5 USER INTERFACE

5.1 Preliminary notes

The following operating status exist:

- the “stand-by” status (the device is powered and is off)

- the “on” status (the device is powered, is on and is in stand-by for the start-up of an operating cycle)

- the “run” status (the device is powered, is on and an operating cycle is in progress).

Hereon, the term "device switch-on" means the passage from the "stand-by" status to the "on" status. the term "switch-

off" means passage from the "on" status to the "stand-by" status.

If a power cut occurs during the "stand-by" status or during the "on" status, the device will re-propose the same status

when the power supply is restored.

If a power cut occurs during the "run" status, the device will operate as follows when this is restored:

operation after cut-off of the power supply depends on parameter "P6"; if set at 0 the cycle will be interrupted, if set at 1

the cycle will be re-started and if set at 2 the cycle will only be re-started if the the power cut-off supply was less than the

time set by parameter "P5".

5.2 Device commissioning

Operate as follows:

1. Connect the device power supply. if parameter E9 is set at 1, the device will display the EVCO splash screen for 10

seconds, otherwise it will display a black screen for 10 seconds, after which it will go to the STANDBY status.

Page 15 of 62

EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224

2. Press and release the ON/STAND-BY (1) key.

If the duration of power supply cut-off was such to cause the clock error, the board will display the clock setting

screen directly. The controller does not control the coherence of the data entered, it is the user's job to control

the data are entered correctly.

5.3 Switching the Device On/Off

Operate as follows:

1. Press and release the ON/STAND-BY key.

5.4 The display

The display will be off during the STANDBY status. The LEDs relative to the active keys are on.

During the ON status, the device will display the date, real time, cabinet temperature and the possible functions that can

be selected.

CYCLE END

MACHINE STOP

6. OPERATION

6.1 Preliminary notes

The controller supplies a complete control for retarder-proofer cabinets or cells for confectionery and bread-making,

through the automatic management of the complete mixture retarder-proofer cycle.

MACHINE

START

An automatic retarder-proffer cycle is composed of 5 different phases with different temperatures, relative humidity, fan

speed and duration, which are performed one after the other and precisely:

1. BLOCK phase

The block phase is the first phase of the automatic cycle.

Temperature regulation is active and is neutral area, the temperature set-point, the humidity set-point (the control if

envisioned), the speed of the fans and the duration in hours and minutes of the phase are established by the final user.

Adjustment of the relative humidity depends on parameter rU4. If set at zero, humidity control is not envisioned in this

phase.

2. STORAGE phase

The storage phase is the second phase of the automatic cycle.

Temperature regulation is active and is neutral area, the temperature set-point, the humidity set-point (the control if

envisioned), the speed of the fans and are established by the final user.

Adjustment of the relative humidity depends on parameter rU4. If set at zero, humidity control is not envisioned in this

phase.

The duration of this phase is calculated automatically by the controller on the basis of the duration of the lock, recovery,

proving phases and the day and time of proving end time desired for the mixture.

3. RECOVERY phase

The recovery phase is the third phase of the automatic cycle.

The temperature regulation is active and is NEUTRAL AREA, the work set-point is established by the final user. The

passage from the storage set-point (previous phase) to the recovery set-point can be gradual with increase percentages

established in the parameters programming phase.

The relative humidity regulation is active and is NEUTRAL AREA, the work set-point is established by the final user.

The duration in hours and minutes of the phase and the evaporator fan speed are established by the final user.

Page 17 of 62

EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224

4. PROVING phase

The proving phase is the fourth phase of the automatic cycle.

The temperature regulation is active and is NEUTRAL AREA, the work set-point is established by the final user. The

passage from the recovery set-point (previous phase) to the proving set-point can be gradual with increase percentages

established in the parameters programming phase.

The relative humidity regulation is active and is NEUTRAL AREA, the work set-point is established by the final user.

The duration in hours and minutes of the phase and the evaporator fan speed are established by the final user.

5. BAKING DELAY phase

The baking delay phase is the fifth phase of the automatic cycle.

The baking delay phase is always disabled but can be enabled both in the cycle setting phase and also with cycle in

progress by the final user.

The temperature regulation is active and is NEUTRAL AREA, the work set-point is established by the final user.

The relative humidity regulation is active and is NEUTRAL AREA, the work set-point is established by the final user, as is

the evaporator fan speed.

The duration of the phase is theoretically infinite, i.e. it ends when the cycle is interrupted by pressing the stop key for 3

seconds.

