7 Commissioning notes
All information necessary for commissioning is contained in the following:
∂ This document ("Technical basics" Z4613en)
∂ Mounting instructions 4 319 2615 0 (M4613)
∂ 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.
∂ 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°.
∂ 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.
7.2 Electrical functional check
∂ When operating voltage is supplied, the actuator must travel from 0° to 90° (or to end
position for rotary angle limitation).
∂ After interrupting the operating voltage, the actuator must return to the zero position.
Check the actuator operating states as follows (see also section 9.3 "Connection
diagrams (two-pos./three-pos.)").
Wire connections
Direction of rotation
AC 24 V DC 24…48 V
1 – 6 (SN) / 2 – 6 (SP) 2 – 6 (SP) from 0° ⇑ 90°
1 – 7 (SN) / 2 – 7 (SP) 2 – 7 (SP) from 90° ⇑ 0°
1 – 6 / 1 – 7 or
2 – 6 / 2 – 7 open
2 – 6 / 2 – 7 open Actuator stays in
position reached
After interrupting the operating voltage, the actuator must return to the zero
position.
Check the actuator operating states as per the truth table in section 9.3.
