Calculated Ppm; Akcolor Ppm; Temperature Sensor; Flow Sensors - Pentair AK110 Installation And User Manual

If you have an ORP sensor module you can choose to operate the AK110 in Calculated PPM (Parts Per Million) mode .
When in Calculated PPM mode, the Controller uses a special formula to convert the ORP reading from the sensor in to
PPM units. To activate the Calculated PPM mode, select "PPM, Mix Time" or "PPM, Cycle Time" in the wizard section.
Note when you are in Calculated PPM mode ORP will not be displayed on any screens . See page 78 for PPM Cycle time
menu tree .
The AKCOLOR is a colorimetric method chlorine analyzer designed to work in conjunction with most Acu-Trol
Controllers . The AKColor is capable of measuring the amount of free chlorine present in a body of water . The colormetric
method of measuring PPM is superior to other methods because it is much less sensitive to varying water conditions,
including pH and salinity . The information gathered by the AK Color can be used to control chemical feed pumps and
signal alarm conditions . For more information on the AKColor please see Navigation Screen on page 128 or consult your
AKCOLOR installation manual .
The AK10K sensor can be installed to measure/display temperature . The sensor should be installed as close as possible
to where the water comes from the pool . If a temperature probe is installed in the AK1200 flow cell there will be a
temperature variation due to the long tubes and the temperature in the pump room . A common place to install it is in the
small plugged hole in the bottom of the main pump strainer basket .
The sensor uses a special ¼" NPT fitting to hold the stainless steel sensor . A hole should be drilled (7/16") and tapped
(1/4") where the water enters the pump room through a fitting to get double the depth to hold the sensor . If installed
outdoors make sure to keep it out of direct sunlight . Route the wires into the Controller through a strain relief and
connect to the temperature input . The red wire goes to T and the black wire to GND .
The Controller has the capability of measuring two flow switches in which one or both can be a digital flow sensor .
These inputs are general purpose and can measure any dry contact switch state . This can include flow, pressure,
temperature, digital flow rate and so on .
The typical uses for the flow switches are:
Switch 1: Typically used to indicate flow through the flow cell and it is OK to feed chemicals . If a digital sensor is
used the actual flow rate can be measured and displayed in gallons/liters per hour .
Switch 2: Can be used to measure water level for automatic level control . If a digital sensor is used the actual
flow can be measured and displayed in gallons / liters per hour .
To obtain liters per minute the scale factor must be changed to pulses per liter.
