•after 1 s, when the current falls short of 300 mA when the pump
is switched on.
Deactivation takes place according to a triggering curve
stored in the software. After each excess current tripping, the
error must be acknowledged with the Reset button.
If the DIP switches 1 to 5 are in the OFF position, the lowest cur-
rent value of 1.5 A is set. If one or several DIP switches are
pushed to the ON position, the value of the respective DIP
switch (table below) must be added to the basic value of
1.5 A.
Test run (DIP 6)
To avoid relatively long idle times, a cyclical test run is pro-
vided. The test run is activated / deactivated via DIP switch 6
(ON/OFF).
A test run takes place for 2 s after the pump has been idle for
24 hours.
Buzzer (DIP 7)
The internal buzzer is activated/deactivated with DIP switch 7
(ON/OFF). If the voltage fails or if the main switch is switched
off, the buzzer cannot be deactivated via the DIP switch. Here,
the rechargeable battery (accessory) is to be removed from its
holder, if necessary.

DANGER! Risk of fatal injury!
When working on the open switchgear, there is a dan-
ger of electric shock from touching the live compo-
nents.
The work may only be carried out by skilled personnel.
To change the DIP switch settings, switch the device so
it is voltage-free and secure it against being switched
on again without authorisation.
Maximum system parameters (DIP 1-3)
DIP switches 1 to 3 can be activated (ON) to prevent a possible
overload and premature system failure. When activated, the
software monitors that the preset system parameters are main-
tained. The functions can be activated either individually or
together.
An optical signal is output (yellow LED) when the factory preset
values have been exceed (Fig. 1, item 13). An acoustic alarm
signal is not output and the collective fault signal contact
(SSM) is not active.
If an optical signal is output it is recommended to check the
system or operating conditions.
Meter reset is to be carried out by qualified personnel.
The following functions can be activated (ON) or deactivated
(OFF):
Service (DIP 4-5)
The service interval for the system can be set via DIP switches 4
and 5. If both DIP switches are deactivated (OFF), no service
alarm is output.
An optical signal is output (yellow LED) when the set service
interval has elapsed (Fig. 1, item 13). An acoustic alarm signal
is not output and the collective fault signal contact (SSM) is not
active.
In order to increase operating safety, it is recommended to
carry out maintenance when an optical signal is output.
Time is recorded continuously when the mains voltage is
switched on.
Meter reset is to be carried out by qualified personnel.
The following service intervals can be selected:
Pump activation (DIP 6-7)
Switches for selecting the pump operation mode. Each pump
can be deactivated (OFF) or enabled (ON) here. The green
LED (Fig. 1, item 5, item 9) lights up while the pump is in opera-
tion.
NOTE: If switched off, the pump is not switched on by
float switch requests.
6.2.5 Follow-up time (Fig. 2, item 2)
The follow-up time is the time from when the float switch con-
tact opens to the base-load pump switching off.
The follow-up time is set in the device via the potentiometer.
This is set infinitely variably within the range of 0-30 seconds.
DANGER! Risk of fatal injury!
When working on the open switchgear, there is a dan-
ger of electric shock from touching the live compo-
nents.
The work may only be carried out by skilled personnel.
To set the potentiometer, switch the device so it is volt-
age-free and secure it against being switched on
again without authorisation.
6.2.6 External motor protection, WSK
If the motor is equipped with a thermal winding contact (WSK),
it must be connected to the provided terminals 1 and 2 for
pump 1 and terminals 3 and 4 for pump 2.
For motors without a WSK, a jumper is to be wired.
6.2.7 High water alarm
In order to be able to evaluate the high water alarm, a float
switch must be connected to terminals 9 and 10 (HW). If trig-
gered, there is an optical and acoustic signal, as well as a
forced switch-on of the pump. The collective fault signal (SSM)
and high water alarm are active.

For necessary maintenance work,
each pump can also be acti-
vated or deactivated via a DIP
switch.
