1.2 Block Diagram
1.1 Device Descripon
LS20 Controller devices are the devices that can control 3 dif-
ferent integrated relays by using data received from PS1x Limit
Switch series, PS3x Limit Switch series or LS20 Level Control
Equipments. With this data can be controlled motor, pump,
on-o valve, solenoid valve, audible or/illuminated alarm type
of three dierent devices by 3 each NO(Normally Open) +
NC(Normally Closed) relay contacts.

2.3 Assembly Environment and the Working Condions
LS20 Controller devices should be denitely used with at least
one panel protecon class IP65 or by installing within the box.
In contrary the oxidaon can occur in the electrical equipments.
Using of LS30 Controllers in medium of big evaporaon can not
be recommended from the point of life cycle.
ATTENTION : LS20 Controller should be denitely energized
while lling or draining the tank level because of needing trig-
ger to set or reset relays. In contrary it may cause overowing
or unexpected draining.

2.5 Assembly Sequencing
Place the device to the panel that has been manufactured ac-
cording to 2.2 Panel Cung Dimenons place the device by fac-
ing the screen yourself,
According to the 2.4 Mounng Type ghten the xing stands
within box by means of a suitable screw driver by installing the
side channels located at the sides of device,
In order to make the electricity connecon remove the termi-
nals at the a of device,
By means of a suitable screw driver make connecons as per 3.

3. ELECTRICAL CONNECTIONS
3.1 Basic Electrical Connecons
The electricity connecons of device should be made by an au-
thorized electrician. In addion cable connecons should be
maximum 1.5 mm2 in cross secon.

3.2 Supply Voltage Connecons
Energizing of device other than supply voltage tolerances may
severely damage the device. At connecon of devices with 220
VAC measures should be taken against electrical shock. At de-
vices with 24 VDC supply voltage, the direcons of -/+ poles
does not dierent.

3.3 Logic Input Connecons
In case of reversed operaon, the relay inputs 'start' and 'stop'
posions should be changed. For alarm applicaons. In alarm
applicaons, buon switch can be used instead of limit switch-
es for manual stop operaon. ('COM' and 'Stop' inputs).
