This application guide is an addition to the operating instructions. Please review CLS200
(Standard Version) operating instructions to ensure that the device is properly mounted.
This application guide provides a basic procedure for setting the switch point for correct
operation of the CLS200 (Standard Version) in either covered or uncovered states. Please
note that the guide applies only to hardware manufactured after August 2010 as indicated by
a serial number of PBD/A8xxxxxx or higher. (For example, PBD/A9xxxxxx or PBD/B2xxxxxx.)
Included in the guide are the appropriate start up procedures to quickly and effectively set up
the Pointek CLS200 (Standard Version) capacitance switch for general applications,
demanding applications and interface detection. It also contains instructions for adjusting the
setpoint and alarm delay.
For more detailed information, please consult the operating manual (A5E47827796).

3.1 Adjusting the Setpoint
Before adjusting the setpoint or alarm delay the cover must be removed.
Prior to removing the cover, please ensure that power is removed, and that the application
and installation allow for removal of the cover. (This may not be permitted in some
Hazardous Areas.)
Once the cover has been removed, apply power to the unit. The green power LED (L3) will
glow indicating that the unit is powered and operational. If L3 is not on, please consult the
Specifications and Troubleshooting sections of the operating instructions.
3.2 Pointek CLS200 Applications
Pointek CLS200 can be set up for three different applications which are described in the table
below. Use the calibration procedure for the application that most closely describes your
operation.
Application

3.3 Calibration for general applications (Failsafe low, no delay)
Pointek CLS200 Capacitance Switch (Standard Version)
Application examples, 09/2020, AG080910 7
3.3 Calibration for general applications (Failsafe low, no delay)
1. Ensure that the green power LED (L3) is on.
2. Set DIP switches S1 to S4 to OFF (rocker down as shown in the diagram above).
3. Enable SETUP mode by setting DIP switch S5 to ON (rocker up, opposite to diagram above).
4. Turn the delay potentiometer (P1) fully counter-clockwise.
5. Adjust the material level of the process so that the probe is uncovered.
6. If the yellow sensor status LED (L1) is on, proceed to step 7. If L1 is off, turn the trip point
potentiometer (P2) counter-clockwise until it just turns on.
7. Slowly turn the trip point potentiometer (P2) clockwise until the yellow sensor status LED
(L1) just turns off.
8. Enable RUN mode by setting DIP switch S5 to OFF (rocker down).
3.4 Calibration for demanding applications (Failsafe low, no delay)
1. Ensure that the green power LED (L3) is on.
2. Set DIP switches S1 to S4 to OFF (rocker down as shown in the diagram above).
3. Enable SETUP mode by setting DIP switch S5 to ON (rocker up, opposite to diagram above).
4. Turn the delay potentiometer (P1) fully counter-clockwise.
5. Adjust the material level of the process so that the sensor is immersed.
6. Adjust the material level of the process so that the sensor is uncovered, but retains as much
buildup of material as possible.
7. If the yellow sensor status LED (L1) is on, proceed to step 8. If L1 is off, turn the trip point
potentiometer (P2) counter-clockwise until it just turns on.
8. Slowly turn the trip point potentiometer (P2) clockwise until the yellow sensor status LED
(L1) just turns off.
9. Enable RUN mode by setting DIP switch S5 to OFF (rocker down).
3.5 Calibration for interface detection (Failsafe low, no delay)
1. Ensure that the green power LED (L3) is on.
2. Set DIP switches S1 to S4 to OFF (rocker down as shown in the diagram above).
3. Enable SETUP mode by setting DIP switch S5 to ON (rocker up, opposite to diagram above).
4. Turn the delay potentiometer (P1) fully counter-clockwise.
5. Adjust the material level of the process so that the sensor is covered by the material with the
lowest relative dielectric constant.
6. If the yellow sensor status LED (L1) is on, proceed to step 7. If L1 is off, turn the trip point
potentiometer (P2) counter-clockwise until it just turns on.

3.6 Alarm Delay Function

7. Slowly turn the trip point potentiometer (P2) clockwise until the yellow sensor status LED
(L1) just turns off.
8. Enable RUN mode by setting DIP switch S5 to OFF (rocker down).
3.6 Alarm Delay Function
If you want to slow the Pointek CLS200 response, to compensate for turbulence or false
readings, set a delay interval using the delay potentiometer (P1) and set DIP switches S1
and/or S2 to the OFF position to enable the delay for either alarm activation (S1 OFF), alarm
de-activation (S2 OFF), or both (S1 and S2 OFF).
Note: This information can usually be found inside the device cover.
If an immediate alarm output is critical, disable the delay by setting the appropriate switch
(either S1 or S2) to ON. The functioning of switches S1 and S2 depends on the alarm setting:
High alarm/ overfill protection
S1 - ON
disables delay of alarm de-activation
(alarm OFF)
S2 - ON
disables delay of alarm activation
(alarm ON)
Low alarm/ dry run protection
S1 - ON
disables delay of alarm activation
(alarm ON)
S2 - ON
disables delay of alarm de-activation
(alarm OFF)
3.7 Testing the Alarm Delay
This test procedure assumes that you have completed one of the calibration processes
described previously.
1. Grasp the probe with your hand. The yellow sensor status LED (L1) should turn on
immediately. The red output status LED (L2) should turn on after a delay.
2. Turn the delay potentiometer (P1) clockwise about 1/8 of a turn.
3. Turn DIP switch S4 to the ON position; this will simulate a change in state of the probe
(covered/uncovered).
4. L1 (the yellow LED) should turn on immediately, and L2 (the red LED) should turn on after a
longer delay than in Step 1.
5. Turn DIP switch S4 to the OFF position.
6. Continue to adjust the delay potentiometer (P1) until you have the desired delay.
3.8 Operation
After completing the setup, replace the lid and secure the lid clip. Pointek CLS200 Standard
model is now ready to operate.
