The is connected with the valve stem by a button keyed retainer connection. An integrated spring package limits the stem force to a factory-adjusted value in either direction. Installed microswitches switch off the actuator precisely when the specified stem force is reached. anual Operation Actuators without spring return are equipped with a manual operator used in case of power failure. anual operation is possible only after the power supply has been switched off or disconnected. To operate, push the manual operator knob down and turn clockwise to move the stem downward and counterclockwise to move the stem upward. If the actuator returns to automatic control, the manual operator knob unlocks automatically. In the case of actuators with spring return, the manual operator is located under the cover. Spring Return The A,B spring return actuators provide a defined safety position of the valve in case of power failure. The spring return actuators are shipped from the factory with a shipment stop (to lock the knob) in order to allow connection of the stem button retainer to the valve stem without power supply. Electrical Installation The actuators are delivered with a pre-installed cable gland x. and two additional knock-outs for 6x. and x.. EB-3GE R
