English term or phrase: mismatch
sensors, safety applications, muting module

The input channels (A & B) must meet the Simultaneity Requirement. A mismatch of more than 3 seconds results in a lockout. A lockout that is due to a failure to meet the Simultaneity Requirement (see page 52) can only be cleared by cycling the MSSI (or the USSI, depending on which failed) with simultaneity being met, and when the Module is configured for Manual Reset, then performing a reset routine.

mismatch = difference?

Explanation:
Here, 'mismatch' is being used to refer to a difference in the arrival time of the two signals at the defined point in the circuit.
Indeed, a timing 'error'; the arrival times of the two signals are 'not matched'

In response to mk_lab\'s peer response to my comment.

Sorry, I\'m afraid I can\'t even understand your response! I don\'t follow the distinction you seem to be trying to make between \'mismatch duration\' and \'value of mismatch\'? In any event, the context given makes it pretty clear to me that 3 s IS indeed the duration: \"...a mismatch of more than 3 seconds...\" What else could it mean?
I\'m sure all this means is that the two signals A and B (whatever those may be) must arrive within 3 seconds of each other, or else an error is generated. I believe it\'s as simple as that, and we don\'t need to go looking any further into more complex questions of clocking, data skew, etc....

error


Explanation:
A term used in RF systems to describe the situation when two devices having different impedances are connected to each other. Mismatches cause excess signal losses and other problems.

mismatch here is equal to \"delay\" of clock signals in one of input channels (A or B)

As responce to Dusty\'s comment: \"I\'m sure all this means is that the two signals A and B (whatever those may be) must arrive within 3 seconds of each other, or else an error is generated.

It\'s difficult to be sure wothout detailed description of the circuit, but I guess that signal mismatch in channels A & B is probably much shorter than 3s (which is too long delay value), saying some microseconds or so. But when duration of this mismatch exceed 3s, system would be lockouted.

disagree  Tony M: There's nothing in the given context to suggest this is a clocked system, and indeed, a large mismatch of 3s would tend to render this unlikely. * * * Please see further comment above ^ ^ ^

  -> I think, it's obvious, that 3s time is a mismatch duration, but not the value of the mismatch itself. ||| Please, see my added comment above.
