10.4.10 Configuration / Alarm output
This option allows the alarm output to be inverted (alarm output - relay has responded or not
responded in the event of an alarm).


= In the event of an alarm,
the relay for the
alarm output has responded.
(Default setting)

= In the event of an alarm,
the relay for the
alarm output has not responded.
In addition to the function mode of the relay, it is also possible to select whether the alarm
output relay contact is closed (NO function on, default setting) when the relay responds or
open (NC function) (see chapter
7.2.9 “ Hardware conversion for the alarm contact (switch
S1) ” Hardware conversion alarm contact).
10.4.11 Configuration / Pulse memory
If the incoming pulse rate is to be higher than the maximum quantity that can be metered by
the pump during this time (max. metering frequency depending on the metering mode setting
of 120, 100, 80 strokes/min), those pulses which are not processed can be stored by
activating the "Pulse memory" function.
As soon as the metering lock is enabled, the
icon appears in the display.
This icon flashes while the pump is processing pulses which have just been stored.
ATTENTION
It is possible that the metering quantity corresponding to pulses which have been saved
will only be processed once there are no external pulses being received. This means that
the pump would continue to run even though no external running conditions apply.
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 content of the memory is cleared by enabling the metering lock, through an incoming
empty signal or by switching off the pump.
