This unit helps in optimizing the time that the genset is operational when he electricity is not there. The system works on the basic principle that specially in unmanned Shelters (or closed spaces) the AC compressor is not required to be run all the time. Normally, in unmanned locations the AC is run only to keep the equipment cool or recharge the batteries. Our system switches ON the genset only for that duration for which the AC compressor has to be switched ON. Thereafter, the genset is switched OFF. The specific functions are:
AC Mains
If AC mains is available then this unit bypasses itself as then there is no role for this unit.
Temperature
If the temperature rises above a preset point then the relay for the Contacts (C/NO/NC) operates. The relay keeps in this position till the temperature comes back within the limit. So effectively the generator shall be switched ON when there is a temperature above the specified limit. Then the Generator shall be switched OFF automatically when the temperature goes down. Adequate time lapse has been provided to avoid repeated start and stop of genset.
Voltage
If the voltage goes below the one selected on the panel then the relay for the Contacts (C/NO/NC) operates. The relay keeps in this position till the voltage comes back within the limit. So effectively the generator shall be switched ON when the voltage if below the specified limit. Then the Generator shall be switched OFF automatically when the voltage goes above the specified limit. Adequate time lapse has been provided to avoid repeated start and stop of genset.
Operation logic
 |
Check if the AC mains is there. If yes, don't do anything
|
|
Check Temperature. If above the specified limit, start generator
|
|
Check Voltage. If below specified limit, start generator
|
|
Continuously check Voltage and temperature. When Both within limits (temperature below the specified limit and Voltage above the specified limit) then stop the generator
|
Reset Switch
Reset Switch resets the operation of the system. If the generator is running on account of temperature or Voltage, on pressing the Reset switch, the generator shall be switched OFF. However, when the temperature goes above the specified limit NEXT TIME or Voltage falls below the specified limit NEXT TIME then the system becomes operational again. This facility has been specifically provided so that during maintenance etc. the technician can reset the operation but he need not Remember to Switch ON the system (as this is done automatically).
