Additional Information About The Load Profile Data; Tariffs - Siemens SENTRON PAC4200 Manual

Description

2.5 Tariffs

Impact of a measuring voltage failure
A failure of the measuring voltage has no effect on the load profile.
Impact of a supply voltage failure
The device records shorter periods when the supply voltage fails and when it is restored.
It does not record any substitute values for the duration of the power failure.

Additional information about the load profile data

SENTRON PAC4200 records the following additional information for each period:
● "Resynchronized"
The period was prematurely ended by the device due to a synchronization irregularity.
This identifier is set as long as the time is undefined. The time can be undefined if the
internal clock could not be backed up by the battery, e.g. because the battery is
discharged.
● "Supply voltage failed"
The period was prematurely ended due to failure of the supply voltage.
● "Unreliable"
The load profile data is unreliable.
– The measuring current or the measuring voltage is outside the specified range.
– The reactive power type has changed.
The additional information is stored together with the other load profile data and can be
called via the communication interface.

2.5 Tariffs
SENTRON PAC4200 supports two tariffs for the integrated energy counters (on-peak and
off-peak).
A tariff change between off-peak and on-peak can be requested by means of a digital input
or via the communication interfaces.
Time-related switching is only possible using a higher-level system.
The last tariff remains valid until the end of the instantaneous period. The new tariff takes
effect at the start of the next period. The energy counters of SENTRON PAC4200 are
switched to the other tariff at the end of the instantaneous demand period.
Without synchronization, the tariff change takes effect immediately.
