Johnson Controls F61TB-9100 Flow Switch User Manual

1. ആമുഖവും അവസാനവുംview

The Johnson Controls F61TB-9100 Flow Switch is designed for reliable liquid flow detection in various applications. It is suitable for use with water, sea water, swimming pool water, ethylene glycol, and other liquids that are not harmful to the internal components of the switch. This device features SPDT (Single Pole Double Throw) contacts, allowing it to energize one device and de-energize another from the same power source when the liquid flow rate either exceeds or falls below a predefined set point.

Typical applications include compressor shutdown on liquid chiller systems, proving flow on electric immersion heaters, and providing signals or alarms when a condenser pump in a cooling system shuts down. The F61TB-9100 is a pipe-insert type flow switch, designed for easy mounting on top of the liquid line.

• Ensure the liquid in the pipe is compatible with the brass contact material and other internal components of the switch.
• Do not exceed the maximum liquid pressure of 20 Bar.
• Verify that the paddle does not touch the pipe or any other obstruction within the pipe to ensure accurate flow detection.
• Protect the device from physical damage during installation and operation.

4.1 മൗണ്ടിംഗ്

The F61TB-9100 is a pipe-insert type flow switch. It must be mounted on top of the liquid line. Ensure the arrow on the switch body points in the direction of the liquid flow. Proper orientation is critical for accurate operation.

Figure 1: Johnson Controls F61TB-9100 Flow Switch. This image shows the compact black housing with the brass pipe insert and the flow-sensing paddle extending from it. The threaded brass section is designed for direct insertion into a pipe, and the black housing contains the electrical connections and adjustment mechanism.

4.2 ഇലക്ട്രിക്കൽ വയറിംഗ്

The switch features SPDT contacts. Wiring connections are made via screw terminals, which can accommodate wires from 1 to 2.5 mm². Refer to the specific wiring diagram provided with your unit for correct connection to your control system. Ensure all wiring complies with local electrical codes.

4.3 ഫ്ലോ റേറ്റ് ക്രമീകരണം

The F61TB-9100 is factory set at a minimal flow setting. If a higher flow rate is required for activation, the setting can be adjusted. To increase the required flow rate, turn the adjusting screw clockwise. This screw is located under the cover of the switch. Always ensure the system is depressurized and power is disconnected before making adjustments.

5. ഓപ്പറേഷൻ

The F61TB-9100 operates by detecting the presence or absence of liquid flow. When liquid flows through the pipe at or above the set flow rate, the internal paddle is displaced, activating the SPDT switch contacts. Conversely, when the flow drops below the set rate, the paddle returns to its resting position, de-activating the contacts.

The SPDT contacts allow for flexible control: one circuit can be energized while another is de-energized, or vice-versa, based on the flow condition. This makes it suitable for various control and alarm functions.

6. പരിപാലനം

The Johnson Controls F61TB-9100 Flow Switch is designed for minimal maintenance. However, periodic checks are recommended to ensure continued reliable operation:

• വിഷ്വൽ പരിശോധന: Regularly inspect the switch for any signs of physical damage, corrosion, or leaks around the pipe connection.
• Paddle Clearance: Ensure the paddle remains free from obstructions within the pipe. Accumulation of debris can impede its movement and affect accuracy.
• ഇലക്ട്രിക്കൽ കണക്ഷനുകൾ: Periodically check that all electrical connections are secure and free from corrosion.
• പ്രവർത്തനക്ഷമത പരിശോധന: If possible and safe to do so, periodically test the switch's operation by varying the flow rate to confirm it activates and de-activates at the desired set points.

CAUTION: Always disconnect power and depressurize the system before performing any maintenance or inspection.
