→ The delay time must be calculated on site since it will depend on the water
temperatures, the water pressure and the flow conditions of the system.
Always begin with a higher delay time and adjust accordingly.
►
analysis interval
There are four fixed interval times selectable by varying the positions of switches 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.
→ When input ‘IN’ is open circuit, analysis start is disabled. The unit is delivered
with terminals 16 / 17 bridged. Ensure that this bridge is in place or, alternatively,
connect an external switch (e.g. flow monitor).
→ Input ‘IN’ can be switched over from flow-monitor function to start function by
means of S10 (S10 = ON). Only the intervals 30, 60 und 120 minutes apply to the
start function. If S1 and S2 are OFF, auto-start is disabled.
NB!
The external start is disabled when input ‘IN’ is bridged.
→
(∞)*When the programme switches S1 und S2 are OFF, and S10 is ON, the interval function is deactivated.
►
analysis repetition
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. (first result suppression). 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 approx. 4 minutes
later. If a flow monitor is connected to terminals 16 / 17 (IN) the 2
nd
analysis will be
carried out even when no flow has been detected.
