2.3 Controller Input Wiring
WARNING TEST THE VOLTAGE before
connecting power to the controller.
Voltage (open circuit) must not exceed
150V for PS600 Controller. (Even in cloudy
weather, the open circuit voltage will be
near maximum.)
WARNING Do not apply a direct connection or an amp meter between + and –
when the controller is connected. A short
circuit here will cause a strong discharge.
WARNING SOLAR-DIRECT systems only —
Do not connect any electrical load to the
solar array if it is not part of the LORENTZ
Pump system. Connection of a battery
charger, active solar tracker controller, electric
fence charger, or other load simultaneously
with LORENTZ PS systems may “confuse”
the controller and prevent proper operation.

2. 2 Mechanical Installation
Position If it is outdoors, mount the controller in a
vertical position to assure that rain will not enter the
box.
Battery system Place the controller near the
batteries but safely isolated from the battery terminals and from corrosive gases. (Batteries must be in
a cool location for best longevity and enclosed for
cleanliness and safety.) Connect the battery directly
with the + and – Terminal of the controller. Do not
use the load terminals of the charge controller as
they maybe not strong enough to allow the start
current to flow. The PS600 Controller has a low
voltage function to protect the batteries from deep
discharge. The charger ( additional) is only needed
for charging the batteries.

turn counter-clockwise
2.4 Electrical Installation-Terminals
Power IN For PV-direct systems, a two-pole discon-
nect switch may be installed between the solar array
and the controller. Switch it off to prevent shock and arc
burn hazard during installation and maintenance, or if
the system will be shut down for the season. For Battery
systems: Connect the controller directly to the plus and
minus terminals of the Battery. Do not connect to the
load terminals of the charger as they may be not strong
enough to provide the starting current. A 20 Amp slow
blow fuse must be installed between. The controller and
the battery.
Ground Connect the ground wire to the ground
connection in the controller. Grounding helps to prevent
shock hazard if there is a fault in the motor.
L1 – L2 – L3 ECDRIVE
®
requires four-conductor (fourwire) cable between the controller and the motor. The
three wires L1, L2 and L3 carry power. The fourth wire
carries ground. To reverse direction of rotation reverse
any two wires.
No. 1 and 2 In order to protect the pump from being
damaged by dry running connect one well probe cable
to each terminal. If dry run protection is not needed,
short cut these two terminals.
No. 3, 4 and 5 Connect any kind of external switch
(NO or NC type) for remote control of the controller. In
case no switch is used the terminals No. 4 and 5 have
to be connected with a short cable (factory setting). In
case a NO-switch is used (connected to the terminals
No. 3 and 4) the short cable (connecting the terminals
No. 4 and 5) must remain installed.
No. 6 and 7 Connect these two terminals to switch the
controller to battery mode. The motor will be switched
OFF by the controller if the input voltage is below 11 V
for a 12 V battery system and 22 V for a 24V battery
system in order to protect the battery. If the battery
voltage increases to 13 or 26 V the motor will be
switched ON automatically.
PS600 pump systems can be operated from batteries.
Short Circuit protection Install a fuse or circuit breaker
near the power source. For either 48V , use a 20 amp
circuit breaker or a time-delay (slow blow) fuse. The
purpose of this protection is for safety in case of a wiring
fault, and to provide a means of disconnect when installing or maintaining the system. PS600 controllers have
electronic over-current protection against motor overload.
Low-voltage disconnect function. Lead-acid batteries
can be permanently damaged by over-discharge when
the voltage falls below a critical point. To prevent this, the
PS battery-system controller will turn off at low voltage,
and turn back on only after the battery has recovered
significantly. The set points are:
48V SYSTEM: OFF at 44V ON at 48V
A controller in disconnect mode can be reset manually by
turning off/on, but it will quickly disconnect again if the
battery is not gaining a substantial recharge.
2.5 Battery-Based Systems
Wire Sizing for the DC circuit Wire must be sized for
no more than 5% voltage drop at 20 amps (starting).
Refer to a wire sizing chart for 48V, or follow these
examples:
Solar Direct Systems
#10 wire to maximum distance of 30 ft.
Metric: 4 sq. mm to max. 20m
Battery Systems:
#10 wire to maximum distance of 30 ft.
Metric: 4 sq. mm to max. 15m
GREATER LENGTHS For each 150% increase, use
next larger wire size

