Limit Tests
8-3
The 2-stage limit testing process is shown in
. If limit 1 fails, the L1 message is
displayed and the test is finished. Limit 2 is not tested because the pass band relationship
between the two stages implies that if limit 1 fails, limit 2 must also fail. If limit 1 passes,
the limit 2 test is performed. If limit 2 fails, the L2 message is displayed. If both limit 1
and limit 2 pass, the OK message is displayed. The display messages for limit tests are
summarized in
.
A test is only performed if it is enabled. Therefore, you can perform a single-stage test or a
2-stage test. In the flowchart (
), operation simply proceeds through a disabled
test.
