1. INTRODUCTION

Ultracella is a family of products consisting of a control system for the basic functions of a cold room to which can be added further modules for accessory functionalities (e.g. electronic valve, power relays, etc.).

The user interface ensures ease in use and it consists, depending on the models, of:

• wide led display on which can be viewed the operating temperature and the active loads;

• a graphic terminal with text strings in multiple languages, which guide the user during commissioning (wizard). It is also equipped with contextual help menus accessible during programming, that provide an accurate description of the alarms.

The graphic terminal is also available as a “service tool”, which is useful when the control has the only LED interface.

UltraCella has a port for the insertion of a USB memory key to:

• load the languages for the graphic terminal during the ﬁ commissioning;

• parameters upload/download;

• other operations reserved for the service centre (e.g. software update);

• download log of temperature recorded.

When mounting the optional modules are matched to the right of the main control system and connected to it with watertight coupling, to ensure the IP degree of protection of the assembly.

Main characteristics:

•

6 relay outputs: compressor, defrost, fan, light, AUX1, AUX2;

• assembly on guide DIN or wall;

•

LED board with bright display with 3 digits, with decimal point and icons that indicate the operating status;

• integration of the keys in the front panel (LED board) to ensure a high degree of protection (IP65) and safety during operation and cleaning;

• availability of 10 sets of parameters (recipes) preloaded by CAREL but modifi able, corresponding to the same number of parameters confi gurations, to adapt the control to the specifi c conservation needs required by the cold room;

• navigation on intuitive user interface with contextual backlight keyboard;

• defrost can be driven using the keyboard, digital input and supervisor;

• various types of defrost managements, on one or two evaporators: natural (with stop compressor), resistance, hot gas;

• control of compressors with up to 2 Hp or up to 3 Hp with the accessory power module;

• temperature control with virtual adjustment probe;

• digital inputs that can be conﬁ gurated for alarm activation, enabling or activating defrost, door switch, auxiliary output, on / oﬀ , etc;

• control of 1 compressor with double step or of two compressors, even with rotation;

• keyboard safety: operation of the single keys can be disabled to avoid tampering;

• light management by door switch or dedicated key;

• alarm buzzer;

•

HACCP function: temperature monitoring and adjustment in case of alarm due to high temperature during operation or after black out;

•

RS485 network connection for remote monitoring and supervision sytems.

The accessory modules allow:

• the installation of the electronic expansion valve, using the module with CAREL EVD Evolution driver dedicated to the control of superheat;

• compressor control with power relay of up to 3 Hp;

• the use of a single-phase circuit breaker switch in addition to the power relay.

2.9 Installation

Proceed as follows for installation, making reference to the wiring diagrams in the previous paragraphs:

1. Connect the supply and probes: the probes can be remote-controlled up to a maximum distance of 10 metres from the controller as long as cables with minimum section of 1 mm

are used.

2. Program the control: as indicated in chapter “Commissioning” and

“User interface”;

Connect the actuators: the actuators should only be connected after having programmed the controller. It is recommended to carefully evaluate the maximum capacities of the relays indicated in table

“Technical speciﬁ cations”.

Connection to the serial network (if present): all controls are ﬁ tted with a serial connector for connection to the supervisory network.

Warnings: avoid installing UltraCella control system in environments with the following characteristics:

• relative humidity over 90% non-condensing;

• strong vibrations or knocks;

• exposure to continuous jets of water;

• exposure to aggressive and polluting atmospheric agents (e.g.: sulphur and ammonia gases, saline mist, smoke) to avoid corrosion and/or oxidation;

• high magnetic and/or radio frequency interference (e.g. near transmitting antennas);

• exposure of the control system to direct sunlight and atmospheric agents in general.

The following recommendations must be respected when connecting the controllers:

Warnings:

• incorrect connection of the power supply may seriously damage the control system;

• use cable ends that are suitable for the terminals. Loosen every screw and ﬁ t the cable end, next tighten the screws and gently pull the cables to check their tightness. If using an automatic screwdriver, adjust the torque to a value less than 0.5 N · m;

• separate as much as possible (by at least 3 cm) the probe signal and digital input cables from inductive loads and power cables, to avoid any electromagnetic disturbance. Never lay power cables and probe cables in the same cable conduits (including those for the electrical panels). Do not install the probe cables in the immediate vicinity of power devices (contactors, circuit breakers or other). Reduce the length of the sensor cables as much as possible, and avoid spirals around power devices;

• only use IP67 guaranteed probes as end defrost probes; place the probes with the vertical bulb upwards, so as to facilitate drainage of any condensate. Remember that the thermistor temperature probes

(NTC) have no polarity, so the order of connection of terminals is not important.

