1 Safety Information

1.1 General information

For your protection, please read and pay attention to all safety information prior to start-up of your

converter PAM2080.

Retain these instructions and all other information for future reference.

Utilisation other than that described here compromises the safety of persons and the entire measuring

equipment and is therefore impermissible.

The manufacturer will assume no liability for damage arising from improper or non-compliant utilisation

of the products.

DANGER!

Improper handling can lead to electric shock. “Hazardous voltages” representing a risk of electric shock

for humans may be present on non-insulated parts in the product’s casing. Therefore cut off the device’s

power supply prior to opening the connection cavity cover.

Assembly, electrical connection, start-up, operation and maintenance of the measuring equipment may

only be effected by trained personnel who must be authorised by the system operator for the activities

indicated. The trained personnel must have read and understood these operating instructions and must

follow the directions in these operating instructions.

Check that all connections are correct prior to starting up the measuring point as a whole. Make sure that

electrical cables and hose connections are not damaged.

Do not commission damaged products and protect these products from unintentional start-up. Label the

damaged product as defective.

If faults cannot be eliminated, you must remove the products from operation and protect them from

unintentional start-up. Repairs that are not described in these operating instructions must only be carried

out directly with the manufacturer or via the service department of KROHNE.

1.2 Display conventions

The following symbols are used to help you navigate this document more easily:

WARNING! DANGER!

These warning signs must be observed without fail. Even only partial disreagarding such warnings can result in serious health damage, damage to the device itself or to parts of the oprator´s plant.

CAUTION!

These warning signs must be observed without fail. Even only partial disreagarding such warnings can lead to improper functioning of the device.

NOTE!

This symbol designates important information for the handling of the device.

LEGAL NOTICE!

This symbol designates information on statutory directives and standards.

HANDLING!

This symbol designates all instructions for actions to be carried out by the operator in the specified sequence.

CONSEQUENCE!

This symbol designates all important consequences of the previous actions..

1.3 Installation

CAUTION!

First assemble the device at the definitive place of use. Using suitable screws, fix the device to a weatherprotected wall or weather cover, e.g. a pedestal.

Effect all electrical connections before switching on the device, otherwise damage is possible.

Water, moisture and dust

Converter PAM2080 is designed according to protection class IP 54 and correspondingly protected

against penetration of water, moisture and dust. Nevertheless, avoid extreme conditions.

Heat

Do not install converter PAM2080 close to heat sources, such as heaters, radiators, conduits containing

hot mediums. Avoid direct sunlight.

Power supply

Converter PAM2080 is equipped with a multi-range switching power supply and must only be operated

live within the indicated range (see Technical Data).

Mains connection

To ensure safe and impeccable operation converter PAM2080 must be securely connected to a mains

connection box by means of a mains cable.

Accessories

To ensure safe operation we recommend utilisation of our accessories.

www.krohne.com

1.4 Handling and Use

Cleaning

Where necessary, clean converter PAM2080 using a damp cloth and mild cleaning products. Use no

abrasive cleaning or scouring products (front film is sensitive to scratches). Never use solvents or

cleaning sprays containing solvents.

Decomissioning

Decommission the device if you notice damage to the casing, if you notice moisture in the device (e.g.

fogged display) or if the converter does not function as prescribed.

Transportation / return

It is recommended to transport the device in its original packaging across large distances or when

returning the device.

In the event of repair please send the device – cleaned – to the KROHNE sales office covering your area.

As far as possible, use the original packaging when doing so.

Please enclose the completed hazardous goods sheet (copy penultimate page of these operating

instructions) with the packaging and additionally with the dispatch documents.

Play your part in environmental protection

Converter PAM2080 also contains electronic parts that contain precious metals in small quantities. These

raw materials are fully recyclable. Please deposit electrical devices intended for disposal at appropriate

collection points (electrical scrap).

Unauthorised interventions in the device render the guarantee ineffective.

3 Installation

3.1 Mounting to wall or weather cover

Using appropriate screws, (d=6 mm), fix converter PAM2080 to straight surfaces (wall) or to a

weather cover (for example weather cover ZAB-04, order no. 5.520.004 with pre-drilled holes).

You gain access to the lower fixing eyes by opening the terminal connection cavity (all dimensions

indicated in mm).

3.2 Electrical connection

WARNING!

Electrical connection may only be carried out by authorised trained personnel.

Ensure that there is no voltage present in the mains cable before connection work commences.

Prior to connection, make sure that the mains voltage matches the voltage indicated on the type plate!

A clearly identified cut-off device must be installed close to the measuring system.

Fuse the measuring converter customer-side with 1.3 A.

Do not lay signal lines together with high-voltage lines in shared cable channels.

Switch on the measuring converter only with the sensors attached at all times.

4.2 Measuring channel display

4.3 Plug Connections (Probes)

As standard, two ports (F10) are included on converter PAM2080 for the direct connection of two

measuring probes, for example immersion probe AS75-S4 (see illustration on the right).

Connection to a PAM2080 converter

max. 2 probes directly to the converter

each additional probe via bus distribution boxes

(max. 8 probes on one PAM2080 converter = 8 channels)

Bus connection boxes and extensions for data cables are available as Accessories from KROHNE.

www.krohne.com

INFORMATION!

The converter recognises all connected probes automatically. You can attach and pin-align the probes at any port you choose, in any sequence you choose, even during operation. Data transmission between measuring probes and converter takes place via an internal bus system.

The system's plugs and ports are coded for reverse polarity protection.

Connect the corresponding data cable plugs with the ports on the immersion holder and converter

PAM2080 / bus distribution box.

Always secure the connections by tightening the plug retaining ring.
