Range shall be 0-138.6” and display shall be with ½” high back lit LCD digits. Controller shall be adjustable for pump and alarm set and reset points using only a screwdriver. Level and ON and OFF set points require only turning a 5 position selector knob. No punch and scroll techniques shall be required to check or adjust set points. Controller shall have plug in type terminals for all input and output connections to allow simple should replacement be required. Display shall flash during a high level condition. A plug in type auxiliary relay shall be provided for operation of the motor starter contactor to maximize life of controller pump contacts.

  1. Interior door operator controls and indicators shall include RUN lights, OVERLOAD lights, and High Level lights for each pump. A PHASE LOSS/VOLTAGE FAULT light shall be provided. Lights shall be 30mm transformer type with 6.3V lamps. The H-O-A switches and overload reset push button shall be 30mm. Electro-mechanical elapsed run time meters accurate to 1/10th hour shall be provided for each pump. Interior door shall allow access to all breaker resets at surface level.

  1. The unit shall include a primary power surge protection device, control circuit surge suppressor (plug- in module with indicator light), and instrument signal surge suppressors. The level circuits shall be intrinsically safe using dual fused barrier. A plug-in type indicating voltage/phase monitor shall be provided to protect against phase or voltage fault conditions.

  1. A condensate heater with adjustable thermostat shall be provided.

  1. Terminal strip shall be provided for connection of level sensor and flow meter (if applicable) which shall be mounted for easy access. All components shall be labeled and all wires shall be numbered. Schematic drawing shall include wire and terminal numbers for each component.

  1. A transformer shall be provided where required or specified with a rating of 750VA. Transformer shall be properly fused and control circuit shall be equipped with a control circuit breaker.

  1. Overload resets shall be provided. Resets shall be a through-the-door push button with spring return.

  1. OPTION: A top mounted RED alarm light for High Level and Overload conditions shall be provided in addition to the flashing level indicator display high level feature. Alarm light shall be [LED Flashing] [Lexan lens with 40 watt bulb with flasher] [Strobe].

  1. OPTION: A DIGITAL FLOW METER with LCD display and simultaneous display of flow rate and gallons total (to 99999999) shall be installed for each pump. Unit shall be potted into an aluminum frame housing and mounted in the interior door of the enclosure. Unit shall be a pulse input type operating a 24vdc power supply. Total shall be re-settable and may be locked for non-reset operation. A power supply rated for 24vdc 250mA minimum output shall be provided. An LED on the power supply shall provide operation indication.

  1. OPTION: A motor monitoring device which shall detect a dry run/“dead head”(undercurrent) condition shall be installed for each motor. In addition, the device shall be capable of providing redundant motor protection for overload, high and low voltage, short cycle, and undercurrent. Three phase units shall also provide phase and amperage unbalance detection. Unit shall provide a digital code of any fault or status and be selectable for display of voltage or amperage for each leg and average. Display shall provide amperage or voltage. All units shall be fully programmable for actual amperage/voltage selection using the digital display and shall be capable of programming delay periods and number of restarts after a detected fault condition. Units shall be back-plate mounted with an interior door cut out to allow viewing and adjustment without opening panel interior door.

  1. OPTION: A REMOTE LOCK OUT circuit with indicating light shall be provided. Circuit shall include a 24vdc relay and [LOCK OUT] [TANK FULL] indicating light. Primary lock out panels shall additionally be equipped with a 24vdc power supply suitable for application.


  1. Each pump shall be equipped with a submersible pressure transducer of stainless steel construction compatible with control panel and with a static accurate of no more than 1% of range shall be provided. Range shall be 0-5 PSI and the unit shall provide a 4-20mA signal and be equipped with an integral surge suppressor.

  1. Submersible transducers shall be supplied with a shielded cable suitable for the application and of continuous length with a heavy outer jacket. A strain relief/riser exit fitting shall be provided. Cable shall be equal to pump power cable length. Range shall be as required for application and compatible with level display.

  1. Transducers shall be equipped with a desiccant type disposable drier tube for shipment and a permanent bellow breather located in the control panel for operation.

  1. OPTION: A flow meter sensor shall be provided for each pump. Device shall be a paddle wheel type of PVC construction with jewel bearings to resist wear and clogging. A 15’ cable shall be provided for each.