Caution: in order to ensure the safety of the unit in the event of serious alarms, all the electromechanical safety devices required to guarantee correct operation must be ﬁ tted on the unit.

HACCP - CAUTION

When the temperature measurement is relevant for Food Safety (see

HACCP), will be used only temperature probes suggested by Carel. The standards in force may require the compilation and preservation of appropriate documentation, as well as periodic checks on instrumentation and sensors. If in doubt, consult the person in charge of food safety or the manager of the plant.

of controls connected. The system provides a maximum of 207 units with a maximum length of 1000 m. For the connection it is requested the accessory standard (RS485-USB converter cod. CAREL CVSTDUMOR0) and a terminating resistor of 120 Ω to be placed on the terminals connected to the last control. Connect RS485 converter to the controls as shown in the ﬁ gure. For assigning the serial address see the parameter H0. See the instruction sheet of the converter for further information.

Below are indicated the parameters used to explain the selections for A5 and A9.

1 = Immediate external alarm

Application: external alarm that requires immediate activation (for example, high pressure alarm or compressor thermal overload). The activation of the alarm:

•

shows the message on the display (IA);

• activates the buzzer, if enabled;

• activates the alarm relay, if selected;

2. involves the following actions on the actuators:

• compressor: operates depending on the values assigned to parameter A6 (stop compressor on external alarm).

• fans: continue to operate according to the fan parameters (F).

Note:

• when stopping the compressor, the minimum ON time (c3) is ignored.

• if more than 1 input is conﬁ gured on immediate alarm, the alarm is generated when one of the inputs is opened.

2 = Do not select

3 = Enable defrost

Application: Any defrost request arriving when the contact is open will remain pending until the contact closes.

Close with active when the digital input is opened, the defrost is defrost immediately stopped and the unit restarts normal operation (without performing the dripping or postdripping phases). The LED starts ﬂ ashing to indicate that the defrost request is pending, waiting for the next enabling signal (closing of the contact), when the defrost will be performed completely.

5 = Do not select

6=On/Oﬀ remote

The digital input can also be programmed as a remote ON/OFF switch.

When the control is set to OFF:

• the temperature is displayed alternately with the message “OFF”, the internal timer relative to the parameter dI is updated. If dI expires when the unit is OFF, a defrost is performed when the unit is switched on again;

• the auxiliary relays remain active set as an auxiliary output and light, the other auxiliary outputs are oﬀ ;

• the buzzer and the alarm relay are oﬀ ;

• the control does not perform the control functions, defrosts, continuous cycle, temperature alarm signalling and all the other functions;

• the compressor protection times are respected.

At control restart, all functions are reactivated, except:

• defrost at start-up;

• compressor and fan delay at start-up.

Note: The ON/OFF from external digital input has priority over the keypad and the supervisor.

7 = Do not select

8 = Low pressure switch

By setting A5/A9=8 you can manage the low pressure switch. The low pressure alarm “LP” is signalled when the low pressure switch is triggered:

• during normal regulation, with active compressor and pump down function is disabled (c7=0)

• with pump-down function enabled (c7 >0), if the pump down valve is opened and the compressor is active.

The low pressure alarm signal is delayed by the time set for parameter A7.

The low pressure alarm ‘LP’ stops the compressor.

4 = Start defrost from external contact

Application: this feature is useful in case you need to perform synchronized defrost across multiple units or otherwise manually controlled by an external contact. To perform the defrosts, connect a cyclical, mechanical or electronic timer to the digital input. You can connect multiple units at the same timer and set diﬀ erent values for the parameter d5 (defrost delay from multifunction input) to avoid simultaneous defrosts.

If the door is left open, the signalling control is made via the door switch (if A3=0, digital input DI1, already confi gured as the door switch, is enabled). When the door is open, the evaporator fans are turned off if confi gured at fi xed speed (F0=0,1), otherwise operate at minimum speed defi ned by parameter F7 (if F7<50) if set as variable speed fans

(F0= 2); the compressor continues to operate for the time c12, then turns oﬀ . Once passed the period of time d8d from door opening, compressor and evaporator fans are running again and the error “dor” is displayed.

The pump down has the aim to completely empty the evaporator of the refrigerant at each stop of the compressor. After this phase, you can safely turn oﬀ the compressor, so that the liquid is not present the next time the compressor is started. When the set point is reached, the control closes the pump down valve to stop the ﬂ ow of refrigerant to the evaporator, and, after a certain time, the compressor. In the application diagram there are the pump down valve and the low pressure switch. When the control requires turning on the compressor, if the safety periods c1 and c2 have passed, the pump down valve is opened and after the time set in parameter c8 the compressor is activated.

