Section 9: Set-Up Routines
Close limit by position
• Move the local selector to LOCAL. The local controls can be used.
• Move the valve to closed position (by CLOSE control or by handwheel).
• Move the local selector to OFF.
• Press YES to conrm.
• Press YES to continue with the open limit setting or press NO and again NO to
repeat the close limit setting procedure. Press NO and then YES to exit from the
stroke limits routine.
Close limit by torque
• Move the local selector to LOCAL. The local controls can be used.
• Press the CLOSE control. The actuator moves in closing direction and when the
congured torque value is reached the motor is stopped and the new position
limit is memorized.
• Move the local selector to OFF.
• Press YES to conrm.
• Press YES to continue with the close limit setting or press NO and again NO to
repeat the close limit setting procedure. Press NO and then YES to exit from the
stroke limits routine.
Open limit type
Press YES if the open limit type is correct (torque or position), press NO to change it.
Press YES to conrm.
Open limit by position
• Move the local selector to LOCAL. The local controls become active.
• Move the valve to open position (by OPEN control or by handwheel).
• Move the local selector to OFF.
• Press YES to conrm.
• Press YES to exit, or press NO and then YES to repeat the close limit
setting procedure.
Open limit by torque
• Move the local selector to LOCAL. The local controls become active.
• Press the OPEN control. The actuator moves in opening direction and when the
congured torque value is reached the motor is stopped and the new position
limit is memorized.
• Move the local selector to OFF.
• Press YES to conrm.
• Press YES to exit or press NO and then YES to repeat the close limit
setting procedure.
If parameter “direction to close” is changed, both limits (open and close) must be set.
Before leaving the stroke limits routine, the microprocessor calculates the new value of the
position resolution. If the stroke turns are less than 2.7, the message “error re-try” appears
and the stroke limits procedure must be repeated.
