  • Page 11 PUMP CALL SEQUENCE - Setup Parameters Pump Stop Mode - Parameter P.17 This Parameter establishes which pump is the next one to be stopped, when there are two or more pumps on. The Controller has a corresponding “Pump Off Level” setting for each of the “Pump On Level” settings. For the “Pump Stop Mode”...
  • Page 12 ALTERNATION SEQUENCE MODE STANDARD ALTERNATION Parameter P.16 = 1 Notes: 1. Unless there is some special circumstance that requires a more complicated Movement of Lead Pump Upon Alternation pump call sequence, this is the sequence that should be used. 2. Parameter P.17 must be used to select either First On Last Off or First On First Off.
  • Page 13 ALTERNATION SEQUENCE MODE PUMP 1 ALWAYS LEAD Turns Off With Other Pumps On Parameter P.16 = 3 Notes: 1. This sequence is used when it is required that pump 1 always be lead, and when it must be turned off when another pump(s) comes on. When a pump Movement of Lead Pump Upon Alternation from the second group is required, pump 1 is first turned off, then after the Lag Pump Delay, the other pump is turned on.
  • Page 14 ALTERNATION SEQUENCE MODE FIXED ALTERNATION Parameter P.16 = 5 Notes: 1. This sequence is used when no alternation is required and when pump 1 should normally be lead pump. Other pumps may be made lead by setting Parameter P.39. 2. Discrete Inputs programmed as Pump 1-4 Disable inputs may be used to disable pumps.
  • Page 15 DISCRETE INPUT FUNCTIONS The following is a description of the Functions that may be assigned to the Discrete Inputs using Parameters F.01 - F.18: Notes: 1. All Discrete Inputs are originally programmed with default Functions, but they may be changed at any time using Parameters F.01 - F.18.
  • Page 16 DISCRETE INPUT FUNCTIONS Call Pump 1 (2, 3, 4) Last - Functions When a Discrete Input programmed for “Call Pump 1 (2, 3, 4) Last” is closed, it assigns the respective pump to standby status, where it will always be called to run last. If more than one but not all of the pumps are assigned to standby status, they will all be available to run if needed, but in a fixed order, and always after the pumps not assigned standby status.
  • Page 17 DISCRETE INPUT FUNCTIONS Float Backup - Off Level - Function 33 When a Discrete Input programmed for “Float Backup - Off Level“ closes, the Float Backup logic will be armed and made ready to latch in one pump call for each of the “Float Backup - 1st , 2nd, 3rd, 4th On Level“ inputs that close.

  • Page 23: Flush Cycle

    FLUSH CYCLE The Flush Cycle feature is provided to periodically maximize the lift station’s discharge flow rate, to flush the sludge build up from the bottom of the wet well and from the discharge pipe. Flush Cycle Steps: 1. The “LEVEL” indicator begins to flash to indicate that the Flush Cycle has started. 2.
  • Page 24 FLOW CALCULATOR Latest Inflow Rate - The Most Recently Determined Flow Rate into the Lift Station The Flow Calculator determines the “Latest Inflow Rate” of liquid flowing into the lift station by observing how long it takes for the wet well level to rise a “known distance”, while all pumps are off. Knowing the sur- face area of the wet well (Parameter P.46), the volume of liquid per minute flowing into the wet well is calcu- lated.

  • Page 26 COMMUNICATION WITH A SCADA SYSTEM A SCADA system may communicate with the controller through either the RS232 Serial Port or through the Optional Ethernet Port. The controller operates as a MODBUS slave, where all communication is initiated by the MODBUS master. MODBUS Functions Supported Function Code...

  • Page 27: Rs232 Serial Port

    RS232 SERIAL PORT The RS232 serial port allows a SCADA system to communicate with the Controller using the Modbus RTU protocol. Setup of RS232 Serial Port The controller’s RS232 serial port must be setup to communicate with the device it is connected to. The Baud Rate, Parity Mode and Stop Bits Parameter values of the two devices must be set to match.

  • Page 32 SCADA FEATURES Level Level Monitoring The Level may be monitored by reading SCADA Register 40011. The value will be just what is displayed on the front of the controller but with no decimal point. If an operator has the Controller in the Level Simulation Mode, Register 40011 will show the simulated level.
  • Page 33 SCADA FEATURES Forcing a Pump On To Force a Pump On set Coil 17, 18, 19, or 20 in Register 40002. To return the pump to normal operation, clear the respective Coil. Upon a loss of serial communication, the Force Pump On Logic will be automatically reset, and any pump that had been remotely forced on will be turned off after the delay set on Parameter P.38.
  • Page 34 SCADA FEATURES High Level Telemetry The High Level Alarm is generated from a comparison of the displayed Level with the High Level alarm setting. This alarm works when Parameter F.19 is set on either 1, 2 or 3. The status of this alarm may be read from Coil 129 in Reg- ister 40009.
  • Page 35 SCADA TROUBLESHOOTING Communication Activity Indicator The Communication Activity Indicator (Parameter d.07) may be used to help troubleshoot communication issues. It typically pulses from “0” to “1” momentarily to indicate that the master is sending a message. It may stay “1” if there is very little time between messages.
