1.2 System Environment Recommendations/Requirements
1.3 Getting Started
Installing the CPT-1 for the first time it is recommended that you follow these steps:
1) Verify that you received all of the components that you ordered. Note: cables and breakout board for the
controller are options that can be selected at the time of purchase.
2) Check that you have a compatible power supply to power the controller. See Section 4.1
3) Check that you have a compatible communication cable for setting up the controller. See Sections 4.2 and 4.3
4) Download the setup software from www.wkfluidhandling.com/cpt-1.
5) Verify that your computer is able to connect to the controller.
a) Power up the controller with correct power source
b) Connect the communication cable correctly. (Ethernet cables should go from the controller to a network
switch, not your PC)
c) Install and launch the Smart Control Software.
d) The connections dialog should appear at launch. Verify that your controller appears on the list and click
the connect button. See Section 7
e) Once connectivity is verified disconnect from the software, and disconnect power and communication
cable.
6) Install CPT-1 in the desired location.
7) Connect 44-pin connector and use the wiring guide in Section 5 to connect system.
8) Connect to controller (same as before) and configure the CPT-1 settings to match your system needs.

2.1 CPT-1 Cycle Rate Translator
The CPT-1 control box is a small I/O communication device that converts the pump’s cycle rate to the cycle rate
that works with the tool’s algorithm. The control box has:
• 44-pin HD D-Sub Connector: Sends and receives digital signals.
• Indicator Lights: Show when each digital signal is active.
• Power Port: Takes 18-36 VDC input to power the controller.
• Ethernet Connector: This is used by the setup software to configure the controller.
• RS 232 serial communication: This is an alternate method of connecting to configure the controller.
Figure 1 shows an image of the WK CPT-1 controller with the above features labeled.

The CPT-1 has been designed to be an interface between the tool’s algorithm and a pneumatic pump. This interface
is needed when inserting an alternate pump into an existing tool; frequently the alternate pump will have a different
cycle rate than the previous pump which may cause the tool to alarm out.
The CPT-1 is able to operate the pneumatic pump at the cycle rate that is optimal for the pump. Then, the CPT-1
will scale the pump’s cycle rate by a factor set by the user and send the scaled cycle rate back to the tool. The CPT1 can be configured to work with any system setup.

4.1 Powering the CPT-1
There are two methods of powering the CPT-1: 18-36 VDC power connector and Power over Ethernet (PoE).
By default the CPT-1 is setup to use the external power adapter. Simply connect an appropriate DC power to the
connector as shown in Figure 3.
To setup PoE, find the jumpers labeled EXT and PoE on the bottom face of the controller. See figure 4. Move the
jumpers from EXT to PoE locations. POE can now be used.
