Model : Cyclic Timer and PFR - Type: 5 digit

This product is a timer that will periodically turn ON and OFF your 3 Phase Submersible pump based on the timings adjusted by the user. The ON time or the running time is the total time for which the motor is supposed to turn ON in a cycle. The OFF time or the waiting time is the total time for which the motor should wait. The OFF time is also the recharge time if the water level in the borewell is low. The task of the cyclic timer is to turn ON the motor for the set ON duration and keep the motor in the OFF state for the set OFF time. After the set OFF time is up, the motor will again be switched to the ON cycle and so on. The advantage of having the cyclic timer and PFR is that the motor is allowed to run only if the 3 Phase supply is present.

Operation:
    The timer display powers up as soon the power supply is ON. The timer displays the set ON time and OFF time for set power ON Delay during power ON. The ON time and OFF times are displayed in all 5 digits. The first 3 digits from the left hand side (red color) will be Minutes in MM:SS model and Hours in HH:MM model respectively. The fourth and fifth digits from the left hand side (green color) will be seconds in MM:SS model and minutes in HH:MM model respectively.The timer will resume its operation from where it had previously stopped. The blinking of the LED determines the current cycle the timer is in. If the led blinks in the fifth digit, that means the timer is currently in ON cycle and if the led blinks in the third digit, the timer will be in OFF cycle respectively. The numbers against the blinking digit indicates the elapsed time. For the whole time, the timer is in a particular cycle, the other cycle will display the set time. The timer hence shuffles between the ON and OFF cycles one after the other.
