Pulse output (available only for DO1, DO2):
Pulse rate:
Max 10kHz (10,000pps) (DO1)
Max 100Hz ( 100pps) (DO2)
(Over 1kpps, auto-setting)
Pulse width:
0.3 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 (Note1):
High, High-high, Low, and/or Low-low alarm
Empty pipe alarm output (Note2):
Preset count output:
Converter failure alarm output (Note2):
Note1: Two outputs (DO1 and DO2) are
needed for 4-range switching and
forward/reverse 2-range switching.
Note2: 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.

dot-matrix
128×128
(back-light provided)
Parameter setting:
Parameters can be set as follows:
IR Switches:
Tree
key
switches
configuration parameters.
Digital communication:
The AF900 hand-held terminal or PROFIBUS,
Modbus is needed to set parameters.
Zero adjustment:
Zero point adjustment can be started by pressing
the switch in the converter.
Damping:
0.5, 1 to 60 seconds (selectable in one second
increments)
Zero and span calibration:
Built-in calibration signal source allows converter
unit check.
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
Communication: No communication
