DFC-0108 POWER FACTOR CONTROLLER
8 BANKS, HARMONIC DISTORTION
DISPLAY
DFC-0108 is a high technology controller
allowing the power factor of the installation to
be stabilized to the requested value by
switching capacitor banks through contactors.
The unit allows also the visualization of
various AC parameters like a network
analyzer.
The unit makes harmonic analysis up to the
31th component. The THD values of all
voltages and currents are available.
Stepping algorithms are selectable between
various types. Thanks to the automatic setup
function, the commissioning and programming
are made easy.
SAFETY NOTICE
Failure to follow below
instructions will result in
death or serious injury
* Electrical equipment should be installed only
by qualified specialist. No responsibility is
assured by the manufacturer or any of its
subsidiaries for any consequences resulting
from the non-compliance to these instructions.
* Check the unit for cracks and damages due
to transportation. Do not install damaged
equipment.
* Do not open the unit. There is no
serviceable parts inside.
* Fuses of fast type (FF) with a maximum
rating of 6A must be connected to phase
voltage inputs, in close proximity of the unit.
* Disconnect all power before working on
equipment.
* When the unit is connected to the network
do not touch terminals.
* Short circuit terminals of unused current
transformers.
* Any electrical parameter applied to the
device must be in the range specified in the
user manual.
* Do not try to clean the device with solvent or
the like. Only clean with a dry cloth.
* Verify correct terminal connections before
applying power.
* Only for front panel mounting.
INSTALLATION
Before installation:
Read the user manual carefully, determine
the correct connection diagram.
Remove all connectors and mounting
brackets from the unit, then pass the unit
through the mounting opening.
Put mounting brackets and tighten. Do not
tighten too much, this can brake the
enclosure.
Make electrical connections with plugs
removed from sockets, then place plugs to
their sockets.
Be sure that relay outputs are not
overloaded. If necessary use extra
contactors.
Below conditions may damage the device:
Incorrect connections.
Incorrect power supply voltage.
Voltage at measuring terminals beyond
specified range.
Current at measuring terminals beyond
specified range.
Overload or short circuit at relay output
Current Transformers must be
used for current measurement.
No direct connection allowed
Below conditions may cause abnormal
operation:
Power supply voltage below minimum
acceptable level.
Power supply frequency out of specified
limits
Current transformers not matching related
phases.
Current transformer polarity incorrect.
Inadequate on-delay setting
Inadequate off-delay setting
