- Lock Rotor Current: Activates when a lock rotor condition has been detected on the normal power. Note that the
motor will not be permitted to start on the normal power as long as this alarm has not been reset from the alarms
page.
- Fail to start: Activates if there is and under-current draw of two phases when the motor should be running. A 20
seconds factory set delay is used to give the motor enough time to start before signalling this alarm.
- Undercurrent: Activates when current is under 30% of FLA and motor has been running for 15 seconds.
- Overcurrent: Activates when current is above 120% of FLA.
- Under voltage: Activates when normal power voltage is below 80% of nominal voltage.
- Over voltage: Activates when normal power voltage is above 120% of nominal voltage.
- Phase Unbalanced: Activates when there is a difference of more than 30% of nominal voltage between the normal
power voltage readings.
- Ground Fault: Activates when the ground fault input current is above the factory set value after a factory set delay.
- PT Fault Detected: If an optional dual pressure sensor is installed, it will be activated if the two pressure
transducers show different readings. Further investigation is advised to determine what caused the different
readings. Note that the controller will always choose the lowest pressure reading to determine the actual system
pressure.
- Overpressure: Activates if the analog readout of the discharge pressure goes higher than the overpressure set
point in the discharge pressure sensor page.
-
Underpressure: Activates if the analog readout of the discharge pressure goes lower than the “Under Pressure”
set point in the discharge pressure sensor page.
-
Water Reservoir Low: Activates if the “Water Reservoir Low” contact input is triggered or if the analog readout of
the water reservoir is enabled and is lower than the water reservoir low set point in the “Water Level” sensor page.
- Water Reservoir
Empty: Activates if an external contact triggers the optional “Water Reservoir Empty” input.
-
High Water Level: Activates if the optional “High Water Level” contact input is triggered or if the analog readout of
the water level is enabled and goes highe
r than the “High Water Level” set point in the “Water Level” sensor page.
-
Main Relief Valve Open: Activates if an external contact triggers the optional “Main Relief Valve Open” input.
- Io_expX-inX alarm: Activates if the specific expansion programmable input on the specific expansion board is
activated and triggered.
- High Motor Temperature: Activates when the optional high motor temperature contact is activated.
- High Motor Vibration: Activates when the optional high motor vibration contact is activated.
- Control Voltage Not Healthy: Activates when the 24VAC power input to the IO cards is below the acceptable
functional range.
- Motor Trouble: Activates when a motor related alarm condition is present (overcurrent, undercurrent, fail to start or
ground fault).
- Pump Room Alarm: Activates when a pump room related alarm condition is present (overvoltage, undervoltage,
phase unbalanced).
- Flow Meter On: Activates when the optional flow meter input is activated.
