Switched-on time ". If a considerable difference between the pumps is
determined, it means the capacity of one of the pumps must have
fallen considerably. This information can be consulted for diagnosis
and service, e.g. to recognize plugged-up filters or worn out bearings.
S
ince in this case all pumps are operated alternately in the same area,
their switch-on and switch-off points should theoretically be set the
same. However, this would cause all relays to always switch on or off
together. To achieve suitable switching characteristics, one relay must
be assigned the desired switching points; the other relays are
assigned switching points that are never reached in normal operation,
e.g. 110 % and -10 %.
Note:
T
he index of the lastly switched on relay is not saved in case of voltage
loss, this means that adter switching on the signal conditioning
instrument, always the relay with the lowest index starts.

.4 Tendency recognition
T
he function of the tendency recognition is to recognize a defined
change within a certain time period and to transfer this information to a
relay output.
T
he information for tendency recognition is generated out of the
measured value change per time unit. The output variable is always
the measured value in percent. The function can be configured for
rising and falling tendency. The actual measured value is determined
and summed with a sample rate of a second. After the max. reaction
time, the average value is generated out of this sum. The real
measured value change results then of the newly calculated average
value less the previously calculated average value. If this difference
exceeds the defined percentage value, the tendency recognition
responds and the relay deenergises.
Note:
T
he activation and configuration of the tendency recognition requires
PACT
ware with the suitable DTM. Setting parameters via the
integrated indicating and adjustment unit is not possible.
