Environmental conditions
Check to ensure that all permissible values as contained in chapter 8 "Technical data" are observed.
Mechanical check
Check for proper mounting and to ensure that all mechanical settings correspond to the plant-specific requirements. Additionally, ensure that the dampers are shut tight when in the closed position.
Fasten the actuator securely to avoid side load.
Check the rotary movement: Manually set the damper by turning the adapter using a hex wrench, and lock the gear train as per the mounting instructions (only if no voltage is applied).
Check the unlocking mechanism of the gear train by turning the hex wrench in the direction of 90°.
Electrical check
Check to ensure that the cables are connected in accordance with the plant wiring diagram.
The operating voltage AC 24 V/DC 24…48 V (SELV/PELV) or AC 230 V must be within the tolerance values.
