1. INTRODUCTION AND ASSEMBLY

1.1 humiSonic (UU0*D)

Range of ultrasonic adiabatic humidiﬁ ers for direct humidiﬁ cation in ducts or air handling units. humiSonic is particularly suitable for many applications in which optimisation of room humidity is an essential factor for personal comfort and the quality of goods. The humidiﬁ ers are controlled by an external electrical panel. Depending on the required functions, this can be the “Slave” (ON/OFF, status signal, remote ON/OFF) or “Master” model (user interface and programming).

1.4 Opening the packaging

□ make sure the humidiﬁ er is intact upon delivery and immediately

notify the transporter, in writing, of any damage that may be due to careless or improper transport;

□ move the humidiﬁ er to the site of installation before removing from

the packaging, grasping the neck from underneath;

□ open the cardboard box, remove the protective material and remove

the humidiﬁ er.

1.5 Material supplied

Make sure the following are included:

1. baﬄ e with 2 bolts;

2. user manual.

1.6 Preparing for assembly

Important: avoid installing the humidiﬁ er in the duct in a position

where it may get wet.

• The unit is designed for assembly in compact air-conditioning units, ventilation systems and air ducts.

• To ensure a very short free path, the atomised water needs to be delivered as uniformly as possible along and across the duct or the unit.

• Install the humidiﬁ er in position where it is easily accessible/removable for maintenance or repairs;

• Make an inspection opening on the wall of the ducting;

• To maximise absorption of atomised water in the air ﬂ ow, for air handling units with:

- is centrifugal, remove the deﬂ ector (D),

- is axial or tangential, install the deﬂ ector (D).

AIR

Fig. 1.b

• Place a drain tank underneath the humidiﬁ er to collect any condensate;

this must be at least 0.6 m long and cover the free path. Install a drain line with drain trap: the height of the drain trap must exceed the system static pressure to ensure adequate draining of the tank.

• Air velocity in the duct must be between 1.5 and 3 m/s, so that the

atomised water is rapidly dispersed. In the event of faster air ﬂ ows, the cross-section of the duct must be increased so that the velocity is within the allowed range. The length of the widened section must be at least 0.6 m beyond the humidiﬁ er in the direction of air ﬂ ow, so as to minimise condensation on the walls of the ducting or air handling unit.

Important:

1. Choose the installation position so that the air ﬂ ow disperses the atomised water uniformly;

2. Make sure that the supporting surface is able to support the weight of the unit.

The humidiﬁ er can only be activated (atomised water production) when the air handling unit fan is running. NEVER start atomised water production without air ﬂ ow in the duct: this may damage one or more parts of the appliance.

1.7 Assembly

The appliance must be assembled on a horizontal support. Check correct positioning using a spirit level.

Procedure:

1. Unscrew the screws (A) and remove the right side cover (B);

Fig. 1.d

2. Secure the humidiﬁ er to the horizontal support using the fastening brackets on the right and left sides;

Fig. 1.e

Important:

1. Install the humidiﬁ er in horizontal position, using a spirit level, so

that the level sensor does not give a false reading;

2. Carefully secure the unit so that it does not move during operation.

1.10 Operating principle

The operation of humiSonic humidiﬁ ers is based on the principle of atomisation of demineralised water using ultrasound technology. The humidiﬁ er operating principle can be summarised as follows:

• water ﬁ ll via a ﬁ ll solenoid valve until reaching the required level,

measured by the ﬂ oat;

• if the autotest is enabled (default), the drain solenoid valve opens and

empties the tank (function designed to clean the tank of any residues/ dirt);

• water ﬁ lled again to the required level;

• start ultrasonic atomisation (the air ﬂ ow in the duct carries the particles

of moisture and distributes them into the surrounding environment);

• water reﬁ ll based on the ﬂ oat measures that the level has fallen below

the recommended value. Ultrasound technology uses a voltage input signal that is transformed via an oscillating circuit into a high frequency signal (1.7 MHz). This signal supplies a transducer, the top of which is in contact with the water, which starts vibrating at high frequency. The surface of the transducer vibrates at very high speed (1.7 million times a second), a speed that does not allow the water to move, due to its inertial mass. Consequently, a column of water is created above the transducer. During the negative amplitude of the transducer cycle, a void is created that is not ﬁ lled by the water (as this cannot respond to the extremely fast movements of the transducer). The cavity thus created leads to the production of bubbles that are pushed to the edge of the water column during the positive amplitude of the cycle, thus colliding. During this process, very ﬁ ne particles of water are atomised on the edge of the water column. The resulting intersecting sound waves created directly underneath the surface of the water cause very small droplets of water to separate, forming a ﬁ ne mist of vapour that is immediately absorbed by the ﬂ ow of air.

