    Safety Always Read and Observe the Safety Instructions! The device is constructed in accordance with the latest technology and generally accepted safety rules and regulations. Under certain circumstances, however, usage may pose risks to users or cause damage to the device. Commissioning must be carried out by specialist personnel authorized by the operating company.
  • Page 8 Safety Function Check Mode (HOLD Function) After activating configuration, calibration, or service, Stratos Pro enters function check mode (HOLD). The current outputs respond in accordance with the configuration. Operations must not be carried out while Stratos Pro is in function check (HOLD) mode, as the system may behave unexpectedly and put users at risk.
