Power Analyzer UMG 505

Event memory

The following events can be stored in the event memory with time and date:

• Deletion of the event memory
• Changes to the digital input
• Failure and return of the auxiliary voltage
• Changing of the digital Emax outputsFailure and return of the measurement voltage

Up to a maximum of 9999 events can be stored. The data can only be read out with the PC and the PSW professional software.

Measurement value displays and automatic display rotation

The extremely legible LCD display in connection with the function keys informs the user about the selected measurement values (current, low, high and average values). With the UMG 505, three measurement values can be simultaneously displayed in the LCD data field and up to 140 data fields can be individually designed with the PSW basic software. A cycle between 1 and 9999 seconds can be set for measurement value rotation and a selection of measurement values can be made.

Weekly time switch

The time switch in the UMG 505 has 100 time channels. Each time switch channel specifies a period of time. The period of time is specified by the start-up point and the switch off point. The start and stop points are defined by weekdays, hour and minutes.

Each time switch channel can simultaneously control a time switch output and select a consumption meter. A time switch output can be allocated to a “digital output” when programming the digital outputs.

Limit value monitoring

Five limit value outputs can be programmed to monitor the measurement values. Each limit value output can be allocated to up to 3 comparators (A, B, C). The following can be programmed for each comparator:

• 2 limit values and 2 measurement values or
• 2 limit values and 1 measurement value or
• 1 limit value and the minimum start-up time

Any limit value violations established by a limit value output is registered in the event memory with a record of the time and can also be issued on a “digital output”
