G Lubrication Requirements NOTE: Lubricants other than those listed in steps 1.6.1 should not be used without prior written approval of Bettis Product Engineering. 1.6.1 1.7 General Tool Information 1.7.1 1.8 All temperature services (-50°F to +350°F)/(-45.5°C to 176.6°C) use Bettis ESL-5 lubricant. ESL-5 lubricant is contained in the Bettis module service kit in tubes and the tubes are marked ESL-4, 5 and 10 lubricant. Tools: All tools/Hexagons are American Standard inch (Imperial). Large adjustable wrench, two (2) large screwdrivers, Allen wrench set, set of open/box-end wrenches, rubber or leather mallet, torque wrench (up to 1600 foot pounds / 2169 N-m), breaker bar, and a drive socket set. For recommended tool and wrench sizes refer to Section 6, Tables 6.2 through 6.10. Actuator Storage For applications where the actuator is not placed into immediate service, it is recommended that the actuator be cycled with regulated clean/dry pneumatic pressure at least once per month. Indoor storage, if available, is recommended for all actuators. Care should be taken to plug all open ports on actuator and controls to keep out foreign particles and moisture. Actuators should not be stored in an atmosphere that is harmful to resilient seals. Contact factory for extended storage period. 1.9 Actuator Installation 1.9.1 1.9.2 Since there are many valve and actuator combinations, it is not practical to include detailed instructions for each type. Mountings are designed to be as simple as possible to keep the guess work out of the installation. Actuators that are shipped from the factory with the travel stops adjusted for approximately ninety degree rotation. Generally, it is necessary to make slight travel stop adjustments once the actuator is installed onto the valve. Refer to the valve manufacturer's recommendations for specific requirements. When the valve has internal stops, the actuator should be adjusted at the same points. NOTE: The actual "stopping" should be done by the actuator. If the valve does not have internal stops, adjust the actuator to the full open position. Using this as a reference point, rotate the valve closed and adjust to the valve manufacturer's specifications for total rotation. 4 Introduction Section 1: Introduction Service Instructions 124840E Rev. G 1.9.3 March 2017 Good instrument practices are also recommended. Clean/dry regulated pneumatic pressure is essential for long service life and satisfactory operation. It should be noted that new pneumatic lines often have scale and other debris in them and these lines should be purged of all foreign material. NOTE: Scale and debris can damage control valves, solenoids, and seals. 1.10 Actuator Start-up 1.10.1 Prestart-up checks 1. Inspect to ensure the unit has been mounted onto valve properly. Gear flange mounting bolts, stem key, setscrew(s) are installed and secured. 2. No tubing damaged or accessories dislodged during the shipping or the installation. 3. Indicated position confirms valve position. 4. All switching valves in normal operating position as per SCHEMATIC / INSTRUCTIONS 1.10.2 Check Connections 1. Pneumatic / hydraulic components connected as per schematic enclosed or in service manual supplied. 2. Pneumatic supply connected to the identified ports. 3. Electrical connection terminals are secured. 4. Wiring as per enclosed diagram or service manual supplied. 1.10.3 When actuator is first placed into service, it should be cycled with regulated pneumatic pressure. This is necessary because the seals have been stationary, causing them to take a "set". Therefore, the actuator should be operated through several cycles to exercise the seals so as to achieve a service ready condition. 1.10.4 The actuator speed of operation is determined by a number of factors includes: 1. Power supply line length Introduction 2. Power supply line size 3. Power supply line pressure 4. Control valve and fitting orifice size 5. Torque requirements of the valve 6. Size of the actuator 7. Setting of speed controls 8. Hydraulic Manual Override (where available) 5 Section 1: Introduction Service Instructions March 2017 124840E Rev. G 1.10.5 Due to the interaction of these variables, it is difficult to specify a "normal" operating time. Faster operating time may be obtained by using one or more of the following: 1. Larger supply lines 2. Larger control valve 3. Higher supply pressure * 4. Quick exhaust valves — * Not to exceed maximum operating pressure of actuator or control components 1.10.6 Slower operating time may be obtained by using flow control valves to meter the exhaust. Excessive exhaust flow metering may cause erratic operation. 