Machine won't spin

1 comments:
Mr. Anderson
February 3, 2025

The Milnor E-P Express machine may not spin due to the following reasons identified in the context:

1. Inverter Fault: If the microprocessor does not receive an input from the inverter within 14 seconds of starting a formula, the basket remains stationary.

2. Vibration Switch Activated: If the vibration switch closes, the machine stops the spinning operation and initiates a recovery sequence.

3. Power Application Delay: When power is first applied to the machine, at least 80 seconds must elapse before further operations can be attempted to allow the basket to stop completely if it was in high-speed extract mode during a power loss.

To resolve these issues, follow the recovery steps specified in the manual, such as pressing the appropriate recovery keys, ensuring proper input signals, or waiting for the required time.
