Wiring Description
Input En A change in the status from 0 to 1 at
input En (Enable) applies the start/
stop level (Offset ”B” + StSp) to the
output for 100 ms and starts the ramp
operation to the selected level.

A change in the status from 1 to 0
immediately sets the current level to
Offset ”B”, which makes output AQ
equal to 0.
Input Sel SeI = 0: Level 1 is selected
SeI = 1: Level 2 is selected
A change in status of Sel causes the
current level to start changing to the
selected level at the specified rate.
Input St A change in the status from 0 to 1 at
input St (Decelerated Stop) causes
the current level to decrease at a
constant rate until the start/stop level
(Offset ”B” + StSp) is reached. The
start/stop level is maintained for
100ms and then the current level is
set to Offset ”B”, which makes output
AQ equal to 0.
