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.

6.2 Real-Time Chart Mode
14
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
15
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).

9.1 Communication Connection
The transmitter’s RS-485 communication port features electronic isolation
protection, lightning protection, and provides an isolated ground terminal. It is able
to connect using standard twisted pair (segregated, double-stranded) cables. The
positive connection point D+(B) of all devices are connected together with one
strand of the double-stranded twisted-pair cable, and all the negative contacts D-(A)
with the other strand; the isolated wire shield must be connected to the ground
terminal (GND). In the laboratory, a standalone master-slave communication is
relatively simple. Therefore, standard cables can be used. However, for industrial
settings, strict engineering construction requirements must be taken into account for
proper installation. The wiring diagram is as follows:

TC-7310-RS
ID

Note:
1. The transmitter’s RS-485 interface is equipped with a protective ground terminal. When
ommunicating with the RS-485, the ground terminal must be used to eliminate safety risks.
c
2. Use 120 ohm impedance matching resistors at the signal cable terminals (D+(B) and D-(A)) of the
terminal devices to effectively reduce or eliminate signal reflection.
Note: Three common causes of connection failures:
a. Open circuits: the signal cable has an open circuit.
b. Short circuits: there is insufficient insulation between signal cables causing a short circuit.
c. Idle-bus: there is no data transmission in the Controlbus.
The three conditions above can cause an unknown state of the Controlbus voltage, leading to the
receiver receiving unexpected signals. Therefore, in complicated setups like multi-transmitter
connections, the Controlbus requires a terminating resistor to avoid baud rate reflection, in addition
to biasing circuits composed of pull-high and pull-low resistors, and voltage source (VBus). As seen
in the diagram above, make sure the signal cable terminals D+(B) and D-(A) has free voltage in
between to keep the signals complete. Some systems may not be suitable for a fixed resistor and VBus,
therefore users will need to be more aware of the settings. Some equipment parts (RS-485 converters
48
or modules) provide terminating, pull-high, pull-low resistors, and VBus settings. Please refer to the
corresponding operation manuals before installation and connection. For VBus, the standard is 5 V,
for pull-high and pull-low resistors, 1 KΩ, and for terminating resistors, 120 KΩ.
3. Without repeaters, the RS-485 network cannot exceed a maximum of 32 nodes. The maximum
transmission communication distance for RS-485 is up to 1200 meters. For long distance transmission,
it is recommended to use cables that are specifically design for RS-485.
4. When communicating, all equipment within the network should be consistently kept in the same
transfer mode, baud rate, and parity. All devices must be under different addresses to prevent conflicts
within the network communications.
5. The transmitter’s Modbus command can only access 50 registers. Abnormal information will be
returned if the maximum length is exceeded.
6. The idle time in which a slave instrument responds to a master machine is different according to
each model. Generally, the time needed should be longer than 0.5 seconds (some models may
require a longer waiting-responding time, please note if the operation manual specifies).
9.2 MODBUS Name and Address Table
49
Modbus response table is as follows. As users communicate with transmitters through PLC or Manmachine Interface, check to see if the transmission of address subtracts 1 by default. If so, add 1 onto
each address to match the table; e.g. for Turbidity/SS measurement logic address 0035H (16-bit) or 53
(10-bit), if the output signal is subtracted by 1 by the PLC or Man-machine Interface, users must input
0036H (16-bit) or 54 (10-bit) to match the appropriate logic address.

9.2 MODBUS Name and Address Table
53
Modbus response table is as follows. As users communicate with transmitters through PLC or Manmachine Interface, check to see if the transmission of address subtracts 1 by default. If so, add 1 onto
each address to match the table; e.g. for Turbidity/SS measurement logic address 0035H (16-bit) or 53
(10-bit), if the output signal is subtracted by 1 by the PLC or Man-machine Interface, users must input
0036H (16-bit) or 54 (10-bit) to match the appropriate logic address.

9.3 Modbus Description Example (e.g.: Function Code 03H)
57
he
following description uses Turbidity/SS reading 0035H as an example. If the
T
Turbidity/SS measured value is 25.10 NTU, confirm that the host and sub-machine
communication format settings are correct. The host sends request commands
according to the left column of the table below, then receives a corresponding response
from the sub-machine according to the right column. This example shows the function
code 03H as transmission data format; for other function codes, the same logic applies.

Note: FLOAT is a 32-bit IEEE 754 format. The above table is divided into two 16-bit
register data transfers. The back 16-bit register (CC CD) is transferred first, followed
by the front 16-bit register (41 C8). Every 16-bit format is high-bit in the front and
low-bit in the post. For example, if the Turbidity/SS reading is now 25.10 NTU, the
16-bit of FLOAT data (hexadecimal) is 41 C8 CC CD. However, the transmission
order will be CC CD 41 C8.
