ENGLISH
Alarm (terminals 14, 15, 16):
Connection for the high-water alarm, potential-free change-
over contact,
•min. contact load 12 V DC, 10 mA,
•max. contact load 250 V~, 1A,
e.g. for connecting a horn, flashing light or alarm switchgear
(at potential-free input).
In the case of an alarm, the contact is closed between termi-
nals 15 and 16.
GL (terminals 5, 6):
Connection for float switch for switching the base-load pump
SL (terminals 7, 8):
Connection for float switch for switching the peak load pump.
HW (terminals 9, 10):
Connection for high water float switch, as well as for forced
switch-on of the pump.
WSK pump 1 (terminals 1, 2):
Connection for the motor protection WSK (thermal winding
contact) for pump 1. The factory installed bridge is to be
removed when the pump is connected with the thermal win-
ding contact with cable.
WSK pump 2 (terminals 3, 4):
Connection for the motor protection WSK (thermal winding
contact) for pump 2. The factory installed bridge is to be
removed when the pump is connected with the thermal win-
ding contact with cable.
•After the electric connections are completed, put the upper
part of the housing carefully on the bottom part. Tighten the fix-
ing screws again.
8. COMMISSIONING
Prior to commissioning the pump system with the EC-Drain LS2
switchgear, check all settings such as
•Voltage selection
•DIP switch settings (see 6.2.3 and 6.2.4) and the setting of the
nominal pump current (see 6.2.3),
•Follow-up time (see 6.2.5).
Direction of rotation check for (three-phase) version only:
•If the phase sequence is incorrect, there is an acoustic signal
as well as an optical display by the flashing of all LEDs in
sequence in an anti-clockwise direction (running lights) and
the collective fault signal is active.
NOTE: To protect the pump from rotating in the wrong
direction, automatic start-up or switching on by hand is
not possible when the direction of rotation check is trig-
gered.
If the direction of rotation is wrong, exchange two phases with
each other.
Inserting the rechargeable battery (accessory)
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 insert the rechargeable battery, switch the device so
it is voltage-free and secure it against being switched
on again without authorisation.
•Insert the rechargeable battery in the provided holder. Make
sure the polarity is correct.
•Fasten the rechargeable battery with the enclosed cable tie
(Fig. 2, item 4).
NOTE: The rechargeable battery must be fully charged
at the time of commissioning or must be charged for
24 h in the switchgear.
9. MAINTENANCE
Have maintenance and repair work carried out by qualified
skilled personnel only!
DANGER! Risk of fatal injury!
There is risk of fatal injury due to electric shock when
working on electrical equipment.
•The system should be electrically insulated and
secured against unauthorised switch-on during any
maintenance or repair work.
•Damage to the connection cable should always be
rectified by a qualified electrician only.
If the switchgear is used in sewage lifting units, maintenance is
to be carried out by skilled personnel in accordance with EN
12056-4. The maintenance intervals must not exceed:
•¼ year in the case of commercial companies
•½ year for systems in multi-family houses
•1 year in the case of systems in single-family houses.
•The system operator must make sure that all the maintenance,
inspection and installation work is done by authorised and
qualified personnel, who have acquainted themselves suffi-
ciently with the system through a detailed study of the installa-
tion and operating instructions.
•Carry out a visual inspection of the electric section.
NOTE: When drafting a maintenance plan, expensive
repairs can be avoided and a fault-free operation of
the system can be achieved with a minimum of main-
tenance effort. The Salmson after-sales service is avail-
able for commissioning and maintenance work. A
maintenance report must be issued.
