Cable types ∂ Cables emitting interference: ∂ Cables susceptible to interference: ∂ You can run both cable types in the same cable ducting, but in different compartments. If ducting with three closed sides and a partition is not available, separate the interference-emitting cables from other cables by a minimum of 150 mm or route in separate ducting.

The shaft adapter as well as all other individual parts are not pre-mounted, as the actuator components are put together differently depending on damper shaft length. Refer to "2.5 "Structure and design" in this chapter.

Line length/consumption AC 24 V The diagram applies to AC 24 V and shows the permissible line length L as a function of consumption P and as a parameter of the line cross sections. 4626D02en L [m] 300 200 2.5 mm² 0.75 mm² 100 1 mm² 1.5 mm² 0.5 mm² 0 8 0 Notes on diagram ∂ ∂ P&I diagram: Voltage drop on the supply lines 16 The values in [VA, W] on the P-axis are allocated to the permissible voltage drops (ΧU/2U = 4 %) on line L as per the above table and to the P&I diagram.

Push button operation 7.3 Modbus 7.3.1 HMI – Human-machine interface Activity Push-button operation Confirmation Display current address Press button < 1s 1-digits: red (starting with lowest address digit) 10-digits: green 100-digits: orange If termination is switched on, LED flashes 1x blue after address display Example: 124 = 4x red, 2x green, 1x orange Turn bus termination on / off turn on 1.press 3x LED flashing and flickering stops (termination mode) 2.
Resetting the device by push button 1. 2. 3. 4. Press button for >10s → LED starts flashing orange. Release button while LED still flashes → LED keeps flashing for 3s. If the button is pressed within these 3s, the reset is cancelled. After those 3s → LED shines red (reset), then the device restarts. 7.3.2 Push button addressing The Modbus address can be set without a separate tool by using push-button and LED. To display the current address, press button <1s.
Set address “5”: 1. Enter addressing mode 2. Set 1- digit: Press button 5-times → LED flashes green per button press Store address: press button until LED shines red → address is stored and displayed 1x for confirmation 7.3.3 Commissioning Workflow 1 The devices are especially designed for using the Climatix push-button configuration as described in document A3975 1). The bus configuration can alternatively be parameterized by the local HMI, cf. page 28.