There are also 2 manual work cycles available; one MANUAL REFRIGERATION cycle (equivalent to a storage but with

infinite duration) and a MANUAL HEATING cycle (equivalent to a proving cycle with infinite duration and without regulation

steps).

To make these regulations possible, the controller will therefore manage the utilities set-up for cooling (compressor,

evaporator fan, defrosting, pump-down electrovalve), for heating (heating elements or operating in heat pump mode),

humidification (steam generator, humidifier) end dehumidification (dehumidification via extraction fan or via activation of

the cooling plant); the regulations of each individual utility will be described in the following chapters.

In addition to management of the automatic and manual cycles, the controller envisions the possibility to manage other

functions, such as:

- Pre-cooling management

- "Delayed baking" connection/disconnection management

- Cabinet light management

- Management of 10 user programs

- Management of 10 Favourite Programs

- Connection to RICS

- Host USB port management on machine for: download/upload PROGRAMS, download/upload PARAMETERS and

download HACCP data.

9 Regulations

9.1 Pre-cooling

The pre-cooling cycle has the purpose of taking the cabinet to a determined temperature before selecting and performing

a retarder-proofer cycle.

During the pre-cooling cycle, the compressor, condenser fans, the pump-down electrovalve (if enabled) and the

evaporator fan work to reach the temperature established.

Once the pre-cooling temperature has been reached, the buzzer rings intermittently to indicate that the machine is ready

to perform a cycle. The buzzer is silenced by pressing any key or after the time defined by parameter E11.

The pre-cooling cycle continues until the START/STOP key is pressed or until an automatic or manual cycle is started by

the user.

9.2 Temperature regulation

The temperature regulation for all machine phases is with neutral area.

Meaning with a work set-point and a neutral area within which activations of loads set-up for heating or cooling do not

take place.

When the temperature goes above the neutral area value of the cooling differential value, the utilities set-up for cooling

will be activated until the temperature returns within the neutral area value.

In the same way, when the temperature goes below the neutral area value of the heating differential value, the utilities

set-up for heating will be activated until the temperature returns within the neutral area value.

9.2.1 Generating cold

The generation of the cold refers to the cooling circuit installed on the machine.

During a cooling request, the compressor output will be activated along with the pump-down electro valve (if enabled).

The evaporator fan will go in continuous mode or parallel to the compressor on the basis of that established for each

parameters configuration phase and at the speed established for the phase in progress.

9.2.2 Generating heat

Generation of the heat refers to a heating element.

During a heating request, the heating element outputs will be activated, with possibility of management of a switch-on

and switch-off duty cycle, defined by parameters rH6 and rH7 in a way to limit the heating power if very powerful resistors

are used, in order to prevent overheating in the cabinet.

The evaporator fan will go continuously or in parallel to the resistors output, at the speed established for the phase in

progress.

9.3 Regulation of humidity

The regulation of the humidity in the cabinet for all phases where it is envisioned and with humidity transducer enabled, is

neutral area.

Meaning with a work set-point and a neutral area within which activations of loads set-up for humidification or

dehumidification do not take place.

When the humidity goes above the neutral area value of the dehumidification differential value, the utilities set-up for

dehumidification will be activated until the humidity returns within the neutral area value.

In the same way, when the humidity goes below the neutral area value of the humidification differential value, the utilities

set-up for humidification will be activated proportionally until the humidity returns within the neutral area value. (For

management without humidity transducer, see chapter 0).

9.3.1 Humidification management

Generation of humidity refers to two different utilities, a humidity generator output and a humidifier output.

The humidity generator output is activated during the phases in which management of humidification is envisioned; it is

used for machines with external boiler, in order to generate the steam to be introduced successively into the cabinet

whenever requested by the regulator.

The humidifier output activates when the humidity value inside the cabinet drops below the neutral area value given by

the parameter rU9 of the humidification differential value given by the parameter rU8. The percentage activation of the

humidifier output will be proportional to the value of the humidity with respect to the humidification proportional band

defined by the parameter rU10. The humidification activation/deactivation cycle time is given by parameter ru11 and

regulated on the basis of times defined by parameter rU12.

9.3.2 Dehumidification management

Dehumidification can be managed in two different ways, via an extraction/dehumidifier fan (u3=1) or via the activation of

the cooling plant (u3=1).

In the case of management via extractor fan/dehumidifier, the output will activate when the humidity has exceeded the

dehumidification neutral area, given by parameter rU6 of the value of the differential value given by the parameter rU5

and deactivates when the humidity has returned within the dehumidification neutral area value.

