5.15. Statuses

The Accessory has various statuses corresponding to its present state of operation. These statuses can be viewed on the front panel, programmatically by computer command, or using the 25-pin user I/O connector. The available statuses are as follows:

Enabled

The Accessory’s input is engaged and processing power.

Disabled

The Accessory’s input is disengaged and all systems are normal. The Accessory is awaiting a START command to engage its input. When in a Disabled state, there is an electrical disconnect between the product’s dissipative elements and the DC input terminals through a high speed switching device.

Soft Fault

The Accessory’s input is disengaged as a result of a soft fault that occurred. A soft fault occurs when an user-programmed limit is reached, such as a trip setting. A description of the soft fault is displayed on the message line. A soft fault can be cleared with the CLEAR function, placing the Accessory into a Disabled status. When in a Soft Fault state, there is an electrical disconnect between the product’s dissipative elements and the DC input terminals through a high speed switching device.

Hard Fault

The Accessory’s input is disengaged as a result of a hard fault that occurred. A hard fault is a system shutdown resulting from an operating condition that has the potential to damage the product, for example, exceeding the products specifications. A description of the hard fault is displayed on the message line. A hard fault fault can only be cleared by power cycling the product. When in a Hard Fault state, there is an electrical disconnect between the product’s dissipative elements and the DC input terminals through a high speed switching device.

Caution

Ignoring hard faults and repeatedly operating the Accessory in a manner that triggers a hard fault will eventually result in product damage.
