1 - Introduction
1.1 - Description
The PRESYS TY-2090 Transmitter is a microprocessor-based instrument which
receives any process variable found in industrial plants as: temperature, pressure, flow,
level, etc. It has non-volatile internal memory (E2PROM) for storing calibration values.
It can communicate with computers through the optional Communication Module
RS-232 or RS-422/485.
The Transmitter is capable of monitoring two
universal standard inputs, accepting direct connection of
thermocouples, RTDs, current (mAdc) and voltage
(mVdc and Vdc). The thermocouple and RTD inputs are
automatically linearized by means of tables stored in the
EPROM memory. A 24 Vdc voltage source, output-
isolated and with short circuit protection, is provided to
power the standard field two-wire transmitters.
The type of input chosen by the user is enabled by
jumpers and by configuration via software. All
configuration data can be protected by a password
system, and are stored in the non-volatile memory in
case of power failure.
The Transmitter has been designed with basis on
modularity concept and accepts up to 4 output cards.
The possible output types are: analog, SPDT relay, solid-
state relay and open collection voltage. Outputs are
electrically isolated from inputs.
Fig. 1 - Front view of
TY-2090 Transmitter
It allows universal power supply from 90 to 240 Vac.
The instrument is housed in an extruded aluminum case which makes it highly
immune to electrical noise, electromagnetic interference, and resistant to the most severe
conditions of industrial usage.

2 - Installation
2.1 - Mechanical Installation
The TY-2090 Transmitter can be mounted on a surface or on all types of existing
DIN rail, as illustrated in the figure below.
Fig. 2 - Dimensional drawing and detail of the adapter for DIN rail
2.2 - Electrical Installation
The TY-2090 Transmitter can be powered with any voltage between 90 and 240
Vac or Vdc. Note that power is always applied to the internal circuit when the instrument is
connected to the AC supply.
Connections of process input and output signals should only be made with the
power off.
Figure 3 shows the instrument I/O terminal scheme with all designations for power
supply, grounding, communication and process input and output signals.
Signal cables should be kept as far away as possible from power supply cables.
Since the instrument housing is a metallic case, it is necessary to connect the
instrument ground terminal (gnd earth) to the local earth ground; this terminal should never
be connected to the neutral terminal.

Fig. 3 - Transmitter terminals
2.3 - Process Input Signal Connection
The Transmitter, in its two standard universal inputs, can be connected to
thermocouples, 2 or 3-wire RTDs, mA, mV or V. In order to know the input sensor types
refer to Table 1, section 1.3 on Technical Specifications.
The enabling of a certain type of input sensor is obtained by means of internal
jumpers (refer to section 4.2, Hardware Configuration) and by proper sensor selection in
configuration time (refer to section 3.2, Configuration). Therefore, the connections
explained below, will only become effective if the instrument is correctly configured in
terms of hardware and software.
The wiring of a type of sensor to input 1 does not restrict the simultaneous use of
another sensor, of the same type or different type, for input 2.
In order to prevent noise induction in the wire connecting the sensor to the I/O terminal,
use twisted pair cable and run the sensor connection wires through a metallic conduit or
use a shielded cable. Be sure to connect only one shielded wire end to the negative I/O
terminal or to the sensor ground, as outlined in the following items.
WARNING: THE GROUNDING OF THE TWO SHIELDED WIRE ENDS MAY CAUSE
DISTURBANCE TO THE TRANSMITTER.

2.3.1 - Thermocouple Connection
Whenever using just one thermocouple, the user should preferably connect it to
input 1 of the Transmitter, in order to obtain greater accuracy, since the cold junction
sensor is solidly attached to the I/O terminal and closer to input 1.
In order to reduce cold junction compensation error, apply thermal paste from the
I/O terminal to the cold junction sensor.
Connect the thermocouple to terminals 2 (+) and 3 (-) in order to use the input 1, or
connect to terminals 5 (+) and 6 (-) to use the input 2, as shown in figure 4.
Use compensation cables of the same construction material as the thermocouple to
connect the thermocouple to the Transmitter I/O terminals. Check that the thermocouple
polarity is the same as that of the I/O terminals.
Fig. 4 - Thermocouple Connection
2.3.2 - RTD Connection
The RTD can be connected to 2, 3 or 4 wires. All connection types are shown in
figure 5.
For 2-wire RTD, connect the RTD between I/O terminals 1 and 3 to use input 1, or
to terminals 4 and 6 to use input 2, as illustrated in figure 5.
For 3-wire RTD, connect the RTD in the same way as described for a 2-wire
connection, and connect the third wire for RTD compensation to terminal 2 in case of input
1, and to terminal 5 in case of input 2, see figure 5.

A 4-wire RTD is connected to the Transmitter in the same way as a 3-wire RTD,
except that the fourth wire is disregarded and left disconnected, see figure 5.
A 3-wire RTD provides greater accuracy than a 2-wire RTD.
The RTD wiring should be of the same material, length and gauge to ensure proper
resistance compensation of connecting wires. The maximum resistance of connecting
wires is 10 per wire. The minimum gauge should be 18 AWG for distances up to 50
meters and 16 AWG for distances superior to 50 meters.
Fig. 5 - RTD Connection
2.3.3 - Milliampere Input
A standard current source of 4 to 20 mA can be applied between terminals 1 (+)
and 3 (-) in case of input 1, and between terminals 4 (+) and 6 (-) in case of input 2. Such
current can be originated from a transmitter with external power supply.

