1. GENERAL DESCRIPTION AND MODELS

ENG

1.1 General description

humiFog Direct is a direct humidier for room installation. It consists of a pumping unit (also called the cabinet) and a distribution system (comprising blower units) to be installed directly in the room to be humidied and cooled. The pumping unit is connected to the blower units by high pressure hoses. The cabinet is tted with a pump that delivers water at high pressure (70 bars) to the nozzles on the blower units, where it is atomised into very ne droplets that evaporate spontaneously.

The cabinets are available in the single zone and two-zone version. The latter can manage two independent zones, reading two separate signals (from a probe or external controller).

For all models, the minimum ow rate that can be supplied by the pump is 10% of its nominal ow rate. For this reason, it is recommended to couple a distribution line that can atomise a ow-rate of water equal at least to the minimum ow-rate delivered by the pump.

It is important to install the distribution system in a suitable environment (in terms of volume, air change and operating temperature) so as to ensure absorption of the atomised water. Carel can provide support for calculating the required humidication load.

1.2 Operating principle

System operation is based on a request signal from a probe (temperature or humidity) or external controller. When operation is enabled (remote on/o ) and at the same time there is a humidication or cooling request signal, the system opens the ll solenoid valve and activates the pump, which pumps the water at high pressure (70 bars). After having also opened the outlet solenoid valve, the initial stage of operation begins, involving washing and lling the line, after which, when the line is lled and pressurised, the nozzles will start spraying water. Modulation is available in PWM mode (pulse width modulation): the controller alternates a time (set on the display) in which the outlet solenoid valves are operation, thus atomising the water, with period in which the outlet valves are closed and the bypass valve is open, thus interrupting atomisation into the room. The set point is managed directly by the electronic controller using a proportional band (P+I) or an oset when reaching the set point. On reaching the set point, the system stops and enters standby mode, restarting when there is a new request. For this reason, the system should be powered on at all times.

1.4 Hose part numbers

The high pressure hoses (OD = 10 mm, ID = 6.4 mm) are supplied by Carel in dierent lengths. The part numbers available are listed below. All the hoses have with M16x1.5 female couplings with O-rings, ideal for direct connection to the cabinet and the blower units without needing to use sealants. Each hose kit includes an M16x1.5 nipple to be used for coupling dierent hoses together. Stainless steel pipes can also be used to connect the blowers to the cabinet. The recommended outside diameter is 10 mm. This solution is the installer’s responsibility. Carel recommends using hoses rather than pipes.

2. CABINET INSTALLATION

ENG

2.1 Positioning

The cabinet, being IP20, must be installed in a closed compartment, sheltered from the rain, water spray and direct sunlight. The cabinet must be installed in an environment with a temperature between 5 and 40°C. Around 1 m clearance must be left in front of the cabinet to allow the door to be opened and maintenance to be performed. Around 0.5 m clearance needs to be left on both sides of the cabinet to allow space for the water connections on the right and electrical connections on the left.

Fig. 2.a

2.1.2 Floor-standing installation

For oor-standing installation, the unit needs to rest on a raised platform so as to allow connection of the drain hose, located on the bottom of the cabinet (see chapter 2.2.3).

min 30 cm

Fig. 2.c

2.2 Cabinet water connections

2.1.1 Wall mounting

The cabinets can be wall-mounted or oor-standing. In the event of wall mounting, it is recommended to use the metal frames and screws supplied. See the distances shown in the following image for drilling the holes and fastening the brackets.

2.2.1 Feedwater line

An expansion vessel should always be installed upstream of the cabinet, so as attenuate variations in pressure in the feedwater line. It is also suggested to install a mechanical lter on the feedwater line to the cabinet (P/N ECKVESS050 for the lter vessel and P/N ECKFILT050 for the lter cartridge). Finally, an on-o ball valve should be installed on the line upstream of the cabinet, so as to allow for any maintenance operations on the water circuit downstream.

Fig. 2.d

A hose with a minimum diameter Ø=1/2” should be connected upstream of the cabinet so as to ensure the right ow-rate and pressure to the humidier. The humidier inlet connection is 3/4” GAS F. The required humidier inlet pressure is at least 3 bars.

Fig. 2.b

"humiFog direct" +0300073EN rel. 1.2 - 02.05.2019

ENG

2.2.2 Feedwater characteristics

humiFog Direct requires demineralised water, so as to ensure:

• minimum maintenance;

• no blockages of the nozzles;

• no dust (the droplets that evaporate will not leave mineral salts in the

environment);

• improved hygiene.

The use of demineralised water is also required to comply with standards UNI8883, VDI6022 and VDI3803. humiFog Direct must only operate on demineralised water that falls within the limits listed in the following table. Normally, these values can be obtained by reverse osmosis or nanoltration of the feedwater.

3. DISTRIBUTION SYSTEM INSTALLATION

3.1 Blower unit installation

The humiFog Direct system works by connecting the cabinet to a number of blower units installed directly in the room to be humidied and/or cooled. The following simple rules must be kept in mind when installing the blower units:

• the minimum ow-rate that can be atomised in the room is 8 l/h

(irrespective of the size of the pump). The minimum number of blower units must therefore be dened based on the number and size of the chosen nozzles.

The maximum numbers of blower units that can be connected to a cabinet are:

• 12 blower units with 2 nozzles

• 6 blower units with 4 nozzles

• 3 blower units with 8 nozzles

The blower units must be suitably positioned so as to allow complete absorption of the sprayed water. Consequently it is recommended to install the blowers a due distance apart, at a sucient height from the oor and with free space at the front without obstacles.

