7 FUNCTIONS WITH FACILITATED ACCESS
7.1 Register of minimum and maximum temperatures
Press , appear the minimum registered temperatures. Soon will apears the the maximum registered
temperature.
Note:
To reset the registers, keep the key pressed during the visualization of minimum and maximum
registers until to be showed.

7.2 Viewing current date and time:
You can press the key shortly to view the date and time set in the controller. The display
shows the current day, month, year, hours and minutes, in this order.
Ex: 03/17/2006 12h43min
F22 - Delay to enable the alarm when the instrument is powered on
During this time the alarm is kept turned off waiting that the system reaches the working control
temperature (only if F17= 4,5 or 6).
F23 -Reactivation time of alarm when inhibited manually
This function allows three different settings (only if F17= 4,5 or 6):
-
The alarm is inhibited by an indefinite period or until the temperature range in normal
working condition and return the alarm again;
-
The alarm can not be inhibited by facilitating access keys;
to
-
The alarm will be inhibited during this period (in minutes), returning the call if the
alarm condition persists;
F24 - Alarm time (on cycle)
It allows to adust the time that OUT3 output will keep turned on (only if F17= 4,5 or 6).
F25 - Alarm time (off cycle)
It allows to adust the time that OUT3 output will keep turned off (only if F17= 4,5 or 6).
F26 - Enables
F24 and F25
on
easy access
menu
Enables the time setting alarm ON and OFF in the easy access
menu, if the 3rd stage is configured as an
alarm (F17=4, 5 or 6).
- Disabled
- Enabled
F27 -Operation mode of Buzzer
- Intra-range alarm (F28 and F29)
- Extra-range alarm (F28 and F29)
- Extra-range alarm relative to the 1st stage setpoint ( - F28 and + F29), It is
considered the absolute values of F28 and F29)
F28 - Acting point of Buzzer (inferior limit)
It is the inferior value of temperature to the buzzer alarm act as the configured Operation Mode of Buzzer
(F27).
F29 - Acting point of Buzzer (superior limit)
It is the superior value of temperature to the buzzer alarm act as the configured Operation Mode of
Buzzer (F27).
F30 - Buzzer time on
It is the time that the Buzzer will be turned on (cycle on). To turn it off the sonore alarm (Buzzer) adjust the
value “0” to this function.
F31 - Buzzer time off
It is the time that the buzzer will be turned off (cycle off). To turn it off the sonore alarm (Buzzer) adjust the
value “0” to this function.
F32 - Inhibition time of Buzzer during electrical supply
It is the time were the alarm will kept turned off even if in alarm contitions.
It serves to inhibit the buzzer during the time while the system do not reaches the working control
temperature.
F33 -Reactivation time of Buzzer when inhibited manually
This function allows three different settings:
-
The Buzzer is inhibited by an indefinite period or until the temperature range in normal
working condition and return the alarm again;
-
The Buzzer can not be inhibited by facilitating access keys;
to
The Buzzer will be inhibited during this period (in minutes), returning the call if the
alarm condition persists
.
-
F34 - Time for the open door alarm
When the door open alarm is enabled, the buzzer will be triggered after the door has been left open for
the programmed amount of time. The time the buzzer is on and off is set with F30 and F31.
- Disabled
to
- Minutes to activate the open door alarm
F35 - Digital input operation mode
This function allows to configure what status of digital input will indicate that the door is open:
- Closed contact indicates that the door is open
- Open contact indicates that the door is open
F36 - Datalogger operation mode
Allows to choose between the following operation modes of the datalogger:
- Always OFF
- Always ON
- Manual operation
F37 - Datalogger sampling interval
Time period in which the controller will register a sample of the temperature and the control outputs
status.
F38 - Variation of the temperature to force data recording
Temperature difference to forces the recording of data in the memory, independently of the sampling
time configured at F37. To desable this function, just decrease the value until the message
appears in the display.
F39 - Variation of the outputs to force data recording
Indicates whether the change in the control outputs (configured as cooling or heating) will force the
recording of data in memory regardless of the time of sampling set in F37. Data recording will also occur
if the device enters or exits the alarm condition (for OUT3 and buzzer) and lack of and return electricity
(if the battery is connected as described on item 10.1)
- OFF
- ON
F40 - Overwrite records in the memory when it is full
This function indicates whether the controller should start writing the new data at the beginning of the
datalogger's memory when it is full. This prevents that the latest data recorded from controller be erased
first.
F41 - Intensity of the digital filter
This filter aims at simulating an increase of the mass of sensor , thus increasing its response time
(thermal inertia). The larger the value adjusted in this function, the longest the response time of sensor.
A typical application requiring this filter is the freezer for ice cream or frozen goods, because when the
door is opened a hot air mass reaches the sensor directly, causing the indication of the measured
temperature to rise quickly and the compressor to be activated unnecessarily.
F42 - Network address RS - 485
Each controller connected to the RS-485 network must have its own address different from the others so
that the computer will be able to identify it.
Attention:
To avoid communication problems, make sure that there are no controllers with the same
address.
