controls the venting automatically provided purge gas
is connected to the MAG and the MAG.DRIVE
digital
is programmed corre-
spondingly (“Vent on”).
■ Press the STOP key.
Deceleration

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 pur-
ged with dry nitrogen for one hour before switching off. During down times
of the system take care that neither ambient air nor cleaning agents enter
the pump.
3.9 Operating statuses
Switch-On Guard
The converter goes into the “Switch On Guard” operating status after the
power is switched on and after initialization. If there is no warning or failu-
re, it changes over into the “Ready” condition.
After a failure has been acknowledged, the converter goes into the “Switch
On Guard” operating status. The failure must be acknowledged a second
time, so that it then goes into the “Ready” condition.
Ready
The converter is ready and waits for the START command. All parameters
can be interrogated or changed via the operator control panel.
The basic menu parameters (refer to 3.10, Operating menu) can be scan-
ned via the operator control panel.
Acceleration
The pump continuously accelerates with the maximum current. The acce-
leration time is monitored to ensure that it lies within a programmed value
(refer to the menu “settings pump/Accel. Time”). If the converter hasn’t rea-
ched the normal operating mode during the monitoring time, then it is shut-
down with the failure message “Accel. Time”.
Normal operation
After a programmable frequency threshold has been reached (refer to the
menu “settings pump/Normal Operation”), the converter goes into the nor-
mal operation mode but the pump continues to accelerate up to the fre-
quency setpoint.