ENG

The blower unit installation procedure is as follows:

1. Unpack the blower unit from the box it was delivered in. The blower

units are delivered fully assembled.

2. Remove the side plastic covers cover from the blower. Unscrew the

long screws on the side using a screwdriver. Make sure to keep the screws, as they will be needed again for assembly at the end.

3. Mount the blower unit on the metal support. See paragraph 3.2 for

details.

4. Connect the water line to the inlet on the blower units (M16x1.5). See

paragraph 3.3 for details.

5. Electrically connect the blower units to the cabinet, which supplies

power and controls operation of the fans. See paragraph 3.4 for details.

6. Complete blower assembly by repositioning the side plastic covers

removed previously, and xing them with the same screws as removed at the beginning.

3.2 Mounting single blower units on the wall / ceiling

The single blower units (P/N DLA%F) are designed to be installed on a vertical wall using a special metal support to be xed to the wall using screws. Check that the wall is made from suitable material and is able to support the weight of the blower unit (concrete, not plasterboard).

Then attach the blower to the protrusions on the wall-mounting support bracket. Fix the blower unit to the bracket using the screws supplied in a bag inside the packaging.

Fig. 3.e

When tightening the rst screw (M6 self-tapping in Ø=5.5 mm holes), slightly loosen the screws on the ring clamps that support the nozzle manifold, so as to be able to turn it and free up space to continue mounting the unit. Tighten one screw on the right and one screw on the left. Then tighten the third screw (M4 self-tapping in Ø=3.5 mm hole) on the right-hand side of the blower (opposite the terminal block). When tightening this screw, the angle of the blower can be adjusted between

-10°/-5°/0°/+5°/+10° from horizontal, using one of the ve small holes provided.

Then make the water connections, connecting the feedwater line either on the right or left of the blower, and the water return line on the opposite side.

Fig. 3.b

First remove the blower unit from the packaging and take o the side plastic covers. Remove the blower unit from the steel bracket on the rear.

Rest the bracket against the wall in the position where the blower will be installed, and then drill four holes in the wall, using the steel bracket as the drilling template.

Fig. 3.c

Fig. 3.d

After having drilled the holes in the wall, x the metal support using anchor screws (not supplied).

Fig. 3.f

Finally, t the two cable glands and complete the electrical wiring, as described in paragraph 3.4.

Carel also provides an additional kit (including a special plate bent at 90°) for mounting single blower units on the ceiling.

Fig. 3.g

"humiFog direct" +0300073EN rel. 1.2 - 02.05.2019

3.3 Mounting double blower units on the ceiling

The double blower units (P/N DLA%B) are designed to be installed on the ceiling by anchoring them to a metal support that can support their weight and the vibrations due to the pressurised water. To mount the blower unit, use the special attachments provided on the unit’s metal structure.

Carel provides additional kits with everything needed to complete installation easily. Make sure to carefully choose the point where the vertical support bar will be anchored. The support bar must not be longer than 1 metre, so as to avoid excessive bending and vibrations.

Fig. 3.h

After installing the blower, make the water connections by connecting the feedwater and return lines to the two pipes provided on the top of the blower. The feedwater/return lines can be connected either to the right or left.

ENG

Fig. 3.i

Finally, t the two cable glands and complete the electrical wiring, as described in paragraph 3.4.

3.4 Blower unit electrical connection

The blower units must be electrically connected to the cabinet so that they are activated only when there is a humidication request

Before electrically connecting the blower units to the cabinet, make sure that the cable glands supplied with the cabinet and the blower units are available. All connections to be made by the user (cabinet power supply, blower unit power supply, probe connections, etc.) must be performed by running the cables through the cable glands, and in accordance with local safety standards.

Also check that the cable is the right size for the distance and voltages used. Carel recommends an AWG14 or AWG12 cable, as shown in the technical data at the end of the manual.

To connect power to the blower units, connect three suitably-sized wires (line + neutral + earth) from the terminals on the cabinet (shown in the gure) to the terminals on the blower (shown in the gure). To power a second and subsequent blowers, start from the free terminals on of the previous blower and connect to the terminals on the next blower, as shown in the gure.

Fig. 3.j

Important:

• remember to run the wires through the cable glands (marked in the gure).

• check the maximum number of blower units that can be connected to each cabinet in the tables in Appendix 12 at the end of the manual.

• when connecting the line (L) and neutral (N) from the cabinet to the blower units, never reverse L and N. Reversing or crossing over the wiring may cause

short-circuits.

After having completed the wiring, close the side plastic covers again and x them using the screws. The system is now ready to operate.

4. ELECTRONIC CONTROLLER SET UP AND CONNECTIONS

After having correctly installed the cabinet and completed the water and electrical connections, connect the signals used to interface with the humiFog Direct humidier to the c.pHC electronic controller (and the c.pCO controller on two-zone cabinets.

Fig. 4.a

4.1 Remote ON/OFF signal connection

The remote ON/OFF contact is used to enable operation from an external device. It is a digital contact that can be either open or closed: when the terminal is open, humiFog cannot operate. The contact refers to inputs 7 [GND]- 8 [digit] on terminal M2 on the c.pHC. The remote ON/OFF contact must not be confused with the ON/OFF signal that manages operation, described in paragraph 4.5.

The following types of probes are allowed:

• 4-20 mA, 0-20 mA current probes

• 0-10 V, 0-1 V, 2-10 V voltage probes

The analogue signal from the limit probe in the rst zone is connected to the c.pHC controller via inputs 5 [IN a] 6 [GND] 3 [+12 Vdc] on terminal M2.

