Proportional bandwidth.
T
emperature
control
takes
place
by
changing
the
ON
time
of the
output:
the closer the
temperature
to the
setpoint,
the less
time
of
activation.
A
small
proportional
band
increases
the promptness of
response of the
system
to
temperature
variations,
but
tends to
make
it
less
stable.
A
purely
proportional
control
stabilises
the
temperature
within
the
proportional
band
but
does not cancel
the deviation from setpoint.
With
1PB
=0 the output is always o
ff.
1IT
0...999s
Integral action time.
The
steady-state
error
is
cancelled
by
inserting
an
integral
action.
The
integral
action
time,
determines
the speed
with
which
the
steady-state
temperature
is
achieved,
but
a
high
speed
(
1IT
low)
may
be
the
cause
of
overshoot
and
instability
in
the response.
With
1IT
=0 the integral control is disabled.
1DT
0...999s
Derivative action time.
Response
overshoot
may
be
reduced
by
inserting
a
derivative
Action.
A
high
derivative
action
(
1DT
high)
makes
the
system
very
sensitive
to small
temperature
variation
s and
causes
instability
.
With
1DT
=0 the derivative control is disabled.
1AR
0...100%
Reset of integral action time referred to
1PB
Decreasing
the parameter 1AR
reduces
the
integral
control
action
zone,
and
consequently
the
overshoot (see figure on paragraph
1IT
).
1CT
1...255s
Cycle time.
It’s the
period
in
which
the
output
ON
time
changes. The
quicker
the
system
to
be
controlled
reacts to
temperature
variations,
the smaller the
cycle
time
must
be,
in
order to
obtain
higher
temperature stability and less sensitivity to load variations.

CONTROLLER AUTOTUNING IN PID MODE
Before starting
In the
setup
mode
(see
configuration
parameters):
set 1CM=PID;
make
sure
that 1CH matches the
desired
operation
mode
(
1CH
=REF for refrigerating control,
1CH
=HEA for heating control); then adjust setpoint
1SP
at the desired value.
Start autotuning
During
normal

keep
buttons

define
the
dynamic

be
controlled. To
abort
the
autotuning
function,
press
; to start
autotuning
press
+
or wait for 30 seconds.
During autotuning
During
the
entire
autotuning
phase,
the
display
alternates
TUN
with
the
actual
temperature
measured.
In case of
power
failure,
when
power
is
resumed,
after the
initial
autotest
phase,
the controller
resumes
the
autotuning
function.
To
abort
the
autotuning,
without
modifying
the
previous
control
parameters,
keep
button
pressed for
3
seconds.
After
the
autotuning
has
taken
place
successfully, the controller updates the control parameters and start to control.
Errors
If the autotuning function failed, the display shows an error code:
E1

the controller
could
not
bring

RECALIBRATION
Have a precision reference thermometer or a calibrator to hand. Ensure that
■
OS1

■
During the auto-test phase, press buttons
■

and keep them pressed till the controller shows
0AD.
With
buttons
■
and
select 0AD or SAD
:
0AD
allows
a
calibration
of
0,
inserting
a constant
correction
over
the
whole
scale
of
measurement.
SAD
allows
a
calibration
of the top part of the
measurement
scale
with
a
proportional
correction
between
the
calibration point and 0.
Press
■
to
display
the
value
and then
use

or
to
make
the read
value
coincide
with
the
value
measured
by
the
reference instrument.
Exit from calibration by pressing button
■
.
OPERATION
The
L03B--
controller
,
size
71x98x61
mm
(WxHxD),
is
to
be
secured
to a DIN
rail
in
such
a
position
as to
ensure
that no
liquid
■
infiltrates causing serious damage and compromising safety
;
Make
sure
that
electrical
connections
comply
with
the paragraph
“wiring
diagrams”.
To
reduce
the effects of
electromagnetic
■
disturbance, keep the sensor and signal cables well separate from the power wires.
Place the probe
