fisher 3660 manualRefer to separate instruction manuals for information on the actuator and control valve. Do not install, operate, or maintain a 3660 or 3661 positioner without being fully trained and qualified in valve, actuator and accessory installation, operation and maintenance. To avoid personal injury or property damage it is important to carefully read, understand, and follow all of the contents of this manual, including all safety cautions and warnings. If so, the factory mounts and calibrates the positioner and connects the positioner to actuator tubing. If the positioner is ordered separately from the actuator, perform the appropriate mounting procedure. Other key numbers are shown in either figure 24 for the 3660 positioner or figure 25 for the 3661 positioner.Figure 7 shows keys 69 and 70, 73 through 78, and 82 through 93. Other key numbers are shown in either figure 24 for the 3660 positioner or figure 25 for the 3661 positioner. Feedback Lever Assembly and Range Spring Installation Key numbers are shown in either figure 24 for the 3660 positioner or figure 25 for the 3661 positioner.

To avoid personal injury and property damage caused by the release of pressure or process fluid, provide some temporary means of control for the process. Refer to figure 24 (3660) or figure 25 (3661) for key number locations unless otherwise indicated. Adjustment locations are shown in figure 19. Tables 7 and 8 show some typical split ranges for the positioners. In these cases, bypassing the positioner sends the input signal directly to the actuator. Such a change will affect the desired operation and possibly. Use bypass operation only when the instrument signal range is the same as the positioner output range required for normal actuator operation. Labels on the bypass body assembly (key 41, figure 23), and a pointer on the bypass lever (key 42 in figure 23) indicate if the input signal from the instrument goes to the positioner or directly to the control valve actuator. Changing the Input Signal Range on 3660 Positioners To change the input signal range from 0.2 to 1.0 bar (3 to 15 psig) to 0.4 to 2.0 bar (6 to 30 psig) or vice versa, change the input diaphragm assembly (key 28, figure 24) by performing the Changing the Input Module Diaphragm Assembly procedure in this Maintenance section. Disconnect the supply, instrument, and output tubing. For 3661 positioners, disconnect the input wires and conduit. 2. Unscrew the two captive cover screws and remove the cover (keys 24 and 21). Loosen the retaining screw (key 19P). Disconnect the supply, instrument and output tubing. Keys 43, 44, 45 and 49 are used for the 3660 with bypass only. Note Contact your.

Description3660 pneumatic and 3661 electropneumatic, singleacting positioners are used with Fisher 657, 667, 1250, 1250R,3024S, and GX actuators. These positioners can also be mounted on Baumann actuators. Figure 1 shows a 3660positioner mounted on a Baumann actuator. The positioner mounts on the actuator and provides the desired plug position for a specific input signal. The 3660positioner accepts a pneumatic signal and the 3661 accepts a 4 to 20 milliampere DC input signal.See figure 2 for mounting. Bending Documents Positioners. Easily adjustable gain and damping adjustments fine tune the positioner stability to specific application requirements. Positioner accepts a standard pneumatic input signal from a control device. This positioner provides split range capabilities and adjustable zero and spans. Most of the parts for the 3660 positioner are interchangeable, requiring fewer spare parts to support these positioners. The case and cover are designed to withstand mechanical vibration and rough handling. Zero and span adjustments can be made with the cover in place. These rugged positioners provide a valve position proportional to a pneumatic input signal received from a control device. Tideflex Viking Johnson.

Install feedback lever arm assembly so pilot shaft is on top of the feedback plate. 2 When mounting on Baumann actuators, install feedback plate so lip is down. The instrument pressure acts on the input module, which controls the flapper nozzle system of the relay. Supply pressure is applied to the relay, and the output pressure of the relay is supplied to the control valve actuator. For a direct acting positioner, increases in instrument pressure causes the input module to pivot the beam. The beam pivots the flapper and restricts the nozzle. The nozzle pressure increases and causes the relay assembly to increase output pressure to the actuator. With a direct acting actuator, this increased pressure moves the actuator stem downward. Stem movement is fed back to the beam by means of a feedback lever and range spring, which cause the flapper to pivot slightly away from the nozzle to prevent any further increases in relay output pressure. The positioner is Figure 2. Operational Schematic Product Bulletin once again in equilibrium but at a higher instrument pressure, a slightly different flapper position, and a new actuator stem position. A decrease in instrument pressure decreases nozzle pressure, which allows the relay to bleed off actuator loading pressure. Operation of a reverse acting positioner is similar except that the flapper position is reversed from that shown in figure 2. The reversed position uses the alternate flapper pivot point so that increases in instrument pressure rotate the flapper away from the nozzle to reduce nozzle pressure. With a 3661 electro pneumatic positioner, the electro pneumatic converter provides a 0.2 to 1.0 bar (3 to 15 psig) output pressure proportional to the 4 20 ma input signal. The 0.2 to 1.0 bar (3 to 15 psig) output pressure becomes the input signal pressure to the input module. If the supply source is capable of exceeding the maximum actuator operating pressure or positioner supply pressure, appropriate steps must be taken during installation to protect the positioner and all connected equipment against overpressure.

If you let your ears be the judge, you will find it unusually simple to choose the Fisher Receiver and pair of Fisher Speaker Systems that best perform to your personal listening taste. Fisher receivers are available in moderately priced, deluxe and luxury class models. Each model, regardless of cost, will not sound strikingly different, for each is designed to the same high standard of performance. They differ greatly in all other aspects, such as flexibility of control, power output rating, conveniences, number of input and output connections, physical size, engineering circuitry, and general appearance. The Fisher 160-T 40-Watt FM-Stereo Receiver HERE IS the world's first high quality pushbutton FM-Stereo Receiver. You can push-tune any of your five favorite FM stations at the press of a button. You can tune the same five vertical FM dials separately, by hand. You can connect tape recorder and phonograph and be assured of a breadth of flexibility generally associated with professional equipment. You can channel the musical program into any room of the home, or listen through stereo headphones in absolute privacy. Whatever station you have manually tuned in, Automatic Frequency Control (AFC) locks it within a diode memory bank. Thereafter, whenever you press the button, even after you have tuned in other stations on the dial, the set tunes instantly to the perfect center-of-channel for reception of that originally desired station. No 'off-center' drift. WEIGHT: 15 pounds. The Fisher 175-T 65-Watt AM-FM Stereo Receiver THE FISHER 175-T is a landmark in high fidelity engineering. It is the first high-powered receiver with professional AM and FM-Stereo facilities to be offered at half the cost one would expect to pay. In terms of total performance, the Fisher 175-T is unquestionably the finest value in the AM-FM Receiver category. It has 65 watts of music power at 8 ohms — a measurement that conforms to the impedance of virtually every speaker system of good quality.
