- Page 1 Pointek CLS 200 Capacitance Liquids/Solids Instruction Manual Instruction Manual PL-540 February 1998 33455400 Technology based. Customer driven.
- Page 3 Pointek CLS 200 is to be used only in the manner outlined in this instruction manual. The Pointek CLS 200 capacitance level switch provides output on high or 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.

Page 18: Setpoint Adjustment
ALARM OUTPUT ALARM OUTPUT STATUS high alarm alarm SETPOINT ADJUSTMENT In order to assist you in properly adjusting the alarm setpoint for reliable and accurate detection of the process material, we have categorized the materials and applications into three cases. Follow the setup procedure associated to the case which covers your application. Case 1: this is the general case encountered in most applications, characterized by the following:... - Page 19 trip point switches delay sensor power status (green) output (yellow) status (red) Case 1 - insure that L3 (green) is ‘ on ’ Preamble: - turn both potentiometers, P1 and P2, fully ccw (counterclockwise) - set S1 switches 1 to 4 ‘ off ’ and S1 switch 5 to ‘ on ’ (normal sensitivity) 1.
- Page 20 DELAY The alarm actuation can be delayed for either or both ‘on alarm’ and ‘off alarm’ conditions. The selection is made by setting S1-1 and S1-2, refer to Set Up \ Switch Bank. The amount of delay is adjustable from 1 to 60 seconds by setting potentiometer, P1. After completing the set up, replace the Pointek CLS lid and lid clip.

Remove the insulation covering the solder connections. 4. Unsolder the connections. Do not cut the connection to the probe leads, as this can render them too short to work with later. 5. Remove the sheathing around the tension block. Remove the block for reuse in step 7, and cut off the excess length of cable.
