After power-on LED 1 is blinking for 30 seconds. The device will show the following display.
In case of a high oil mist concentration the LED bar goes up and at 70% opacity compared to the adjusted alarm level the 'Oil-Mist Alarm' LED switches on. At 100% opacity, compared to the alarm level, the 'Oil-Mist Alarm' LED starts blinking. If the opacity later goes down, later the alarm condition will be stored.
The opacity is shown in the right LED bar. If highest LED is switched on the opacity has reached/exceeds the Oil Mist Alarm level.
If a device internal error or a system failure occurs the diagnostics system shows the failure condition by a blinking LED on the LED bar. The error codes are shown in Table 3. A detected oil mist alarm is displayed at this time with the 'Test' LED. In this case the alarm relay or shutdown relay is not switched on.
