Operation
ATTENTION!
Danger of damage to the vacuum pump.
Frequent starting/stopping by switching the power supply on/off.
Starting the vacuum pump by switching the power supply on/off is permitted at most once
per minute (max. 60 x hour). At least 10 seconds must pass between switching off and on
again. If the process requires more frequent starting/stopping of the vacuum pump, this must
be done via the digital start signal.
The number of starts per hour through a digital signal is not limited.
CAUTION
Burn hazard!
The surface of the vacuum pump may reach operating temperatures in excess of 70 °C in
operation.
Do not touch the vacuum pump during and directly after operation.
CAUTION
Danger of hearing damage.
Noise development of the running vacuum pump.
Use hearing protection near the vacuum pump.
•
Ensure that the installation conditions (chap. 6.1) are fulfilled.
•
The permitted maximum number of starts (60) per hour must not be exceeded.
•
After a few minutes of vacuum operation, check the oil level and top up oil if necessary.
Starting the Vacuum System
•
Set the main switch (100Q1, fig.
9) to “ON”.
•
The vacuum pump starts immediately and switches on and off depending on the pressure.
The vacuum system is in operation.
Stopping the vacuum system
•
Set the main switch (100Q1, fig.
9) to “OFF”.
•
The motor switches off.

Pressure control
With pressure control, the vacuum pump will adjust the revolutions of the vacuum pump de-
pending on the deviation of the actual value from the target pressure.
If the actual value is above the target pressure, the vacuum pump revolutions are increased. If
the actual value drops below the target pressure, the vacuum pump revolutions are reduced.
At extended operation at the minimum speed, the vacuum pump will drop into stand-by
mode, which means that the vacuum pump will switch off and start again independently once
the actual value is by 1% above the target pressure.
