D16323 Large Screen Temperature Controller
Installation Guide
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 which is being measured or controlled.
- The power supply circuit must be provided with a main switch rated at 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 be less than 1 mm².
- Connecting wires for the relay contacts should be sized 2.5 mm².
- Between -40 ºC and +20 ºC, if the probe NTC is prolonged till 1.000 m with a mínimum of cable 0,5² mm, 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. AUX
Operation as per parameter P6
S1: Probe 1, temperature in the chamber or cabinet.
S2: Probe 2, defrost.
DI1/DI2: Digital Input 1 / Digital Input 2
Operation
UP(▲) /SET key
Pressing for 5 seconds activates Standby mode, pressing for 2 seconds
returns the equipment to normal mode. In Standby mode, the equipment performs
no actions and only the AKO indicator is displayed on the screen.
Pressing for 10 seconds goes to the programming menu.
In the programming menu, pressing for 5 seconds goes to the level displayed
or, during the setting of a parameter, accepts the new value.
In programming menu, pressing briefly allows you to scroll through the various
levels or, during the setting of a parameter, to change the value.
DOWN (▼) key
In programming menu, pressing briefly allows you to scroll through the various
levels or, during the setting of a parameter, to change the value.
5- Start-up
On power-up, the equipment will start in Wizard mode (InI / 1 flashing),
select the most appropriate application using the UP / DOWN keys and press SET
- Multipurpose
- Frozen
- Fruits and vegetables
- Fresh fish
- Soft Drinks
- Bottle racks
- AC
The wizard will configure the parameters of the equipment for the chosen
application (see table “Default settings by application”).
Access to set point and Stand-by Programming Menu (parameters)
After 20 seconds with no key being pressed, the equipment will return to the
previous level. If you are on level 3, the changes will not be saved.
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.
