SETTING CURRENT POSITION ON 2090
The total travel between the mechanical limits is typically set
between 370 and 400 degrees at the factory. Set the 0 degree
position on the 2090 so that the 2090 moves the table between the
mechanical limits without engaging them in normal operation.
EXAMPLE (CW - clockwise, CCW - counterclockwise)
The table is rotated CCW until it stops at the mechanical limit. The
table current position is then set at 0. Then it is rotated CW till it
stops at the CW mechanical limit switch. The controller now reads
385 degrees which is the full travel between mechanical limits.
The current position on the 2090 is then reset to 360 about 10-15
degrees from the CW mechanical limit. This will keep it from
hitting both mechanical limits when rotating from 0 to 360 during
operation by the 2090.
CAUTION: ON RESETTING CURRENT
POSITION ON 2090
The 0 degree position of the 2090 controller is fixed with respect to
the mechanical limits described in the “Setting Current Position on
2090” section if they are not disabled per the instructions in the
“Setting Mechanical Limits” section.
Should it become necessary to reset the current position readout of
the Model 2090 Controller. The platform can be rotated
periodically back to a desired position and the 2090 current
position can be reset to 0 only if the mechanical limits are disabled.
The CW and CCW limits on the 2090 will continue to function
with the mechanical limits disabled. If the mechanical limits
remain in operation, the 360 travel on the 2090 will no longer be
between mechanical limits and normal operation will be
interrupted if they are not disabled per the instructions in the
“Setting Mechanical Limits” section.
