7-4 EB 3018 ENOperation4. Based on a closed restriction, turn the setpoint adjuster counterclockwise () toadjust the flow rate set point.5. Check the flow rate at the heat meter andcorrect it, if necessary.6. Once the flow rate is set as required,lock the setting with the locking screw(2.6).7. Close a possibly open bypass valveagain.8. Lead-seal the setting, if necessary.Once the magnet has been released, thespring mechanism pushes the actuator stemback to the fail-safe position.7.2.2 DN 65 to 100Type 5824-30 or Type 3374 Electric Actua-torÎ Adjustment without actuator · SeeFig. 7-11. Thread the lock nut (2.2) upwards on therod (2.1).2. Loosen the locking screw (2.6) and turnthe set point adjuster (2.3) clockwise ()as far as it will go to close the restriction(2.7). Close the restriction (2.7).3. Determine the turns required to achievethe desired flow rate from the adjustmentdiagrams (see Table 7-2).Note4. Turn the set point adjuster (2.3) counter-clockwise () by the corresponding num-ber of turns.5. Thread the lock nut (2.2) clockwise ()as far as it will go onto the rod (2.1). Therestriction opens until the adjusted setpoint is reached.6. Check the flow rate and correct it, if nec-essary. Secure this setting with the lock-ing screw (2.6).7. Retract the actuator stem (1.1) using themanual override. Place the actuator onthe restriction connection. Secure it bytightening the hex nut (1.3, see 'Tighten-ing torques' in Annex).8. Extend the actuator stem all the way tothe rod (2.1) using the manual override.9. Position the stem connector clamps (1.2)and screw them tight.10. Thread the lock nut (2.2) all the way tothe top toward the stem connectorclamps (1.2) and lock in place (see'Tightening torques' in Annex).Î Adjustment with actuator · See Fig. 7-1More details on the Type 5824-30 ElectricActuator in u EB 5824-1 and u EB 5824-2;more details on the Type 3374 ElectricActuator in u EB 8331-3 and u EB 8331-4.
