WARNING ! HIGH LEAKAGE CURRENT First connect to Earth !

DO NOT touch the electrical parts of the circuit when the power supply is connected

under any circumstances

Safety Warnings

•We disclaim all responsibility for accident, loss or damage caused by the use of these appliances. These must be

correctly installed by qualified personnel in conformity with their intended use and, whenever needed, must undergo

correct maintenance which should be carried out while ensuring the safety of people, domestic animals and goods.

•Do NOT

tamper with or disassemble the regulator internal components; doing so will INVALIDATE THE

GUARANTEE and may cause unnecessary damage. The regulator does not contain components that can be repaired

by the user.

•The regulator must be SUITABLY AND EFFECTIVELY EARTHED by the installer, under his own responsibility,

according to the standards in force; earthing is essential for the EMC filter to operate correctly.

Precautions

•When receiving the goods, check that the packing is intact; in the event of any damage due to transportation, notify

the forwarding agent according to legal requirements.

•The regulator must be installed by qualified personnel who will connect the electric supply with GROUND

CONNECTION, attach the cables in their permanent positions and commission the plant.

•Incorrect installation of the ESY100 voltage regulator may cause damage to objects or people, so ensure the

instructions in this manual and all required security measures are read and followed carefully.

•Before supplying power to the unit, make sure that the regulator is correctly connected to the power supply and to

earth. Follow the instructions in this manual exactly and observe all safety measures in force.

•The user must be protected from the electric supply and the motor must be protected from possible overloads in

compliance with the standards in force. DO NOT touch any electrical parts of the circuit when the power supply is

connected under any circumstances.

•If the mains supply is "disturbed", which may be due to other electrical power components causing irregularities in

the supply (power contactors), it is recommended that supplementary SINGLE phase ‘SURGE ARRESTER’ filters

are installed directly on the regulator supply.

•Avoid repeatedly connecting and disconnecting the power supply to the regulator; a constant supply keeps the

regulator at working temperature and eliminates problems caused by condensate inside the protection case.

•Install the regulator out of direct sunlight, in order to protect the case from overheating. The appliance can operate at

environmental temperatures up to 50°C. Do NOT install it where this temperature may exceed, otherwise the

integrity of the regulator will be compromised, since the controller may make the user appliance operate at full load

(100%) with all consequent effects.

•The equipment must be placed vertically, in order to encourage heat dissipation and to ensure sufficient air

circulation in a free space measuring at least 150 mm above and below the regulator. If several regulators are to be

grouped together on a single electric board, please provide forced air circulation with a fan or with a sufficiently

powerful cooling unit.

3. OPERATING MODES AND APPLICATIONS

The ESY1 devices are electronic analog regulators of single-phase AC voltage, which use the phase-cutting principle (Triac) in order

to vary the output active voltage applied to a resistive or inductive load.

When connected to asynchronous high-slip electric motors of fans or pumps, they control their rotational speed in order to maintain the

key parameter within desired values. On this purpose they have been projected and specialized for control applications on Air Cooled

Heat Exchangers, used in Air Conditioning, Refrigerating, Air Handling and Ventilation Systems.

The series is available in the following versions:

- ALL-in-ONE (multi-input), with 4 control inputs, 3 inputs for mA-Vdc-NTC sensors and 1 0-10Vdc control signal, for MASTER-

SLAVE operating modes.

- SLAVE-ONE, with 1 input for 0-10Vdc (Slave-SV) or PWM (Slave-SP) control signals, to be used as single regulation units or as

additional modules in order to share out the overall controlled power, only for SLAVE operating mode.

With the ALL-in-ONE mode, the selection of input signal and operating mode are performed automatically: the controller operates

through the presently active sensor/signal and there is NO need to use any selection or programming hardware device.

The regulator selects the currently ACTIVE control signal, according to the mode preset by the Jumpers.

It is possible to modify the factory settings during the installation procedure of the device, by moving the following JUMPERS:

J1, operating mode: DIRECT - the VAC output increases as the control signal value increases

REVERSE - the VAC output decreases as the control signal value increases

J2, VAC fans at Set Point: VAC/RMP = 100% with SP = MAX, the Set-P corresponds to the fans Max-speed

VAC/RPM = 0% with SP = MIN, the Set-P corresponds to the fans Min-speed

J3, operation of trimmer P2: MIN for the Min. AC voltage limit supplied to the connected motor;

(J1 for SLAVE-SV) Cut-Off for the AC voltage limit of the connected motor;

J4, output for Slave units control: with control signal for SLAVE-SV units, with 0-10Vdc input signal

with control signal for SLAVE-SP units, with PWM input signal

While the Proportional Band (Pb) values are already factory preset (see Table: Operating Parameters), the Set Point values are

determined through a couple of 13-position rotary switches: SP and SPadj., which are intended to be used quickly and easily even by

base users. The selection of the Set Point is immediate, and two LEDs (+ & -) will show the relationship between this desired value

and the signal value perceived through the presen

tly active sensor; the Set Point will be reached when both LEDs will be off.

