THE BLAST CHILLING MODE

The Blast Chilling function allows you to quick chill food

down to 37°F (3°C), using a probe, in 90 minutes or less,

provided that:

• the total product weight matches the Blast Chiller

Specication

• the initial temperature is lower than or equal to

195°F (90°C)

• the product thickness is less than or equal to 2 inches

(5 cm)

• the food is evenly distributed in the chamber

• a pre-chill initial step is done to improve the chiller

performance in the heaviest conditions

Product temperature before and after a

Chilling Cycle

To comply with HACCP regulation, the target internal

temperature at the end of the cycle is 37°F (3°C) and

cannot be changed. The starting temperature of the food

products can vary depending on the cooking, or nishing,

process which the the food originally went through. For

example, chicken has a higher internal temperature while

pizza dough begins at a lower internal temperature.

Air Temperature

The air temperature is the temperature of the cabinet

where the food is being chilled. The range for a Blast

Chilling process is from -13°F (-25°C) to 48°F (9°C)

degrees and the holding range is from 14°F (-10°C) to

50°F (10°C).

Time or Temperature based Cycles

Use automatic (select food icons) or manual mode to

chill items. Depending on the mode and options selected,

choose to chill items by time, or by using the food probe to

set core temperature.

If time mode is selected, the Blast Chilling cycle terminates

by elapsed time. The product may or may not reach the

desired core temperature.

In food probe mode, the food probe controls the Blast

Chilling and may take more or less time. This time varies

based on the product weight, density, thickness, starting

temperature, etc., to reach the target temperature.

In either mode, after the time has elapsed or the food

probe temperature is reached, the machine switches to

hold mode automatically and maintains the product at the

storage temperature. Determine which mode you prefer,

based on your knowledge of food temperatures and the

time allotment. Select a core temperature-based cycle that

gets the food temperature to match food safety guidelines

at 37°F (3°C), before entering hold mode.

Automatic Defrost

Evaporator defrosts automatically between the chilling and

hold modes, and stops after the ice on the evaporator is

melted.

USER GUIDE

Control Operation

Blast Chilling Cycle Activation

When CHILLING mode is selected, the machine

automatically pre-chills the cabinet to 23°F (-5°C) (see

Figure 2). After reaching the pre-chill temperature, the

manual cycle, or recipe, can be started.

Press the green arrow (Play) to go directly to the recipe

selection screen and skip the pre-chill cycle.

Figure 3: Pre-chilling Screen

Select the appropriate food category or manual cycle.

Figure 4: Food Categories Available

Blast Chilling Automatic OEM Recipes

The pre-programmed recipes do not require cycle setting.

These recipes come with pre-determined settings that give

the best chilling process for the selected type of food (see

Figure 4).

Every recipe has four categories to suit variations of the

selected food.

Figure 5: Meat Chilling Recipe Options

The pre-programmed Meat Recipe categories are set up for

dierent proteins. Press the desired button (buttons on the

left side of the screen), which immediately starts the cycle

(see Figure 5).

The Food Probe Insertion screen appears.

Figure 6: Food Probe Insertion Screen

NOTE: When selecting an automatic recipe, you

must use the food probe.

A time counter runs until the needle probe is inserted

in the food. The electronic system recognizes the probe

insertion and initiates the cycle (see Figure 7).

Figure 7: Cycle Initiated

The Blast Chilling in Progress screen appears. A graph

shows the food core temperatures (from the food probe)

and the air temperature in real time. The right side of the

display shows the food selected, the type of cycle (Chilling

or Freezing icon), and the fan speed. The bottom of the

display shows real time values and cycle setpoint values,

which appear from left to right:

• Food °F – Current core temperature (it takes the

warmest value)

• Air °F – Current air temperature

• Time min. – Elapsed time

• End cycle °F – Food target temperature in an

automatic recipe. When core temperature is reached,

the cycle switches to the next step

USER GUIDE

Control Operation

• Air set °F – Desired air temperature of the current step

• End cycle min. – Time the cycle will end (e.g., three

dashes indicates a core temperature-based cycle, so

time is not available)

• Food scan – Status of the four core temperatures.

