★ Note: The length of the connecting cable between the probe and the host of the split-type ultrasonic
level meter should be determined in advance. Do not go to the site and connect with other cables.
Connecting the cable again in the field will affect the signal transmission quality and strength.
4.4 Electrical wiring diagram
★ When connecting the power, do not connect the AC power to any other terminal except the AC
power terminal. Otherwise it will burn the instrument circuit or components.
★ The cable connecting the sensor and the host cannot be in the same trunk with any AC power. If it
cannot be avoided in the same trunk, the sensor cable must be protected by a metal tube to
completely shield electromagnetic interference from AC power.

★ 485, 232, and 4-20ma output terminals cannot be short-circuited. If the short-circuit occurs, the
internal circuit will burn out.
