10.4 MAINTENANCE
10.4.1 Alarm log
The alarm log routine is used to view the list
of the latest 5 alarms and 5 warnings and the
data when they occurred. The “clear alarm log”
routine of the set-up menu should be used to
clear the list.

10.4.2 Torque profile
The torque profile routine gives important
information on the actuator working conditions
in comparison with a previously memorized
reference profile. It can give an indication of a
change in the process conditions.
Details are given of the reference and latest
torqueexpressedin%ofthenominaltorque.
At the end of a full stroke in opening or closing
the ICON 2000 stores the 3 maximum torque
valuesinpositionintervals0%-10%,10%-90%,
90%-100%inopening,andthe3maximum
torquevaluesinpositionintervals100%-90%,
90%-10%,10%-0%inclosing.Timeanddate
of strokes are also saved. The above data are
updated at the end of every full valve stroke and
the previous ones are lost. Function “set torque
reference”, in the SET-UP MENU, Maintenance,
(chapter 7), allows to save the “torque profile”
data in the “torque profile reference” with date
and time. The “torque profile reference” will not
be updated until a new “set torque reference”
command is entered. The user can compare
the last torque profile relevant to the last valve
stroke with the torque profile reference saved
before.
The following definitions will be used:
- B

interval0-10%inopeningor100%-90%in
closing=max.%oftorquetounseatthevalve.
-Peakrunning:maximumtorque%inposition
interval10-90%inopeningor90%-10%in
closing=max.%oftorquewhenthevalve
runs from Breakout to Ending (maximum
mid-travel).
-Ending:maximumtorque%inposition
interval90-100%inopeningor10%-0%in
closing=max.%oftorquetoseatthevalve.
10.4.3 Torque curve
The torque curve routine gives important
information on the actuator working conditions
in comparison with a previously memorized
reference torque curve. It can be used to
perform a detailed analysis of a change in the
process conditions.
During a full valve stroke in opening or closing,
the ICON 2000 measures the torque values
relevanttoevery1%ofpositionvariation.At
the end of the stroke the collected 101 values
(onetorquevalueevery1%ofpositionchange)
are saved in the ICON 2000 memory together
with the time and date of strokes, main voltage,
motor temperature, temperature inside the
electronics compartment and temperature
inside the terminal board compartment. Up to
100 curves in opening and 100 curves in closing
can be saved. When a new curve is available
the oldest one is cancelled and the new one
is memorized. The above data are updated at
the end of every full valve stroke. Data relevant
to a partial stroke are discharged. Function
“set curve reference”, in the SET-UP MENU,
Maintenance, chapter 7, allows to save the full
set of data relevant to 1 off 100 “torque curves”
in the “torque curve reference”. The “torque
curve reference” will not be updated until a new
“set curve reference” command is entered.
The user can compare the last 100 torque
