TIC-LF232A

Communications signal:

A digital communications (HART protocol) signal is superimposed on 4 to 20 mA dc analog output signal.

Load resistance: 240 Ω to 1 kΩ

Load capacitance: 0.25 µF or less

Load inductance: 4mH or less

(For maximum cable length, about 2km is a guideline length when CVV-S 1.25mm2 is used under standard installation condition.)

Note: HART (Highway Addressable Remote Trans-ducer) is a communications protocol for industrial sensors recommended by the HCF (HART Commu-nication Foundation).

Output display:

16-character×2-line dot-matrix LCD

(With back light).

2 units can be selected from the flowing units: flow velocity, instantaneous flow rate, total flow (forward/reverse/difference flow), total count, %, custom unit.

Parameter settings—Parameters can be set as follows

IR Switches: Various parameters can be set without opening the converter housing using 4 infrared switches (password can be set)

•Zero adjustment: Zero point adjustment can be started by pressing the switch in the converter.

Digital communication: The AF 900 hand-held terminal is needed to set parameters.

Damping: 0.5 to 60 s (selectable in 1s increments) “Field re-verification”Mag-Prover– Toshiba’s

Zero span calibration tool allows unit to be re-calibrated and verified using internal software program. (For more information contact Toshiba International Corp.)

Conditions when power fails:

Parameter setting values are stored in non-volatile memory and the values will be restored when the power returns to normal condition. The output and display will stay as follows when power fails.

Current output: 0 mA

Digital output: OFF (contact open)

LCD display : No display

Surge protection: Surge protectors are installed in the power supply, excitation circuit, current signal output and digital I/O circuit.

Terminal block structure: 21-pole, screw connection type (M4 screw)

Housing: Aluminum alloy

Coating: Acrylic resin-baked coating, pearl-gray colored

Cable connection ports :

A cable gland is provided for each port.

OD of cable φ11 to 13 mm

Material Nylon 66

G (PF) 1/2 male screws.

Vibration resistance:

No resonance to the following levels of vibration:

10 to 55Hz with amplitude of 0.07mm

Vibration of 30Hz with 29.4 m/s2 in 4h in each direction will not cause any defect to unit.

Note: If the flowmeter is intended to be used in a location where vibration is applied constantly contact Toshiba.

TIC-LF232A specifications

The Toshiba TIC-LF232A is an advanced inverter air conditioning system designed to optimize energy efficiency while delivering outstanding cooling performance. As part of Toshiba's commitment to innovation and sustainable technology, this model incorporates some of the latest advancements in climate control engineering.

One of the standout features of the TIC-LF232A is its inverter technology. Unlike traditional air conditioning systems that operate on a fixed speed, the inverter technology allows the compressor to adjust its speed based on the current cooling demand. This results in significant energy savings, as the system can maintain the desired temperature more consistently while using less electricity. This feature also contributes to a quieter operation, with reduced noise levels making it suitable for residential and commercial environments alike.

The TIC-LF232A boasts a high Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER), indicating its ability to deliver effective cooling with minimal energy consumption. The incorporation of eco-friendly refrigerants further emphasizes Toshiba's commitment to environmental sustainability, ensuring that users not only save on energy bills but also reduce their carbon footprint.

In addition to energy efficiency, the TIC-LF232A is equipped with a range of advanced technologies designed to enhance user comfort and convenience. The system features a smart control system that allows users to manage their air conditioning remotely via a mobile app. This feature enables users to set schedules, monitor energy usage, and adjust temperature settings from anywhere, providing maximum flexibility and control.

Another key characteristic of the TIC-LF232A is its multi-zone capability. The system can simultaneously provide cooling to multiple rooms or areas, allowing for customized comfort in different spaces. This is particularly beneficial for larger homes or commercial buildings where individualized climate control is valuable.

The TIC-LF232A also prioritizes air quality with its integrated filtration system. It includes advanced filters that enhance indoor air quality by capturing dust, allergens, and other particles, promoting a healthier living environment.

Overall, the Toshiba TIC-LF232A stands out as a cutting-edge air conditioning solution that combines superior energy efficiency, innovative technologies, and user-centric features, making it a top choice for those seeking reliable and effective climate control solutions.
