PF = Power Fail Product Features Pre‐charge time (start‐up) When the failsafe actuator is new from Belimo, or the application has experienced a long duration power loss, the failsafe actuators require a pre‐charging time. This time is used for charging the capacitors to a minimum voltage level. This ensures that, in the event of an electricity interruption, the actuator can move from its current position into the preset emergency Power Off Position (POP). The duration of the pre‐charging time depends mainly on following factors: – Duration of the electricity interruption – PF delay time (bridging time) Typical pre‐charging time: [d] = Power interruption in days [s] = Pre‐charging time in seconds PF[s] = Bridging time Calculation example: Given an electricity interruption of 3 days and a bridging time (PF) set at 5 s, the actuator requires a pre‐ charging time of 14 s after the electricity has been reconnected (see graphic).

Product Features Application For proportional modulation of dampers in HVAC systems. Actuator sizing should be in accordance with the damper manufactures specifications. The actuator is controlled via the Belimo Cloud, BACnet/IP or Modbus TCP and drives to the position defined by the control variable. Multiple data points can be written and read via the control interface. Local control mode: The actuator receives an analog control signal from a conventional controller and drives to the control position. In addition, using the Belimo Cloud, BACnet/IP or Modbus TCP, various data points can be read and with the exception of the control signal written to the actuator. This Belimo Cloud connected damper actuator has two universal sensor inputs ready for your innovative HVAC applications. The two universal sensor inputs (passive, active, or contact) serve as an analog/digital converter for the digital transmission of the sensor value to a higher level system. Selecting the sensor type is accomplished via connection to the integrated web server (RJ45 connection to the web browser) or directly via the Belimo Cloud. The actuators performance and sensor data is recorded locally with 13 months of storage. This data can be used for analytical purposes, downloaded via csv files, or used in your HVAC application. Operation The AKB actuators use a brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode. The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The AKB series provides 95° of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover. The anti‐rotation strap supplied with the actuator will prevent lateral movement. Add‐on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions. Converter for sensors Connection option for two sensors (passive, active, or contact). The actuator serves as an analogue/digital converter for the transmission of the sensor signal to the higher level system. Communication The parameterization can be carried out through the integrated web server (RJ45 connection to the web browser), by communicative means or via the Cloud. Additional information regarding the integrated web server can be found in the separate documentation. Position signal inversion Signal inversion in cases of control with an analogue positioning signal. The inversion causes the reversal of the standard behavior, i.e. for control signal 0%, the actuator is opened to Max and for control signal 100%, the actuator would close. Data recording The recorded data (integrated data recording for 13 months) can be used for analytical purposes. Download the csv files via the built‐in web browser. Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops. Delivery state (capacitors) The actuator is completely discharged after delivery from the factory, which is why the actuator requires approximately 20 s pre‐charging time before initial commissioning in order to bring the capacitors up to the required voltage level. Actuator parameters The factory settings cover the most common applications. Individual parameters can be modified with the Belimo Service Tool, ZTH. In addition the ZTH is used as a gateway to a PC for the PC‐Tool. Direct mounting Simple direct mounting on the damper spindle with an universal spindle clamp, supplied with an anti‐ rotation device to prevent the actuator from rotating. Manual override Manual override by push‐button keeps the gear is disengaged for as long as the button is pressed.

High functional reliability The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached. Home position The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating range and position feedback adjust themselves to the mechanical setting range. The actuator then moves into the position defined by the direction of rotation switch and desired positioning signal. Adaption and synchronization An adaption can be triggered manually by pressing the “Adaption” button or with the PC‐Tool. Both mechanical end stops are detected during the adaption (entire setting range). A range of settings can be adapted using the PC‐Tool (see MFT‐P documentation). Power Off Position (PoP) dial setting The «power fail setting position» rotary knob can be used to adjust the desired emergency setting position (POP) between 0 and 100% in 10% increments. The rotary knob refers only to the adapted angle of rotation range between 30 and 95°. No set Min or Max values are observed. In the event of a power interruption, the actuator will move into the selected emergency setting position (POP), taking into account the bridging time that has been set. Settings: The rotary knob must be set to the «Tool» position for retroactive settings of the emergency setting position (POP) with the Belimo service tool MFT‐P. Once the rotary knob is set back to the range 0…100%, the manually set value will have positioning authority. Bridging time Electricity interruptions can be bridged up to a maximum of 10 s. In the event of an electricity interruption, the actuator will remain stationary in accordance with the set bridging time. If the electricity interruption is greater than the set bridging time, then the actuator will move into the selected emergency setting position (POP). The factory bridging time set is 2 s. This can be modified on site in operation with the use of the Belimo service tool MFT‐P (PC‐Tool). Settings: The rotary knob must not be set to the “Tool” position! For retroactive adjustments of the bridging time with the Belimo service tool MFT‐P or with the ZTH EU adjustment and diagnostic device only the values need to be entered.
