Danfoss MBD 1000 Installation guide
Connection and operating instructions
Plug-in Display MBD 1000
Introduction
The MBD 1000 is a microprocessor controlled
plug-in display that can be universally applied to
all MBS, AKS and MBT transmitters with a
4-20 mA output. The display provides a simple
and eective solution for local monitoring of
pressure and temperature. It does not require its
own auxiliary voltage source but can be supplied
directly from the measuring current.
The measuring value is displayed on a 4-digit LCD
with the max. display area ranging from
−1999 to +9999 digits.
The operating range of the display device can
be directly adjusted to the transmitter range by
simply entering the maximum and minimum
measuring range limits as well as the decimal
point position.
Parameters and limit values are entered via
three keys which are accessible after removal of the
cover.
All programmable parameters of the MBD 1000
are stored in an EEPROM; in the event of a
current failure they will remain there for at least
10 years.
The MBD 1000 is equipped with a self-diagnosis
system which continuously monitors the
essential parts of the device.
Sensor operational performance is continuously
monitored.
The MBD 1000 is tested and completely
calibrated.
The MBD 1000 must be congured to the specic
application.
Please refer to chapter "Conguration".
In accordance with EN50081-1
and EN50082-2 for unrestricted
use in housing and industrial
areas
Safety advice
In order to exclude any risk whatsoever for the
operator the following points have to be
observed:
a) Immediately switch o the unit in the event
of visible damage or obvious malfunction.
b) Always disconnect the MBD 1000 before
opening it up. All electrical connections
must be securely connected and touch proof after installation.
Attention: When running electric devices parts of these devices will always be highly
energised. Unless the warnings are observed serious personal injuries or damage
to property may result. Skilled personnel only should be allowed to work with this
device. For trouble-free and safe operation of the device please ensure professional
transport, storage, installation and connection as well as proper operation an maintenance.
c) Standard regulations for operation and
safety for electrical, light and heavy current
equipment have to be observed, with
particular attention having to be paid to
national safety regulations (e.g. VDE 0100).

MBD 1000 Connection and operating instructions
Electric connection
The MBD 1000 is simpy plugged into a transmitter by means of a special adaptor for the cubic
plug according to DIN43650.
Electric connection and commissioning of the
device must be carried out by trained and skilled
personnel.
Terminal assignment:
Use male plugs 1 and 2.
Supply voltage:
The display takes power directly from measuring
current.
Assembly
Wrong connection may lead to the destruction of
the display device. Danfoss cannot assume any
responsibility for this !!
Observe the maximum input current rating of
40mA under all circumstances !!
