DK-40 COMPRESSOR CONTROLLER

INTRODUCTION

DK-40 is a state of the art unit for the control

of both screw and piston type compressors.

The unit integrates all functions needed in a

compressor system. Thus no extra units are

required in a compressor panel providing

cost reduction and simplicity.

The unit is directly powered from 230/400 volt

mains. It provides power supply for fault

switches and sensors. Thus external

transformer is not required in the panel.

The unit monitors mains phase voltages and

frequency. It features high/low voltage and

phase order protections.

The standard logic level serial port features

MODBUS communication. The unit allows

monitoring and programming through

computer.

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 must be connected to the power supply and phase

voltage inputs, in close proximity of the unit.

•

Fuses must be of fast type (FF) with a maximum rating of

6A.

•

Disconnect all power before working on equipment.

•

When the unit is connected to the network do not touch

terminals.

•

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.

•

1. 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.

•Note that the power supply terminal is separated from measurement terminals.

Below conditions may damage the device:

•Incorrect connections.

•Incorrect power supply voltage.

•Voltage at measuring terminals beyond specified range.

•Connecting or removing data terminals when the unit is powered-up.

•Overload or short circuit at relay outputs

•Voltage applied to digital inputs over specified range.

•High voltage applied to communication port.

Below conditions may cause abnormal operation:

•Power supply voltage below minimum acceptable level.

•Power supply frequency out of specified limits

1.3 ELECTRICAL INSTALLATION

Do not install the unit close to high electromagnetic noise

emitting devices like contactors, high current busbars,

switchmode power supplies and the like.

Although the unit is protected against electromagnetic disturbance, excessive disturbance

can affect the operation, measurement precision and data communication quality.

•ALWAYS remove plug connectors when inserting wires with a screwdriver.

•Fuses must be connected to the power supply and 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.

•Use adequate cable section, at least 0.75mm

(AWG18).

•Follow national rules for electrical installation.

•Use only the appropriate cable and connector for serial port connection.

3. DISPLAY NAVIGATION

Usually the upper display shows the pressure-1 value or the pressure switch-1 position.

The lower display shows the temperature-1.

Other values are scrolled by pressing the MENU

button. For better clarity, the upper

display will show the parameter name and the lower display will show the parameter value.

Some parameters are longer than 1 display. For these parameters, when MENU

button

is presssed the parameter name apeears on the upper display. When MENU button is

released, the parameter value is shown on both displays.

Display of some parameters are selectable with program parameters and

may differ following compressor manufacturers.

In the occurrence of a fault condition, the fault code will appear on the

upper display.

Below is a list of messages shown on the upper display in normal operation,

programming and alarm display modes:
