4.9. Status Messages

The MagnaLOAD electronic load has various messages, which elaborate on the product’s present status. A message may indicate normal operation, power limiting as a result of the MagnaLOAD electronic load’s operating profile, or steps to resolve a fault.

Messages for Status: Enabled

  • Input enabled.

  • Product is operating below its minimum voltage rating. Increase the input voltage to proceed.

  • Exceeded MOSFET power rating.

Messages for Status: Disabled

  • Input disabled.

Messages for Status: Soft Fault

  • Voltage exceeded the trip point. Press CLEAR to resume.

  • Voltage has fallen below the trip point. Press CLEAR to resume.

  • Current exceeded the trip point. Press CLEAR to resume.

  • Power exceeded the trip point. Press CLEAR to resume.

  • Remote sense loss. Only 10 percent compensation is allowed. Press CLEAR to resume.

  • Global shutdown occurred.

Messages for Status: Hard Fault

  • Global shutdown occurred.

  • Chopper stage currents have exceeded product rating. Verify load does not exceed product ratings.

  • Excessive communication errors detected. Check cabling and addressing resistors. Call technical support.

  • Product has exceeded its voltage rating. Investigate the cause before retrying.

  • Product has exceeded its current rating. Investigate the cause before retrying.

  • The internal power supply has blown a fuse. Contact Magna-Power for support.

  • Analog or Digital input voltage exceeded the max voltage specified. Investigate the cause before trying again.

  • One of the AC Input Phase is missing. Investigate the cause before retrying.

  • One or more fan has stopped spinning. Investigate the cause before retrying.

  • Linear modules have exceeded their temperature rating. Check for ventilation blockages and the ambient temperature.
