MT-543Ri plus
1. DESCRIPTION
MT-543Ri plus has three outputs of temperature control and a internal buzzer. Because of its
versatility, it allows that the second stage works as alarm and the third, besides to work as cyclical timer,
it can work with the first stage in systems that need minimum ventilation.
Through the serial output RS-485, it permits communication with SITRAD software.
Product complies with CE (European Union) and UL Inc. (United States and Canada).

5. PARAMETERS DESCRIPTION
F01 - Access code: 123 ( one hundred and twenty-three)
To change the parameters is necessary use the access code. It is not necessary to use the access code
to visualize the adjusted parameters.
F02 - Offset indication
It allows to compensate eventual shunting lines in the reading of ambient temperature proceeding from
the exchange of the sensor or cable lenght alteration.
F03 - Operation mode of first stage
0 - Refrigeration
1 - Heating
F04 - Minimum setpoint allowed to the end user (first stage)
F05 - Máximum setpoint allowed to the end user (first stage)
Electronic limits whose purpose is prevent that too high or too low setpoint temperatures are regulated.
F06 - Control differential (hysteresis) of first stage
It is the difference of temperature(hysteresis) between turn ON and turn OFF the OUT1 output.
F07- Minimum delay to turn on the first stage output
It is the minimum time that OUT1 will keep turned off, it means, period between the last stop and the next
start.
F08 - Operation mode of second stage
0 - Refrigeration
1 - Heating
2 - Intra-range alarm (F09 and F10)
3 - Extra-range alarm (F09 and F10)
4 - Relative extra-range to first stage ( - F09 and + F10), It is considered the absolute
values of F09 and F10).
F09 - Minimum setpoint allowed to the end user (second stage)
F10 - Maximum setpoint allowed to the end user (second stage)
Electronic limits whose purpose is prevent that too high or too low setpoint temperatures are regulated.
When the second stage ( F08 ) is defined as alarm, the acting points are defined in F09 and F10.

F24 - Cyclical timer on trird stage- time on
It is the time that the timer will be turned on.
F25 - Cyclical timer on trird stage- time off
It is the time that the timer will be turned off.
F26 - Operation mode of cyclical timer
0 - Independent timer
1 - Timer started by the first stage setpoint
2 - First stage linked with cyclical timer (Timer starts on)
3 - First stage linked with cyclical timer (Timer starts off)
4 - Cyclical timer output turned on whenever the the first stage output is turned on
F27 -Operation mode of Buzzer
0 - Intra-range alarm (F28 and F29)
1 - Extra-range alarm (F28 and F29)
2 - Relative extra-range to first stage ( - F28 and + F29), It is considered the absolute
values of F28 and F29).
F28 - Acting point of Buzzer (inferior limit)
It is the inferior value of temperature to the buzzer alarm act as the configured Operation Mode of Buzzer
(F27).
F11 - Control differential(hysteresis) of second stage
It is the difference of temperature(hysteresis) between turn ON and turn OFF the output OUT2.
F12- Minimum delay to turn on the second stage output
It is the minimum time that the output OUT2 will keep turned off, it means, the space of time between the
last stop ant the next start. Only if programmed in F08 = 0 or 1.
F13 - Delay to enable the alarm when the instrument is powered on
During this time the alarm is kept turned off waiting that the system reaches the working control
temperature (only if F08 is set as alarm).
F14 -Reactivation time of alarm when inhibited manually
This function allows three different settings (only if F08 is set as alarm):
- The alarm is inhibited by an indefinite period or until the temperature range in normal
working condition and return the alarm again;
0 - The alarm can not be inhibited by facilitating access keys;
1 to 999 - The alarm will be inhibited during this period (in minutes), returning the call if the alarm
condition persists;
F15 - Alarm time (on cycle)
It allows to adust the time that OUT2 output will keep turned on (only if F08 is set as alarm).
F16 - Alarm time (off cycle)
It allows to adust the time that OUT2 output will keep turned off(only if F08 is set as alarm). To keep the
alarm always activated just set “0” in this function.
F17 - Operation mode of third stage
0 - Refrigeration
1 - Heating
2 - Cyclical Timer
F18 - Minimum setpoint allowed to the end user (third stage)
F19 - Maximum setpoint allowed to the end user (third stage)
Electronic limits whose purpose is prevent that too high or too low setpoint temperatures are regulated.
F20 - Control differential (hysteresis) of third stage
It is the difference temperature (hysteresis) between turn ON and turn OFF the output OUT3.
F21- Minimum delay to turn on the third stage
It is the minimum time that the output OUT3 will keep turned off, it means, the space of time between the
last stop and the next start. Only if programmed in F17 = 0 or 1.
F22-Time base of third stage cyclical timer
0 - seconds
1 - minutes
F23 - Activation time of third stage cyclical timer
This function depends of F26. Every time that the temperature reach the configured value in , the
configured time in this function is respected, to be activated the cyclical timer after. To activate the timer
when is reached just set “0” in this function.
F29 - Acting point of Buzzer (superior limit)
It is the superior value of temperature to the buzzer alarm act as the configured Operation Mode of
Buzzer (F27)
F30 - Buzzer time on
It is the time that the Buzzer will be turned on (cycle on). To turn it off the sonore alarm (Buzzer) adjust the
value “0” to this function.
F31 - Buzzer time off
It is the time that the buzzer will be turned off (cycle off). To turn it off the sonore alarm (Buzzer) adjust the
value “0” to this function.
F32 - Inhibition time of Buzzer during electrical supply
F33 -Reactivation time of Buzzer when inhibited manually
This function allows three different settings:
- The Buzzer is inhibited by an indefinite period or until the temperature range in normal
working condition and return the alarm again;
0 - The Buzzer can not be inhibited by facilitating access keys;
1 to 999 - The Buzzer will be inhibited during this period (in minutes), returning the call if the alarm
condition persists;
It is the time were the Buzzer will kept turned off even if in alarm contitions for a certain period after
startup, because the system has not yet reached working temperature.
F34 -
This filter aims at simulating an increase of the mass of sensor , thus increasing its response time
(thermal inertia). The larger the value adjusted in this function, the longest the response time of sensor.
A typical application requiring this filter is the freezer for ice cream or frozen goods, because when the
door is opened a hot air mass reaches the sensor directly, causing the indication of the measured
temperature to rise quickly and the compressor to be activated
F35 - Network equipment address RS - 485
Each controller connected to the RS-485 network must have its own address different from the others so
that the computer will be able to identify it.
Attention: To avoid communication problems, make sure that there are no controllers with the same
address.

IMPORTANT
According to the chapters of norm IEC 60364:
1: Install protector against overvoltage on the power supply
2: Sensor cables and signal cables of the computer may be joined, but not in the same electric conduit
through which the electric input and the activation of the loads run
3: Install transient suppresors (RC filters) parallel to the loads as to increase the product life of the
relays.

PROTECTIVE :VINYL
This adhesive vinyl (included inside the packing) protects the instruments against
water drippings, as in commercial refrigerators, for example. Do the application after
finishing the electrical connections.
Remove the protective paper
