Main Control Panel

The components of main control panel are installed on the
rear of the upper cabinet door panel, which is convenient for
user operation. It consists of a core board, an expansion
board and a display screen. The main control panel supports
touch control. The components of main control panel are
connected to the measurement interface drive panel via
RS485 (J8) cable.
Relevant wiring of the main control panel is shown in the
following figure:

Safety Wiring
• Only trained or authorized technicians are allowed to carry
out electrical wiring and maintenance. Proper operation is
required to avoid ESD (electrostatic discharge), otherwise
the electronic components inside the circuit board will be
damaged due to electrostatic breakdown. Be careful,
measures shall be taken, and ESD shall be grounded.
• It is suggested that technicians shall release static electricity
on their body before touching any electronic components
(such as the PCB board and its components). For example,
by touching the instrument housing, metal conduit, and
water tube with hands.
Notices before Wiring
• Make sure the power cord is not powered on before
connecting the power supply to the instrument.
• Cut off the power supply previously connected to the relay;

Installation
• Lead the live wire, neutral wire and ground wire to the
power supply terminal in the instrument electrical box, and
pay attention to the position of the fuse;
• Insert the wire into the corresponding wiring terminal and
tighten the screw;
• All connections must conform to local safety standards.
Notices during Wiring
• Make sure that the instrument is not powered on when
conducting wiring operations;
• Strip off a 6 mm insulation layer of each cable;
• Insert the metal wire after stripping off the insulation layer
into the wiring terminal, and tighten the screw. The
maximum torque for tightening the screw shall not exceed
0.6 nm, meanwhile the maximum pulling force shall not
exceed 20 N;
• The isolation design is applied to the external RS485 and
0/4 - 20 mA interfaces;
• Maximum switching capacity of relay contacts: 250 V / 2 A
(resistive load).
WARNING: The instrument is not equipped
with a power switch, so the power switch
with the functions similar to that of a breaker
should comply with local safety standards
and must be prepared before final installation.
The circuit breaker must be as close to the
instrument as possible and convenient to be
controlled by the operator. When the
instrument is powered off, there must be a
clear and explicit indication.
All conductors need to have a temperature
resistance of at least 75°C.
Do not power on the instrument until all
preparation work (including reagent
installation, water sample access, etc. is
completed.
