Start-up
5.1 Start-up
Start-up of the device begins when power is supplied. While a self-test is being performed, it
may take up to 30 seconds for the sensor to initialize and be identified. Changes to the settings
can not be made until the converter has recognized the sensor. When recognized, the sensor will
appear in the display mode.
If the self-test indicates that the internal clock has been without electric power for a period of
time, the unit goes to a menu for setting date and time. After this setting is complete, the display
mode shows the sensors in the order in which they were tagged or the slot number.
5.2 Connect sensors
When the converter detects a new sensor an identification process is started, indicated by a
rotating line between the header and the time on the first line of the display. Once the sensor is
identified, the converter asks how it shall be used. Default choice is to connect the sensor to an
empty slot from a list of free slots. If no slot is free, a message saying so will be displayed. Slots
with no sensor currently connected can be freed in the converter menu. If a sensor is added to
slot 1 or 2, the converter will ask if the corresponding 4...20 mA output shall be used (unless it is
already used by another sensor). The use of an output can be changed in the sensor setting
menu.
If an identical sensor has been connected, but is currently not, the slot of this sensor can be
reused. The new sensor inherits most of the configuration and calibration of the old sensor. This
function is intended to quickly get up and running when a sensor is replaced. The inherited
calibration will not be perfect since it’s done for another sensor, but it will be closer than the
factory default. Some sensor types can not reuse slots.
How to get started:
• Press ↑ and ^ simultaneously for 5 seconds.
i The converter menu opens.
• Select "Settings" and confirm by pressing ^.
• Set the different parameters for the converter in this menu.
• Press ↑ and ^ simultaneously to return to the main menu.
• Connect the sensors, let the converter identify them, and assign slots for them.
• Select the sensor you want to setup using ↓ and ↑.
• Press ^ for 5 seconds.
i The sensor menu for the selected sensor opens.
• Select "Settings", insert the appropriate values for the sensor selected. Then select the first
line and press ^ to return to the sensor menu.
• If automatic cleaning is used, select "Cleaning" and enter the parameters. Then select the first
line and press ^ to return to the sensor menu.
• Select "Scale" then insert the appropriate values for the sensor selected. "Min." and "Max."
refers to the measured value required for 4 and 20 mA output.
• Select "Calibrate". Calibrate each sensor according to the sensor manual.
• Press ↑ and ^ simultaneously to return to the main menu.
• Repeat the sensor configuration for all attached sensors.
