P108 Far Blanking Distance
This is the distance (as a percentage of empty level P105 ) beyond the
empty point that the unit will be able to measure, and by default is pre-set to
20% of the empty level.
If the surface being monitored can extend beyond the Empty Level ( P105 )
then the far blanking distance can be increased to a maximum of 100% of
empty level.
This parameter is always entered as a % of empty level.
mA Input
The 4-20 mA (Auxiliary) input is available as an option (Consult Pulsar for
details of availability), and can be used to replace the transducer for
applications where an ultrasonic transducer cannot be used.
P119 mA Status
If P101 (Xducer) = 1 (Auxiliary)
This indicates the current status of the Auxiliary input if selected
Option Description
0 = mA OK (Default)
mA input present and functioning correctly
1 = mA Open No input (device) is being detected
2 = mA Short Input is indicating a fault condition
P120 Low mA in
This parameter sets the current input figure that is used to represent empty
when using the optional current input, instead of an ultrasonic transducer.
Default = 4ma
P121 High mA in
This parameter sets the current input figure that is used to represent span
when using the optional current input, instead of an ultrasonic transducer.
Default= 20mA
P122 Low Level in.
This parameter sets the distance to empty point when using the optional
current input, (Aux. input) instead of an ultrasonic transducer.
