Introduction to the Pointek CLS 100
Note: Pointek CLS 100 is to be used only in the manner outlined in this instruction manual.
The Pointek CLS 100 capacitance level switch provides 4 or 20 mA output and solid state
switch contact for detection of high and low process material levels. When the measured
material approaches or contacts the switch's probe, an increase in capacitance is sensed
and a high level alarm can be triggered. If a low level alarm is required then the lack of
material contact is sensed and this condition triggers the low level alarm.
Pointek CLS 100 Features
•NPT, BSPT process connections
•Corrosion resistant construction, Kynar®and 316 stainless steel wetted parts
•Non-polarized, solid-state switch
•4 or 20, and 20 or 4 mA loop alarm output
Pointek CLS 100 Applications
•Liquids, slurries, powders, granules, and solids
•Foods and pharmaceuticals
•Chemical and petrochemical
•Relatively high pressure and temperature
•Hazardous areas

Definitions
Alarm Conditions as defined below can be detected in a fail-safe or non fail-safe mode.
Fail Safe
•The sensor connection arrangement of the CLS 100 is fail-safe if the output status is in
alarm status when power fails, which is an open contact state.
•The sensor connection arrangement of the CLS 100 switches to the alarm status when
power fails, which is an open contact state.
High Alarm
•Condition in which the material has reached a maximum level for the process (probe
covered).
Low Alarm
•Condition in which the material has reached a minimum level for the process (probe
uncovered).

Protection Diodes
Always use a protection diode when driving an external relay with the solid state switch. This
prevents possible switch damage due to inductive spikes generated by the relay coil.
Orient the diode based on the current flow.

Operation
Unscrew the clip to access the terminals.
Setup
Note: Setup can be done in the field with the Pointek CLS mounted into process, or in the
shop prior to mounting.
Start Up
After the CLS is properly mounted and wired, apply power to the unit. The green LED lights to
indicate the unit is powered and operational.
Indicators
Three LEDs indicate the following:
Yellow =sensor status: When the trim pot is properly set, this LED
indicates when the sensor is in contact with the
process material (material capacitance is greater
than the setpoint).
This LED is off when the sensor is out of contact
with the process material (material capacitance is
less than the setpoint).
Red = output status: This LED indicaties the mA loop alarm and solid
state switch contact status. Refer to
Alarm Output Status on page 12.
Green = power: This LED is on when the Pointek CLS is properly
powered.

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.
1. With sensor uncovered and a minimum 100 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
.
