5. Operating Principle
The universal panel meter DAG-T4T00WSR is a quite versatile process indicator
with totalizing function. With a wide list of input types - thermocouples, thermo-
resistance, voltage and current the DAG-T4T00WSR is capable of measuring the
majority of the variables and sensors encountered in industrial processes.
Among others it contains two alarms (six functions), sensor offset, configuration
of parameters protected by password, USB communication, indication in degrees
Celsius (°C) or Fahrenheit (°F).

5.3 Alarms
The KOBOLD- digital universal panel meter DAG-T4T00WSR has two alarm
outputs:
ALARM1 - Relay SPST - Available on terminals 5 and 6.
ALARM2 - Relay SPST- Available on terminals 3 and 4.
The alarms can assume the functions described on Table 02:
Alarm off.

Alarm of the Absolute Minimum
Value. It triggers when the
value of the PV is below the
value defined by the alarm
Setpoint (SPA1 or SPA2).
SPA1
PV

Alarm of the Absolute
Maximum Value. It triggers
when the value of the PV is
above the value defined by the
alarm Setpoint.
SP


Alarm of the Differential Value. In this function the parameters “SPA1” and
“SPA2” represent errors (difference) between the PV and one reference value
(AlrF).

 Alarm of the Absolute Minimum Value. It triggers when the value of the totalizer
(TOT) is below the value defined by the alarm Setpoint.
 Alarm of the Absolute Maximum Value. It triggers when the value of the totalizer
(TOT) is above the value defined by the alarm Setpoint.


Alarm at overflow of totalizer.
 Alarms of Sensor Break (Sensor Break Alarm). It is activated when the Input
presents problems such as interrupted sensor, bad connection, etc.
Table 02: Alarm functions
Note: The figures are also valid for Alarm 2 (SPA2).
5.4 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.
5.5 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.

5.6 Totalizing function
This function allows continuous integration of instant PV values.
This continuous 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 every time
the indicator is powered up.
5.7 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”.
5.8 Totalizing/Integration scale factor (t.ScF)
Before being added to the total, the instant PV value is multiplied by the Scale
Factor.
5.9 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.
5.10 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.
 Key not used to any special function.
 Executes Batch Function - Addition
 Executes Batch Function - Subtraction
 Reset Total value
 Present maximum read value
 Present minimum read value
 Reset minimum and maximum values

DAG-T4T00WSR
page 10 DAG-T4 K05/0323
Two different functions can be assigned to F1 and F2 keys. The function to be
executed, Primary or Secondary, is determined by the amount of time the
function key is being pressed. If the function key is pressed for less than 1
second the Primary function is executed.
If the key is pressed for more than 3 seconds then the Secondary function is
executed.
The combination of the keys F1 and F2 pressed simultaneously can also execute
a Special Function. All Special Functions are available to the operator as follows:
F1_1: F1 Key, Primary Function.
F1_2: F1 Key, Secondary Function.
F2_1: F2 Key, Primary Function.
F2_2: F2 Key, Secondary Function.
F12_1: F1+F2 Keys, Primary Function.
F12_2: F1+F2 Keys, Secondary Function.
5.11 Totalizing function and alarms
The totalization alarm functions  and  allow the user to notify when a
total value is reached.
The alarm defined as Totalization Minimum Value Alarm ) is set when the
totalization value goes below the configured setpoint.
The alarm defined as Totalization Maximum Value Alarm () is set when the
totalization value goes above the configured setpoint.
As the totalization value can indicate up to 99999 99999 (or -9999 99999) the set
point values behave the same way. If the adjusted SP goes above 99999 (or
below -9999) the second SP part is displayed allowing the operator to see values
up to 99999 99999 (or -9999 99999).
The flags HIGH and LOW identify if the part being displayed is the SP most
significant part (HIGH) or the least significant part (LOW).
The totalization alarm (SP) is defined through the values SPA1 and SPA2. This
two parameters behave different from other parameters. The Back key allows the
operator to change the SP decimal digit to be set.
5.12 Overflow alarm
This alarm function is set when the totalized value surpasses 9999999999, which
is the maximum indication value.
