General information about BMS hs and BMS hp

The work site must be clean, free of salt or brine water and iron
filings. Clean the workplace with flushing water, if it is necessary.

1. If the pump is to be repaired at a service workshop, do the

following:

2. Check that the pump has not been damaged during

transportation.

3. Identify the type designation. See the pump nameplate.

4. If the repair is to be done on site before dismantling the pump,

check the installation:
– wiring connections (power supply and signals)
– hydraulic connections
– inlet and outlet pressure and flowmeter value(s), if possible
– protection: pressure switches, flow switches and motor

protection etc.

5. Compare the motor voltage and frequency details on the
motor and frequency converter nameplates with the power
supply available.

– Read and note down the trip and failure log of the frequency

converter.

5.1 Dismantling pump and motor

1. Remove the Victaulic clamp at the inlet-and outlet.

2. Remove the service connector, if it is installed.

4. Loosen the clamps and pull the pump towards the outlet port if

5.8.1 Before aligning pump and motor

Before aligning the pump and motor, make sure that the drain
holes are pointing downwards. At the same time, the inlet pipe
must point upwards (position 12 o'clock).

This has to be done to ensure correct operation of the pump as
well as easy service and maintenance. You can change the
position of the inlet pipe at a later time. Carefully follow the
instructions in section 5.8.2 Aligning motor and pump.

www.motralec.com / [e-mail] / 01.39.97.65.10

In this section you find information about how to set parameters
via PC.

6.1 Grundfos BMS hs

Find the newest setting software at the Leroy-Somer website:
http://www.emersonindustrial.com.

6.1.1 POWERDRIVE FX, MD and MD2

With MDX-SOFT, setting parameters and supervising the
POWERDRIVE from a PC is very user-friendly.
Numerous functions are available:

• quick commissioning with the simplified menu

• file saving

• help file

• comparison of two files or one file with the factory settings

• supervision in table or progress bar form

• diagnostics

• representation of parameters in a table.
You can download the MDX-SOFT software from the Internet at

the following address: http://www.leroy-somer.com/fr/
telechargements/logiciels/

To connect the PC to the POWERDRIVE, use an
"MDXUSBIsolator" isolated USB kit.

Procedure:

1. Connect the PC (USB-A) to the POWERDRIVE controller
(USB-B) via the USB connection. The communication is ready
when you can read the "USB" on the display of the red
indicator light

3. Select an action
– "Supervision only"
– "Download drive settings"
– "Create new file"
– "Open existing file"
– "Data logger".

4. Select the needed action menu
– "Simplified menu"
– "Advanced menu"
– "General setup"
– "Supervision menu"
– "Monitoring"
– "Charts".

1. Supply voltage

2. Current consumption

Do not perform a standard insulation test (high
voltage test).

Measure the voltage between the phases with
a voltmeter.
Connect the voltmeter to the terminals of the
frequency converter.

TM00 1371 3597

Measure the current of each phase while the
pump is operating at a constant discharge
pressure, if possible at the capacity where the
motor is most heavily loaded.
For information on the normal operating
current, see the "Technical specifications".

TM00 1372 3597

When the motor is loaded, the voltage must be within ±
5 % of the rated voltage. If the voltage varies more
than that, the motor may burn.
If the voltage is constantly too high or too low, replace
the motor by a motor that corresponds to the supply
voltage.
Large variations in the supply voltage indicate poor
power supply, stop the pump until the defect has been
found.
It may be necessary to reset the frequency converter.

The difference between the current of the phase with
the highest amp consumption and the one with the
lowest current consumption must not exceed 10 % of
the lowest current consumption.
If the difference exceeds 10 % of the lowest current
consumption, or if the current exceeds the full-load
current, check these possible faults:

• A damaged pump is causing the motor to be
overloaded. Pull the pump out of the sleeve for
overhaul.

• The motor windings are short-circuited or partly
disjointed.

• Too high or too low supply voltage.

• Poor connection in leads. Weak cables.
