ENGLISH
If "manual error acknowledgement" is
set to 'Yes' then press the OK button to
restart the pump.
∙ Short-term operation (S2 time)
When the pump is not submerged, it
operates only for a preset period (max-
imum running time). This is to prevent
the temperature of the motor from ris-
ing above its maximal permissible op-
erating temperature. The value for the
maximum permissible running time can
be found in the technical data provided
with the pump. The subsequent resting
time (restart lock-out), during which the
pump remains switched off, must be
long enough to allow the motor to cool
down to the ambient temperature. This
is generally equal to the operating time
multiplied by a factor of five.
∙ Intermittent duty (S3 time)
The pump operates only for a short pe-
riod before being switched off again if it
is not submerged. The switch-on and
switch-off times are expressed as per-
centages of 10 minutes, e.g. for an S3
time of 30%, the pump is switched on
for not longer than 3 minutes and then
switched off for 7 minutes. This operat-
ing mode ensures that the pump does
not overheat.
Follow-up time
The follow-up time is the time for which
the pump continues to run after the
switch-off level has been reached, to
ensure that the pressure sensor hangs
free of the remaining wastewater in the
chamber. This is important because it
prevents the measuring system from
becoming soiled. If the “Static pressure
sensor” setting has been selected, the
available options are: “Standard”, “Au-
tomatic parameterisation” and “Auto-
matic”. If the “Pressure switch” and “KT
switch” setting has been chosen, only
the “Standard” setting is available.
∙ “Standard” setting: When the wa-
ter level drops below the switch-off
level, the pump does not switch off
immediately, but continues to run for
the time specified here. Adjustment
range: from 0 to 120 seconds!
∙ “Automatic” setting (static pressure
sensor only): The time required for
each pumping operation is recorded
and compared with a stored value,
and adjusted if necessary.
∙ "Automatic parameterisation” set-
ting: (static pressure sensor only)
The follow-up time is determined
here from the first three pumping
procedures.
ATTENTION! The switch-off point for
explosion-protected submersible mo-
tor pumps must not be at a lower depth
than the upper edge of the volute cas-
ing in order to comply with EU Directive
2014/34 EC. The pump must not draw
in air!
The correct follow-up time can be de-
termined only by carrying out several
trial runs with the system!
The final running time of the pump can -
not be correctly determined until the
pressure line is full of wastewater.
When using the “Automatic follow-up
time” function, make sure that the
air-pressure sensor of the static pres-
sure sensor is installed at a height of
exactly 10 cm above the volute casing
of the pump. A test run must be carried
out to check that the follow-up time
function operates correctly.
Start-up delay
This is for maintaining staggered oper-
ation in areas with only a limited power
supply.
­­­­­ FORCED SWITCHING ON ­­­­­
Test run
To prevent the pump from seizing up, it
can be started up briefly at regular in -
tervals. The start of the pumps takes
place 1 to 7 days after the last pump run
for 1 to 5 seconds. If the water level is
measured using level sensors, the test
run will only be carried out if the water
level lies above the switch-off level.
In order to avoid unnecessary loading of
energy use, the pumps are started with
at least an 8-second interval from one
another in the test run.
For control units with digital level
measurement (submersible /pressure
switches), it must be noted that a cer-
tain amount of water will always be
pumped, even if the pump is switched
on for just a second. This means that
if no water flows into the chamber, but
continued test runs are carried out, the
pump could end up operating in “snore”
mode.
This would mean non-compliance with
explosion protection regulations and
could also result in the need for a ser-
vice operative to be called out to bleed
the air from the pump.
Automatic pumping out
(only for SM and) This function only
makes sense with continuous lev-
el measurement. Some installations
may require media to not remain in the
chamber for too long, or it to be pumped
into the overall system at a specif-
ic time. In addition, with low inflow, it
can ensure that open level sensors are
freed from obstructions at regular in-
tervals (setting 1-99 hours).
­­­­­ ALARM -----
Acoustic alarm
If this function is enabled, the integrat-
ed alarm buzzer will be sounded when
an error occurs. Options: Yes / No.
If an error is acknowledged with the OK
button, the alarm will stop buzzing but
the relay contact will remain active. By
pressing the OK button a second time,
the relay will be reset, provided that the
error no longer exists.
Alarm relay flashes
You are able to select here whether the
non-isolated alarm relay switches at
one-second intervals when a fault oc-
curs or whether it remains on all the
time: Yes = Relay switches at one-sec-
ond intervals, No = Relay with continu-
ous contact.
Delay for alarm relay
To prevent the alarm from being trig-
gered for errors of short duration, a
time delay can be set here for switch-
ing the non-isolated and potential-free
alarm contacts. Setting range from 1 to
60 seconds. A value of 0 minutes deac-
tivates this function!
AUX logic
"AUX in switch logic" is configured as
normally closed or normally open.
AUX influence
"Aux influence" can be used to select
whether an alarm switches off one or
both pumps ("P1 OFF," or "P2 OFF") or
does not have any effect ("None"). In ei-
ther case, the triggered alarm appears
in the display and activates the poten-
tial-free and non-isolated alarm relays
as soon as the alarm delay time has
expired.
