State Measurement value output voltage
In normal measurement Voltage corresponding to measured pressure
At above measurement higher limit 9.9V or higher
At below measurement lower limit 0.5 V or less
When filament is OFF 9.9 V or higher
12.6.2.
Filament ON signal
Signal that turns on the filament. To turn on the filament, connect it to GND with the external
switch. In the case of front panel operation or RS485 communication setting, input of this signal
will be invalid.
12.6.3.
Degas ON signal
Signal that turns on degassing. To turn it on, connect it to GND with the external switch. In the
case of front panel operation or RS485 communication setting, input of this signal will be invalid.
12.6.4.
Filament 1/2 changeover signal
Signal that changes over filament 1/2. To change it over to filament 2, connect it to GND. In
the case of front panel operation or RS485 communication setting, input of this signal will be
invalid.
12.6.5.
Pressure protection signal
If the sensor unit exceeds the higher limit of measurement pressure, pressure protection will be
actuated. If it is actuated, the open collector will be Lo output.
Photocoupler rating: 30V
MAX
, 50mA
MAX
, 70 mW
For more information about pressure protection and actions in case of pressure protection signal
being turned ON, refer to the sensor unit manual.
12.6.6.
Emission valid signal
When the emission current is flowing normally or not is output as a signal. If emission current
is flowing normally, the open collector will be Lo output.
Photocoupler rating: 30V
MAX
, 50mA
MAX
, 70 mW
For more information about the emission valid signal and corrective actions in case when the
emission valid signal is turned off, refer to the sensor unit manual.
