Warning and safety informat i on 1.4

The meter PTM40/PLF40 has the protection class III.
It was manufactured and tested according to DIN EN 61 010, Part 1, „Protective Measures for electronic

measurement devices and control devices” and has left the factory in an impeccable condition as concerns
safety technology. In order to maintain this condition and to ensure safe operation, the user should observe the
notes and warning information contained in the present operating instructions. Development and production is
done within a system which meets the requirement s laid down in the DIN EN ISO 9001 standard.

For reasons of safety, the meter PTM40/PLF40 and the power supply (VER05US050-JA) must be opened
by authorised persons only; this means, for instance, that work on electrical equipment must only be performed
by qualified specialists. In the case of nonobservance of these provisions the titrator and the power
supply may constitute a danger: electrical accidents of persons or fire hazard! Moreover, in the case of
unauthorised intervention in the titrator or the power supply, as well as in the case of negligently or deliberately
caused damage, the warranty will become void.

Prior to switching the device on it has to be ensured that the operating voltage matches the mains voltage.
The operating voltage is indicated on the power supply. Nonobservance of this provision may result in
damage to the titrator and the power supply, or in personal injury or damage to property!

6 / 25

If it has to be assumed that safe operation is impossible, the meter has to be put out of operat ion
and secured against inadvertent putting to operation! Switch the meter off, pull plug of the mains cable out
of the power supply, and remove the meter from the place of work.

Examples for the assumption that a safe operatio n i s no longer possible,

• if the package is damaged,

• if the meter shows visible damages,

• if the power supply (VER05US050-JA) shows visible damages,

• if the meter does not function properly,

• if liquid has penetrated into the casing.

• if the meter has been altered technologically or if unauthori zed personnel tried or succeeded

to open the instrument as attempt to repair it.

In case that the user operates such a device, all thereof resulting risks are on the user.

The meter must not be stored or operated in humid rooms.

The relevant regulations regarding the handling of the substances used have to be observed:

The Decree on Hazardous Matters, the Chemicals Act, and the rules and information of the chemicals trade. It
has to be ensured on the side of the user that the persons entrusted with the use of the meter are experts in the
handling of substances used in the environment and in titrator or that they are supervised by specialised
persons, respectively.

Use only the sensors, sensor cables and interface cables recommended by the manufacturer. The notes
and statements in the respective user manuals and data sheets apply to the use of the sensors and fittings.

The device does not contain any components that need to be replaced and must only be opened for repair
by the manufacturer's technicians.

If in doubt, please contact the supplier.

2 Set up and Commissioning

Scope of delivery 2.1

The scope of delivery is shown on the included packing list.

There is a detailed list of the individual sets in  chapter „Scope of delivery”

Accessories can be found in  chapter „Accessories”

Unpacking and Setup 2.2

The meter and all accessories were carefully i nspected for function and size accuracy at the factory .
Please make sure that you also remove all of the small additional parts from the packaging.

The meter can be set up on any even surface.

The safety of the system, in which the device will b e integrated, is the responsibility of the installer.

If the meter is transported from a cold into a warm environment, there can be malfunctions in the device
caused by condensate. In this case, you have to wait until the device temperature and the room temperat ure
have reached a balance before you start the meter.

The flawless function and operational safety of the meter can only be warranted under those climat e

conditions specified in  chapter „Specifications”.

Power supply 2.3

The meter is delivered ready to operate with a 5 V DC power supply.

7 / 25

Position the power supply where it is easily accessi bl e so t hat the meter can be separated from the power
at any time.

Check the power supply regularly. If the power supply is damaged it must be promptly replaced by an
undamaged unit.

Use only the power supply VER05US050-JA (input 100-240 V~; 50/60 Hz; 0.18 A; output 5 V DC;
1 A max.; class II)!

3 Device description

Measuring inputs 3.1

Fig. 1 PTM40/PLF40

1) Sensor connection

2) USB port

3) Main Supply

On the front of the meter, there are special connectors to connect the sensor and a USB interface cable.

Use only the sensors, sensor cables and interfac e cables recommended by the manufacturer.
The notes and statements in the respective user m anuals and data sheets apply to the use of the sensors and
fittings. As the measuring system is intended for the measuring of analysis parameters you must keep in mind
that the sensors must be calibrated and maintai ned regularly.

The measuring input must be free of potentials and m ust not be connected to power conducting potentials.
All inputs must only be operated with the proper sens ors. T he direct connection of different signals is
prohibited!

In order to protect the connections from the ingression of moisture and the resulting corrosion,

you should always leave the sensor plugged into the m eter.

Please note the switches when connecting to other devices (e.g. via USB interface).
Internal connections in other devices (e.g. conn ect i ng GND to earth) can lead to impermissible v ol tage
potentials that can impair the function of the m eter itself or other devices or can even destroy them.

Use only interface cable (Interface HMG USB) to transfer data from the meter to the PC. This cable is not

included in the delivery and must be purchased separately ( chapter „Accessories”).