You can select the pump down:

• on pressure (pressure switch mandatory): once the pump down valve closes, the compressor continues to operate until reaching the low pressure value (contact opened). At this point the compressor is turned oﬀ . If the pressure switch does not change within the time c7, alarm “Pd” triggers, pump down ended due to time-out. The Pd alarm is reset automatically if in the next pump down low pressure is reached within the time c7.

• on time (pressure switch optional): after the valve closes, the compressor operates for the time c7. The ‘Pd’ alarm, Pump down ended by time-out, is deactivated.

6.5 Autostart in pump down

As seen in the previous paragraph, once you reach the set point, the control closes the pump down valve and then the pressure switch changes and signals low pressure. If, due to problems of sealing of the valve, the pressure switch changes again, you can reactivate the compressor with the Auto start function, signalled by the message “Ats”.

To activate the continuous cycle by keyboard see Chapter 3 (parameter value cc> 0). During operation in a continuous cycle, the compressor continues to operate regardless the control, for the time “cc”, to lower the temperature even below the set point. The continuous cycle is stopped after the time cc or when reaching the minimum speciﬁ ed temperature, corresponding to the minimum temperature alarm threshold (AL). If, after the end of the continuous cycle, the temperature falls below the minimum temperature threshold, the low temperature alarm signal can be ignored by suitably setting the c6 parameter: the alarm bypass delay time after continuous cycle.

UltraCella allows you to manage the following types of defrost, depending on parameter d0:

0. electric heater defrost by temperature (placed near the evaporator);

1. hot gas defrost by temperature.

2. electric heater defrost by time;

3. hot gas defrost by time.

Note: Ed1 and Ed2 indicate that the defrost ended due to timeout.

The end of the defrost cycle can be by temperature, and in this case it is necessary to install the defrost probe Sd (to select between B2 and B3) or by time. In the fi rst case the defrost ends if the probe Sd measures a value greater than the value of dt1 or dP1 time has elapsed, in the second case if the defrosting phase exceeds the maximum time dP1. At the end of the defrost the controller can enter in dripping status (present if dd> 0), in which the compressor and the fans are turned off , and subsequently in the state of post-dripping (if present Fd> 0), in which the control resumes with fans off . You can choose the display on the user terminal during defrost, using parameter d6.

The defrost is activated, upon priority:

• from keyboard, using the defrost key;

• from clock, setting the event and the starting mode, with maximum 8 defrosts a day (parameters dd1...dd8);

• setting the cyclic range “dI”;

• from digital input;

• from supervisor.

The defrost is disabled:

• defrost by temperature: when the defrost probe detects a temperature greater than the defrost end temperature dt1;

• defrost by time: in the absence of the defrost probe, the defrost ends after the maximum time set by parameter dP1.

The parameter dI is a security parameter that allows cyclical defrosts every “dI” hours even in the absence of the Real Time Clock (RTC). At the beginning of each defrost cycle, regardless of duration, a count is started.

If the dl time is exceeded without performing any defrost, the defrost is automatically activated. The counter remains active even if the controller is oﬀ .

• d3 determines the time that must elapse, when the defrost is activated, between the stopping of the compressor (electric heater defrost) or the starting of the compressor (hot gas defrost), and the activation of the defrost relays on the main and auxiliary evaporators. In the hot gas gas before activation of the hot gas valve;

• d4 determines whether to activate or not the defrost at the controller start-up. The defrost at start-up request has priority over the activation of the compressor and the continuous cycle. Force a defrost at controller start-up may be useful in special situations.

Example: frequent power drops inside the plant. In case of lack of voltage the tool resets the inner clock that calculates the period of time between two defrosts, starting from zero. If, in an extreme case, the frequency of the power failure were greater than the defrost frequency (e.g. a power failure every 8 hours, against a defrost every 10 hours) the controller would never perform a defrost. In a situation of this type, it is preferable to activate defrost on start-up, above all if the defrost is controlled by temperature (probe on the evaporator), therefore avoiding unnecessary defrosts or at least reducing the running times. In the case of systems with a large number of units, if selecting defrosts at start-up, after a power failure all the units will start defrosting, thus causing a voltage overload.

This can cause power overload. To overcome this, the parameter d5 can be used. It adds a delay before the defrost, and this delay must obviously be diﬀ erent for each unit.