The system monitors the four cores of the food thickness

in the rst ve minutes of the cycle. Cores can be excluded

from the algorithm, which means the food measured with

the excluded will not be measured. The warmest core will

determine the end of the total cycle 37°F (3°C). Each core

contributes to regulate the internal cycle’s steps, varying

the air set temperature and fan speed. The following

indicators show core status:

• Blue – Warmest core

• Green – Core is positioned in the food thickness

• Grey – Excluded core

While scanning the food, the cycle runs through four

steps with dierent settings. The goal is to chill the food

in the shortest possible time, while saving the product

integrity. For example, a piece of cooked meat with an

internal temperature of 90°C (194°F) runs through the

initial step at very low temperature. The meat reaches the

highest air temperature at the end to prevent freezer burn.

Conversely, bread is chilled at a warmer air temperature

(above the freezing point) from the start, in order to not

aect the product surface.

NOTE: Automatic OEM recipes are set up in

the factory and guarantee the best

combination of steps for a chilling cycle.

Blast Chilling Manual Program

Press the Manual button on the Food Selection screen (see

Figure 4).

The Manual Program screen appears (see Figure 8). To

set the time, press the TIME button and set the time of

the cycle. Press the AIR TEMPERATURE button to set the

cabinet air temperature. Push the FAN speed button to set

the fan speed—the default is always High or 10. Press the

HOLD TEMPERATURE button to set the temperature at the

end of the cycle. Press OK to start the cycle.

Figure 8: Manual Program Screen

Blast Chilling Custom Recipes

Every food category (icon) allows the creation of four

custom recipes (press the Gear icon on the screen) (see

Figure 5). Custom conguration allows you to choose the

core probe option, the cycle time length (if the core probe

is not selected), the air temperature, the fan speed, and

the air temperature for the holding cycle. To disable or

enable the food probe, press the green check mark or

red X.

(shown in seconds) to insert the probe (see Figure 15).

The system recognizes the probe immediately after it is

inserted, and starts the process.

Figure 15: Blast Chilling Cycle Screen

NOTE: Manual Programs and the Custom Recipes

do not provide the same advantages of the

Automatic OEM Recipes. However, these

programs allow a one single step chilling

process during all the cycle—where air

temperature and fan speed are always the

same value.

Cycle Graph and other functions

For an automatic or manual cycle, the graph shows the

air set temperature, actual air temperature, and set

temperature during a chilling or freezing cycle. The timer

counts up until it reaches the cycle set time or until the

target temperature is reached (when using the insert

probe). After the set time or temperature is reached, the

This Touch Screen Controller can export HACCP information

to a USB key. Press the related button in the USB menu

and the controller will transfer the data to the USB.

The le will be exported as a zipped le named

“haccp.zip”. When you connect the USB to a PC, the le will

appear as a zipped le in a style similar to those seen in

Figure 41)

Figure 41: Dierent Zipped File Icons Displayed

The icon depends on the zip software installed on the PC.

Use any zip software (such as PKZIP, unzip, winrar, G7,

or similar) to extract the le to a folder (see Figure 41).

The folder will be named “haccp” as well. Cycle data is

stored at the following path: haccp\home\root\haccp and

is contained as .csv les (Comma Separated Values) (see

Figure 42). CSV les are associated with Excel:

Figure 42: File Types

Using a Proprietary Software to trace HACCP data

Load and trace the .csv les via a proprietary software

called Blast Chiller Tracer. Your customer service

representative has the following necessary les:

• ICON db (folder)

• lib ICON (folder)

• ICON BlastChillerTracer (Java executable le)

These les can be stored anywhere on your PC, but all les

must stay in the original folder.

NOTE: Do not open db and lib folders. Only run

BlastChillerTracer.

