10.5 Analog Inputs
The MCT supports up to 14 analog inputs which are used for remote set point inputs. Each of the available
analog inputs can be configured from the ‘Analog Input’ screen.
The left and right navigation buttons at the upper right of the screen allow the user to scroll through each
available input. To make changes to the analog input’s configuration, select the desired input type by pressing
the voltage (Vdc) or current (mA) button to select a 2-10V or a 4-20mA input signal.
NOTE: If the analog input type is changed from voltage to current or vice versa, power must be cycled to the
MCT controller in order for the input to switch signal types.
Select the desired loop by pressing the ‘Destination’ button to select from the list of available control loops.
Se
lect the desired control loop and press the ‘Return’ button to return to the Analog Input screen. Enter the
desired minimum and maximum values for the loop set point that the input is to represent. The input range is -
32760 to 32760 for a decimal point resolution of zero, -3276.0 to 3276.0 for a decimal point of one, -327.60 to
327.60 for a decimal point of two and -32.760 to 32.760 for a decimal point resolution of three.
The function selection buttons,
None and SP , enable and disable the analog input. This allows the analog input
configuration to be maintained, but disable its operation until it is required. Select ‘None’ to prevent the analog
input from taking set point control over the selected loop. Press the ‘SP’ button to enable the analog input set
point control override.
Once all settings have been made, press the ‘Save’ button to save the changes. If you do not press the ‘Save’
button, all changes will be lost if you leave the screen or navigate to another analog input.
