Samson TROVIS 6400 - Unit of Temperature Int; Digital Filter Inf; Select the Input Circuitry of the D (Derivative)-Action Component with DI; Select Setpoint SP

Unit of temperature
Int
Temperatures can be displayed in either °Celsius or °Fahrenheit.
0
—°C
1
—°F
Any change of this configuration block causes the new measuring range
limits to be stored.
Example:
In
=
0
→ Measuring range
In__
= –30.0 and
In
—
= 150.0 in °C
(with
Int
=
0
).
Change the unit of temperature to Fahrenheit with
Int
=
1
.
The new measuring range is now modified according to the limits below:
In__
= –22.0 and
In
—
= 302.0 in °F.
Digital filter
InF
Digital filter
InF
has the function of filtering analog input x. Range of values
0.0 to 120.0 sec., with 0.0 disabled; e.g., for fast controlled systems.
Select the input circuitry of the D (derivative)-action component with
dI
The differential-action component of the controller can be either directly ap-
plied to controlled variable x, or behind the setpoint/actual reference junc-
tion of xd (Fig. 1).
0
— To x-input
1
— To control deviation xd
Select setpoint
SP
Switching between setpoints W1 and W2 is accomplished either by actua-
ting the W1/W2 key (9), or applying an external signal (+24 V) via termi-
nal connections 2 and B of the binary input. Selection and combination op-
tions of the setpoints are determined via configuration block
SP
.
0
— W1 active, W2 disabled
1
— W1/W2 Switchover only permitted via key
2
— W1/W2 Switchover permitted by either key or binary input
(binary input has priority, i.e.,:
BE = 0 → Switchover permitted via key
BE = 1 → Switchover not permitted via key, W2 is active)
3
— Switchover permitted only via binary input
4
— Restart the setpoint ramp via binary input BE beginning from existing
x-value; W2 is disabled.
