moviBOOST VP
The unit must not be put in operation without
having been filled with water first; this also
applies to test runs, even for checking the direction of
rotation.
Unions between the pump and the pipeline must always be
retightened. Flanged connections must also be checked
for tight fit.
Set the master switch to ‘‘0’’; unlock all motor protection
switches (if applicable). Provide connection to power supply.
Ensure that the motor’s cooling-air inlet and outlet openings
remain unobstructed.
Open / loosen the vent plugs on the pumps (for vent plugs
refer to the annexed pump operating instructions).
Slowly open the inlet-side shut-off element and prime the unit
until the fluid escapes through all vent holes. Close and slightly
tighten the pump vent plugs.
Switch on the master switch and start up one pump after the
other via the corresponding motor protection switch, making
sure that the motor runs in the correct direction of rotation as
indicated by the arrow on the motor.
Prior to starting up individual pumps, open the discharge-side
shut-off element.
When the pumps are running, loosen the vent plugs again to
let any remaining air escape. Then retighten the vent plugs
carefully.
Check the pump for smooth running and close the discharge-
side shut-off element for a short period in order to verify whether
the pump reaches the shut-off head.
Having checked each pump as described above, all motor
protection switches may be actuated and the unit set to
automatic mode.
On units with manual-0-automatic switch (supplementary
equipment) set all pumps to automatic mode.
Minor leakage of the mechanical seals during start-up is
normal and will cease after a short period of operation.
If the master switch was turned off at any time
during the above procedure, the unit will not
begin operation until after the pre-set delay period.
7.3 Checking the direction of rotation
For test operation each pump must be started up individually
to check the direction of rotation. If a pump is found to be
running in the wrong direction, switch two phases on the motor
terminal board.
7.4 Functional description / Automatic mode
After start-up, pressure boosting units in standard design will
run in automatic mode. For units with manual-0-automatic
switch, set all pumps to automatic mode.
Each pressure boosting unit has been factory-checked and
set to the required operating data.
The factory settings may only be altered by
duly qualified staff.
The PBU comprises 2 to 6 pump units (including stand-by
pump). Cascade operation ensures that the pumps are
operated in accordance with the momentary water
consumption, i.e. the individual pumps run only in line with
the actual demand.
The stand-by pump ensures uninterrupted operation of the
unit, if one pump does not function properly or breaks down.
In the case of a pump failure, the next free pump is started up
at once and the fault is reported.
The start and stop signals for the pumps are transmitted by the
discharge-side pressure transmitter to the PBU’s control
element, analysed and transmitted as an output signal via the
contractors to the individual pumps.
7.5 Starting the unit
Switch on the master switch to supply the unit with power. The
green LED on the control panel indicates the unit’s readiness
for operation.
7.5.1 Function of the control panel
The control panel comprises a back-lit display, function and
navigation keys, LEDs and an access point for the service
interface.
The display shows important information for operating
moviBOOST. Data can be displayed in plain text and
parameters can be set.
