Original installation and operating instructions
CONTENTS
Page
1. Symbols used in this document
The safety instructions in the installation and
operating instructions for the lifting station and the
appliances connected must also be observed.
2. Product introduction
The LC A1 alarm device is designed for stopping
washing machines or dishwashers to prevent
flooding.
3. Applications
The LC A1 is intended for the monitoring of pumping
stations and small lifting stations.
A level switch, installed in the appliance to be
monitored, will be activated for example in case of
overflow due to pump failure or clogging. The unit
will sound an alarm.
3.1 Construction
The LC A1 consists of a plug housing with integrated
socket. The socket can be used as a power supply
for other appliances.
The unit is mains-powered by means of a
short-circuit-proof safety isolating transformer.
The voltage for the control relay (normally open
contact) is below 24 V.
The LC A1 has a potential-free signal output.

4. Installation
1. Install the level switch. See examples on
page 91.
2. Remove the four screws at the back of the LC A1
and lift off the cover carefully.
3. Disconnect wires, if any, to the buzzer.
4. Remove the cover.
5. Lead the level switch cable through a suitable
cable gland and connect the conductors to the
terminal block.
6. Tighten the cable gland by hand.
7. Follow the same procedure for the alarm relay.
8. Connect the buzzer by means of the connector.
9. Fit the cover.
10. Fit and tighten the four screws.
5. Examples of systems
See page 91.
6. Level switches
6.1 Float switch
Float switch, type MS2, for installation in tanks and
pits. It is especially suitable for Liftaway B,
Liftaway C 100, Unilift and PUST.
Fig. 1 Float switch
91427145: Float switch with 5 m cable.
91427146: Float switch with 10 m cable.
91427147: Float switch with 20 m cable.
6.2 Vertical level switch
Level switch for installation in the cover of small
lifting stations and tanks. It is especially suitable for
Sololift2 C-3, Sololift+ C-3 and Liftaway C.
Fig. 2 Vertical level switch
97775337: Vertical float switch with 10 m cable.
Warning

7. Electrical connection
Figure 3shows the position of the terminal blocks for
the control relay (connection of level switch) and the
alarm relay.
Fig. 3 Control and alarm relays
The socket function can be set at the terminal block.
See fig. 4.
•Cont.:
The socket is used as a feed-through socket.
• NO (normally-open contact):
The socket will be switched on in case of fault.
• NC (normally-closed contact):
The socket will be switched off in case of fault.
This is the default setting for stop of a washing
machine.
