    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.

    Service In the Service mode you can access the following menus: MONITOR Displaying currently measured values. OUT1 Testing current output 1. OUT2 Testing current output 2. (Only if equipped with 2nd current output.) CODES Assigning and editing passcodes. DEFAULT Resetting the device to factory settings. OPTION Enabling options via TAN.

Select variable in the bottom text line using. The selected parameter is shown in the upper display line. As the device is in HOLD mode, you can perform validations using simulators without influencing the signal outputs.
  • Page 97 Service Menu item Remark Assigning passcodes: In the “SERVICE - CODES“ menu you can assign pass- codes to DIAG, HOLD, CAL, CONF and SERVICE modes (Service preset to 5555). When you have lost the Service passcode, you have to request an “Ambulance TAN“ from the manufac- turer specifying the serial number of your device.
