4.4 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.

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.

 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

Operating manual

- 7 -

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 then 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.

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.

4.11 Overflow alarm

This alarm function is set when the totalized value surpasses 9999999999, which is the maximum

indication value.

4.12 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 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.

4.13 24 VDC auxiliary voltage source

The standard version of the DA9602 provides an auxiliary power supply (24 VDC) for exciting field

transmitters (terminal 13 on the rear panel).

4.14 Interface

USB-Port (virtual COM-Port) to program the digital display.

5. Installation

5.1 Mechanical installation

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

5.2 Electrical installation

The terminals configuration 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.

Figure 04: Auxiliary 24 VDC usage example

5.3 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.

6. 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.

7. Start up

When the controller is powered up, its firmware version is displayed for 3 seconds, after which the

DA9602 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.

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 Pkey 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 Pkey 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.
