INSTRUMENT ID PARAMETER
The Instrument ID parameter is used to provide specific identification for a Tension Controller. This is extremely important when using several Tension Controllers in a process. The Operator ID is the ID of the user who is going to operate the Tension Controller or service the instrument. Select three letters or numbers or any combination of the two that adequately identifies the user. We have provided some examples below for your assistance. The Operator ID is used in connection with the security level of the user.
UNIT OF MEASURE PARAMETER
The Unit of Measure Parameter sets the scale to either English or Metric units.
The Selections are:
Pounds Force (lb)
Newtons (N)
Pounds per Linear Inch (PLI)
DECIMAL POINT PARAMETER
The Decimal Point Parameter is set to determine the resolution you want for tension control. Here you set the location of the decimal point for the tension resolution. The higher the number the farther to the left the decimal point moves and the higher the resolution of the scale.
AVERAGES PARAMETER
This setting is to aid in ignoring the effects of disturbance. If there is a lot of zone disturbance, tension fluctuations can be seen. Applications requiring very quick tension readings should reduce this setting to its minimum. If the tension is unstable due to zone instability, increase the averages. This sets the number of readings that will be used to compute the Tension. The average is a sliding average so that a new average is available for display at every reading. The Tension Controller does 55 updates per second, which translates to an update approximately every 20 milliseconds. If you average enough tension readings the loss or gain remains smooth. If you average the tension too much you can cause an overreaction.
WAVERSAVER® PARAMETER
Typically, mechanical noise (from other machinery in a plant environment) is present in forces larger than the weight forces trying to be detected. The Tension Controller is fitted with WAVERSAVER® technology that eliminates the effects of vibratory forces present in all industrial tension control and measurement applications. By eliminating the factor of vibratory forces the Tension Controller is capable of identifying the actual tension data. WAVERSAVER® enables the Tension Controller to distinguish between actual tension data and mechanical noise, both of which are typically transferred to the Tension Controller by the load cell signal. WAVERSAVER® can be configured to ignore noise with frequencies as low as 0.25 Hz. One of four higher additional cut off frequencies may be selected to provide a faster instrument response time. The WAVERSAVER function is user selectable and can be turned off.
MAXTENSION PARAMETER
The Maxtension value should be any value between the tare weight and maximum capacity of your combined load cells that will not cause faults in your process or the largest value of tension you expect to see. The HI 3300 tares or zeroes the instrument when you set the reference weight in Traditional Calibration or C2 Calibration. (See Chapter 5, Traditional Calibration Procedures, C2 Calibration Procedures.) The PID input is scaled by this value. Also when you press the plus or minus buttons up or down to increase or decrease the setpoint, each time you push the button it increases or decreases the setpoint by 1% of the Maxtension.
SENSOR TYPE PARAMETER
The Sensor Type parameter enables you to select four load sensor sensitivity
