1- 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
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 mínimum of cable 0,5 mm², the maximum devia-
tion will be of 0,25 ºC (extension cable for probe ref.
AKO-15586
)
NOTE:
Equipment not compatible with
AKO-14917
(external commu-
nication module) and
AKO-14918
