Warnings
-If the device is used without adhering to the manufacturer's instructions, the device safety require-
ments could be compromised. Only probes supplied by AKO must be used for the unit to operate
correctly.
-From -40 °C to +20 °C, if the NTC sensor is extended to 1000 m with at least a 0.5 mm2 cable, the maximum
deviation will be 0.25 °C (cable for sensor extension ref. AKO-15586. Earth the cable mesh at one end only).
-The product should be installed in a place protected from vibrations, water and corrosive gases, where the
ambient temperature does not exceed the value indicated in the technical data.
-For the reading to be correct, the sensor should be used in a place without heat influences apart from the tem-
perature you want to measure or control.
- The IP65 protection degree is only valid with the protection cover closed.
- The IP65 protection degree is only valid if the cables enter the device using a tube for electric condu
gland with IP65 or above. The gland should be the right size for the diameter of the tube used.
-Do not spray the unit directly with high-pressure hoses, as this could damage it.
IMPORTANT:
- The AUXILIARY relays are programmable, and their operation depends on the configuration.
- The function of the digital inputs depends on the configuration.
- The recommended currents and powers are the maximum working currents and powers.
Maintenance
Clean the surface of the unit with a soft cloth, water and soap.
Do not use abrasive detergents, petrol, alcohol or solvents, as this might damage the unit.
Wiring
Always disconnect the power supply to do the wiring.
The probes and their cables must
NEVER
be installed in a conduit together with power, control or power
supply cables.
For disconnection, the power supply circuit must be equipped with at least a 2 A, 230 V switch, located near the
device. The power supply cable shall be of the H05VV-F or NYM 1x16/3 type. The section to be used will depend
on current local regulations, but should never be less than 1.5 mm
2
.
Cables for relay or contactor outputs should have a section of 2.5 mm
2
, allow working temperatures equal to or
over 70ºC, and be installed with as little bending as possible.
The 120 / 230 V~ wiring area must be kept clear of any other external element.
The wiring setup depends on the options selected in the set-up wizard and on the input and
output configurations (See page 34).
Check the enclosed schematic and the defined configuration before wiring.
IMPORTANT:
• AUXILIARY relays are programmable, and their operation depends on the configuration.
• The function of the digital inputs depends on the configuration.
• The recommended currents and powers are the maximum working currents and powers.
