6.2.3 DIP switch (Fig. 2, item 1)
Danger! Danger of death!
When working on the open switchgear, there's a
danger of electric shock from touching the live
components.
The work may only be carried out by skilled per-
sonnel.
To change the DIP switch settings, switch the
device so it's voltage-free and secure it against
being switched on again without authorisation.
Internal electronic motor protection (DIP 1-5)
To protect against motor overload, the excess
current release must be set according to the nom-
inal pump current via the DIP switches 1 to 5
(1.5-12 A).
It is deactivated:
• when the set nominal pump current is exceeded.
• after 10 s, when the current falls short of 300 mA
when the pump is switched on (only for 3~ ver-
sion).
Deactivation takes place according to a triggering
curve stored in the software. After each excess
current triggering, the error must be acknow-
ledged with the Reset button.
If the DIP switches 1 to 5 are in the OFF position,
the lowest current value of 1.5 A is set. If one or
several DIP switches are pushed to the ON posi-
tion, the value of the respective DIP switch (table
below) must be added to the basic value of 1.5 A.

Pump kick (DIP 6)
To avoid relatively long idle times, a cyclical test
run is provided. The test run is activated/deacti-
vated 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.
Installation and operating instructions Wilo-Control EC-Drain LS1
The electronic excess cur-
rent release is set via the DIP
switch, and special func-
tions can be activated, such
as the pump kick and
buzzer.
1.5 A (basic value)
6.2.4 Follow-up time (Fig. 2, item 2)
The follow-up time is the time from when the
float switch contact opens to the 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! Danger of death!
When working on the open switchgear, there's a
danger of electric shock from touching the live
components.
The work may only be carried out by skilled per-
sonnel.
To set the potentiometer, switch the device so
it's voltage-free and secure it against being
switched on again without authorisation.
6.2.5 External motor protection, WSK
If the motor is equipped with a thermal winding
contact (WSK), it must be connected to the pro-
vided terminals 1 and 2.
For motors without a WSK, a jumper is to be wired.
6.2.6 High water alarm
In order to be able to evaluate the high water
alarm, a float switch must be connected to termi-
nals 5 and 6 (HW). If triggered, there is an optical
and acoustic signal, as well as a forced switch-on
of the pump. The collective fault signal is active.
7 Installation and electrical connection
DANGER! Danger of death!
Incorrect installation and inexpert electrical
connection can pose a risk of fatal injury.
• The installation and electrical connections
should only be done by properly skilled staff and
in compliance with the applicable regulations!
• Accident prevention regulations must be
observed!
7.1 Installation
Install the switchgear in a dry, vibration-free and
frost-safe location.
Protect the place of installation from direct sun-
light.
Borehole distances 140 x 219 mm (WxH). For more
information, see also bottom side of switchgear.
For fastening, provide screws (4 screws, Ø max
4 mm) and the corresponding dowels.
To fasten the switchgear, open the upper part of
the housing:
• Loosen the 4 cover fixing screws
• Fasten the switchgear to the wall with the dowels
and screws.
