2.6 E 5202 Converter adjustment
 The converter does not require specific calibration; it adapts
the position of the servomotor to the 0/4to20mA (or 0/
2to10V) input signal through combination with the potenti-
ometer's resistance value.
 The converter is fitted with a trimmer (Dead Band) posi-
tioned on the front panel; you are anyway recommended to
regulate the trimmer to the maximum value, (TRIM fully
rotated clockwise), to avoid a a reaction that is too frequent
with needless repositioning of the servomotor in the case of
very small variations of the input signal.
The maximum value of the Dead Band is 1%, that corre-
sponds to no repositioning reaction until the input variation
signal is more than 0.2 mA (or 0.1V) (angle of around 1°).

In the case of 115V electrical supply move the wire
from clamp 10 to clamp 11.
In the case of the 0/2 – 10V input signal move the
jumper onto clamp V.
