4.

CAUTION

Electrical Shock and Equipment Damage Hazard. Can cause serious injury or death.

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

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

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

4.Maximum total connected load to both switches (if used) must not exceed 1800 VA.

WARNING

Explosion Hazard.

Can cause explosion, serious injury or death.

1.Turn off gas supply before starting installation.

2.Disconnect power supply for valve actuator before beginning installation.

3.Install the valve so the arrow on the valve body points in the gas flow direction.

Install Valve

The actuator is mounted directly on the valve bonnet after the valve is installed in the gas supply line. Refer to the instruction sheet packed with the gas valve for details of installation. When installing the valve, ensure that:

1.Sufficient clearance.is left for installation and service of the actuator.

2.Ambient temperatures at the valve location will remain within -40??F to +150??F (-40??C to +66??C).

Install Accessory Switches (If Needed)

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

A valve-closed indication switch may also be installed on any V4055 actuator to provide a valve seal overtravel interlock (valve-closed indication) when used with a V5055C or E valve (with double seal).

Fig. 2. V4055 actuator with cover removed.

NOTE: A V5055A, B or D valve can also be fitted with a bon- net assembly with 2 seals to provide a valve seal overtravel interlock.

The SPDT valve-closed indication switch is installed to make or break a circuit when the valve is in the closed position. The switch is not adjustable.

NOTE: Mark the actuator or valve to indicate any changes made.

To install the switches, proceed as follows:

1.Remove the actuator faceplate (2 screws).

2.Remove the silver-colored barrier to expose the actuator stem.

3.Insert the auxiliary switch in the position indicated in Fig. 2. Fasten with 2 screws through the actuator base.

4.Insert the valve-closed indication switch in the position shown in Fig. 2. The valve-closed indication switch mounts against the side of the actuator housing. The mounting holes are spaced to mount the switch only in the correct position. Fasten with 2 screws through the actuator base.

5.If only 1 switch is used, install the narrow barrier included with the switch in the unused space.

6.Mount the actuator before making wiring connections and adjustments to the switch.

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 tighten the two setscrews securely (50 to 60 Ib.-in. [5.7 to 6.8 N.m]).

WIRING

Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage. Wiring must comply with all applicable electrical codes, ordinances, and regulations. Wiring to the actuator must be NEC Class 1.

Connect the power supply to terminals 1 and 2 on the V4055 terminal strip. Refer to Fig. 3 for auxiliary switch connections. For typical system hookups, refer to instructions packed with device used to control valve.

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

NOTICE: Per Industry Standards, the actuator is required a conduit seal or a cable type that is sealed be installed in a device that can result in a flammable liquid flow through a conduit or cable to an electrical ignition source in the event of a seal leakage or diaphragm failure.

Adjust The Auxiliary Switch (If Used)

The auxiliary switch is adjustable throughout the stroke of the actuator. With the switch installed in the actuator, turn the adjusting screw (Fig. 2) clockwise to cause the switch to operate earlier in the stroke or counterclockwise to cause the switch to operate later in the stroke.

NOTE: The valve-closed indication switch is not adjustable.

CHECKOUT AND SERVICE

CAUTION

Only a trained, experienced, flame safeguard control service technician should check out and service this control.

Checkout

After the installation is complete, cycle the valve several times with the manual fuel shutoff cock closed before testing the system in actual operation.

Service

The actuator is not field repairable, except for replacing the auxiliary switch, valve-closed indication switch, and READY TO OPEN light. See INSTALLATION section for procedure. Do not disassemble the valve actuator.

If the actuator should fail to operate properly, replace it.

1.Turn off the gas supply at the manual shutoff valve located upstream from the valve(s) being serviced.

2.Shut off all electrical power to the valve actuator(s).

3.Mark and disconnect the wires from the actuator termi- nals. Remove conduit and disengage the damper linkage assembly (if applicable.

4.Loosen the two set screws from the valve to lift off the actuator.

5.If the actuator is to be replaced and it did not leak hydraulic fluid, skip to Step 11.

NOTE: It is good practice to inspect the inside of the valve whenever the actuator is replaced. To do so, remove the bonnet assembly, inspect the valve and bonnet. If all is well, proceed to Step 7.

6.If the actuator leaked hydraulic fluid onto the valve (the fluid is red), it must be cleaned off from the valve and bonnet assembly.

a.Wipe off the outer valve body.

b.Remove the valve bonnet bolts and lift off the bonnet.

NOTE: V5055/V5097C and E Valves have additional internal springs that will push the bonnet up as the bolts are loosened.

the bonnet assembly is seated. Tighten the remaining bolts. Torque the bolts as follows:

11.Remount the actuator on the bonnet assembly. Tighten the two set screws (50-60 inch pounds.

12.Replace the damper crank arm assembly.

13.Re-attach the wires removed from the actuator terminals and turn on the electrical power.

14.With the gas still off, cycle the actuator to check for proper mechanical operation.

CAUTION

Be sure to perform a bonnet seal and seat leak check after installation.

Be sure to read and follow all instructions that come with the actuators, valves, seal and bonnet kits.

Table 3. Replacement Bonnets for

V5055/V5097 Gas Valves.

c. Inspect the inside of the valve.

IMPORTANT

If fluid is present on the inside surfaces of the valve body or bonnet surfaces, the bonnet assembly or entire valve must be replaced. See Table 3 below for the bonnet assembly part number.

d.If the inside surfaces are clear of hydraulic fluid, clean the bonnet assembly and be sure to remove all hydraulic fluid from the inside and outside of the actuator mounting curb. This is the ???cup-like??? area around the valve stem. Avoid using a cleaning solu- tion as it may damage the rubber seals used in the valve.

7.If the valve bonnet assembly is in good condition and is not replaced, replace the bonnet seal. Do not reuse the old bonnet seal. See Table 4 below for the seal number.

8.Coat seals with grease provided and position in valve body/bonnet assembly.

9.Carefully seat the bonnet assembly on the valve body. Be sure the seals are in their proper position. On those valves with a spring below the disc, be sure the spring is centered in the indentation on the inside of the valve body.

10.After positioning the bonnet assembly, replace the screws removed earlier.

NOTE: When replacing the bonnet assembly on the 4- inch valve, draw it evenly into the valve body. Finger-tighten the eight bolts. Draw the bonnet assembly into the valve by tightening, in order, bolts 1, 5, 7 and 3 (two turns each). Repeat until

**Each replacement assembly contains the bonnet assembly, two rubber seals, and a tube of grease. It must be used only on the type of valve indicated above.