2. WATER CONNECTIONS

IMPORTANT: before proceeding with the water connections, make sure that the humidiﬁ er is not connected to the mains power supply.

2.1 Warnings

1. Only use demineralised water. Install a shut-oﬀ valve for each humidiﬁ er.

Allowable water pressure: from 1 to 6 bars;

2. The connections between the pipes/hoses in contact with demineralised

water and the humidiﬁ er must be made from resistant material suitable for this use (e.g. PVC or stainless steel);

3. The water lines must not be fouled by dust particles or other substances.

Carefully clean the lines before connecting to the humidiﬁ er;

4. All humiSonic ultrasonic humidiﬁ ers are supplied with quick couplings

for connecting the ﬁ ll hose (OD / ID = 8/6 mm).

2.2 Water connections (parts not included)

• Install a manual shut-oﬀ valve upstream of the installation (so as to

shut oﬀ the water supply); the valve must be suitable for use with demineralised water.

• Install a mechanical ﬁ lter (10 m) downstream of the manual shut-oﬀ

valve to trap any solid impurities; the ﬁ lter must be ﬁ tted with shut-oﬀ devices to allow cleaning;

• Install a condensate collection basin that is at least 0.6 m longer than

the humidiﬁ er, made from corrosion-resistant material such as plastic or stainless steel.

Important:

1. when installation is completed, ﬂ ush the supply hose for around 30

minutes by piping water directly into the drain, without sending it into the humidiﬁ er. After installing the valve, ﬂ ush with water to eliminate any processing residues and oil and prevent that enter the humidiﬁ er;

2. the drain hose must have a minimum diameter of 6 mm; it must

not have any bends that block water ﬂ ow; the drain line must comply with national and local standards in force and must include a funnel to ensure interruption of continuity and a drain trap to prevent the return of bad odours. The end of the line must have a downwards slope to assist drainage;

3. do not block the atomised water outlet or the intake air

openings;

4. always check for water leaks. If the humidiﬁ er is sprayed with water

during operation, short circuits may occur;

5. if there is the risk of the feedwater freezing, insulate the

water pipes.

2.3 Positioning

As seen in chap.1, the humidiﬁ er must be installed in ducting where the air velocity is between 1.5 and 3 m/s.

Note: when calculating air velocity in the duct, keep in mind that the area occupied by the humidiﬁ er needs to be subtracted from the crosssection of the duct.

The recommended position is downstream of the heating coil.

If assembling multiple humidiﬁ ers, arrange them in a structure that can support the weight of the appliances and that leaves optimum space between the units, so as to ensure eﬃ cient operation. Install a manual shut-oﬀ valve for each humidiﬁ er.

Note: any obstacles in front to the humidiﬁ er are places where water may condense.

2.4 Water connections

Once the humidiﬁ er has been ﬁ tted, make the water connections as follows:

1. Unscrew the screws (A) and remove the right side cover (B);

2.5 Feedwater

To ensure correct operation, humiSonic requires the use of demineralised water, with the chemical and physical characteristics speciﬁ ed in the table. To ensure these water quality values, a reverse-osmosis demineralisation system is typically used.

To avoid excessive oversizing of the reverse osmosis system, it is recommended to avoid sizing the system based on instant ﬂ ow-rate. Rather, an expansion vessel should be installed between the water treatment system and humiSonic.

The sizing calculations need to consider discontinuous water consumption, comprising the following stages:

• ﬁ lling (ﬁ ll valve open);

• production (ﬁ ll valve closed);

• washing (ﬁ ll valve open).

The table below suggests the minimum sizes for connection to a generic reverse osmosis system.

Tab. 0.a

If no storage vessel is available, the reverse osmosis system must guarantee the instant ﬂ ow-rate of the ﬁ ll SV, equal to 2 l/min.

