Set the Input Parameters
The input parameters are set in the “Setup/Measure Points” menu.
Three submenus are available: “Information”, “Sensor Data”, and “Alarms”.
Enter user-dependent and system-dependent information in the “Information” menu. Enter the
sensor-dependent parameters in the “Sensor Data” menu, and specify the alarm thresholds and
the alarm behaviour (latching/crossing) in the “Alarms” menu.
Option field: “Measure Point No.”: Use this to select the input to be configured.
NOTE: The Measure point no. (input no.) is assigned within the system to the MAI modules used.
Option field: “Locked”: The input is inhibited (no alarm given).
NOTE: This is to be recommended especially during maintenance work on the sensors while the
alarm devices are still connected (see section 7 Maintenance and Service). Specify the status of
the analog output assigned to the input in the “Signal if Locked” option field of “Setup/System”
menu (“Setup/System Settings”)
Information Menu
Text fields “Tag”, “Marking”, and “Installation Place”:
- Enter customer-specific and system-specific parameters of the input here.
In the text field: “Serial No. Head” (“Serial Number Head”):
- Enter the sensor serial no. of the sensor connected to this input.
Sensor Data Menu
Here is where information specific to the sensor and to measurement gas is entered.
Option field: “Sensor Type” (“Sensor”): Select the MSA sensor type connected to the input.
NOTE: A sensor database is assigned to each type of sensor. This database contains information
such as noise level, minimum signal, etc. In conjunction with the selected measurement gas and
measuring range, a corresponding linearization is also automatically activated when needed as a
function of the type of sensor.
Option field “Dimension”: Select the measurement unit (%LEL, vol.%, ppm, etc.)
Option field “Range” (“Range from 0 to:”): Select the measuring range.
NOTE: Care must be taken to ensure that the selected values are correct and valid.
Option field “Measure Gas”: Select the measurement gas (gas or vapour to be monitored).
Option field “Zero Gas”: Select the zero gas (gas used to adjust the zero point of the sensor)
Option field “Reference Gas”: Select the reference gas (gas used to calibrate the sensitivity of the
sensor when the measurement gas is difficult to handle).
NOTE: If the measurement gas (the gas or vapour to be monitored) is used to check and calibrate
the sensor attached to the input, the same gas as that appearing in the field “Measure Gas” is to
be selected in the option field “Reference Gas”. (In the “Maintain/Calibration” menu, the gas se-
lected in the “Reference Gas” field appears as the test gas.)
