pr
es
ys
PRESYS DMY-2011, 2035 and 2036 Indicators are microprocessor-based
instruments that show all kind of industrial process variable, such as: temperature,
pressure, flow and level. They have non-volatile internal memory (E2PROM) to store
calibration values. Their high accuracy is warranted by autocalibration techniques
based on high thermal stability voltage reference.
They can communicate with computers by optional communication module
RS-232 or RS-422/485.
The Indicators are able to monitor two universal standard inputs and accept
direct connection of thermocouples, RTD, current (mAdc) and voltage (mVdc, Vdc).
Thermocouples and RTD inputs are linearized automatically by tables stored in
EPROM memory. A 24Vdc voltage source isolated from output and with short-circuit
protection is provided for transmitter power supply.
The type of input selected by the user is enabled by jumpers and by the
software configuration. All configuration data can be protected by a password system
and are stored in the non-volatile memory in case of power failure.
According to modularity design concept, the instruments accept up to four
output modules. The type of outputs are: retransmittion, SPDT relay, SPST relay and
solid state relay. The outputs are isolated from the inputs.
They accept 90 to 240VAC or 130 to 340VDC (with any polarity) power supply.
The equipments have extruded aluminum case which avoids electrical noise,
electromagnetic interference, radiofrequency interference, etc. and their robust
construction makes them tough enough for the most hostile environments.

Figure 2 - DMY-2035 and DMY-2036 Indicators front panels
On the front panel of the instruments there are two displays configurable up to
four high visibility digits which show the process variables of channel 1 (upper
display) and channel 2 (lower display). During configuration, the display shows
mnemonics and parameter values. The leds and the display can be used as a visual
indication of alarm or they can be associated with the alarm outputs. So, there are up
to seven alarm indications available (four alarm modules together with the display
and leds). The alarm outputs can be configured, independently, to operate with latch,
demanding the operator acknowledgement by means of the front panel keys in order
to deactivate them after the process variable returns to normal condition.
Up to two rettransmitter outputs are available to provide a linear output signal
from 4 to 20 mA, 1 to 5V or 0 to 10V proportional to the input process variable being
measured. This signal allows the retransmissions of the variables to a distant
location. When using only one analog output, up to three alarm modules can be
used, and when using two analog outputs, up to two alarm modules can be used.

2.2 - Electrical Installation
DMY - 2011, 2035 and 2036 Indicators may be powered by voltage between
90 and 240VAC or 130 to 340VDC, any polarity. Remember that the internal circuit is
powered whenever the instrument is connected to the mains.
Input and output signals must be connected to the instrument only when it is
turned off.
Figure 5 shows the instrument rear terminals for connection to power supply,
ground, communication, process input and output signals.
Signal wiring must be kept far away from power wires.
Due to its metal case the instrument ground should be connected to earth
ground. Never connect the ground to neutral terminal.

The connection of a certain type of sensor in input 1 does not restrict the use
of other sensor in input 2.
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.
WARNING: GROUNDING TWO SHIELD WIRE ENDS MAY CAUSE NOISE IN THE
INDICATOR.
ys
2.3.1 - Thermocouple Input
pr
es
When using only one thermocouple, connect it to input 1, in order to get a
better precision in the temperature measurement, since the cold junction sensor is
placed near input 1.
In order to reduce the error due to cold junction compensation, use thermal
paste in the rear, at the terminals where the thermocouple is connected to the cold
junction sensor.
Connect the thermocouple to terminals 2 (+) and 3 (-) to use input 1 or to
terminals 5 (+) and 6 (-) to use input 2 as shown in figure 6.
Use appropriate compensating cables with the same material of the
thermocouple in order to connect it to the instrument. Check if the thermocouple
polarity is equal to those of the terminals.

2.3.2 - RTD Input
ys
An RTD input device may be a 2-wire, 3-wire or 4-wire RTD. All types of
connection are shown in figure 7.
A 2-wire RTD is connected to terminals 1 and 3 when using input 1 and to
terminals 4 and 6 when using input 2 as shown in figure 7.
A 3-wire RTD is connected in the same way as explained for a 2-wire RTD,
adding the connection of the compensation wire to terminal 2 for input 1 and to
terminal 5 for input 2 as shown in figure 7.
Connect a 4-wire RTD as indicated for a 3-wire RTD and keep its forth wire
disconnected. See figure 7.
With a 3-wire RTD one gets a better precision than with a 2-wire RTD.
Use wires of same material, gauge and length on all 3 terminals of each
channel for compensating resistance. The maximum resistance of each connection
wire must be 10 Ω. Use 18 AWG wire (minimum) for distances up to 50 m and 16
AWG for distances greater than 50 m.

