analysis interval
There are four fixed interval times selectable by varying the position of switch S1
and S2.
The choice of analysis interval determines the frequency at which analyses are
carried out. The interval time is the time interval between two measurements.
If the potential-free input "flow switch" is open, no analysis is carried out.
→ When delivered, the switch is bridged
→ Analyses are performed in a set interval
→ Make sure that the switch is either jumpered properly, or an external signal is
issued.
NOTE
►
retry cycle
It can be determined whether a second analysis should be carried out to verify the
result of a failed test by utilising the retry function. Only when two consecutive
analyses indicate bad water conditions, will the relay REL1 be activated.
This second analysis is carried out independently of the set interval app. 4 minutes
later
