AKO-D14730 Universal Controller

Warnings

If the device is used without following the manufacturer’s instructions, it may fail to meet its safety requirements. Only sensors supplied by AKO should be used for the device to operate correctly.
The equipment should be installed in a place that is protected from vibrations, water and corrosive gases, where the ambient temperature does not exceed the value indicated in the technical specifications.
For the reading to be correct, the sensor should be placed somewhere without heat sources other than the temperature to be measured or monitored.
The power circuit should be equipped with a switch for disconnection of at least 2 A, 230 V, situated near the appliance. The cables will be fed in from the rear and will be types H05VV‑F or H05V-K.
The cross-section to be used will depend on current local regulations, but should never be less than 1 mm2.
Cables for relay contact wiring should have a cross-section of 2.5 mm2.
Between -40°C and +20°C, if the NTC sensor is extended to 1000 m with at a cable of least 0.5 mm², the maximum deviation will be 0.25ºC (cable for sensor extension ref. AKO-15586).
ATTENTION : The equipment is not compatible with AKO-14917 (external communication module) and AKO-14918 (programming key).

Description

Universal controller compatible with Pt1000, NTC, PTC, 4-20 mA, 0-10 V and 0.5-4.5 V inputs. It has one relay that can be configured as an alarm or an ON/OFF control. It has one analogue output (4-20 mA, 0-10 V).
The AKO-D14730-C model also has MODBUS communication.

Operation

$AKO-D14730-Universal-Controller-FIG- $3$$

Display, shows the value measured by the probe. During programming: indicates the setting or its value.
Shows the status of relay R1: ON= Activated, OFF= Deactivated.
Shows the status of analogue output R2: ON= Output ≥ 4 mA or 0 V, OFF= Output ≤ 4 mA or 0 V.
ESC key: Deactivates alarms but they remain signalled (according to parameter A16). In the programming menu, it exits the parameter without saving changes, returns to the previous level or exits programming.
N up key: In the programming menu, it allows scrolling through the different levels, or when establishing a setting, changing its value.
Q / m down key: Pressing it for 5 seconds activates stand-by mode, and pressing it for 2 seconds returns the device to normal mode. In stand-by mode, the equipment does not carry out any actions and the display only shows the m indicator. The programming menu allows the user to scroll through the different levels or, when establishing a setting, to change its value.
SET key: Pressing it for 5 seconds allows the user to change the R1 relay setpoint. Pressing it for 10 seconds accesses the programming menu. In the programming menu, the user can access the level shown on the display or, when setting a parameter, accept the new value.
Alarm activated
Stand-by active mode: the rest of the display is switched off.
Programming mode active.

Types of regulation
The type of regulation is set via setting P31.

Relay regulation

Regulation occurs by activating/deactivating relay R1.
Regulation via analogue output R2, relay R1 set as an alarm
Regulation occurs by modulating the analogue output R2. This output must be connected to a variable-frequency drive that controls the compressor. Relay R1 is set as an alarm relay.
Regulation through analogue output R2, relay R1 activates and deactivates the frequency inverter
Regulation occurs by modulating the analogue output R2. This output must be connected to a variable-frequency drive that controls the compressor. Relay R1 controls the activation and deactivation of the variable-frequency drive.

Types of operation
The type of operation is set via setting P0.
