3 with Automatic Transfer Switch Ambient Temperature Rating Operating Modes Surge Suppression Disconnecting Means Service Entrance Rating Standard: 5 C to 40 C / 41 F to 104 F The controller shall have the capability of running the pump motor in the following three (3) modes via a speed mode selector switch: Variable mode: Upon an automatic or manual start, the controller shall start the pump through the variable frequency drive (VFD) and instantly regulate the motor speed in reference to the discharge pressure Preset mode: Upon an automatic or manual start, the controller shall start the pump through the variable frequency drive (VFD) and run the pump motor at a pre-determined speed. This pre-determined speed shall be adjustable on the variable frequency drive (VFD) itself Bypass mode: Upon an automatic or manual start, the controller shall start the pump through the reduced voltage soft start bypass circuit. Surge arrestor rated to suppress surges above line voltage Isolating switch and circuit breaker assembly: - Door interlocked in the ON position - Isolating switch rated not less than 115% of motor full load current - Circuit breaker continuous rating not less than 115% of motor full load current - Overcurrent sensing non-thermal type, magnetic only - Instantaneous trip setting of not more than 20 times the motor full load current Common flange mounted operating handle Suitable as service entrance equipment Emergency Start Handle Flange mounted Pull and latch activation Integrated limit switch Across the line start (direct on line) Locked Rotor Protector Operate shunt trip to open circuit breaker Factory set at 600% of motor full load current Trip between 8 and 20 seconds Electrical Readings Pressure Readings Pressure and Event recorder Pressure Sensing Voltage phase to phase (normal power) Amperage of each phase when motor is running Continuous system pressure display Cut-in and Cut-out pressure settings Pressure readings with date stamp Event recording with date stamp The recorder will register and keep in memory pressure fluctuations over time that have occurred over the previous seven (7) days and events, alarms, general system information that have occurred over the previous fifteen (15) Information is retrievable through DB9 communication port accessible without having to open the controller door.