MAIN PROBE

ZONE 1

[IN a] [GND] [+15 Vdc] [IN a] [GND] [+15 Vdc]

Important: if connecting a probe with voltage signal that requires a power supply greater than the +12 Vdc supplied to the terminal on the c.pHC, the third wire must not be connected to input 3 [+12 Vdc] but rather to terminal GA1 [+24 Vac], made available on the cabinet terminal block, right above the c.pHC.

LIMIT PROBE ZONE 1

Fig. 4.c

7 [GND]8 [digit]

Fig. 4.b

If not intending to use an external contact to start / stop the unit, leave the terminal short-circuited (as supplied).

REMOTE ONOFF

4.2 Analogue signal from the main probe and limit probe in the ﬁrst zone

humiFog Direct can be controlled using an analogue signal (modulating) from a main humidity or temperature probe connected to the c.pHC electronic controller. If connected to a humidity probe, humiFog Direct will display the relative humidity read by the probe. If connected to a temperature probe, on the other hand, humiFog Direct will display the temperature. Based on the probe reading and the deviation from the set point, humiFog Direct will modulate the humidication load according to the PWM principle (see paragraph 6.2). The following types of probes are allowed:

• 4-20 mA, 0-20 mA current probes

• 0-10 V, 0-1 V, 2-10 V voltage probes

The analogue signal from the main probe in the rst zone is connected to the c.pHC controller via inputs 1 [IN a] 2 [GND] 3 [+12 Vdc] on terminal M2.

4.3 Analogue signal from the main probe and limit probe in the second zone

If a second zone is used (only with UA%DD201 and UA%DU201 cabinets), the main probe corresponding to the second zone must be connected to the c.pCOe expansion installed under the c.pHC controller.

The following types of probes are allowed:

• 4-20 mA, 0-20 mA current probes

• 0-10 V, 0-1 V, 2-10 V voltage probes

The inputs used for the main probe are U1 [IN a] and [GND] on terminal J2, and the power supply is taken from the +Vdc on terminal J9. The limit probe (optional) corresponding to the second zone is connected to inputs U2 [IN a] and [GND] on terminal J2, and the power supply is taken from the +Vdc on terminal J9.

MAIN PROBE

ZONE 1

[IN a] [GND] [+15 Vdc] [IN a] [GND] [+15 Vdc]

LIMIT PROBE ZONE 1

The limit probe (optional) is used for the auxiliary function to reduce humiFog Direct humidication or cooling capacity when approaching a set humidity or temperature threshold (on the display or external controller). To set the threshold, select operation with limit probe on the display. The threshold will either be a humidity or temperature value. The limit probe can also be used without using a main probe.

"humiFog direct" +0300073EN rel. 1.2 - 02.05.2019

Fig. 4.d

Important: unlike the rst zone, the connection to the c.pCOe expansion relating to the second zone can supply power to probes that require up to 21 Vdc.

ENG

4.4 Analogue signal from an ext. controller

As an alternative to the main probe, a signal from an external controller can be used. The latter processes the request to send to humiFog Direct via an analogue signal, which varies from 0 to 100%. humiFog will adjust the capacity delivered proportionally to the signal received, and the display will show the request sent as a percentage.

The following types of proportional signals are allowed:

• 4-20 mA, 0-20 mA current signals

• 0-10 V, 0-1 V, 2-10 V voltage signals

The external signal for the rst zone is connected to the c.pHC controller via inputs 1 [IN a] and 2 [GND] on terminal M2. The external signal for the second zone is connected to the c.pCOe controller via inputs U1 [IN a] and [GND] on the terminal J2.

EXTERNAL SIGNAL ZONE 1

[IN a] [GND] [IN a] [GND]

The limit probes can also be associated with the external proportional signal, and will be connected as shown in the previous paragraphs.

Fig. 4.e Fig. 4.f

EXTERNAL SIGNAL ZONE 2

4.5 Digital signal from humidistat or external controller

The signal from the external controller can be replaced by the signal from a humidistat, thermostat, or any external device with digital contact. In this case, humiFog Direct will work in ON/OFF mode, either delivering 100% of ow-rate or remaining in standby. The capacity delivered can be reduced by setting parameter P0 (the reduction is managed by PWM, see paragraph 6.5). The electrical connection is the same as in the previous case shown in Figure 4.e. Make sure to congure the humiFog Direct (via the screens on the display) so that it can be controlled by an ON/OFF signal from external controller or device.

4.6 Serial or Ethernet communication

humiFog Direct can be controlled by a supervisor that reads the humiFog Direct parameters and sends commands. To connect a supervisor, the RS485 serial port (terminal M12, inputs 1 [Tx/Rx-] 2 [Tx/Rx+] 3 [GND]) or Ethernet port is used. The choice of which port to use depends on the supervisor. Modbus and BACnet communication protocols are available as standard: no auxiliary cards need to be tted on the c.pHC controller

The Ethernet port can also be used for the Webserver function (see Chapter 8), so as to monitor and control humiFog Direct via a local network, without needing a supervisor.

4.7 Alarm relay output

The digital output for communication of an alarm status is connected to contacts 1-2-3 on terminal M6 on the c.pHC. N.C. logic is set by connecting the two wires to contacts 1-2, while N.O. logic is set connecting the two wires to contacts 1-3.

N.C.

ALARM RELAY

Fig. 4.h

N.O.

