AKO D14412 Temperature Controller Instruction Manual

AKO D14412 Temperature Controller

Warnings

• Using the equipment without following the manufacturer’s instructions may affect the device’s safety requirements. To ensure that the device operates correctly, only probes supplied by AKO should be used.
• The unit must be installed in a location protected from vibrations, water and corrosive gases, where the ambient temperature does not exceed that shown in the technical data.
• To ensure a correct reading, the probe must be situated in a location without any external heat influences except for the temperature that is being measured or controlled.
• The power supply circuit must be provided with a main switch rated at least 2 A, 230 V, located close to the equipment. The cables will enter through the back and should be type H05VV-F or H05V-K.
• The gauge will depend on local regulations, but should in no case 2 be less than 1 mm . 2 -Connecting wires for the relay contacts should be sized 2.5 mm.
• Between -40 ºC and +20 ºC, if the probe NTC is prolonged till 1.000 m with a maximum of cable 0,5 mm², the maximum deviation will be of 0,25 ºC (extension cable for probe ref. AKO-15586)

NOTE: Equipment not compatible with AKO-14917 (external communication module) and AKO-14918 (programming key)

Installation

Wiring

The probe and its cable should NEVER be installed in the same conduit as power, control or supply cables

Operation

ESC key /

• Press for 5 seconds to start/stop Fast Freezing mode (rapid cooling). In the programming menu, exit without saving the parameter, return to the previous level or exit programming.

SET key

• Press for 5 seconds to modify the set point (SP) (Set Point).
• Press for 10 seconds to go to the programming menu. In the programming menu, go to the level displayed or accept the new value while setting a parameter

Up key

Pressing for 5 seconds starts/stops defrosting. The programming menu, allows you to scroll through the various levels or, during the setting of a parameter, to change the value.

Down key

Pressing for 5 seconds activates Standby mode, and pressing for 2 seconds returns the equipment to normal mode. In Standby mode, the equipment performs no actions and only the indicator is displayed on the screen m. The programming menu, allows you to scroll through the various levels or, during the setting of a parameter, to change the value.

Access to set point and programming

Start-up

On power-up, the equipment will start up in Wizard mode (P3 / 1 flashing), press N or Q to select the most appropriate application and press SET.

1. Multipurpose
2. Frozen
3. Fruits and vegetables
4. Fresh fish
5. Soft Drinks
6. Bottle racks
7. AC
8. Heat / Incubators

The wizard will configure the parameters of the equipment for the chosen application (see table “Default settings by application”).

WARNING:

The default parameters by type of application have been defined for the most common applications. Check that these parameters are suitable for your installation.

We reserve the right to supply materials which may be slightly different from those described in our Data Sheets. Updated information on our web site:

Table of parameters and messages

Def. column shows factory-set default parameters. Those marked with * are variable parameters depending on the application chosen in the wizard or the P3 parameter (see table “Default parameters by application”). Unless otherwise stated, temperatures are expressed in °C.

(1): Only available on AKO-D144xx and AKO-D144xx-RC

• D: Displays the message on the display, A: Activates the alarm relay (if available).
• S: Message expressed in the software AKONet
