Introduction

1.0 - Introduction
1.1 - Description
The TY-2090-Energy transmitter is ideal for security applications in turbines,
hydroelectric plants and thermoelectric generators. It is a microprocessor-based
instrument which receives any process variable found in industrial plants such as:
temperature, pressure, flow, level etc. Ithas a non-volatile internal memory (E2PROM)
for storing calibration values.
It can communicate with acomputer through an optional RS-232 or RS-422/485
Communication Module. The Transmitter is capable of monitoring two
universal standard inputs, accepting direct connection
of thermocouples, RTDs, current (mAdc) and voltage
(mVdc, Vdc). The RTD inputs are automatically
linearized by means of tables stored in the EPROM. A
24 Vdc power supply,isolated from the output and
with short circuit protection, is provided to power up
standard field two-wire instruments.
The type of input selected 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.
Designed within the concept of modularity, the
transmitter accepts up to 4 output cards. The possible
output types are analog, SPDT relay, SPST relay,
solid-state relay and open collection voltage.
In case of input sensor breaking, the trip alarms
are not triggered (configurable for 4-20 mA and RTD
inputs) and the analog outputs assume preconfigured
safety values. The alarm outputs can be
independently configured to work in latch mode,
demanding the acknowledgement by the operator
through the MCY-20 configurator keys or via
communication in order to be disabled after the
return of the process variable to the normal
condition. The outputs are electrically isolated from
the inputs. In addition to the high and low alarms, the
transmitter can be set for failure alarms (watchdog) triggered by the detectionof broken
sensors connected to the current or RTD inputs.
It allows the use of a universal power supply from 75 to 264 Vac 50/60Hz or 100
to 360 Vdc (any polarity).
The instrument has an extruded aluminum case which makes it highly immune to
electrical noise, electromagnetic interference and resistant to the most severe conditions
of industrial usage.

2.3 - Process Input Signal Connections
The Transmitter, in its two standard universal inputs, can be connected to 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 selection of a certain type of input sensor is enabled by means of
internal jumpers (refer to section 4.2, Hardware Configuration) and by aproper
selection of the sensor 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: GROUNDING TWO SHIELD WIRE ENDS MAY CAUSE NOISE IN

2.3.1 - RTD Connections
The RTD can be connected with 2, 3 or 4 wires. All connection types are shown in
figure 4.
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 4.
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 4.
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 4.
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 greater than 50 meters.

2.4 - Output Connections
The Transmitter, in its most complete version, can be provided with up to four
output signals: output 1, output 2, output 3 and output 4. Outputs 1 and 2 are used as
retransmission outputs or alarm outputs. Outputs 3 and 4 are used only as alarm
outputs.
In case of outputs 1 and 2, there are six different output types, which can be
obtained between I/O terminals: retransmission output (4 to 20 mA, 0 to 5 Vdc or
0 to 10 Vdc), SPST relay, open collector voltage and solid-state relay.
For outputs 3 and 4 there are three different output types: SPDT relay, open
collector voltage and solid-state relay. Figure 7 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 on Configuration and 4.4 on
Optional Module Connection for details on installation and configuration of
optional modules.
The state of the relay contacts illustrated in Figure 7 assume that the
instrument is powered off. When powered on, the status (open or closed) depends

Operation
Page 14
3.0 - Operation
3.1 - Normal Operation
The TY-2090-Energy 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 8 below.
Fig. 8 - MCY-20 Portable Configuration Module
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 setpoint values, retransmission output range, etc.

In the operation mode it is possible to re-enable the trip alarms configured with failure
manual reset (see section 3.2 - Configuration: Level 3- Alarms) by following the procedure
below:
(i) The display shows a blinking B.OUT.1 / 2 mnemonic (for channel 1 / 2 with RTD
input) or the BRK.1 /2 mnemonic (for 4-20 mA current input), indicating that the sensor is
broken and the TRIP alarms are disabled;
(ii) Reconnect the sensor to the instrument terminals;
(iii) The display shows alternatively the indication value and the RL.OUT mnemonic
(relays 3 and/or 4 disabled);
(iv) Enable the relays with TRIP alarms according to the steps below:
1. Press the UP key during the exhibition of the process variable in order to
show the mnemonic of the disabled relay (R.3.OUT or R.4.OUT);
2. Press ENTER;
3. The R.3.OUT or R.4.OUT mnemonic disappears;
4. The display shows the next disabled relay mnemonic, if present, or the
mnemonics for the power up event (AC.P.UP), failure alarm (AC.CH.1 or
AC.CH.2) or for the relay alarms (AC.RL.1 to AC.RL.4) which require
acknowledgement in order to return to normal state (latch condition).
In order to pass to the next mnemonic without re-enabling the trip relay or
acknowledging an alarm relay under latch condition, one must press the UP key once again.
After all available mnemonics are shown, the display returns to the process variable
indication.
Note: If both relays 3 and 4 are disabled, relay 3 will be re-enabled first (by pressing ENTER
for the R.3.OUT mnemonic) and then relay 4 is re-enabled (ENTER for the R.4.OUT
mnemonic).

3.2 - Configuration
To have access to the configuration mode, one should provide the password
configured 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 a 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 09.
Fig. 9 - 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 9).
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:
