3.5.1 Stored-energy motorized operating mechanism
Motorized operating mechanism for VL160X-VL800
● The stored-energy motorized operating mechanism is suitable for synchronization tasks.
● The motor charges a stored-energy spring mechanism and moves the SENTRON VL
toggle handle to the "OFF/RESET" position.
● The stored-energy spring mechanism discharges when actuated, quickly switching the
SENTRON VL toggle handle to the "ON" position.
● A changeover switch allows local (Manual) or remote (Auto) operation to be selected.
● The manual actuator handle is located on the front of the operating mechanism cover.
