1.1 Product description
LORENTZ PS DataModule
The LORENTZ PS DataModule is an integral data logger and remote control device
for the whole PS and PSk2 range of helical, centrifugal and surface pumps. The PS
DataModule is pre-installed in PS Controllers and embedded in PS2 and PSk2 Con-
trollers with Smart Solution support. The PS DataModule measures the key data from
the pump system and stores it in on-board memory. Depending on the sample rate
up to 10 years of data can be stored.
LORENTZ PumpScanner
To view real-time data or to collect historic data from the PS DataModule an applica-
tion called “PumpScanner” is used. PumpScanner runs on the Android Operating
System (smartphone or tablet) and communicates with the PS DataModule via Blue-
tooth. The communication distance is up to 10 m (33 ft). Pump setting changes such
as on/off timers and speed control can also be made.
LORENTZ PS Communicator 3G
The communicator is used to control and read the values and stored data of a pump
system (equipped with a LORENTZ DataModule) via remote control comfortably
from home, office or on the road. It is possible to handle several pump systems.

2 Storage and Handling
On receipt of your product check that the packaging is undamaged and complete. If
any abnormity is found, contact your distributor. The LORENTZ PS Communicator
3G is supplied from the factory in proper packing. It should remain in the packaging
until it is to be installed. Handle the PS Communicator 3G with care and avoid un-
necessary impacts and shocks. The required battery and PV module must be
ordered separately.
Prolonged intermediate storage in an environment of high humidity and fluctuating
temperatures must be avoided. Moisture condensation may damage electrical and
metal parts. Non-compliance will void any warranty. It is recommended to store the
parts in a closed and dry room. The PS Communicator 3G can be stored in the range
of -4 °F to 122 °F (–20 °C to 50 °C). The PS Communicator should not be exposed
to direct sunlight.

4 Installation
The installation should be done with great care and diligence. Before starting, re-
move the bottom lid (with cable glands and 2G / 3G antenna) and pull out the
baseplate carefully. Close the bottom lid, when all work has been done. It is not nec-
essary to open the upper lid of the PS Communicator 3G.
WARNING: Never connect any other power source to the "SOLAR IN" terminal than
the PV module that is specified below. The PS Communicator will periodically short-
circuit the input to measure the irradiation. Any other power source would conse-
quently damage the device and/or the power source itself.
Note: If an external power supply must be used, do not connect the PV module.
Connect a 12V DC power supply to the battery input instead of the battery. Irradiation
measurement will not be possible in this configuration.
4.1 Power supply
The PS Communicator 3G gains its grid independent power from a battery charged
by a PV-module. The required battery and PV module must be ordered sepa-
rately.

The wiring must be done by quali-
fied staff only. The kit includes two
green plugs, one is for the battery
and already pre assembled with a
red (plus) and black (minus) cable.
The second plug is for Solar In.
The two plugs must be removed
from the board before wiring. The
socket on the left lower edge of the
board is for the PV-Module cables
(labeled with “ SOLAR IN”). The
socket on the right lower side of
the board is for the battery cables
(labeled with “BATTERY”).
4.2.1 Battery
Use the 2 pin battery plug with the pre-assembled cables. The red cable is for plus
(+), the black cable is for minus (-).
Make sure the cables are securely mounted to the battery. Ensure and check the
correct polarity.
Remove the battery fixing screw. Slide in the battery. Ensure the battery is correctly
seated and secure it with the battery fixing screw.
Figure 2: Battery fixing
4.2.2 PV-Module
The PV-module has a pre-wired cable. The numbering of the phases is printed on
the cable jacket of the phases (1is for plus (+), 2is for minus (-) ). Thread the cable
through the left cable-gland in the bottom lid. Use the rubber seal (from the plug in
the cable-gland) to seal the cable entry. Connect the cable to the Solar in Terminal.
The left termnial is for plus, the terminal to the right is for minus. Use the cable-gland
in the bottom lid for strain relieve and sealing.
Do not connect the plug at this point. The PS Communicator 3G start-up is described
in chapter 5.
4.2.3 Fuse
The fuse will blow in the event of a battery voltage reversal. The fuse is switched in
the red cable (plus) of the battery cable. Pull out and replace the fuse if it is broken.
The fuse has no special orientation.

4.3 Assembly of PV-Module bracket
We recommend that you use the delivered PV-Module bracket and to install it as
mentioned in this section.
Assemble the brackets to the pre-assembled PV-module braces. Use four M6x16
screws (with 1x washer and 1x spring washer) as shown in Error! Reference s
ource not found.. Fasten the screws with 10Nm.
Figure 3: Mounting of the brackets
4.4 Placement of the PS Communicator 3G
The Communicator must be placed near to the pump controller. The maximum Blue-
tooth range is up to 10m but depends on the surrounding conditions. For example;
walls, shelters or other signals may weaken the signal strength. Keep the PV-Module
free of shadow and with a South (Northern Hemisphere) or North (Southern Hemi-
sphere) orientation. The PV-Module must be kept clean from dirt and snow.
It is recommended to complete the wiring, SIM card installation, battery installation
and an established pump connection before finally mounting the PS Communicator
3G to a wall. See the Start-up section on next page.
To mount the PS Communicator 3G to a wall look at the hole-template below (Figure
4). You just need four of the eight shown holes (for the PS Communicator 3G);
EITHER the four outer holes OR the four inner holes.
Figure 4: Bore template for wall mounting
Fix the PS Communicator 3G with screws on top (see Figure 5).
Two more screws can be used if needed. In that case use the holes in the bottom
lid of the communicator.
Place the PV-Module holder at least 10cm (3.95 in) above the PS Communicator
3G. The holes in the wall, for the PV-Module holder, have to be 330mm (13.0 in)
away from each other. Use M8 screws.

