SWITCHBOARD USER MANUAL 3
Use of symbols
The symbols used in this manual refer to the following:
WARNING
The following text contains instructions aimed at preventing injury or direct damage to the crops,
the product and/or the infrastructure.
CAUTION
The following text contains instructions aimed at preventing unwanted system operation,
installation or conditions that, if not followed, might void the warranty.
ATTENTION
The following text contains instructions aimed at enhancing the efficiency of usage of the
instructions in the manual.
NOTE
The following text contains instructions aimed at emphasizing certain aspect of the operation of
the system or installation.
ELECTRICAL HAZARD
The following text contains instructions aimed at preventing death or injury by electrocution
or direct damage to the product and/or the infrastructure.
SAFETY FOOTWEAR

Safety instructions
WARNING
In agricultural environment - always wear protective footwear.
DANGER
Hazard of electric shock, explosion, or arc flash. Disconnect all power before servicing equipment.
Failure to follow these instructions will result in death or serious injury.
CAUTION
Only qualified electricians are permitted to perform electrical installations and repairs!
WARNING
The Universal Pump Switchboard does NOT provide protection against electrocution
since it does not include an earth-leakage circuit breaker.
The following items must be provided in the infrastructure:
• A readily accessible circuit breaker, rated according to the total rated power of the load, certified
as branch circuit over current protector compliant with the national code and requirements,
• Grounding connection: ≤ 10 Ω.
• All safety regulations must be applied.
• The electrical installation must comply with the local safety standards and regulations.
• Protection provided by the equipment may be impaired if the equipment is used in a manner other than
that specified by the manufacturer.
IP code: IP54
4 SWITCHBOARD USER MANUAL
DESCRIPTION
Functionality
The Universal Pump Switchboard is designed to activate the pump at a command from the controller,
provided there is sufficient water pressure in the mainline.
If the water pressure in the mainline is too low, a low-pressure signal is transmitted to the controller.
The controller may deactivate the pump.
The pump can be activated/deactivated manually via a manual override.
ATTENTION
If the pump is activated manually via a manual override, low-pressure protection is not active,
since it is also overridden.
It is also possible to disconnect the pump manually.
The Universal Pump Switchboard is equipped with 6 double-level terminals enabling the connection of the
command lines to the solenoides of the dosing channels in addition to the pump command line.
When connecting an external controller, use an 8-wire cable between the switchboard and the controller.
Modularity and flexibility
The switchboard is designed to operate with a large variety of:
Pumps:
• Single-phase pumps (0.5 kW to 2.2 kW)
• Three-phase pumps (0.75 kW to 15 kW)
Mains
• 1 x 100-250V
• 3 x 200-480V
Controllers
• 100-250V connected between phase and neutral
• 100-250V connected between two phases
• 100-250V from an external source
Reliability
• The switchboard is built of high quality components from internationally recognized manufacturers.
• The core of the switchboard is the TELEMECANIQUE's universal breaker TeSys U starter-controller,
also known as "LU".
Easy and accessible maintenance
• The switchboard's straightforward design enables easy and accessible maintenance.
• All its components are available locally in almost any place on the globe.

DESCRIPTION
The TeSys LU
The TeSys U at the heart of the Universal Pump Switchboard
replaces conventional components in a smaller space
• The TeSys U starter-controller incorporates all the conventionally associated functions:
circuit breaker + contactor + thermal relay.
• It considerably reduces wiring time.
• The electircal coordination of the
components is intrisically ensured.
Equivalent to
Advantages
• Space-saving
• Time-saving
• Safety
The TeSys LU is composed of the following modules:
• LUB power base
This power base incorporates the power components: thermal blocks,
switching mechanism and power contacts. It also incorporates the
auxiliary contacts (terminal block not included).
• LUC supervisable control unit
Detection / tripping / measurement.

for the pump.
WARNING
The polarity of the low voltage lines (24 VAC) must be observed - N24 = common from controller.
SWITCHBOARD USER MANUAL 11
ELECTRICAL CIRCUITS
Guidelines for connections
All the commands to the switchboard are 24 VAC
If the Universal Pump Switchboard is supplied factory-installed in a dosing unit, the dosing channels are
already connected.
If the Universal Pump Switchboard is supplied separately, connect the dosing channels as shown in the
Control Diagram, page 11.
COM
When connecting the "Fault to controller" command line, make sure to program in the controller so that
upon receiving a pump deactivation command from the switchboard, the controller deactivates the pump
with a delay of a few seconds (see the Controller Manual).
V
NOTE
When multiple dosing units are operated by a
single controller (as typical of the NMC XL),
the dosing channel solenoides are connected
via a relay, as shown.

TROUBLESHOOTING
Switchboard warning light
• The switchboard warning light is on (whether the dosing booster is running or not).
Action
1)
Check if the pressure on the main line is too low:
If YES, restore the original main line pressure.
2)
Check if the overload protection breaker is ON.
Toggle it OFF and ON again.
If the switchboard warning light is still on or the overload protection breaker trips (turns to OFF) again,
have a qualified electrician check that the dosing booster is in working order (see the Dosing Booster
Manual) and check for irregularities in the mains.
3)
Check if the overload protection setting of the LU is set according to the pump consumption.
If after implementing all the above steps, the malfunction is still not fixed - consult your Netafim representative.
No automatic start of the pump
• Automatic activation of the pump does not function.
Action
1)
Set the selector switch (SM) to MANUAL.
If the pump still does not function, check the fuses (See List of Spare Parts, page 18)
and replace if necessary.
2)
If the pump still does not function, check whether:
a) The main switch (SO) is set to MANUAL.
b) The selector switch (SM) is not set to AUTO.
c) The LU circuit breaker is set to OFF.
d) The cable to the controller is disconnected or defective.
e) The low voltage (24 VAC) from the controller to the switchboard is inversely connected (N to P) if necessary, reverse it .
f) There is a malfunction of the controller (see the Controller Manual).
If after implementing all the above steps the malfunction is still not fixed - consult your Netafim representative.
The controller does not turn on
• The controller does not receive power supply from the mains.
Action
1)
Make sure the jumpers are placed correctly according to the mains and the controller voltage.
(For 3-phase installation see page 13, for 1-phase installation see page 15).
WARNING
A jumper incorrectly connected may damage the controller!
LU malfunction
• If after implementing all the actions regarding any of the malfunctions above, the malfunction is still not fixed,
it is possible that the reason is a malfunction of the LU (for full documentation on the TeSys LU,
see www.schneider-electric.com).
