(19) Manual - Air curtain - SMART
FAILURES AND SOLUTIONS
More than 95% of the complaints are submitted during the start of operation of the equipment and are due to installations
errors.
More than 90% of the failures are solved only by checking the connections. Following the three following points, we
can make sure that the installation is correct:
A) RJ45 cable manipulated: The cable that connects the controller to the air curtains is an 8 lines crossed RJ45 cable.
If manipulated (cut or removed the connector) and incorrectly joined (reverse way) the air curtain will not work
well.
Moreover it can damage the electronics. To solve the problem just turn the connector of the cable (see connection
diagram in the first page).
B) Wrong connection of the RJ45 cable.
Verify whether the connector position is the correct, between the “control” and
“auxiliary”, according to the installation diagram (particularly if there are several air curtains with a single controller).
C) Wrong current supply/input. The air curtain input depends on the type of current available and also on the heating
type of the unit. Connect the unit according to the connection diagrams of the first page.
More common failures and solutions
Effect Problems Solutions
All lights of the
controller are
OFF Is the RJ45 cable the original
(not manipulated), with no
enlargements either
shortenings? Change the cable or connect it again correctly.
Does the current reaches the
connection box? Connect correctly the terminals of the junction box:
Between L and N there must be 230V and if the air curtain goes
with three-phase electrical element, there must be 400V among
terminals L1, L2 and L3.
Is the controller connected to
the air curtain, to the connector
“Control” of the PCBoard?
Connect the cable from the controller to the “Control”, never to
the “Aux”.
Is the fuse of the PCBoard in
good conditions? Check the fuse and replace it in case it is necessary (type T,
slow action).
Some lights of
the controller are
Flashing. The green LED of the
maximum speed flashes when
we stop the air curtain after
having been operating with
heating. It is not a failure, but a safety mechanism. The air curtain turns
on by itself to the maximum speed to get cold and protect its
components. When it decreases from the safety temperature, it
will stop.
Some speed or heating lights
are flashing when the air
curtain is working. It is a protection mechanism of the air curtain so that the internal
parts of the air curtain do not suffer damages.
Situations on which the problem continuously recurs and the way
to solve it:
1. Inlet grille blocked (objects, dirtiness…) the ambient
temperature inside the equipment can increase a lot if the air
cannot circulate. Clean the grille.
2. Small room: we recommend installing a thermostat to control
the heating power so the protection device do not activates.
3. In case that the ambient temperature is already high, we
recommend to lower the power heating or install a thermostat.
4. Inlet air already warm, that comes from another heating
equipment beyond the air curtain. Move the air curtain away,
place a thermostat in the inlet part of the curtain or lower the
heating power.
5. Any motor does not work: call the technical service.
The heating does
not work
Does the three-phase current
reach the connections box? Check installation.
The speed and/or
the heat changes
continuously
with no apparent
reason but the
lights of the
controller are not
flashing. Probably the RJ45 cable is
near interference sources,
transmitters, cable plates,
particularly those that supply
current to Motors, etc. Pass the cable the furthest possible away from interference
sources, particularly when long distances or use a screened
table.
