Manual

Thank you for purchasing Suntex products. In order to continuously improve and enhance the transmitter’s
function and capabilities, Suntex reserves the right to modify the content and icon display of the product
without notice. When using this transmitter, please follow all instructions on installation and operation as
described within this manual. Suntex Instruments Co., Ltd. is not liable for any direct or indirect loss or
damages caused by improper usage of this product. If there are any omissions or mistakes, questions or
concerns, regarding the product of this operation manual, please contact our staff. Thank you.
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.
