Figure 28 mA Output in Cranes
The aout_map with setting 2 is for getting the wind speed value and the alarm signal. The
wind speed value in the Aout1 channel activates the wind speed alarm when the wind speed
value exceeds the set limit value.
s aout_map,2
The analog output 2 works as digital output. aout2_o sets the threshold wind speed
(ws_tresh, unit [m/s]) to 20 m/s:
s aout2_o,20
s aout2_g,1
To invert the logic signal, type:
s aout2_g,-1.
aout1 gives wind speed 4 … 20 mA output. aout2 gives 0 mA when the wind speed is <
20m/s, otherwise 20 mA.
