PRELIMINARY 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 or the nearest Hanna Customer Service Center immediately.
Note Save all packing materials until you are sure that the instru-
ment functions correctly. Any damaged or defective items must be returned in their original packing materials together with the supplied accessories.
GENERAL DESCRIPTION
HI 700 and HI 710 series are real time microprocessor­based EC or TDS controllers. They provide accurate measurements, flexible ON/OFF or proportional control ca­pabilities, analog input and output, RS485 port, dual setpoint and alarm signal.
The system is composed of a case inside which the signal conversion circuitry, the microprocessor circuitry and the output power drivers are contained.
MAIN FEATURES OF DIFFERENT MODELS
• Display: large LCD with 4 ½ 17 mm digits and 3 ½ 10 mm digits.
• LEDs: four LEDs are provided for signaling the energizing of relay 1 and 2 (yellow LEDs) and alarm relays (a green and a red LED).
• Relays: 1 or 2 output relays for low conductivity or high conductivity dosage (COM, NO and NC contacts) and 1 output relay for alarm condition (COM, NO and NC con­tacts).
• RS485 isolated communication link (HI 700222 and HI 710222 only).
• Calibration and Setup procedures allowed only through an unlock password.
• Calibration: 2 points with Hanna EC and TDS calibration solutions.
• Four different EC working ranges (0 to 199.9μS; 0 to 1999μS; 0 to 19.99mS; 0 to 199.9mS).
• Four different TDS working ranges (0 to 100.0ppm; 0 to 1000ppm; 0 to 10.00ppm; 0 to 100.0ppm) for HI 710 models.
• Possibility to switch to TDS measurements with conversion factor from 0.00 to 1.00 (HI 710 models only).
• Temperature compensation of the HANNA standard solu­tions.
• Temperature compensation of the EC and TDS reading with temperature coefficient ß selectable from 0 to 10%/°C.
• Manual temperature setting when the temperature probe is not inserted or temperature exceeds the upper range.
• Last calibration data internally recorded (non-volatile EE­PROM memory): calibration date and time, cell constant, calibration solution values.
• Input: 4-ring EC/TDS probe with cell constant 2.0 ± 10%, or 4-20mA analog input from a transmitter.
• Output (HI 700221 and HI 710221 only):

HI 700 and HI 710 series offer a multitude of possibilities, from single and dual set­points to ON/OFF or PID dosage, isolated outputs with user-select­able zoom, bi-directional RS485, recorder outputs in mAmps and Volts.
Use the 3-wire Pt 100 temperature sensor to compensate for the cable resistance and have a precise auto­matic temperature compensation of the measurements in long distance applications.
See the diagram for a recommended installa­tion.
* Note: actual TDS range for HI 710 models depends on TDS factor set.

