Initialization Model 2090 Multi-Device Controller
EDITING PARAMETERS
The Model 2090 provides a versatile user interface for
editing configuration parameters, limits, and the current
position, by allowing several keys to perform multiple
duties. Prior to editing any settings, all device motion
should be stopped. The Model 2090 will automatically
stop device motion when configuration parameters are
displayed, and prevent the editing of limit and position
values while in motion, but the user should avoid
attempting to modify these values while equiptment is in
motion to avoid unexpected results.
To edit the limits or current position settings, select the
appropriate limit or position by pressing the corresponding
button under the LIMIT key group. The associated
indicator should light and the display will show the
corresponding value. For a tower, the 2090 provides two
sets of limits, one for horizontal polarization and one for
vertical, in order to protect antenna elements from damage
due to accidental polarization at the top or bottom of the
mast. Pressing the POLARIZATION key while the upper
or lower limit is displayed will switch the display to show
the corresponding limit for the opposite polarization,
without changing the tower polarization. To indicate
that the displayed value and polarization is not the current
polarization, the indicator light by the POLARIZATION
key will flash on and off. While in this state, the limit can
be changed using the limit edit keys just the same as any
other parameter.