3 OPERATING THE PUMP
This explains the function of the switch and
the indicator lights on the pump controller.
SWITCH
POWER ON/OFF
When switched off/on during operation, it resets all
system logic.
Indicator lights
SYSTEM (green)
The controller is switched on and the power source
is present. In low-power conditions, the light may
show even if there is not enough power to run the
pump.
PUMP ON (green)
Motor is turning. Sequence of flashing indicates
pump speed. See below sequence
PUMP OVERLOAD (green changes to red)
SOURCE LOW (red)
The water source dropped below the level of the lowwater probe. After the water level recovers, the pump
will restart, but this light will slowly flash until the sun
goes down, power is interrupted, or the POWER
switch is reset. This indicates that the water source
ran low at least once since the previous off/on cycle.
TANK FULL (red)
Pump is turned off by action of the remote float
switch (or pressure switch or manual switch,
whichever is wired to the “remote float switch”
terminals.
BATTERY LOW (tank light flashes)
Battery systems only – battery voltage fell to 44V,
and has not yet recovered to 48V.
RPM indication: Pump speed can be read off by
the flashing sequence of the Pump ON LED.
LED ON > 900
One flash > 1200
Two flash > 1600
Three flash > 2000
Four flash > 2400
Five flash > 2800

Starting the pump Be sure there is not a
closed valve or other obstruction in the water
line.
Fill the pump with clean water until the water
level reaches the inlet connection. Coat the
O-Ring seal with Vaseline, close the lid by
hand and make sure that it is well in the
housing groove. Otherwise the pump will
prime insufficiently or not at all.
NEVER LET THE PUMP RUN DRY, NOT
EVEN FOR THE PURPOSE OF CHECKING
THE DIRECTION OF ROTATION !
Switch on the array disconnect switch, and
toggle the power switch on the controller. It is
normal to leave the switches on at all times,
unless you desire to have the system off.
A solar-direct pump should start under the
following conditions
1. clear sunshine at an angle of about 20° or
more from the surface of the solar array
2. cloudy conditions, if the sunshine is bright
enough to cast some shadow
3. low-water probe submersed in the water
source (or bypassed in the controller) –
Water-Low light OFF
4. full-tank float switch is not responding to a
full tank – Tank-Full light OFF
5. battery system only – voltage is higher
than the low-voltage disconnect point of
44V.
When sunshine is insufficient When
sunshine on the array is present, but too
weak for the pump to run, it will attempt to
start about every 120 seconds. During each
attempt, you will see the PUMP ON light
come on.
When pump runs slowly (PUMP ON) under
weak sun conditions the pump may spin
without lifting water all the way to the outlet.
This is normal.
When pump stops from a sudden shadow on
the solar array
If a shadow suddenly passes over the array,
like if you walk in front if it, the controller will
lose track of the input voltage. This does
NOT indicate a problem. The pump will
attempt to restart after the normal delay.
Time delays
1. After pump stops due to insufficient
sunshine – 120 SECONDS
2. After full-tank float switch resets – 2 to 3
SECONDS
3. After low-water probe regains contact with
water in the source -– 20 MINUTES but
the indicator light will slowly falsh for the
rest of the solar day, or until power is
disrupted or the controller is turned off/on.
4. Battery systems – after low voltage
disconnect point is reached, delay to stop
pump – a few SECONDS. After voltage
recovers, delay to re-connect – a few
SECONDS
To force a quick start To test or observe the
system, you can bypass the normal time
delays. Switch the POWER switch off then on
again. The pump should start immediately if
sufficient power is present.

4 Automatic Control For Full-Tank Shutoff
We recommend the use of a float switch or
other means to prevent overflow of your tank.
This will stop the pump when the tank is full,
then reset when the level drops. This conserves ground water, prevents overflow, and
eliminates unnecessary pump wear. PS-XXX
controllers allow the use of small signal cable
to a remote float switch, even if the tank is a
long distance away.
Float switch requirements
1. A switch must be used, not wet electrodes.
2. The preferred system requires a float
switch to MAKE contact on rise to turn the
pump OFF. This is called “normally open”
(N.O.). It may be commercially labeled as a
“pump down” switch, but here it works in
reverse, to allow pumping up.

range
Wiring to the controller
The controller offers two
options for connection of a
remote switch. These allow
the use of either a
“normally open” (N.O.) or
a “normally closed” (N.C.)
switch. “Normal” refers to
the status of the contacts
when the switch is DOWN
and calling for water.
Float switch cable requirements
1. Two wires are needed.
2. Minimum wire size #18
AWG ( 1mm²). This is good
for a distance as far as 2000
feet (600 m).
3. The cable must be suitable
for its environment.
4. If it must run a long
distance, use twisted-pair
shielded cable to reduce the
chance of damage from lightning-induced
surge.
Grounding shielded float switch cable If
you use shielded cable, connect the shield to
ground AT THE CONTROLLER ONLY. DO
NOT ground the shield at the float switch.
This will reduce surges induced by nearby
lightning.
Wiring a “normally open switch” Connect the switch to terminals 3 and 4 (NO and
common) and connect terminals 4 and 5 together, as illustrated.
Closing (connecting) the switch circuit turns the pump OFF
Wiring a “normally closed/reverse action switch” Connect the switch to termins 4
and 5. Closing (connecting) the switch turns the pump ON

