Page 3: Introduction
INTRODUCTION The Evapco Pulse~Pure Integrated Controller offers conductivity control of evaporative cooling water integrated into Evapco’s patented water treatment system. This addendum should be used in conjunction with Evapco’s standard Pulse~Pure ® Installation, Operation, and Maintenance Manual. The Pulse~Pure Integrated Controller is microprocessor-driven with on/off control outputs. It is supplied with a temperature compensated toroidal conductivity sensor and associated mounting assembly for the sensor. -

The Bleed Set point has been pre-set at the factory to 1000µS/cm. Upon start-up and commissioning of the cooling system the Bleed Set Point must be adjusted to the Evapco recommended set point for the specific project. The Evapco set point recommendation is found on the project’s PPF1.0 report. Contact Evapco Water Systems for a copy of the report if it is not available at the job site. - Page 21 Programming settings for Timer (R6) Relay Select the Main Menu icon from the Home Screen Select Outputs icon Scroll down Outputs menu to Alarm(R6) and select Select the Tool icon.

Page 23: Maintenance
MAINTENANCE The controller itself requires very little maintenance. Wipe with a damp cloth. Do not spray down the controller unless the enclosure door is closed and latched. Sensor Cleaning NOTE: The controller must be recalibrated after cleaning the sensor. Frequency The sensor should be cleaned periodically. -
Page 24: Troubleshooting
Check tee for obstruction. Verify flow. Change location of sensor tee. Pre-bleed set too low Check pre-bleed setting compared to % low. Bleed valve stuck open Repair or replace Bleed valve. (Consult your Evapco Rep). Faulty sensor Replace sensor. Improper wiring of probe Correct wiring. - Page 25 TEMP ERROR This error condition will stop conductivity control. It indicates that the temperature signal from the conductivity sensor is no longer valid. This prevents controlling based upon a false conductivity reading. Possible Cause Corrective Action Improper wiring of sensor to controller. Correct wiring Temperature input is set to the incorrect element Reprogram to RTD 1000 Ohm Element...

Page 26: Procedure For Evaluation Of Conductivity Probe
Procedure for Evaluation of Conductivity Sensor Try cleaning the sensor first (refer to Section 6.1). Check the sensor connections to the terminal strip. Make sure that the correct colors go to the correct terminals the connections are tight and that the connectors are pinching on exposed wire lead, not insulation.
