function relay REL 1
The relay REL 1 indicates violation of the limit. You can choose between an impulse
contact of 3 and 60 seconds for the control of a controller or a permanent contact.
For a permanent contact there are two alternatives:
1. Analyses are performed at the set interval and at levels below the threshold, the
relay REL 1 will be deleted automatically .
2. After the limit is exceeded, no further analysis is carried out. The relay REL 1
must be deleted by pressing the RESET button. Only then next analysis is
carried out in set interval.
►
measuring parameter
The analyser can be used to limit monitoring of different water parameters.
The relevant limit is determined by the type of indicator used