1.11 Actuator Operation 1.11.1 Controlled Operation: Controlled operation is accomplished by pressurizing and/or depressurizing the appropriate cylinder inlet(s) of a double-acting. Do not exceed pressures indicated on actuator nameplate. 1.11.2 Manual Operation: All pressure must be vented or equalized on both sides of the pneumatic piston prior to manual operation. 6 Introduction Section 2: Actuator Disassembly Service Instructions 124840E Rev. G March 2017 Section 2: Actuator Disassembly 2.1 General Disassembly WARNING: DANGEROUS GAS AND/OR LIQUIDS It is possible, that the actuator may contain a dangerous gas and/or liquids. Ensure that all proper measures have been taken to prevent exposure or release of these types of contaminants before commencing any work. 2.1.1 Section 2 - Actuator Disassembly is written to either completely disassemble the entire actuator or can be used to disassemble individual modules as needed (pneumatic power module or drive module, etc.). WARNING: BEWARE OF COMPRESSED SPRING Do not remove spring module while spring is compressed WARNING: READ WARNING TAGS Actuators equipped with a spring cartridge mounted M3 jackscrew or an extended stop (ES) read warning tag wired to the spring cartridge cover plate 2.1.2 2.1.3 2.1.4 2.1.5 Actuator Disassembly When the spring module is to be removed it should be removed from the drive module prior to the pneumatic power module removal or disassembly. The pneumatic power module can be disassembled while still attached to the drive module or the pneumatic power module can be removed from the drive module and disassembled separate to the actuator (refer to Section 5 - Module Removal And Installation). To ensure correct re-assembly; that is, with pneumatic power module or spring module on same end of drive module as was, mark or tag right (or left) and mark mating surfaces. For spring module removal refer to Section 5 step 5.1. 7 Section 2: Actuator Disassembly March 2017 2.2 Service Instructions 124840E Rev.

Actuator Testing 3.9.1 Leakage Test - All areas where leakage to atmosphere may occur are to be checked, using a commercial leak testing solution. CAUTION: DO NOT EXCEED OPERATING PRESSURE Pressure applied to the actuator is not to exceed the maximum operating pressure rating listed on the actuator name tag. Test the actuator using a properly adjusted self relieving regulator, with gauge. 3.9.2 3.9.3 3.9.4 Cycle the actuator five times at the nominal operating pressure (NOP) as listed on the actuator name tag or the customer's normal actuator supply pressure. If excessive leakage across the pistons is noted, generally a bubble which breaks three seconds or less after starting to form, cycle the actuator five times as this will allow the seals to seek their proper service condition. Apply NOP pressure to the pressure port in inner end cap (3-10) and allow the actuator to stabilize. Apply a commercial leak testing solution to the following areas: 3.9.4.1 Joint between inner end cap (3-10) and cylinder (3-70). This checks cylinder to inner end cap O-ring seal. 3.9.4.2 The port hole in the outer end cap (3-80). This checks the piston D-seal to cylinder (3-70), O-ring seal (4-70), and rod T seal (4-50). NOTE: If excessive leakage across the piston remains, the actuator must be disassembled and the cause of leakage must be determined and corrected. 3.9.4.3 The vent check port hole in housing. This checks Polypak seal (4-30) that seals piston rod (3-40) to inner end cap (3-10). 3.9.4.4 Remove pressure from the pressure inlet port. 32 Actuator Reassembly Service Instructions Section 3: Actuator Reassembly 124840E Rev. G 3.9.5 3.9.6 March 2017 If an actuator was disassembled and repaired, the above leakage test must be performed again. Shell Pressure Test – Optional pressure test could be performed on PED certified actuator by applying pressure to both sides of the piston simultaneously for a period of two (2) minutes. If any leakage occurs across a static seal, the unit must be disassembled and the cause of leakage determined and corrected. WARNING: PED PRESSURE TESTING The actuators main pressure bearing parts will be tested in controlled conditions in accordance with the requirement of PED by pressuring both sides of the piston to avoid damage and over torquing of the actuator components. If further future testing in the field is necessary, Emerson should be contacted for guidance. Actuator Reassembly 33 Section 4: Field Conversions March 2017 Service Instructions 124840E Rev.