5 TROUBLE SHOOTING
Please read this section before calling for help.
If you call for help, please refer to the model and serial
numbers. (See SYSTEM REPORT, page 3.)
If The Pump Does Not Run
Most problems are caused by wrong connections (in a
new installation) or failed connections, especially
where a wire is not secure and falls out of a terminal.
The System ON light will indicate that system is
switched on and connected to the controller. It
indicates that VOLTAGE is present but (in a solardirect system) there may not be sufficient power to
start the pump. It should attempt to start at intervals of
120 seconds.
Pump attempts to start every 120 seconds but
doesn’t run
The controller makes a slight noise as it tries to start
the pump. The pump will start to turn or just vibrate a
little.
1. There may be insufficient power reaching the
controller. A solar-direct (non-battery) system
should start if there is enough sun to cast a slight
shadow. A battery system should start if the supply
voltage is greater than 44V.
2. If the pump was recently connected (or reconnected) to the controller, it may be running in
reverse direction due to wiring error.
3. If the motor shaft only vibrates and will not turn, it
may be getting power on only two of the three
motor wires. This will happen if there is a broken
connection or if you accidentally exchanged one of
the power wires with the ground wire.
4. The pump or pipe may be packed with mud, clay,
sand or debris.
PUMP OVERLOAD (PUMP ON light shows red
instead of green) The system has shut off due to an
overload. This can happen if the motor or pump is
blocked or very difficult to turn and is drawing excessive current (hard to turn). Overload detection requires
at least 250 Watt output of the solar array. This can be
caused by a high concentration of solids in the
pump.The controller will make 3 start attempts before
shutting down the system. The System ON LED will be
OFF and the red OVERLOAD LED ON. The system
will not reset until the ON / OFF switch is turned OFF
and ON again. See Troubleshooting, Section 9.3
“HIGHER CURRENT”.
Inspect the solar array
1. Is it facing the sun?
2. Is there a partial shadow on the array? If only 10%
of the array is shadowed, it can stop the pump!
Inspect all wires and connections
1. Look carefully for improper wiring (especially in a new
installation).
2. Make a visual inspection of the condition of the wires and
connections. Wires are often chewed by animals if they are
not enclosed in conduit (pipe).
3. Pull wires with your hands to check for failed connections.
Inspect the controller
1. Remove the screws from the bottom plate of the controller.
Move the plate downward (or the controller upward) to reveal
the terminal block where the wires connect.
2. First, check for a burnt smell. This will indicate a failure of the
electronics. Look for burnt wires, bits of black debris, and any
other signs of lightning damage.
3. Inspect the grounding wires and connections! Most controller
failures are caused by an induced surge from nearby lightning
where the system is NOT effectively grounded. Ground
connections must be properly made and free of corrosion.
Check the low-water probe system
If the controller indicates “SOURCE LOW” when the pump is in
the water, inspect the low-water probe system. The probe is
mounted on, or near the pump. If inspection is not feasible, you
can bypass the probe or test it electrically.
Check the full-tank float switch
If the controller indicates “TANK FULL” when the storage tank is
not full, inspect the float switch system. If your system has a float
switch, it will be mounted in the tank. If inspection is not feasible,
you can bypass the switch or test it electrically.
Force a quick start
If you restore a connection or bypass the probe or float switch,
there is no need to wait for the normal time delay. Switch the on/
off switch (or the power source) off then on again. The pump
should start immediately if sufficient power is present.
If the pump responds to the bypass tests above but not to the
float switch, the wires may be shorted (touching each other) or
open (broken), or the switch may be stuck with debris, or out of its
correct position.
1. Is the solar array receiving shadow-free light? (It only takes a
small shadow to stop it.) Is it oriented properly toward the
south, and tilted at the proper angle?
2. Be sure you have the right pump for the total lift that is
required.
3. Be sure all wire and pipe runs are sized adequately for the
distance. Refer to wire sizing in the pump sizing table.
4. Inspect and test the solar array circuit and the controller
output, as above. Write down your measurements.
5. There may be a leak in the pipe from the pump.
6. There is a “max. RPM” adjustment in the controller. It may
have been set to reduce the flow as low as 30%.

6 MAINTENANCE
Controller and Pump
The controllers electronic has no moving or
wearing parts. It requires no maintenance.
There are rubber plugs to seal at the bottom,
unused conduit holes. Inspect them to insure
that the controller is sealed from moisture,
insects, etc. Check that mounting and conduit
hardware is tight.
Motor The motor requires no maintenance.
It has no brushes or other frequently wearing
parts.
Pump end The pump mechanism (pump
end) is lubricated only by water and requires
no maintenance. It may wear after some
years, especially if there are abrasive solids in
the water. If sand accumulates in the storage
tank or pipes as a result of normal pumping, it
is best to take periodic measurement of the
pump’s performance. A worn pump end can
be replaced in the field.