• d5 represents the time that elapses between the start of the controller and the start of the defrost at start-up;

• dd is used to force the stop of the compressor and the evaporator fan after a defrost cycle in order to facilitate the evaporator dripping;

• d8 indicates the time of exclusion of the high temperature alarm signalling from the end of a defrost;

• if dpr = 0, the defrost and the cycle have the same priority; if dpr = 1, if the continuous cycle is in progress and a defrost request intervenes, the continuous cycle ends and the defrost starts.

6.9.1 Fixed speed fans

The status of the fans depends on the compressor status.

When the compressor is:

• on: the fan can also be on (F0=0) or activated based on the evaporator temperature, virtual probe Sv, based on the formula: if Sd ≤ (Sv - F1) -Frd --> FAN = ON if Sd ≥ (Sv - F1) --> FAN = OFF

• oﬀ : the fan is controlled by a PWM that has duty cycle with a ﬁ xed period of 60 minutes.

6.9.2 Variable speed fans

The installation of variable speed fans may be useful to optimise energy consumption. In this case, the fans are powered by the mains, while the control signal is provided by UltraCella by analogue output Y1 0…10 Vdc.

The maximum and minimum fan speed can be set using F6 and F7 parameters (in percentage respect range 0…10V). If using the fan speed controller, F5 represents the temperature below which the fans are activated, with a ﬁ x hysteresis of 1°C.

Note:

• if two evaporator probes are conﬁ gured (Sd1 and Sd2), speed fans is calculated in relation to probe which is measuring higher temperature

(to limit hot air ﬂ ow):

–› regulation on Sd1;

if –› regulation on Sd2.

In case of defrost probe failure, speed fans is ﬁ xed to maximum value deﬁ ned by parameter F6.

•

If F0=2 and HO1=2, speed fan is calculated in according to Figure 6.o.

Anyway, if speed fan is higher than 0, “FAN” relay DO3 is ON anyhow

(closed): if speed fan (Y1) > 0V –› “FAN” relay ON (DO3 closed) if speed fan (Y1) = 0V –› “FAN” relay OFF (DO3 open)

•

If F0=0,1 (ﬁ xed speed fans by “FAN” relay DO3), analogue output is set to 0 (Y1=0V)

•

Inside modulation interval (F1-Frd < Sd < F1), speed fan is modulated in proportional way (e.g. Sd=F1-Frd/2 –› Y1 correspond to (F6+F7)/2 percentage)

Because of mechanical inertia of motor, some EC fans cannot start with a low speed set by parameter F7. To overcome this, fans can be started with maximum speed set by parameter F7 for a “peak time” deﬁ ned by parameter F8, irrespectively of Sd temperature.

On the other hand, if fans operates for too long time at a reduced speed, ice can form on the blades. To avoid this, at interval of F10 minutes, fans are forced to maximum speed for “peak time” deﬁ ned by F8

Note: Cyclic time at maximum speed (determined by both F8 and

F10) is not allowed when door is open.

6.9.3 Evaporator fans during defrost

There is the possibility to force the start of the evaporator fans during control (parameter F2) and during defrost (parameter F3). During the dripping periods (parameter dd > 0) and post-dripping periods

(parameter Fd > 0) the evaporator fans are always oﬀ . This is useful to allow the evaporator to return to normal temperature after defrosting, thus avoiding forcing hot air on evaporator. dd is used to force the stop of the compressor and the evaporator fan after a defrost cycle in order to facilitate evaporator dripping.

6.15 Humidity management

UltraCella can interact with CAREL humidiﬁ cation systems, managing the humidity level in combination with cooling control.

The humidity must be read from UltraCella, conﬁ guring an analogue input (B4 or B5) as a 0 to 10 V or 4 to 20 mA input for humidity probes.

The controller can display the humidity read by the probe and, by suitably conﬁ guring one of the auxiliary outputs, AUX1 or AUX2, activate an external CAREL humidiﬁ er to adjust the humidity level accordingly.

Note: in order to deactivate the buzzer and the relay alarm press the Alarm key

Note: the ﬁ gures refer to the screens on models with single row display, P/Ns WB000S*. In models with two rows, P/Ns WB000D*, the display shows the alarm messages on the second row.

Alarms with automatic reset automatically reset when the cause that generated them, for example, after the replacement of a faulty probe, at the end of the alarm for high temperature, etc. For those with manual reset it is necessary to ﬁ rst remove the cause that generated them, and then press the Alarm button for entire restore.

Example: display and manual restore alarm CHt (condenser high temperature)

Note: the ﬁ gures refer to the screens on models with single row display, P/Ns WB000S*. In models with two rows, P/Ns WB000D*, the display shows the alarm messages on the second row

8.2 Alarms

There are two types of alarms:

• system alarms: e.g. Eeprom alarms, communication (interrupted) alarms, HACCP, high (HI) and low (LO) temperature alarms;

• control alarms: e.g. pump down ended by time-out (Pd), low pressure

(LP).

