  1. The panel shall be equipped with a properly sized main disconnect circuit breaker (thermal magnetic permanent trip Square D type HDL) with inner door interlocked operator handle. Additional breakers shall include Motor Breakers (Square D type HDL), Control Circuit Breaker (Square D QOU), and Accessories Circuit Breakers (Square D type QOU) where applicable. All breakers shall be selected for the required trip characteristics of the components protected and shall be back-plate mounted. Fuses for voltage/phase monitor shall be provided.

  1. The motor starters shall be a heavy duty NEMA rated Square D 8536 with properly selected thermal overloads with alarm auxiliary contacts for overload condition.

  1. Interior door operator controls and indicators shall include RUN lights, and OVERLOAD light. A PHASE LOSS/VOLTAGE FAULT light shall be provided. Lights shall be 30mm transformer type with 6.3V lamps. 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. An indicating controller with digital level read out to 1/10th of an inch shall be installed. Range shall be 0-138.6” and display shall be with ½” high back lit LCD digits. The 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.

  2. A level signal simulator shall be provided to test the float level circuit. A push button will simulate the level cycle for testing.

  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 sensors 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.

  2. A plug-in type alternating relay shall be provided. Relay shall provide automatic lead/lag alternation between two pumps and be equiped with a push-to-test button.
  1. OPTION: A top mounted RED alarm light for High Level 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. Unit shall be potted into a 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 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 also shall 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.

  2. OPTION: The top alarm light will be energized should a pump overload condition occur.

  3. OPTION: Enclosure shall include a 17” X 11” outer door viewing window which allows view of indicators.

 

1.02 INSTRUMENTATION
