Basic setup Standard

Venting

Short venting

 (e. g. in case of retardation of boiling or if sudden

foaming occurs):

➨

Press key VENT shortly (< 2 sec.).

☞

Pumping is interrupted, the process control is stopped.

Venting the system:

➨

Press key VENT continuously (> 2 sec.).

☞

Pumping is interrupted, the process control is stopped.

☞

Ventilation until pressure does not change any more, i. e.
until atmospheric pressure is attained

☞

Key STOP interrupts venting at any time.

The process control is inactive, i. e. controller is ready for vacuum
control, but control operation has not been activated.

☞

The controller is in operation mode two-point control, the
actual pressure is displayed.

☞

Values for set point p and hysteresis as from last operation
are reactivated.

☞

 Press key START/STOP to start process control.

☞

If using a cooling water valve, the valve must be configu-
rated, see section ”How to change the basic setup”.

After switching on

Starting and stopping the process control

In both modes (two-point control and continuous vacuum):

➨

To start

 the process control: Press key START/STOP.

☞

If the cooling water valve is preselected: Cooling water valve
opens immediately, the symbol is displayed.

☞

Isolation valve opens. If a cooling water valve is preselected,
at the first demand of vacuum the isolation valve opens 2
sec. past the cooling water valve: Pumped vapour reaches
cold surfaces of condenser.

➨

To stop

 the process control: Press key START/STOP.

☞

Attention:

 Take suitable precautions if the system risks to

become pressurized due to low boiling point solvents when
the isolation valve has been closed.

☞

If a cooling water valve is preselected: Cooling water con-
tinuous to run for additional 5 min. to allow condensation,
symbol cooling water is flashing.

Switching between two point control and continuous pumping

➨

Press key MODE.

☞

Mode change is only possible if the process control is inac-
tive (after switching on or pressing key START/STOP).

☞

The two-point control display disappears or appears.

MODE

Attention: If pressurized
inert gas is used install an
overpressure relief valve.
Max. pressure at the
pressure transducer 1600
mbar! Ensure that high
pressure is compatible
with the mechanical
stability of the system!