Connecting humiSonic to the Carel WTS Compact

The Carel product range includes a series of reverse osmosis systems (“WTS Compact”) designed to produce water according to the feedwater speciﬁ cations and optimise connection to and operation with humiSonic (see manuals +0300017 and +0300019). All WTS Compact systems (P/N ROC%) always come with an expansion vessel that maintains the required pressure in the circuit downstream. Operation of the system is managed by pressure switches in the outlet circuit. The basic rule for connection to the humidiﬁ er is that the water contained in the expansion vessel must be suﬃ cient to satisfy initial ﬁ lling and, if necessary, the washing cycle, while the WTS production time must cover humiSonic production demand and ﬁ ll the vessel as quickly as possible.

The table below suggests the water consumption values and connections for all sizes of humidiﬁ ers.

(*) Water consumption during the washing cycle is calculated based on the default settings (1 wash every 24 hours, lasting 2 minutes, which ends by totalling ﬁ lling and emptying the volume of the tank). Consumption depends on the ﬁ ll solenoid valve ﬂ ow-rate, which is 2 litres/minute. The duration and frequency of the washing cycles are parameters that can be set by the user, and these have a signiﬁ cant impact on the sizing of the WTS system.

Important:

1. do not add disinfectants or anticorrosive compounds to the water, as these are potential irritants;

2. the use of well water, industrial water or water from cooling circuits and, in general, any potentially chemically or bacteriologically contaminated water is prohibited.

2.6 Drain water

This is not toxic and can be drained into the sewerage system, as deﬁ ned by directive 91/271/EEC on urban waste-water treatment.

3. ELECTRICAL CONNECTIONS

3.1 Humidiﬁ er electrical connections

Important

Important:

• before proceeding with the electrical connections, ensure that the

control panel – humidiﬁ er system is disconnected from the mains power supply;

• make sure that the power supply voltage of the control panel

corresponds to the value indicated in the rated data.

To power up the humidiﬁ er, connect the cables running from the electrical panel:

1. +48 Vdc/ -48 Vdc from the power supply;

2. +24 Vac/ -24 Vac from the transformer;

3. the power cable for the lights (“Slave” electrical panel only);

4. the cable for the signal lights (“Slave” electrical panel) or RS485 serial

line (“Master” electrical panel).

After having removed the screws (A), remove the side cover (B) and run the cables through the cable glands on the case and inside the unit (C). Then make the electrical connections (D) and reposition the cover, repeating the same operations in reverse.

HUMIDISTAT OR REMOTE CONTACT (ON/OFF action)

Production is enabled by closing the ONOFF – COM contact on the terminal block. This can be connected to a switch, a humidistat or a controller (voltage-free contact, max 5 Vdc open, max 7 mA closed).

RS485 SERIAL CONNECTION CAREL/ Modbus protocol: -TXRX-, +TXRX, 0TXRX terminals.

Important

Important: for RS485 connections in household (IEC EN 55014-1)

and residential (IEC EN 61000-6-3) environments, use shielded cable (with shield connected to PE both on the terminal and controller ends), maximum length speciﬁ ed by the EIA RS485 protocol, equivalent to European standard CCITT V11, using AWG26 twisted pair cable; the input impedance of the 485 stage is 1/8 unit-load (96 kOhm). This conﬁ guration allows a maximum of 256 devices to be connected, with cables in separate conduits from the power cable.

ALARM RELAY

Terminals: AL_B, AL_A Ready for remote signalling of one or more alarms.

Note: in industrial environments (IEC EN61000-6-2) the signal cables leaving the unit must not exceed 10 m (33 ft) in length: remote on/oﬀ digital input (ON/OFF - COM terminals) and shielded cable for RS485 communication.

3.8 Connection cable sizing

The table below shows the sizing of the 48 Vdc connection cable between the humidiﬁ er and the “Slave” or “Master” electrical panel. The minimum cross-section depends on the length. Use cable for working voltages ≥ 300 Vac and operating temperatures ≥ 90°C.

4. STARTING AND USER INTERFACE “SLAVE” PANEL

Before starting the humidiﬁ er check:

• water connections: in the event of water leaks, do not start the

humidiﬁ er before having restored the connections;

• electrical connections between the humidiﬁ er and the control panel.

