Blocking initial of the alarm
The initial blocking
option inhibits the alarm from being recognized if an alarm condition is present
in the process when the indicator is first energized. The alarm will be enabled only after the
occurrence of no alarm condition.
The initial blocking is useful, for example, when one of the alarms is set up as a minimum value
alarm, which may cause the activation of the alarm soon upon the process start-up; an occurrence
that maybe undesirable in many cases.
The initial blocking feature is not valid for the functions
t.lo
,
t.Hi
,
t.ofl
and
ierr
.
4.5
Auto range function (
AVTO.R
)
The indication limits can be set by using operator’s knowledge about the process. By knowing the
relation between the current process variable value and the desired indication in two points the
indication limits can be easily set.
The known PV values are set through
P1.Set
and
P2.Set
parameters which are presented when
the Auto Range function is enabled:
avto.r
=
yes
.
If the function Auto Range is used the parameters
inLL
and
inHL
are automatically defined.
This function is only available for analog linear input signals.
4.6 Totalizing
function
This function allows continuous integration of instant PV values.
This continunous integration is stored in a non volatile internal memory and can also be presented
at the indicator display by choosing TOTAL screen which is identified by the symbol TOT. This
symbol is always presented when the TOTAL is being presented.
The TOTAL value is presented with up to 9 digits (999999999) but when this value is bigger than
99999 it is splitted in two separate screens indicating the most and least significant parts and
identified with the symbols TOT HIGH and TOT LOW on the display.
The TOTAL value can be erased through the keyboard or can be reset everytime the indicator is
powered up.
4.7
Totalizing/Integration time base (
t.base
)
The instant PV value integration is executed at a fixed time interval which is defined by a
configuration parameter.
The Time Base options are “second”, “minute”, “hour” and “day”.
4.8
Totalizing/Integration scale factor (
t.ScF
)
Before being added to the total, the instant PV value is multiplied by the Scale Factor.
4.9
Batch totalizing function
This function allows the operator to execute the totalization only when a pre configured function key
is pressed.
This function allows the user to add or subtract the instant PV value to/from the total accumulated
value.
4.10 F1 and F2 function keys
The F1- and F2-Keys can execute several different functions which should be set by the user when
configurating the indicator.
