== External Error Input == | == External Error Input == |
This mode allows the temperature error to be derived | This mode allows the temperature error to be derived from an external temperature transducer. In this mode, the thermistor and associated signal processing electronics are not used. The temperature error is related to the input voltage Vin by: Temperature Error [˚C] = Gain [˚C/V] x Vin + Offset [˚C]. Touch the Settings icon to the right of the channel selection to adjust the Gain and Offset. |
| |
| == Feedforward == |
| This mode allows a feedforward signal to be summed into the output of the PID loop filter. The feedforward signal current is related to the input voltage Vin by: Feedforward Current [A] = Gain[A/V] x Vin + Offset[A]. Touch the Settings icon to the right of the channel selection to adjust the Gain and Offset. |

Similarly, you can program output values. If you select <color magenta>Channel 1 Output</color> from <imgref io> you will be presented with <imgref out_prog>. You can choose any value from <tabref output> to be delivered to the <color magenta>Channel 1 Output</color> output on the front panel. | Similarly, you can program the output signals for the Output Channels 1 and 2. For each channel, the actual (measured) temperature, the temperature error, or the current output can be chosen as the output signal. For instance, if you select <color magenta>Channel 1 Output</color> from <imgref io> you will be presented with <imgref out_prog>. You can choose any value from <tabref output> to be delivered to the <color magenta>Channel 1 Output</color> output on the front panel. Touch the Settings icon to the right of the channel selection to adjust the Gain and Offset for these output signals as in <imgref out_gain>. When porting the Temperature of a given loop to an Output, setting the Gain equal to 0.1 V/°C and the offset to 0 V will give a convenient 2 V output at 20°C. |
