Basic configuration

The basic configuration menu allows the equipment to be configured for the most common applications. Press the SET key for 5 seconds to access it. If the access code is activated, a 2-digit code is requested (See page 19), if the code entered is not correct the unit will not enter programming. If a more specific configuration is required use the advanced configuration menu (see page 22) After 20 seconds without touching any key, the unit returns to the previous level without saving changes or it will exit programming.

Function of the keys in programming

SP: Set point
It defines the temperature that should be inside the cold storage room (See page 13):

• Minimum: –45.0 *
• Maximum: 99 *

(Depends on the bottom/top locking of the set point). d0: Defrost frequency
The time that must elapse between the start of each defrost (see page 15)
d1: Maximum defrost duration

The defrost will end after this time has elapsed since it started.
F3: Fan status during defrost

It defines the status of the fans during defrosting. 0= OFF 1= ON
A1: Maximum alarm probe 1

Defines the temperature at which the maximum alarm will be triggered. Only affects probe 1.

• Minimum: –45.0 *
• Maximum: 99 *

(Depends on the bottom/top locking of the set point).
A2: Minimum alarm probe 1
Defines the temperature at which the minimum alarm will be triggered. Only affects probe 1.

• Minimum: –45.0 *
• Maximum: 99 *

Depends on the bottom/top locking of the set point).

Operation

Compressor control

NORMAL OPERATION

CONTINUOUS CYCLE MODE
Use this function to cool the cold rooms before loading products. It is activated by pressing the O key for 5 seconds, the display shows the % icon while this mode is active.

CHANGE OF SET POINT” FUNCTION
Modifies the set point value in the low-use periods of the refrigeration device. If this variation is positive (increases the value), the display will show the ECO icon.

It can be activated after a certain time has elapsed (defined in parameter C11) without activity in the cold room door, to do this one of the digital inputs such as “door contact” (P10 or P11 = 1) must be configured. Optionally, you can activate and deactivate this mode at will, using an external pushbutton (1 press to activate/deactivate), configuring one of the digital inputs as “Change set point” (P10 or P11 = 4).
If we set parameter C11 to 0, it can only be activated by an external pushbutton.

COMPRESSOR PROTECTION DELAY
There are three types of delay, selectable by parameter C4, to protect the compressor. These delays prevent continuous compressor starts and stops due to sudden changes in temperature.
OFF-ON (C4=0): Minimum compressor OFF time before each start-up.
OFF-ON / ON-OFF (C4=1): Minimum time during which the compressor will remain ON and OFF in every cycle. The delay time is defined by parameter C5.

OPERATION IN CASE OF PROBE 1 FAILURE
In the event of probe 1 failure (fault, disconnection, etc.) compressor performance will depend on C6 settings. Users may choose between 3 options:

• C6=0: The compressor will be stopped until probe 1 is working again.
• C6=1: The compressor will be operational until probe 1 is working again.
• C6=2: The compressor will operate according to the average performance of the last 24 hours, taking into account the number of starts and stops and the average time in each state (stop-start).
• C6=3: The compressor will run as scheduled in C7 (ON) and C8 (OFF).

SET POINT LOCKING
Using the C2 and C3 parameters, it is possible to set an upper and a lower limit for the Setpoint (SP), which precludes configuring a set point that is too low or too high that could damage the installation or the stored product.

STOP FANS AND COMPRESSOR WHEN THE DOOR IS OPENED
Parameter P23 defines whether the compressor stops when the cold room door is opened. To do so one of the digital inputs must be configured as “door contact” (P10 or P11=1) (See page 26).
If the door stays open longer than the value programmed in parameter P24, the compressor will return to its normal operation.

Defrost control

Defrost start-up Defrost is initiated if:

• The time scheduled in parameter d0 has passed since the beginning of the last defrost.
• The N key is pressed for 5 seconds.

Defrost type
By resistors: The defrost resistors start-up and the compressor stops; defrost is the result of heat from the resistors. Fans will be running or not depending on parameter F3.

Drip time
Parameter d9 sets drip time and the time added at the end of the defrost cycle to allow for drainage of the remaining water in the evaporator. During this time the compressor and fans will not be running (unless defrost is by air). Defrost termination

The defrost will terminate

• The temperature programmed in parameter d4 has been reached in probe 2 Probe 2 must be activated (P4).
• In the event of probe 2 failure, defrosting will be complete once the maximum time has elapsed (d1)
• The time set in parameter d1 has passed (maximum duration of defrost).
• The H key is pressed for 5 seconds.

