SF
6
Sensor Signals
The OPTI
mizer
2
can monitor the signal from two types of
SF
6
density sensor:
Analog Sensors with an output current signal within
the range of 4mA and 20mA
Digital Sensors with a special frequency & pulse-
width-modulated signal (INCON DSDP)
Each of the three input channels can be separately
programmed for an Analog or Digital sensor or disabled
(Off). If the SF
6
Sensor Signal chosen is “Analog”, four
more parameter fields will appear for that sensor (see
below).
Note : When the sensor signal chosen is "Analog", the
chosen units cannot be "Pressure".
Note:
When the
OPTI
mizer
2
is cold-started, the SF
6
Sensor Signal parameters are all set to “Off”, which
disables the inputs.
To set the SF
6
Sensor Signals, select the CONFIGURATION
tab and click “EDIT”:
Under the headings “SF
6
Sensor A”, “SF
6
Sensor B”, “SF
6
Sensor C”:
Program: Signal = “Digital”
or
Signal = “Analog”
Analog Sensor - Signal Low (Milliamps)
Each SF
6
input on the OPTI
mizer
2
can be programmed
to monitor an analog signal with a low scale that may be
something other than 4mA. For example, some sensors
have a working range of 6.5 to 20mA.
Note: When the OPTI
mizer
2
is cold-started, the Signal
Low parameter is set to 4.0mA.
Note: If the measured sensor signal is lower than the
programmed Signal Low value, a “Sensor Signal
Out of Range” alarm will be asserted.
To set the Signal Low parameter, select the
CONFIGURATION tab and click “EDIT”:
Under the headings “SF
6
Sensor A”, “SF
6
Sensor B”, “SF
6
Sensor C”:
Program: Signal Low (mA) = “6.5”
Analog Sensor - Signal Low Represents
(Units)
Each SF
6
input on the OPTI
mizer
2
can be programmed
to scale the analog Signal Low (programmed above) to a
grams per liter value that may be something other than zero.
Note: When the OPTI
mizer
2
is cold-started, the Signal
Low Represents parameter is set to 0.0 g / L.
To set the Signal Low Represents parameter, select the
CONFIGURATION tab and click “EDIT”:
Under the headings “SF
6
Sensor A”, “SF
6
Sensor B”, “SF
6
Sensor C”:
Program: Signal Low Represents (g / L) = “10.0”
Analog Sensor - Signal High (Milliamps)
Each SF
6
input on the OPTI
mizer
2
can be programmed
to monitor an analog signal with a high scale that may be
something other than 20mA.
Note: When the OPTI
mizer
2
is cold-started, the Signal
High parameter is set to 20.0mA.
Note: If the measured sensor signal is higher than the
programmed Signal High value, a “Sensor Signal
Out of Range” alarm will be asserted.
To set the Signal High parameter, select the
CONFIGURATION tab and click “EDIT”:
Under the headings “SF
6
Sensor A”, “SF
6
Sensor B”, “SF
6
Sensor C”:
Program: Signal High (mA) = “16.0”
Analog Sensor - Signal High Represents
(Units)
Each SF
6
input on the
OPTI
mizer
2
can be programmed
to scale the analog Signal High (programmed above) to a
grams per liter value.
Note: When the OPTI
mizer
2
is cold-started, the Signal
High Represents parameter is set to 400.0 g / L.
To set the Signal High Represents parameter, select the
CONFIGURATION tab and click “EDIT”:
Under the headings “SF
6
Sensor A”, “SF
6
Sensor B”, “SF
6
Sensor C”:
Program: Signal High Represents (g / L) = “70.0”
