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.
