Rev. C4, 10/09 • FLX Series Warranty and Warranty Restrictions APG warrants its products to be free from defects of material and workmanship and will, without charge, replace or repair any equipment found defective upon inspection at its factory, provided the equipment has been returned, transportation prepaid, within 24 months from date of shipment from factory.
FLX Series Rev. C4, 10/09 • Description The FLX series instruments contain reed switches in the stem and permanent magnets in the floats. As the float rises or falls with the level of the liquid, the magnet inside the float act on the reed switch inside the stem to provide the SPST switching action. Stem Reed Switch Permanent Magnet Float Float Travel-Stop • Handling of the Explosion-Proof FLX Series The FLX is rated CSA Class 1 Division 1; Groups C, D for explosive environments.
Rev. C4, 10/09 • FLX Series Installation - Unpacking When unpacking the instrument, exercise care not to subject the instrument to mechanical shock. After unpacking, visually inspect the instrument for damage. - Environment The FLX series sensors should be installed indoors or outdoors in an area which meets the following conditions: 1. The ambient temperature does not exceed -400F to +1850F (-400C to 850C).
FLX Series Rev. C4, 10/09 • Installation - Location 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. Wave action may cause switch to chatter. Use a stilling tube or time-delay relay to prevent switch chatter. - Mounting The FLX can be mounted up to 300 from vertical. 1.

Rev. C4, 10/09 FLX Series • Circuit Protection WARNING! DO NOT EXCEED CONTACT RATINGS! When an inductive load is used (e.g. a motor, a coil, or an electromagnetic relay), a back electromotive force of several hundred volts (energy stored in the inductance) arises when the contacts are opened. This results in considerable decrease in contact life. The same result arises even when a resistive load is used with a high voltage or a large current.
FLX Series Rev. C4, 10/09 • Inspection and Maintenance Periodic inspection is necessary to keep your FLX unit in good working order. CAUTION! Do not remove the housing cover until the atmosphere is determined to be safe, and the power supplied to the unit is turned off. 1. Keep the sensor clean. Never leave the housing cover off. If the cover becomes damaged or is misplaced, order a replacement immediately.
