50-608 Kotron Model 811 RF Point Level Sensor
1.8.3 Low Level Alarm
Fail-safe Low – with media on the probe:
1. Set DIP switch positions 1 OFF, 2 OFF, 3 ON and
position 4 OFF. LED will be ON.
2. Turn the COARSE control clockwise until the LED
turns OFF.
3. Slowly turn the COARSE control counterclockwise until
the LED is ON.
4. Turn the FINE control clockwise until the LED goes OFF,
then counterclockwise until the LED stays ON.
1.8.4 High Level Alarm
Fail-safe High – with no media on the probe:
1. Set DIP switch positions 1 ON, 2 ON, 3 ON and
position 4 OFF. LED will be OFF.
2. Turn the COARSE control clockwise until the LED
turns ON.
3. Slowly turn the COARSE control counterclockwise until
the LED is OFF.
4. Turn the FINE control clockwise until the LED stays ON.
1.8.5 High Level Alarm
Fail-safe High – with media on the probe:
1. Set DIP switch positions 1 ON, 2 ON, 3 ON and
position 4 OFF. LED will be OFF.
2. Turn the COARSE control clockwise until the LED
turns ON.
3. Slowly turn the COARSE control counterclockwise until
the LED is OFF.
4. Turn the FINE control clockwise until the LED turns
ON, then counterclockwise until the LED stays OFF.
1.8.6 Time Delay
If Time Delay is needed for any reason (e.g., surface waves
causing relay chatter), the following two choices must
be made:
Delay Function
• Delay on FILL (rising level) is DIP switch 2 ON.
• Delay on EMPTY (falling level) is DIP switch 2
OFF.
Delay Duration
• 0.5 to 7 second delay – DIP switch 3 ON, 4 OFF.
• 2 to 120 second delay – DIP switch 3 OFF, 4 ON.
• Clockwise rotation increases duration.
