Installation and Setup
Each user-control application may be different, it is left to the reader to design and create the
customer-end portion of a User I/O interface. Use the signal information provided on the pre-
vious page. An example of one possible application is shown in the following diagram.
Example of Customer-Provided Application using the User I/O
• Start switch can be tied to pins 1 and 9 as shown. this will provide 5 volts in case the
customer does not have a supply to operate user I/O signals.
• Pins 2 and 6 must be tied together for proper Start signal operation.
Note: These must NOT be tied to earth ground. Noise due to ground loops could
be injected onto the signals. This will cause improper operation, but will not
damage the unit.
• Pins 3 and 4 must be tied to pin 6 for operation of the Temperature Limit and Test Run-
ning LED’s respectively, as shown.
• Power, Amplitude and Temperature must be referenced to pin 14 for proper signal
measurement.
