1.0 - Introduction
1.1 - Description
The DMY-2030-CC Indicator monitors one input of mVdc signal,within the range
from -30 mV to +30 mV, provided by a load cell.A 10Vdc voltage source,isolated from
the output and with short-circuit protection,is provided to power the load cell.
It can communicate with computers by means of an optional communication
module RS-232 or RS-422/485.
All configuration data is protected by password and is stored in a non-volatile
memory.
According to its modularity design concept, the Indicator accepts up to three
output modules. One can make use of one retransmitter output (4-20mA, 1-5V, 0-10V) or
one SPST alarm module and up to two SPDT alarm modules (also solid state relay or
open collector voltage). The alarm outputs can be configured independently to operate
with latch, what requires the acknowledgement of the operator, by means of the front
panel Keys, in order to deactivate the outputs after the process variable returns to normal
condition. The outputs are electrically isolated from inputs.
Fig. 1 - DMY-2030-CC Indicator front panel
The front panel has a high visibility display configurable up to 4 ½ digits to show
the process variable. The leds are used as a visual indication of alarms. During
configuration, the display shows mnemonics and parameter values.
It accepts 75 to 264Vac or 100 to 360Vdc (with any polarity) power supply.
The instrument has extruded aluminum case which avoids electrical noise,
electromagnetic interference, radiofrequency interference, etc., and its robust
construction makes it tough enough for the most hostile environment.

2.3 - Input Signal Connection
The Indicator input can receive amV signal applied to terminals 2(+) and 3(-).
The input is enabled by software configuration (see section 3.2 on
Configuration).
In order to avoid noise in the wiring, use twisted pair cable and cross sensor
connection wire inside a metallic tube or use shielded cable. Make sure to connect only
one shield wire end either to board terminal or to sensor ground, as shown in the next
items.

3.0 - Operation
3.1 - Normal operation
The DMY-2030-CC Indicator has two modes of operation: normal operation and
configuration mode.
During normal operation, the Indicator monitors the inputs, verifies alarm
conditions and activates the outputs when necessary.
Configuration mode is used to select and configure all the Indicator parameters.
The normal operation mode, in which the Indicator is to be found most of the time,
is called level zero. In this level, the three front panel keys have the following functions:
Key Function
ENTER
Changes information shown on the display.
When the display shows the process
variable (PV), it goes to the maximum peak
value (MAX),if enabled.Next,it goes to
the minimum peak value (MIN), to the
setpoints of alarms 1 to 3 (SP1, SP2 and
SP3), if enabled,to the CONF mnemonic
(which allows one to enter the configuration
level)and to the process variable again.
Allows the acknowledgment of alarms
configured with latch function, after the
alarm condition returned to normal state.
UP
When CONF is shown, the display changes
to PASS and it requires the password for
changing from level zero to level one.
Gives access to the maximum and
minimum peak values or allows the reset of
these values.
When the process variable is shown, it
presents the mnemonics of the alarms
which require acknowledgment.
Increases the setpoint value of the alarm
shown.
DOWN
Resets the indication and the values of
maximum and minimum peaks and the
registered peak values.

The information sequence presented on the display is shown in figures 6 and 7
according to the configuration of the maximum and minimum peak register option
(REG option in the GENERAL configuration level):
Fig. 6- Information in the operation level when the peak register option is enabled.
Fig. 7- Information in the operation level when the peak register option is disabled.
The values of the maximum and minimum peaks of the process variable detected
in the input can be seen in the operation level:the MAX and MIN mnemonicsindicate the
maximum and minimum values, respectively.
The instrument allows the storage of five maximum and five minimum peak values
in its memory.
When the process variable indication is shown,the DOWN key can be used to
reset the value indicated (TARE function). Such adjustement is stored in the indicator
memory.
The value of the peak exhibited by MAX or MIN can be reset by pressing the UP
key,in case the REG option is disabled.When the process variable is shown and REG is
enabled,one must press DOWN to reset the maximum and minimum peak values and
apply the TARE function.
In order the see the registered maximum (minimum) peak values, when the REG
option is enabled,one must press the UP key when the value associated to MAX (MIN)

is shown. In this way,one accesses a menu with five registers indicated by the
mnemonics MAX.1 to MAX.5 for the maximum peaks (MIN.1 to MIN.5 for the minimum
peaks).The first register of the menu, MAX.1 (MIN.1), refers to the most recently stored
value.When pressing the DOWN key for the maximum peak,the value of each register
is displaced to the next one,that is,MAX.1 receives the new value,while the previous
value of MAX.1 goes to MAX.2, the previous value of MAX.2 goes to MAX.3, and so on.
For the minimum peak,a similar process follows.
The registered values for both the maximum and the minimum peaks are reset
when the DOWN key is pressed during the exhibition of the process variable (the same
key used to apply the TARE function).
The normal operation and configuration modes present a “timer” which make the
display return to the process variable if it shows any other kind of information and no key
is pressed for 1 minute. It does not apply to the Calibration level (Calib. mnemonic). See
item 3.2 on Configuration.
3.2 - Configuration
In order to access the configuration mode the operator is required to provide a
password which avoids a non-authorized person to change any critical parameters of the
process. When UP is pressed, while CONF is shown in the normal operation mode, the
PASS warning is displayed and the user should press the UP, DOWN and ENTER keys
(exactly in this order) to access the configuration levels. If the user provides an incorrect
sequence of keys or if it takes more than 15 seconds for the password to be given, the
display returns immediately to the normal operation level. This procedure is shown in
figure 8.
Note: In the diagrams below, the rectangles represent
the display appearance after pressing the keys.

DEC.PT - sets the decimal point position for the visualization of Engineering units
in the display. There are up to four decimal places.
OFSET (as is shown in the display) - allows the user to enter an off-set value in
Engineering Units to be added to the measured variable.
FILTER - this parameter provides the time constant of a first order digital filter
associated to the selected input (range from 0.0 to 25.0 s). In order to disable the filter, set
the parameter to zero.
Levels 2,3 and 4 - Alarms
The Indicator accepts up to three alarm modules: relays 1, 2 and 3. The alarm
conditions of alarms 2 and 3 can also be visualized by the couple of leds on the front
panel, LED 1 and LED 2, respectively.
The ALAR.1 mnemonic corresponds to the configuration of relay 1(output 1),
ALAR.2 to relay 2(output 2), and ALAR.3 to relay 3(output 3). The connectors on the
Power Supply Board corresponding to each one of the relays are listed below:
Relay

Refer to section 4.3 on the Installation of Optional Modules for further details.
Each module can be configured as a high alarm (HI mnemonic), low alarm (LO),
or deviation alarm of the process variable from the setpoint (DEV), or be disabled (NO
mnemonic).
When configuring the high or low alarm it is necessary to set its setpoint SP and
hysteresis HYST. The deviation alarm requires the configuration of the setpoint SP, the
deviation parameter DV to determine the values above and below the setpoint where the
alarm is activated (SP-DESV and SP+DESV), and the hysteresis HYST (in U.E., from 0
to 30000) to define the band (between SP-DESV+HIST and SP+DESV-HIST) of return to
the normal or non-alarm condition. One can also use the LATCH and DELAY functions
for each alarm.
