Performance characteristics
METPOINT® BDL compact 7
4 Performance characteristics
Our longstanding practical experience in measuring and control technology was implemented in the new
METPOINT®BDL compact.
Stretching from the measuring data acquisition and automatic sensor identification via the visualisation
on the large color display, alarm signal, and storage, to the remote readout via web server – all of this
is possible with the METPOINT®BDL compact. An alarm message can be sent via SMS or e-mail in
connection with the BEKO METPOINT connect software.
With the 3.5" colour display with a touch panel, all of the information is visible at a glance. Operation is
very easy. All the measured values, measured curves, and exceeded limit values are displayed. With
a simple finger movement, the curve courses can be tracked from the start of the measurement.
The big difference to standard, paperless graphic display recorders is reflected in the simplicity of the
start-up and in the measuring data evaluation. All of the sensors are directly identified by the
METPOINT®BDL compact, and they are provided with voltage. Everything is ideally matched.
Multifunctional:
The METPOINT®BDL compact identi-
fies up to four sensors including all
BEKO sensors (consumption, dew point,
pressure, current, KTY, Pt100, Pt1000).
Any analog sensors (0/4 – 20 mA,
0 – 1/10/30 V), pulse) can easily and
quickly be configured.
Digital sensors can be connected via RS
485, Modbus RTU and SDI.
Flexible:
Network-compatible, and remote
data transmission worldwide via
Ethernet, integrated web server.
Alarm relay/trouble indications:
Up to 4 limit values can be freely
configured and assigned to 2 dif-
ferent alarm relays. Collective
alarms are possible.

10.1 Safety instructions
Danger!
Supply voltage!
The contact with non-insulated parts carrying supply voltage involves the risk of an electric shock
resulting in severe injuries and death.
Measures:
•Observe all regulations in effect during the electrical installation (e.g. VDE 0100)!
•Any electrical works must only be carried out by authorised and skilled personnel.
• The connection to the electric mains and the corresponding protective equipment must comply with
the legal provisions in force at the place of installation of the METPOINT®BDL compact; the con-
nection and installation must be carried out by skilled personnel who are qualified accordingly.
• Make sure that no parts of the measuring devices are energised and that the measuring devices
cannot be connected with the electric supply mains during service measures.
Danger!
Missing earth connection!
When the earth connection (protective earth) is missing, there is the risk in the event of
malfunction, that contactable, conductive components may carry supply voltage. Touching
of such parts leads to an electric shock with injuries and death.
It is imperative to connect the plant to earth or to connect the protective conductor accord-
ing to the regulations.
Do not use plug adapters at the power plug.
Have the power plug replaced by qualified skilled persons, if required.
Danger!
Missing separator!
All voltages representing a hazard when coming into contact with them must be disconnect-
able via assigned separators that need to be installed externally.
The separator must be installed in the vicinity of the device.
The separator needs to correspond to IEC 60947-1 and IEC 60947-3.
The separator must separate all voltage-carrying conductors.
The separator must not be installed in the power supply line.
The separator must be easily accessible for the user.

Installation
METPOINT® BDL compact 17
The plug of the power supply cord is used as a separator. This separator must be clearly recognisable
and easily accessible by the user. A plug connector with a CEE7/7 system is necessary.
All the electrical lines carrying supply voltage or another voltage that is dangerous in the case of con-
tact (power supply cord, alarm and indicator relays), must additionally be equipped with double or rein-
forced insulation (EN 61010-1). This can be ensured by using plastic-sheathed cables, a second insu-
lation (e.g. flexible insulating tubing), or correspondingly suitable lines with reinforced insulation.
The connecting cables can be equipped, for example, with flexible insulating tubing.
The additional flexible insulating tubing must withstand the electrical and mechanical stresses which
can occur during the intended use (see EN 61010-1, Clause 6.7.2.2.1).
DANGER!
Supply voltage!
When wiring the connecting lead, it must be ensured that the double or reinforced insulation be-
tween the electric circuits that are dangerous in the case of contact and the contactable secondary
circuit remains maintained.
NOTE!
The additional insulation must be suitable for a test voltage of 1500 V alternating current.
The thickness of the insulation must be at least 0.4 mm.
E.g. flexible insulating tubing, type BIS 85 (Bierther GmbH).
The additional insulation of the connecting leads (mains connection, alarm and indicator relays) can
be implemented as follows:
(1) - Terminals (connectors)
(2) – Flexible insulating tubing for the connecting leads
(3) – Connecting cable

10.1.1 Prevention of electrostatic discharge (ESD)
Danger!
Damage through ESD possible
The device contains electronic components which may be sensitive to electrostatic discharge
(ESD). The contact with electrostatically-charged persons or objects compromises these compo-
nents. In the worst case, they are immediately destroyed or will fail subsequent to the start-up.
Observe the requirements stipulated in EN 61340-5-1 to minimise or prevent the possibility of
damage through sudden electrostatic discharge. Please also make sure not to touch the electronic
components while supply voltage is applied.
Basics
In order not to cause damage through incorrect handling during the intervention in electronic devices,
the protective measures regarding the prevention of electrostatic charges need to be observed in com-
pliance with the DIN EN 61340-5-1, IEC 63140-5, and DIN EN 100 015 standards.
Through this, the development of electrostatic discharges and the related damage to the device can
be prevented.
Measures
As soon as the housing of the METPOINT®BDL compact is opened for service measures, the follow-
ing protective measures must be undertaken und the corresponding protective media must be used.
• Use an ESD mat with an earth connection
• Use a wrist strap
• Discharge tools prior to using them by rubbing them over the ESD mat.
