View procedure
• Move the local selector to OFF and then
simultaneously press OPEN and STOP within
20 sec (see chapter ‘Local controls, entering
view and set-up mode). Select the language
according to the instructions (see ‘Entering
the view mode’). When the message displayed
is ‘VIEW MODE OK?’ press YES. Press NO to
scroll through the list of available menus and
press YES to select the Maintenance menu.
• Press NO to scroll through the list of
available routines and press YES to select
themaintenance date routine.

14.4.6 Data logger
The ‘data logger’ routine allows the user
to collect different types of data that could
be useful in maintenance or in diagnostic
programs. Since the amount of collected
data is very large, the data logger can only
be viewed by means of a PDA or PC. The data
can be up-loaded from EFS2000 to PDA or PC
by the Bluetooth
®
wireless connection. The
local display only allows to view the value of
the configured parameters (see also SET-UP
menu, Maintenance, Set data logger, chap I).
The following data can be viewed on the local
display:
• Logger mode
• Sampling time
• Memory mode
• Date
• Time
Data logger modes:
• OFF: the data logger is not active.
• RECORDER mode: the EFS2000 measures
and memorizes the following 3 data:
• Main voltage supply (V)
• Motor temperature (°C)
• Temperature inside the compartment of
electronics (°C)
• T-RECORDER mode: the ICON2000 measures
and memorizes the following 3 data:
• Torque in OP/CL
• Motor temperature (°C)
• Voltage
In RECORDER and T-RECORDER mode the
‘Sampling time’ fixes the time interval among
two sets of measurements. A maximum of
1024 data points (equivalent to 256 x 4 samples)
can be memorized. The sampling time
can be configured from 1 to 3600 seconds.
START DATE and START TIME fix date and
time to start recording operation. When the
memory is full, the recorder stops recording
or overwrites the previous data according to
the selected MEMORY MODE (‘stop when full’
or ‘continuous’). If ‘continuous’ was selected,
a new set of measured values overwrites the
previous one and the old data is lost. Up to
10.000 cycles of full memory overwriting are
done, then the recorder stops.
In T-RECORDER mode, recording operation
is stopped also in case of an over-torque
alarm, in opening or in closing direction.
This additional feature allows memorizing
the last 256samples and to see the trend
of torque, motor temperature and main
voltage just before the alarm. A new restart
of T-RECORDER clears the data stored in the
memory.
By a PDA or PC the recorded data can be
viewed in a graph where time is on the X-axis
and the measured data on the Y-axis.
The figure below shows a graph with sampling
time 2 seconds in RECORDER mode.