Message displayed during defrost
Set by parameter d2, with the choice of showing the actual temperature detected by probe 1 (d2=0), displaying the temperature detected by probe 1 at the start of defrost (d2=1) or displaying the DEF message (d2=2). The d3 parameter defines the time during which the message is displayed, once the drip time (d9) and the fan stop time (F4) is over.

Other parameters
Parameter d5 allows users to specify if the unit will (d5=1) or will not (d5=0) defrost when powered up (initial start-up or after a power failure). In case of choosing option YES (d5=1), the defrost will start after the delay time specified in d6. Using parameter d8, users define the computation of time in d0, choosing between total time elapsed (d8=0) or the total compressor running time (d8=1).NOTE: If parameter d1 is set to 0, no defrost will be performed. Remote defrost This function allows activating the defrost of the unit using an external button, connecting it to one of the digital inputs that must be configured as “remote defrost”(P10 ó P11=6) .

Fan control

• Fans are controlled with probe 2 (evaporator) and parameters F0 (shutdown temperature) and F1 (Probe differential).
• Even if probe 2 is not connected or an error is detected in the probe (E2), the fans will always run regardless of parameters F0 and F1, but taking into account parameters F2 to F5.
• Parameter F2 defines the status of the fans during compressor stops.
• Parameter F3 defines the status of fans during defrost.
• Parameter F4 defines the fan start-up delay after defrosting (see section 9.2)

Light control
Auxiliary relay 3 must be configured as “Light” (P63=1).
Switching the lights on or off is controlled using:

• The ? pushbutton: One press switches the lights on or off.

• The cold room door: When the door is opened, the lights stay on for the time
  defined by parameter P22. If the value is 0, when the door closes the lights go out. (One of the digital inputs must be configured as door contact (P10 or P11=1).

• The control even occurs with the equipment in Stand-by.

Pump down function
This function prevents compressor problems caused by the movement of the refrigerant, using a stop/start technique of the unit controlled by liquid solenoid, the low-pressure switch and the compressor.
For this feature to be active, the auxiliary relay must be set as “Pump down” (P6=1).

SHUTOFF

• When temperature probe 1 reaches the set point value (SP), the AUX 1 relay is deactivated by closing the liquid solenoid.
• Since the compressor is still running the evaporator pressure drops suddenly. When it reaches a specific point, the low-pressure switch is activated, changing the state of digital input 1, and the controller stops the compressor. This maneuver isolates the refrigerant from the compressor crankcase, preventing serious damage on start-up. In case of a low-pressure switch failure, the controller stops the compressor after the safety time set at P15, showing the message “Pd”, but it will continue to function normally. (informative message, does not affect the equipment operation).
• If time P15 is 0 (default value), the compressor will not stop until the low press start is activated, but it will display the “Pd” message after 15 minutes.
• DOES NOT activate the alarm relay or the sound alarm, it is only shown on the display.

STARTUP
When temperature probe 1 reaches the set point value plus the differential (SP+C1), the AUX 1 relay is activated (ON), opening the liquid solenoid. This causes the pressure in the evaporator to increase, disabling the low-pressure switch. The controller detects this change and starts the compressor. If a period of time has elapsed (determined by P14) after the liquid solenoid is opened (AUX 1 relay set to ON), the low press start will not be deactivated, the controller will once again close the solenoid (AUX 1 relay set to OFF) and the “LP” message will be displayed. This maneuver will be repeated every 2 minutes indefinitely until the press start is deactivated and the installation reverts to its normal operation. If time P14 is 0 (default value), the solenoid will stay open until the low press start is deactivated, but it will display the “LP” message after 3 minutes. DOES NOT activate the alarm relay or the sound alarm, it is only shown on the display.

STAND-BY
If the pump-down function is active, some time may elapse from the time the stand-by function starts until the controller stops. This is because certain control phases of the system cannot be stopped.

Alarms
The unit warns the user with a message on the screen of the activation of a relay or the activation of an acoustic signal in certain circumstances, according to the programming of the following parameters.

Max/Min Temperature Alarm

Shows the AH or AL message when the temperature in probe 1 reaches the value set in
the A1 (maximum temperature) or A2 (low temperature) parameters.

This value can be
Absolute (A0=1): A1/A2 should indicate the temperature at which the alarm should be activated.

Relative to SP (A0=0): A1/A2 should indicate the number of degrees above or below the set point at which the alarm is activated. This option allows users to adjust the set point without having to modify the high and low alarm settings. Parameter A10 sets the differentials for both parameters (hysteresis). Activates alarm relay (if P62=1) and sound alarm.

