Demanding applications (Failsafe Low, no delay, sensitivity adjusted for viscous,
conductive material)
Preparation
• Ensure that L3 (green) is lit.
• Turn the delay potentiometer P1 fully counter-clockwise (to minimum).
• Turn trip point potentiometer P2 fully counter-clockwise (to maximum).
• Set dip switches S1 to S4 to OFF (full potentiometer control).
• Set S5 to OFF (low sensitivity).
Configuration
1. Adjust the material level of the process so that the sensor is immersed: L1 (yellow)
should glow. If L1 does not glow, reset S5 to ON (high sensitivity) The appropriate
position of S5 depends on the dielectric properties of the material).
2. Adjust the material level of the process so that the sensor is uncovered, but retains
as much buildup of material as possible on the sensor.
3. Adjust trip point P2 clockwise until L1 stops glowing. To get the true feel for the
correct position, adjust P2 counter-clockwise then clockwise several times to
ensure that L1 stops glowing. (This adjustment is very sensitive, and we recommend
repeating this exercise to fine tune P2, until a very small adjustment causes L1 to
stop glowing.)
Interface detection (Failsafe Low, no delay, sensitivity adjusted to detect an inter-
face)
Preparation
• Ensure that L3 (green) is lit.
• Turn delay potentiometer P1 fully counter-clockwise (to minimum).
• Turn trip point potentiometer P2 fully counter-clockwise (to maximum).
• Set dip switches S1 to S4 to OFF (full potentiometer control).
• Set S5 to OFF (low sensitivity).
Configuration
1. Immerse the sensor in the material that has the lowest dielectric constant. L1 (yel-
low) should glow. If not, reset S5 to ON (high sensitivity).
2. Adjust P2 clockwise until L1 stops glowing.
3. Immerse the sensor in the material that has the highest dielectric constant. L1
should glow.
Delay alarm output
If you want to slow the Pointek CLS300 response, to compensate for turbulence or false
readings, set a delay interval using potentiometer P1, and set S1 and/or S2 to OFF, to
enable the delay for either alarm activation, alarm de-activation, or both.
If an immediate alarm output is critical, set the appropriate switch to ON, to disable the
delay.