DMY-2011, 2035 and 2036 Indicators have two modes of operation: normal
operation and configuration mode.
During normal operation, the Indicators monitor the two inputs and show the
totalizations, verify alarm conditions and activate the four outputs if necessary.
Configuration mode is used to select and configure all the Indicator
parameters.
The normal operation mode, in which the Indicators are to be found most of
the time, is called level zero. In this level, the three front panel keys have the
following functions:
(*) In order to view the monitored variable, continue to press the ACK key. In
case there are no activated relays, the No.Ac. message will be shown.
3.2 - Configuration
In order to access configuration mode the operator is required to provide a
password which avoids a non-authorized person to change any critical parameters of
the process.
So, when ENTER is pressed within the normal operation mode, one of the
following events can happen, depending on the current configuration:
i) To access directly level 1 (GENERAL) of configuration mode, which indicates the
instrument was not configured with a password system.
ii) To display the PASS warning, indicating that the instrument is provided with a
password system (a key sequence or a value), according to figure 11.

In case of a key sequence password, the user should press the UP, DOWN
and ENTER keys (exactly in this order) to access the configuration levels.
For a value password, the user must press the ENTER key for a second time
in order to view the number 00000 with the right end digit blinking. The position which
is blinking indicates the digit in the number to be changed by the user with the UP
and DOWN keys. Move to the digits on the left by pressing ENTER. After entering all
digits, press ENTER again. If the password is correct level 1 is accessed; otherwise,
it returns to normal operation (see figure 11).
The user can choose also both password systems, key and value. In this case,
if the user provides an incorrect sequence of keys, the display goes immediately to
the value password system.
The password number may be chosen by the user (personal) or it could be
used the number 2011, 2035 or 2036, according to the type of Indicator. Note that
the number 2011, 2035 or 2036 is always accepted by the value password system,
which helps the user in case he forgets his password. In order to enter a number for
password or for any other parameter use the Indicator front panel keys with the
following functions:

The Indicator has up to seven alarm devices: four of them are the outputs 1, 2,
3 and 4 used as alarm outputs which are relay 1, relay 2, relay 3 and relay 4 (see
figure 18). The other three devices are the couple of leds, LED 1 and LED 2, and the
display which can operate independently from the relays. In this case, the INDEP
option is selected. If the DEPEN option is selected for the leds and display, their
operation is associated to that of the relays.
Each alarm module can perform up to four types of alarm: low alarm for
channel 1, high alarm for channel 1, low alarm for channel 2 and high alarm for
channel 2. When configuring the seven independent alarm devices for the indication,
there are up to 28 setpoint alarms (SP) and their hysteresis (HYST).
Once the alarm configuration is established (CONF option), it is possible to
view or change only the values of alarm setpoints. Press the UP key while CONF
option is shown, in order to have a quick access to the setpoints of all alarms already
configured. The mnemonics of alarm setpoints have a code which is explained
through the two following examples:
1.H.r1
Channel 1 high-alarm setpoint associated to relay 1.
2.L.L1
Channel 2 low-alarm setpoint associated to led.
LATCHED - configures the relay to be deactivated only after the end of the
alarm condition and the operator has performed the acknowledge of this alarm. The
acknowledgment of the alarm condition is performed within the normal operation
mode by pressing the ACK key until it is shown the mnemonic corresponding to the
relay one is looking for. Note that it will be shown only the relays configured with latch
operation which require acknowledgment in order to return to normal state. After

Relay modules are provided with circuits for eliminating electrical arch (RC
snubber). The snubbers are put in parallel with the relay contacts, by placing the
jumpers J1 and J2 localized on the back of the relay board. When the jumpers are
not placed, the relay contacts are kept without snubbers. The relay module is sent
from factory with the jumpers placed.
Note the position of the jumpers in the following figure. Depending on the relay
board version, the jumpers may be on the front or rear side.
Jumpers 1 e 2
Fig. 24 - Jumpers for selection of snubbers on the relay board
Alarm and control relays are extremely critical in control and safety of
industrial processes. In order to ensure the expected relay behaviour, consider the
following two loading conditions.
• High currents circulating through the relay contacts (from 20mA to 3A). When the
relay switches high currents there is the occurence of elecrical arch which damage
quickly the relay contacts. Besides, electrical noise is generated. In these conditions,
it is recommended to use the RC snubbers which come with the relay module
(placed jumpers).
• Low currents circulating through the relay contacts (less than 20mA). The relays
could not function properly when the jumpers are placed. In this case, the snubbers
mantain a 4.5mAac/9.0mAac current when connected to a 120VAC/220VAC circuit.
This current is enough, in certain casses, to power a horn or alarm lamps, preventing
their deactivation. In this situation, there is no need to use the snubbers and the
jumpers must be removed.

