4.10.1 - TEMPERATURE ALARMS
The temperature alarms work according to the programmed probe
measurement, the type of alarm set in the parameter “A.Ay” the
alarm thresholds set in parameters “A.HA” (maximum alarm) and
“A.LA” (minimum alarm) and the relative differential “A.Ad”.
Through the parameter “A.Ay” it is possible to set if the alarm
thresholds “A.HA” and “A.LA” must be considered as absolute or
relative to the Set Point , if the reference temperature must be Pr1
or “Au” probe measurement and if the display must be show the
messages Hi (maximum alarm)/ Lo (minimum alarm) to the
intervention of the alarms or no.
The possible selections of the parameter “A.Ay” are:
= 1 : Pr1 Absolute Alarms with labels (Hi - Lo)
= 2 : Pr1 Relative Alarms with labels (Hi - Lo)
= 3 : “Au” probe Absolute Alarms with labels (Hi - Lo)
= 4 : “Au” probe Relative Alarms with labels (Hi - Lo)
= 5 : Pr1 Absolute Alarms without labels
= 6 : Pr1 Relative Alarms without labels
= 7 : “Au” probe Absolute Alarms without labels
= 8 : “Au” probe Relative Alarms without labels
Using some parameters it is also possible to delay the
enablement and the intervention of these alarms.
These parameters are:
“A.PA” - is the temperature alarm exclusion time on switching on
the instrument if the instrument is in alarm status when it is
switched on.
If the instrument at power on is not in temperature alarm conditions
the time "A.PA is not considered.
“A.dA” - is the temperature alarm exclusion time at the end of
defrosting (and , if programmed, at the end of draining) and at the
end of a continuous cycle.
“A.At” - is the temperature alarm delay activation time
The temperature alarm is enabled at the end of exclusion time and
is enabled after the “A.At” time when the temperature measured by
the probe exceeds or goes below the respective maximum and
minimum alarm thresholds.
The alarm thresholds will be the same as those set on the
parameters “A.HA” and “A.LA” if the alarms are absolute (“A.Ay”=1,
3, 5, 7).

The maximum and minimum temperature alarms can be disabled
by setting the relative parameters "A.HA" and "A.LA" = oF.
4.10.2 - EXTERNAL ALARM
The instrument can signal an external alarm by activating the digital
input with the function programmed as “i.Fi” = 4 or 5.
At the same time as the signalling of the configured alarm output,
the instrument visualising AL and the variable set in parameter
“i.dS” alternately on the display.
In alarm conditions with “i.Fi”= 5 all the control outputs will be off.
4.10.3 - OPEN DOOR ALARM
The instrument can signal an open door alarm by activating the
digital input with the function programmed as “i.Fi” = 1, 2 or 3.
When the digital input is activated the instrument show oP and
after the delay programmed in parameter “A.oA”, the instrument
signals the alarm via the activation of the configured alarm output
(buzzer/ouput).
At the intervention of the open door alarm the inhibited output will
reactivated (fans or fans + compressor).
4.11 - FUNCTIONING OF KEYS “U” AND “DOWN/AUX”
Two of the instrument keys, in addition to their normal functions,
can be configured to operate other commands.
The U key function can be defined by the parameter “t.UF” while
the DOWN/AUX key function can be defined by the parameter
“t.Fb”
Both the parameters have the same possibilities and can be
configured for the following functions:
=oF - The key carries out no function.
= 1 - Pressing the key for at least 1 second, it is possible to
enable/disable the auxiliary output if configured (“o.Fo”=2).
= 2 - Pressing the key for at least 1 second, it is possible to select
the mode Economic/Normal in rotation. Once selection has been
made, the display will flash the active set point code for about 1
sec. (SP, Eco).
= 3 - Pressing the key for at least 1 second, it is possible to switch
the instrument from the ON status to Stand-by status and vice
versa.
= 4 - Pressing the key for at least 1 sec activates/deactivates a
“Turbo” cycle.
4.12 - PARAMETERS CONFIGURATION BY “A01”
It is possible the transfer from and toward the instrument of the
functioning parameters through the device A01 with 5 poles
connector.
This device A01 it’s mainly useable for the serial programming of
the instruments which need to have the same parameters
configuration or to keep a copy of the programming of an
instrument and allow its rapid retransmission.
The same device can connect the instrument via USB to a PC and
through the proper configuration software tools "TECNOLOGIC
UniversalConf”, it’s possible to configure the operating parameters.
To use the device A01 it’s necessary that the device or instrument
are being supplied.
