DSB data memory module
The replaceable plug and play memory device is integrated on the PCB of the control unit where all sen-
sor data such as sensor constants, model numbers, serial numbers, and so on are stored. Consequently,
the memory module is linked to the sensor. If
the transmitter’s electronics are exchanged for any reason,
the control unit BE4 must be removed from the old and placed onto the new electronic stack.
Warning
Make sure that you abide by the applicable standards and regulations pertain-
ing to electrical devices, device installation and process technology when re-
placing the transmitter electronics. The highly integrated electronic components
in the device carry the risk of ESD hazards and are only protected when in-
stalled in the device pursuant to EMC standards.
The removal and insertion of the control unit is performed as can be seen in the following sketch.
After removing 4 screws, the control unit with the display can be detached.
If the transmitter is replaced, the control unit should be transferred to the new transmitters electronic
stack. When the flow meter is powered up, the device continues using the values stored in the memory
device. Thus, the DSB memory device provides maximum safety and comfort when device components
are replaced.
The control units are not interchangeable arbitrarily between identically constructed transmitters
due to the memory device.
Replaceable circuit boards must be ordered from Heinrichs using the trans-
mitter’s serial number specification. The calibration data of the sensor are programmed into the delivered
BE4 control panel directly by the manufacturer.
