INSTALLATION DATA

ENTRY
The EasyCoreC400 module has been designed to measure temperatures from up to 4 external measurement probes. The device converts the temperature measurement(s) into a current signal that is calculated based on the average, minimum or maximum value of the active temperature channels. Measurements are recorded in the module memory and transferred to an external database system via the RS485 interface.

OPERATION DESCRIPTION

The recorder has 4 measurement channels to which PT100 sensors or “J” and “K” thermocouples can be connected.
The device has a digital input “DI”, which indicates the start and end of recording in “Process” mode, and a digital alarm output , used to signal errors related to disturbances in temperature measurements, RTC, etc..
Configurable analog output 0 ÷ 20 mA / 4 ÷ 20 mA, which displays temperature values depending on the set source and type.
RS485 communication port used for communication with dedicated software on a computer.
The contents of the recorder’s memory (for archiving purposes) can be transferred to a computer using dedicated software. When the memory is full, the oldest samples will be overwritten with new ones.
The built-in graphic display (OLED) enables local visualization of measurements and alarms and facilitates operation of the device.

KEYBOARD WITH DISPLAY

KEYBOARD DESCRIPTION
The keyboard consists of 4 buttons:

“Back/Exit” is used to exit the settings without saving them
“Down” – the button is used to navigate and select a lower value
“Up” – the button is used to navigate and select a higher value
“Enter/OK” – button used to enter the settings and confirm and save changed values

Caution
When configuring module parameters using the button we exit without changing the settings, while holding saves the value.

DISPLAY DESCRIPTION

Using button we open the information screen: Pressing again we open a screen with configuration information:

CONFIGURATION FUNCTIONS (MENU)

To enter the MENU, press button from the main screen. The entrance to the module settings is password protected. By default it is 00000, the password should be changed in the settings, as described in MENU/Settings/Password

SENSORS
The module has 4 analog inputs to which measurement probes can be connected. Each input corresponds to the following measurement channel:

AI1 -> Ch1;

AI2 -> Ch2;
AI3 -> Ch3;
AI4 -> Ch4

To ensure proper operation of the device, the following parameters must be configured:

• Name” – sensors name
„Type” – selection of the sensor type:
- Pt100 – resistive;
- TC-J – J type thermocouple;
- TC-K – K type thermocouple.

„Status” – the selected measurement channel may have two statuse:
- Active – the displayed measurement is involved in conversion to current value and alarm state;
- Inactive – the displayed measurement does not take part in the conversion to current value and alarm states.

“Offset” – correction of the measured temperature from -10 °C to +10 °C with a resolution of 0,1 °C

OUTPUTS
The device has one analog output AO1 and one digital output DO.
The AO1 output is used to output a current signal based on the measured temperatures. The DO output is a voltage output used to signal alarm states.

CONFIGURATION OUTPUT AO1
For the correct operation of the analog output, the following parameters must be configured:

„Type” – operating range 0 ÷ 20 mA or 4 ÷ 20 mA ;
„Source” – defines the method of calculating the value of the output current signal. For all calculations, only the measured temperatures of active sensors are taken into account:
- “Channel” – the displayed current value will correspond only to the measured temperature value on the selected channel
- „Min” – the displayed current value will be the value corresponding to the lowest read temperature;
- „Max” – the displayed current value will be the value corresponding to the highest temperature read;
- “Average” – the displayed current value will correspond to the average value of the measured temperatures;

„Scaling” – assigning a temperature value corresponding to the values of the output current 0/4 mA and 20 mA. The scaling range is from -200 °C to 500 °C.

CONFIGURATION OUTPUT DO ALARM
The module allows you to signal the lack of temperature measurement on active measurement channels by energizing or losing voltage at the DO alarm output.
Parameters enabling output configuration:

„Delay” – delay in seconds after which the output is to react after the occurrence of an alarm event;

„Act. Lvl” – voltage level of the active alarm “0 V” or “+24 V”;
“No meas.” – alarm triggered when:
- „Any” – no measurement on any measurement channel;
- „All” – no measurement on all measurement channels;
- „Off”- alarm off.

Additionally, the module, through the DO output and a message on the screen, informs about such errors as:

damage to internal memory;
clock incorrectly or not set.

INPUTS

CONFIGURATION INPUT DI1
DI1 is a binary input. Applying or losing voltage to the input causes the module to start or stop recording the measured temperatures.
Triggering the registration process via input must be previously defined in the registration configuration (MENU/Regist.).
The following parameters are configured for the DI input:

„Delay” – delay in seconds after which recording is to start, from the appearance of the activation signal;
„ Act. Lvl” – signal level activating registration “0 V” or “+24 V”.

SETTINGS

RS485
Configuration of transmission parameters RS485:

“Address” – the address of the device in the network;

„Baudrate” – data transmission speed;
„Parity” – parity bit setting, selectable:
- “None” – no parity bit;
- „Odd” – the total number of 1s in the data is odd;
- „Even” – the total number of 1s in the data is even;
„Stop Bit” – setting the stop bit between frames “1” or “2”

Using button we exit without changing the settings, while holding saves value.

UNIT
In the module, you can set one of two units in which the temperature will be displayed:

„°C” – Celsius

„°F” – Fahrenheit

PASSWORD
Menu allowing you to change the current access password:

Button and are used to select a digit;

Button is used to exit without remembering the password;
Button is used to select the digit to be modified, and holding it will remember the new password.

LANGUAGE
Menu for changing the displayed language:

Polish
English
Russian

Romanian

The choice of supported languages depends on the current software version.

REGISTRATION
The module allows you to save measurement records in the internal memory, which can later be read using the dedicated MPC4 software.

„Frequen.” (Frequency) – a parameter specifying how many units the sample will be saved.
The range can be set from 1 to 59;
„Type” – method of triggering the start of registration:
- “Process” – recording starts after applying a signal to the DI input, in accordance with its configuration in point CONFIGURATION INPUT DI1;
- “Cont.” (Continuous) – recording takes place continuously, regardless of the signal supplied to the DI input.
„Unit” – specifies the unit of time in which samples will be saved.
Possible to set: Seconds, Minutes, Hours.

CLOCK

Buttons and we choose between:

Date:

Button and are used to select a digit;

Button is used to exit without remembering the date;
Button is used to select the modified digit, and holding it saves the new date.

Time

Button and are used to select a digit;
Button is used to exit without remembering the date;
Button is used to select the modified digit, and holding it saves the new date.

INITIALIZATION
Using this function restores all settings and parameters to default.
The address where the last sample was saved will also be reset, which means that the recording will start from the beginning of the memory and all data from the zero address will be lost.

CONNECTION TO A PC

To connect the recorder to a PC, use a USB-485 converter. It is recommended to use the MCU-01 converter from MIKSTER. The converter should be connected to the device on the port (marked “RS485”) with a 2-wire cable in the following places:

A (Converter) -> A (Recorder)

B (Converter) -> B (Recorder)

The computer will install the drivers needed for the device to work properly.
If the computer does not find the appropriate driver, install it from the CD included with the converter, or download it from the website www.mikster.eu in the Software section.

CONFIGURATOR EASY CORE

The Easy Core Configurator program allows you to configure the module using a PC. Additionally, the software displays current readings and information about the connected module.
To configure, connect the module to a computer using a converter via the RS485 line.
Software available for download at www.mikster.eu