The Tracer is a Java executable le. Java virtual machine

(JVM) is normally preinstalled on a Windows-based OS, to

run games or other graphical interactive application. When

Java is on the PC, the le BlastChillerTracer links to the

program via the JAVA icon automatically. If this does not

happen, install JVM.

Contact your Administrator or install the JVM directly from

the following link: http://www.java.com/it/download/

JVM is safe and free of charge. Once it is installed, run the

executable le BlastChillerTracer—it has a .jar extension.

USER GUIDE

Troubleshooting

WARNING

Before performing any service that involves

electrical disconnection and/or exposure

to electrical components, always follow the

Electrical LOCKOUT/TAGOUT Procedure.

Disconnect all circuits. Failure to comply can

cause property damage, injury, or death.

Perform thorough troubleshooing if the cause of a problem

is not obvious. To test the internal components, unplug or

remove the unit from the power supply.

PROBES

The Blast Chiller is equipped with several temperature

sensing probes. These probes are Negative Temperature

Coecient (NTC) thermoset sensors (see Figure 1 and

Figure 2). The chamber and evaporator probes have the

same conguration. The Touch Screen version has a special

multicore needle probe (5 cores, but only 4 being read from

the board).

NTC Probe Bulb Probe Measuring

Figure 1: Room/Evaporator Probe Type

Figure 2: NTC Needle Probe Types

The needle probe has a dierent sensing element (see

Figure 3). Both types of probes have the same resistance

to temperature correlation.

Figure 3: Pt1000 Needle Probe Types (Multicore)

Checking the Probes

A Probe alarm occurs when something is wrong with the

sensor reading. The problem may be either the sensor

wires or the sensor itself. Probe alarms Er0, Er1, and Er3

are commonly due to an interrupted (open) circuit in the

wires.

Another cause may be a short to the chassis or the two

leads shorting together.

To nd the cause of the alarm, disconnect the indicated

probe and check the resistance between the two wires (or

between any of the 5 wires of a multiprobe type).

If the Ohm reading is 0 Probe circuit is

shorted between

the two wires

Replace the probe

Ohm reading is innity,

∞

Probe is open Replace the probe

Reading matches the

resistance chart at a

known temperature

Probe is good Another problem

is the cause

Reading is not 0 or ∞

and does not match the

resistance chart

Probe is out of

range

Replace the probe

If none of the choices is the issue: Ohm out each wire to

the chassis. If the reading is 0 or less than ∞, the probe is

shorted to the chassis and must be replaced.

NOTE: Use a spare probe instead of the suspected

one. If the alarm continues, the problem is

not the probe.

Search for additional Probe Alarm issues in the probe to

board terminal connection. Check for rust, water, humidity,

loosen/lost connections on the probe terminal block (see

Figure 4).

DOOR SWITCH

The Blast Chiller is equipped with a magnetic sensor. When

the door is closed the sensor is activated by a magnet built

into the door. There are two magnets in each door, one at

the top and one at the bottom. This allows the door to be

reversed (only for non Touch Screen version).

Figure 7: Door Switch

Checking the door switch

If the magnetic sensor is faulty or if the wires are broken or

shorted, the display will show “d-r” continuously. To check

the switch, disconnect the wires from the Main Board at

terminals 48 and 49 (see Figure 7 and Figure 8). Ohm out

the switch between the two wires. Close the switch should

be closed when a magnet is present and open it when it

is not. If the switch tests OK, check for corroded, loose,

or missing connections on the terminals. If no problem is

found in the switch or wires, replace the Main Board.

PRESSURE SWITCH

A pressure-regulating switch is installed to prevent

compressor failures or improper operation due to high

discharge pressure. Self-contained models have a high

pressure switch only, while remote units have a double

switch, like the one shown in Figure 9. In older models

both types of applications had a double switch, triggering

the alarm “hp” for either a low or high pressure event. In

some recent remote applications, the pressure switch is

used for pump down purposes also.

