LCD display:
Full dot-matrix 128×128 dot LCD display
(back–light provided)
A parameter change will rotate the display.
Parameter settings — Parameters can be set as
follows:
• IR Switches: Three key switches are provided
to set configuration parameters.
• Digital communication: HART, PROFIBUS
or Modbus is needed to set parameters.
• Zero adjustment: Zero point adjustment can
be started by pressing the switch in the
converter.
• Damping: 0.1 to 60 seconds (selectable in one
second increments)
“Field re-verification”
Mag-Prover– Toshiba’s
Zero span calibration tool allows unit to be
re-calibrated and verified using an 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 outputs and
display will remain as follows when power fails.
• Current output: 0mAdc
• Digital output: OFF
• LCD display: No display
• HART: No communication
• PROFIBUS: No communication
• Modbus: No communication
Power supply:
One of the following can be selected:
• 100 to 240Vac, 50/60Hz
(allowable voltage 80 to 264Vac)
110Vdc
(allowable voltage 90 to 130Vdc)
• 24Vdc (allowable voltage 18 to 36Vdc)
Surge protection:
Arresters are installed in the power supply and a
current signal output circuit to help protect the meter
from lightning and improve personnel safety.
Case: Aluminum alloy (equal to IP 67)
Coating:
Acrylic resin-baked coating, pearl–gray colored
Cable connection port:
Cable glands —
LF620 and LF622 without cFMus Approval:
Provided as standard, outer diameter of cable
11~13mm
Material Nylon 66
G (PF) 1/2 male threads.
LF620F and LF622F with cFMus Approval:
Not provided, 1/2–14NPT male threads are
required.
Applicable diameter —
0.433 to 0.512 inch (11 to 13mm)
Note: When PROFIBUS option is specified, cable gland size is
6 8mm for signal cable, 11 13mm for power
cable
Vibration resistance:
No resonance to the following levels of vibration:
• 10 to 150Hz with acceleration of 9.8m/s
2
• Vibration of 30Hz with 29.4 m/s
2
in 4h in each
direction will not cause any defect to unit.
Note: Avoid using the flowmeter in an environment with
constant vibration.
