Basic safety instructions

3.1

Requirements for the personnel

Basic safety instructions

The personnel must fulfill the following requirements for its tasks:‣ Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣ Are authorized by the plant owner/operator.
‣ Are familiar with federal/national regulations.
‣ Before starting work, read and understand the instructions in the manual andsupplementary documentation as well as the certificates (depending on the application).
‣ Follow instructions and comply with basic conditions.

3.2

Intended use

Application and measured materials
The device described in these Operating Instructions is a monitoring unit for use with theEndress+Hauser Micropilot M and Micropilot S-series radars and other HART compatible
devices. Mounted at the tank side, it provides indication of measured data, allows
configuration and supplies intrinsically safe (i.s.) or explosion proof (XP) power to theconnected sensors on the tank. Various industry standard digital gauging communication
protocols support integration into open architecture tank gauging and inventory systems.
Measuring devices for use in hazardous areas, in hygienic applications or in applications
where there is an increased risk due to process pressure, are labeled accordingly on the
nameplate.
To ensure that the measuring device remains in proper condition for the operation time:‣ Only use the measuring device in full compliance with the data on the nameplate and thegeneral conditions listed in the Operating Instructions and supplementary documentation.
‣ Check the nameplate to verify if the device ordered can be put to its intended use in theapproval-related area (e.g. explosion protection, pressure vessel safety).
‣ If the measuring device is not operated at atmospheric temperature, compliance with therelevant basic conditions specified in the associated device documentation is absolutely
essential.
‣ Protect the measuring device permanently against corrosion from environmental
influences.
‣ Observe the limit values in the "Technical Information".
The manufacturer is not liable for damage caused by improper or non-designated use.

3.3

Workplace safety

For work on and with the device:‣ Wear the required personal protective equipment according to federal/national
regulations.

Designation of the digital inputs or outputs (examples)• Each Digital IO Module provides two digital inputs or outputs.
• In the operating menu each input or output is designated by the respective slot and two
terminals within this slot. A1-2, for example, denotes terminals 1 and 2 of slot A. The same
is valid for slots B, C and D if they contain a Digital IO module.
• For each of these pairs of terminals, one of the following operating modes can be selected in
the operating menu:• Disable• Passive Output• Passive Input• Active Input
