6 Operation, maintenance and repair

6.1 General rules

DANGERLife-threatening injuries from electric shock▶ Switch off power supply.▶ Secure power supply against inadvertent switch-on.▶ Check that power supply is free of voltage.

DANGERLife-threatening injuries from ignition of explosive atmospheres▶ Wait 20 minutes before opening the housing until the capacitors have discharged

and components have cooled off.▶ Avoid electrostatically charging the device, e.g. by rubbing it with dry cloths or by

impact.

Modifying the Coriolis mass flow meter as well as using unauthorized parts is prohibitedand will void the certification.

▪ The locking screws of the covers may be loosened and tightened only with an Allenwrench.

▪ After closing and before commissioning, it must be checked whether the lockingscrews are tightened and the covers are closed.

8.3 Ex code

The Ex code, in combination with the model code positions 2 and 10, allows determiningthe maximum process fluid and ambient temperatures for every temperature classaccording to the Ex certificate. In each case, it is located on the additional nameplate ofthe sensor, except for Rotamass Nano and all high-temperature versions. No Ex code isavailable for these devices so that the process fluid temperature ranges must be takendirectly from the chapter Temperature specification by temperature classes. [} 54]

8.3.1 Determining the maximum temperatures based on the Ex codeThe specific example below is intended to explain how to determine the maximumprocess fluid- and ambient temperatures based on the Ex code and the model code.

The complete tables of the process fluid temperature range are listed in the "Annex 1" ofthe IECEx certificate. Option L␣␣␣ or Y␣␣␣ determines table a or b for remote variants.This example presents only excerpts thereof.

The following steps are performed to determine the maximum temperatures:

▶ Determining the maximum process fluid temperature Tpro,max based on the Ex code,positions p6...p2

▶ Determining the maximum ambient temperature Tamb pre based on the followingcriteria:

– model code position 2 and 10– Ex code, position a– Determined maximum process fluid temperatures Tpro,max

Determining themaximum processfluid temperatureTpro,max

The values of the Ex code on the nameplate p6 – p2 are the line indexes that determinethe maximum process fluid temperatures Tpro,max according to Table 6 in the Ex certificate.The temperature class determines the applicable column.

For the temperature classes, this results in the following values for the maximum processfluid temperature:

▪ Temperature class T6 (column T6) and value of Ex code p6 (value = 68) define theintersection: Tpro, max = 49 °C






These maximum process fluid temperatures established must be used for further determi-nation of the ambient temperatures.

First, the correct product-dependent table for the ambient temperature must be identified.To do so, the values of the positions 2 and 10 of the model code on the nameplate arecompared with the information of the table titles in Table 7 – 11 of the annex to the Excertificate. A match determines the table to be applied.

In this case table 9a is valid, because no option Y␣␣␣ is present in the model code. Thefirst digit of the Ex code, a = 3, defines the applicable columns T6 – T1 within the locatedambient temperature table.

The maximum process fluid temperatures Tpro,max established define the applicable lineswithin the located ambient temperature table. If a value of the maximum process fluidtemperature is not listed in the table, the next higher temperature value is used.
