defined by the "dependence" parameter: the switching point is calculated by
adding a percentage "IN0" (from -100% to +100%) to the set-point of the
differential
(32) indicates the OFF switching point of the relay with respect to the point where the
ON switching took place. The OFF switching point is calculated by adding to the
ON point a percentage "DF0" (from -100% to +100%) of the differential.
Note: the default values of these parameters depend on the operating
mode and number of channels, as set out in the table below:
1 Channel

* The default values for mode 6 are the same as those of modes 0 or 1, depending
on whether the outputs are operating in direct or reverse.
