This second generation of
microprocessor module combines all the visualization and
control functions needed to
couple a generator to a bus bar
manually: display of the phase,
frequency and voltage differences, a safety relay which monitors these three parameters
and indicates the status of the
installation.
This new version does not need
an external DC power supply,
as it takes it from the busbar.
The reduced size allows the
use of DIN92 format tools and
its heavy duty metal case can
operate in extreme environment.

SYNCHRONIZATION COLUMN

Led synchroscope:
18 LEDs spread over 360° display the phase difference. The synchroscope
lines up when the frequency difference is less than 0.5 Hz.
Differential frequency meter:
The frequency difference is displayed by a 17 LED bar graph corresponding to ± 5 Hz with an expanded scale over 1 Hz.
Differential voltmeter:
The voltage difference is displayed by a 17 LED bar graph corresponding
to ± 20%.

SAFETY RELAY

The coupling authorization relay monitors the difference in frequency,
voltage and phase. It authorizes coupling only when all the parameters
meet the requirements of the installation.
Frequency difference:
Coupling authorization is given for a frequency difference of less than 0.1 Hz.
Phase difference:
The phase difference which authorizes coupling is adjustable between ±
5° and ± 20°.
Voltage difference:
The voltage difference which authorizes coupling is adjustable between
± 2.5% and ± 20%.
