1. INTRODUCTION

This manual must always accompany the relevant equipment and be conserved in an accessible
location for consultation by qualified technicians assigned for operation and maintenance of the
system.

The installer/user is strongly recommended to carefully read all instructions and information in this
manual before using the product, in order to avoid damage or improper use of the unit, which
would also render the warranty null and void.

Before operating the equipment, carefully read the manual and follow all instructions provided.

The information and instructions in this manual refer to the standard use of this product; in the
event of special circumstances, functions or applications not described in this document, contact our
service center for assistance.

If technical assistance or spare parts are required, when contacting the manufacturer always specify
the identification code of the model and construction number as stated on the data plate.

Our service center is available for any requirement or clarification.

On receipt of the goods, inspect immediately to ensure that the equipment has not been damaged
during transport. If defects are found, the client should promptly notify our retailer within 5 days of
receiving the goods, or in the event of direct purchases, the Elentek service center.

N.B. the information provided in this manual is subject to modifications without
notice. The manufacturer shall not be held liable for any damage caused in relation
to the use of these instructions, as they are to be considered guideline only. Note
that failure to observe the instructions provided in this manual may cause physical
injury or damage to objects.

In any event all local and/or current legislation must be observed at all times.

2. WARNINGS

The electrical panel must be used exclusively for the purpose and function as specified in design.
Any other application or use is to be considered improper and therefore hazardous.

In the event of a fire in the place of installation or the surrounding area, avoid the use of water jets
and use the appropriate extinguishing equipment and means (powder, foam, carbon dioxide).

Install the equipment far from heat sources and in a dry and sheltered location in observance of the
stated protection rating (IP).

The installation of a safety device is recommended to protect the panel power line in compliance
with current electrical standards.

The electrical panel must be connected by a qualified electrician in observance of the relevant
electrical standards.

No parts of the panel must be disassembled without the official authorization of Elentek: any
tampering with or modifications to the unit will render all terms of the warranty null and void.

All installation and/or maintenance operations must be performed by a specialized technician who is
fully aware of the relevant current safety standards.

Ensure the installation is connected to an efficient earthing system.

After making the electrical connection, check that all electrical panel settings are correct to avoid
automatic start-up of the electric pump.

Elentek declines all liability in the event of the following:

- Incorrect installation;

- Use by personnel not adequately trained in the correct use of the panel;

- Serious failure to perform scheduled maintenance;

- Use of non-original spare parts or parts not specific to the model;

- Unauthorized modifications or interventions;

- Partial or total failure to observe instructions.

7

3. INSTALLATION

Ensure that the mains power supply specifications correspond to the voltage specified on the data
plate of the electrical panel and motor connected, then make the earthing connection before all
other connections.

The power line must be protected by a residual current circuit breaker.

Tighten the electrical cables on the relative terminals using a suitable tool correctly sized to avoid
the risk of damage to the fixing screws. Take care if using an electric screwdriver.

The electrical panel is designed for wall-mounting using screws and plugs in the pre-drilled holes at
the corners of the enclosure, or by means of brackets when present.

Install the equipment in areas compliant with the protection rating and ensure that the box is kept
intact when drilling the holes for fitting the cable clamps.

Avoid the use of multicore cables where there are wires connected to inductive loads and power
cables and signal cables such as sensors and digital inputs.

Keep connection cables as short as possible, preventing any twisting of cables, which may be
harmful due to inductive effects on the electronic equipment.

All wires used in the cabling must be suitably sized to withstand the load to be powered.

On activation of the panel, the display shows the following:

At the end of the start-up sequence, the main menu is displayed, as described below.

MAIN SCREEN: This screen enables the display of active motors, voltage on
input and total absorption of the panel:

 230 V = Power supply voltage reading;
 7.0 Atot = Total current absorbed by the panel;
 P1 ( 0 ) = Motor 1 deactivated; P1 ( 1 ) = Motor 1 active;
 P2 ( 0 ) = Motor 2 deactivated; P2 ( 1 ) = Motor 2 active;
 P3 ( 0 ) = Motor 3 deactivated; P3 ( 1 ) = Motor 3 active;

If operating modes are used with analogue signals, the main screen also

displays the input signal expressed as a percentage, in metres or bar.

MOTOR SCREEN: By pressing SETUP the user can view the screen of each
motor (P1, P2 and P3), where the following is displayed:

 230 V = Power supply voltage reading;
 0.0 A = Current absorbed by connected load;
 1.0 ϕ = Power factor of connected load;
 MAN () = Panel set to manual mode;

4.2 Activation of load in manual mode

On start-up, the panel starts in automatic mode, as confirmed by the asterisk () displayed
alongside the text AUT on the display of each motor, or according to the previous status set before
shutdown.

The operating mode can be changed by pressing the UP arrow to change to Manual mode, or the
DOWN arrow to change to Automatic mode.

Therefore, to enable operation in Manual mode, press the UP arrow (the asterisk () is displayed
alongside the text MAN) and then press and hold OK.

The display then displays current absorption of the motor and the cos-phi power factor values in real
time.

On release of the OK button, the motor is shut down.

N.B. in manual mode, the load is activated and bypasses all alarms, but in the event
of a faulty the display flashes.
