We appreciate your business! Please take a few minutes to familiarize yourself with your FLX and this manual. The FLX contains up to seven reed switches in a 1/2" Ø stainless steel stem and permanent magnets in the floats. As each float rises or falls with the level of the liquid, the magnet inside the float acts on the corresponding reed switch inside the stem to provide SPST switching action. The FLX carries explosion proof and non-incendive hazardous location approvals. Reading your label Every APG instrument comes with a label that includes the instrument's model number, part number, serial number, and a wiring pinout table. Please ensure that the part number and pinout table on your label match your order. Class I Division 1, Groups C, and D T3 Ta 40°C C US 237484 Rated: 220 Volts, 0.5 A max, or 24 VDC, 0.5 A max.

Grey Grey Grey 4 CHAPTER 2: INSTALLATION AND REMOVAL PROCEDURES AND NOTES Tools Needed · Wrench sized appropriately for your FLX's mounting · Wrench sized appropriately for conduit connections · Thread tape or sealant compound for threaded connections Installation Notes · Do not locate the FLX series sensor near inlets/outlets. · If there is surface wave action, then use a time-delay relay or stilling tube. If a stilling tube is used, drill vent holes in the tube and use a spacer to assure the float has free travel inside the tube (See Figure 2.1). · The FLX can be mounted up to 30° from vertical. Inflow Stilling Tube Inflow 30° 30° Spacer 30° Figure 2.1 Mounting Instructions Flange Mounting Provide the compatible mating flange on the tank and install using a suitable gasket. Plug Mounting Provide the compatible female boss on the tank and install the FLX with a suitable gasket, O-ring, or thread tape. 5 Electrical Installation DANGER: Do not remove the housing cover until the atmosphere is determined safe, and the power supply is turned off. · Install conduit and/or cable with necessary seal(s) per Drawing 9003281. · Remove housing cover. · Check the Wire Color Diagrams and Table on page 4 before making any connections. · Connect the wire(s) for your system to the appropriate terminal for each switch. · Replace housing cover. · For inductive loads or high-voltage/high-current resistive loads, provide circuit protection for switch(es) (See Figure 2.2). See Specifications on page 2 for switch ratings. Circuit protection must be located in non-hazardous areas. Protecting Circuit Using Diode Protecting Circuit Using Varistor Protecting Circuit Using CR E L R C Figure 2.2 C = 2I/10 (uF) R = Approx. 10 x I E (I + 50/E) IMPORTANT: DO NOT EXCEED CONTACT RATINGS! A back electromotive force of several hundred volts (energy stored in the inductance) arises when the contacts are opened under inductive loads or high-voltage/high-current resistive loads. This results in considerable decrease in contact life. IMPORTANT: Your FLX MUST be installed according to drawing 9003281 (FLX Hazardous Location Mounting) to meet listed approvals. Faulty installation will invalidate all safety approvals and ratings. Removal Instructions Removing your FLX from service must be done with care. · Ensure all switch circuits are de-energized. · Disconnect all switch circuits. · Remove the FLX with an appropriately sized wrench (per your mounting type). · Clean the FLX's stem and floats of any debris (see General Care) and inspect for damage. · Store your FLX in a dry place, at a temperature between -40° and 40°C (-40° and 104°F). 6 CHAPTER 3: MAINTENANCE General Care Your FLX series stem-mounted multi-point float switch is very low maintenance and will need little care as long as it is installed correctly. However, in general, you should: · Periodically inspect the stem and floats for any trapped debris, sediment, or other foreign material. · Avoid applications for which the FLX was not designed, such as extreme temperatures, contact with incompatible corrosive chemicals, or other damaging environments. · If your FLX has an NPT mount, inspect the threads whenever you remove it from duty or change its location. IMPORTANT: The switch points on an FLX CANNOT be moved, changed, or adjusted. 7 1 0 2 5 W e s t 1 7 0 0 N o rth L o g a n , U ta h U S A 8 8 8 .5 2 5 .7 3 0 0 A u to m a tio n P r o d u c ts G r o u p , In c .
