Datakom Dfc-0108 User manual

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.

* 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.

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

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

SAFETY NOTICE

Failure to follow below

instructions will result in

death or serious injury

DISPLAY

Although the unit is protected against

electromagnetic disturbance, excessive

disturbance can affect the operation and

measurement precision.

ALWAYS remove plug connectors when

inserting wires with a screwdriver.

Fuses must be connected to phase voltage

inputs, in close proximity of the unit. Fuses

must be of fast type (FF) with a maximum

rating of 6A.

Use cables of appropriate temperature

range and section, at least 0.75mm2

(AWG18).

For current transformer inputs, use at least

1.5mm2section (AWG15) cable.

The current transformer cable length

should not exceed 1.5 meters. If longer

cable is used, increase the cable section.

5A Current transformers must be used.

ELECTRICAL INSTALLATION

BUTTON

FUNCTION

In AUTO mode, acknowledges the displayed alarm.

If the same alarm occurs again, it will not appear on the display.

HELD PRESSED DURING 5 SEC:

Resets all alarms and the alarm led.

Any new coming alarm will appear on the display.

HELD PRESSED DURING 10 SEC AT POWER-ON:

The unit enters automatic setup mode.

Switch to upper display or previous parameter

or increase related value (programming mode)

Switch to lower display or next parameter

or decrease related value (programming mode)

HELD PRESSED DURING 5 SEC:

Switches between AUTO and MANUAL modes. In MANUAL mode the

stepping is disabled. From the MANUAL mode TEST mode can be

selected in order to test each step manually.

HELD PRESSED DURING 5 SEC IN MANUAL MODE:

Switches between MANUAL and TEST modes. In TEST mode, all steps

may be turned on and off manually. For more detailed information

please check chapter 4.2.

HELD PRESSED TOGETHER DURING 5 SEC:

Enters or exits programming mode.

PUSHBUTTON FUNCTIONS

In TEST mode only the total kVAr value is displayed.

When TEST mode is selected then the step-1 indicator led will flash. Pressing the

pushbutton will activate this step. Pressing the pushbutton will deactivate this step.

Pressing the MENU pushbutton will select the next step and the related step led will

flash. Using pushbuttons the step may be activated or deactivated.

Using the MENU pushbutton all steps may be scrolled manually.

In TEST mode, if no button is pressed during 1 minute the

unit will automatically return back to MANUAL mode.

Holding the pushbutton pressed for 5 seconds

switches between TEST and MANUAL modes

TEST MODE, MANUAL STEP CONTROL

In automatic setup mode, the unit ::

-automatically detects and corrects reverse connected current transformers.

-automatically measures and memorizes capacitor bank ratings.

It is preferable that there should be no other load on the

capacitor panel. However with constant or slow changing

loads the unit is able to perform auto setup.

If there are fast changing loads, the unit may be unable to

correct CT polarity errors or may read incorrect bank

capacitor ratings. In such cases, auto setup should be

repeated and capacitor ratings should be

checked/corrected through PROGRAMMING menu.

For a successful auto setup, current transformers must

be connected to correct CT inputs. The connection

polarity is not important.

Otherwise the unit will give ALARM_03 and will not

perform automatic setup.

For a successful auto setup, STEP_1 capacitors must be

3 phased.

Otherwise the unit cannot detect connection errors, gives

ALARM_02 and will not perform automatic setup.

For a successful auto setup, voltage connections must be

3 phased.

Otherwise the unit will give ALARM_01 and will not

perform automatic setup.
