© 2005-2016 Nira Control AB 91
Aux Temp
Six temperature inputs, typically used for NTC/PTC type temperature sensors
can be utilized as auxiliary inputs. These are configured using Bv Aux TempX,
where x is an integer between 1 and 6.
Aux Digital Input
Two inputs are available for detection of pulse signals, e.g. from wheel speed
sensors. These are configured in Di Aux1 Teeth and Di Aux2 Teeth.
