Event memory
The following events can be saved in the event memory
with date and time:
- Deletion of the event memory,
- Relay outputs 1A, 1B, 1C on/off,
- Relay outputs 2A, 2B, 2C on/off,
- Auxiliary input on/off,
- Breakdown and return of the auxiliary voltage,
- Breakdown and return of the measurement
voltage,
- Reset of real power EMAX,
- Synchronization of the internal clock,
- Tariff change over 1/2.
The event memory can be read out with PC and the
programming and reading out software
PSWbasic
.
A breakdown of the measurement voltage is recognized,
if:
- the measurement voltage is smaller than 50% of the set
primary voltage of the voltage transformer
- and the breakdown lasts longer but 500ms without
interruption.
In the device a memory is available, which is divided
into the ring buffer and the event memory. The dimension
of the event memory can be programmed to determine
the number of events, that can be saved in the memory. If
the number is set to "0", the whole memory is available
for the ring buffer.
If the number of events is changed, the contents of the
event memory and ring buffer are deleted.
The dimension of the memory for event memory and
ring buffer is depending on the RAM of the UMG 503.
