NC-62CV SERIES CONTROLLER FOR SPEED GAUGING AND COUNTING        Adopting the advanced SCM and large-scale IC technologies, NC-62CV Controller for Speed Gauging & Counting is designed for the purpose of industrial on-spot counting control and linear speed (or rotary speed) gauging. It can work continuously on-line.

1. Features
·Concise man-machine interactive style, convenient keyboard operation and data input;
·Two relay outputs for counting and alarm;
·Can gauge linear or rotary speed, count output quantity of products per unit time;
·6-digit numerical display, 6 touch-style buttons, 4 LED indicators;
·Applicable parameters can be protected when power off and stored in memory for over 100 years;
·Pressing the "V/C" button on the control panel can decide to display counting or linear/rotary speed without effecting the current operation status of counting and controlling;
·Programmable independent invarient for counting, and invarient for linear/rotary speed counting.
·Range of setting: 0.001 to 999.999;
·Small and compact structure;

2. Functions

2.1 Counting control
    Two alarm values fo counting can be preset through keyboard. The Controller counts the pulse sent by the sensor and multiplies it by the counting invariant (3-digit integer, 3-digit decimal). The result is displayed on the panel. When the amount counted reaches the preset value "OUT1" for alarm, Relay I is energized and the LED for "OUT1" on the panel lights up. Meanwhile the Controller continues its counting. When the amount counted reaches the preset value "OUT2" for alarm, Relay II is energized and Relay I is deenergized. The LED for "OUT2" lights up while the LED for "OUT1" goes off. Relay II will not be deenergized until it is energized for a preset period of time (1 - 20s). When Relay II starts being energized, the display is cleared to zero and the Controller starts another new counting. Thus, the whole process of operation keeps on repeating itself.

2.2 Speed gauging
    When the Controller is adjusted to speed-gauging function, it gauges the frequency value of the sensor-sent pulse and multiplies it by the preset invariant. The result is displayed on the panel. With different invariants (3-digit integer, 3-digit decimal) preset, the changing speed is displayed directly on the panel (4-digit integer, 2-digit decimal), such as linear speed (m/s) or rotary speed (rpm). Counting of sensor-sent pulse and other controlling will not be interfered by the displaying of linear speed or rotary speed.