Example
In a controller, we configure the following parameters: SP=2, A1=10, A10=2

• If A0=0 (relative to SP), the maximum temperature alarm goes off when probe 1 reaches 12 degrees and is disabled when it reaches 10 degrees.
• If A0=1 (absolute), the maximum temperature alarm goes off when probe 1 reaches 10 degrees and is disabled when it reaches 8 degrees.

External alarm/severe external alarm

Displays the message AE (external alarm) or AES (severe external alarm), when the digital input configured as an external alarm or severe external alarm is activated. The severe external alarm also deactivates all the charges, therefore, the temperature regulation is stopped. When this alarm disappears the device returns to its normal operation. At least one of the digital inputs must be configured as an external alarm (P10 or P11=2) or severe external alarm (P10 or P11=3). Activates alarm relay (if P62=1) and sound alarm.

Defrost alarm completed by time
Shows the Adt alarm message when a defrost terminates by time-out, if parameter A8=1. DOES NOT activate the alarm relay or the sound alarm, it is only shown on the display.

Door open alarm
Displays the PAb message when the door stays open for a time greater than that set with parameter A12. (One of the digital inputs must be configured as door contact (P10 or P11=1). Activates alarm relay (if P62=1) and sound alarm.

Pump down malfunction error (Stop)

Displays the Pd message if a malfunction is detected when the installation is stopped using the pump down maneuver. (See page 17). DOES NOT activate the alarm relay or the sound alarm, it is only shown on the display.

Pump down malfunction error (Startup)

Displays the LP message if a malfunction is detected when the installation is started up using the pump down maneuver. (See page 17). DOES NOT activate the alarm relay or the sound alarm, it is only shown on the display. Compressor safety chain alarm The ASC message is displayed if any component in the compressor’s safety chain is triggered (compressor motor guard, thermistors or high-pressure controller). Regulation is stopped until protection has been restored.

Alarm delay
These delays prevent the display of specific alarms while allowing the unit to recover normal operation after certain events.

• Start-up delays (A3): Delays activation of temperature alarms on power-up (start-up or after a power failure). This allows for avoiding continuous alarms upon start-up
• Delay after defrost (A4): Delays activation of temperature alarms post-defrost.
• Delay of max/min temperature alarm (A5): Delays activation of maximum (A1) and minimum (A2) temperature alarms from the moment temperature probe 1 reaches the set value.
• Delay of external alarm activation (A6): Delays the activation of the external alarm from the moment the digital input becomes active.
• Delay of external alarm deactivation (A7): Delays the deactivation of the external alarm from the moment the digital input becomes inactive.
• Door opening alarm relay (A12): Delays activation of the open door opening detection alarm.

Alarm relay configuration

• If the auxiliary relay 2 is configured as an alarm relay (P62=1), parameter A9 allows defining the status of the relay when an alarm is triggered.
• A9=0 relay active (ON) in case of alarm (no alarm OFF)
• A9=1 Inactive relay (OFF) in case of alarm (no alarm ON)

Access code (password)
It allows protection the configuration of the unit using a 2-digit code (from 01 to 99). If it is active a code is requested when you try to access the programming menu. This menu cannot be accessed if a wrong value is entered. The code is defined using the L5 parameter. Parameter P2 defines the operation of this code.

Parameter transfer

This function allows transferring the programmed parameters from one device to another, using the AKO-D14918 programming key. This will save a lot of time when configuring similar devices.
Requires the use of the AKO-80018 power supply for the programming key.
Transfer parameters from the equipment to the key

• Disconnect the unit power supply.
• Connect the programming key in the parameter server connector.
• Connect the power supply for the programming key.
• Press the READ key on the programming key.
• Disconnect the device programming key.

Transfer parameters from the key to the equipment

• Disconnect the unit power supply.
• Connect the programming key in the parameter server connector.
• Connect the power supply for the programming key.
• Press the RECORD key for the programming key.
• Disconnect the device programming key.

Connectivity

The unit has a port for RS485 data connection (MODBUS), which can be managed using a PC. Up to 127 units can be connected to a PC with AKONet (AKO-5010), or to the AKO-5011 web server. Each of these units should have a different MODBUS address, that is defined using the P5. Using the AKONet software it is possible to display and capture the data of any connected unit, and configure its parameters.
AKONet: Management software for AKO units with RS485 (MODBUS) communication. If it is installed in a server the software can be accessed from any PC in the network or even from the Internet (it requires the server to have a connection to the Internet and a fixed IP).
AKO-5011: Web server that includes the AKONet software. It can carry out the same functions as the PC, with the advantage of having a server dedicated to communication with the units.
