Cyclic Timers With Time Memory

This model is a cyclic timer incorporated to the Water level controller which is suitable for Borewells with limited water source.
In some places Borewells will pump water for few minutes ranging from 3 miutes to 30 minutes and after which it will stop pumping partaining to lowering of water table in the bore. The water table will resume after some time which again ranges from one hour to 10 hour. In such cases the pump has to be operated with required ON duration and OFF duration.

 

• The system Automatically controls pumping of water from Borwell with limited yield to Overhead Tank or Underground Sump.
• The system also provides Dry run protection to the Borewell Pump. ( i.e. when water is not being pumped into the Tank due to any reason).
•  The system can be programmed to set the ON duration to which the pump has to be operated.
• The system has three digit seven segment LED display of time and programming.
• There are only three push button membrane key switches for complete programming procedure.
• The system has built-in memory to store the status of operation and Programmed ON and OFF time duration.
• The system memory also stores the 'ongoing' ON and OFF time duration of the operation and in case of power failure, it continuous from the elapsed duration.
• The system memory is nonvolatile, i. e. it retains all the stored information even in case of power failure.
• The system provides Low voltage and High voltage protection and has Surge Voltage/Current Protection for the Pumpset.
• The system comes with Industrial Grade Electronic Components, Reliable Power Supply and Power Contactor in Plastic molded Panel Mounting Enclosure.
• The system is adoptable for any kind of starters of both Single phase and Three phase Motors.
• This system is suitable for Residences, Commercial complexes, Residential Apartments and Industries.
• The system has three position Power Control Toggle Switch with "Auto" mode, "Off" mode and "Manual" mode.
• In "Manual" mode the Pumpset can be controlled directly and level controller gets completely shutdown and bypassed.
• The system comes with Unconditional One Year Guarantee.

Cyclic_Timer_Systen

This device is basically a bell timer, which rings the Electric gong bell at set times for the preset programmed duration as per requirement. This is a cyclic timer which maintains the stored values of time in a built-in memory and repeats the cycle on programmed days at exact programmed times. This has a two line alpha-numerical display which will be continuously displaying the "current time" in 'HH:MM:SS' (i.e. Hour : Minute : Second) format with 12 hour mode.

The programming does not need any special skill and can be easily done by anybody with little common sense and programming information provided. The real time can be permanently stored in the system which will retain the time even in case of power failure. The bell times which are programmed will be stored permanently in a built-in special non-volatile memory chip. When bell rings at any programmed time the display will indicate the details of bell time for 10 seconds and then automatically changes over to display real time

The System has Following Features:

• Two line Alpha-numerical display with intelligent back light facility.
• There are only five push button membrane key switches for complete programming procedure.
• Security lock-switch to avoid unauthorized editing of program.
• Provision for long and short duration ringing of bell. (Programmable Bell duration)
• Provision for week programming, which automatically switches OFF the timer on Sundays and takes different times for Saturdays (if there is any).
• Continuous Display of NEXT BELL timing of that particular day.
• Most advanced “Program Watch Dog Technology” to ensure trouble free operation.
• The Timer retains the set timings in memory even in case of power failure.
  
• Rugged industrial grade Plastic molded enclosure with angled front panel.
• CAD designed industrial grade electronic Multi layer circuit board.
• 10A Relay Contactors incorporated to handle any numbers of powerful electric bells.
• Models availablewith 20 Programs and 40 Programs storing capacity.
• Provision to operate the electric bell manually in cases of emergency.
• Facility for ‘custom built system modifications’ to suit individual requirements.
• 230 V AC power supply with very nominal power consumption.
• The system has unconditional TWO Year Guarantee.
