or
9
is activated.
Simultaneously to the configured alarm signal (buzzer and/
or output), the instrument points out the alarm lighting up the
LED and displaying the label
AL
alternated to the variable
set at parameter
i.dS
.

the control outputs are disabled at digital
input intervention.
5.10.3 Open Door Alarm

.
At the intervention of the open door alarm the inhibited output
are immediately reactivated (fans or fans + compressor).

6 ACCESSORIES
The instrument is equipped with a connector that allows the
connection to some accessories.
6.1 Parameters Configuration by A01
The instrument is equipped with a 5 poles connector that
allows the transfer from and toward the instrument of the
functioning parameters through the device
A01
.
This device it is mainly usable for serial programming those
instruments that need the same parameters configuration or
to keep a copy of the parameters setting of an instrument and
allow its fast duplication.
The same device allows to connect a PC via USB with which,
through the appropriate configuration software for “
AT Univer-
salConf tools
”, the operating parameters can be configured.
To use the
A01
device it is necessary that the device or instru-
ment are being correctly supplied.
