AKO PROPlus 3PH BASIC Electronic Panel

Presentation

PROPlus 3PH is the global electronic solution to manage positive and negative cold room stores, in combination with:

• Standard condensing units
• Streamlined condensing units
• Or as a service panel in decentralised systems.

It offers a high degree of IP65 protection for installation in damp environments. It is easy to install thanks to its new connection strip.

Maintenance
Clean the surface of the unit with a soft cloth, water and detergent. Do not use abrasive detergents, petrol, white spirits or solvents.

Precautions
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. Between -40 ºC and +20 ºC, if the NTC probe is extended up to 1,000 m with minimum 0.5 mm² wire, the maximum deviation will be 0.25 ºC (Wire for probe extension ref. AKO-15586).

IMPORTANT:

• The AUX 1, AUX 2 and AUX 3 relays are programmable, and their operation depends on the configuration (see page 25).
• The function of the digital inputs depends on the configuration (See page 26).
• The recommended currents and powers are the maximum working currents and powers.

Recommendations

Disconnect the voltage before carrying out any operations inside the electrical panel. All wiring should be according to current standards and should be carried out by authorised staff. Only carry out the wiring foreseen in the wiring diagrams. Using the electrical panel not observing the manufacturer’s instructions may alter the appliance’s safety requirements. A tool is needed to remove any fixed part.

• Panel installation:
  • It is advisable to leave a clean safety space without obstacles around the panel.
  • Do not knock or make sudden movements on the panel.
  • Carry out the wiring according to the installation manual.
  • The probes and their cables should NEVER be installed in a conduit together with power, control or feeder cables.
  • The earth terminals that the panels contain are installed to guarantee the continuity of earthing, however, earthing is not carried out by the terminal and should be carried out outside the panel.
  • The neutral ratings are of the TT type. The IT rating should not be used.
  • Circuit breakers (protective switches) are of the phase/s + neutral, curve C type, guaranteeing switching and protection against overcurrents.
  • Close the panel when your are not working on it.
  • Residual current protection outside the electrical panel according to low voltage electrotechnical regulations.
  • The panels meet European standard EN 61439-1 / EN 61439-2.
  • Terminals for copper external conductors.
• Checks before starting the panel up:
  • Power supply voltages and frequencies will be the ones that figure in the “Technical specifications” section.
  • Check that there are no loose parts or foreign bodies on connections or switchgear.
  • Check that there is no dust or damp inside the panel.
  • Check the correct fastening of the switchgear and components.
  • Check the correct tightening of the screws and power connections.
  • Check the correct connection of the power conductors.
  • Check the correct insulation of the outer lines and that they do not mechanically force the inner connections of the panel. Check that the maximum current of the Q1 and Q3 current breaker (according to model) has been set correctly. Before starting the  installation up, we recommend preheating the compressor’s housing.
• Checks during the panel start-up:
  • Check that no electric arcs occur.
  • Check that the relays or contactors do not produce ratios.
  • Check that there is no overheating in cables, controllers and the rest of the switchgear.
• Checks after the first 24 hours of operation:
  • Check that no overheating occurs.
  • Retighten screws and power connections.
• Periodical preventive maintenance:
  • The panel should remain closed using its lock.
  • Retighten the power connections once a year.
  • Check the wear of the switchgear once a year.
  • Clean the outer surface of the panel with a soft cloth, water and detergent. Do not use abrasive detergents, petrol, white spirits or solvents.
• Technical data:
  • Working ambient temperature: –5 ºC to 40 ºC
  • Rated isolation voltage Ui = 440 V~
  • Electrical panels with degree of protection: IP 65
  • CEM B environment
  • Terminals for copper conductors
  • Resistance to short-circuits Icc=6 kA
  • Rated pulse voltage (Vimp) 2,5 KV

Description

If pump down is active, it indicates the operation of the compressor.
If pump down is active, it indicates that the solenoid is open, otherwise it indicates that the compressor is in operation.

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, if the code entered is not correct the unit will not enter programming. If more specific configuration is required use the advanced configuration menu (See user manual on www.ako.com) 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:

  • Minimum: –45.0 *
  • Maximum: 99
    (Depends on the bottom/top locking of the set point).

• d0: Defrost frequency
  Time that must elapse between the starting of each defrost.

• 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 defrost. 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).

Connectivity

The unit has a port for RS485 date 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 Internet (it requires the server having connection to Internet and 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.

Parameters

The parameters are grouped into 6 sections depending on their function. Press the keys for 10 seconds to access it. The Def. column shows factory-set default parameters. Temperature values are expressed in ºC. (Equivalent temperature in ºF)
