1.13.3 TORQUE LIMITS
Torque limits are used as a reference for torque alarm and end of travel. With option
"standard", the torque limits are constant along the full stroke. The limits can be configured
in the "stroke limits" or "torque set-up" routines and determine the torque alarm or end of
travel situations. In some special applications it is useful to configure 3 different torque
thresholds for each travelling direction, so as to separately limit the unseating, running and
ending torque values. To select this option pick “3-point limits” and then follow the torque
set-up and stroke limits routine (see figure).
Configuration procedure:
• Move the local selector to OFF and then simultaneously press OPEN and STOP. Select
the language and then enter the password according to the instructions (see “Entering the
set-up mode”). When the message of the display is “SET-UP MODE OK?” press YES.
Press YES to select the actuator set-up menu, press NO to scroll the list of available
routines and then press YES to select Miscellaneous.
• Press NO, and then NO to select “torque mode”. Press YES if the setting is correct, press
NO to change it. Press YES when the value is correct.
• Repeat the “stroke limits set-up” routine.
1.13.4 LITHIUM BATTERY
On request, the actuator can be provided with a lithium battery to update the remote outputs
(output relays status and bus messages) in case of electrical power failure and manual
override operations. The program runs the functions relevant to the battery only if the
appropriate flag “lithium battery” is configured with “present”. If the battery is absent or if no
updating of remote outputs is requested, the above flag should be configured with “absent".
Configuration procedure:
• Move the local selector to OFF and then simultaneously press OPEN and STOP. Select
the language and enter the password according to the instructions (see “Entering the set-
up mode”). When the message displayed is “SET-UP MODE OK?” press YES. Press YES
to select actuator set-up menu, press NO to scroll the list of available routines and then
press YES to select Miscellaneous.
• Press No to scroll the list of routines and press YES to select lithium battery. Press YES if
the setting is correct, press NO to change. Press YES when the value is correct.
