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. [. . . ] · Before connecting the controller to the mains, wire the controller completely and make all the connections for pumps, alarm, probe, set the alarm threshold and adjust the settings. Upon completion replace the cover Only then cover. connect the controller to the power supply. PROBE CONNECTION DIN connector WIRING ACCESS PORTS · Attach the conductivity/TDS probe (HI 3002, HI 3001D or HI 7638) to the DIN socket located on the bottom of the casing. Align the guide on the connector with the socket, push the connector in and tighten the retainer ring. (HI 3002 is more suitable for direct immersion in the tank, vat or pipes. HI 3001D can be mounted directly into a pipe and HI 7638 is recommended for high temperature and pressure applications). · The probes incorporate a temperature sensor and the controller's circuitry automatically compensates for the temperature effect. RELAY CONNECTIONS · Wire the external devices (pumps or electrovalves) directly to the relay terminal strips of the controller (see 17 - Functional Dia- 12 gram). The terminals are powered and hence you do not need an external power supply for the pumps or valves.

If the actual mea0/20 4/20 0/20 surements are above the setpoint by a mA OUTPUT 4/20OUTPUT mA margin greater than the user-selectable alarm threshold, the alarm terminal is activated. Likewise, when HI 9934 measures 1500 ppm (mg/L), the output values are 15 mA or 16 mA based on whether the 0-20 or 4-20 output was selected.

You however do not need to worry about having to compensate for this or go through complicated calculations since all three probes recommended in this manual (HI 7638, HI 3002 and HI 3001D) compensate for temperature automatically. 14 MAIN POWER SUPPLY CONNECTION · Before connecting the unit to the mains make sure mains, that the controller is completely wired and that all connections for pump, alarm, probe, etc. · For 220-240V, short the L1 and N1 terminals. Then wire the external power supply to the three terminals as shown. 220 VAC Configuration Neutral Line POWER SUPPLY L L1 N1 · 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 NORMAL OPERATION & MEASUREMENT Make sure that the controller has been properly calibrated before commencing and that the conductivity/TDS setpoint has been adjusted (see following pages). The conductivity/TDS probe must be properly connected and wired to the controller (see preceding pages). The protective sleeve must not be removed and the holes on the sleeve should be near the top (the cable end). The probe must be immersed in the solution above the air-vent holes on the external sleeve. The probe must be installed in such a way as to minimize presence of air bubbles (see probe installation tips at the end of the SET manual). [. . . ] For larger pipe sizes, HI 3001D can be mounted upside down or vertically. 1/2" Thread 21 HI 3002 FOR IN-LINE INSTALLATION The drawing illustrates the ideal installation system since the stream pressure in the pipe forces the air bubbles out automatically. HI 3001D illustrated previously can also be , mounted in this fashion. However the longer stem of HI 3002 facilitates an easier escape route for any air bubbles. HI 3002 comes with external 1/2" NPT and thread 60 mm (2. 4") immersion level. HI 3002 > 1/2" GAS HI 7638 FOR IN-LINE INSTALLATION HI 7638 comes with stainless steel 3/8" NPT external thread and 60 mm (2. 4") immersion level. [. . . ]