Power Supply: Connect a 3-wire power cable to the terminal strip, while paying attention to the correct live (L), earth (PE) and neu­tral (N) terminal connections.
Power: 115 Vac -100 mA / 230 Vac - 50 mA.
Live Contact: fused inside 400 mA. PE leakage current 1 mA; this contact must be con-
nected to ground.
Conductivity input: the default input is from conductivity probe. Connect the EC probe to the terminals #10 on page 7. Connect the cable shield to pin 1, and the other four wires according to the following table:
Color Pin # GREEN 2 WHITE 3 RED 4 BLUE 5
Pt 100 Terminals: these contacts (#9 on page 7) connect the Pt 100 temperature sensor for automatic temperature compensation of measurement. The HI7639 EC/TDS probe has a built-in 3-wire Pt 100 sensor to be connected ac­cording to the following table:
Color Pin # GRAY 6 BROWN 7 YELLOW 8.
If using a different Pt 100, separated from the conductivity probe, connect the cable shield to pin 9, and the other wires as explained below.
In the case of a 2-wire sensor connect the Pt 100 to pins 6 and 8, and short pins 7 and 8 with a jumper wire.
If the Pt 100 has more than 2 wires, con­nect the two wires of one end to pins 7 and 8 (pin 7 is an auxiliary input to com­pensate for the cable resistance) and one wire from the other end to pin 6. Leave the fourth wire unconnected, if present.
Note If the meter does not detect the temperature probe, it will
switch automatically to manual temperature compensation with the temperature adjustable through the up and down arrow keys. The “°C” symbol will blink on the LCD.
Note All external cables to be connected to the rear panel should
be ended with cable lugs.
• Analog output: Connect an external recorder with a 2-wire cable to these terminals (#2 on page 7) paying attention to the correct polarity. A wide variety of output signals, either in V or in mA, is available to fit most standards.
• Contact 1 and 2: Connect the dosing devices to these terminals (#5 and #8 on page 7) in order to activate and deactivate them according to the selected control param­eters.
• mA Input: to switch to mA input signal from a conductivity transmitter (e.g. HI8936, HI98143 or HI98144 series) see setup procedure (code
6). Connect the two signal wires from the trans­mitter to terminals #12 on page 7, paying at­tention to the correct polarity.
An unregulated 10 to 30 VDC - 50 mA max. power supply output (#11 on page 7) is pro­vided to power the transmitter, if needed.
Once the installation is completed, select the appropriate working range, the reference temperature (20 or 25°C) and perform conductivity or TDS calibration as described in this instruction manual. Set the control parameters according to the process.

SETUP MODE
HI 700 and HI 710 offer a multitude of possibilities from ON/OFF or PID dosage to analog recorder output and from alarm to selftest features.
The Setup Mode allows the user to set all needed character­istics of the meter.
The setup mode is entered by pressing SETUP and entering the password when the device is in idle or control mode.
Generally speaking, if the password is not inserted the user can only view the setup parameters (except for password) without modifying them (and the device remains in control mode). An exception is certain setup items, or flags, which can activate special tasks when set and confirmed.
Each setup parameter (or setup item) is assigned a two-digit setup code which is entered and displayed on the secondary LCD.
The setup codes can be selected after password and CFM are pressed. When CFM is pressed, the current setup item is saved on EEPROM and the following item is displayed. Whenever LCD is pressed, the de­vice reverts back to control mode. The same is true when CFM is pressed on the last setup item.
The possible transitions in setup mode are the following:
• Then confirm the displayed digit with and move to the next one.
• When the whole password has been inserted, press CFM to confirm it.
Note The default password is set at “0000”.
• The LCD will display “SET” on the upper part and “c.00” on the lower, allowing the user to edit setup param­eters (see table below).
• Enter the code of the parameter you want to set, using the arrow keys as per the password procedure above (e.g. 41).
• Confirm the code by pressing CFM and the default or the previously memorized value will be displayed with the first digit blinking.
Note When the password is not inserted or a wrong password is
confirmed, the display will only show the previously memo­rized value, without blinking (read only mode). In this case, the value cannot be set. Press LCD and start again.
ENTERING THE PASSWORD
• Press SETUP to enter the setup mode. The LCD will display
• Enter the first value of the pass-
“0000” on the upper part and “PAS” on the lower. The first digit of the upper part of the LCD will blink.
• Enter the desired value using the arrow keys and then press CFM.

• After confirmation, the selected parameter is displayed. The user can scroll through the parameters by pressing CFM.

In order to directly set another param­eter, press SETUP again and enter the code or scroll to it by pressing CFM.

Note The process controller automatically checks to ensure that
the entered data matches other related variables. If a wrong configuration is entered, “ERROR” blinks on the LCD to prompt the user. The correct configurations are the following:

Note When a wrong setup value is confirmed,
the controller does not skip to the next setup item but remains in the current item dis­playing a flashing “ERROR” indicator un­til the parameter value is changed by the user (the same is also true for the setup code selection).
Note In some circumstances, the user cannot succeed in setting a
parameter to a desired value if the related parameters are not changed beforehand; e.g. to set a EC high setpoint to 10.0 mS the high alarm must be set to a value greater than 10.0 mS first.
