THREE OUTPUT DIGITAL CONTROLLER

WITH ALARM, CYCLICAL TIMER AND

SERIAL COMMUNICATION

Ver.01

1 - DESCRIPTIONMT-543Ri LOG has three outputs of temperature control and a internal buzzer. Because of its versatility, it allows that the second stage works as clyclical timer and the third as alarm, the second stage can work with the first stage in systems that need minimum ventilation. The unit is equipped with a clock and an internal memory (datalogger). The MT-543Ri LOG can store the temperature data for certain periods of time, temperature variations and events such as sensor error, alarms and output changes. It also has an internal rechargeable battery that permits data recording even during a power outage.Through the serial output RS-485, it permits communication with SITRAD software.

-

-

- 7.2 Viewing current date and time:You can press the key shortly to view the date and time set in the controller. The display shows the current day, month, year, hours and minutes, in this order. Ex: 03/17/2006 12h43min

F22 - Delay to enable the alarm when the instrument is powered onDuring this time the alarm is kept turned off waiting that the system reaches the working control temperature (only if F17= 4,5 or 6).

F23 -Reactivation time of alarm when inhibited manuallyThis function allows three different settings (only if F17= 4,5 or 6):

- The alarm is inhibited by an indefinite period or until the temperature range in normal working condition and return the alarm again;

- The alarm can not be inhibited by facilitating access keys; to - The alarm will be inhibited during this period (in minutes), returning the call if the

alarm condition persists;

F24 - Alarm time (on cycle)It allows to adust the time that OUT3 output will keep turned on (only if F17= 4,5 or 6).

F25 - Alarm time (off cycle)It allows to adust the time that OUT3 output will keep turned off (only if F17= 4,5 or 6).

F26 - Enables F24 and F25 on easy access menuEnables the time setting alarm ON and OFF in the easy access menu, if the 3rd stage is configured as an alarm (F17=4, 5 or 6).

- Disabled- Enabled

F27 -Operation mode of Buzzer - Intra-range alarm (F28 and F29)

- Extra-range alarm (F28 and F29) - Extra-range alarm relative to the 1st stage setpoint ( - 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 onIt 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 offIt 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 alarm will kept turned off even if in alarm contitions. It serves to inhibit the buzzer during the time while the system do not reaches the working control temperature.

F33 -Reactivation time of Buzzer when inhibited manuallyThis 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;

- The Buzzer can not be inhibited by facilitating access keys; to The Buzzer will be inhibited during this period (in minutes), returning the call if the

alarm condition persists.-

F34 - Time for the open door alarm When the door open alarm is enabled, the buzzer will be triggered after the door has been left open for the programmed amount of time. The time the buzzer is on and off is set with F30 and F31.

- Disabled to - Minutes to activate the open door alarm

F35 - Digital input operation modeThis function allows to configure what status of digital input will indicate that the door is open:

- Closed contact indicates that the door is open- Open contact indicates that the door is open

F36 - Datalogger operation mode Allows to choose between the following operation modes of the datalogger:

- Always OFF- Always ON- Manual operation

F37 - Datalogger sampling interval Time period in which the controller will register a sample of the temperature and the control outputs status.

F38 - Variation of the temperature to force data recording Temperature difference to forces the recording of data in the memory, independently of the sampling time configured at F37. To desable this function, just decrease the value until the message appears in the display.

F39 - Variation of the outputs to force data recording Indicates whether the change in the control outputs (configured as cooling or heating) will force the recording of data in memory regardless of the time of sampling set in F37. Data recording will also occur if the device enters or exits the alarm condition (for OUT3 and buzzer) and lack of and return electricity (if the battery is connected as described on item 10.1)

- OFF- ON

F40 - Overwrite records in the memory when it is full This function indicates whether the controller should start writing the new data at the beginning of the datalogger's memory when it is full. This prevents that the latest data recorded from controller be erased first.

F41 - Intensity of the digital filter 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 unnecessarily.

F42 - Network 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.

ENVIRONMENTAL INFORMATIONPackage:The packages material are 100% recyclable. Just dispose it through specialized recyclers.

Products:The electro components of Full Gauge controllers can be recycled or reused if it is disassembled for specialized companies.

Disposal:Do not burn or throw in domestic garbage the controllers which have reached the end-of-life. Observe the respectively law in your region concerning the environmental responsible manner of dispose its devices. In case of any doubts, contact Full Gauge controls for assistance.

10.3 - Data recording in the event of a power outageWith the battery connected, as described in item 10.1 and the datalogger activated, the MT-543Ri LOG will record the temperature in the internal memory even in the event of a power outage. These records can be configured to be recorded at preset time intervals (F37) and/or with the temperature variation (F38). If the temperature variation data record is disabled, the device will read the temperature sensor only at the set time intervals, therefore using less energy. With the temperature change recording activated, the sensor will be constantly read, using more energy, but recording all the details of the temperature variation.

10.4 - Battery Precautions- Avoid unnecessarily draining the battery;- If the appliance is not in use, the battery should be disconnected;- If a greater time interval between each sample is set, the datalogger will use less battery power;- If not required, disable the F38 function to avoid wasting the energy used in reading the temperature sensor.
