SERIAL COMMUNICATION

Ver.04

E251415

MT543V04-07T-12178

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).

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).

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.

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).

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

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.

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;

Intensity of the digital filter

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.
