 Mainalarm Relay | The Relay 1 (usually used as Main Alarm relay) can be switched on and off manually for testing purposes. | ||
 Alarm2/Pre Relay | The Relay 2 (often used as pre-alarm relay) can be switched on and off manually for testing purposes. | ||
 Sensor cleaning | OFF – default. System works in accordance with specification. ON – as soon as ON is selected, the system enters a special maintenance mode where alarms will not be triggered until the system restarts. This is used when sensors need to be pulled out of the engine and cleaned. After cleaning press [Esc] button; sensors will be calibrated automatically and then the system restarts.! Attention By pressing [Esc] button the Evaluator will recalibrate the whole sensor chain. This requires that all sensors of the chain are cleaned (not only several sensors)! | ||
 Temp. calibration | OFF – default. System works in accordance with specification. ON – as soon as ON is selected, the screen awaits user input of calibration temperature. Press [▲] or [▼] buttons to set the correct temperature of the sensor environment. Initial value is 60°C. Possible range: 20°C – 90°C. Pressing [Esc] leaves the current sensor temperature unchanged. On pressing [Enter] the system calibrates sensor temperatures, the message “Calibrating temperature busy!“ appears. After successful calibration the system restarts automatically. | ||
