Description of torque limit system:
All torque values are expressed as percentages. 100% corresponds to the maximum setting for the
actuator. This value is shown in Nm on the actuator nameplate.
- closing % : limits torque during closing
- close tight %: this option is only displayed if closing
is on torque limit. In this case, the torque applied on
the valve seat may be not be the same as the torque
limit during the closing movement.
- open breakout %: this option is only displayed
if closing is on torque. In this case, the torque limit
to unseat the valve may be different from - generally higher
than - the torque limit during the opening movement.
If the setting is above 100% the display shows no
limitation (equivalent to override on the torque limiter at the start of the opening movement).
- opening %: limits torque during opening movement.
20.3 TORQUE READINGS AND COMPARISON WITh ORIGINAL
TORQUE VALUES
Maximum resistive torque values are measured for all
motorised movements and can be viewed later.
Operating torque values for a movement can be stored
in memory to allow comparison against torque values
for the most recent motorised movement.
Select change in the MENU and turn to OK to confirm.
Select torque in the CHANGE menu and turn to OK to confirm.
Select measured torque in TORQUE menu, turn to OK to confirm.
Select the torque value required and turn to OK to confirm.
The display shows the maximum torque value measured during
the most recent motorised movement. (note: movements are not
measured when settings are being made)
If the torque values for a previous motorised movement have
been stored in memory, these values can be viewed in the next
line for reference.
Example: in this example, the torque reading on the initial movement
was 12% and the torque on the most recent movement is 18%.
The two values can be compared to determine whether any
preventive maintenance is required.
Storing motorised movement torque values
To save torque values for a motorised movement, select SAVE in the menu and then select:
torque => ref (yes).
Reference torque readings take the torque values for the most
recent motorised movement. If an error occurs, select: torque =>
ref (no) to restore the existing reference torque values.
Values are only stored in memory when the user exits
the CHANGE menu confirms (change ok?)
Displaying the position / torque curve for the most recent motorised movement
Select torque curve in the torque menu and turn to OK to confirm.
Select open or close movement and then turn to OK
to confirm.
The curve is shown on the display screen
with position from 0 to 100% and torque from
0 to 100% (100% is the maximum torque value on the
actuator nameplate)

Note: Actuator settings must be made
again after making changes to the tight
torque setting (valves closing on torque)
Reminder: to save changes, exit
menus by selecting return until the
(change ok?) message is displayed
To view settings without making
changes, select check instead
of change in the menu.

21 CUSTOMIZING STATUS AND CONTROL INDICATIONS
18.1 LOCAL INDICATION
The local display can be configured as follows:
Invert display: the display can be inverted (rotated 180
degrees). Select Change in the menu, then signaling, then local
then invert display (yes).
Display torque: select this option to have the real-time torque
value displayed on the actuator display at the same time as the
position.
Select Change in the menu, then signaling, then local then
display torque (yes).
Red & Green LEDs: in the standard configuration, the red light indicates that the valve is closed and
the green light means it is open. The assigned colours can be changes so that the red light indicates
that the valve is open and the green one means it is closed.
Select change in the menu, then signaling, then local then lights: Red=(open)
To keep the valve open and valve closed labels in the correct position on the
indicator, you must also open the cover with the window and turn round the display indicator plate.
21.2 REMOTE INDICATIONS
Signals giving actuator status data are transmitted via bistable relays. Each relay can be configured
applying a list of available options.
INTELLI+ has four bistable relays in the standard configuration. A further three bistable relays can
be added as an option (the contact is open when there is no power).
The equipment is configured at the factory in accordance with the order.
Changes can be made as follows:
Select change in the MENU and turn to OK to confirm.
Select signaling in the CHANGE menu and turn to OK to confirm.
Select remote in the SIGNALING menu and turn to OK to confirm.
Select the relay in the SIGNALING menu and turn to OK to
confirm.
Choose contact type (i.e. activated contact status) and turn to
OK to confirm.
Choose function or functions required:
Several options can be selected for a single relay.
When an option is selected, the brackets are removed and an
asterisk * is displayed in front of the selected item. Turn to OK
again to cancel selection.
