English 2.0 IMPORTANT - Bluelab pH Probe care pH probes DO NOT last forever. They age through normal use and will eventually fail. The life time of a pH probe depends on the environment it is used in and the way that it is treated. To receive a long life from your Bluelab pH Probe, please ensure you follow the guide below. pH probes contain glass and are therefore FRAGILE. With good care, they will give a long service life.
3.0 English 1 2 Installing the pH controller Select a suitable location that is: • Less than 5.65 feet / 2 meters from your reservoir. The probes must be immersed in solution at all times. • Less than 4.9 feet / 1.5 meters from an electrical mains outlet. • Less than 5.56 feet / 2 meters from pH Up or Down solution. The inlet tube must reach the bottom of the container. • At a suitable height to see the display and for easy operation (recommend slightly below eye level when standing).
.0 English 1 Set up inlet dosing tube To straighten tube: Bend tube in the opposite direction and straighten by running through closed fingers. Inlet ‘’ arrow on pump cover 2 Insert one end of the dosing tube with connector into the LEFT peristaltic pump tube. This is the ‘inlet dosing tube’. Left pump tube Connector 3 Ensure the inlet dosing tube will reach the bottom of the pH stock solution container.
English 9.0 Connect power adaptor 1 Select and connect the appropriate mains plug adaptor for your country to the power supply unit. 2 Connect the power adaptor into the base of the pH controller where ‘PWR’ is labelled. Plug the adaptor into mains power supply. 3 Switch on power adaptor at the mains. The pH controller will complete a display test sequence. 4 The default setting, when the unit is first powered up, is ‘monitoring’ mode.
11.0 1 The pH controller is set to the following values by default: • • • • • • • English Factory settings Mode Monitor Set pH 5.8 Alarm On HighAlarm 6.5 LowAlarm 5.6 Dose Up/Dn Down/Acid OnTime 1Sec • • • • • • • OffTime 10Min Backlight 100% On Contrast 16 2/3pt Cal 2 EarthLink Off Language eng pH Calibration none Note: ‘Pump runtime’ [HH:MM:SS] is the time the pump has dosed for. ‘Product runtime’ [Hrs] is the duration of time the pH controller has been in use for.
13.0 pH calibration English pH calibration is important before first use. It ensures pH measurements and/or pH stock solution dosing is accurate. The Bluelab Temperature Probe DOES NOT require calibration. For accurate pH readings the pH probe is cleaned and recalibrated when: • It has been 30 days since the last pH calibration, and the successful calibration indicators are not showing. • The reading is different to what you were expecting. • The pH controller is reset to factory default.
13.0 pH calibration cont. English To calibrate the pH 1 Clean pH probe tip. See section 24.0 (the pH probe does not require cleaning before the first use). 2 The calibration default is set at two point calibration. If a three point calibration is required: a) Press ‘menu’. b) Press ‘∨’ to find ‘2/3 point cal’. Press ‘enter’. c) Press ‘∨’ to select ‘3’. Press ‘enter’. When ‘saved’ is displayed on screen, three point calibration is now available.
English 14.0 The tip of the Bluelab pH Probe must be submerged in the liquid for a measurement to occur. It is optional to use the Bluelab Temperature Probe, but required for automatic temperature compensation (ATC) to occur, or to enable ‘Earthlink’. • Do not pour concentrated nutrient solution or pH adjuster directly onto probes when in the reservoir.
English 17.0 Set the dosing OnTime and OffTime A dosing cycle includes the OnTime and the OffTime that the peristaltic pump doses the system for. The arrow symbol on the display will flash during the dose cycle. Adjustments for OnTime and OffTime will be required so that three dosing cycles only change the pH value by 0.1 pH. • ‘OnTime’ is the length of time the peristaltic pump will dose for. The ‘OnTime’ can be set from 1 to 60 seconds. • ‘OffTime’ is the delay time between each dose.
English 18.0 Set alarms (optional) The alarm function alerts you when the solution deviates too far from the desired pH. When an alarm condition is present, the pH value and the alarm symbol will flash on the screen. This is an ‘alarm lockout’ state. All dosing will stop. If the measurement changes back to within the limits you have chosen, the flashing will stop and dosing will start. To set the ‘High Alarm’ value: 1 Press ‘menu’. 2 Press ‘∨’ to select ‘Alarm High’. Press ‘enter’.
English 20.0 Priming the pump / manual dosing ‘Pump Ovrde’ allows you to fill the inlet and outlet tubes with dosing solution before first use (removing any air in the tubes), and to manually dose the tank if required. Always ensure the inlet dosing tube reaches to the bottom of the pH stock solution container. Ensure the outlet dosing tube is above the highest water line so that pH stock solution drips into the tank/reservoir.
English 22.0 Change the screen backlight and/or contrast These can be adjusted to best suit the light levels of the environment the pH controller is being used in. Backlight can be set at 0%, 25%, 50%, 75% or 100%. Contrast can be set between 0 and 30. To change the screen backlight: 1 Press ‘menu’. 2 Press ‘∨’ to find ‘Backlight’. Press ‘enter’. 3 Press ‘∨’ or ‘∧’ to select the desired value. Press ‘enter’ to save, then ‘menu’ to exit back to the main display.
English 24.0 Cleaning the Bluelab pH Probe 17 To ensure accurate readings the pH probe tip needs to be rinsed in water and cleaned prior to calibration using the following instructions. After cleaning, use the probe straight away, or place the storage cap on the probe tip. Always ensure the cap contains enough Bluelab pH Probe KCl Storage Solution to cover the probe tip. 1 Remove storage cap from pH probe. Hold the top of the storage cap, twist the cap to loosen then remove.
25.0 Troubleshooting guide English Trouble pH reading inaccurate Display shows ‘Failed ’ during calibration No display Reason Correction pH probe not plugged in. Connect pH probe. Check pH probe connection. Using factory default calibration. Calibrate pH probe. Contaminated pH probe / glassware not clean. Clean pH probe, then calibrate. Calibration old. Calibrate pH probe. Broken glass bulb, tube or connector. Replace pH probe. pH probe damaged or old. Replace pH probe.
English 26.0 Frequently asked questions Question Answer Why is the ‘’ or ‘’ flashing but the pump is not turning? The ‘’ or ‘’ will flash when ever the pH controller is in a dose cycle. This includes the ‘OnTime’ and ‘OffTime’. The pump does not turn during the ‘OffTime’. What are dosing lockouts? A feature that stops the pH controller from dosing if: • The temperature probe measures a solution temperature of less than 0 °C / 32 °F or more than 50 °C / 122 °F.