4.8 Unit status digital output

The c.pHC controller provides a digital output corresponding to unit status. This is a voltage-free contact that provides the following information:

• contact closed: unit on or in standby

• contact open: unit o (OFF from keypad or from remote contact, or

no power)

The unit status digital output is available at contacts 1-2 on terminal M5 on the c.pHC.

4.9 Production percentage analogue outputs

The c.pHC controller provides an analogue output (0-10 V) corresponding to the percentage of production that humiFog Direct is delivering. The output replicates the request signal relating to the corresponding humiFog Direct zone. The production percentage analogue outputs are connected to the following terminals:

• zone 1: outputs 1 and 2 on terminal M8 on the c.pHC.

• zone 2: outputs U3 and GND on terminal J2 on the c.pCOe.

6.2.1 Modulation of production

The system modulates the atomisation of water intermittently, in PWM mode (pulse width modulation). Within a time period of 120 seconds (settable value), the unit will deliver pressurised water to the blower units for atomisation by the nozzles in the room:

• for 120 seconds continuously, when there is maximum production

request;

• for a fraction of time Ton less than 120 seconds (minimum 8% of the

entire period) and proportional to the request signal, if not at the

maximum. When atomisation stops, the pump remains active and the water is recirculated through an internal bypass circuit in the pumping unit, rather than being delivered to the blower units.

6.2.3 Autonomous control with humidity or temperature probes

When using a main humidity control probe and an optional limit humidity probe, atomisation is related to the % rH reading made by the relative humidity probe and increases as the value read deviates from the set point St. Maximum production Pmax corresponds to the case where the humidity value, read by the probe, is BP away (proportional band) from the set point. The activation hysteresis hy is not settable by the user.

For “humidity (one probe)” or “temperature (one probe)” control, one single main probe can be connected and congured, either wired or wireless.

For “humidity with limit” or “temperature with limit” control, a wired probe can be connected as the main probe and a wired probe as the limit. If using wireless probes (maximum of four), two groups of probes can be dened: the group of main probes and the group of limit probes. In this case, the average will be calculated between the main probes, depending on the dened weight, and the limit probes will also have their own average, again depending on the dened weight.

For “humidity (two probes)“ or “temperature (two probes)” control, only a group of main probes can be dened. Wired probes can be connected to the main probe input (M2.1) and the limit probe input (M2.5), which will be used as a second probe, with the average calculated. If using wireless probes (maximum of four), only a group of main probes can be dened, with the average calculated, depending on the dened weight.

For the connections of the signals and/or probes, see chap. 4.

6.2.4 Weighted average of the probes (installer menu)

If using two temperature probes or two humidity probes, the humidier controller will calculate the weighted average of the probe readings. In this way, two probes can be used, for example humidity probes, at opposite ends of the room, calculating the average.

6.3 Functions

6.3.1 Filling

For correct functioning of the system there must be no air in the lines, so as to avoid vibrations, long transients and low-quality atomisation. To eliminate all air, the lling time must be set correctly. When starting the system the rst time, measure the time required for the water to reach the end of the circuit, and wait only until water visibly comes out of the circuit. The longer the water circuit, the higher the lling time needs to be.

7. MASTER/SLAVE NETWORK OF HUMIDIFIERS

7.1 Description of the Master/Slave system

To extend humidication capacity in an individual zone, several humidiers can be connected together in a Master/Slave system. For example, if humidication request is 160 kg/h, a Master/Slave system can be created with two 80 kg/h humiFog direct single-zone unit. A maximum of 3 Slave units can be connected to a Master, meaning a total of 4 humidiers in the same system. The Master and Slave units are connected using a local Ethernet network, and in the case of just two units (one Master and Slave) involves a direct connection between the two unit controllers via Ethernet RJ45 Category 5 cable.

Fig. 7.a

If the Master/Slave system comprises three or more units (maximum 4), a network switch is required.

7.2 Network switch for Master/Slave connection

The Master/Slave connection of more than two units requires the use of an industrial grade switch. Carel markets a switch (P/N: KITSE08000) that can connect a maximum of eight units (8 Ethernet ports). If necessary, use several KITSE08000 switches with a cascaded arrangement.

Main technical specications of the KITSE08000 switch:

Number of ports 8 Installation DIN rail Operating temperature -10 to 60°C (14-140°F) Power supply 12/24/48 VDC

18-30 VAC (47-63Hz) Current @24VDC 0.13A Protection IP30

Tab. 7.a

7.3 Type of Master/Slave system installation

The Master/Slave system features one main unit (Master), which manages operation of the secondary units (Slaves). The external signal or probe connections, depending on the set control type, are made to just one of the humidiers in the system. The unit that the signal is connected to will automatically be identied as the Master. Consequently, the Master does not need to be especially congured..

The Ethernet port is available on the humidier’s c.pHC controller:

Note: use Ethernet CAT-5 STP cable, maximum length 100 m. To

connect the shield, use the earth connector provided on the controller.

"humiFog direct" +0300073EN rel. 1.2 - 02.05.2019

Fig. 7.b

Fig. 7.c

While the Master unit is powered on, the system will be able to operate even in the event of malfunctions on the Master (alarms, stopped production,…), as the unit’s controller will send all the required data to the Slaves. Obviously, unless redundancy has been factored into the total humidication capacity, this case will be lower than requirements. If the Master is switched o completely, the Master/Slave system will not be able to read the control/probe signals. Consequently, it is suggested to connect all the humidiers in the system (or at least two units) to the external signal or t them with independent probes.

