  1. Pride in Workmanship Worldwide

  2. Instant-On circuitry Restart time delay Modular Mother board All printed circuits are enclosed in a steel card cage Diagnostic Plug and LEDs Triple redundant control transformers 35% voltage drop MASTER Fire Pump Controllers Are Engineered to the Highest Standards in the Industry

  3. No field Programming LED’s and SPDT contacts for visual and remote monitoring of alarms Vertically mounted ISO SW and CB Digital display readout Single phase protection Independent pressure and alarm recorder DC Shunt trip Features That Make MC Series Fire Pump Controllers a Smart Choice

  4. Restart Time Delay MC Features Continued Controllers utilize a re-start timer to delay the instantaneous re-start of the controller. This allows electromagnetic fields in the motor to decay.

  5. Control Chassis MC Features Continued Control chassis has Diagnostic LEDs, latched connectors and a steel card cage for mechanical protection of printed circuit boards

  6. Triple Redundant Control Transformers MC Features Continued Triple Redundant control transformers privide full control power even if a phase is lost

  7. 35% Voltage Drop MC Features Continued Controllers will continue to operate if the voltage drops by as much as 35% of rated voltage. This can be critical when starting the fire pump on emergency power. Model MCP

  8. Isolation Switch and Circuit Breaker MC Features Continued Vertically mounted Isolation Switch and Circuit Breaker with Separate operating handles and interlock.

  9. Door Display MC Features Continued Through the door digital display reads out voltages, phase currents and pressure

  10. DR2500 Paperless Pressure and Alarm Recorder MC Features Continued Independent digital recorder saves the latest 2500 pressure points and 350 alarm points into a separate permanent memory buffers

  11. DR2500 Paperless Pressure and Alarm Recorder MC Features Continued The DR2500 is specifically designed to communicate through an RS-232 serial port directly to a lap‑top computer or a network server

  12. DR2500 Paperless Pressure and Alarm Recorder MC Features Continued Data may be downloaded by using any terminal emulator program such as Terminal, Hyperterm, etc.

  13. DR2500 Paperless Pressure and Alarm Recorder MC Features Continued DR2500 control menu

  14. DR2500 Paperless Pressure and Alarm Recorder MC Features Continued Retrieved data

  15. DC Shunt Trip MC Features Continued Controllers use a DC shunt trip coil powered from all 3 phases. The locked rotor protector will still operate under a single phase condition.

  16. Across-the-line Part-winding Primary reactor Wye-delta (open) Wye-delta (closed) Soft Start Autotransormer Motor Starting Types

  17. Reactor Comparison Reactor uses a standard electric motor Reduces complexity of field wiring - wired same as across the line Low Power Factor makes the reactor ideal for gen-set applications Motor Starting Types Continued

  18. Fire Pump Starting Type Characteristics Motor Starting Types Continued

  19. Leading Phase Monitor™ Used on Wye-Delta (open) controllers Reduces open circuit transient to closed circuit levels Allows you to use Wye-Delta (open) as an option to Wye-Delta (closed) Motor Starting Types Continued

  20. Leading Phase Monitor™ Motor Starting Types Continued Wye-Delta Transition Transients (typical) Closing the Delta contactor (run) with closing voltage leading the Wye contactor (start) gives you closing currents about the same as closed transition controllers
