Brief description

The A 210 is a panel mounting instrument for monitoring AC systems
with dimensions 96 x 96 mm. The following measurements are
acquired: voltages, currents, frequency, and phase angles in single
phase or 3 phase systems. From these, the active power, reactive
power, apparent power, active energy, reactive energy, and the power
factor and the neutral current can be calculated. With the use of
voltage and current transformers, the instrument can be used for
measurements in medium and high voltage systems. The trans-
formation ratios are configurable for the direct display of all
measurements. The A 210 instrument is used as a display with two
S0 pulse or limit value outputs.

Pulse/Limit value outputs
Depending on the function selected, the two digital outputs can be
used either as pulse outputs for actual and reactive energy or as
limit signals
The outputs are passive, and are galvanically isolated from all the
other circuits by opto-couplers.
External voltage source:
Load current:
Pulse outputs
The values for measured reactive and active energy can be read out
at the pulse outputs in the form of standard S0 pulses for the driving
of electromechanical counting mechanisms (pulse duration
>100 mA).

Commissioning

The multi-functional instrument is made operational by switching
on the power supply. The following appears sequentially on the
display:
1. Segment tests: all the segments of the displays and all the LEDs
are lit for 2 s.
2. Version of the software: e.g.: A 210
3. The 3 line voltages at switching on.
Loss of the power supply
All the values configured remain during a loss of the power supply.
On reconnecting the power supply, the last mode selected is
displayed.
