Switching action is obtained through the use of a magnetic sleeve and a float , displacer or flow sensing element and a switching mechanism . These two basic component assemblies are separated by a non-magnetic, pressure retaining enclosing tube . The switch and magnet are assembled to a mechanism with a swinging arm which operates on precision stainless steel pivots. 1.2 As level of a liquid in a vessel rises (Figure 1), the float rides on the liquid surface moving the magnetic sleeve upward in the enclosing tube and into the field of the switch mechanism magnet. As a result, the magnet is drawn in tightly to the enclosing tube causing the set screw on the swinging arm to move the actuating lever of a snap action switch, making or breaking the electrical circuit. As the liquid level recedes (Figure 2), the float and magnetic sleeve move downward until the switch magnet releases and is drawn outward, away from the enclosing tube by a tension spring. This, in turn, moves the actuating arm of the switch in the opposite direction, reversing switch action. 4 3 Pivot 5 1 2 Figure 1 Figure 2 Rising Level Falling Level Operating Cycle Switch mechanisms may include a single switch or multiple switches, depending on operational requirements and switching action desired. 1.3 Description The Series F, R, 8 & 9 dry contact switches are specifically designed for use in applications with extremely high process temperatures. These switches are available on most of Magnetrol’s buoyancy products and can also be retrofitted onto many existing controls. Designed to Magnetrol’s usual high standards, these high temperature switches will provide reliable, repeatable service in the toughest of applications. These switches are available with SPDT or DPDT contacts. Some models can be configured with multiple switch mechanisms for several actuation levels. FM, CSA and ATEX approval for hazardous and non-hazardous locations on approved models. 1.3.1 +750° F (+399° C) Dry Contact Switches • Series 8 & F switches are designed for high temperature applications and are hermetically sealed. 4 42-799 Series ‘F, R, 8 & 9’ Electric Switch Mechanisms 1.3.2 +1000° F (+538° C) Dry Contact Switches • Series R switches are designed for the highest temperature installations and have a 1.0 amp contact rating at 8 and 30 VDC. • Series 9 switches are hermetically sealed and designed for the highest temperature installations, and have a 1.0 amp contact rating at 120 and 240 VAC. 1.3.3 Basic Switch Ratings Rating (amps) Switch Series 8 9 F R Switch Type Hermetically Sealed Snap Hermetically Sealed Snap Hermetically Sealed Snap Snap Process Temp Range F (C) Volts AC Load Volts DC 120 240 480 24 48 120 240 -50 to +750 (-46 to +398) Non-Inductive 1.00 — — 3.00 — — — Inductive 1.00 — — 1.00 — — — -50 to +1000 (-46 to +538) Non-Inductive — — — 0.50 — — — Inductive — — — 0.50 — — — -50 to +750 (-46 to +398) Non-Inductive 2.50 — — 0.30 — Inductive 2.50 — — 2.00 — — 0.10 — -40 to +1000 (-46 to +538) Non-Inductive 1.00 1.00 — 1.00 — 0.40 — Inductive 1.00 1.00 — 1.00 — 0.40 — 4.00 Process temperature based on +100° F (+38° C) ambient temperature 28 VDC 2.0 Installation 2.1 Replacing Switch Mechanism Caution: Before attempting to remove a switch mechanism, be certain to pull disconnect switch or otherwise assure that electrical circuit through control is de-energized. 1. Disconnect wiring from supply side of terminal block on switch mechanism. Note and record lead wire terminal locations. Figure 3 Mounting Screw 42-799 Series ‘F, R, 8 & 9’ Electric Switch Mechanisms 2. Loosen mounting screw in split mounting clamp until mechanism slides freely on enclosing tube, refer to Figure 3. 3. Remove small round head screw securing lower switch mechanism to baffle plate, refer to Figure 4. 4. Slide switch mechanism off of enclosing tube. If mechanism is to be reused, ensure that it is placed on a clean surface, free of metallic particles that may be attracted to the switch magnet. 5. Loosen mounting screw so that switch frame will fit over e-tube. Install switch mechanism by sliding it over the enclosing tube. Slide mechanism down until the bottom of the frame and terminal block are resting on the baffle plate. The baffle plate should be resting on the hub of the housing base. 5 2.1 Replacing Switch Mechanism (cont.) 6. Install and tighten baffle plate screw so that the switch mechanism may not be separated from the baffle plate. Tighten the mechanism mounting screw so that the mechanism is firmly clamped to the enclosing tube. 7. Swing magnet assembly in and out by hand, checking carefully for any signs of binding. 8. Reattached supply-side wiring to the terminal block and check switch function by varying liquid level in the vessel. Baffle Plate Screw 2.2 Figure 4 Replacing Dry Contact Switches Baffle Plate Screw 1. Disconnect control from power supply. 2. Disconnect switch leads from terminal block. Note and record terminal connections of switch to be replaced. 3. Remove two mounting screws holding existing switch, refer to Figure 5. 4. Remove existing switch and install replacement switch in the same position, tightening mounting screws securely. NOTE: For proper operation of the replacement switch, it must actuate in the middle portion of the pivoted magnet’s swing. Adjusting Screw Mounting Screws 5. Check switch action and adjust as follows: a. Slowly rotate the pivoted magnet by hand, back and forth through its angle of swing, listening closely for the actuating click of the switch in each direction. b. Check to see if there is equal overtravel of magnet in its swing after the switch click in either direction. c. If switch actuation is not correct, change adjustment of actuating screw using a 1⁄16" hexagon key wrench, refer to Figure 5. 6. Reconnect power supply and test switch action by varying liquid level in the vessel.

In such cases, credit for the materials returned will be determined on the basis of the applicability of our warranty. 1. 2. 3. 4. 5.
