Voltage Range Selection; Current Limit Adjustment - Ametek L Series User Manual

L-Series and FCS-18- Graphical User Interface User Manual

6.5 Voltage Range selection

If the connected L-Series unit is equipped with dual voltage range
capability, the voltage range option box will be enabled and the selected
voltage range will be shown. This control can be used to
toggle between the two voltage ranges. The values shown for
each range are based on the hardware configuration settings.
Note : changing the voltage range will cause the output voltage for all
phases to be set to zero volts.

6.5.1 Current limit adjustment

The maximum amount of current available will be limited when switching
to the high voltage range. When the high range is selected, it may be
necessary to trim the current limit value back to avoid exceeding the
maximum available current in the high voltage range. This is done
automatically by the LSGUI program. Thus, the user may see his current limit
value change when he switches from low to high range. The opposite is not
true however. When switching from high range to low range, the set value of
the current limit is not changed but the maximum value is. The user will see
the position of the slider handle on the slider control change.
