3.7
Behavior in the case of power failure and power restore
After a power failure, the device starts back at zero with the calculation of the power demand
of the total active power and total reactive power.
Counter statuses and maximum/minimum values are written from the volatile to the non-
volatile memory at the following intervals:

Digital inputs and outputs
SENTRON PAC3200 has:
● one multifunctional digital input,
● one multifunctional digital output.
Digital output
The following functions can be assigned to the digital output:
● Energy pulse output, programmable for active energy pulses or reactive energy pulses
● Indication of the direction of rotation
● Displaying the operating status of the SENTRON PAC3200
● Signaling limit violations
● Switching output for remote control via the interface
Energy pulse output
The digital output supplies a number of pulses proportional to the energy measured.
Figure 3-6
The digital output is passive and implemented exclusively as a switch.
Implementation of the pulse function corresponds to the IEC 62053-31 standard.
