The number of read-outs per day via the optical interface is limited. During daily read-out at least 4
communications are possible. If read-outs are carried out more rarely, the possible number of communications will
increase.
10.2 Retrofitting with an additional communication interface (optional)
We also offer a retrofittable meter to which communication interfaces can be added later. You will find the
description of our optional interfaces in the operating instructions „Communication Interfaces S3(C)“.
To retrofit such a meter with an additional communication interface the calculator´s adhesive seal has to be
destroyed and the device´s calculator to be opened.
When the calculator is open please observe the ESD
requirements according to EN 61340-5-1.
Use a screwdriver with a wide tip (4 - 5 mm) and carefully press in the two round predetermined breaking points
above the cable feedthroughs (see picture 1).
Then insert the screwdriver into one of the two openings at an angle of approx. 45° and carefully lift the handle up
to approx. 90° (see picture 2). The upper housing piece of the calculator is then no longer latched on this side.
Repeat this with the other opening. Now the upper housing piece can be taken off.
Plug the interface module on the right side of the PC board. The cables are to be fed through the rightmost cable
feedthroughs into the calculator after removing the blind grommets. Close the calculator.
Protect the calculator against unauthorized opening using one of the numbered adhesive seals enclosed to the
modules (stick it upon the seal destroyed). The added bar code label can be used for the purpose of
documentation.