7.4.1 Maximum Master/Slave system production

In the same way as for the individual unit conguration, for the Master/ Slave system the maximum capacity can also be set. To set the maximum capacity, go to menu Dd03. The “Capacity” parameter identies the maximum production request for the Master/Slave system, and can therefore be set by the user. The “Maximum capacity” parameter (read-only), on the other hand, indicates the sum of the sizes of each unit added to the system; this value is therefore the maximum eectively available to the Master/Slave system. Consequently, “Capacity” will always be ≤ “Maximum capacity”. In any case, the maximum production can be dened for each individual unit in the system by limiting production from its maximum according to the size. In this case, “Maximum capacity” will be updated keeping in consideration these reductions..

7.4.2 Unit production distribution logic in the Master/Slave system

The activation logic of the units in the Master/Slave system can be set, choosing between “Grouped” or “Balanced”, on screen Dd03. Grouped distribution

Fig. 7.d

Systems set up in this way will be able to cover the humidication requirement. In this specic case, the Master will always be the unit with the lowest IP address of those connected to the signal/probes. If necessary, an additional humidier (backup) can be installed to cover request in the event of malfunctions on one of the units in the system.

7.4 Master/Slave system conﬁguration

To congure the Master/Slave system, proceed as follows:

1. Connect the probes or the external signal to the unit and complete the

conguration (control type, type of signal, maximum production …);

2. Set the IP addresses of the individual units so that they belong to

the same subnetwork (subnet mask); the screen index for this conguration is Dh05 (D. Settings – g. Supervision). The IP address is set on the display on each unit, assigning a dierent address to each unit in the same subnetwork. If necessary, contact the local network administrator. Remember that the default address for each unit is

192.168.0.1, and the default subnet mask is 255.255.255.0. For further details see paragraph 8.1.1 “IP address and network conguration”

3. Connect the units making up the Master/Slave system to the local

Ethernet network via a switch. If using just two units, an RJ45 category 5 cable can be used, connected directly to the Ethernet ports on the two c.pHC controllers.

4. Congure the Master/Slave system by enabling the units one at a time

(this operation can be performed on the display on any of the units):

4.1 Display screen index Dd01 and then access conguration mode by pressing “PRG”.

4.2 Enter the IP address for “Unit 1” and conrm by pressing “ENTER”.

4.3 Repeat the operations described above (4.1 and 4.2) for all the other units in the Master/Slave system. (The units will join the Master/Slave system (online) immediately after being added to the network.)

Note: the Master unit will always (automatically) be the one with the lowest IP address out of the units connected to the probes or external signal.

Note: it may take a few seconds (max 10 s) for the Master to start sending the production request to the Slave/Slaves. This is also true when, automatically, the Master unit is changed (for example, in the event of malfunctions).

• the units are activated in series, one after the other, according to the

request. Example: M/S system comprising two 80 kg/h units, for a maximum total capacity of 160 kg/h. While the request remains below 50% (80 kg/h) only one unit will be activated (for example, Unit 1), as soon as the request exceeds the 50%, the second unit will also be activated (in the example, Unit 2).

Balanced distribution:

• the units are activated in parallel at the same time, splitting the total

production request between the number of units in the M/S system. Example: M/S system comprising two 80 kg/h units, for a maximum total capacity of 160 kg/h. If the request is 50%, both Unit 1 and Unit 2 will be activated at 50% of production (40 kg/h + 40 kg/h = 80 kg/h). If the request is 90% (144 kg/h), both Unit 1 and Unit 2 will be activated at 90% (72 kg/h + 72 kg/h = 144 kg/h).

For Grouped Distribution only, if the request does not require the use of all the units, the automatic rotation function can ensure that the individual units total the same number of operating hours. To enable and congure the operating hours for unit rotation, set the “auto-rotation time” parameter on screen Dd04.

Note: if the “auto-rotation time” parameter is = 0, the auto-rotation

function is disabled.

7.4.3 Disconnect unit from the Master/Slave system

To remove a unit from the Master/Slave system, thus reducing the number of units available in the system, use the “Disconnect unit” function on screen Dd06. This can be done on any of the humidiers in the system.

Note: once the unit has been disconnected, this will no longer be visible in the Master/Slave system, as its IP address will be removed from the list. If a unit is disconnected erroneously, the system can be restored on screen Dd01 (entering its IP). This must be done from the display on a unit that is already connected to the system.

7.4.4 Display Master/Slave system

To display a summary of the Master/Slave system, go to screen Dd08. The menu displays all the units (01, 02, …), the status of each unit and current production as a percentage. The following table lists the Master/ Slave network unit status indications:

Symbol Unit status in the Master/Slave system

The units in the Master/Slave system can also be selected one by one, displaying maximum production, unit status, operating hours, current production request and any alarms. To enter this display, from screen Dd08, select the desired unit and press

display the details of all the units.

, thus accessing screen Dd09. Scroll using the UP/DOWN buttons to

7.4.5 Software backup function in the Master/Slave system

Master/Slave mode can also be used to manage the software backup function; if one or more units in the Master/Slave system is aected by a malfunction, the system automatically restores humidity production by activating the backup units. The lost production in relation to the humidication request is thus compensated by increasing production on the individual units (where possible) and/or starting any units in standby.

Even if not strictly necessary, to ensure the backup function, the external control signal must be sent to all the units in the Master/Slave system; if using probes on the other hand, each unit must be tted with a probe. Only in this way can complete operation be guaranteed in the event of malfunctions.

Note: if a unit goes oine due to a malfunction or shutdown, it will temporarily be excluded from the system, and when next restarted it may take 15 seconds or more to automatically come online status again.

