Testing Methods and Tools
Programmable contacts can be changed to “a” or “b” contacts with a solder
jumper. Refer to Output Contact Jumpers on page 2.8 in Section 2:
Installation for jumper locations. Using contact operation as an indicator, you
can measure element operating characteristics, stop timers, etc.
Tests in this section assume an “a” output contact.
Sequential Events Recorder (SER)
To test using this method, set the SERn to trigger for the element under test.
With the SET R command, put the element name in the SER1, SER2, or
SER3 setting.
Whenever an element asserts or deasserts, a time stamp is recorded. View the
SER report with the SER command. Clear the SER report with the SER C
command.
