Electrical parallel connection of actuators Same device types with index A can be electrical parallel wired. Same device types with index B (or higher) can also be electrical parallel wired. Mix of electrical parallel wiring of device types with index A and B (or higher) is not possible. Up to 10 actuators of the same device type can be electrical parallel wired. Cable length and cable cross section have to be respected. See chapter 6 “Wiring notes” for more information.

The shaft adapter as well as all other individual parts are not premounted, as the actuator components are put together differently depending on damper shaft length. Refer to section 2.5 “Mechanical design".
6 Introduction Wiring notes Prior to wiring, study all information in the following sections: · "Safety notes" in section 4.1 · "Device-specific regulations" in section 4.2 · "Notes on EMC optimization" in section 4.3 · "Connection Diagrams" in chapter 9, and the · HVAC plant diagram. 6.1 Permissible line lengths and cross sectional area The permissible line lengths and cross-sectional areas depend on the actuators’ power consumption and the voltage drop of the connection lines to the controller.
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 cross-sectional area. 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 24 The values in [VA, W] on the P-axis are allocated to the permissible voltage drops (DU/2U = 4 %) on line L as per the above table and to the P&I diagram.
The following sections show how to determine the permissible line length and crosssectional areas for the various actuators based on examples. The examples for actuators connected in parallel apply to the following arrangement: G0 G L2 A1 L2 A2 L2 A3 L2 A4 G0 G L1 G0 G Controller G0 L1 G G0 G G0 G Assumption 4614S01en Line length for actuators connected in parallel The line resistances of L2 are equal and can be ignored for L1.
Note: 2-position control It is recommended to switch off the power during two-position control when the actuator has reached the open or close position, in order to enhance life span and reduce power consumption. 6.3 Modulating actuators GBB/GIB16..1 Power consumption and perm. voltage drop with one actuator P&I diagram: Currents Actuator wiring (modulating) With AC supply, the G0 line has a AC 0.33 A supply current and a DC 0.1 mA positioning signal current (from Y = DC 0...10 V).
6.4 Actuator wiring (Modbus RTU) The damper actuators are supplied with a prewired connecting and communication cable. All interconnected devices must be connected to the same G0.

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 29.
