This manual is intended as a rapid guide to the use and operation of the
SUPER PFR
controller
.
Any manipulation or use of the equipment different from that specified by the
manufacturer may compromise user safety
. The apparatus must be disconnected
from the power supply before carrying out any maintenance operation. In the event of
failure in the operation or the protections, the unit must be left out of service and its
reconnection must be prevented until the problem has been corrected.
2.- Connections
A current transformer must be installed for the start-up (
I
n
/ 5 A) depending on the
total current of the load.
The regulator power supply voltage will be two-phase, preferably L1 for
U
L1
and L2
for
U
L2
, and the current will preferably be taken from L1. It must be supplied by
means of an automatic switch. See cable section and protections in the table of
technical features.
The current transformer must be placed in such
a way that it measures the total current of the
loads plus the capacitors.
The transformer for the leakage current must be
placed so that it measures the current in the
capacitor bank and must include lines L1, L2, L3
and N.
The unit has a switched relay exclusively for the alarm outlet.
2.1.- Communications
The
SUPER PFR
regulators can be connected to a computer or another unit by
means of the standard RS-485 bus included. This system is able to focus data
on a single registry point (Power Studio® System).
In a network of equipment, the
SUPER PFR
communicates by question-answer
(slave).
The
SUPER PFR
communicates with the
MODBUS RTU©
protocol, which
enables it to access the electrical parameter and the main variables and
configurations. Contact the manufacturer for the table of addresses.
See section 4.3. to change the communications configuration.