The compressor will behave in the same way whenever the management of the pump-down electrovalve is enabled

(parameter u1 =1).

If pump-down electrovalve management is enabled (parameter u1=0), there will first be a dehumidification attempt via

activation of the electrovalve for a period of time equal to parameter rU7, to try and make use of the high pressure

generated during pump-down in compressor switch-off, on the expiry of which, the compressor output will be activated, if

dehumidification is still requested.

Once the humidity returns within the dehumidification neutral area value, the pump-down electrovalve will be deactivated.

After which, the compressor will deactivate via the pump-down algorithm.

10 Loads management

10.1 Management of the compressor

Compressor activation is subject to the delay time between the two switch-ons (parameter C1), the delay between switch-

off and successive activation (parameter C2), the activation delay from board power on (parameter C0) and the minimum

switch-on time (parameter C3).

The compressor can also be active during hot gas defrosting (parameter d1 = 1). In this case, for the defrosting to start,

the compressor must be active for at least the time established with parameter d15.

The compressor can also be used for dehumidification; for more details see paragraph 0.

Compressor switch-off is managed differently when management of the pump-down electrovalve management is

envisioned. For greater details see the staff 0.

10.2 Pump-down management

If output K8 is configured as pump-down electrovalve (parameter u1= 0), the controller will manage the interaction

between compressor output and electrovalve output as follows:

With timed pump-down (parameter u1 = 0 and i6 = 0 or 1):

On activation of the compressor in parallel, the pump-down electrovalve will also be activated.

Compressor deactivation will be advanced by the deactivation of the pump-down electrovalve; after time u2 the

compressor outlet will also be deactivated.

Page 31 of 62

EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224

With pump-down managed from LP digital input (parameter u1 = 0 and i6 = 2):

On activation of the compressor in parallel, the pump-down electrovalve will also be activated.

Compressor deactivation will be advanced by the deactivation of the pump-down electrovalve; the compressor will be

switched off successively via the intervention of the LP digital input.

Whenever the LP digital input does not intervene within maximum time U2, the compressor will be deactivated and the PD

alarm activated; an alarm turns off the high-pressure compressor regardless of the management of the pump-down.

If the pump-down is managed by the LP digital input, at every compressor output and electrovalve switch-on, a LP digital

input rearm time will be loaded (parameter i9). When the compressor is off, the status of the LP digital input will not be

considered.

10.3 Management of the evaporator fan

The evaporator fan is managed via the PWM analogue output and the phase cut module EVDFAN1 or via the digital output

K8 in On/Off mode if the parameter u1 = 1.

The evaporator fan can be configured for every phase of the cycle to operate continuously or in parallel to the adjustment

output, i.e. in parallel with the compressor, heating element, humidification and dehumidification. The definition of the

behaviour is given by the parameters from F0 to F4.

It will also be possible to establish a delay time for deactivation of the fan with respect to the adjustment output through

parameter F13 and a duty-cycle with a cycle time and an On time given by parameters F14 and F 15 during deactivation

of the main utility. If parameters F14 and F15 are at zero, there will be no activation.

In the event of evaporator fan management via PWM analogue output, it will also be possible to establish the speed of the

fan itself for every phase.

O fan switch-on the controller manages a speed (F21) and a peak time (F22) of the same. On conclusion of the ramp-up

phase, the fan will modulate according to the speed set for the phase in progress, compensated via parameters F23 and

F24, which respectively establish the minimum and maximum speed of the fan itself.

The fan is OFF during defrosting cycle. At the end of a defrosting cycle the evaporator fan will remain at a standstill for the

dripping time given by parameter d7 and for the successive evaporator fans standstill time given by parameter F12.

Evaporator fan calibration procedure managed via TDF module:

To adapt the TDF adjustment to all types of single-phase 230 Vac motors, it is recommended to perform manually

calibrate the evaporator fan.

1. Set F23 at 0% and F24 at 100%

2. Carry out a manual cycle and varying the fan speed, check the minimum percentage below which the fan

switches off and the maximum percentage above which the fan goes to maximum.

3. Set these values respectively for F23 and F24.

10.4 Defrosting management

Defrosting is active during the automatic LOCK and STORAGE phases and during the MANUAL COOLING phase and can be

automatic (at time intervals) or manual. Manual defrosting can be activated from the PRE-SELECTION, MANUAL CYCLE

RUN OPTIONS and AUTOMATIC CYCLE RUN OPTIONS menu.

Depending on the value of parameter d1, the machine will perform electric or hot gas defrosting cycles.