4.1 Starting

See chap. “Electrical connections”

1. The humidiﬁ er, once powered and enabled for production (remote on-

oﬀ /humidistat), is ready for operation.

2. Operation will only stop if the enabling signal is no longer present.

4.2 Shutdown / Standby

1. To switch the humidiﬁ er oﬀ , press the ON/OFF button.

2. The humidiﬁ er goes into standby when:

• the remote on/oﬀ contact is open;

• the on/oﬀ contact is open and serial enabling is set to 1 (see

chapter “Humidiﬁ er control via network“).

When the humidiﬁ er is in standby, the tank is emptied automatically

4.3 Autotest

When the humidiﬁ er is ﬁ rst started (from oﬀ ), if enabled and humidity production is required, a test cycle is run. A complete ﬁ ll and drain cycle is performed, during which the level sensor is monitored; if the test is successful, regular atomised water production will start. If the test fails, production is disabled (see the alarm table).

4.4 Signal lights on the “Slave” panel

Blue light Steady Humidity production Slow ﬂ ash* Standby Fast ﬂ ash** Autotest or wash

* Slow ﬂ ash: 1 s ON and 1 s OFF ** Fast ﬂ ash: 0.2 s ON and 0.2 s OFF

The red LED means an alarm is active. See the chapter on Alarms for the alarm table.

4.5 Disabling

The humidiﬁ er can be disabled in three diﬀ erent ways:

• Opening the COM-ONOFF contact (enabling signal);

• Active alarms;

• Via network.

4.6 Reset tank hour counter

The humidiﬁ er is ﬁ tted with an hour counter that records operation. After a set number of hours (5,000), a signal is activated to indicate maintenance should be performed on the tank and operation of the piezoelectric elements checked (see the chapter on Maintenance). To reset the hour counter at any time, proceed as follows:

• switch the humidiﬁ er oﬀ ;

• close the water supply tap and wait for the tank to empty completely;

• remove the front panel from the humidiﬁ er to access the control board;

• unplug the Lumberg connector on the control board;

• open the On/Oﬀ contact;

• switch the humidiﬁ er on (with the Lumberg connector disconnected

from the control board). Both lights will ﬂ ash;

• close the On/Oﬀ contact. The yellow LED will remain on steady;

• switch the humidiﬁ er oﬀ ;

• plug the Lumberg connector (A) onto the board, making sure it is

inserted in the correct direction;

• switch the humidiﬁ er on.

Fig. 4.a

4.7 Automatic washing

The humidiﬁ er automatically runs a washing cycle at set intervals (default 60 minutes) during which time atomised water is produced. The washing cycle involves a complete drain cycle, a phase in which ﬁ ll and drain are activated together (1 minute) to ﬂ ush out any residues in the tank, a complete ﬁ ll cycle and ﬁ nally another complete drain cycle. During this operation, atomised water production is stopped.

4.8 Washing due to inactivity

If the humidiﬁ er remains inactive (on but in standby) for an extended period (24 hours) a washing cycle is performed, as described in the previous paragraph. This cleans the tank of any residues (e.g. dust) that may have accumulated during the period of inactivity. The washing cycle is run after 24 hours (continuous) of no operation, i.e. the humidiﬁ er is in standby.

2. if there is no water, it may be useful to extend the delay time before restarting, to avoid a premature no water alarm;

3. the alarm relay can be normally open (N.O.) or normally closed (N.C.); the solenoid valve in standby can be set as open or closed;

4. the “drain delay in standby” time is only set if the drain solenoid valve is selected as open in standby. This determines in delay for opening the drain solenoid valve after switching to standby. It is useful in the event of frequent starts/stops, to minimise the time needed to reach steady operation.

The built-in electronic controller on humiSonic features diﬀ erent control algorithms, which can be selected from the user menu:

On/Oﬀ : operation in on/oﬀ mode requires the connection of an external voltage-free contact to input HST (for example, a humidistat, see terminal block). Unit capacity will therefore be all or nothing, according to the status of the external contact. The humidistat logic deﬁ nes whether production is active with the contact closed (N.C.) or with the contact open.

