Often you will however make the zero angle calibration of the CAN azimuth or rudder transmitter (encoder) instead;
it is always good praxis to adjust or calibrate the data source if possible.
To zero-adjust DEIF RTC 300 or RTC 600 angle transmitters, please see the quick start guide or the detailed
installation instructions.
Alternatively,
select “Enter value manually…” by highlighting and pressing OK.
This function can be used if it is not possible to physically set the azimuth at 0 degree, but the offset between
physical and transmitter zero is known.
Direction:
makes it possible to change the measuring direction of the angle transmitter (encoder) between
clockwise (CW) and counter clockwise (CCW). In praxis, the sign of the absolute angle will be shifted. This is very
useful if the angle transmitter is mounted upside-down.
Either set the azimuth physically to 0
degree and press OK to accept the actual
value as the new zero reference input
value, for example 255 as shown in this
case, press OK when “Use actual input
value:” is highlighted to accept that actual
value 255 is set up as the new zero
reference.
Please note that it may take a few
seconds before the actual value is
updated.
Use the softkeys to enter a new zero
reference value. The actual parameter
value is also presented in this case for
information. This is sometimes very useful
when a new value must be entered.
Please be aware, that the min/max values
that the “value input tool” handles
exceed the relevant input values for this
data type. In this example, using a signed
16 bit, all values above +32767 are not
relevant.
