8.2. Basic settings
The first start-up requires you to make the basic configuration (i.e. setting the type of level meter,
measuring range and threshold levels needed for switching the respective relays).
If possible, switch off the controlled equipment as long as you are setting up the device.
Setting up the measuring input for the level meter
The setting defines the type of the current or voltage input, filtration, decimal point position, measur-
ing range and extension of the nominal range.
•
Type of the input / sensor "tYPE"
This parameter can be set to values:
0-20, 4-20
- current inputs.
0-10, 2-10, 0-5, 1-5
- voltage inputs.
Entering and controlling the menu
To enter main menu (being in the measurement mode) operator must to press and hold at least 2
sec.
[ESC/MENU]
button. If numerical parameter is being edited, a short press of
[ENTER]
button
change edited position. A long press of
[ENTER]
button (at lest 2 sec.) causes of display a
”SEt?”
ask, which allow user to make sure if change of the parameter value is correct. If switch parameter
is being edited, a short press of
[ENTER]
button causes of display a
”SEt?”
ask. When
[ENTER]
button is pressed again (while
”SEt?”
is displayed) the new value of the parameter is stored in
EEPROM memory.
If some password different from „0000” is set, then every enter to main menu follows the entering
of password. If entered password is correct then first menu position will be displayed else warning
”Err”, and unit returns to measurement mode.
•
Filtration rate "FiLt"
If the parameter Filtration is set to maximum values and the input current of the level meter
is dropping (rising), the resulting measurement value will change slowly.
It can be set to values from 0 (no filtration ) to 5.
0
= no filtration (OFF)
5
= maximal filtration
After turning the power supply on, device ID and software version are showed on the display, next
the controller goes to the measurement mode.
If no button is pressed within 1 minute, the unit automatically switches back to the measuring mode.
