This is an application which consists of 3 pumps circulate per 2 a 4th filter pump and a 5th waste water pump for controlling a fountain. The application was developed with Zelio Logic SR2B201FU with real time Clock and Display capabilities.
The requirements are
1) 3 Pumps working per 2 in circular rotation (1-2) , (2-3), (3-1) for scheduled time during the day
2) 1 Filter Pump which running schedule
3) 1 waste water Pump which run with a level sensor command
4) 1 electrovalve which open with a filling level sensor
5) 1 low level sensor protecting the 4 pumps for dry working
6) 1 Voltage detector
Schedule program for the 3 pumps with 1 zelio button is:
1st program : (08:00 – 14:00) and (17:00 - 24:00)
2nd program : (07:00 – 15:00) and (17:00 – 01:00)
3rd program : (07:00 – 16:000 and (17:00 – 01:00)
4th program : (07:00 – 01:00)
Schedule for 4th filter pump is 2 hours stop/ 1 hour run per day

OUTPUTS
O1 RUN Pump No1
O2 RUN Pump No2
O3 RUN Pump No3
O4 RUN Filter Pump
O5 RUN Waste water Pump
O6 Filling Valve command OPEN
O7 Alarm Horn
Note: The program needs a latch at the Z1 cam encoder in order to restart after a power failure. It is left upon the user to decide if this requirement will be added . In this application the customer have chosen NOT to have that capability. A manual restart needed . Alarm with horn when power voltage fail
