Configuration / Low-level contact

This function specifies whether an open or a closed contact at the level input
(plug I, see chapter 7.2.2) is regarded as level OK.

Selecting

10.3.9

Configuration / Alarm output

This option permits the inversion of the alarm output (alarm output relay has pulled in or not
pulled in when the alarm was triggered).

Conversion from alarm relay mode to contact mode.

See chapter

10.3.10 Configuration / pulse memory

If the incoming pulse rate 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.
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.
WARNING
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.

 = contact open:
level not OK (empty)
contact closed:
level OK (full)
(Default setting)
⚫ = contact closed:
level not OK (empty)
contact open:
level OK (full)
⚫ = When an alarm is triggered, the
relay is pulled in for the alarm
output. (Default setting)
 = When an alarm is triggered, the
relay is not pulled in for the alarm
output.
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) (see chapter
