3.0 Adjustment, operational elements and functional displays
3.1 With the digital potentiometer "Anzeige", all values and settings can be checked. If a setting needs
to be adjusted, the potentiometer has to be turned until the display shows the desired setting. Now
the button "Auswahl/Quittung"needs to be pressed. The value saved last will start to flash. Settings
may be changed by the potentiometer. Turning fast will cause greater changes of the values,
turning slowly allows for precise adjustments. Once the desired value is attained, it needs to be
confirmed with the button "Auswahl/ Quittung". The value stops flashing and is saved. All values
need to be checked once before the initial start-up. After 20 seconds, the display automatically
switches back to the initial setting.
The hours of operation are accounted for continuously. Changing or
resetting them is not possible.
3.2 Operational elements

4.2 Additions to individual bullets of the settings menu
Adjustment of control settings
Start Delay
The pre-set start delay will only be active after a power outage. For all further activations the pumps
will start up right away once activated by the level.
Minimal level settings (On/Off)
If the start level is chosen to be smaller than 5 cm, the software will automatically use 5 cm as start
level. If a stop level is chosen to be smaller than 3 cm, the software will automatically use 3 cm as
stop level.. In addition, the start of the stop delay time will then begin at 3 cm. This is necessary in
order to safely operate the control unit.
Stop delay
Stop delay will make it possible to pump out below the level sensor (for example for impact
pressure systems)
NEW ! Monitoring of operating time
The bullet “Operation limit” can be chosen in the menu. In the condition supplied at delivery, the
value is set to zero. This means the function is deactivated. If the value is set between 1 – 60
minutes the pump will be deactivated once it ran for longer than the pre-set time without
interruption. Additionally, an alarm will be triggered and an according fault report will appear on the
display. The pump will only proceed once the fault has been confirmed. The operation time
monitoring concerns the automatic mode and the manual mode.
Current limit (max. current)
The nominal current of the according pumps can be adjusted directly. The software of the control
unit will add a certain percentage to a set value in order to adjust tolerances.The activation will occur
according to a I² / t function and therefore considers the high starting current of the pump.For
pumps where the temperature control consists of a single bimetallic contact, the malfunction
“thermal fault 1” can be deactivated in the menu. “Thermal fault 2” cannot be deactivated in the
menu.

PS 1 – LCD
www.lesa.de – the fastest way to get in touch!10
NEW! Fault memory
The last 4 errors that occurred remain safe even with no power and can be called up in the menu
under "Last fault".
Caution Last fault 1 is the last fault the occurred. If the last fault 1 is called up in the menu, the last
fault can be deleted from the memory with the acknowledgement button.
NEW! Rotating field fault
The rotating field monitor monitors the phase sequence as well as the absence of a phase. In case
of a phase malfunction the pumps are locked, an alarm is triggered, and the display shows the
message “Rotating field fault”. The rotating field monitor can be activated and deactivated in the
menu. When operating single phase motors the rotating field monitor has to be deactivated.
Atex – Mode
For application of pumps in the Ex – area the Atex- mode needs to be activated in the menu. The
Atex-mode prevents an activation of the pump through the manual mode, the forced activation, or
the remote control system as long as the stop level has not been reached. If the pumps are
activated over the stop delay mode or manual mode while the stop level is exceeded, it is possible to
pump out in order to reach a level below the stop level. After 2 minutes, the manual mode is
automatically deactivated. If the Atex-mode prevents the pump from being activated, the display
will show the message “ATEX: Level less than stop level”.
Service – Mode
ATTENTION! In the condition supplied at delivery the service mode is activated, meaning all
settings can be adjusted. Deactivating the service mode in the menu leads to only being able to
check values over the digital potentiometer. While the service mode is deactivated no setting (with
the exception of “language”) can be adjusted.
Level Control
There is a choice whether the control unit is operated by the internal level sensor (impact pressure,
air supply), an external level sensor 4-20 mA, or a floating switch.
ATTENTION! The terminal for the high-water alarm (terminal 16/17) always remains active and may
be used as a redundant monitor. As soon as terminals 16/17 are connected, high-water alarm will be
triggered and the pump is activated.
When utilizing external 4-20 mA level sensors and floating switches that are mounted in the Ex-
area, components with according approvals need to be used as well.
20 mA =>Level
This setting causes the control settings and the level display to be aligned with a connected external
4-20 mA level sensor. The processor re-calculates the incoming signal so the correct level is
displayed.
ATTENTION! If the effective range of the 4-20 mA level sensor has been changed in the menu, the
level settings need to be re-adjusted as well because they will have changed with the system.
Therefore, the right order would be to first change the effective range of the Level sensor and to
adjust the level settings afterwards. For operation in the Ex-zone according regulations have to be
obeyed. This means the 4-20 mA level sensor needs to have the according approval and a matching
Ex-barrier needs to be used.If the control settings lie outside the set range of the level sensor, the
message “Please check control settings” will be displayed.

6.0 Installation, electrical connection
6.1 Installation
The control unit PS1 – LCD N is placed in a control box that measures 290 x 170 x 130mm (H x W x
D with bolts and air connection). In order to attach the control box, there are 4 drilled holes.
6.2 Hose connection
The delivery standard for the hose connection is a screwed hose connection 8/6 mm. As an option
the control unit can be delivered with different screwed hose connections. It is also possible to
exchange the screwed hose connection later on. The hose connection needs to have an inside
thread G1/8” towards the control unit. When exchanging the hose connection it is important to hold
the according nut with a 14 mm wrench. You need to make sure to use an appropriate sealing agent
when inserting the screw connection.
6.3. Electric connection, power supply, and pumps
The electric connection needs to be installed by an electrician according to the valid regulations.
A circuit protection to the mains of max. 3 x 16 A (delay action) needs to be installed.
Connection Power supply (3 ~) L1, L2, L3, N, PE (pic 1a in attachment)
(There is a duplicate to each terminal and they are bridged internally)
The terminals are designed for a max cable cross sectional area of 4 mm². It is important to make
sure a right-sided rotating field is set-up. The terminals are labeled L1, L2, L3, N and PE.

PS 1 – LCD
www.lesa.de – the fastest way to get in touch!13
Connection of pump:
The connections L1 L2 L3 of the pump are directly attached to the motor contactor. The protective
earth conductor is connected to the remaining PE terminal.
The bimetallic contact, which unlocks the pump after it has cooled down, needs to be connected to
terminal 20/21; the bimetallic contact that unlocks the pump after pressing the “Quittung” button
needs to be connected to terminal 21/22 on the upper circuit board. (In case Temp.1 is not being
connected, thermal fault 1 needs to be deactivated in the menu).
To operate 1 ~ motors (230V AC)a bridge between input terminal L1 to L2, as well as between N
an L3 are necessary.
Power supply to the pumps (1~)
The connection of the pumps occurs on contactor T2 = L und T3 = N
ATTENTION! Because measuring the current needs to happen through T2, the motor needs to be
connected at this terminal.
Thermal motor protection contact
Warning contact Temp 1 / Terminal 20/21
the pump is unlocked automatically after having cooled off.
Limiting contact Temp 2 / Terminal 21/22
The pump is unlocked after pushing the button “Quittung”
If Temp.1 is not used, the mode needs to be deactivated in the menu (compare to 4.2).
If Temp. 2 is not used, a wire jumper needs to be put in place between terminal 21 and 22.
For pumps in which the bimetallic contact is connected in a way so it will directly interrupt the
current of the pump, the message “Pump Off” will appear once the bimetallic contact triggers. The
pump will only resume operation once the fault report is confirmed (Quittung).
