2. Introduction

Speed meters of series SD, SA and SR have been designed to close a gap with multiple speed

measuring applications, which cannot be accomplished by normal industrial tachometers.
A continual demand for increasing production speeds and higher precision at the same time

results in counting frequencies exceeding the conventional frequency range.
Particularly with fast running machines it is most important to also get fast response of the
switching outputs or the analogue output.
Many applications require to evaluate the signals of two incremental measuring systems, and

to compare the results with respect to the sum or the difference or the ratio of the two speeds.
The latter is e.g. required to indicate the diameter of a winding roll by sensing the line speed

and the roll rpm.
Other applications with food processing or process technology need to record the speed in a

reciprocal way (i.e. baking or processing time calculated from the actual speed)
And still there exist applications where the use of traditional thumbwheel switches offers real
advantages compared to keypad and menu operations.

These are some of the reasons why the new indicator series SD / SA / SR have been designed.

This manual at first provides all

basic instructions

for operation of the

counter models presented in the previous chapter

For operation of relay outputs and thumbwheel switches (if applicable)

please observe the supplementary instructions given in the appendix

For easy PC setup and PC communication with SD and SA counters,

please use our “OS32” operator software (free of charge, download from

our homepage

www.motrona.com

Where you like to have free serial access to the unit by PLC or IPC or by a

remote operator terminal, please observe the serial protocol details
described in our separate manual “Serpro”

Subsequently the manual uses the expression SD340 as a replacement for

all available models. However, statements are fully valid for the other
models too, except where especially remarked.
