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.

7. Electrical connection for Slave Module/s
The controllers of the ESY-1 / ALL-in-ONE series include moreover the SLAVE-ONE power units, in the two following
versions:
-SLAVE-SV with input for 0-10Vdc control signal
-SLAVE-SP with input for PWM control signal
All the models of the series share the same technical characteristics and are available in different sizes:
8 A – 12 A – 16 A – 20 A, 230Vac/50Hz, all suitable for outdoor applications, in plastic case 120°C and protection degree
IP55.
Moreover, the SLAVE-SV control unit, with control input 0-10Vdc has an auxiliary output that allows to control further
SLAVE-SP units.
By using exclusively SLAVE-SV units, it is possible to share equally the total load on the three-phases (R-S-T), so as to prevent
the risk of overloading the electric line on just one phase (regulation performed by two or more controllers, which have the 0-
10Vdc control signal in common).
The SLAVE-SV modules do not require the same supply phase for every module connected to the 0-10Vdc control signal
(network synchronization), which is instead needed when connecting SLAVE-SP units (PWM input).

9. Set-up of operating LIMITS and PARAMETERS
9.1. Available regulations in the standard ESY-1 version (ALL-in-ONE)
The ESY-1 controllers present two regulation Trimmers for setting up the operating limits (MIN out / Cut-Off and
MAX out), the automatic regulation performs the variations of fans speed, and a couple of 13-positions rotary
switches for setting up the SET-Point of reference with ease.
9.2. How to set up the operating limits for the ALL-in-ONE version
Before starting the set-up procedure for operating parameters, it is necessary to determine the AC voltage operating
limits, within which the automatic variation of speed takes place. The limits must be set up according to the procedures
described as follows:
MAX Vac
limit
It determines the value of maximum AC voltage to be supplied to
the fan in automatic operation (from 100% to 0%), in order to
limit the maximum airflow rate or the fan noise at MAX rpm.
It is factory preset at the maximum value of ‘10’, corresponding
to the 100% of the control value.
Set up of 'MAX out' voltage value:
1) move the Jumper J1 to ON 1(REV) position;
2) turn the trimmer MAX out from position ‘10’ up to the desired value of MAX AC
voltage limit;
3) turn the Jumper J1 back to the ON 2 position
- in automatic operation, the MAX- RPM% limit of output voltage supplied to the
load corresponds to the determined AC voltage limit.
Cut-Off
limit
It determines the value of minimum AC voltage to be supplied to
the fan in automatic operation (from 25% to 80%): the starting
voltage supplied to the fan is enough to give an adequate torque to
start the fan rotation.
Set up of 'CUT-OFF' voltage value:
1) move the Jumper J3 to ON 2 position;
2) turn the trimmer from ’1’ position up to the desired AC voltage value of MIN rpm;
3) turn the Jumper J3 back to the ON 1 position
- the regulation of the fan starts from the determined CUT-Off VAC value
MIN Vac
limit
It allows to set up manually the minimum AC output voltage
supplied to the fan, from 20% to 80%, and permits to check:
- the correct phase-cutting of the controller
- the Cut-OFF set up
Set up of 'MIN out' voltage value:
1) move the Jumper J3 to ON 2 position;
2) turn the trimmer from ’1’ position, until reaching the desired MIN rpm voltage
value
- At start up the fan operates at the determined minimum Ac voltage limit
MAX-out

CUT-OFF

9.3. How to set up the operating limits for SLAVE-ONE modules (only SLAVE-SV version)
The following procedures allow to set up the AC voltage limits, within which the 0-10 Vdc control signal is automatically
controlled.
MIN Vac
limit
It allows to set up manually the minimum AC output voltage
supplied to the fan, from 20% to 90%, and permits to check:
- the correct phase-cutting of the controller
- the Cut-OFF set up
Set up of 'MIN VAC out' voltage value:
1) move the Jumper J3 in ON 1 position;
2) turn the trimmer from ’1’ position, until reaching the desired MIN rpm voltage
value; now the load is always supplied starting from the determined MAX AC
voltage limit
Cut-OFF
limit
It determines the value of minimum AC voltage to be
supplied to the fan in automatic operation (from 25% to
80%): this prevent the fan to be supplied with a lower AC
voltage, which would be not enough to give an adequate
torque for keeping the fan rotating.
Set up of 'CUT-OFF' AC voltage value:
1) move the Jumper J3 to ON 1 position;
2) turn the trimmer from ’1’ position, until reaching the desired MIN rpm
voltage value
3) turn the Jumper J3 back to the ON 2 position
now the load is supplied starting from the CUT-Off value
MAX Vac
limit
It determines the value of maximum AC voltage to be
supplied to the fan in automatic operation (from 100% to
20%), in order to limit the maximum airflow rate or the fan
noise at MAX rpm.
It is factory preset at the maximum value of ‘10’,
corresponding to the 100% of the control value.
Set up of 'MAX out' voltage value:
1) jumper the inputs IN and +10V: the AC voltage output is at 100%
2) turn the trimmer MAX out from position ‘10’ up to the desired value of MAX
AC voltage limit (ex.: 80%);
3) remove the jumper between IN and +10V : in automatic operation, the MAX
voltage limit supplied to the load corresponds to the determined AC output
voltage limit
9.4. Table showing the scale of values for setting up the ESY-1 regulation VAC Limits

After selecting the operating modes and setting up the operating limits, it is necessary to determine the operating point of
the regulation: the SET-POINT, on the basis of the scales and ranges referring to the connected sensor (*).
The Set-Point is easily and quickly fixed through the couple of 13-position rotary switches, named as follows: SP
(main reference point for the regulation) and SPadj. (accurate adjustment of the operating point fixed with SP).
For the selection of the Set-Point values, refer to the following tables according to the ranges and to the types of sensors
in use.
(*) The controller ESY-1 operates automatically according to the sensor/signal currently connected or in use.
