1. DESCRIPTION

2. APLICATIONS

The MT-543e Log controller has four stages that can be applied to refrigeration or heating: the first

stage, together with the third stage, works in systems that require minimum ventilation; the third one

works as a cyclical timer; the fourth one works as an alarm. The second, third and fourth stages work

also in the following modes: refrigeration, heating, refrigeration (Sp1), heating (SP1) and refrigeration in

rotation. It also has a fifth relay that can be used as power failure alert and / or alarm.

The MT-543e Log accepts three types of sensors: NTC thermistor (-50 to 105 °C*), PT100** and

PT1000** (-99 to 300 °C). It has an intelligent functions lock system, a mode to switch off the control

functions, an internal audible alarm (buzzer), and a configurable digital filter.

It allows the stages to be used in an independent way or in rotation mode (alternating the outputs). It

features an internal memory (datalogger), where the temperature value is stored in user-defined time

periods, the temperature variation and the state of the outputs. In addition, it has built-in rechargeable

battery and clock to keep track of data even in case of power failure and serial port for communications

with Sitrad.

It also allows monitoring of HACCP critical points (Hazard Analysis and Critical Control Point) by means

of records in the controller's memory of high temperature alarm, power failure, and digital input.

Note: Sensor cable length can be increased to up to 200 meters by the user by using a PP 2 x 24 AWG

cable.

*It measures temperatures up to 200 °C using the SB59 (sold separately).

**This sensor is sold separately.

- Stage 1 linked to the cyclical timer (timer off upon power up) (F22=3): The operation is similar to the previous configuration. The difference in this configuration is that the timer starts off. - Cyclical timer output is on whenever stage 1 output is on (F22=4): in this operating mode timer cycles according to the times configured in F20 ([COn]) and F21 ([COff]), and stage 3 stops cycling and keeps the output switched on, whenever stage 1 output switches on, as shown in Figure 3.
PAGE 4
High temperature alarm [AlHi] During operation, when a temperature exceeding the value configured in F60 (HACCP - High temperature alarm) is identified and stays above this value for a time exceeding the value configured in F61 (Alarm validation time), an [AlHi] type record is created. In this case, the information stored is: alarm start's date and time, alarm duration, and maximum temperature measured during the alarm condition.
PAGE 5
6.4.5 Internal datalogger When the datalogger is enabled (F62), it is possible to store records in the controller's internal memory. It can be configured to store records by time interval (F63), by temperature variation (F64), and/or by the variation of the state of the digital output or inputs (F65).The activation of alarms also performs the storage of records. The information contained in a record are: temperature, state of the outputs, state of the door, alarms and record creation timestamp.

.5.1 Description of the parameters F01 - Controller's operating mode: Configures if the controller operates in the basic mode (45 functions) or in the advanced mode (61 functions): [,,,0] - Basic mode [,,,1] - Advanced mode NOTE: The features of the advanced mode will be disabled when the controller is in the basic mode. F02 - Indication offset: Allows for the compensation of possible deviations in the temperature reading caused by the replacement of the sensor or changes in the cable length.

F43 - Time for functions lock: It configures the time in seconds for the command to activate the functions lock: [,,15] to [,,60] - Time in seconds for the command to activate the lock. F44 - Control functions shutdown: Authorizes switching off the control functions (see item 6.3.7). [,,,0]- Disables the control functions shutdown. [,,,1]- Enables activation/deactivation of the control functions only if the functions are unlocked.