5 Start-up and operation
This chapter describes the start-up of the PS Communicator.
1. Verify that all pump controllers are installed and have PS DataModules
installed.
2. Ensure that every DataModule has been connected to and configured by
the PumpScanner, before the PS Communicator 3G links to them.
Note : If you cannot configure the pump system via PumpScanner
(no pairing PIN) the system can be configured via pumpMANAGER
after connection.
3. Make sure that the pumpMANAGER service subscription (which includes
SIM card activation) has been done on partnerNET.
4. Ensure all pumps within Bluetooth range have power connected to them.
If you are using PumpScanner on any Android device, disconnect it from
the pump before powering the communicator.
5. Connect the power plugs (green plugs inside the PS Communicator 3G).
6. The device will start-up by itself. It starts initialization and searching for
pumps in range (via bluetooth). It then subsequently trys connecting to a
telecommunication network (via 2G/3G) and the LORENTZ pumpMAN-
AGER server. To restart the device and reset the pump pairing , simply
disconnect the power plug for one second and reconnect it.
7. The normal PS communicator 3G LED status is:
•SYSTEM LED is flashing green every 5 seconds
•DISTANT COMMUNICATION LED is flashing yellow every 5
seconds
•LOCAL COMMUNICATION LED is flashing X times (see
Table 2 and example below) every 5 seconds blue
They all start flashing at the same time.
8. When the PS Communicator 3G is connected to the LORENTZ server
and all pumps are connected, slide in the baseplate and close the bottom
lid. Take care to not jam any cables between the housing and the bottom
lid. Ensure the cable glands are tight.
9. If you have not already done so mount the PS communicator 3G to the
wall.
The PS Communicator 3G has an LED bar with 3 LEDs to display the status:
1. SYSTEM green or red
2. DISTANT COMMUNICATION yellow
3. LOCAL COMMUNICATION blue
The table below describes the light sequence of the PS Communicator 3G LED
bar. If any abnormity occurs check the LED status below, especially the “SYS-
TEM”-LED (red).

6 Trouble shooting
6.1 Missing pump connection
If a pump controller does not connect to the PS Communicator 3G check that:
- The pump system has a DataModule installed. PS Controllers that are
equipped with a DataModule have 2 serial numbers on the casing, one
for the Controller and one for the DataModule
- A green system light is shown on the pump controller
- there is no active PumpScanner connection to the pump system
- there are not more than 8 PS Controllers within range of the PS Com-
municator 3G. In this situation the 9th pump would not connect.
- the BlueTooth signal strength is not being impaired by obstacles, walls
or other interfering signals or mounting the PS Communicator 3G in a
metal box.
6.2 No connection to telecommunication network
If the PS Communicator 3G does not connect to the telecommunication (2G/3G)
network check that:
- the SIM card is well seated
- You are using the SIM card supplied by LORENTZ, the PS Communi-
cator 3G will not work with any other SIM cards
- the antenna cable is screwed tightly to the 2G/3G terminal
- there is a mobile phone signal at the site
NOTE: You could use your smartphone to roughly ascertain the
signal strength at the installation site.
-
➢if the circumstances require, test the PS Communicator 3G In an
area with a known good signal (within 1km of a radio mast)
- the PS Communicator 3G is not installed in a location where the signal
will be impaired. Signal strength will be reduced by walls, metal objects,
obstacles, being too distant from each other, interfering signal, etc.)
➢if the circumstances require, test the PS Communicator 3G in an
open area directed to the radio mast
- the antenna cable is not broken
The PS communicator 3G will try to find a network until it is connected. If it does
not find a network there is the risk of emtying the battery.
6.3 No connection to LORENTZ server
If the PS Communicator 3G is not able to establish a connection to the LORENTZ
server contact your distributor for further information.
6.4 Low Voltage Disconnect
The Low Voltage Disconnect (LVD) activates if the battery`s voltage drops below
11.8 volts. The LVD is a protective feature to safe the battery from deep discharge.
The SYSTEM LED flashes red. During LVD there is no Bluetooth or 2G / 3G con-
nection possible.
The PS Communicator 3G returns to normal mode after the battery recovers to 12.2
volts. The voltage is checked once per minute.
6.5 Overheat Safety Shutdown
The Overheat Safety Shutdown is to protect the electronic devices from overheating.
It activates if the temperature in the PS Communicator 3G exceeds 95°C (203°F).
The SYSTEM LED flashes red. During the overheat shutdown there is no Bluetooth
or 2G/3G connection possible.
The PS Communicator 3G returns to normal mode when the temperature has fallen
below 90°C (194°F). The temperature is checked once per minute.
6.6 SIM card
To insert the SIM card into the 2G/3G terminal make sure that the SIM card's con-
tacts are facing left and that the cut-off corner is pointing upwards as the illustration
(Figure 6) shows.
The SIM card must “click” in and should be flush with the outer case (of the 2G / 3G
Terminal). Use a pen or small screw driver to gently push it in (not much pressure
needed).
To remove the SIM card push the card in slightly to release the lock and the card will
be pop out automatically. You can remove now the SIM card. Do not pull the card
while it is locked in the 2G / 3G terminal.
