The temperature inside the Walk-In incubator is controlled by intelligent programmable temperature controller and indicator. This controller is based on the microcontroller nano watt technology and its ergonomic design suits for any specific requirement of the incubator like Data logger facility, Thermal and DOT Matrix interface, direct data load facility in computer office automation software like MS-Word and Excel and many other features listed in the specification below.
1) Heater Mode : This LED indicates the heating system on condition and it light up when the set temperature is higher than the ambient temperature.
2) Cooling Mode: This LED indicates the cooling system on condition and it light up when the set temperature is lower than the ambient temperature.
3) Temperature Alarm: This LED indicated the extreme Ambient condition and the temperature failure condition.
4) Audio Alarm : This Alarm indicates the visual alarm and indiactes any failure and Temperature overshoot conditions.
5) Door Open : Visual indication with door open conditions.
6) A.C Power failure : This visual indicator light up when the mains power fail and the system working in the battery mode.
7) Low battery indicator : This LED indicates the battery backup status, This LED indicates when the battery charge capacity available at 25% of the total charge.
8) UP : Count up key.
9) SET : This is a set button to set any parameter on the screen, by pressing of this key a cursor blink on the corresponding parameter, So you can select any desired parameter and use UP and Down key to set specific value/setting.
10) Down : Down count key.
11) ESC : This key is used to exit from any menu, you are working right now.
12) Print/Data download : This key is used to transfer the stored data into the printer or Data download facility in the computer MS Excel/Word and Hyperterminal software.
13 ) Display Unit : This unit is a user intertractive interface system for easy operation and it displays the parameter like DATE, TIME, Ambient Temperature, Compressor ON Delay Time, Read and Set Temperature.
14) Temperature Display : This seven segment display indicates the read temperature value inside the chamber.
SYSTEM SETTING
1) DATE and TIME : From normal operational mode, press SET key ones,
The cursor blinks at
DATE (20), and for second press of KEY SET the cursor blinks at MONTH ( 12 ), and similary on Third press of key SET cursor blinks at YEAR and repeat the steps to move to any parameter.
Similary you move cursor on any parameter and set desired value for system operation.
To increase any parameter use UP key and to decrease any parameter use DOWN key.
After completion of all correct setting press ESC key to return back to the main menu.
