Actuator shall conform to ISO 5211 standards for direct mounting onto quarter turn valves. On/Off actuators shall be equipped with internal isolation relays to allow parallel wiring of multiple units. Modulating actuators shall be equipped with a microprocessor-based servo control with on-board diagnostics. Actuator shall be UL, CSA and CE approved. Actuators shall be Bray Series 70 or approved equal. /Asset/Series-70-Actuators.jpg
The advanced circuitry of the BBU continuously monitors battery strength and provides a visual indication (LED) and remote indication (via dry contact). The BBU is housed in sturdy die cast aluminum NEMA 4x (IP 65) enclosure and is factory mounted and factory wired to the Bray Series 70 24 VAC actuator.
Operation
In the normal mode of operation with power supplied to the actuator, the batteries maintain a charge and are in an offline mode. The power applied to the motor is from the power supply, not the batteries.
Upon loss of supply power, after a 10 second startup sequence, the BBU circuitry applies the stored power in the batteries to move the valve or damper to the full open or full closed position designated by the user. The actuator remains in this position until external power is restored to the unit.
For two position (on/off units), and modulating units, the BBU board automatically detects when the actuator has reached the desired position and then disconnects the battery power from the motor. /Asset/BBU-For-Series-70.jpg
The standard AU models are 120V single phase. Three phase units are available as an option. All AU series actuators include two auxiliary switches, torque switches, a position indicator and a heater. Modulating units provide position feedback as standard.
AU series actuators mount directly to Bray butterfly valves and ball valves without the need for adapter bracket. Thermal overload protection is provided by means of PTC thermistors connected directly to the motor windings. /Asset/AU-Series-Actuator.jpg
