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 effective 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.

In accordance with EN50081-1 and EN50082-2 for unrestricted use in housing and industrial areas

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 configured to the specific application.

Please refer to chapter "Configuration".

Safety advice

In order to exclude any risk whatsoever for the operator the following points have to be

observed:

a)Immediately switch off 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 touchproof after installation.

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).

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.

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.

Terminal assignment:

Use male plugs 1 and 2.

Supply voltage:

The display takes power directly from measuring current.

Electric connection and commissioning of the device must be carried out by trained and skilled personnel.

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 !!
