CALT 4 channel input load cell amplifier junction box

1. Install
Place the junction box in the proper place of the scale. Open the junction box cover, from the junction box of the sensor cable and instrument signal cables through the corresponding interface, all the cable connected and the will after the completion of all of the nut is tightened, don't have to interface with sealing rubber gasket or silly putty plug, screw the nut at the same time.

RJ1: the corresponding adjustment sensor 1 # note: 1, the sensor tag is available for the use of a different number of sensors
RJ2: the corresponding adjustment sensor 2 # will not be the same. When wiring, please refer to the diagram of the weighing device.
RJ3: corresponding adjustment sensor 3 # 2, and all EXE or EXC are the excitation voltage, depending on the manufacturer.
RJ4: corresponding adjustment sensor 4 #

Debug (before adjusting Angle difference apply to full scale heavy truck over and over again)
During the installation and commissioning of the electronic weighing apparatus, it is required to carry out a partial load test on the weighing sensor on the scales. Through corners at balance position (which is actually installed weighing sensor position just above) placed a third of the rated load, record the maximum and the minimum of each Angle and then add averaged. Instrument display within 3 degree value of error, can through the junction box on the potentiometer to adjust to the tolerance range, adjust each weighing sensor corresponding potentiometer and average value to make each Angle meter shows "close", so that after three cycles of pressure Angle of debugging, finally to make each partial mount point error tolerance range. If the instrument shows more than three points of error values, by potentiometer compensation is the compensation is not only, should first adjust the height of the sensor, combining potentiometer adjustment, eventually make the mount point error to the tolerance range.
