Thank you for purchasing Suntex products. In order to continually improve and enhance the transmitter’s function, Suntex reserves the right to modify the content and icon display of the product. The actual situation is subject to the instrument without notice. The operation manual is only provided for function and installation description, Suntex Instruments Co., Ltd. is not liable for any person or entity for any direct or indirect loss or damage due to improper usage of this product. If you have any questions or find omission, negligence or mistakes of the operation manual, please contact with our staff, thank you.

Precautions for installation

Wrong wiring will lead to breakdown or electrical shock of the instrument, please read this operation manual clearly before installation. zMake sure to remove AC power from the transmitter before wiring input, output connections,

and remove it before opening the transmitter’s housing.

zThe installation site of the transmitter should be good in ventilation and avoid direct

sunshine.

zThe material of signal cable should be special coaxial cable. Strongly recommend using our

coaxial cable. Do not use normal wires instead.

zAvoid electrical surge when using power. Especially when using three-phase power, use

ground wire correctly. If the power surges interference occurs, separate the power supply of transmitter from the control device, such as: dosing machines, mixers, etc. to make individual power supply for the transmitter; or set surge absorber to reduce the power surges at all electromagnetic switches and power control device coils.

zThe internal relay contact of the instruments is for alarm or control function. Due to safety,

please must connect to external relays which can stand enough ampere to make sure the safety operation of the instrument.˄Please refer to chapter 3.6ȾIllustration of electrical

connectionȿ˅

zThere a manufacturer logo usually shows in the display of transmitter, and the illustration of

each function in the manual is no longer expressed.

1.3 Measurement principle

1. EC-4110-I/EC-4110-ICON utililze conversion of electric field and magnetic field to measure

the conductivity in a sample solution. Sensor assembly is composed of Drive Coil and Receive Coil, whose induction is not directly contact with sample solution, belonging to inductive type. It is also composed of chemical-resistant materials, for example: the 8-201-PFA-10 is made up of PFA that can be applied to acidic, alkaline, salt solutions, effluents, etc. in online monitoring industrial environments.

2. EC-4110-I/EC-4110-ICON apply alternative signals of electric field to activate drive coil to

produce the magnetic field. After that, sample solution(containing ions in different conc.) turns into a conductive circuit, and then the signal can b e received on receive cell, turned into magnitude of current to measure the conductivity.

3. The temperature probes have three-wiring type PTC1000 and PTC100 and two-wiring type

NTC30K as reference. Users can select the spec according to sensor assembl y. ȾCond.@txȿ which presents conductivity is being measured at actual tmeperature Ⱦtxȿ, is regarded as absolute conductivity. Refer to temperature compensation modes (linear, non-linear, or off)

and reference temperature, “Cond.@tref” is to present conductivity based on desired ref. temperature.

4. EC-4110-I/EC-4110-ICON both have measurement of salinity and TDS.

5. EC-4110-ICON has built-in conc. conversion table including NaCl, HCl, HNO

, NaOH,

2SO4

, H3PO4, etc. Users can select the corresponding solution types and conc. range. When the conc. range is not applicable, there twinkles error message as an alarm during measurement. The absolute conductivity “Cond.@tx” can be turned into concentration of th e sample solution, and with compensation of ref. temperature it also can be treated as “Cond.@tref.”

6. EC-4110-ICON has self-defined conversion table between cond. and conc., and there are conc.

units %, ppm, or ppt as reference.

7. Self-defined table( max. up to 9 temperature data, and there includes 9 corresponding cond.

and conc. at each temp.) (9 x 9 matrix) can be input corresponding conductivity and concentration at the same temperature by users. The temp., cond., and conc. can be individually input in ascendant or descendant order. After that, the unit is going to check the data and correct somewhere the order goes wr ong. When users only have data of cond. and conc. at one kind of temp. for conversion, it is necessary to apply linear temperature compensation to input T.C. value.

8. Due to conductivity attained by electromagnetic induction not by contact type, cell constant is

to perform the geometric structure characteristic of a drive coil and a receive coil, and the signal cable of the sensor is labeled with cell constant made by lab when out of factory. The inductive signals can be influenced by the surroundings environments such as installation pipeline wall effect, metal(conductive) pipeline and plastic(insulation, non-conductive) pipeline, the distance from sensor assembly and the shell of pipeline. After installed, zero-point calibration in air and cell constant calibration are required, and there is no need to change the labeled cell constant since it can use span calibration to make product adjustment in the field directly.

9. It should restart zero-point calibration in air after each installation or maintenance, and the

surface of sensor assembly needs cleaning without any attachment, making it dry, and using cell constant or product adjustment for calibration.

10. The default measuring range is 2000mS/cm, and users can select 2000mS, 999.9mS, 99.99mS,

9.99mS, ȝ6, or AUTO, where AUTO means automatic switch unit.

2. Assembly and installation

2.1 T ransmitter installation:

6.2 Real-Time Chart mode

Real-time chart mode is for dynamic display of real-time graphics. The duration is about three minutes of the recent changes in measured values of the curve. Users can set the mode to its corresponding Cond./Conc. measuring range (see section 7.4). The smaller the range is set, the higher resolution of the display is. When entering setup or calibration mode and returning to measurement mode, the real-time graphic will be re-updated. When the measured value exceeds a set range of the upper and lower limit, the graphics will be presented in the upper and lower limits dotted line. Real-time chart mode display is shown as below. There are also real-time measurement value, & unit, and temperature value & unit which are displayed in the bottom of the screen. The timeline in real-time graphic is divided into 12 depict, which is describe the range of representatives of each of 1 / 4 minutes (15 seconds).

6.3 Trace mode

The feature of the trace mode is the record duration which can be set by the user (range from three minutes, up to four weeks). The trend graphic records the measurements in the past T time. The trend is recorded by the 60 group structure. Hence, each group of units is recorded in T/60 time interval. The trend line is constructed by all value data which is calculated to the average (Mean Value), maximum (Max Value) and minimum (Min Value) form. When the latest T/60 record shows in the rightmost of the trend graphic, all the previous record will be moved to the left side of the graphic. For example, T is set to 60 hours, then each set of records will be calculated to the average, the maximum, the minimum values after one hour(T/60 = 1), each time interval. Timeline of trends which is divided into 12 depictions showed on the horizontal axis of the display is on behalf of each characterization interval T/12. So, every depiction has 5 (T/60) sets of records. Users can set the corresponding Cond./Conc. measuring range in its set-up menu(see section 7.4). The smaller the range is set, the higher resolution of the display is. The trace mode is shown as below. There are also real-time measurement value, & unit, and temperature value & unit which are displayed in the bottom of the screen. Attention: When the time interval has been reset, the trend in the data will not be retained, it will start a new trace record. Note: The time display format (XX: XX) (hr: min), for example, appear as four weeks (672:00).
