defined by the translucent green arc on the face of the Line speed input
meter.
Line speed input (gauge) – The analog line speed meter shows the live value
of the 0-20mA line speed input. The calibrated range is also shown by the
translucent green arc which appears on the meter face.
Minimum Limit – This control accepts entry of a value between 0% and 100%
to specify a minimum value for the line speed signal. The calibrated line
speed value is prevented from dropping below the specified limit regardless
of the actual line speed input. This is used to set a minimum correction
speed to be applied even when the line speed drops below the specified
percentage.
Calibrating the line speed input
Before using the line speed control feature, the line speed input should be
calibrated to match the line speed input signal. During calibration, the
minimum line speed signal is applied followed by the maximum line speed
signal. When speed gain control is enabled, these minimum and maximum
line speeds then correlate to minimum and maximum guide correction
speed.
Line speed calibration operates correctly regardless of line speed input
polarity. For example, a Minimum Speed producing 10mA with a
corresponding Maximum Speed producing 2mA is acceptable. In all cases,
the Minimum Speed must be presented first.
Start Calibration – Press this button to start the line speed input calibration
process. In order to complete calibration, the line speed input will need to be
presented at the minimum line speed followed by the maximum speed.
Set Minimum Speed – Press this button after applying the minimum line
speed signal.
Set Maximum Speed – Press this button after applying the maximum line
speed signal. A dialog box will appear after this step to confirm saving the
new calibration values. Press ‘Yes’ to confirm, or press ‘No’ to abort saving
the new calibration values. After new calibration values are saved, the
calibrated range indicator (translucent arc) on the line speed input meter is
updated to reflect the changes.
Enable speed gain control – Check this box to allow the line speed input to
control guide correction speed. A calibration of the line speed input is
recommended to ensure correct operation of this feature. Disabling this
