"Contact Output Function" Continued
2 Empty detection function
When the detector becomes empty of the measured fluid, the respective
output signals will be as follows.
Output signal
Status
When the detector is empty of fluid
Analog output 4 - 20 mA DC 4mA DC
Pulse output 0%
Contact output
Abnormal status (Open/closed can be freely
selected.)
However, this function can be used when the conductivity is 150 µS/cm
(equivalent to that of water) or higher. The empty detection function
selector switch determines whether this function is activated or not.
(The empty detection function is set to "NOT activated" at shipment.)
Note: Using the empty detection function with a conductivity of 150 µS/cm
or less will cause a measurement error (minus).
2: Range switching output
The contact output status at shipment is as follows.
Range No.1 or normal direction: Open
Range No.2 or reverse direction: Closed
Reverse setting is also possible.
3: Counter preset status output
Activated when the counter reaches the preset value.
4: Self-check result output
Activated only when a self-diagnostic abnormality occurs in the alarm
contact output of code 1.
5: Empty detection function
Activated only when an empty status is detected in the alarm contact
output of code 1.
6: High/low limit alarm
Activated only when a high/low limit alarm occurs in the alarm contact
output of code 1.
7: Alarm contact output and range switching output (2-contact output)
The alarm contact output can be set to ST.OUT1 and the range switch-
ing output to ST.OUT2.
8: Self-diagnostic result output and range switching output (2-contact out-
put)
The self-diagnostic result output can be set to ST.OUT1 and the range
switching output to ST.OUT2.
9: Empty detection function and range switching output (2-contact output)
The empty status detection output can be set to ST.OUT1 and the range
switching output to ST.OUT2.
