Pulse Width The length of signal transmission in ms sent to the
circuit breaker that determines the length of time
that the Trigger Output remains in the active
condition.
Trigger Delay The length of time between the inception of the test
and when the trigger is set.
This defines the timing relationship between the
trigger input and the trigger output. The Trigger
Out channel can be used in conjunction with
internal triggering, when controlling the test
initiation with the Trip/Close control, or with an
external System trigger input. Trigger Out cannot
be used with Event Triggers, like Aux. Contact
Trigger input.
When used with:
• Internal triggering (Trip/Close control), the
delay can be either positive or negative.
• A positive delay causes the Trigger Out
channel to transition to the active state after
the test/recording has begun (delayed by
Trigger Delay value).
• A negative delay causes the Trigger Out
channel to transition to the active state
immediately after the safety switch is
activated, with the Trip/Close commands
and recording delayed by the Trigger Delay
value.
• External triggering, only positive delay values
are valid. The Trigger Out channel transitions
to the active state after the external trigger in
event occurs, which is delayed by the Trigger
Delay value.
Polarity Active Closed state only.
