Averages are taken over the sample period and the average recorded with time stamp. (b) The last 128 sequential pump station events with time of occurrence. Events shall include but not be limited to: all alarms, starting of individual pumps, stopping of individual pumps and changing of selector switches. (c) Station flow and pressure are shown every second for the previous 60 seconds and every minute for the previous 30 minutes. If a shutdown occurs, the flow and pressure tables are locked in so that the operator may view how the pump station was performing immediately before the shutdown occurred. (2) Status. Will display the current operating status. When the station is running, the display will show the setpoint pressure, actual pressure, flow, and pump rpm. (3) Alarm Info. It will display detailed information on the alarm, time of occurrence, pumps operating at time of alarm and how to correct the alarm condition. (4) Daily Log. It will display the following: Last time of log reset, individual pump run times, run times since last reset, pump starts, pump starts since last reset, total flow, total flow since last reset, highest flow rate with time of occurrence, alarm conditions, and times since last reset. (5) Scroll Key. Used to scroll up and down through data. 8. Operation: a. During non -irrigation times, the pressure maintenance pump (PM) will cycle on and off as required to maintain irrigation system pressure. The cycling pressures can be user selected and can be set substantially below normal set point pressure, if desired. If the PM pump cannot maintain the desired pressure, then the VFD will start the first pump and will gradually ramp the pressure up to desired irrigation pressure. b. The pump speed will be modulated to hold a constant discharge pressure regardless of flow. As the flow rate increases and the VFD pump can no longer maintain pressure while at maximum speed, the next sequential pump will be started and the VFD driven pump will accordingly reduce its speed and modulate. C. An algorithm shall be include for accurately reducing the VFD pump speed as the next sequential pump is started so that no pressure surges are generated during the transition (even with across the line starting). If the user prefers to switch the VFD from pump to pump for sequential starting, he can select this option with the OID. d. As the flow continues to increase, pumps will sequentially be started until all pumps are operating. As the flow begins to decrease, pumps will be sequentially turned off until only a single VFD driven pump is operating. When a no flow condition occurs, the VFD pump shall be turned off. E. Skid Wiring: All wiring from control panels to motors shall be in liquid -tight conduit with copper conductors rated not less than 600 volts AC and of proper size to carry the full load amperage of the motors without exceeding 70% capacity of the conductor.

The resetting shall be automatic after full power is restored for 5.0 seconds, with pumps sequentially restarting. The phase failure - low Voltage indicator light is to remain illuminated until manually reset. 4. Low System Pressure Safety Shutdown: Low discharge pressure is to be sensed by the pump starting set point. When the station discharge pressure decreases to this point and maintains a start signal for a preset time, the pumps will be de -energized and remains so until the circuit is manually reset. An indicator light shall illuminate to indicate a low discharge pressure shutdown has occurred. 5.