Defrosting will end on reaching the defrosting end temperature given by the parameter d2, if the evaporator probe is

enabled (parameter P3=1) or for maximum duration given by parameter d3. If the evaporator probe is enabled but

broken, defrosting ends due to maximum duration.

At the end of defrosting, the controller will perform a dripping time (d7) during which, all adjustment outputs will be

switched off. After dripping time, the cooling plant will start to operate again but the activation of the evaporator fan will

be delayed further by the time given by the parameter F12.

In the event of hot gas defrosting, the compressor must be activated for at least time d15 for the compressor to start.

Page 32 of 62

EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224

10.5 Management of the heating elements

During a heating request, the heating elements output will be activated, making the management of a switch-on/off duty-

cycle also possible, defined by parameters rH6 and rH7.

10.5.1 Cabinet step heating management

The desired set-point can be reached in the recovery and proving phases gradually, defining the number of steps to reach

the set-point and the percentage increase of the set-point for every step fixed.

For the recovery phase, the number of steps is defined by parameter rr0, while the percentage increases of the set-point

are given by parameters from rr1 to rr10.

For the proving phase, the number of steps is defined by parameter rL0, while the percentage increases of the set-point

are given by parameters from rrL1 to rL10.

Attention, it is the user's task to check the coherence of the number of steps set and the correct number of set-point

increase percentages. Example, if rr0 is equal to 4, only the parameters from rr1 to rr4 must be set.

10.6 Management of the steam generator

The steam generator output is active during all phases in which cabinet humidification management is envisioned.

10.7 Humidification management

The humidity in the cabinet can be managed with or without the use of humidity transducer, depending on the value of the

parameter rU0.

10.7.1 Management of humidity without transducer (rU0 = 1)

In this case, the humidifier output will remain active for a variable duty-cycle according to the humidity set-point set for

the phase in progress.

The duration of the activations and deactivations of the output is given by parameters rU2 (humidification cycle time) and

the maximum humidification time to obtain 100% humidity inside the cabinet (rU3).

The activation times will therefore be a percentage of the parameter rU3, on the basis of the set-point set, which will

repeat every cycle time set with rU2.

10.7.2 Management of humidity with transducer (rU0 = 0)

The humidifier output activates when the humidity value inside the cabinet drops below the neutral area value (rU9) of the

humidification differential value (rU8). The activation percentage of the humidifier output will be proportional to the value

of the humidity with respect to the humidification proportional band value (rU10), on the basis of the humidification cycle

time (rU11) and a times base for said time (rU12).

Page 33 of 62

EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224

10.8 Dehumidification management

Dehumidification management is only active when the humidity management takes place via the use of the humidity

transducer (rU0 = 0).

The dehumidification can be managed in two different ways: via an extractor fan (parameter u3 = 0, utility associated to

output K4) or via the activation of the cooling plant (compressor and pump-down electrovalve if present).

10.8.1 Management via extractor fan/dehumidifier

In the case of management via extractor fan/dehumidifier, the output will activate when the humidity has exceeded the

dehumidification neutral area, (rU6) of the value of the differential value (rU5) and deactivates when the humidity has

returned within the dehumidification neutral area value.

10.8.2 Management via cooling plant activation

The compressor will behave in the same way whenever the management of the pump-down electrovalve is enabled.

If, instead, pump-down electrovalve management is enabled, there will first be a dehumidification attempt via activation

of the electrovalve (rU7, to try and make use of the high pressure generated during pump-down in compressor switch-off

mode), on the expiry of which, the compressor output will be activated.

Once the humidity returns within the dehumidification neutral area value, the pump-down electrovalve will be deactivated.

After which, the compressor will deactivate via the pump-down algorithm.

10.9 Management of the condenser fan

If parameter u3 has value 1, output K4 will assume condenser fan control function.

If the condenser probe is active (parameter P4 = 1), the condenser fan will activate when the condenser temperature is

over the value of parameter F16 of the differential value (F16 + 2.0 °C / 4 °F), independently from the status of the

compressor, while it will always be on with the compressor on.

The condenser fan will switch-off when the condenser temperature drops below the value of parameter F16.

With condenser probe disabled (parameter P4 = 0) the condenser fan will be activated in parallel to the compressor, while

deactivation will be delayed by the time established with parameter F17.

The condenser fan is always on during an overheated condenser alarm (label COH) or compressor blocked (label CSd)

alarm.

The fans are handled during the hot gas defrost.

10.10 Cabinet light management

Cabinet light switch-on is enabled/disabled by opening/closing the door.

Light on with door open, light off with door closed.
