Restart, unit restart
Resets all parameters to factory settings. The storage area for measured
values is cleared on restart. (see also „cold start" and „warm start")
Rolling registration period
Operational mode in which the registration periods overlap each other. Ex-
ample: the average maximum demand value of the last 15 minutes is calcu-
lated every 5 minutes. This is meaningful for more accurate maximum
demand calculations.
RS232
Interface definition according to EIA (USA-Standard), corresponds to V.24.
Scroll display / Scroll list
Operational mode of the display, where either automatically or triggered by
the ANZ control input a predetermined list of parameters and measured
values is scrolled over the display.
Spontaneous event buffer
Storage area for „unusual" events. (e.g. alarms, parameter changes). This
is organized as a circular buffer.
Standard display
This is shown on the LC display when no keys are pressed. It shows
amongst other things date, time, active rate and registration period length.
Synchronization
Adjusts the device time synchronously to an external time standard. Syn-
chronization only affects the seconds. If the second value is smaller than
30, it will be reset to zero, if not the minute value will be incremented in ad-
dition. Synchronization can be done using the SYN control input or via
command from the remote metering central.
Synchronization window
Limits synchronization of the unit to a time window surrounding the end of a
registration period. Any attempt to synchronize the unit outside of this win-
dow results in an alarm.
Totalling unit, summation unit
Adds up (totals) the energy amounts of a number of pulse or counter in-
puts, then calculates the average demand value over the registration pe-
riod.
V.24
Interface definition according to CCITT (European standard).
Warm start
A warm start is performed after a short period of power failure (less than 7
days). All data stored in the unit will be retained. The internal real time clock
is not affected.
