IL-NT-AMF-2.2-Reference Guide.pdf
Switchboard lighting strike protection according standard regulation is expected
for all 4 connection
types!!!
Hint:
Phase sequence check is not possible to evaluate under voltage 50V what causes that if measured
voltage 50V is within the allowed range, controller will not allow to close the GCB, even if relevant LED
diode on front panel of IL-NT lits.
Analog inputs
Three analog inputs are available on the IL-NT. First analog input is fixed to be used for engine Oil
Pressure.
Configuration
Each analog input can be configured by LiteEdit software in following way (First analog input is
dedicated to engine Oil pressure).
