Danger
Second level alarm that occurs when the transducer signal level exceeds the
selected Danger/Alarm 2 setpoint. This setpoint can be set on the Setpoint
screen.
100 ms option
The 100 ms (typical) option applies to the Danger time delay only and has the
following results:
If the 100 ms option is off (
):
- The Danger time delay can be set at one second intervals (from 1 to 60).
- The Danger time delay can be set for all available proportional values.
If the 100 ms option is on (
):
- The Danger time delay is set to 100 ms.
- The Danger time delay can only be set for the primary proportional value.
Zero Position (Direct)
Represents the transducer DC voltage corresponding to the zero indication on
the channel's meter scale for the direct proportional value. The amount of
adjustment allowed is dependent upon the Direct Full Scale Range and the
transducer OK limits. For maximum amount of zero adjustment, gap the
transducer as close as possible to the ideal zero position voltage based on the
full-scale range, the transducer scale factor, and the Upscale Direction. For a
mid-scale zero the ideal gap is the center of the range.
Adjust Button
Adjust the Zero Position voltage. When this button is clicked a utility starts that
helps you set the direct zero position voltage. Since this utility provides active
feedback from the 3500 rack, a connection with the rack is required. Refer to
Section 5.2 (Adjusting the Scale Factor and the Zero Position).
