4.5.1 Centesimal SET-POINT option (mod. M, V, X, Y) P3 - FHASE 2
In the MASTER configuration, the
RGF300
can be chosen with the
RGFPB1064 OPTION
.
This plug support the
SIMPLY
Set-point
(
P3
), with double digital commutators for
DUAL
Set-Point (
S3
switch) in
99
setting positions.
So it’s possible to set two (
2
) working Set-point (ex.: Night / Day – Winter / Summer, etc.) with
S3
switch
(led
SP1 / SP2
switch-on)
P3
CENTESIMAL
& DUAL
SET POINT
- mA (Vdc)
- °C
It is possible to activate the
SET-POINT
(the automatic regulation start point) by activating the
P3
centesimal switch (100 positions).
In the standard configuration, the Set-Point coincides with the maximum value of supply (100% or
value of P4 max. output).
The regulation scales are as follows in
'Master'
versions:
•
model
M
: from
4 mA to 20 mA
•
model
V
: from
0 Vdc to 10 Vdc
•
model
X
: from
10 °C to 60 °C
•
model
Y
: from
-20 °C to 20 °C
The direction of regulation goes from
'00'
(low values) to
'99'
(high values).
In
SLAVE
versions
(M
and
V)
, this trimmer
is not operative
(
STANDING
)
, even if present.
Note:
- for
M
versions, the regulation refers to the current control signal (
mA
)
- for
V
versions, the regulation refers to the voltage control signal (
Vdc
).
- for
X
and
Y
versions, the trimmer regulation refers directly to the temperature in
ºC
.
It is therefore necessary to change the "
range
" of the sensor being used to work out the
corresponding measured quantity / control signal.