8. CONNECTIVITY



ENG

8.1 Webserver

The web server is a very interesting function when the user has a local network available that humiFog Direct can be connected to. The physical local network connection uses the Ethernet port with RJ45 connector on the humidier controller (see Figure 4.G) and a normal Ethernet cable (category 5). The integrated web server on the humiFog Direct c.pHC controller is used to congure and monitor the main unit parameters directly from a PC, tablet or smartphone. By opening an internet browser, the humidier can be accessed from the local network via the humiFog Direct unit’s IP address.

8.1.1 IP address and network conﬁguration

An IP address is a numerical code that identies the modem, computer, smartphone or any other device connected to a network, so as that these can communicate with one another. Typically the IP address of multiple devices connected to the same network is identical, except for a few numbers.

EXAMPLE:

• 192.168.1.1 device #1 connected to the network

• 192.168.1.2 device #2 connected to the same network

• 192.168.2.25 device #3 connected to the same network

Remember that when wanting to connect several devices to the same network, a switch is required (this can be supplied by Carel, P/N KITSE08000).

The IP address of the humiFog Direct unit is shown on the display, under:

• D. Settings

• d. Unit networks

• g. Supervisor

Dg05. Ethernet supervision port conguration: DHCP and IP address

With a static IP address (with DHCP OFF as by default), on screen Dg05 enter the network parameters manually, as provided by the local network installer. Usually subnet mask and gateway have predened values (which must be known), while the IP address can be assigned sequentially in relation to another device connected to the same network.

The default network congurations for the c.pHC are:

• unit IP address: 192.168.0.1

• subnet mask: 255.255.255.0

• gateway: 192.168.0.1

Important: in the “capacity extension” function (described in paragraph

6.2.2), DHCP cannot be activated, otherwise the units would not be able to communicate together. DHCP must be disabled on screen Dg05 (as by default).

Important: the controller is not accessible directly via the internet as a rewall guarantees remote access only over a secure connection (Carel tERA cloud connection). Consequently, outside of the local network the controller cannot be accessed, even if the network administrator assigns a public address.

8.1.2 Webserver functions

Once having accessed the webserver, to log in and access the various menu items, use the credentials listed in Table 8.a, according to the type of user.

ID PW Service 77 User 44

Tab. 8.a

Fig. 8.a

To access the web server, to open an internet browser and enter the IP address, followed by /commissioning/index.html (in this case type

10.10.7.198/commissioning/index.html in the browser’s address bar).

IP addresses may be :

• dynamic (if using the DHCP function that automatically assigns an IP

address when a device is connected)

• static (if there is no DHCP function or it cannot be used, with manual

assignment of the IP address directly by the user).

If using a dynamic IP address via the DHCP function on the server, DHCP needs to be enabled on screen Dg05 on the humiFog Direct unit. The IP address shown on the screen will be assigned automatically. The advantage of this feature is that the server and humiFog Direct communicate directly, and there is no need to congure the network parameters (subnet mask and gateway). The disadvantage is that if adding other devices to the same network with humiFog Direct o and not connected, the IP address originally assigned to the unit may change, and therefore the new address needs to be set on screen Dg04 and copied into the browser’s address bar.

Fig. 8.b

Web interface

Once having logged in, the webserver "HOME" page is displayed, also called the web interface. This page displays the main information on the unit, including:

• unit status

• zone request and production

• set point: the value can be set for each zone via webserver

• probes: information on the probe readings and conguration of the

main and limit probe Select the type of signal and dene the minimum and maximum values

• scheduler: enable and set the daily and weekly time bands.

• control: select the type of control, set point, dierential and minimum/

maximum settings

System

The system page shows the main information on the application, the available memory, network and system settings. There is also information for registering the unit on the tERA remote cloud service.

Important: to avoid unwanted modications, some of the main operating and unit parameters can only be set on the web server when the unit is o (o from keypad, settable on the web server).

8.2 Supervisor connection

The supervisor connection uses the serial or Ethernet port (as described in paragraph 4.6). The default communication settings are Modbus on serial port and BACnet on Ethernet port. If connecting to the serial port, enable the chosen protocol (Modbus or BACnet) on the screens. For Modbus protocol only, set the baud rate/ stop bits/parity. The default values (baud rate: 19000 / 2 stop bits / no parity) should work in almost all cases, unless otherwise specied by the supervisor network installer. If connecting via Ethernet, follow the procedure (described in paragraph

8.1.1) to look up the unit’s IP address, then establish whether the communication protocol will be BACnet and/or Modbus.

Important: if using BACnet protocol on a serial port, it cannot be used on the Ethernet port (and vice-versa). The Modbus protocol can on the other hand be used at the same time on both ports.

For all other information, see the manual for the supervisor used and/or contact the supervisor network manager.

9. WIRELESS PROBES, INSTALLATION AND CONFIGURATION

9.1 Type of installation and wireless probe

electrical connections

Wireless probes are available for systems where standard wired probes cannot be used, for example modications to existing installations. An Access Point (CAREL P/N: WS01AB2M20) is used to connect up to four wireless probes. Recommended Carel wireless probes are the room

Fig. 9.a

humiFog Direct/Access point connection:

To connect the humidier to the access point, use the Fieldbus connection on terminal M3 (M3.1: Tx/Rx-, M3.2: Tx/Rx+, M3.3: GND):

Note: the devices have a range of around a hundred metres in a free space, i.e. without any obstacles. In a closed space, the range varies considerably depending on the type of environment and the surrounding objects (shelves, metal partition walls etc.).

If installing multiple wireless probes, the controller will calculate the weighted average between the various probe readings, depending on the settings made by the user and the dened probe groups.

