Commissioning Workflow 1 The devices are especially designed for using the Climatix push-button configuration as de1) scribed in document A3975 . The bus configuration can alternatively be parameterized by the local HMI, cf. page 5. During commissioning check/set the following: ∂ Bus configuration (address, baudrate, transmission mode, and optionally termination). The default address 255 allows to mount and power multiple actuators at the same time without interfering with each other.
HMI (Human-Machine Interface) Push-button operation 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. press 1x shortly LED flashes 1x blue 3.
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. Push-button addressing Display current address (starting with lowest address digit) The Modbus address can be set without a separate tool by using the push-button and LED.
