4.5.5 INPUT MENU
Input
filter
Time constant, in seconds, of
the RC input filter on the PV
input. When this parameter is
Off the filter is bypassed.
Measure
Bias
This value is added to the mea-
sured PV input value. Its effect
is to shift the whole PV scale of
its value (±60 digits).
Sampling
Time
Sampling time, in seconds, of
the instrument. This parameter
is normally used when control-
ling slow process, increasing the
sampling time from 0.1... 10 s.

4.5.6 OUTPUT MENU
Control output
hysteresis
The parameter can be set
between zero and 5% of the
configured Span and set in
Engineering units.
e.g. Range = -200…600°C
Span = 800°C
Max. Hyst. = 5% 800° = 40°C
Control output
cycle time
Cool
cycle time
It’s the cycle time of the logic con-
trol output. The PID control out-
put is provided by the pulse width
modulation of the waveform.
Control Output
low limit
It specifies the minimum value of
the control output signal.
It is applied in manual mode, too.

Control output
high limit
Cool output
high limit
It specifies the maximum value
the control output can be set. It
is applied in manual mode, too.
Heat output
maximum rate
Cool output
maximum rate
This value, specified in %/sec-
onds, with range from 0.01 to
99.99%/s provides the maxi-
mum rate of change of the out-
put. When set to Off this func-
tion is disabled.
Soft start of the
control output
It specifies the value at which
the control output is set during
the start up phase.
#st.Op
#Op.rC
#Op.r
#Op.C.H
#Op. H
Soft start
time
This value specifies the time the
start up phase lasts. The start
up phase starts at power up of
the controller.
Travel
time
It provides the time required to
the motor positioner to go from
the 0% position to 100%
Minimum
step
It specifies the minimum allowed
time f activation of the output to
a motor positioner that produces
a sensible effect. It is related to
the deadband of the positioner
