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.

 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.

DAG-T4T00WSR
DAG-T4 K05/0323 page 9
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.

DAG-T4T00WSR
DAG-T4 K05/0323 page 11
5.13 Minimum and maximum
The indicator is continuously storing the extreme input indication measurements,
or the minimum and maximum values. These values can be displayed at any time
by the operator by pressing the keys F1 and F2. Notice that the function Keys
should be set to  and .
To reset the maximum and minimum values and start another monitoring cycle,
just execute the function , which can be assigned to the keys F1 and F2.
When the indicator is powered off this information is not stored.
5.14 24 VDC auxiliary voltage source
The standard version of the DAG-T4T00WSR provides an auxiliary power supply
(24 VDC) for exciting field transmitters (terminal 13 on the rear panel).
6. Mechanical Connection
The indicator is meant for panel mounting. The sequence of steps is:
 Prepare a cut out of 93.0 by 45.5 mm on the panel
 Remove the mounting clamp from the indicator
 Insert the indicator into the cut out from the front side of the panel
 Place the clamp on the indicator again, pressing until firm grip to the panel

The terminals configurations are shown in Figure 01.
Figure 01: Input connections and power supply
Figure 02: Thermocouple, Pt100 and 50 mV signal connection
Figure 03: Current (mA) and Voltage (V) signal connection
This indicator offers an auxiliary 24 VDC +/-15% at 50 mA power supply which is
typically applied to power up two wire 4 to 20 mA field transmitters. The Figure
04 presents the wiring for this application.

7.1 Recommendations for the installation
 To minimize the pick-up of electrical noise, the low voltage DC connections and
the sensor input wiring should be routed away from high-current power
conductors. If this is impractical, use shielded cables. In general, keep cable
lengths to a minimum.
 The input signal conductors shall be positioned throughout the factory separate
from the output and the power supply conductors, in grounded conduits if
possible.
 The power supply of the electronic instruments shall come from a proper source
for the instrumentation network.
 It is recommended to use RC FILTERS (0,1uF in series with 100 ohms) to
suppress the noise generated by contactors coils, solenoids, etc.
8. Operation
The indicator front panel, together with its elements, can be seen on:
Indicators
Push buttons
Figure 02: Identification of the front panel parts.
Display: Shows the process variable (PV), the configuration parameter prompts
and their respective values/conditions.
Indicators A1 and A2: signalize the occurrence of an alarm condition.
Key P: Used to walk through the parameters in the menu cycles.
Increment key and Decrement key: Used to change parameter values.
Key : Go back to the previous displayed parameter. This key changes its
behavior starting to set the decimal digit to set.
9. Commissioning
When the controller is powered up, its firmware version is displayed for 3
seconds, after which the DAG-T4T00WSR starts normal operation, when the
value of PV is displayed and the outputs are enabled.
Before the indicator is ready to be used in a given process, it requires some basic
configuration, consisting of assigning values to the parameters according to the
desired behavior. The user shall understand the importance of each parameter
and determine a valid condition or a valid value for each one of them.

DAG-T4T00WSR
page 14 DAG-T4 K05/0323
The configuration parameters are grouped in levels according to their affinity. The
5 parameter levels are:
1 – Operation
2 – Alarms
3 – Input
4 – Totalizer
5 – Calibration
The “P” key provides the access to the levels and to the parameters of these
levels.
Keeping the P key pressed, at every 2 seconds, the indicator jumps from one
level to another, presenting the first parameter of each level:
Measurement PV>>>>>>>>>>PV …
To enter a particular level, simply release the P key when the first parameter in
that level is displayed.
To walk through the parameters in a level, press the P key with short strokes. To
go back to the previous parameters, use the Key.
The display alternates the presentation of the parameter prompt and its value.
The parameter value is displayed with a light blinking to differentiate it from the
parameter prompt.
Depending on the level of parameter protection adopted, the parameter 
precedes the first parameter in the level where the protection is active. See
section Protection configuration.

The Master Password is intended for allowing the user to define a new password
in the event of it being forgotten. The Master Password doesn’t grant access to all
parameters, only to the Password Change parameter (). After defining
the new password, the protected parameters may be accessed (and modified)
using this new password.
The master password is made up by the last three digits of the serial number of
the controller added to the number 9000.
As an example, for the equipment with serial number 07154321, the master
password is 9 3 2 1.
The indicator serial number can be obtained by pressing for 5 seconds.
