T8 Analog Input 3 Thermistor Feedback (F62) shows the measured resistance.
If a KTY84, PT100, PT1000 or PT2000 type device is selected for temperature feedback then T8 Analog Input 3 Thermistor Temperature (F63) shows
the temperature of the device based on the resistance to temperature characteristic specified for this device. Otherwise T8 Analog Input 3 Thermistor
Temperature (F63) = 0.0.
T9 Analog Output 1 Source (F64) defines the source parameter for analog output 1. The value of the source parameter is scaled with T9 Analog
Output 1 Scaling (F65) and if the scaling is greater than 1.000 the value is clamped between -100 % and +100 % or between 0 % and 100 %
depending on whether the output is bipolar or unipolar. The resulting value is then used to control the output. It should be noted that the normal rules
for parameter routing do not apply, but the scaling always makes -100 % to +100 % correspond to the range from minus source parameter maximum
to plus source parameter maximum, and 0 % corresponds to the source parameter value of zero. This means for example that a parameter with a
minimum of 1 and a maximum of 10 will produce an output that changes from 10 % to 100 % as the parameter is change from minimum to maximum.
The outputs provided with different hardware are given in the table below.
The output mode is defined by T9 Analog Output 1 Mode (AU21) as shown in the table below.
See T9 Analog Output 1 Source (F64).