As in the previous case with limit humidity probe, normally installed downstream of the droplet separator. The limit humidity probe is usually set to a high value, e.g. 80% rH, so as to limit the maximum humidity level in the ducting and in the room. This is especially recommended in installations where the air ﬂ ow-rate and temperature and humidity conditions may vary over time, and consequently an additional safety feature is useful for preventing the humidiﬁ er from over-humidifying the air and, in the worst case scenario, leading to condensation in the ducting downstream of the unit.

Atomised water ﬂ ow-rate can be modulated as a percentage from 10% to 100% of the rated capacity. Each humidiﬁ er is managed with two groups of transducers (front and rear) and each line is generates 50% of total production. If the request is set by the external signal (if proportional control is active) and the Max prod parameter is 100%, both the lines of transducers will be activated. For lower output, production will be shared between the two lines of transducers as follows:

• 51% - 99%: one line of transducers is always activated to generate 50%

of required production, while the other modulates as described in the previous paragraph to generate the remaining percentage. (e.g. 75% request: one line of transducers is always activated, the other modulates at 50%);

• 10% - 50%: one line of transducers is always oﬀ , the other modulates

as described in the previous paragraph to generate the required production (e.g. 25% request: one line of transducers is always oﬀ , the other modulates at 50%).

The distribution of production between the two lines of transducers is rotated every hour of operation so as to avoid non-uniform ageing.

7.7 Timings

The activation times are applied during unit operation and are used by the controller to detect any malfunctions.

7.7.1 Fill/drain times

Tmax ﬁ ll: maximum ﬁ ll solenoid valve opening time.

The humidiﬁ er detects when there is no feedwater (or the quantity is too low), by checking the level sensor status after opening the ﬁ ll solenoid valve. If the tank is empty, and sensor activation is not detected within the time set by parameter “Tmax ﬁ ll” (default 2 minutes), the humidiﬁ er is not activated, rather the drain valve opens, after which there is a waiting time equal to the number of minutes set by parameter “Restart wait” (Fc01, default 10), during the which is the message is shown on the display:

Waiting (Restart: xx minutes)

xx displays the minutes remaining until restart (starting from the value set for Fc01), after which there is another reﬁ ll attempt. If this is successful, production restarts, otherwise there is a further “Restart wait (Fc01)” for the set number of minutes. The process is repeated until the sensor detects water is present. For the ﬁ rst two attempts, no alarm is generated, however if after the third attempt the procedure is not successful, alarm EF is generated, which is reset automatically when the humidiﬁ er detects water is present again. If the water ﬁ ll cycle occurs during atomised water production, see the paragraph “Tmax reﬁ ll”.

Tmax drain: maximum drain solenoid valve opening time.

The humidiﬁ er detects when the water fails to drain (or the level is too high), by checking the level sensor status after opening the drain solenoid valve. If sensor activation is not detected within the time set by parameter “Tmax drain” (default 60 s), the humidiﬁ er keeps the drain solenoid valve open and activates the wait procedure, as described in the previous paragraph, displaying alarm Ed. The humidiﬁ er will reset the alarm and resume normal operation when the low water level is correctly measured.

ENG

“humiSonic ventilation” +0300063EN - rel. 1.0 - 16.02.2016

Empty drain T: time during which the drain solenoid valve remains open

after correctly measuring the low water level.

Following the water drain cycle, this is the time that must elapse after the level sensor measures the low water level to ensure the tank is completely emptied. This is useful if for parameter Fc03 the drain solenoid valve has been selected as closed in standby.

Tab. 7.m

Production, reﬁ lling times

Tmax prod: maximum atomised water production time (drivers active),

during which the level sensor must signal low water level.

Max Hlev time: maximum time for measuring the high water level.

The humidiﬁ er checks the water level in the tank during production of atomised water. If the level does not fall, the following faults may have occurred:

1. piezoelectric transducer malfunction;

2. leaking ﬁ ll solenoid valve;

3. fan malfunction.

If after the time set for Tmax prod (in minutes, default 30), the low water level has not been reached, atomised water production is stopped and the wait procedure starts (see the description in Tmax ﬁ ll), after which the control attempts to resume production. If the condition remains, alarm EP will be activated, shutting down the unit. If after a percentage of Tmax prod, set on screen Gea03 (default 70%) the water level is above the high level for a time equal to “Max Hlev time”, atomised water production stops and warning EL is generated. The wait procedure then starts, after which the controller will attempt to restart production. Warning EL is reset at the end of a production cycle that ends correctly. Alarm EL is also generated during standby if an abnormal water level is measured (the water level diﬀ ers from the level measured when switching to standby, for a time equal to Max Hlev time).

