2-4 Control Modes
MANUAL mode (fixed value control)
The vacuum is controlled by the fixed pressure (Set
Press) after starting operation.
The setting range of the fixed pressure (Set Press) is
VAC (continuous depressurization) to 1013 hPa (760
mmHg).
The fixed pressure value can be changed regardless of
whether the equipment is in standby, depressurization
or fixed value control.
Automatic stop according to the operating time can be
performed by setting operation stop conditions (Auto
Stop).
There are four types of functions in the vacuum
control mode.

AUTO mode (automatic control)
You can select from two types of automatic control modes:
AUTO mode and AUTO-2 mode.
AUTO mode automatically controls the pressure in order to
prevent bumping and automatically determines the pressure
(Mark Press) at which both recovery rate and concentration
time can be compatibly performed.
Automatic stop according to the operating time can be
performed by setting operation stop conditions (Auto Stop).
AUTO-2 mode requires optional vapor temperature sensor.
In addition to the functions of AUTO mode, the following
functions can be performed:
•Fixed pressure control at automatically determined
pressure (Mark Press) according to the vapor
temperature (Set Temp)
•Automatic stop due to temperature rise (Stop Temp)
over the vapor temperature (Set Temp)
•Able to accept mixed solvents by adjusting temperature
(Adjust Temp) and the number of adjusting time (Mark
Count).
•This mode is preset so that the optimal state is attained
when; the room temperature is 25 °C ±3 °C and the
cooling water temperature is 5 to 10 °C,
Low boiling point solvent, bath temperature 40 °C
High boiling point solvent, bath temperature 60 °C
•Bumping may be inevitable for some samples. In such a
case, try to reduce the volume of samples, reduce the
rotation speed of the sample flask or lower the bath
temperature. Time

STEP PROGRAM mode
PROGRAM mode (slope control)
In this mode, appropriate vacuum control according to the
solvent can be performed using a total of 65 solvents in the
database. The database is contained with the 10 solvents that
user can set arbitrarily and typical 55 solvents including pre-
programmed 10 solvents with appropriate settings.
The factory default solvents are as follows:
* The factory default settings are appropriate:
when the bath temperature is 40 °C, the cooling water
temperature is 5 to 10 °C and the room temperature is
25 °C ±3 °C.
Slope control by the slope time (Slope Time) is performed from
the slope starting pressure (Slope Point) to the fixed pressure
(Set Press) and then the vacuum pressure is controlled by the
fixed pressure.
Automatic stop by the operating time can be performed by
setting operation stop conditions (Auto Stop).
Up to 18 characters can be used for the user-registered
solvent name.
You can use alphanumeric characters, spaces and symbols
( ,. -+*/()).
There are 5 programs with up to 99 steps to be used
as a programmable vacuum controller. Fixed value
control, slope control and atmospheric vacuum release
can be programmed.
The vacuum pressure is controlled by the set pressure
(Press) and the step operation time (Time).
The following items can be set in the program
execution setting screen:
Start step number (Start Step No.)
Finish step number (Finish Step No.)
Number of repetitions (Repeat)
Automatic pressure relief (Auto Leak)

Safety features
Safety features (the settings can be changed in the temperature controller)
1. Temp Alarm (upper/lower temperature limiter)
If the measured bath temperature exceeds the set
upper or lower limit, the control will stop and the alarm
will appear on the screen.
You can set the temperature limits and also enable or
disable alarms.
* In the factory default setting, the alarm is enabled.
(High (upper limit) +220.0 °C / Low (lower limit): -
20.0 °C)
* In case you set the temperature close to the upper or
lower limit, you should consider the effect of overshooting,
undershooting and fluctuations of the temperature before
it’s being stable.

※The temperature setting of the stand-alone over-heat protector must be set at the maximum temperature
(250 °C) in normal use in order to detect the empty heating of the bath.
When using oil, if the stand-alone over-heat protector is not set at 250 °C, or if the temperature control
is performed without rotating the sample flask, the stand-alone over-heat protector may be activated due
to ununiformed of temperature.
The temperature setting can be adjusted within variable range if necessary.
