Hint:
Protections on binary and three state inputs are following:
IL-CU: AI1 Shutdown IG-IOM: AI1 Shutdown
AI2 Shutdown AI2 Shutdown
AI3 Warning AI3 Shutdown
AI4 Shutdown
Unused analog inputs
Configure Type = Not used
Example of analog input configuration
Configure Oil press input for measuring in Bar, VDO oil pressure sensor, range 0 to 10.0 bars. Alarm
protection level set to 3.5 bars, shut down level 1.2 bars.
Start LiteEdit and select – Controller - Configuration – Modify – Oil Press.
Set configuration for Oil Press analog input:
Type: selection between Not used and Alarm
“Not used” – analog input isn’t used
”Alarm” – analog input is used
Set to: Alarm
Config: selection between Analog, Binary Tri-state input.
“Analog” – resistor sensor is connected to Analog input.
“Binary” – open/close contact is connected between Analog input and COM terminal of Analog inputs.
Analog input detects only open/close state.
“Tri-state” – open/close contact is connected parallel to one of two serial resistors between Analog
input and COM terminal of Analog inputs.
Set to: Analog
Dim: Physical dimension of measured value (°C, %, Bar, ..) Maximal dimension length is three
characters.
Set to: Bar
Contact type: selection of polarity only when analog input is configured as Binary or Tri-state. When
is analog input configured as analog this setting has no sense.
„NC“ – polarity of binary or tri-state input
„NO“ – polarity of binary or tri-state input
Sensor: selection of sensor characteristic
„Unused input“ - when Analog input is not used. On the InteliLite screen is displayed „####“ value, no
alarm is detected.
„Curve A“ – User curve A is defined in LiteEdit (default VDO temperature sensor)
„Curve B“ – User curve B is defined in LiteEdit (default VDO pressure sensor)
„Curve C“ – User curve C is defined in LiteEdit (default VDO fuel level sensor)
„Pt1000“ – PT1000 sensor characteristic according to IEC 751
„Ni1000“ – Ni1000 sensor characteristic according to DIN 43 760
„VDO temp“ – VDO temperature sensor
„VDO press“ – VDO pressure sensor
„VDO level“ – VDO level sensor
„4-20mA/60“ – current output sensor characteristic – requires external resistor 120 ohms between
Analog input and COM terminal of Analog inputs
„4-20mA/100“ – current output sensor characteristic – requires external resistor 120 ohms between
Analog input and COM terminal of Analog inputs
Set to: VDO press
Decimals: setting of number of decimal points of measured value.
„0“ - e.g. 360 kPa, 100%, 50 °C
„1“ – e.g. 3.6 Bar
