What Does The 777-P2 Have That The 777 Does Not?

• Battery programming - program the unit without applying line voltage by using a 9 volt battery to power the unit
• A new 16 bit memory map to aid developers using PLCs, software, and other SCADA equipment (in addition to the legacy 8 bit memory map)
• Compatible with SymCom communications modules and Littelfuse remote monitors, including:

• RM-1000 o RM-2000
• Solutions Software
• CIO-ON-P
• CI0-777-PR
• CIO-EN
• CIO-MB
• RS485MS-2W

• Communications settings can be programmed on the face of the unit (and via network communications)
• Current unbalance, voltage unbalance, and ground fault current are viewable on the display
• Custom Modbus register assembly - group together only the parameters you want to read
• Adjustable linear overcurrent trip delay time that can be programmed on the face of the unit (and via network communications)
• Many network accessible features (requires Solutions software or some other SCAOA type software to read/program these):

• 10 fault memory
• Programmable low power and high power trip points
• Aojustabte current unbalance and ground fault tnp delay curves o Ability to set many timers/delays m either minutes or seconds
• Motor acceleration options to allow high horsepower motors to come up to speed
• Ability lo enable/disable reverse-phase monrtonng
• Pre-trip warmng alarms
• Line frequency measurements
• Enable or disable high voltage, low voltage, voltage unbalance, reverse phase, and single-phase trip conditions
• Programmable ground fault current scale

• Expanded ranges for:

• Current Unbalance
• Voltage Unbalance
• Undercurrent Tnp Delay
• Thermal Tnp Class
• Rapid Cycle Time Delay
• Much more
