  • Page 3: Introduction

    INTRODUCTION: The Sigma Myriad DPC (Duplex Pump Controller) is a state of the art microprocessor based, user configurable instrument for the monitoring and control of two (2) constant speed or (2) variable speed driven pumps. The Myriad DPC performs all of the functions found in a full size control panel.

  • Page 16  Allows the MODBUS comm port to be set to match network requirements. Exit to save, then cycle Power to adopt new node.  High and low level alarms are available on Relay 3. If desired this selection will provide high level alarm on RLY #3 and low level alarm on digital output #4.
  • Page 17 Select 'REVERSE' to drive the output down when the process value exceeds the setpoint, as in pressure boosting applications. Select 'FORWARD' to drive the output up when the process value exceeds the setpoint. Select 'DUPLEX' for two pump operation Select 'SIMPLEX' when pump 2 is not installed. The Auxiliary PCB is a factory installed option.
  • Page 18 When float control is enabled it serves as a backup control to the analog level sensing. This setting controls at what point the floats assume control. Select LEAD FLOAT to initiate backup control when the float above the low float is tipped. Used when the top 3 floats are hanging above the normal pumping range.
  • Page 19 Following the procedure above, select a level value at which the lead pump turns off. Use ‘NEXT’ with the 'ENTER' button to access the: LAG PUMP ON SCREEN Select a value which turns on the lag pump. Use ‘NEXT’ and ‘ENTER’ to access the: LAG PUMP OFF SCREEN Again, select a level value which turns off the lag pump.
  • Page 20 Change pump off delay as described above and select ‘NEXT’ and press ‘ENTER’ to advance to the: LEVEL ALARM SCREENS The next screens are as follows: Low Level Alarm Set Point Low Level Alarm Reset Point High Level Alarm Set Point High Level Alarm Reset Point Alarm Timer (This function controls the timing for alarms to be detected) Adjust and advance through the alarm settings as described previously.

    APPENDIX ‘B’ DPC ADDENDUM VERSION 1.9 The intention of this addendum is to point out the differences between the Myriad DPC Manual (written for DPC V1.8) and the V1.9 upgrades. 1. The Real-time clock can be stopped if static or surges occur. Now it has an automatic reset so that if it stops it will restart in 60 seconds.
  • Page 29 APPENDIX ‘C’ AUXILIARY PCB ADDENDUM VERSION 4.0 The auxiliary PCB option adds standardized inputs and outputs to the DPC controller. These are some of the most commonly requested custom programming functions. This PCB is hard soldered at the factory. It is not user serviceable. Its existence is indicated by a 10 pin terminal on the back of the controller.
  • Page 30 Float Control; Terminal #4 is for a normally open ’low‘ or ‘off’ float. It can be used to unlatch the lead and lag pumps or as a low water cutoff to redundantly protect a pump from running dry. Terminal #5 is for a normally open lead float. Terminal #6 is for a normally open lag float.
