Electric Fire Pump Controllers
FD70 Reduced Voltage –
Wye-Delta Open Transition
FD70
Standard Features
The FD70, type LMR Controller uses a method of • Microprocessor Control
connecting the pump motor windings into wye • Pressure, Voltage & Current Display
configuration to start, then switching to a delta • Alarm & Status LED Indication
configuration to run. This reduces the starting current • LCD Message Retrieval -
of the motor significantly. Wye-Delta starting is Last 1024 Messages
the only method that has a starting torque efficiency • Pressure Transducer - 600 PSI Max.
of 100%. The FD70 can be programmed for either • Printer-Recorder
fully automatic or semi-automatic operation. • Elapsed Time Meter
• Number of Operations Counter
• Run Period Timer
• Sequential Start Timer
• Weekly Test Timer
• Common Alarm Relay & Contacts
• NEMA 2 Enclosure
• NEMA Rated Contactors
• Emergency Start Operator
