Bluetooth menu
To access the Bluetooth menu :
Select CHANGE in the MENU and OK
Enter the password and OK
Select BLUETOOTH and OK.
The PIN code can be modified. This code will be requested when attempting to connect to the
actuator. On/off allows to activate/desactivate the Bluetooth connection. This option is 'on' by
default and is not memorized in case of actuator reboot.
Note : The infrared communication is desactivated on actuators equipped with a Bluetooth interface
.

18 SETTING AND VIEWING TORQUE VALUES

18.1 CLOSING TYPE

The actuator closes on position in the standard configuration. The option to close on torque is normally
selected in the SET UP menu, although this can also be done via the CHANGE menu:
Select change in the MENU and turn to OK to confirm.
Select torque in the CHANGE menu and turn to OK to confirm.
Select the closing type in the TORQUE menu and turn to OK to confirm.
Select on (torque) and turn to OK to confirm.
The (torque) o/c option is for opening and closing on torque.

18.2 TORQUE SETTING

The actuator is delivered with a torque limiting system
set in accordance with the order. Check the following
points if the torque limiter is activated during operation:
- valve stem is clean and properly lubricated,
- valve stem not seized in the stem nut,
- valve gland not too tight.
If the torque needs to be increased, first obtain the approval of
the valve supplier and then proceed as follows:
Select change in the MENU and turn to OK to confirm.
Select torque in the CHANGE menu and turn to OK to confirm.
Select torque setting in the TORQUE menu and turn to OK to
confirm.
Select the setting you want and turn to OK to confirm.
Use the blue selector to increase or decrease the value.
The minimum setting is 40%. Hold the selector in the up or
down position to scroll through values faster.

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.
18.3 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 the TORQUE menu and 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)
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.
