! WARNING Read this manual carefully before installation and operation. Follow the instructions and integrate this unit into your system with care. This unit should be installed, operated and maintained by qualified personnel only. Improper installation can damage your system. Comply with all applicable codes.
INSTALLATION FMBES-CC NOTE The following sections are arranged by model. Verify that you are in the correct section for your model. 1. Remove the six Socket Head Cap Screws (Item 11) and separate the two halves of the FMBES-CC. 2. Using four Socket Head Cap Screws (Item 34) and Lock Washers (Item 35), secure the Female Pilot (Item 6) to the motor. Tighten the Socket Head Cap Screws to the recommended torque (See Figure 1 and Table 1). 29 Customer supplied key 30 3. Install the customer supplied key into the motor shaft (See Figure 1). 4. Reassemble the two halves of the FMBES-CC (See Figure 1). 5. Apply a drop of Loctite 242 to the threads of the six Socket Head Cap Screws (Item 11) (See Figure 1). 6. Reinstall the six Socket Head Cap Screws (Item 11); then, alternately and evenly tighten them to 65 In. Lbs. [7.3 N m] torque (See Figure 1). 7. Remove Pipe Plug (Item 30) (See Figure 1). 8. Tighten the Set Screw (Item 29) to lock the customer supplied key. Reinstall the Pipe Plug (Item 30) (See Figure 1). 11 FIGURE 1 TABLE 1 6 34/35 Motor RECOMMENDED TORQUE MODEL ITEM 34 625 48.3 Ft.

[161.0 N m] AIR CONNECTIONS NOTE For quick response, install a quick exhaust valve and short air lines between the Control Valves and the FMBES. Align the air inlet port to a down position to allow condensation to drain out of the Air Chamber of the FMBES. In high-cyclic applications, Nexen recommends a 50 ms delay between the solenoid valve and the motor starter. 1 FORM NO. L-20323-D-0300
LUBRICATION NOTE Pneumatically actuated devices require clean, pressure regulated, and lubricated air for maximum performance and long life. The most effective and economical way to lubricate the FMBES is with an Air Line Lubricator, which injects oil into the pressurized air, forcing an oil mist into the air chamber. Locate the lubricator above and within ten feet of the FMBES, and use a low viscosity oil such as SAE-10. Synthetic lubricants are not recommended. LUBRICATOR DRIP RATE SETTINGS NOTE These settings are for Nexen supplied lubricators. If you are not using a Nexen lubricator, calibration must replicate the following procedure. 1. Close and disconnect the air line from the unit. 2. Turn the Lubricator Adjustment Knob clockwise three complete turns. 3. Open the air line. 4. Close the air line to the unit when a drop of oil forms in the Lubricator Sight Gage. 5. Connect the air line to the unit. 6. Turn the Lubricator Adjustment Knob counterclockwise until closed. 7. Turn the Lubricator Adjustment Knob clockwise onethird turn. 8. Open the air line to the unit. MANUAL RELEASE OPERATION NOTE The Manual Release Set Screws (Item 26) must be alternately and evenly tightened to insure proper operation of the Manual Release feature. 1. Loosen the Jam Nuts (Item 27) until they are flush with the tops of the two Set Screws (Item 26) (See Figure 2). NOTE Count and record the number of turns required for the Set Screws (Item 26) to disengage the FMBES. 2. Alternately and evenly turn the Set Screws (Item 26) clockwise 1/2 turn at a time until the FMBES is released; then, secure the two Set Screws (Item 26) by turning the Jam Nuts (Item 27) until they are flush with the Housing of the FMBES (See Figure 2). 3. To engage the FMBES alternately and evenly turn the Set Screws (Item 26) counterclockwise the same number of turns required to release the FMBES; then, secure the Set Screws with the Jam Nuts (Item 27) (See Figure 2).

ACCESSORIES SHUTTLE VALVES a range of Shuttle Valves in different sizes, made from Brass or 316 Stainless Steel General Description VERSA Shuttle Valves are constructed of solid Brass or 316 Stainless Steel, with resilient seals providing tight shut off. Shuttle valves are 3/2 valves, primarily used to charge and discharge a pressure line or chamber from two - or more - sources. A typical schematic is shown below: Materials 1 2 3 Type: Brass Stainless Steel Body: Brass 316 Stainless Steel Shuttle: Nylon(Zytel) 316 Stainless Steel Seals: NBR (Nitrile) FKM (Fluorocarbon) Screws: Plated Steel 316 Stainless Steel Functional Description Shuttle Valves have a free moving shuttle that blocks one of two inlet ports while the other inlet port is connected to the (common) outlet port. When a pressure signal enters the port blocked by the shuttle, it will cause the shuttle to shift over to close the opposite inlet port. The shuttle will stay there while the line or chamber connected to the outlet port is charged and/or discharged and will only shift when pressure is applied to the inlet port it is blocking at that time. In logic terms a shuttle valve is an 'OR' - function. Pressures Pressure range Pneumatic: 5 to 200 psi (0.35 to 14 bar) Hydraulic: 5 to 500 psi (0.35 to 35 bar) Symbol Mounting IN OUT IN Preferably with the centerline of the two inlet ports horizontal.
