Please read this instruction manual carefully before using the instrument. This manual will provide you with the necessary information for a correct use of the instrument, as well as a more precise idea of its versatility. [. . . ] Then manually set the temperature by turning the dial (see 10 - Functional Diagram) to the correct working temperature. 20 10 0 -10 30 40 50 60 70 80 MTC ATC MTC °C Temp. compensation selector · Automatic Temperature Compensation: Move the selector to the ATC position (see 17-Functional Diagram). Then wire a Pt 100 probe such as HI 5001/5 to the controller's terminals as shown. Pt 100 1-grey Pt 100 2-brown Pt 100 3-yellow Pt 100 shield 1-grey 2-brown 3-yellow shield HI 5001/5 is made of stainless steel. For solutions not compatible with stainless steel, use the glassbody HI 5002/5 or other appropriate 3-wire Pt 100 probe. 1 MAIN POWER SUPPLY CONNECTION 3 2 · Before connecting the unit to the mains make sure mains, that the controller is completely wired and that all connections for pump, alarm, electrode, etc. · For 220-240V, short the L1 and N1 terminals. Then wire the external power supply to the three terminals as shown. L L1 N1 POWER SUPPLY 220 VAC Configuration Neutral Line · For 110-115V, short the L and L1 terminals and the N1 and Neutral. Then wire the external power supply to the three terminals as shown. · Replace the cover with the gasket and screw it tight with the 4 screws provided. Only then connect the controller to the mains. 110 VAC Configuration 110 VAC Configuration Neutral Line POWER SUPPLY L L1 N1 18 NORMAL OPERATION and MEASUREMENT Make sure that the controller has been properly calibrated before commencing and that the pH or ORP setpoint(s) have been adjusted (see the following pages). The pH or ORP electrodes and any ground probes must be properly connected and wired to the controller (see preceding pages). Remove the protecteive cap if it is still on the tip of the electrode. SET Ensure that the electrode is properly installed and lies permanently in the solution to a depth of at least 4cm/1. 5". The selector (see 7 - Functional Diagram) must be on the "READ" READ position. If temperature compensation is necessary (HI 9910 and HI 9911), make sure that the temperature probe is also immersed in the solution and the selector is on ATC (see 17 - Functional Diagram). ATC For manual temperature compensation, the se- MTC lector should be on MTC with the dial showing the temperature of the solution. MTC ATC 20 10 0 -10 30 40 50 60 70 80 MTC °C The actual pH or ORP value of the solution will be displayed on the LCD. SET 8. 00 READ All controllers provide for a visual dosing status through an LED. With HI 9910 and HI 9920 the DOSING LED lights up when the controller is in the pH or ORP dosage mode and the terminals are activated. Likewise, HI 9911 provides for two LED's, one for ACID and another for ALK (alkaline) dosage when the appropriate terminals are activated. 19 DOSING ACID FEED ALK pH CALIBRATION (HI 9910 and HI 9911) Make sure that the pH electrode and any ground probe have been properly connected and wired to the controller (see preceding pages) and that the meter is plugged to the mains. Calibration should be ideally performed at a temperature similar to that of the liquid to be monitored. Use a Checktemp (or an accurate thermometer) as reference for temperature compensation. Remove the electrode cap if it is still on the electrode. HI 7007 4 cm (1½") During calibration, move the electrode and the separate ground probe (if in use) together from one buffer to the next. 4 cm (1½") HI 7007 If no separate ground probe is being used, make sure that the Reference and the Matching Pin terminals are shorted (see 14 - Functional Diagram). If the electrode incorporates a ground probe/matching pin (HI 1003/3) then remove the jumper. SET · Turn the switch to the "READ" position. OFFSET ADJUSTMENT: READ · Rinse the tip of the electrode with pH 7. 01 solution (HI 7007), then dip the bottom 4 cm (1. 5") of the electrode (and ground probe) in the pH 7. 01 buffer. [. . . ] You can now connect your meter directly to an AmpHel electrode, saving the cost of a transmitter. The standard cable length of the AmpHel electrode is 5 m (16. 5'). Additional lengths of regular cable up to 50 m (165'), can be installed without special connectors. It is recommended to use coaxial cables due to their excellent insulation, even though, Amphel electrodes can operate with both. [. . . ]
