4.0 CONTROL TRIMMER
WARNING
: Before starting the regulator calibration phase, check the position of the
trimmers as shown in figs. 26 and 27.
The position of the trimmers marked with a spot of red paint (factory calibrated trimmers) must not be altered.

The work parameters regulation can be divided into
TWO PHASES:
1.
definition of regulator work limits
: the values of
P4
and
P5/P6
are defined in this phase.
2.
definition of regulator work field
: the values of
P2
and
P3
are defined in this phase.
With
SLAVE
type regulators, the regulator calibration is completed during
PHASE 1
.
With
MASTER
type regulators,
PHASE 1
is necessarily followed by
PHASE 2
which defines the
Work
Range
and
Set-point
.
N.B.:
it is possible to read the work parameters by connecting the
HELP1
portable display unit; press the
keys as shown in
fig. 28
to display the readout of the value set with the calibration trimmers.
