SAFETY
Disconnect the main power supply before opening the indicator housing or disassembling
the indicator.
In the process of maintenance, please cut off the source if contacting to any electron, socket
and groupware for fear of getting an electric shock、short current and shattering weight
controller or error movement.
Avoid using the indicator in direct sunlight. The operating ambient temperature range is -10 ~
+40 °C.
Use 100 V ~ 240 V AC
When using AC source wiring, the front line “L” should be connected to weight controller “L”.
The neutral line “N” should be connected to weight controller “N”. “ ” of weight controller
should connected to the ground.
Connect the ground correctly. (Ground impedance < 100 Ω) Avoid connecting the ground
connection with other equipment. The indicator must always be connected to the electrical
ground (earth) for safe operation.
In the industrial surrounding, the main power supply has non-seasonal and short-lived pulse
(high electric current or high voltage) because of high power instrument (start-up and
closedown of the source). Users take necessary actions by themselves to protect weight
controller and other periphery instrument. (Using isolated transformer or restraining
groupware)
The weight installation wiring conforms to standard law in the user’s country.
When installing, keep the indicator away from noise such as high voltage、high current and
high power switches.
The distances of input wiring、output wiring and power wiring are 30 ~ 50 mm. Try to across
vertically if not being separated and avoid being set parallelly.
The diameter of I/O and BCD wiring is 12 AWG ~ 24 AWG. Please select the proper diameter
of the wiring materials. (The length ≦ 10 m)
Set proper resolution for system installation for fear of decreasing the stability and reliability.
When the temperature range is -10 ~ +40 °C and the resolution is over 1 / 3 000, please
select the weight load cell passing C3.
