Permanent Magnet
Float Travel-Stop
Float
Stem
Reed Switch
• 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.
• Handling of the Explosion-Proof FLX Series
The FLX is rated CSA Class 1 Division 1; Groups C, D for explosive environments. All repairs and adjustments of the FLX must be made by the factory. To modify, disassemble, or alter the FLX on site is strictly prohibited. Do not loosen any joints, with the exception of the housing cover for electrical connection.

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). NOTE: It is recommended that a sun shield be installed over the housing if exposed to direct sunlight.
2. The medium temperature does not exceed -400F to +1850F (-400C to 850C).
3. Relative humidity up to 100%
4. Pollution Degree 2
5. Measurment Category II
6. Altitude 2000 m or less.
7. Locate the sensor away from strong magnetic fields such as those produced by motors, transformers, solenoid valves, etc.
8. The medium is free from metallic substances and other foreign matter.
9. No corrosive gases such as NH3, SO2, Cl2, etc.
10. No excessive vibration
11. Ample space for maintenance and inspection.

• 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. Flange Mounting Provide the compatible mating flange on the tank and install using a suitable gasket.
2. Plug Mounting Provide the compatible female boss on the tank and install the FLX with a suitable gasket, O-ring, or thread tape.

• Circuit Protection
W ARNING!
DO NOT EXCEED CONT ACT RA TINGS! 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. The figures below show circuits for protecting the reed switch(s) from the back electromotive force.
Code A & B Switches
Max. contact capacity 70 VA AC, Max. switching current 220 VAC 0.5 A, 120 VDC 0.5 A
Code C Switches
Max. contact capacity 110 VA AC, Max. switching current 220 VAC 0.5 A, 115 VDC 0.5 A

• 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 .
If sediment or other foreign matter is trapped between the stem
and the float, detection errors may be caused. Keep the float and
stem clean.
2. Inspect the switches and terminals.
• T echnical Notes
1. The float travel stop settings are based on how the magnetic field influences the reed switch. Normally it is not necessary to move the stop. If the stops are moved, check the switch action for float overrun.
2. Normally Open (NO) (switch closes as level rises) and Normally Closed (NC) (switch closes as level falls).
