4 Working with the master
Process sequence
At the set start-up time the first valve regulates its flow to the set flow rate , in the
shown example to 200l/h.
Then the second valve regulates its flow, followed by the other valves, and finally the pro-
cess is repeated until all valves reach the set flow rate or the 4 hours have passed.
If the temperature lower limit (here: 50 °C) is fallen below, an error message appears
and an entry is made in the error log.
If the temperature upper limit (here: 90 °C) is exceeded, an error message appears
and an entry is made in the error protocol. These two limits must be defined mean-
ingfully, since they form the basis for an evaluation of the
protocols .
If the checkmark at Thermal disinfection (TD) is set, the parameters shown below it
are displayed and active. Thermal disinfection process see Thermal disinfection .
4.3.7 Type = Constant
In this type, the opening angle set for the valve (leakage rate) is not changed.
There are also no parameters to be adjusted. The system permanently maintains the opening
angel set for each valve, for details of the setting see
leakage rate (-> settings -> valves) . Only
the weekly maintenance disrupts this state for a short period of time.
