3.2 Operation with the
START and STOP keys
Switching on
•
Switch on the MAG.DRIVE
digital
.
The MAIN LED lights green.
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. With a converter with
default settings the pump’s purge gas valve is open.
•
Open the cooling water supply.
•
Press the START key.
The pump runs-up. The STATUS LED is slowly flashing
green. When the STATUS LED is lit permanently green
the pump is in normal operation.
Switching off
•
Press the STOP key.
The STATUS LED is fast flashing green. When the STA-
TUS LED is off 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.
After a failure has occured and has been removed, ack-
nowledge the failure message by pressing the STOP
key.
Significance of the lamps
COM
(green)
Is lit if communication has been established via the
interface.
STATUS
(green/red)
Red, steady light
= Failure
Red, flashing
= Warning
Green, flashing (slow)
= Start delay, Acceleration
Green, flashing (fast)
= Deceleration,
Kinetic buffering
Green, steady light
= Normal operation
MAIN
(green)
This lamp is lit if the power is switched-on, and all of the
supply voltages for operation are available.
Flashes when the power fails as long as the power
supply voltages in the converter are maintained by the
kinetic buffering.
