Commissioning notes

All information necessary for commissioning is contained in the following:
·
This document ("Technical basics" Z4626en)
·
Mounting instructions 4 319 2685 0 (M4626)
·

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.

Electrical functional check

Check the actuator operating states as follows (also refer to section 9.3 "Connection
diagrams (three-position control)".
Wire connections
AC 24 V AC 230 V
1 – 6 4 – 6
1 – 7 4 – 7
1 – 6 / 1 – 7 open 4 – 6 / 4 – 7 open
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
following values: Uo = 0 V,
Specify the values set for Uo and