Tmin prod: minimum atomised water production time (driver active)

during which the low level sensor must not be activated.

Tmin prod sets a minimum production time (default 1 minute). If the production cycle lasts less than this time, the drain solenoid valve may not be tight or the ﬁ ll solenoid valve ﬂ ow-rate may be too low. The controller, in this case, activates the following procedures:

1. at the end of the ﬁ rst cycle, ending after less than Tmin prod, the Reﬁ ll time is increased (50% more than Reﬁ ll time) and the drain solenoid valve is powered at a higher voltage to try and increase tightness;

2. at the end of the second cycle, ending after less than Tmin prod, the water reﬁ ll time is further increased (100% more than Reﬁ ll time) and chattering* of the drain solenoid valve is activated during the ﬁ rst automatic washing cycle;

3. at the end of the third cycle, ending after less than Tmin prod, the water reﬁ ll time is further increased (150% more than Reﬁ ll time) and a washing cycle is performed, including chattering* as activated in the previous step. Warning Ed will also be generated.

4. following the last stage, a new production cycle will be performed.

If the cause of the error persists, the controller will start the procedure from the beginning again, until it a full cycle is completed within the deﬁ ned times. Any warnings will also be reset.

*Chattering: series of rapid opening/closing cycles of the drain solenoid valve, aimed at removing any residues (scale, dust, etc.) that prevent it from closing correctly.

Reﬁ ll time: time the ﬁ ll solenoid valve is kept open for, after the control level (intermediate) has been reached during atomised water production.

Tmax reﬁ ll: maximum time the drivers remain active for during a water reﬁ lling cycle, after the level sensor has measured the low water level during atomised water production.

The piezoelectric transducers, by nature, if operated without water, will be quickly damaged until failing. To prevent this from happening, the controller ensures, via the level sensor, that even in the event of malfunctions the transducers are never activated without water present. When starting with an empty tank, the transducers are only activated when the low level is measured and, subsequently, the “Reﬁ ll time” has elapsed. During reﬁ lling when the unit is operating, that is, after the low level has fallen due to atomised water consumption with consequent activation of the ﬁ ll solenoid valve, if the level is not restored before the “Tmax reﬁ ll” time, the transducers are switched oﬀ , while the ﬁ ll cycle continues until:

1) the level has been restored and the “Reﬁ ll time” has elapsed. The transducers are then reactivated

2) on activation of the ﬁ ll valve, the time set for Tmax ﬁ ll must elapse. Then the wait procedure will be activated, as described previously. If, on the other hand, the level is correctly restored within the “ Tmax reﬁ ll” time, the transducers remain on and the ﬁ ll cycle continues until the end of the Reﬁ ll time.

Low lev delay: low level ﬁ ltering time for activating the ﬁ ll cycle.

The ﬂ oat sensor must remain active for the time set by Low lev delay before the ﬁ ll cycle (Reﬁ ll) or the complete emptying timer (Empty Drain) is activated).

Unit oﬄ ine alarm times

Remote board oﬄ ine time: time after which the remote unit is deactivated

(standby) if there is no serial connection with the control panel.

The remote unit checks communication status with the “Master” panel, and if for some reason there is no communication for the time set for the parameter, the unit goes into “safety” mode, that is, atomised water production is stopped and the drain cycle is activated.

Main board oﬄ ine time: time after which the control panel generates the “Remote unit oﬄ ine” alarm if no serial communication is detected.

If the “Main board oﬄ ine time” elapses, and the control panel continues to not receive a response, the “Remote unit oﬄ ine” alarm is activated. In this status, atomised water production can no longer be activated.

9. ALARMS

9.1 Types of alarms

There are two types of alarms:

• manual reset;

• automatic reset: the alarm is reset and the unit restarts automatically

when the alarm condition is no longer present; When an alarm occurs, the Alarm button ﬂ ashes and the display shows the standard display.

