BASIC WIRING
WARNING
The CX-1102 should only be installed by a qualified electrician.
Hazardous voltages may cause severe injury, death or equipment
damage.
The CX-1102 General Wiring Diagram illustrates the complete power and signal wiring for the CX-1102 control. Not
all of the connections will be required for your application. Refer to the CX-1102 Technical Reference Manual for
complete installation and wiring instructions.
The following instructions describe the basic wiring required for the unwind and wind modes of operation:
Power (J4 pins 1,2,3)
Position the power selector switch on the back of the CX-1102 to configure the power supply for 115 or 230 VAC. Wire
the power as shown in the diagram for 115 or 230 VAC.
WARNING
Applying 230 VAC power with the power selector switch in the
115 position will result in damage to the CX-1102 controller.
Run/Stop Logic (J6 pins 1,2,3,4,6)
In order to put the CX-1102 into “Run”, the F-Stop, Unload and H-Stop inputs must be shorted to common, usually
through a normally closed pushbutton. Short the Run input to common, usually through a normally open momentary
pushbutton. Thereafter, opening any of the Stop inputs will cause the CX-1102 to stop.
Unwind Jog Fwd/Rvs (J7 pins 1,2,3)
Unwind Jog Fwd/Rvs is a maintained input. When it is closed, it sends a Control Output signal to the drive at the
selected Jog Setpoint. As a maintained input, Unwind Jog Fwd/Rvs is only active when the operator device is closed.
Wind Jog Fwd/Rvs (J7 pins 4,5,3)
Wind Jog Fwd/Rvs is a maintained input. When it is closed, it sends a Control Output signal to the drive at the selected
Jog Setpoint. As a maintained input, Wind Jog Fwd/Rvs is only active when the operator device is closed.
Unwind Control Output (J3 pins 1,2)
The Unwind Control Output is a two wire connection between the CX-1102 and the Unwind motor drive. Insure that the
isolated common (J3 pin 2) is not used elsewhere.
Wind Control Output (J8 pins 1,2)
The Wind Control Output is a two wire connection between the CX-1102 and the Wind motor drive. Insure that the
isolated common (J8 pin 2) is not used elsewhere.
Unwind Enable and Wind Enable (J2 pins 1,2,3,10)
When these digital outputs are wired to the appropriate control input of the subject drive, it allows the CX-1102 to enable
and disable the drive as required. A low voltage pilot relay is usually required.
Frequency Inputs (J5 pins 1 thru 11)
The CX-1102 requires quadrature encoders for the unwind/wind frequency inputs. Refer to the CX-1102 Technical
Reference Manual for detailed diagrams illustrating the connections for the frequency sensors.
Setup (J6 pin 10,8)
The Setup input is a maintained input. It is used only during the system setup procedure to put the CX-1102 into “Setup
State”.
KeyLk (J6 pin 9,8)
The KeyLk input is a momentary input. It is used temporarily during the system setup procedure of the CX-1102.
