PRELIMINARY EXAMINATIONPRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any noticeable damage, notify your Dealer.

Note: Save all packing materials until you are sure that the

instrument functions correctly. Any defective item must be returned in the original packaging together with the supplied accessories.

IMPORTANT:

1. Read the instructions before using the instrument.

2. The instrument should be connected to a mains socket.

3. Never install the controller outdoors, in a wet or humid area or under direct sun light. Nor install the controller where liquids may be sprayed or poured on it.

4. The instrument’s main power line as well as the dosage and alarm terminals are protected by separate 2A fuses. Use only 2A fuses for replacement.

GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

Hanna's wall-mounted conductivity/TDS and pH controllers designed to meet a variety of process control requirements, especially those in horticultural, hydroponics and agricultural applications on the one hand and boilers and cooling towers on the other.

All controllers provide for two separate relays, one for pH and another for Conductivity/TDS. HI 9913 and HI 9935 also come with proportional control to save on use of chemicals and fertilizers.

All models operate with the optional Hanna 4-ring probes to provide a linear and repeatable measurement. The conductivity/TDS probes can be installed quickly and easily. Simply plug the DIN connector into the socket and tighten the retainer ring.

The EC/TDS probes incorporate a temperature sensor and the controllers will automatically compensate for the temperature effect. Accurate measurements are displayed on a large LCD.

Similarly, the pH electrode can be installed quickly and easily. Simply plug the universal BNC connector into the socket and twist it into a secured position. In order to avoid electrical noise and interference, the pH circuitry also provides for a ground probe (differential input).

are

The controllers come equipped with relays operating at a maximum of 2A (240V).

They incorporate a triple contact alarm system. When activated, the alarm contacts will open or close, triggering the mechanism of your choice, whether a buzzer, light or any other electrical device.

The controllers are housed in a rugged, modular, fiber-reinforced ABS housing.

All models can be wired to work with 110/115V or 220/240V at 50/60 Hz power supplies.

Figure 3 is a dimensioned, bottom view of the wall mounted controller. The modular design isolates the control circuitry from the contacts making it possible to make the connections and then close the compartment. Adjustments can then be made only in the control area, without having to open the contacts compartment.
