WIRING OF ANALOG INPUTS-ISOLATED SENSORS
Analog inputs are designed for resistive sensors with resistance in range of 0: to 2,4k:.
To ensure a proper function use shielded cables, especially for length over >3m.
COM terminal is dedicated to measure ground voltage potential difference between engine and
controller.
As binary input
Open, close state are detected, threshold level is 750 :.
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:
IL-NT: 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 Water 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 – Water Temp.
Set configuration for Water 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: Water Temp
