29. top command and then a further Start command has been received from the Transmitter This feature is useful when several pumps feed a common storage Tank using boreholes that have a limited water availability Mode 3 Single Run and Delay before Run selected Applications which use multiple Pumps at different locations to feed the same storage Tanks can be set to start at varying times i e Should the Main Pump not be able to fill the Tanks within a prescribed period when there is excessive water demand from the Tanks the second pump will start This is extendable to as many pumps as may be required Mode 4 50 Cycle Mode and Delay before Run selected This is a very useful configuration for Weak boreholes which are unable to provide sustained water delivery The Pump will cycle ON and OFF at a 50 rate as determined by the selected Time so as to prevent the borehole being depleted by continuous pumping The initial Pump Start is delayed by the selected Time following receipt of the Start Command from the Transmitter Mode 5 50 Cycle Mode and Instant Start selected Identical to Mode 4 above except that the Pump Starts immediately on receipt of the Start Command from the Transmitter Thereafter the Pump continues to cycle at a 50 ON and OFF rate as per the selected time until such a time as a Stop command is received from the Transmitter Pump protection is provided on the Receiver whereby shou
