摘要： A failsafe module comprising an input member (310), an output member (312), and a coupling mechanism for coupling the input member to the output member. The coupling mechanism comprises an intermediate member (316a) movable relative to the output member to energise an energy storage device and a latch mechanism (318, 320) to hold the energy storage device in an energised state. When the latch mechanism is engaged, the input and output members are coupled together and the energy storage device is held in an energised state and isolated from the coupling between the input and output members. When the latch mechanism is released, the energy storage device can release its energy to drive the output member to a predetermined position.

摘要： A motor driven industrial actuator device includes an enclosure (1) in which a motor, a control module (3) and a drive (4) are housed. The drive (4) is coupled between a motor and an external device being actuated. The device also includes an input for receiving an external power supply and a battery pack (6) housed within said enclosure. The battery pack (6) is electrically connected to selectively drive the motor and electrically connectable to the external power supply for charging. The control module (3) is configured to receive data representative of a status of the external power supply, receive data representative of a charge state of said battery pack (6), a status of said battery pack (6), or a charge state and status of said battery pack (6), and cause the battery pack (6) to be charged from the external power supply when an external power supply is determined to be valid and present and the battery pack (6) requires charging. The device also includes at least one temperature sensing device associated with the battery pack (6). The control module (3) is further configured, during charging of the battery pack (6) to: receive from the at least one temperature sensing device, data representative of a measured temperature associated with the battery pack (6); compare the measured temperature with a first predetermined threshold temperature; and if the measured temperature is greater than the first predetermined threshold temperature, cause a charging current delivered from the external power supply to the battery pack (6) to be reduced to prolong the life of the battery pack (6).

摘要： A motor driven actuator device includes an actuator motor; a controller; an input for receiving an external power supply; and a battery pack electrically connected to selectively drive the actuator motor, and electrically connectable to the external power supply for charging. During charging of the battery pack, the controller is configured to compare a measured charge level with a pre-determined charge level required to complete at least two battery shutdown events under battery power alone. During subsequent actuator device operation, the controller is configured to: determine if the external power supply is invalid, instruct a battery shutdown event causing the battery to be discharged, with enough charge in the battery to complete at least one further battery shutdown event; and, subsequently detect when the external power supply becomes valid, and resume actuator device operation under the external power supply, while simultaneously recharging the battery pack to at least the pre-determined charge level.

摘要： A motor driven industrial actuator device includes an enclosure that houses: a motor, a control module, a drive, a battery pack and associated temperature sensor, and an input that receives an external power supply. The control module receives: the status of the external power supply, the charge state of the battery pack, the status of the battery pack, or the charge state and status of the battery pack. The control module causes the battery pack to be charged when an external power supply is present and the battery pack requires charging. During charging of the battery pack, the control module: receives the temperature associated with the battery pack from the temperature sensor; compares the measured temperature with a predetermined threshold temperature; and reduces the current to the battery pack if the measured temperature is greater than the predetermined threshold temperature.
