8. CONTROLLER OPERATION

When the temperature controller is on, the PV display shows the value of measured
temperature, and the SV display shows the preset temperature value.
Basic settings:
Temperature setting: Press the SET button, the PV display shows „SP" the SV displays
shows the adjustable temperature value. When last digit blinks, set its value with the
and buttons. Use the button to switch to the next digit and set its value
using and .
After setting the temperature, press the SET button to set the timer.
Timer setting: Press the SET button, the PV display shows „SI" the SV displays shows
the adjustable timer value. When last digit blinks, set its value with the
buttons. Use the button to switch to the next digit and set its value using
After setting the time, press the SET button for the device to start operation with the
defined parameters.
Advanced settings:
CAUTION: All the controllers and parameters have been thoroughly tested and
set by the manufacturer. If the functional parameters of the vacuum dryer meet your
expectations and if the vacuum dryer runs properly, there is no need to modify these
parameters.
How to open the advanced settings:
Press and hold , then press SET. The display will show „LCK". Release the SET button
(while pressing ) and set the value of the blinking digit to „7". Release
SET. The display will show „ALH".
ALH – upper temperature limit alarm – set the desired value using
device will set off an alarm when the sum of the preset and upper limit temperature
exceeds the actual temperature value. Available values: range of 0 to 100°C.
After setting the upper temperature limit alarm value press SET in order to adjust the
lower temperature limit alarm – the display will show "ALL"

ALL – lower temperature limit alarm – set the desired value using
device will set off an alarm when the sum of the preset and upper limit temperature is
lower than the actual temperature value. Available values: range of 0 to 100°C.
After setting the lower temperature limit alarm value, press SET in order to adjust the
measured temperature value "SC".
SC – measured temperature value adjustment – the PV display shows the adjusted
temperature value. Available values: -50°C to +50°C.
After setting the measured temperature adjustment value, press SET in order to adjust
the PID controller self-regulation – the display shows "ATU".
ATU – enable or disable self-regulation of the PID controller – available values: „0"
– PID self-regulation disabled; „1" – PID self-regulation enabled. When this parameter
is set to „1", the device can be started in self-regulation mode. In order to start the
.
self-regulation mode, leave the advanced settings and, in the normal operation mode,
press and hold
and shows „ATU". During this process the actual temperature may differ from the
preset one – this is normal. The duration of the self-regulation function is about 3 to
5 minutes. After this time the PID controller will adjust its settings, in order to work
more precisely.
After setting, press SET in order to adjust the proportionality range "P".
P – proportionality range – heating control adjustment. Available values: from 0 to
400.0
After setting, press SET in order to adjust the integration time constant "P".
I – integration time constant. Available values: from 0 to 2000
After setting, press SET in order to adjust the differentiation time constant "d".
. The
d – differentiation time constant. Available values: from 0 to 1000
After setting, press SET in order to adjust the heating period "P".
T – heating time. Available values: from 1 to 60
After setting, press SET in order to adjust the thermal accuracy control range "HL".
HL – thermal accuracy control range. Available values: from 500 to 1.500
After setting, press and hold SET for about 5 seconds in order to leave the advanced
settings and save the changes.