If the Transmitter internal voltage source of 24 Vdc is used to power a 2-wire
transmitter, the current is received only by terminal 1 (+) in case of input 1, and it is
received only by terminal 4 (+) in case of input 2. Figure 6 illustrates both possibilities of
connection.

For outputs 3 and 4 there are three different output types: SPDT relay, open
collector voltage and solid-state relay. Figure 8 shows the Transmitter outputs.
Notice that the I/O terminals will only show output signals if the corresponding
optional module is installed and the output is correctly configured. In case of analog
outputs, refer to sections 3.2, Configuration, and 4.3, Optional Module Connection, for
details on installation and configuration of optional modules.
(*) Relay contacts assume that SAFE condition (see section 3.2 on Configuration) was selected for relays
and that the Transmitter is powered and is under non-alarm condition. With no power supply or under alarm

2.6 Communication
The TY-2090 Transmitter can communicate with computers via RS-232 or RS-
422/485 provided the optional communication module is installed and the proper
communication parameters are configured via software.
Specific information about communication and signal connection can be found in
the Communication Manual.
3 - Operation
3.1 - Normal Operation
The TY-2090 Transmitter has two operation modes: normal operation and operation
in configuration time.
In normal operation the Transmitter retransmits the process variable to a remote
point either through its two analog outputs 1 and 2, or via RS-232 or RS-422/485
communication. The analog outputs 1 and 2 can retransmit input 1 as well as input 2. The
two analog outputs can even retransmit the same input. Moreover, the Transmitter checks
the alarm conditions and activates the alarm outputs 3 and 4 if it is the case.
The Transmitter has a portable configuration unit, MCY-20, which is connected to it
by means of a DB-25 connector, as illustrated in figure 9 below.
PRESYS MCY - 20
Fig. 9 - MCY-20 Portable Configuration Module
presys

PRESYS | Instruments TY - 2090
Operation
Page 15
When the MCY-20 Configuration Module is connected to the Transmitter under
normal operation, the instrument begins to function as a transmitter and as a process
monitor as well, through the Module display.
Under configuration time operation mode the user, through the MCY-20
Configuration Module, selects and assigns values to the parameters which regulate the
Transmitter functioning, when in normal operation. Such parameters are, among others,
alarm set-point values, retransmission output range, etc.
The normal operation mode, in which the Transmitter operates most of the time, will
be named level zero. At this level, the keys on the MCY-20 Configuration Module front
panel have the following functions:
ENTER
Key
Switches from level zero to level 1 or asks for the
password, depending on the configuration.
DOWN
Key
Changes the channel shown on display. If the display was
showing channel 1 (2), after pressing the DOWN key, the
display changes for the measured variable of channel 2
(1).
3.2 - Configuration
To gain access to the configuration mode, one should match the password
established with the purpose of preventing unauthorized people from altering the critical
parameters of the process.
Therefore, whenever the ENTER key is pressed under normal operation mode, one
of the following cases might occur:
i) Enter directly into level 1 (GENERAL) of configuration mode, indicating that the
instrument was not configured with the password system.
ii) The Module display shows the PASSWORD warning, indicating that the instrument has
a password system by key or by value, as illustrated in figure 10.
presys

PRESYS | Instruments TY - 2090
Page 16
Fig. 10 - Password system by key and by value
In case of password by key, the user should press the UP, DOWN and ENTER keys
in sequence to enter the configuration levels.
In case of password by value, the user should press the ENTER key a second time
to obtain the number 00000, with the last digit blinking on the right. The blinking digit
indicates the position where the digit of a 4-digit number will be entered by the user. In
order to move to the next digits on the left, the user should press the ENTER key. After
entering all digits, the user can press the ENTER key once more to switch to level 1 in
case the password is correct, otherwise the system reverts to normal operation ( see
figure 10).
The user can even select both password systems, by key and by value. In such
case, if upon receiving a request for a password the user enters a wrong key sequence, he
will be immediately reverted to password by value.
The password can be a number chosen by the user (customized) or the number
2090. Notice that in case of password by value the number 2090 is always enabled,
serving as a help to the user in case he forgets his password. In order to enter a password
number or any other parameter value, the user can use the front Module keys, which have
the following functions:
UP
Key
Increases the digit
DOWN
Key
Decreases the digit
ENTER
Key
Moves to digit on the left
All configuration parameters are stored in the non-volatile memory and determine
the instrument normal operation. Through such parameters the user can adapt the
instrument according to his requirements, if he desires to change the factory configuration.

Level 1 - General
In level 1 we have the options: TAG, SOFT, PASSWORD and INDIC (see figure
12).
TAG - Enables an alphanumeric identification for the instrument. The procedure
used to enter a TAG or any other parameter is the same as for the previously described
password (see the functions of ENTER, UP and DOWN keys under password by value).
SOFT - Shows the software version number.
PASSWORD - Allows whether to define or not a password system to access the
configuration mode. The password system can be defined by key, by value (number
chosen by the user and the number 2090) or both. The key sequence for defining a
password by key is, as explained above, to press the UP, DOWN and ENTER keys in that
order.
INDIC - Within the option for the indication of the variable measured on display of
MCY-20 Module, it is possible to view the values related to channel 1 and channel 2 by
pressing the DOWN key or allowing the instrument to toggle between the measured
variable values of each channel. In the first instance, NO is selected for option TWO, and
in second instance, YES (automatic scanning mode) is selected for option TWO, together
with the display time, in seconds, assigned to each channel.