The table below shows the part numbers and descriptions of the Carel devices that can be used:

Tab. 9.a

(WS01G01M00) or industrial versions ( WS01F01M00), both of which measure humidity and temperature. The type of installation is shown in the gure below (referring to four wireless room probes):

Key:

1. humiFog Direct humidier;

2. humidier/access point connection;

3. Access point (WS01AB2M20);

4. Wireless probes for measuring temperature and

humidity (WS01G01M00 or WS01F01M00).

9.2 Wireless probe installation

The main steps for installing the wireless devices are:

• power on the access point (12/24 Vac/dc ±10%m, 100mA) and

complete the initialisation procedure, creating the network and selecting the channel;

• after having opened the domain on the access point, complete the

binding procedure so as to uniquely identify each probe.

The address to be used by the access point is set using the dipswitches on the device, and is the following:

Dipswitch Access

L2L3

DIP:

1 2 3 4

Rx- Rx+ GN D

DIP 1-2-3 selezione indirizzo di rete

+ +G- -

DIP 4 selezione baud di rete

1 2 3 4

OFF ON OFF ON

This assigns the address 2 to the access point, with a baud rate (bit/sec) of 19200 (N82). The addresses of the four serial probes, on the other hand, must be set as shown in the table below:

Address Dipswitch

1 2 3 4 5 6 7 8 Probe 1 16 0 0 0 0 1 0 0 0 Probe 2 17 1 0 0 0 1 0 0 0 Probe 3 18 0 1 0 0 1 0 0 0 Probe 4 19 1 1 0 0 1 0 0 0

Remember to verify the quality of the wireless signal between the Access Point and each wireless probe.

For a complete description of the installation procedure, see the Carel manual on the corresponding probes and access point.

To congure the probes refer to screens: Dc13, Dc14, Dc15, Dc16 and Dc17.

In particular, screen Dc03 is used to enable the wireless probes connected to the access point, knowing that addresses 16, 17, 18 and 19 are probe 1, probe 2, probe 3 and probe 4 respectively.

• there are no short-circuits;

• that room temperature where the cabinet is installed meets specications;

• that the pump shaft is not obstructed;

• that maintenance has been performed on the unit at regular intervals as described in this manual.

The alarm corresponds to the opening of the high pressure switch. Check:

• that the pressure switch is correctly connected to terminals J23-1-J23.2;

• that the pressure switch contact is closed if the pressure is < 90 bars;

• that there are no blockages in the outlet line;

• correct calibration of the mechanical bypass valve on the pump.

If necessary, replace the high pressure switch. The alarm corresponds to a pressure reading by probe RHP > 80 bars (screen C01). Check:

• that probe RHP is correctly connected to terminals J3.3-J3.5 and receives power from J3.1;

• that there are no blockages in the outlet line;

• correct calibration of the mechanical bypass valve on the pump.

If necessary, replace probe RHP. The alarm corresponds to a pressure reading by probe RHP < 20 bars (screen C01). Check:

• that probe RHP is correctly connected to terminals J3.3-J3.5 and receives power from J3.1;

• that there are no leaks in the outlet line;

• correct closing of the drain solenoid valve in zone DR1/DR2 and bypass drain valve BYP (NO valves, 24 Vac to close);

• that lling is enabled for a duration suitable for the length of the water line.

If necessary, replace probe RHP. Possible return of pressurised water through the bypass. Check:

• that the bypass drain solenoid valve BYP is able to drain water;

• correct operation of the mechanical overow valve (opens at 4 bars).

If necessary, replace the bypass drain solenoid valve BYP and/or the overow valve. Possible extended recirculation of water through the bypass. Check:

• that the humidication capacity set on screen Dc18 is equal to the no. of nozzles x capacity of each nozzle;

• that the zone can deliver a ow-rate of water ≥ the minimum ow-rate supplied by the pump;

• that the NTC probe is connected to terminals J5.2-J5.3

• Possible extended water recirculation through the bypass. Check: - that the humidication capacity set on screen Dc18 is equal to the number of nozzles multiplied by the capacity of each nozzle; - that the zone can deliver a water ow-rate ≥ the minimum ow-rate supplied by the pump; - that the NTC probe is connected to terminals J5.2-J5.3

Possible absence of feedwater or low feedwater pressure. Check:

• that there is no alarm on the reverse osmosis system upstream of humiFog Direct

• that there is an expansion vessel or storage vessel with suitably calibrated pump upstream of humiFog Direct.

• operation of the ll solenoid valve.

11. MAINTENANCE

11.1 Routine maintenance

Routine maintenance is recommended every three months, and mainly involves visual inspection of correct operation of the main components.

The following is a list of recommended operations:

• Check water inlet lter.

It is recommended to change the lter cartridge once every 6-12 months. To change the cartridge, switch the unit o and close the feedwater line. Empty the lter using the small tap at the bottom. Unscrew the white holder from the nut at the top using the tool provided. Remove the lter cartridge inside and t a new one (P/N ECKFILT050). Tighten the holder, ensuring that the O-ring is still in good condition to ensure tightness. Close the tap under the holder and open the feedwater line.

• Check pump oil level.

To check the level visually, use a mirror that allows a view of side of the pump facing to the cabinet wall. There is a small mark behind a circular transparent Plexiglas cover. The oil level is correct if, with the unit o, it remains around the central circumference. If the level is lower than the minimum shown in the gure, top up with oil to the correct level (oil P/N 5024646AXX). Generally the oil level should remain constant and periodical top ups should not be needed. If oil leaks are found, contact CAREL.

