Torque Limits
Torque limits are used as a reference for torque alarm and end of travel. With the 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 the same particular application, it is useful to configure
3 different torque thresholds for each travelling direction, to limit separately the unseating,
running and ending torque. To select this option pick “3-point limits” and then follow the
torque set-up and stroke limits routines (see Figure 50).
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 and then NO to select “torque mode”. Press YES if setting is correct,
press NO to change. Press YES when the value is correct.
•
Repeat stroke limits setting routine.
