MemoLink Basic safety instructions
Endress+Hauser 5
2 Basic safety instructions
2.1 Requirements for personnel
• Installation, commissioning, operation and maintenance of the measuring system may be
carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the specified
activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions and
must follow the instructions contained therein.
• Faults at the measuring point may only be rectified by authorized and specially trained
personnel.
Repairs not described in the Operating Instructions provided must be carried out only
directly at the manufacturer's site or by the service organization.
2.2 Designated use
Memobase Plus is a measurement and calibration software offering central database
management for sensors incorporating Memosens technology. It can be used to calibrate,
adjust and manage sensors in a laboratory.
Memobase Plus is designed for use in the following applications:
• Laboratories
• Process-oriented workbench applications in non-hazardous areas
Memobase Plus cannot be used to replace a process transmitter, as communication with
the control system is not supported.
MemoLink acts as the Memosens/USB interface converter for the Memobase Plus software.
MemoLink supports Memosens sensors with Ex approval and without Ex approval.
Recommended areas of application are preferably laboratory applications for calibrations and
functional testing.
Use of the device for any purpose other than that described poses a threat to the safety of
people and of the entire measuring system, and is therefore not permitted. The manufacturer
is not liable for damage caused by improper or non-designated use.
2.3 Workplace safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations
• Regulations for explosion protection
2.4 Operational safety
Before commissioning the entire measuring point:
1. Verify that all connections are correct.

Basic safety instructions MemoLink
6 Endress+Hauser
2. Ensure that electrical cables and hose connections are undamaged.
3. Do not operate damaged products, and protect them against unintentional operation.
4. Label damaged products as defective.
During operation:
‣If faults cannot be rectified:
products must be taken out of service and protected against unintentional operation.
2.5 Product safety
2.5.1 State-of-the-art technology
The product is designed to meet state-of-the-art safety requirements, has been tested, and
left the factory in a condition in which it is safe to operate. The relevant regulations and
European standards have been observed.
2.5.2 Electrical equipment in hazardous areas
• The MemoLink must never be used in hazardous areas! The MemoLink is not designed as a
field device for installation in industrial environments.
• The MemoLink, which is approved in accordance with EC type-examination certificate BVS
12 ATEX 079 X, ensures that the "intrinsic safety" type of protection of the Memosens
measuring cable and the Memosens sensor is not compromised during calibration and
functional testing.
• The computer, USB cable, MemoLink, Memosens measuring cable and Memosens sensor
must be located outside the hazardous area during calibration and functional testing.
• Memosens cables with Memosens sensors may be connected to the Memosens interface of
the Memolink.
• The internal electronics of the Ex-approved Memosens/USB interface converter MemoLink
makes it possible to connect Ex-approved and non-Ex-approved, passive Memosens
measuring cables with Memosens sensors. The connection of non-Ex-approved Memosens
sensors does not interfere with the intrinsic safety of Ex-approved Memosens sensors
connected at a later stage.
• Information on the applicable standards, directives and other regulations can be found in
the EU Declaration of Conformity and the relevant certificates.
• MemoLink may only be connected to the USB interface of a commercially available
computer.
If cables with Ex approval are used in combination with sensors without Ex approval, it is
possible to continue using the cables in combination with Ex-approved sensors on
Memobase Plus. The sensors do not lose their Ex approval. The cables may not be used
subsequently in a hazardous zone.
2.5.3 IT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any
inadvertent changes to the device settings.

MemoLink Product description
Endress+Hauser 7
IT security measures in line with operators' security standards and designed to provide
additional protection for the device and device data transfer must be implemented by the
operators themselves.
3 Product description
3.1 Product design
1 to 4 MemoLink sensor terminal boxes, with the same number of Memosens sensors (1 to
4), can be connected per license.
The following components are required in each case:
• Computer with the Memobase Plus software installed (not supplied)
• 1 USB cable
