Calibrating Calculated Ppm; Manual Relay Control - Pentair AK110 Installation And User Manual

Table of Contents

EXAMPLE 1: The default set point is 700, the PPM hand measurement is 1 .0 (2 .0 PPM desired), and the current

display shows a measurement of 690 mV . From the above table the hand PPM is low and the ORP is below the set

point . The chemical feed times are not high enough for the ORP to reach the set point and should be increased .

EXAMPLE 2: From example 1 change the hand measurement to 4.0 PPM with ORP reading 700mV. From the above

table the hand PPM is high and the ORP is below the set point. The ORP should be calibrated to 700 + (4.0 – 2.0) * 10 =

720 .To compare ORP measurements to PPM measurements per actual pH readings refer to the calculated PPM chart on

page 131 .

If you have an ORP sensor module and Calculated PPM mode selected . You can calibrate the Calculated PPM in the

following manner . Measure the PPM using a standard test kit . To calibrate the PPM, move the cursor to PPM and press

ENTER . Enter the value obtained from the test kit in the value entry screen . Press ENTER again to save your changes .

You can enter the password 9003 to see the ORP and adjusted ORP being

used for calculated PPM. These ORP values will only be displayed for four

Always make sure the pH is at the pH setpoint and PPM is greater than

Always control at PPM levels greater than 1.0 PPM when using

Display Screens

Position the cursor to the left of the status word and press

ENTER to toggle the relay on and off . The length of time the

relay stays on is adjustable in the programming. When the

relay is toggled to OFF the relay immediately goes back to

automatic control and in some cases may immediately turn

back ON .
