Description Item
Off-low-high–three HPU control buttons (Off/Low/High) will appear
on the Station Manager Station Controls panel.
First On: True: Indicates that the first HSM turned on activates the
HPU. False: Setting First On and Last Off to False allows the HPU
to turn on independent of HSM power. Setting First On and Last Off
to True allows HSM Low selection to activate HPU high without
pressing the HPU buttons.
Last Off: True: Causes the last HSM turned off to turn off the HPU.
Visible: True: Indicates whether or not the HPU button is visible on
the control panel. Changing Visible to False turns off the HPU button
display on the Station Manager window, provided both First On and
Last Off are True.
