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.

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.

3.4 Relay Output Connecons
Devices which draws heavy current and are coiled such pump
controlled by relay outputs, solenoid valve or siren should nec-
essarily be controlled in indirect way by means of auxiliary re-
lay and contactor. Otherwise, failure to do so may cause relay
contact to malfuncon or cause the device, which must be sup-
posed to work but due to the contacng point, to stop its op-
eraons and cause serious damage to the system (for example,
overows of tank).
NOT : It has been drawn by considering that all of equipments of con-
necon schemac are operang with 220 VAC power. According to dif-
ferent power values connecon way may vary.

3.5 Cabling
Cable connecons should be maximum 1.5 mm2 cross secon.
Otherwise the clamp connecons may not be possibly done.
In general cabling, mul-wire and nned cables should be pre-
ferred to extend the operang life of the device and reduce the
possibility of contact failure caused by oxidaon. PS1x / PS3x
Limit Switch connecons to be made to logic inputs can use 2
x 0.75 mm2 cross-secon cables. LS20 Level Controllers must
be selected according to the number of contacts as they are
custom made specically for the applicaon.
4. START UP
The LS20 Controller can operate without any programming pro-
cess when the electrical connecons are made correctly. In the
screen, there are red - green LEDs only showing the operang
status of the output relays. In this way, the working and stopped
devices can be monitored.

LS20 Controllers' work logic is just to seal the output relays.
When the signal is received by "Start" input, the corresponding
relay is set and sealed and the connected device starts to work.
When the signal is received by “Stop” input, the relevant relay
is reset and sealing is broken and the connected device ends its
operaon.
LS20 Controllers must be energized when there is discharge or
lling at the tank, as they receive level informaon instantane-
ously. Otherwise, the level change may not be detected, so it may
be the case that the tank is overowed or discharged at an unde-
sirable amount.
LS20 Controllers can be energized aer the electrical connecons
are completed as per arcle "3. ELECTRICAL CONNECTIONS”. In
case that LS20 Controller devices and Limit Switches such as PS1x
/ PS3x other than LS20 Level Controllers will be used, it may be
necessary to send informaon to detect the level informaon af-
ter the inial power up. In the working scenario, aer the rst
energy is supplied;
If a device that needs to be run is not working, then apply an ex-
ternal magnet or the magnet side of water-gauge located in the
devices of Level Indicator of MLG Series into the “Start” or (for
example if solenoid valve does not funcon and in case that it is
controlled by the Relay 2 at LS20 Controller) into “Start 2” input
into the body of PS1x/PS3 in the manner almost to touch it;
check whether the device, that you wanted see working, does
work or not.
•

LS20 CONTROLLER INSTALLATION AND OPERATING GUIDE 15
In case that a device, which was not supposed work, is working;
then apply an external magnet or the magnet side of water-
gauge located in the devices of Level Indicator of MLG Series
into the “Stop” input or (for example if pump is working and in
case that it is controlled by the Relay 1 at LS20 Controller) “Start
1” input into the body of PS1x/PS3x Limit Switch in the manner
almost to touch it; check whether the device, that you do not
want to see it working, stop to work or not.
Once these operaons are done correctly, the LS20 Controller
will not have to be intervened again. In case of long-term en-
ergy interrupons, re-commissioning may be necessary.

5. MULFUNCTION
5.1 Mulfuncon Dedecon
In case that the device(s)
to be controlled did not
work even aer you made
the electric connecons of
LS20 Controller as per ar-
cle “3. ELECTRICAL CON-
NECTIONS”;
Please read carefully the arcle
“4. START UP” and make sure
that the device is to detect level
informaon correctly.
In case that the device(s)
to be controlled are work-
ing connuously even aer
you made the electric con-
necons of LS20 Controller
as per arcle “3. ELECTRI-
CAL CONNECTIONS”;
Please read carefully the arcle
“4. START UP” and make sure
that the device is to detect level
informaon correctly.

LS20 CONTROLLER INSTALLATION AND OPERATING GUIDE

In case that none
of the LEDs at
the screen does
not work even
aer you made
them energized;
Make sure that supply voltage reaches
to LS20 Controller. If the energy correctly
reaches to the Controller, LS20 may be out
of order. Pass through arcle 5.3.
In case that
devices con-
nected to the
LS20 Controller
even when the
level at the tank
changes;
Check the status of relays by means of Sta-
tus LEDs at the screen. Make sure that the
LED of Start connected to the malfuncon-
ing device is on.
In case that Stop LED is on;
• Tank level may not reach to the point of
start signal. Re-check the tank.
• Make sure that the sensor connecons of
logic input are made properly, addional
make a malfuncon diagnosis as per the
arcle 5.2.
In case that Start LED is on;
• Disconnect LS20 Controller from its pow-
er source. Remove the clamp of number 1
to 10 connected to the relay output. Take
measurements from clamps 2 & 3, 5 & 6,
9 & 10 at Ω of your measuring instrument.
For all measurements, you should read a
shortcut circuit (a resistance value close to
zero).The relays connected to the clamps
that cannot be assumed as shortcut may
be out of order. Proceed to the arcle 5.3.

5.2 Determinaon of Sensor Defects
5.2.1 Determinaon of PS1x / PS3x Limit Switches Defects
There is no dierence between Limit Switches of PS1x and ve
PS3x Series in terms of their electrical structures. Only their
mechanical properes or their connecon types to the MLG
Series Level Indicators may vary. The PS1x and PS3x Series
Limit Switches are available with plug-in or cable connecons
(see "PS Series Limit & Bistable Switches Installaon and Op-
eraon Manual" for connecon and contact features).
Limit Switches only provide contact when they are at the same
point as the level amount. When the level is below or above
the level, the contact is in open-circuit posion. In order for a
test execuon to make, apply an external magnet or the mag-
net side of water-gauge located in the devices of Level Indica-
tor of MLG Series into the body of PS1x/PS3x Limit Switch in
the manner almost to touch it; A short circuit (a resistance
value near zero) must be read in Ω posion of the measuring
instrument. If the open circuit is read, the PS1x / PS3x Limit
Switches may be defecve. You can proceed to the arcle 5.3.

5.2.2 Determinaon of LS20 Level Control Equipments De-
fects
LS20 Level Controllers also have a NO (Normally Open) con-
tact structure, such as PS1x and PS3x Series Limit Switches.
Tesng of the contacts is the control of switching the contacts
to the closed posion by moving the oat on the LS20 Level
Controller. When measurement is taken in Ω posion of the
measuring instrument, short circuit (near zero resistance val-
ue) must be read out by bringing the oat over the set contact
points in the factory.
More than one contact can be observed at a distance of 2-3
cm for the same contact. This situaon is related to contact
sensivity and this does not deem to indicate a failure.
LS20 Level Controllers do not have a standard test procedure
as they are custom built specic to the applicaon. for appli-
caon specic producon. The test should be performed tak-
ing the connecon diagram of the product into consideraon.
In case that these measurement values are not obtained, pro-
ceed to the arcle 5.3.
