Input Settings Menus (cont’d)

Data From (certain menu items only show up depending on the input type)
o Source determines the type of sensor installed in the detector. E.g. bridge,
electrochemical, etc.
o Remote Sensor set to Yes indicates that the sensor is installed remotely with Remote
sensor option.
o Min and Max Raw set the range of the input to the A/D converter. Normally set to
800/4000. Useful when the sensor’s output doesn’t provide a full range signal.
o
Remote ID is where the Modbus slave’s ID number is entered
o Alias is the register number which defines the location of the variable representing the
input value of the Modbus data received through the communication ports
o Interface assigns which communication port the Modbus slave is connected to and the
detector will get its data from
o
Filter (second)
sets the number of seconds over which samples are averaged
o
Byte Order determines WORD and BYTE alignment of data at the remote Modbus
transmitter when sending this 4-byte IEEE floating point values
o Polarity determines the polarity of the sensor
o
Heater Enabled
determines if the sensor heater is turned on or off
o
Heat (degC) is the thermostat setting of the sensor
o Set Voltage set’s the voltage being supplied to bridge type sensors
o Set Balance adjusts the balance of a catalytic bead sensor and must only be adjusted
with ZERO gas on the sensor.
o Set PGA is the adjustment that matches the input signal range to the detectors input
signal conditioning circuits.
o
Marker used to detect special modes of operation from analog inputs, which some
monitors use to indicate special modes of operation, such as calibration mode

Configure
o
Tag
is a 16-character ASCII field typically used to describe the monitored point by user
tag number or other familiar terminology.
o E. Units or engineering units may have up to 10 ASCII characters, and is usually factory
configured based on sensor type.
o Zero defines the reading to be displayed when the output is 4mA (0%)
o Span defines the reading to be displayed when 20mA (100%) is the output.
o Decimal Points sets the resolution of the displayed reading, and may best to zero, one
or two.
o Block Negative blocks negative values from being display (Displays 0).
o Deadband (%) allows forcing low values to continue to read zero. This is useful when
there are small amounts of background gases that cause fluctuating readouts above
zero. The highest amount of Deadband allowed is 5%. Note: Deadband affects all
outputs as well as the local reading.
o Warmup (m) defines the time allotted for sensor warmup. During this time output s will
be held at a zero value and relays will stay in their normal state.
o Cal Purge (m) determines the amount of time the transmitter will stay in calibration
mode after calibration is complete as the sensor returns to normal state.

Calibration
o Zero Setpoint is set to the zero value.
o Span Setpoint is set to the calibration gas value, typically 50% of full scale.
o Cal Gain reflects the change made when calibrating.
o Gain Offset reflects the change made when calibrating.
o Gain Unity is to reset the Gain and Offset back to default (1 and 0 respectively)
o Calibrate is used to calibrate sensors.

Temp Comp allows the user to adjust the gain and offset that is applied to sensors to
compensate for temperature drift. Factory supplied sensors are preprogrammed with
these values which are automatically uploaded from the Smart Sensor.
