3. OPERATION 3.1 GENERAL RULES Do not install the CB900K in direct sunshine, and avoid sudden temperature changes, vibration or wind. Best performance is achieved when temperature is about 20�or 68�and the relative humidity is about 50%. Ground the CB900K via the power cable to the rear terminal and ensure a good ground connection. Do not ground directly to other equipment. Analog input/output signals are sensitive to electrical noise. Do not bind these cables together as it could result in cross-talk interference. Please also keep them well away from AC power cable, and keep all cable as short as possible. If the local AC electrical supply fluctuates by more than�10% an AC regulator must be used in order to stabilize the power and reduce power spikes. 3.2 INPUT SENSITIVITY OF LOAD CELL The input sensitivity (A) of load cell can be calculated from the following formula: A = (Load cell output voltage at scale capacity - Load cell output voltage at dead

load) × Step width / Scale capacity CB900K requires that “A” must be greater than or equal to 0.5�V/d.


3.3 CONNECTING THE LOAD CELL TO THE INDICATOR The analog output from the Load Cell and the RS232 input/output signals are sensitive to electrical noise. Do not bind these cables together as it could result in cross-talk interference. Please also keep them well away from the AC power cables.

7.6 SPEED INPUT TYPE Press “0”, “1” or “2” key to select the speed input type. 0 = PULSE (photo-couple 5V, 1mA; pulse input board AC/DC 24V, 1mA) 1 = VOLTAGE 2 = CURRENT


7.6.1 Input type is pulse Press “0” key to select the pulse input type.

Press “E” key to accept and modify the corresponding parameter.

Speed calibration: Single pulse length is set by the total length of belt(L), number of loop (n) and the number of pulse generated during the running period (p), and record to the EERROM.

Calibration condition: a) Set the parameter for the speed input as follows:

Input type = “0” (pulse) P.input = “0.000”

After modification, calibration has to be carried out. b) After pressing “power-ON”, the value of P.input will be checked.

If P.input is 0, then speed calibration will be carried out. c) The value for ttl.L and n can only be entered once.

Calibration procedure:

Press “Cal+1” key to enter the calibration mode, 2 seconds later, display show:

Input the total length of the belt ttl.L (input range: 0.001~ 499.999), press “C” key to clear and re-enter, or press “E” key to accept the input data.

Input the number of loop n (1~99), Press “C” key to clear and re-enter, or press “E” key to accept the input data.

Press “PRINT” key to calibrate, when the number of loop is completed, press “PRINT” key to stop after calibration, press “E” key to return to the normal weighing mode.

Input the value for length per pulse. Example: the total length of the belt is 0.5m, the number of pulse generated for

the belt to run for a complete loop is 50. This means that: P.inPut = (0.5 × 1000)/50 = 10.000mm Note: Set the length/pulse in mm.

Note: 1. Display the total value of Net/Gross weight after the final ticket printing.

2. When the power is turned on, accumulation starts from the time when the speed and weight cleared to zero are detected. In addition, the zero value is cleared just after ticket printing is done to start accumulation.

3. Accumulation total (only for format 1) When the power is turned on, the total value is read from the

EEPROM and accumulation starts from the time when the speed and weight are detected.

4. The same concept is applied to both belt weight and flow counter.
