Manual

Thank you for purchasing Suntex products. In order to continuously improve and enhance the transmitter’s
function and capabilities, Suntex reserves the right to modify the content and icon display of the product
without notice. When using this transmitter, please follow all instructions on installation and operation as
described within this manual. Suntex Instruments Co., Ltd. is not liable for any direct or indirect loss or
damages caused by improper usage of this product. If there are any omissions or mistakes, questions or
concerns, regarding the product of this operation manual, please contact our staff. Thank you.
Precautions for Installation
Please read this operation manual thoroughly before installation to prevent incorrect wiring
which may lead to instrument damage and/or safety issues.
•In order to avoid electrical hazards, all wiring must be correctly connected and inspected
before connecting to power supply.
•Meter installation site should be properly ventilated and kept from direct sunlight and high
temperature.
•The signal cable requires a special coaxial cable material. Cables provided by Suntex are
strongly recommended. Please do not use normal electric wires.
•Prevent power surge interference to the transmitter. Especially when using a three-phase
power system, make sure the device is properly grounded. If power surge interference occurs,
separate the power supply of the transmitter from that of the controlled device (i.e. dosing
machines, mixers, etc.), or install surge absorber to reduce power surges from all
electromagnetic switches and power control device coils.
•To protect the instrument, the internal relays must be connected to external power relays
with sufficient ampere capacity before connecting to external alarms or devices. (Please
refer to chapter 3.5 “Electrical Connection Illustration”)
•Suntex logo is shown on the top right corner of the display during all operations. For function
illustration purposes, the logo is not shown in the figures presented in this operation manual.

5.5.2 Calibration Default Values:
Calibration unit: mg/l
Calibration point: No Cal.
Correction factor: 1.0000
Auto return: Auto, 3 minutes
Code settings: OFF
Note: The factory default calibration setting is “No Cal”, and the calibration value is “None”. This means
that the user has not yet calibrated the sensor with the transmitter. After every calibration, the
calibration information display will be updated.

6. Measurement Display Mode
6.1 Text Mode
Text mode is the main measurement screen and shows the measurement value and unit,
temperature compensation mode, temperature measurement and unit, time and date, as seen
in the following illustration.

6.2 Real-Time Chart Mode
Real-time chart mode shows a dynamic change of the measuring values during the last 3 minutes.
Under setting mode, users are allowed to set corresponding Turbidity/SS measuring range (see
section 7.4) to adjust the resolution of the curve. The smaller the range is being set, the higher
resolution the display is. When the unit enters the setup or calibration mode, the real-time
graphic will be re-updated after returning to measurement mode. 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 depicts, each of which
describes a quarter minute (15 seconds).

6.3 Trace Mode
Trace mode features value tracing on a graph with duration configurable from three minutes up
to four weeks. The graph is composed of 60 record sets over time interval T. Each set of data
(T/60) is displayed by calculating the mean, maximum, and minimum value of the previous 60
values. When a new data set is calculated, the set will be displayed on the right and thus shifting
the previous sets to the left by one unit. If time (T) is set for 60 hours, then each displayed set
will represent a calculation of the mean, maximum, and minimum values of the data recorded
during the hour (T/60). The horizontal x-axis of the graph is divided into 12 marks, with each
mark representing T/12, and five data sets between each mark. The user can set the Turbidity/SS
graph range under Mode in Settings (see section 7.4). The smaller the range, the higher the
display resolution. Trace mode shows the real-time measurement value and unit, and temperature
value and unit at the bottom of the screen, as seen in the following illustration.
Attention: If the time interval is reset, the trend in the data will not be retained, and will start a
new trace record.
Note: The time is displayed as (XX: XX) (hr: min); e.g. four weeks (672:00).

6.4 Warning Symbols and Text
1. When detector wiper is activated, the display will show “HOLD” and flash “Wiper Running”. At the
same time, the transmitter will automatically turn off Relay 1 and Relay 2 function. After wiper cleaning
is completed, both Relay 1 and Relay 2 will automatically returns normal status.
2. When the clean function is activated, the display will show “HOLD” and flash “Clean Running”. At the
same time, the WASH indicator LED will light up, and the transmitter will automatically turn off Relay
1 and Relay 2 function. After cleaning is completed, both Relay 1 and Relay 2 will automatically returns
normal status.
3. When Relay 1/Relay 2 Hi settings are activated, the display will flash “REL1-HI/ REL2-HI”, and
RELAY1/RELAY2 indicator LED will light up. hen Relay 1/Relay 2 Lo settings are activated, the
display will flash “REL 1-Lo/ REL 2-Lo”, and the RELAY1/RELAY2 indicator LED will light up.
4. When the Analog current output exceeds the upper/lower limit, the display will flash “mg/l-mA__
/mg/l-mA , or ppm-mA / ppm-mA
Note: The “HOLD” warning text appears when clean function is activated, or when in setup menu, or in
calibration menu. Under HOLD status, the corresponding display and output are as follows:
1. Both Relay 1 and Relay 2 will cease from action. When entering settings menu or calibration
menu under cleaning status, the instrument will automatically halt the cleaning action.
2. The current output corresponding to measurement value remains at the last output value before
HOLD status.
3. The last signal output value from the RS-485 interface is kept at the last output value before
HOLD status.
