1. General information

1.1 Hazard statements

The symbols and hazard statements below may appear in Grundfos

installation and operating instructions, safety instructions and service

instructions.

The hazard statements are structured in the following way:

DANGER

Indicates a hazardous situation which, if not avoided, will result in

death or serious personal injury.

WARNING

Indicates a hazardous situation which, if not avoided, could result

in death or serious personal injury.

CAUTION

Indicates a hazardous situation which, if not avoided, could result

in minor or moderate personal injury.

SIGNAL WORD

Description of hazard

Consequence of ignoring the warning.

- Action to avoid the hazard.

English (GB)

1.2 Notes

The symbols and notes below may appear in Grundfos installation and

operating instructions, safety instructions and service instructions.

2. Receiving the product

On receipt of the product, do the following:

1. Check that the product is as ordered.

If the product is not as ordered, contact the supplier.

2. Check that no visible parts have been damaged.

If any visible parts have been damaged, contact the transport company.

Observe these instructions for explosion-proof products.

A blue or grey circle with a white graphical symbol indicates that

an action must be taken.

A red or grey circle with a diagonal bar, possibly with a black

graphical symbol, indicates that an action must not be taken or

must be stopped.

If these instructions are not observed, it may result in malfunction

or damage to the equipment.

Tips and advice that make the work easier.

The membrane at the process connection of the level transmitter

must not come into contact with sharp or hard objects or be

damaged since it may result in incorrect measurements or even

media leakage.

English (GB)

3. Installing the product

DANGER

Explosive environment

Death or serious personal injury

- The products in these installation instructions are not intended

for use in potentially explosive areas.

CAUTION

Electric shock

Minor or moderate personal injury

- Install the product in a currentless condition.

The level transmitter must be grounded. To prevent electrolysis,

the shielding of the level transmitter must be set to the same

potential as the products usually found in the medium, such as

pumps and agitators.

The special cable for the level transmitter must be fitted so that the

pressure compensation in the cable assembly is not crushed. The

cable end must terminate in a dry room or in a suitable terminal

case so that no moisture can get through. In addition, the cable

must not be routed through damp conditions.

For variations in media, a guide tube must be used to prevent

measuring errors in flow caused by sideways movement and by

hitting the level transmitter against the walls of the container.

We recommend using a terminal case with a pressure

compensation element. See section 5.4.2 Terminal case with

pressure compensation element. The terminal case must be

mounted as close as possible to the surface of the medium while

still outside the medium.

The membrane at the process connection of the level transmitter

must not be damaged, otherwise it may result in incorrect

measurements or even media leakage. The membrane must not

come into contact with sharp or hard objects.

Level transmitters in free-field applications without integrated

overvoltage protection must be protected against electrical

discharge. In addition, we recommend using external overvoltage

protection upstream and downstream of the display or processing

unit.

4. Storing the product

The products must be stored in dry, clean conditions and protected against

external and mechanical damage.

The storage temperatures can be found in the technical data. See section

8. Technical data.

5. Product introduction

5.1 Intended use

Level transmitters are used to carry out hydrostatic level measurements in

ventilated tanks or to gauge water levels in open waters. They are designed

to hang vertically from the cable.

The correct level transmitter should be selected with regard to the measuring

range, version and specific measuring conditions on site before mounting,

installation and startup. The specifications provided by the manufacturer are

intended as suggestions only, except those relating to the test series. The

decision is to be made by the operator.

The manufacturer cannot accept liability for damage resulting from improper

use or in the event of use contrary to the intended purpose.

To prevent damage to the level transmitter and to safeguard its process,

mounting, installation and startup must only be performed by qualified

personnel. Personnel must be familiar with local regulations and be aware of

applied standards and directives to prevent bodily injuries and material

damage.

5.2 Pumped liquid

The PE-LD cable is shielded and suitable for use in water such as lake,

water well, and mine water. The cable is UV-resistant.

The FEP cable is shielded and suitable for use in water such as sea, lake,

water well, and mine water as well in different oils, fuels, and solvents. The

cable is UV-resistant.

The EPR cable is a submersible motor cable.

5.4 Accessories

5.4.1 Cable clamp

The cable clamp, part no. 99488578, holds the level transmitter in the liquid

at a defined depth and provides strain relief. Use of the cable clamp ensures

that the cable is not deformed.

The cable clamp is compatible with level transmitters with a cable diameter

of 5.5 to 10.5 mm. The maximum tensile strength is 2.5 kN. The case is

made of hot-dip galvanised steel sheets. The clamping jaws and guide clips

are made of fiberglass-reinforced polyamide.

Fig. 4 Cable clamp

5.4.2 Terminal case with pressure compensation element

The terminal case, part no. 99488577, is used for secure installation of the

level transmitter cable. The end of the pressure equalisation hose is always

protected from deposits and condensation (IP65). The remaining distribution

can be performed with a standard cable without a pressure equalisation

hose.

The terminal case must be mounted as close as possible to the medium

surface while still outside the medium to ensure the system is implemented

cost-effectively and in the best possible way.
