Operation
4.2 Alarm output
Preparation
• Ensure that the green LED is ON.
• If yellow LED is ON, turn the trimpot CCW (counter clockwise) until the yellow LED goes
OFF, otherwise go to step 1 below.
Configuration
1. With sensor uncovered and a minimum 50 mm free space all around, turn the trimpot CW
(clockwise) until the yellow LED just goes ON.
2. Turn the trimpot CCW until the yellow LED just goes OFF.
Case 2: Demanding applications
Characteristics
• hygroscopic / wet solids
• high viscosity and high conductivity liquids
Preparation
• Ensure that the green LED is ON.
• Turn the trimpot CCW (counter clockwise), until the yellow LED goes OFF.
Configuration
1. Adjust the material level of the process so that the sensor is immersed. The yellow LED
should be ON.
2. Adjust the material level of the process so that the sensor is uncovered, but retains
significant (as much as possible) material buildup on sensor.
3. Adjust the trimpot CCW until yellow LED goes OFF. To get the true feel for the correct
position, please adjust the trimpot CW then CCW several times to ensure that the yellow LED
is OFF. (This adjustment is sensitive, and we recommend this practice exercise so you can
fine tune the trimpot movement until the yellow LED L1 turns OFF with minimal
adjustment.)
Case 3: Interface detection
Characteristics
• liquid A / liquid B, foam / liquid
Preparation
• Ensure that the green LED is ON.
• Turn the trimpot CCW (counter clockwise), until the yellow LED goes OFF.
