2. Pride in Workmanship Worldwide MASTER Fire Pump Controllers Are Engineered to the Highest Standards in the Industry 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

3. Pride in Workmanship Worldwide Features That Make MC Series Fire Pump Controllers a Smart Choice 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

4. Pride in Workmanship Worldwide MC Features Continued Restart Time Delay 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. Pride in Workmanship Worldwide MC Features Continued Control Chassis Control chassis has Diagnostic LEDs, latched connectors and a steel card cage for mechanical protection of printed circuit boards

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

7. Pride in Workmanship Worldwide MC Features Continued 35% Voltage Drop Model MCP 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.

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

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

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

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

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

15. Pride in Workmanship Worldwide MC Features Continued DC Shunt Trip 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. Pride in Workmanship Worldwide Motor Starting Types Across-the-line Part-winding Primary reactor Wye-delta (open) Wye-delta (closed) Soft Start Autotransormer

17. Pride in Workmanship Worldwide Motor Starting Types Continued 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

18. Pride in Workmanship Worldwide Motor Starting Types Continued Fire Pump Starting Type Characteristics

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

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