6. REGULATIONS
6.1 INSTRUCTION FOR THE USE OF AUTOMATIC PFC CONTROLLER PCRL Series
PCRL
is an Automatic PFC Controller, based on a Microprocessor controlled circuit, able to Switch-ON and OFF the banks needed to
maintain the selected Power Factor.
The instrument effects an RMS value measurement that allows the optimal operation and visualization even in presence of distorted
waveformes.
The Microprocessor Central Unit, is able to manage all the regulations:
Microprocessor PFC Controller
LCD Display
Membrane Keyboard, 4 keys
Serial TTL-RS232 for set-up and automatic Test via PC.
Internal temperature sensor.
Advanced function (current measurement, capacitor overload, week Power Factor, storing od mx value).
PCRL is able to recognize se sense of current of C.T. In case of co-generation plants, is necessary to disable this option (see chapter
advanced Menù) and provide to the correct connection of c.t.
The Secondary must be Earth-connected.
A.
Attention: the parameters of PCRL are already Preset and
must not be changed.
B.
The only parameters that the User need to set is the value of the
Primary of C.T.
1.
When the Automatic PFC will be connected, the Display of PCRL will
show
C t (Current Transformer)
flashing.
2.
Press or for setting directly the current value of the
Primary of C.T.
3.
Press
for confirming.
4.
Wait a few seconds.
5.
