As three state input
Open, close and failure state are detected. Threshold level is 750
, failure is detected when circuit
resistance is <10
or > 2400
.
Hint:
Protections on binary and three state inputs are following:

Unused analog inputs
Configure Type = Not used
Example of analog input configuration
Configure Engine Temp input for measuring in °C, VDO 40-120°C sensor, range -16 to 120 °C. Alarm
protection level set to 90 °C, shut down level 110 °C.
Start LiteEdit and select
– Controller - Configuration – Modify – Engine Temp.
Set configuration for Engine temp analog input:
Type
: Selection between Not used and Alarm
“Not used” – analog input isn’t used
”Alarm” – analog input is used
Set to:
Alarm
Name
: Name of the analog input. Maximally 14 letters.
Set to:
Engine Temp
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
Alarm Properties
: Selection between different direction of protection
– Under Limit, Over Limit or
combination with Fail sensor.
“Engine running only” – check this setting if you wish to active protection on analog input only while
engine is running, not, when it stops.
Set to:
Over Limit
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.
Default user curves predefined on AI1
– AI3:
„VDO 10 Bar“ – VDO pressure sensor
„VDO 40-120 °C“ – VDO temperature sensor
„VDO level %“ – VDO level sensor
Set to:
VDO 40-
120 °C
When you choose the predefined or user curve the Sensor Name, Dim and Resolution are set
automatically according to curve, user modification is possible.
