In addition to the function mode of the
relay, it is also possible to select
whether the alarm output relay contact
is closed (closing function on, default
setting) when the relay is pulled in or
open (opening function) (seechapter

10.3.10 Configuration / pulse memory
If the incoming pulse rat
e is higher than the maximum pulse rate that the pump can process
(max. pump frequency e.g. 122 strokes/min at 50 Hz), the pulses that cannot be processed
can be stored.
WARNING
The stored pulses are processed once no further external pulses are received. This means
that the pump continues to function even though there is no external running condition.
In the worst case, this can lead to metering taking place into a closed system and resulting
in impermissibly high pressure in the system.
This must be prevented through appropriate safety measures.
The memory content is erased by activating the metering lock or switching off the pump.
