Further Steps and Checks
• The AVM may be disconnected; check the wiring.
• Perform a System Reset to clear the fault and cause another test to occur.
2.1
Concurrency
Fault
Cycle Input
On a dual-channel input with both inputs in the Run state, one input went to the Stop
state then back to Run.
• Check wiring.
• Check input signals.
• Consider adjusting debounce times.
2.2
Simultaneity
Fault
Cycle Input
On a dual-channel input, one input went into the Run state but the other input did not
follow within 3 seconds.
• Check wiring.
• Check input signal timing.
2.3 or 2.5
Concurrency
Fault
Cycle Input
On a complementary pair with both inputs in the Run state, one of the inputs changed
to Stop then back to Run.
• Check wiring.
• Check input signals.
• Check power supply providing input signals.
• Consider adjusting debounce times.
2.4 or 2.6
Simultaneity
Fault
Cycle Input
On a complementary pair, one input went into the Run state but the other input did not
follow within the time limit.
• Check wiring.
• Check input signal timing.
