What to do if my Leeson Inverter shows 'PWR SAG'?
If the Leeson Inverter displays 'PWR SAG' due to an erratic AC line, perform a factory reset using Parameter 65-PROGRAM. This action updates the software and allows the fault to be reset.
Why is my Leeson SPEEDMASTER MICRO display blank and the drive won't run?
If the Leeson Inverter displays a blank screen and will not run, it indicates the power supply has shut down. Inspect the heatsink fans for obstructions. If the fans are clear and the issue persists, contact the AC Tech Service Department.
Why does my Leeson SPEEDMASTER MICRO show an OVERLOAD error?
The Leeson Inverter might be showing an OVERLOAD error because the drive is undersized for the application, or there might be a problem with the motor or the driven equipment.
Why does my Leeson Inverter show 'HI VOLTS'?
If the Leeson Inverter displays a 'HI VOLTS' error, it could be due to high line voltage, an overhauling load, or the deceleration rate being set too fast.
What causes 'HI TEMP' error on Leeson Inverter?
If the Leeson Inverter displays a 'HI TEMP' error, it could be due to a high ambient temperature or a fan failure (if equipped).
What to do if Leeson Inverter shows 'CONTROL'?
If the Leeson Inverter displays 'CONTROL', perform a factory reset using Parameter 65-PROGRAM. This action updates the software and allows the fault to be reset.
Why does my Leeson SPEEDMASTER MICRO display 'LO VOLTS'?
If the Leeson Inverter displays 'LO VOLTS', it is due to low line voltage.
What causes 'OUTPUT' error on Leeson SPEEDMASTER MICRO Inverter?
The 'OUTPUT' error on a Leeson Inverter can be caused by a phase to ground short, a phase to phase short, the FX or AC BOOST being set too high, or a bad transistor module (IPM).