G Section 7: Troubleshooting 7.1 Fault Insertion In the unlikely event of a fault developing, the following Fault Location Table is provided to assist the service engineer to perform troubleshooting. This table is designed to cover as wide a range of Emerson Bettis actuators as possible. Reference to equipment not supplied should be ignored. Table 23. Fault Location Table SYMPTOM POTENTIAL CAUSES REMEDY Irregular supply of operating medium Inadequate lubrication Check operating medium for consistent supply pressure and correct as necessary Dismantle, relubricate and reassemble Dismantle. Visually inspect for significant wear. Actuator replacement may be required Erratic movement Worn parts Defective valve Consult the valve OEM's documentation Incorrectly set stops (valve and /or actuator) Short stroke Apparent lack of torque 54 Check the position of the travel stops and readjust as necessary Dismantle, remove any hard grease, Hardened grease Relubricate and reassemble Disassemble cylinder assembly to remove Debris left in the cylinder or debris. Reassemble cylinder assemble as housing during maintenance necessary Consult the valve manufacturer's Defective valve documentation Ensure supply pressure is above the minimum operating pressure of the actuator and that Inadequate supply pressure output torque produced at supply pressure exceeds valve torque demand Incorrect speed control settings Adjust speed controls to increase flow Remove and clean the exhaust port silencers Exhaust port blocked and replace Examine the pipe work for blockages, Pipe work blocked, crushed crushed pipe or leakage. Clear or replace as or leaking necessary Examine the controls, refurbish or renew as Defective controls necessary. Refer to component manufacturer's documentation Dismantle the cylinder assembly, remove Defective piston seal the defective piston seal. Fit new seal and reassemble Dismantle the cylinder assembly, remove the Defective rod seal defective rod seal. Fit new seal and reassemble Dismantle the housing assembly, remove the Defective housing seal defective seal. Fit new seal and reassemble High valve torque or valve seized Consult the valve OEM documentation Troubleshooting Service Instructions Section 7: Troubleshooting 124840E Rev. G 7.2 March 2017 Operational Test 7.2.1 7.2.2 Full Stroke Test The “Full Stroke Test” (“On-line”) must be performed to satisfy the PFDAVG (average probability of failure on demand) value. The full stroke test frequencies will be defined by the final installer to achieve the defined SIL level. 7.2.1.1 Procedure 7.2.1.1.1 Stroke the actuator/valve assembly two complete open/close cycles with complete closing of the valve. 7.2.1.1.2 Verify the open/close cycles functioned correctly (e.g. check locally, or automatically via Logic solver, the correct movement of the actuator/valve). Upon successful completion of the above described Full Stroke Test procedure, the “Test Coverage” can be considered 99%. Partial Stroke Test (when requested) The “Partial Stroke Test” (“On-line”) can be performed to improve the PFDAVG value and to satisfy PFDAVG (average probability of failure on demand) value. A typical partial stroke value is 15% of the stroke and the recommended test interval is about every one to three months. 7.2.2.1 Procedure 7.2.2.1.1 Operate the actuator/valve assembly for No° 1 open/close cycles 15% of the stroke. 7.2.2.1.2 Verify the partial stroke test functioned correctly (e.g. check locally, or automatically via logic solver, or via the PST system the correct movement of the actuator/valve was 15% of the stroke). NOTE: The above test is only applicable on systems equipped with a partial stroke feature. Troubleshooting 55 Section 8: Removal and Decommissioning March 2017 Service Instructions 124840E Rev. G Section 8: Removal and Decommissioning 8.1 Removal and Decommissioning WARNING: FOLLOW PROPER PROCEDURE Always follow safe work practices remove and disassemble G-Series actuator. The below basic procedure should not supersede or replace any customer’s plant safety or work procedures. If a conflict arises between this procedure and the customer's procedures, the differences should be resolved in writing between an authorized customer’s representative and an authorized Emerson/Bettis representative. CAUTION: ISOLATE AND POWER OFF ACTUATOR Make sure actuator is isolated before removing from valve. Turn OFF the power medium and bleed off all pressure first, including storage tank (if present). Next, bleed off pilot pressure, disconnect: pneumatic pressure supply, pilot tubing and electrical wiring (if equipped). Before starting the disassembly, a large area should be created around the actuator so to allow any kind of movement. Separate the parts composing the actuator according to their nature (ex. metallic, and plastic materials, fluids etc.) and send them to differentiated waste collection sites, as provided for by the laws and provisions in force. 8.1.1 8.1.2 8.1.3 56 Drain tanks and remove tubing from actuator. Remove accessories (if equipped) and controls from actuator. Remove all equipment mounted on top of actuator (limit switches, end of stroke valve, and relevant pneumatic/electric connection, etc.) Remove mounting bolts and actuator is ready to be removed from valve. For complete actuator tear down refer to Section 2 of the manual. Removal and Decommissioning Service Instructions Section 9: Document Revision 124840E Rev.
