4.1. Important Information
Observe the permissible intake and exhaust
pressures, since otherwise the motor may seize
and become damaged.
Mixing up the connections leads to a
dangerous overpressure overload.
Prevent internal condensation, transfer of
liquids or dust. The diaphragm and valves will
be damaged, if liquids are pumped in significant
amount!
When the pump is running, surfaces and motor
casing become hot.
If the pump is subjected to condensates it
should be allowed to run for a few minutes
under atmospheric pressure before switching
off.

4. Operations
4.4. Shutting Down The Pump
For a short time after accumulation of condensate:
➡
Allow the pump to continue running for a few minutes with
open intake connection.
➡
After having pumped aggressive media, clean pump heads
and remove deposits; check for damage if necessary.
Shutting down for longer periods
➡
Carry out measures as described for a short time stop.
➡
Disconnect intake and connection line from the vacuum
equipment.
➡
Close intake and pressure connections.
➡
Store pump dry.
4.3. Select rotation speed control
Standalone operation
In the the standalone operation mode the pump can be opera-
ted in two different modes: High-speed mode and Low-speed
mode.
To select the operating mode, the DIP switch 2 on the control
board in the terminal box must be set.
➡
Select the desired DIP switch setting on the PCB.
➡
Connect power supply via connection cable (PM 051 421 -T)
with T
TP PS S 110000.

Operating modes for stand-alone operation
Operation in Turbo mode
If the MVP 006-4 is to be operated with a TPD 011 or TMH 071,
Turbo mode must be selected.
➡
Connect power supply via connection cable (PM 061 192 -T)
with TPS 150.
➡
Select the DIP switch setting "OFF".
➡
When the rotation speed of the turbo pump which is being
used reaches the pre-set switch-point of 80 % of the maxi-
mum rotation speed (f
max
), then the rotation speed of the
MVP 006-4 is lowered.
– The preset trigger point can be varied in the range from
50 ... 97 % using parameter 701 in the TC 100 (see also
operating manual "PM 0547 BN Pump operation with
DCU").
4.2. Switching On The Pump
➡
Switch the pump on and off using the TPS.
The pump can be switched on and off at all
times.
