1 Safety instructions

Appropriate use

The MVD2510 with the connected transducers may be used for measurement
and directly related control and regulation tasks, only. Any other use is not
appropriate. To ensure safe operation, the transducer may only be used
according to the specifications given in this manual. It is also essential to
comply with the legal and safety requirements for the application concerned
during use. The same applies to the use of accessories.

Each time, before starting up the equipment, you must first run a project
planning and risk analysis that takes into account all the safety aspects of
automation technology. This particularly concerns personal and machine
protection.

Additional safety precautions must be taken in plants where malfunctions
could cause major damage, loss of data or even personal injury. In the event
of a fault, these precautions establish safe operating conditions.

5

This can be done, for example, by mechanical interlocking, error signaling,
limit value switches, etc.

WARNING

Due to the fact that the device has not been equipped with a proper mains
switch, the supply cable must not be connected directly to the mains. VDE
guidelines require that the device can be disconnected from the mains via a
switching device (double-break disconnector). It is essential that the discon­nector is labeled accordingly and easy to access and operate by the user.

Before connecting the device, make sure that the mains voltage and current
type specified on the name plate correspond to the mains voltage and current
type at the site of installation and that the current circuit used is sufficiently
safe.

Devices designed for panel mounting may only be operated in an EMC-tested
control cabinet. (see page LEERER MERKER).

The device complies with the safety requirements of DIN EN 61010-part1
(VDE 0411-part1); protection class I.

Zero value (zEro)

A value for the measuring system’s zero balance is adjusted (unit mV/V).

Possible input: From "0.2 ... 3.8 mV/V.

Meas. range(rnGE)

A full-scale value (unit mV/V) can be adjusted. If the adjusted value is not
within the input range, the minimum or maximum permissible value will be ad­justed:

Possible input: From "0,2 ... 3,8 mV/V.

Tare value (tArA)

A tare value (related to full-scale) can be defined.

Level (PEGL)

The level is adjusted in display units (e.g. 2.000 kg).

Hysteresis (HYSt)

The hysteresis is entered to prevent a ”fluttering” of the limit-value switch
when the switching threshold is reached. The hysteresis results from the
differential between switch-on and switch-off threshold.

A value is set in display units, e.g. 0.200 kg.

7 Example

The below example uses a measurement task to show the device functions
and the required setups.

Measurement task: Filling a container

Containers are filled by weighing on a platform weighing machine. The plat­form is fitted with a load cell with a measurement range of 100 kg (corres­ponding to 2 mV/V). The weight of the platform itself is not known, but it is
less than 10 kg. The empty weight of the container is about 10 kg. The con­tainers are placed singly on the platform, tared and filled with 52 kg.

Balancing

Weighing machine adjustment with a partial weight of 50 kg
Platform weighing range (display full−scale value): 80 kg.

39

Number step: 1
Filter setting: 2 Hz

Limits

The container is filled with a net weight of 52 kg (Set value of Li1). If 2 kg
(Limit Li2) is undercut, a signal is produced that there is no container on the
weighing machine (referred to gross value).

The hysteresis for both limits is 0.5 kg.

Changes to the Li1 limit threshold should be able to be carried out by the op-

erator using the direct key
ons.

Other details

In order to prevent unauthorised changing of the parameters, the access to
the settings is only possible with a password (e.g. 1510).

The net signal should be available as an analogue signal (4...20 mA).
Changing of the zero point via the keyboard should not be possible.

. Limit 2 should not be changed for safety reas-

Taring is carried out via the external Control Contact 1 or with
second contact has no function. Remote control is not provided. The zero
point and tare values should be saved buffered against mains failure.
