5.7 Manufacturing tests
The procedures for testing certain key functionalities of the
Sentinel LCT8 are described in this section. The Sentinel
LCT8 Watchdog test, keypad test, display test and IO test are
available to the user. As an example, the IO test is discussed
in detail in this chapter. All other manufacturing tests are
performed in a similar manner.
The IO test is used to troubleshoot any problems associated
with damaged electronics or changes in the process
conditions that may be affecting the Sentinel LCT8 inputs
and/or outputs. Proceed to the following three sections for
instructions on how to test specific IO functions.
