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 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 3.6ʳ“Illustration of electrical
connectionϙ˅

4.2 Keypad:
In order to prevent inappropriate operation by others, before the parameter setting and
calibration, the operation applies multi-keysʿʳand coding protection if necessary. Description of
the key functions is in the following:
ΚIn the parameter set-up mode, pressing this key allows you exit parameter set-up mode
and back to Measurement mode.
ˍIn the Calibration mode, pressing this key allows you exit Calibration mode and back to
Measurement mode.
Κ1. In the parameter set-up mode and Calibration mode, pressing this key to select
leftward or change to another page.
2. When adjusting value, press this key to increase the value.
Κ1. In the parameter set-up mode and Calibration mode, pressing this key to select
rightward or change to another page.
2. When adjusting value, press this key to decrease the value.
ΚKey for confirmation; pressing this key is essential when modifying data value or
selecting the parameter setting items in the window.

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 which is set in high setting point is in action, the display shows and twinkles
the description, “REL 1_Hi”, and ACT indicator LED lights up. When Relay 1 which is set
in low setting point is in action, the display shows and twinkles the description, “REL 1_Lo”,
and ACT indicator LED lights up.
3.When Relay 2 which is set in high setting point is in action, the display shows and twinkles
the description, “REL 2_Hi”, and ACT indicator LED lights up. When Relay 2 which is set
in low setting point is in action, the display shows and twinkles the description, “REL 2_Lo”,
and ACT indicator LED lights up.
4. When under measurement mode, if the temperature compensation mode is set in MTC
(Manual adjustment), press or to adjust the MTC temperature manual.