The alarm for damaged data inside EE/EF memory generates control block. The auxiliary digital outputs AUX1, AUX2 can be conﬁ gured to signal the alarm status, as normally energised or normally de-energised.

See chapter 5. The control indicates the alarms triggered due to faults in the control itself, in the probes or in the network communication. You can also activate an alarm from external contact, immediate type. See chapter

4. On the display the message “IA” appears and at the same time the bell icon blinks and the buzzer activates. If more errors occur, they will appear in sequence on the display.

8.4 HACCP alarms and display

In order to activate monitoring see par 8.6

(HACCP = Hazard Analysis and Critical Control Point).

HACCP can only be activated on the controllers with the RTC option ﬁ tted, and allows control of the operating temperature and the recording of any anomalies due to power failures or increases in the operating temperature due to various causes (breakages, severe operating conditions, operator errors, etc…). There are two types of HACCP events:

•

HA alarms, high temperature during operation;

•

HF alarms, high temperature after power black out.

The alarm causes the blinking of HACCP icon, the display of the relative alarm code on the display, storage of the alarm and activation of the buzzer.

Example: display after HF error and restore of the alarm condition:

8.5 EVD EVO alarms

If an Ultra EVD module, P/N WM00E%, is connected by Fieldbus, UltraCella will be able to signal the following alarms, which only depend on the status of the EVD EVO controller ﬁ tted on the module.

Note: the ﬁ gures refer to the screens on models with single row display, P/Ns WB000S*. In models with two rows, P/Ns WB000D*, the display shows the alarm messages on the second row

Display and cancel HACCP alarms

Access the multifunction menu (see chap. 3) and choose HcP. In the multifunction menu you can see the date and time of the last 3 alarms HA and HF. After entering the multifunction menu (see previous par.), select with UP / DOWN the message “HCP”.

Procedure:

1. Press Set and then UP/DOWN to display the parameters of the following table;

Press Set to display the alarm date and time;

3. Press Prg until you return to standard display.

4. To cancel all HACCP alarms, change the value of the parameter Hcr

Each alarm is displayed with scrolling text, which contains the day of week, hour, minute, and the temperature that caused the alarm. The buﬀ er in which are saved can contain the data of up to 3 alarms. Once full, the new alarm will replace the oldest one. Instead, the alarm counters

(HAn, HFn), after reaching 15, they stop.

Example: HA alarm triggered Thursday at 13:17, with detected temperature of 36.8 °C.

Alarm and activation parameters

AL (AH) allows you to determine the activation temperature for low (high) temperature alarm LO (HI). The set value AL (AH) is always compared with the value detected by the control probe. The parameter Ad represents the alarm activation delay in minutes; the low temperature alarm (LO) activates only if the temperature is lower than threshold AL for period of time greater than Ad. The thresholds can be relative or absolute, depending on the value of parameter A1. In the fi rst case (A1=0) the value AL indicates the deviation regarding the set point and the low temperature alarm activation point is: set point - AL. If the set point diff ers, the activation point will automatically diff er. In the second case

(A1=1), the value AL indicates the low temperature alarm threshold. An active low temperature alarm is indicated via internal buzzer, with the code LO on display and with the activation of the alarm relay. The same occurs for high temperature alarm (HI), considering AH instead of AL.

Notes:

•

The alarm LO and HI are alarms with automatic reset. A0 determines the hysteresis between the value of the activation and deactivation of the alarm;

• if you press the Alarm button when the measurement is above a threshold, the buzzer and the alarm relay immediately turn oﬀ , and an indication of the alarm code will remain active until the measure falls within the activation threshold. Parameter A6 has similar meaning as parameter c4 (duty setting). If an external alarm occurs, the compressor works for a time equal to the value set for parameter A6, while it remains OFF for a ﬁ xed period of 15 minutes.

•

In case of relative alarms (A1= 0) both AL and AH are considered as absolute values (e.g. AL= -10 is considered as AL= 10)

8.8 HACCP Alarm parameters and monitoring activation

In order to activate HACCP alarm monitoring, set parameter HCE=1.

HA alarms

The HA alarm is generated if during normal operation it is noted that the temperature read by the control probe exceeds the high temperature threshold for the time Ad + Htd. Therefore compared to the normal high temperature alarm already signalled by the control, HACCP alarm type HA is delayed by a further Htd time speciﬁ c for HACCP recording.
