxiliary Switch (If Used)

The auxiliary switch can be adjusted to operate at any point in the actuator stroke. After installing the switch in the actuator, turn the adjustment screw (Fig. 2) clockwise to cause the switch to operate earlier in the stroke or turn counterclockwise to cause the switch to operate later in the stroke.

NOTE: The proof-of-closure switch is not adjustable.

Adjust Max Flow Limit Switch (Fig. 2)

The Max Flow Limit Switch is adjustable throughout the actuator stroke. With the switch installed in the actuator, turn the adjusting screw clockwise to cause the switch to operate earlier in the stroke (less flow) or counterclockwise to cause the switch to operate later in the stroke (more flow).

OPERATION

To function as intended, the V4062 must be connected to a properly sized valve. Too large a valve will not properly control the gas flow.

When the actuator is energized, it drives to the adjustable low-fire position. Depending on the demand of the controller, the valve remains at low-fire or moves to the high-fire position. When the firing rate controller calls for no heat, the actuator returns the valve to the low-fire position. When power to the actuator is interrupted, the valve completely closes.

Fig. 4 shows the V4062 in a typical flame safeguard control system.
