Elapsed Time

Type: Indicator Definition

The total accumulated time that Alarm 1 has been active on an Indicator since this parameter
was last reset. This does not include the time when the alarm condition has cleared. The
Elapsed Time is not affected by the Alarm 2 and Alarm 3 status.
Also refer to Alarm Operation, Exceed Time and Indicator.

Exceed Condition

Type: Limit Controller Definition

A state that occurs when the Process Variable exceeds the Limit Setpoint value. E.g. if the
PV is above the Limit SP when set for high limit action, or below the Limit SP for low limit
action. The Limit Controller will shut down the process when this condition occurs, and
cannot be reset until the Exceed Condition has passed.
Also refer to

and Limit Setpoint.

Input Filter Time Constant

Type: General Parameter

Annunciator, Exceed Time, Latching Relay, Limit Controller, Limit Hysteresis

Exceed Time

Type: Limit Controller Definition

The total accumulated time that a Limit Controller has been in the Exceed Condition since
this parameter was last reset.
Also refer to Elapsed Time, Exceed Condition and Limit Controller.

Indicator

Type: Indicator Definition

An instrument that can display a Process Variable. Alarm outputs are available that will
activate at preset PV values. Relay outputs can be selected to have a Latching function
similar to a Limit Controller output, but indicators do not have the necessary approvals for
safety critical applications. Other options are PV retransmission and Serial Communications.
Process control functions are not available.
Also refer to Alarm
Operation, Controller, Elapsed Time, Latching Relay, Limit Controller,
Multi-Point Scaling
, Process Variable, Retransmit Output, Serial Communications, Tare.

This parameter is used to filter out extraneous impulses on the process variable. The filtered
PV is used for all PV-dependent functions (display control, alarm etc). The time constant is
adjustable from 0.0 seconds (off) to 100.0 seconds in 0.5 second increments.
Display code =

"'/

, Default value = 2.0 seconds.

Also refer to Process Variable.

Input Range

Type: General Definition

This is the overall process variable input range and type as selected by the

%C)/

parameter

in Configuration Mode.
Also refer to Input Span.

Input Span

Type: General Definition

The measuring limits, as defined by the Scale Range Lower and Scale Range Upper Limits.
The trimmed span value is also used as the basis for calculations that relate to the span of
the instrument (E.g. controller proportional bands)
Also refer to Input Range, Scale Range Lower Limit and Scale Range Upper Limit.

Integral

Type: Controller Tuning Parameter

Refer to Automatic Reset.
