Mains Power Line Current negative values mean energy is being sent to the grid

Drum Status Enumerations

• other(1): an error not defined by the other enumerated values.
• noError(2): the drum is working properly.
• interlockError(3): the drum has failed to lock into a correct display position. It is hung up between two adjacent drum faces.
• stuckError(4): the drum cannot be moved from its present position, due to a problem with the drum mechanism.
• positionError(5): the drum has moved to a position other than the position requested by the DMS controller.
• positionUnknownError(6): the DMS controller cannot determine the position of the drum.

Lamp Status Enumerations

• other(1): an error not defined by the other enumerated values.
• noError(2): the lamp is working properly.
• stuckOff(3): the lamp is not able to turn on.
• stuckOn(4): the lamp is not able to turn off.

Power Supply Enumerations

• other(1): an error not defined by the other enumerated values.
• noError(2): the power supply is working properly.
• inputPowerError(3): the power supply is not receiving an acceptable power input.
• powerSupplyFailure(4): the power supply is indicating a failure (e.g., not responding as it should, receiving acceptable input but unable to provide acceptable output)