Input Calibration
ys
DMY-2011, 2035 and 2036 Indicators are accurately calibrated in factory and
do not need periodic calibration in normal conditions. When calibration is required,
follow this procedure below.
Disconnect the process signals of I/O terminals.
Before calibrating the instrument, keep it turned on for at least 30 minutes for
warm up.
This section contains two parts: input calibration and output calibration.
pr
es
This section describes the procedure for calibration of input 1 and input 2.
The accuracy and precision of the calibrator used for generating references
must be at least two times better than the specifications of the Indicator.
The following tables list the references related to the type of input to be
calibrated. The left column shows the mnemonics presented on the display during
the calibration process.
Check if the internal input jumpers are properly placed.
To perform the calibration, enter level 5 of Calibration. The calibration level
has a password system which avoids someone to enter this level accidentally and
damage any calibration parameter. The password for entering this level is
number 5.
Once the correct password is provided, select the input type to be calibrated.
Choose the channel to be calibrated by pressing ENTER. The display shows the
mnemonics related to the references required for the calibration process. The
references must be applied before selecting the corresponding mnemonic shown on
display. When the reference is stable, start the calibration by pressing ENTER. At
this moment the Indicator begins the calibration process while the mnemonic CAL
blinks on the display.
While the display is blinking the reference must remain connect to the input
channel being calibrated.
When the display stops blinking and presents the mnemonic corresponding to
the reference, the calibration process of the first calibration point will be finished.
Change to the next reference and press DOWN to select another point.
Between any two calibration points wait 1 minute at least. After this time is elapsed,
press ENTER to start calibrating this point.
After performing all references on the table related to the input type to be
calibrated, the calibration process will be finished.
It is possible to calibrate only one point without rendering invalid the other
points already calibrated, in case the calibration of this point was not carried out
properly.
In order to return to normal operation move back through the hierarchical
levels until reaching level zero.

There are two steps for calibrating the thermocouple input. First, calibrate the
0 to 55mV input and the 0 to 5V input for the channel to be calibrated (terminals 2(+)
and 3(-) for channel 1 or 5(+) and 6(-) for channel 2) according to tables 6 and 7.
Once the mV calibrations are done, access the CJC mnemonic in the INPUT option
of level 5 for cold junction calibration.
The CJC mnemonic corresponds to the cold junction temperature of the
Indicator.
By pressing ENTER after the CJC mnemonic is reached the automatic
calculation of the cold junction temperature starts. Meanwhile the CAL mnemonic
blinks on the display.
After a few seconds, the program finishes the cold junction temperature
calculation and the display presents its value given in °C.
This value is a first approximation of the cold junction temperature. The user
must measure the temperature I/O terminals and correct the value presented by the
program following the same procedure for entering parameter values as explained on
section 3.2 of Configuration.
When these two steps are done the input calibration for any type of
thermocouple is accomplished.
Then return to normal operation mode moving back until level zero.
Calibration of 2 or 3-wire RTD input
In a 3-wire RTD input calibration connect precision resistances with the values
listed in table 10 to the channel to be calibrated (between terminals 1 and 2 with 2
and 3 short-circuited for channel 1 or between terminals 4 and 5 with 5 and 6 shortcircuited for channel 2).

shows the following error codes:
Err. 01 - RAM error
Err. 02 - E2PROM error
In case of RAM error, turn the instrument off and on to check if the error
message is displayed again. If the error remains, return the instrument to factory.
When there is E2PROM error, press the ENTER key and configure the
instrument again. Turn the instrument off and on to check if the error message is
displayed again. If the error remains, return the instrument to factory.
During configuration the display can show the Err.03 error message.
This error can happen when trying to assign a different configuration (analog
output, alarm or preset) to an output already configured and enabled. In order to
avoid this case, do not forget to disable relays 1 and 2 before enabling analog
output 1 and 2 and vice-versa.
Note: When configuring a relay module as an analog output, the relay
will be activated and deactivated continuously.

Instrument with the display out
Check if power supply voltage is provided to terminals 23 and 24 of the
Indicator.
Verify the integrity of fuse F1 of 2.0 A placed in the Power Supply Board as
shown in figure 21. Due to its package it is necessary to check the fuse continuity in
order to detect if it is broken.
Instrument malfunction
ys
Check if the Indicator is configured correctly by software and hardware
(internal jumpers).
Examine if the optional modules are connected in the right spots.
Check if the voltages on flat cable 1 as shown in figure 29 are close to the
values in table 12 and if they reach the CPU Board.