Figure 9: Pressure Switch

Pressure Switch Working Principles – Alarm

Connection

The pressure switch has normally closed contacts that open

if the High or Low pressure limits are exceeded. The switch

is connected to the Main Board at terminals 48 and 50

in case of standard controller (48 is a shared connection

with the door switch), and terminals GND and D1 in the

Touch Screen version. When the pressure switch opens

from either a high or low pressure condition, the display will

show the error code “hP” (or message “HIGH PRESSURE” in

the Touch screen version) (see Figure 10).

Figure 11: Pressure Switch

Current models only have a high pressure switch. After the

pressures return to the normal range, the pressure switch

resets automatically. Current remote applications do not

have an alarm connection with the pressure switch, but

will be used to pump down by low pressure, or to cut out

compressor in case of high pressure (see Figure 10 and

Figure 11).

Pressure Switch Working Principles – Pump Down

Remote applications have a double pressure switch. A

solenoid valve feeds refrigerant to the evaporator. This

valve is closed when setpoint temperature is reached in

the cabinet, allowing the compressor to pump down until

pressure switch trips due to low suction pressure. The

pressure switch will cut out the compressor contactor’s coil

in this case, either for low pressure (pump down) or high

pressure (safety).

NOTE: No high pressure alarm message will

be displayed from the controller if the

remote chillers are working in pump down

conguration.

Pressure Switch Factory Setting

The pressure switch factory settings appear in the following

list:

NOTE: Do not change these settings!

• High pressure limit = 29 barg (425 psig)

• Low pressure limit = 0 barg (0 psig)

• Dierential = 1,2 barg (18 psig)

DOOR FRAME HEATER

Both Shock Freezer and Blast Chiller units come equipped

with a door frame heater to prevent frost build-up on

the door gasket. The heater may be either 115V or 220V

depending on the model/rating. For 220V 3-phase units (or

220V single-phase units with no neutral), the door frame

heater is connected between two live mains. The heater

runs around the frame, under a plastic strip cover (see

Figure 12). Electrical connections run through the lower

cabinet panel to the electrical component box.

Troubleshooting

Depending on the unit’s voltage rating, each load is directly

connected to either L1 or Neutral. L2 is switched by the

dedicated relay.

Checking Relay Outputs

When a component is not running, determine if the related

relay output is working properly. The relays should cut in

and o according to the logic sequences of the controller

(see Figure 13). To check an output, disconnect the input

line to the relay and the output wire (e.g., to check K10,

disconnect both wires on 19 and 20 terminals). Ohm out

the relay terminals and check if the contact is closed when

the relay is activated. Replace the board when a faulty

relay stays open or becomes shorted.

Monitor the communication between the Display and Power

Boards by looking at signals Ext/Int on the bottom left side

of the Display. Both signals blink “Blue” if communication

is good. One or both will blink “Red” if an error is occurs

Figure 23: Ext/Int Indicators

REFRIGERANT PRESSURES CHECKS

High or Low refrigerant pressure levels are dependent on:

• Ambient temperature

• Heat load in the cabinet (Full or Empty)

• Status of the cycle (hot food, frozen food, etc.)

• Cabinet temperature

• TX valve regulation

• Evaporator coil air ow

• Condenser coil air ow

Checking High and Low pressures on the unit cannot

determine if the unit is operating correctly. Careful

analysis, based on the conditions listed, is necessary to

properly diagnose a problem.

For example: Checking the suction pressure results in a

reading of 0.1 barg. This pressure could be correct if the

cabinet temperature is at the minimum (-40°C) and the

evaporator temperature is at -45°C.

If this is not the case, the evaporator may not be getting

sucient refrigerant and the actual evaporator temperature

could be much higher than -45°C. It is not recommended

to base any troubleshooting conclusions solely on the

pressure readings.

SUCTION PRESSURE: 0.1/0.2 barg

Measure this pressure when the cabinet temperature is at

-40°C with the compressor running.

