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 if 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 owing to a synchronization irregularity.
●
"Supply voltage failed"
The period was prematurely ended owing to the 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.

Tariffs
SENTRON PAC4200 supports two tariffs for the integrated energy counters (on-peak and
off-peak).
Impact of the tariff change
The tariff change affects all energy counters for active energy, reactive energy, and apparent
energy.
Controlling the tariff change
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.
