1INT ODUCTION
1.1 Introduction
EVFTFT219 is a controller with elegant design for the
management of laboratory refrigerated cabinets.
It is available in split version and can be mechanically and
aesthetically integrated into the unit; the user interface
consists of a colour TFT graphic display, touch keys and
guarantees an IP6 protection rating, for easy cleaning.
Access to the controller functions is subject to user
identification; any activity will be tracked and the
temperatures read by the probes will be recorded.
The device is equipped with power failure management
strategies, including a simulation function; thanks to a backup
module and battery, it is possible to guarantee, for as long as
the battery lasts, power to the user interface and the
recording of the temperature value measured by a product
probe that is electrically independent from the cabinet probe.
The device also has a three-point calibration function for the
cabinet probe and the product probe, the "f: time-
temperature" graphic function and a USB communication port
accessible from the front of the user interface (to allow the
upload and the download of the settings and the data recorded
by the controller, through a common USB flash drive).
Installation is by back-panel, with threaded studs and
guarantees flush mounting.

7USE IDENTIFICATION
FUNCTION
7.1 User identification function
The “user identification” function can be enabled/disabled by
parameter ID.
It is possible to set up to 6 user codes and only user 1 (default
code 111) is allowed to set and modify the login credentials of
all other users. If the password of ID1 is forgotten, access to
the device is enabled by code 666.
The controller will require to enter the user identification code
any time one of the following actions is performed:
- turning on/off the device
- editing the working setpoint
- manual defrosting
- accessing parameters
- unlocking the door following an electronic locking
The actions performed will be recorded as special events in the
historical data, with the indication of the user who carried
them out. Each event will cause the sampling of the relevant
temperatures and working setpoint, thus ensuring continuity in
the historical results logging.
An example of how to enter the user code when turning on the
device is given below:
- with the device in stand-by mode, press the key
ON/STAND-BY
- when the user login screen appears, enter the
correct code and press the key SET to confirm and
gain access to the device.
Similarly, the same user identification procedure will be
required to turn off the device.
After the log-in, any action performed within one minute form
the code entering will not require a new authentication.
For the user identification procedure, refer to paragraph
9.2.6.
8BACKUP BATTE Y
8.1 Battery functioning during a
power failure
The controller features a backup battery, which is connected to
EVC99P00 battery-charger. For as long as the battery lasts, it
allows to save data related to the product probes and alarms.
8.2 Battery test management
A simulation of a power failure to the control system is
required to check the battery. To this aim, the “battery test”
output deactivation will cause a power cut-off to the battery-
charger but not to the control module: this allows to regain
the control of the system after 10 seconds by stimulating the
relay.
The buzzer sounds all along the test, which is successful when
the indication “TEST OK” is displayed at the end, meaning that
the power failure has been detected by the digital input and
that the battery power is full, while with low battery the
system is shut down. When restoring the session, the
indication “FAILED” will be displayed to report that the battery
is not working properly. The normal operations will be
recovered only after the key OK is pressed.
Refer to the procedure shown under paragraph Errore.
L'origine riferimento non è stata trovata.. to perform the
