7 Commissioning notes
All information necessary for commissioning is contained in the following:
· This document ("Technical basics" Z4626en)
· Mounting instructions 4 319 2685 0 (M4626)
· HVAC plant diagram
7.1 General checks
Check to ensure that all permissible values as contained in chapter 8 Technical data
are observed.
· 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 fully closed position.
· Fasten the actuator securely to avoid side load.
· Rotary movement check: Manually change the damper setting by pressing the gear
train disengagement button and turn the adapter (only if no voltage is applied).
· Check to ensure that the cables are connected in accordance with the plant wiring
diagram.
· The operating voltage AC 24 V (SELV/PELV) or AC 230 V must be within the
tolerance values.
7.2 Electrical functional check
Check the actuator operating states as follows (also refer to section 9.3 "Connection
diagrams (three-position control)”.

Check the actuator operating states as follows (see also section 9.4 "Connection
diagrams (modulating)"):
· When applying input signal Y = DC 10 V, the actuator turns (clockwise or counter-
clockwise as per the rotary direction switch setting).
· The direction of rotation set at the rotary direction switch must match the desired
damper movement direction.
· After interrupting the AC 24 V operating voltage, the actuator stops.
· After interrupting positioning signal Y, but while operating voltage is still supplied,
the actuator returns to the zero position.
Factory setting: The potentiometers for setting the offset Uo and span DU are set to the
following values: Uo = 0 V, DU = 10 V.
Specify the values set for Uo and DU in the plant papers.
