3.9.3 Single Loop Automatic Operation with Ratio and Bias

A set-point bumpless transfer is possible when AUTO RAT (ratio) or AUTO BIA (Bias) is

configured. These configurations calculate a ratio or bias value that balances the remote set-

point with the local set-point upon a switch from local to remote set-point.

Using Auto Bias, a switch from local to remote set-point will cause the bias value to

automatically adjust to the difference between the active set-point and the remote

set-point times the ratio value. For example, if the active set-point is 17.00 and the

remote set-point is 20.00 with a ratio of 2.00, then the auto bias value will be:

-23.00 = 17-(20*2).

Using Auto Ratio, a switch from local to remote set-point will cause the ratio value to

automatically adjust to the ratio between the active set-point minus bias and the

remote set-point. For example, if the active set-point is 17.00 and the remote set-

point is 20.00 with a bias of -23.00, then the auto ratio value will be:

2 = 17- (-23.00)/20.

From the Auto, Local, Bias display, press the R/L key to

switch from local to remote set-point (REM).

Bias value automatically adjusts to balance remote and

local set-points.

Press the ∆ or ∇ key to adjust the bias value and change

the active remote set-point by the bias value.

Press the scroll key until appears SP to view the new

set-point.

The same idea applies to use of ratio.
