Precautionsforinstallation
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 controller before wiring input, output connections,
and remove it before opening the controller housing.
zThe installation site of the controller 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.
zThe internal relay contact of the instruments is for alarm or control function. Due to safety,
please must connect to external relay which can stand enough ampere to make sure the safety
operation of the instruments.（Please refer to chapter 3.7“Illustration of electrical
connection＂）

3.4 Installation of transmitter PH-300T: (alternative equipment)
PH-300T transmitter is mainly installed on the electrode protective pipe, but also can apply
wall mounting and pipe mounting. For long distance transmission (100m), if PC-3110 is more
than 30m far away from the electrode, PH-300T transmitter is recommended to avoid the
attenuation of electrode signal, and for the convenience of onsite observation, measurement,
and calibration.
3.5 Connection of transmitter PC-3110 and transmitter PH-300T:
A. Connect the GLASS point of transmitter PH-300T’s terminal to the electrode coaxial inner.
(Note: Remove the black conductive rubber); connect the REF point of transmitter
PH-300T’s terminal to the electrode coaxial shield.
B. See the two-wire distributing system and three-wire distributing system in the following
page.
C. Sign “PT-1000” on transmitter PH-300T’s terminal is the connector for automatic
temperature compensation probe, PT-1000, or applies a fixed temperature compensation
resistance.
D. The V+ and V- of transmitter PH-300T’s terminal respectively connect to DC12V+ and –
of the controller.
E. The S+ and S- on transmitter PH-300T’s terminal respectively connect to GLASS and REF
of the controller.
F. The I+ and I- on transmitter PH-300T’s terminal are output (4-20mA), which can connect
to devices that receive current signals. (Note: The current output signal of this
transmitter is not insulating, so use it with much care!)

calibration, the operation applies multi-keys, and coding protection if necessary. Description of
the key functions is in the following:
：In the parameter set-up mode, pressing this key allows you exit parameter set-up mode
and back to Measurement mode.
:In the Calibration mode, pressing this key allows you exit Calibration mode and back to
Measurement mode.

4.4 Display:
Note: 1. When the wash device is turned on, the display shows and twinkles the description, “Clean
Running”. At the same time, the ACT indicator LED lights up, and the transmitter
automatically turns off Relay 1 and Relay 2 function. After finishing cleaning, the Relay 1
and Relay 2 will automatically back to normal status.
2. When Relay 1/ Relay 2 which is set in high setting point is in action, the display shows and
twinkles the description, “REL 1_Hi/ Relay 2_Hi”, and ACT indicator LED lights up. When
Relay 1/ Relay 2 which is set in low setting point is in action, the display shows and twinkles
the description, “REL 1_Lo/ Relay 2_Lo”, and ACT indicator LED lights up.
3. When Analog 1 current output exceeds the upper/lower setting range, the display shows and
twinkles the symbol ”pH-mA▲/ pH-mA▼” or ”ORP-mA▲/ ORP-mA▼”. When Analog
2 current output exceeds the upper/lower setting range, the display shows and twinkles the
symbol ” °C-mA▲/ °C -mA▼”.
4. When PID using Relay 1/Analog 2 as Direct control, the display twinkles the description:
“REL1-Lo/ pH(ORP)-mA▼; When PID using Relay 2/Analog 2 as Reverse control, the
