Toshiba tic-lf414c Manuel D’Utilisation

Signal type:  20 to 30Vdc voltage signal 
Input resistance: 2.7k

Ω 

Number of inputs: one point 

DI function — One of the following functions can be 

assigned to the optional DI signal. 

Range switching — Selects either the higher or 

lower range in the unidirectional or bidirectional 
2-range setting. 

Totalizer control — Starts and stops the built-in 

totalizer. 

Fixed-value outputs —Outputs fixed-values for 

current and pulse outputs. 

Zero adjustment — Executes zero adjustment 

(on-stream at zero flow rate). 

4–20mAdc (load resistance 0 to 750

Ω) 

Note: The current output cannot be used with the 

PROFIBUS-PA communication. 

Digital outputs — One point (std.) and one more 

point is optionally available as follows. 

Output type: Transistor open collector 
Number of outputs: One point 
Output capacity: 30Vdc, 200mA maximum 

Output type:  

Solid-state relay output (non polarity) 

Number of outputs: One point 
Output capacity: 150Vdc, 150mA maximum  

or 150Vac (peak to peak), 100mA maximum 

DO1 and DO2 functions — One of the following 

functions can be assigned to DO1 (std.) and/or 
DO2 (opt.) 

• Pulse output (available only for DO1, DO2) 

Pulse rate: 3.6 to 36,000,000 pulses/hr (DO1) 

3.6 to 360,000 pulses/hr (DO2) 

(Over 3,600,000 pulses/hr, auto-setting) 

Pulse width: 0.5 to 500ms (but less than half of 
the period for 100% flow rate) 

Note: The same and simultaneous  pulse is not 

available between DO1 and DO2.) 

• Multi-range selection outputs (Note 1) 
• High, High high, Low, and/or Low low alarm 

• Empty pipe alarm output 
• Digital Output Active Status (DO1 and DO2) 

Note 1: Two outputs (DO1 and DO2) are needed for 

4-range switching and forward/reverse 2-range 
switching. 

Note 2:  Normal Open (default set) or Normal Close is 

selected for alarm outputs when programming. 
When power failure occurs, unit will be fault to 
Normal Open. 

• HART (std.) — Digital signal is superimposed on 

4–20mAdc current signal as follows: 
Conforms to HART protocol 
Load resistance: 240 to 750

Ω 

Load capacitance: 0.25µF maximum 
Load inductance: 4mH maximum 

Protocol: PROFIBUS-PA 
Baud rate: 31.25kbps 
Bus voltage: 9-30VDC 

Consumption electric current of bus: less than 16mA 

Manufacture Ident-No.: 093B

Standard Ident-No.: 9740

HEX

 

Slave address: 0-126 (Default address is 126) 
Profile: Profile Ver.3.01 for Process Control 

Devices 

Function blocks: AI(Flow)×1 , Totalizer×1 

Full dot-matrix 128×128 dot LCD display 
(back–light provided) 
The data on the LCD inside the converter can rotate 
to 90, 180, and 270 degrees by a software, without 
rotating the indicator itself. (Combined type only) 

Parameter settings — Parameters can be set as 

follows: 
• IR Switches: Three key switches are provided to 

set configuration parameters.  

• Digital communication: The AF900 hand-held 

 terminal or PROFIBUS   is needed to set 

parameters. 

• Zero adjustment: Zero point adjustment can be 

started by pressing the switch in the converter. 

• Damping: 0.5 to 60 seconds (selectable in one 

second increments) 

 – Toshiba’s 

Zero span calibration tool allows unit to be 
re-calibrated and verified using an internal 
software program (For more information contact
