1.3 Scope of delivery

These installation and operating instructions apply to the

Grundfos Control MP 204. The Control MP 204 is a control

cabinet with built-in motor protection.

These instructions only focus on the Control MP 204 control

cabinet.

The main component in the control cabinet is an MP 204 motor

protector. This component is not described in detail in this

manual.

Further documentation supplied with the Control MP 204:

• Technical documentation:

– wiring diagram

– parts list

– sectional drawing, etc.

• Installation and operating instructions for the MP 204.

For information on MP 204, see the installation and operating

instruction for the product.

Fig. 1 Example, Control MP 204

2. Installing the product

Before installation, check the following:

• Checkthat the specifications of the Control MP 204 correspond

to the order

• Check the product for transport damage.

Contact the transporter immediately in case of damage.

The Control MP 204 is operated either manually or via remote

access (optional). See section 3.2 Operation.

2.1 Mechanical installation

This section describes the mechanical installation of the Control

MP 204 and also provides general advice about how to position

sensors in order to achieve stable, measured values.

The control cabinet is designed for indoor use, either mounted on

a wall or directly on the floor.

2.1.1 Sensors

To ensure correct and reliable operation of the Control MP 204, it

is important to position and install sensors according to the

manufacturer's instructions.

2.1.2 Configuration of the product

Use Grundfos GO Remote to configure Control MP 204. See

4.2 Grundfos GO Remote.

2.2 Electrical installation

The electrical connection must be carried out by an authorised

electrician in accordance with local regulations.

The electrical installation must be carried out according to the

wiring diagram supplied with the Control MP 204.

Fig. 2 Example, Control MP 204, DOL version

The following sections are intended as a supplement to the wiring

diagram supplied with the Control MP 204.

The terminal blocks, X1, X10, X11, are shown in section

2.2.1 Terminal blocks.

TM07 1342 1318

If the product is to be used outdoors, it must be

located in a separate cabinet which is suitable for

outdoor use.

The sensors must always be correctly sized for the

range they are to measure. If the sensors are too

small, they will be saturated. If they are too big, the

resolution of the sensor signal will be too poor.

WARNING

Electric shock

Death or serious personal injury

Before starting any work on the product, make sure

that the power supply has been switched off and that

it cannot be accidentally switched on.

3. Commissioning the product

Checks before first startup:

• The pump is installed according to the installation and

operating instructions for the pump type used.

• The MP 204 is configured either by use of a PC Tool or with

Grundfos GO Remote according to the motor and pump

specifications.

3.1 Startup

The motor current and trip conditions have to be adjusted and set

during startup. To adjust and set these parameters, see

installation and operating instructions for the MP 204.

Check that the motor and pump operates according to the

specifications.

3.2 Operation

Control MP 204 is operated via a "H-O-A" switch in the cabinet

front or via a PC.

Manual, H

In Manual mode, the pump starts directly in DOL or SD mode.

Off, O

In Off mode, the pump is switched off.

Auto, A

In Auto mode, a pressure switch, float switch or a signal from a

PLC system, is used to control the pump.

For manual operation, both variants of the Control MP 204

incorporate the following components in the cabinet front.

Fig. 8 Example, Control MP 204

The Control MP 204 operates with two sets of limits:

• a set of warning limits

• a set of alarm limits, trip.

If one or more of the warning limits are exceeded, the motor

continues to run.

If one of the alarm limits is exceeded, the motor is stopped.

4. Product introduction

The Control MP 204 is used to start and stop the pump according

to an input signal. The input signal comes either from a main

control system, like a PLC, or from a simple input, like a switch.

The built-in MP 204 motor protector will ensure long service life of

the pump.

The Control MP 204 can optionally be fitted with a Grundfos CIU

unit, Communication Interface Unit, enabling transmission of the

collected data.

4.1 Modules

The Control MP 204 is designed to protect the motor both

electrically and mechanically.

MP 204 motor protector

The MP 204 protects the motor electrically by disconnecting the

motor or pump when one of the trip limits has been reached.

Trip conditions:

• Overload

• Underload, dry running

• Temperature, Tempcon sensor, PTC/thermal switch and Pt

sensor

• Missing phase

• Phase sequence

• Overvoltage

• Undervoltage

• Power factor, cos φ

• Current unbalance.

Sensor inputs and output:

• Pt100 or Pt1000 sensor

• PTC sensor.

See installation and operating instructions for the MP 204.

4.2 Grundfos GO Remote

The product is designed for infrared communication with

Grundfos GO Remote. MP 204 must be configured using

Grundfos GO Remote.

Grundfos GO Remote enables setting of functions and gives

access to status overviews, technical product information, alarm

logs and actual operating parameters.

Fig. 9 Grundfos GO Remote communication via infrared

connection, IR

4.2.1 Infrared communication

When communicating via infrared light, Grundfos GO Remote

must be pointed at the control panel.

4.3 Communication

If a Grundfos CIU unit, Communication Interface Unit, is to be

used, we recommend you to fit it according to the wiring diagram

and layout supplied with the Control MP 204.

All variants can be extended with external communication as an

option.

5. Control functions

This section describes the available control modes:

• Switch control

– Control MP 204 controlled by a pressure switch

– Control MP 204 controlled by a float switch

– Control MP 204 controlled by a main control system, for

example a PLC.

5.1 Switch control

Control MP 204 controlled by a pressure switch

If a constant pressure is required in a closed system, a pressure

switch can be connected. The pressure switch starts and stops

the pump according to the setpoint, pressure. Use terminals X10:

3 + 4.

Fig. 11 Example, pressure switch

Control MP 204 controlled by a float switch

If a constant level is required in an open system, a level

sensor,float switch, can be used to start and stop the pump.

When pumping into an open tank or reservoir, the pump is started

when the water level reaches the start level. The pump is stopped

when the stop level is reached.

The digital sensors used must be potential-free switches, like a

float switch or a similar type of switch. Use terminals X10: 3 + 4.

Fig. 12 Example, float switch

Control MP 204 controlled by a main control system

The Control MP 204 is controlled by a main control system, pos.

1, fig. 13, for example a PLC or a similar main control system.

Fig. 13 Example, main control system

6. Taking the product out of operation

6.1 Decommissioning

Observe the following if the product is to be permanently taken

out of operation.

An electrode relay can optionally be installed as

dry-running protection.
