4.1 Operation with plug-in
control
Observe the general operation rules given
in Section 3.1
Switching on
• Switch on the MAG.DRIVE. The display reads
Ready
0.0 A 0 Hz
If the pump has the optional TMS (including e.g. the red
heater band) the heater will be activated. The setpoint
temperature will be reached within 30 - 60 minutes
depending on cooling water temperature and flow.
In case of corresponding connection the backing pump
will be activated when switching on the MAG.DRIVE.
• Open the purge gas supply.
• Open the cooling water supply.
• Press the START key.
The pump runs-up.
Acceleration
20.0 A 250 Hz
is diplayed until the frequency setpoint has been rea-
ched. Then
Normal Operation
1.0 A 480 Hz
is displayed.
The backing pump and the MAG can be switched on
simultaneously. In such a situation the MAG serves from
the very outset as an effective baffle.
Switching off
The MAG.DRIVE controls the venting automatically pro-
vided purge gas is connected to the MAG and the
MAG.DRIVE is programmed correspondingly („Vent
on“).
• Press the STOP key.
Deceleration
20.0 A 400 Hz
will be displayed. When the display reads
Ready
0.0 A 0 Hz
the pump has come to a standstill.
• Close the cooling water supply when the pump is
switched off in order to avoid condensate formation in
the pump.
The backing pump may be switched off once the MAG
has stopped.
If the MAG has been used for pumping corrosive gases
it should be purged with dry nitrogen for one hour befo-
re switching off. During down times of the system take
care that neither ambient air nor cleaning agents enter
the pump.
