Pulse Controlled Interval Timer – T1I_P
The SF1 Monitors negative phase sequence (NPS) voltage to detect phase failure, phase reversal and phase imbalance. The NPS voltage of the unit can be djusted from 7-15%. When any of these faults occur the unit will de-energize. The relay will only re-energize if the supply voltage corrects itself. The unit will not react to a balanced voltage variation
Microprocessor based pump protection relay capable of protecting a submersible pump against all major power line faults. The unit calibrates itself under normal running conditions and stores these parameters in non-volatile memory. The unit also incorporates a reset delay for under current situations to enable the borehole to replenish itself. In an over current situation the unit will retry three times to prevent permanent tripping with temporary blockages.
Microprocessor based two-shot timer with two selectable modes of operation and eight separately selectable ON and OFF time ranges from 0.3 sec - 60 hrs. The ON and OFF times can only be selected from the A or B range and not both.
Extensive applications due to combination of functions and time ranges. Due to the advanced design of the unit a high accuracy can be achieved. Any adjustment on the front potentiometers after the supply is applied is not acknowledged. This prevents unwanted changes of the time range.
The ON and OFF times can be adjusted independently.