In addition, there are LEDs indicating the selection of the First or Second Set Point (only for optional card with double Set Point), and

a LED showing the presence of power supply.

With the SLAVE-ONE version, two types of SLAVE units are available: SV (input 0-10Vdc), and SP (input PWM).

All ESY-1 units are equipped with:

–Complete galvanic separation between AC mains supply and control inputs;

–EMC mains filter with Residential, Commercial & Light Industrial limit (conformity with PDS systems), fit to

be used with equipment directly connected to the low voltage mains supply;

–Overvoltage protection on the mains supply;

–Short circuit protection on the connection of the control sensors/signals;

–Protection filters on control inputs

The ESY-1 series is available in the sizes 8A–12A–16A–20A, with single phase supply voltage 230V/50Hz, and it is housed in a

GW–Plast 120°C case with protection degree IP55 and high impact resistance, for out of doors installations (-20T50).

The controller can be used both in Condenser mode (pressure transducer) and in Dry-Cooler mode (temperature probe) without the

need of any further configuration or programming, with two operating SET-Points (selection of Set-Point 1 & 2), beside the Remote-

SLAVE Unit mode, when driven by an external controller generating a 0-10Vdc control signal.

60Hz applications: only with factory calibration

The regulator works correctly also with 60 Hz, but it is necessary to calibrate the output signal to 100% in order to optimize

the regulation and avoid pulse and beat frequencies.

5. ELECTRICAL CONNECTIONS

Connect the controller as shown in the figure below, paying attention to the following points.

5.1. Power Supply Connection (Terminal Block M1)

-Before supplying power to the unit, check carefully the power connection and the efficiency of EARTH

connection.

-Ensure that power conductors and EARTH CABLES have a cross section suitable to the connected load.

-Place a couple of fuses with suitable amperage upstream of the disconnector.

-Do NOT install the device in environments where ambient temperature may exceed the maximum values allowed (Tamb≤50°C).

-Mount the equipment vertically, in order to encourage heat dissipation and to ensure sufficient air circulation in a free space

measuring at least 150 mm above and below the regulator.

-If the mains supply is "disturbed", which may be due to other electrical power components causing irregularities in the supply, it is

recommended to install supplementary SINGLE phase ‘SURGE ARRESTER’ filters directly on the regulator supply.

-Do NOT alter or damage the identification stickers on the equipment.

-NEVER force the rotary switches beyond their mechanical end stops.

-The power cables (power supply and load), must be installed separately from the control cables, keeping the maximum possible

distance between the power and signal conductors.

-Do not mix power cables and signal cables in the same raceway. Where cables must cross one another, ensure they are at an

angle as near to 90° as possible to minimize interference.

WARNING : Use heat resistant cables, able to withstand a temperature rated at 90° or above.

SURGE ARRESTER : electric protection placed between the regulator supply and the earth, meant to protect the device from

transient overvoltage.

WARNING: Do NOT use differential switches with values lower than 100mA

-It is advisable to provide a by-pass switch in order to run the load even in case of disconnector failure (emergency by-pass). When

connecting the by-pass, it is necessary to keep the phase correspondence unaltered.

6. SIGNAL CONNECTIONS for the 4 CONFIGURATIONS (ALL-in-ONE)

After checking carefully all power supply connections, connect the input signal/s and supply the card.

The output voltage varies from zero Vac to 230 Vac, according to the variation of the control signal.

For the connection of the control signal, use an ordinary twisted-pair cable in disturbance-free environments, while in presence

of environmental electromagnetic disturbances use a shielded twisted cable with the screen connected to earth, keeping it as far

away as possible from other power cables.

The function modes, both always available in the present series, can be:

-MASTER with Set-Point, using the inputs In1–In2–In3 (for 4-20mA, 0-5Vdc or NTC probe)

-SLAVE, using the input In4 ( for 0-10V control signal)

The controllers of the ESY-1/ALL-in-ONE series can be set in the following four (4) configurations, described below.