DISCHARGE PRESSURE: 16 barg

This pressure can vary greatly and reach up to 25 barg

psig, depending on the ambient temperature and heat load

inside the cabinet. Very high discharge pressures can cause

the pressure switch to signal an alarm.

HOOK ELECTRICAL POWER TO THE UNIT

The Blast Chiller cabinet requires electrical power for the

evaporator fans (4 or 5 for a single rack model), electronics

controller, feeding valve, frame heater and similar. All the

mentioned components are single phase, therefore the unit

requires only two hot lines (or 1 line and neutral, depending

on the mains voltage). The voltage among lines must be

208V or 220-240V, either 50 or 60 Hz. To hook the power to

the cabinet just open the electrical metal box on the top of

the cabinet and connect L1 and L2 on the power block.

BASIC SERVICE DIAGNOSTIC (TOUCH SCREEN

CONTROLLER)

The Touch Screen Controller displays alarms that identify

the cause of a problem and the components and circuits

involved. In addition, a diagnostic service menu allows

technicians to quickly check the temperature sensors (such

as the needle probe, the chamber probe or the evaporator

probe), the relay status, the door switch input, and many

other things.

Alarm/Failure List

ALARM MESSAGE NOTES/CONSEQUENCES

DOOR The door is open for too long during a

cycle.

MAINTENAINCE Perform a regular service inspection

and preventive maintenance. Call

service for more information.

CONDENSER HIGH

TEMPERATURE

The condenser temperature is too

high if compared to a normal working

condition, dened by a temperature

threshold. For this version of Blast

Chiller, the alarm is not enabled,

because the condenser probe is not

installed.

HIGH PRESSURE Head pressure is too high, exceeding

29 barg (425 psig). Check for a

clogged condenser, condenser

fan motor not running a or pump

down valve not opening when the

compressor is running.

EVAPORATOR LOW

TEMPERATURE

The evaporator temperature is too low

when compared to the current setpoint

temperature. A dierential parameter

LBT states the maximum gap should

exist between setpoint temperature

and evaporator temperature. The alarm

may occur the setpoint temperature

changes during a multistep automatic

recipe, but the evaporator temperature

remains low. Avoid this non-critical

alarm by setting the LBT as high as

possible (i.e., 72°F [40°C]).

ALARM MESSAGE NOTES/CONSEQUENCES

DEFROSTING TIME The defrost process did not stop within

the maximum defrosting time. The

defrost ends by coil temperature (DTE).

If the stop does not happen within DTO

minutes, then the alarm triggers.

Check the evaporator coil icing status;

if one defrost is not enough, repeat

the defrost. If the alarm occurs during

the holding cycle, the problem may be

with the defrost device (hot gas valve).

Using the Blast Chiller as a holding

cabinet for too long may cause this

alarm.

ELECTRICAL

FEEDING

The voltage supply is not within the

safety range. The parameter MRV Main

Reference Voltage determines the

range by plus or minus 20%. Check the

voltage actual reading from the Energy

section during a cycle. Call Service if

low or high voltage is suspected.

LOW

TEMPERATURE

Occurs during the holding cycle, if the

air temperature goes below the lower

temperature limit, parameter ALL.

This parameter is dierential to the

After pressing the PLAY button, below “LOAD U1 ON” will

appear.

The relay #1 (output N‑U1 on the relay board) gets turned

on. After a few seconds, the power board feeds a signal

back to the display to prove that the relay is actually closed

(U1 becomes red and the STATUS will change to ON) (see

Figure 18).

Figure 18: Relay Displayed in Red

Meanwhile the power consumption on that relay output

will appear in the row ENERGY, to monitor if there is any

absorption by the component supplied by relay 1 and how

much the absorption is.

NOTE: When using an additional contactor or

power relay connected on the power

board, the power absorption will not show

the actual power pulled by the electrical

load connected with that contact or power

relay.

Press PLAY button to activate relay #2, or STOP to

de‑activate the relay (see Figure 17). Press the music icon

to test the buzzer.