11.2 Special maintenance

Special maintenance involves all those operations that are performed on a one-o basis in the event of malfunctions or breakages of certain components.

The following components are those susceptible to breakage:

• solenoid valves

• pressure reducer

• pressure switches

• pump motor

• pump

• electronic controller

• fuses

• nozzles

• nozzle manifold

• fans on the blower units

To replace these contact specialist and authorised personnel. To nd the replacement part number, see the paragraph "Cabinet spare parts"

11.3 Pump maintenance

The pump is the most complex mechanical device inside the cabinet, as well as the heart of the high pressure system.It therefore requires regular maintenance, involving the operations described below.

Pump Check/replace monthly every 1000 h

check oil level x check/change oil x check/replace gaskets and valves x

Tab. 11.a

Fig. 11.a

• Check the nozzles: make sure the spray cone from the nozzles is

regular.

Even when using demineralised water, some particle may at times build-up on the nozzle opening, making the spray cone less uniform and aecting absorption eciency. If this happens, remove the nozzle (unscrew using a 10 mm spanner) and clean it (immersing in acetic acid tom remove scale) or replace it (P/N UAKMTP%000). Before assembling the nozzle again, remove the residual Teon from the thread and the small white lter at the base of the nozzle, and apply the sealant again to ensure water tightness.

• Check the fans

Make sure that all of the fans on the blower units are working. In the event of malfunctions, check the power supply wiring. If the wiring is OK, replace the fan.

• Check that there are no water leaks inside cabinet and on the

distribution line and ttings.

11.3.1 Oil change

Important: after the rst 50 hours of operation, the oil in the pump needs to be changed (P/N 5024646AXX). Failure to change the oil after the rst 50 hours may cause damage to the pump and reduce its working life. The rst oil supplied, in fact, will accumulate debris due to transport and commissioning, and a longer operating time cannot be guaranteed.

Important: change the pump oil after the rst 50 hours of operation.

Important: if there are no leaks or faults, when the "1000 h" check

warning is shown, the oil change may be postponed.

In normal operating conditions, except for the rst oil change oil after 50 hours, it is recommended the change the oil every 3000 operating hours. Every 1000 hours, a warning is generated by the electronic controller, while the 3000 operating hours are signalled by the electronic controller via the "3000 hour maintenance" alarm on the display.

To change the oil, follow the sequence described below (with the unit o and the water line closed):

1. Remove the yellow cap on the top of the pump and unscrew the oil

drain plug attraction the bottom (steel hexagonal plug).

2. Empty the oil into a suitable container. Close the plug.

3. Dispose of the oil in accordance with local standards.

4. Fill the pump body with SAE 15W40 mineral oil, up to the level

suggested by the circular marker on the side of the pump (the required oil content is around 350 ml).

5. Finally, close the yellow cap on the top of the pump.

11.3.2 Gasket and valve replacement

The gaskets and valves require replacement every each 3000 hours, as signalled on the display by the “3000 hour maintenance” alarm. Nonetheless, in specic conditions of stress replacement may be needed earlier. Carel recommends to check the pump operation every 1000 operating hours (signalled by notication). If the pump makes noise, or is not able to reach the required operating pressure (70 bars), the gaskets and valves may need to be replaced sooner. Valves and gaskets are consumables, and wear does not reect a product malfunction.

To replace the gaskets, proceed as follows:

1. Disconnect the wiring from the high pressure switch, solenoid valve

BYP and the NTC probe.

2. Disconnect the pump outlet hose (at the top right).

3. Unscrew the eight hex screws that hold the pump head to the guard.

4. Remove the gaskets and replace them with new ones (P/N

UAKVGO1501).

5. Tighten the eight hex screws so as to secure the pump head to the

guard.

6. Connect the outlet hose to the pump.

7. Reconnect the pressure switch, solenoid valve and NTC probe

To replace the valves, proceed as follows:

1. Unscrew the three hexagonal caps on the front of the brass pump

head.

2. Unscrew the three hexagonal caps on the top of the brass pump

head.

3. Replace the six valves with new ones (P/N UAKVGO1501).

4. Tighten the six caps removed previously.

11.6 Blower spare parts

11.4 50 hour oil change warning

The rst “oil change required” maintenance warning is shown after 50 operating hours: this indicates that the oil needs to be changed immediately. This warning is typically displayed a few days after the systems is rst started. Therefore when starting the system, make sure a spare can of oil is available for the rst oil change, in accordance with the procedure described in paragraph “11.3.1 Oil change”. The warning can be easily reset by pressing the “Alarm” button on the user interface (button at the top left).

For practical reasons, the warning can also be reset after 40 operating hours, entering the “control menu > screen Da10”. The warning cannot be reset before 40 operating hours.

11.5 Notiﬁcation, maintenance warning, reset hour counter

After 1000 hours of operation, humiFog direct generates a "1000 hour maintenance" notication, signal only. This is a warning that tells the user to check correct operation of the system. If the pump can reach the nominal operating pressure of 70 bars, no action needs to be taken. The notication can be easily reset by pressing the "alarm" button on the user interface (top left button). The same occurs after 2000 hours of operation.

After 3000 hours, on the other hand, humiFog direct generates a "3000 hour maintenance" alarm, which shuts the unit down. In this case, action needs to be taken on the unit, changing the oil and replacing the pump gaskets and valves (as described in paragraphs 11.3.1 and 11.3.2). Will be necessary subsequently reset the alarm in the menu “Control > screen Da09” and press subsequently the “Alarm” button of the display.
