1.10
Output Fault
Sequence timing error:
•
Perform a System Reset to clear the fault
2.1
Concurrency Fault
On a dual-channel input, or a complementary input, with both inputs in the Run state, one input
went to the Stop state then back to Run.
On a dual-complementary input, with both pairs of inputs in the Run state, one pair of inputs
went to the Stop state then back to Run.
•
Check the wiring
•
Check the input signals
•
Consider adjusting the debounce times
•
Cycle input
2.2
Simultaneity Fault
On a dual-channel input, or a complementary input, one input went into the Run state but the
other input did not follow the change within 3 seconds.
On a dual-complementary input, one pair of inputs went into the Run state but the other pair of
inputs did not follow the change within 3 seconds.
•
Check the wiring
•
Check the input signal timing
•
Cycle input
2.3 or 2.5
Concurrency Fault
On a dual-complementary input, with both inputs of one complementary pair in the Run state,
one input of this complementary pair changed to Stop then back to Run.:
•
Check the wiring
•
Check the input signals
•
Check the power supply providing input signals
•
Consider adjusting the debounce times
•
Cycle input
2.4 or 2.6
Simultaneity Fault
On a dual-complementary input, one input of a complementary pair went into the Run state, but
the other input of the same complementary pair did not follow the change within the time limit:
•
Check the wiring
•
Check the input signal timing
•
Cycle input