Press Alarm to display a short description of the alarm. Press Alarm again to attempt to reset the alarm:

1. if the cause is no longer present, the alarm should be reset and the red

light on the button will go oﬀ ;

2. if the reset attempt fails, the Alarm button stays on steady, signalling that

the alarm has been acknowledged.

If the alarm is reset automatically, the Alarm button goes oﬀ and the alarm reset event is recorded in the alarm log.

Example: the high humidity alarm is visible in the list of alarms, and the log shows the activation event (down arrow) and reset event (up arrow).

10.4 Maintenance

Important: before performing any operations:

• power the unit oﬀ at the switch (oﬀ ) on the control panel;

• empty the water from the tank.

The ﬁ ll valve is normally closed and the drain valve is normally open, consequently, when powering down the humidiﬁ er, the unit is drained automatically.

Note: preventive maintenance on the humidiﬁ er is recommended

to ensure optimum system performance. Maintenance includes:

• checking tightness of the electrical connectors;

• cleaning and visual inspection of the components;

• checking water level and making sure there are no leaks.

Important:

• the piezoelectric transducer is very delicate: when cleaning the inside

of the tank, make sure not to scratch it, for example with a screwdriver;

• tighten the nuts applying the maximum allowed torque (4 ± 0.5

kg·cm). Excessive tightening torque may damage the humidiﬁ er.

10.5 Maintenance operations

Routine maintenance on humidiﬁ ers operating on demineralised water involves cleaning all the parts in contact with the water: a. ﬁ ll/drain lines; b. water tank.

Special maintenance and repairs involve replacement of: a. ﬁ ll/drain solenoid valve; b. driver board; c. piezoelectric transducer; d. electronic control board.

10.6 Maintenance intervals

Maintenance intervals depend on water quality and the quantity of atomised water produced. An operating hour counter (eﬀ ective production) and a unit operating hour counter (total hours) can be set, together with a maintenance hour counter, after which the display shows a warning message. See alarm CL.

Piezoelectric transducer

Note: the atomisation capacity of the piezoelectric transducer

gradually decreases with use. It must be replaced after around 10,000 operating hours (depending on water quality), even if the unit can continue operating while eﬀ ective capacity still responds to requirements.

To remove the piezoelectric transducer:

1. turn the humidiﬁ er body over and identify the piezoelectric transducer

to be replaced;

2. unplug the electrical cable terminals from the corresponding driver

board;

3. using a socket wrench (5.5), loosen the fastening nuts, remove the

transducer and replace it;

4. when replacing the transducer, pay attention to the white markings

(arrow): the top line of transducers has the markings on the right, and the bottom line has the markings on the left. The transducer must have the markings positioned in the same ways as the adjacent ones.

Note: the tightening torque of the nuts that fasten the transducer

must be 4±0.5 kg cm

Important: if the transducer is ﬁ tted rotated 180°; incorrect

assembly will cause a reduction in atomised water production and potential humidiﬁ er malfunctioning.

12. MULTIUNITS INSTALLATION

12.1 Connection master-slaves (until 4 humisonics)

In order to optimize the control and management of multiple humidiﬁ ers within the same conduct, it is possible to connect them in serial following the diagrams reported below.

Setup

The “Master” unit is able to control the operation of a maximum of 3 “Slave“ units connected via tLan network. For electrical connections refer to diagram in ﬁ g.12.1.a and 12.1.b. The Master unit’s dipswitches 1-3 must be all set to OFF. Each slave unit must be properly conﬁ gured via the following dipswitches:

1: Set to ON for the conversion of the serial port (M11) from 485 to tLan. 2/3: Slave address, as shown on page 2 (See Sect. 4 of Manual cod.

+0300056IT-EN).

Control logic

The Master unit controls each “Slave” unit, through the following parameters:

• Enable / Disable the operation

• Level of production of atomized water

The control signals (probes / humidistat / external regulator) are read and handled only by the Master who shall then adjust the operation of the slave. The production level of the Master is replicated by all the Slave units.

13. DUCT INSTALLATION

If several Humisonics are to be installed into the same duct , it is necessary to arrange them within the duct so as to obtain a homogeneous and constant atomization.

Suggested installative layouts are:

• “On line” layout: units are positioned on diﬀ erent levels along the same

vertical section. The diagram 13.1 shows the minimum distances for humidiﬁ ers placement within the same duct:
