Display Screen; The Display Screen; Calibrating Temperature; Calibrating Ph - Pentair AK110 Installation And User Manual

The DISPLAY SCREEN shows all the current measurements, as well as the
user programmed set points . It allows access to specific types of information
including the current measurements . Press the arrows on the touch pad to
scroll up or down or left or right as indicated by moving the > Cursor on the
screen .
Calibration: Position the cursor to the left of any of the three measurements
and press ENTER to calibrate that sensor . A value entry screen will then be
opened . Enter the calibrated value with the numeric key pad . To save your
change and exit the value entry screen, press the enter button. To clear a
specific calibration press "0" on the touch pad when the cursor is in front of
the value (The reading may not go to a zero reading but it will default to the
sensors uncalibrated reading) .
Manually turn on relays: The relays in the Controller are represented on the
display screen next to its corresponding sensor reading. Position the cursor
to the left of the status word (either OFF or ON) and press ENTER to toggle
the relay on and off. The length of time the relay is 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 turn back
on immediately .
The temperature sensor is very accurate and should not require calibration . If the calibration is more than a couple
degrees off there may be an installation problem . The most common problems with temperature sensors are listed
below:
1 . The most common temperature problem is the temperature is not the same at the sensor as it is in the main
body of water . It is also possible the temperature error is different depending on the time of day . Make sure the sensor
is not in direct sunlight, and is installed as far into the fitting and as close as possible to the body of water . Evaluate
where the sensor is installed .
2 . The sensor may be damaged . If the sensor is put in a room of 76°F the resistance should be 10,000 OHM's
that can be measured with a standard voltmeter . To calibrate the temperature sensor move the cursor in front of the
temperature reading and press ENTER . Enter the measured value . Press ENTER again to save the calibration change .
Measure the pH using a standard test kit by taking several readings and averaging the results . To calibrate the pH
sensor move the cursor to pH and press
Press ENTER again to save your changes .
