Wrong wiring will lead to breakdown or electrical shock of the instrument, please read this
operation manual clearly before installation.
z Make sure to remove AC power from the transmitter before wiring input, output connections,
and remove it before opening the transmitter housing.
z The installation site of the transmitter should be good in ventilation and avoid direct
sunshine.
z The material of signal cable should be special coaxial cable. Strongly recommend using our
coaxial cable. Do not use normal wires instead.
z Avoid electrical surge when using power. Especially when using three-phase power, use
ground wire correctly.
z The 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 4.5“Illustration of
electrical connection”)
3. Assembly and installation
3.1 T ransmitter installation: This transmitter can be installed through panel mounting,
wall mounting and pipe mounting.
Installation of panel mounting: First, prepare a square hole of 138 x 138mm on the panel box,
and then insert the transmitter directly into the panel box. Insert the accessorial mounting
bracket from the rear, and make it be fixed in to pickup groove.

5.2 Keypad:
In order to prevent inappropriate operation by others, before the parameter setting and
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.
In the parameter set-up mode and Calibration mode, pressing this key to
increase the value or to scroll to other function.
In the parameter set-up mode and Calibration mode, pressing this key to
decrease the value or to scroll to other function.
: Key for confirmation; pressing this key is essential when modifying data value
or selecting the parameter setting items in the window.
: In the Measurement mode, pressing these two keys simultaneously
allows you enter Calibration mode.
: In the Measurement mode, pressing these two keys simultaneously
allows you enter parameter set-up mode.

5.3 LED indicators:
WASH: Washing device operation indicator lamp; when the washing device is started up,
the Alarm indicator will light.
HI : Controlling operation indicator lamp; when the high setting point is reached, the
REL1 indicator will light.
LO : Controlling operation indicator lamp; when the low setting point is started up, the
REL2 indicator will light.
B.L. : Light sensor; in the automatic display backlit mode, the lamp will light or go out
as the change of environmental brightness.
