CUB2LU/Q Data Sheet/Manual - Red Lion Controls

APPLICATION FLEXIBILITY VIA RECONNECT OPTIONSSelection of desired operating modes is easily done by moving terminal leadsin the Input Connector Body. The connector body is polarized to preventincorrect insertion, and locked in place by the connector latch to avoidaccidental disengagement. Connectors are supplied with the 4 leads installed asshown at right. A spare blue lead is supplied in the hardware pack.Removing Terminal: Insert blade of a small screwdriver into slot of connectorbody, and gently push in to disengage the locking pawl. Pull terminal out.Inserting Terminal: When inserting into connector body, make sure thelocking pawl is toward the slot in the body. Push terminal in until the lockingpawl snaps into slot.TYPICAL APPLICATIONSUP/DOWN COUNTING - CUB2LUUp/Down counting can be accomplished by using a count sourceand a direction signal. The count signal is applied to the Count Inputand the direction is applied to the Down/Up Input. The counter willincrement on the falling edge of the Count Input when the Down/UpInput is held low. The counter will decrement on the falling edge of theCount Input when the Down/Up Input is held high. If the Down/UpInput is left open, the counter will decrement because it is pulled highthrough an internal pull-up resistor.QUADRATURE COUNTING - CUB2LQWhen applying a quadrature signal to a CUB2LQ, asin positioning applications, the counter will incrementwith every falling edge of the Count Input if the QuadInput is low. The counter will decrement with everyrising edge of the Count Input if the Quad Input is low.When the Quad Input is high, no change in count valuewill occur.ELECTRICAL CONNECTIONSWiring runs to count sensors or remote reset contacts can be made withalmost any kind of wire and over distances of hundreds of feet, due to theadvantages of low-voltage, low-current operation. The inherent noise immunitybuilt into the CUB2LU and CUB2LQ, permits use of unshielded wiring in someapplications, however the following precautions are advisable.1. Avoid long wire runs in cable troughs or conduits with power circuits.2. Mount the CUB2LU or CUB2LQ counter in a panel that is grounded to themachine frame.Shielded wire is recommended in high electrical noise environments.ORDERING INFORMATIONMODEL NO.
