General purpose

This document is the Designer’s Reference Handbook for DEIF’s Advanced Protection Unit, the

APU 200. The document mainly includes functional descriptions, presentation of display unit, menu

structure, wiring and the procedure for parameter setup.

The general purpose of the Designer’s Reference Handbook is to provide useful overall information

about the functionality of the unit and its applications. This handbook also offers the user the

information needed in order to successfully set up the parameters needed in the user’s specific

application.

Intended users

The handbook is mainly intended for the person responsible for the unit parameter setup. In most

cases, this would be a panel builder designer. Naturally, other users might also find useful

information in the handbook.

Contents/overall structureThe Designer’s Reference Handbook and Installation instructions is divided into chapters and in

order to make the structure of the document simple and easy to use, each chapter will begin from

the top of a new page. The following will outline the contents of each of the chapters.

About this document

2. Warnings and legal information

This chapter includes important information about general legal issues relevant in the handling of

DEIF products. Furthermore, some overall safety precautions will be introduced and

recommended. Finally, the highlighted notes and warnings, which will be used throughout this

handbook, are presented.

Legal information and responsibility

DEIF takes no responsibility for installation or operation of the device connected to the APU 200. If

there is any doubt about how to install or operate the device controlled by the unit, the company

responsible for the installation or the operation of the set must be contacted.

Electrostatic discharge awareness

Sufficient care must be taken to protect the terminals against static discharges during the

installation. Once the unit is installed and connected, these precautions are no longer necessary.

Safety issues

Installing the unit implies work with dangerous currents and voltages. Therefore, the installation

should only be carried out by authorised personnel who understand the risks involved in working

with live electrical equipment.

Definitions

Throughout this document, a number of notes and warnings will be presented. To ensure that

these are noticed, they will be highlighted in order to separate them from the general text.

Notes

Warnings

The notes provide general information which will be helpful for the reader to

bear in mind.

The warnings indicate a potentially dangerous situation which could result in

death, personal injury or damaged equipment, if certain guidelines are not

followed.

Be aware of the hazardous live currents and voltages. Do not touch any AC

measurement inputs as this could lead to injury or death.

The units are not to be opened by unauthorised personnel. If opened anyway, the

warranty will be lost.

4th current transformer input

The 4th current transformer input (terminals 59-60) is used for earth current (ground fault)

measured in the transformer star point ground connection.

The function includes a 3rd

harmonics filtering of the signal. This is selected by activating the

alarm in setting 1730.

The setting of the CT is made in setting 6045 (primary) and 6046 (secondary).

Neutral line and ground fault inverse overcurrent

These are configurable inverse alarms, based on predefined or user-configurable curve shapes.Settings are found in parameter 1730 (G Ie>> Inverse).

Formula and settings used

The inverse time overcurrent is based on IEC 60255 part 151.

The function used is dependent time characteristic, and the formula used is:

k

t(G) = TMS +c

G

- 1GS

where

t(G) is the theoretical operating time constant value of G in seconds

k, c, α are the constants characterising the selected curve

G is the measured value of the characteristic quantity

GS is the setting value

TMS is the time multiplier setting

The constants k and c have a unit of seconds, α has no dimension.

α

There is no intentional delay on reset. The function will reset when G < 2 x G S.

Wire fail detection

If it is necessary to supervise the sensors/wires connected to the multi-inputs, then it is possible

to enable the wire break function for each input. If the measured value on the input is outside the

normal dynamic area of the input, it will be detected as if the wire has made a short-circuit or a

break. An alarm with a configurable fail class will be activated.

7. General setup

Nominal settings

The nominal settings can be changed to match different voltages and frequencies. The APU 200has four sets of nominal values, and they are adjusted in menus 6000 to 6030 (nominal settings

1 to 4).

Activation

The switching between the nominal setpoint can be done in four ways: digital input (M-Logic),

AOP or menu 6006.

Digital input

M-Logic is used when a digital input is needed for switching between the four sets of nominal

settings. Select the required input among the input events, and select the nominal settings in the

outputs.

Example:

Event A Event B Event C Output

Dig. input no. 77 or Not used or Not used Set nom. parameter settings 1

Not Dig. input no. 77 or Not used or Not used Set nom. parameter settings 2

AOP

M-Logic is used when the AOP is used for switching between the four sets of nominal settings.

Select the required AOP push-button among the input events, and select the nominal settings inthe outputs.

Example:

Event A Event B Event C Output

Button 07 or Not used or Not used Set nom. parameter settings 1

Button 08 or Not used or Not used Set nom. parameter settings 2

Menu settings

In menu 6005, the switching is made between settings 1 to 4 simply by choosing the desired

nominal setting.

Fan Control

Four configurable fans can be setup in the APU. The setup of the fans is done in menus 6562 to

6620. It is possible to use the display to setup the fans but it is recommended to setup the fans

via the USW, because then it is possible to see all settings.

Fan Input

Fan temperature input is setup in parameter 6561. This input can be selected between multi-

input 46, 47 or 48.

Fan priority update

At parameter 6562, the priority update rate is selected.

Fan control

Stop/start of the fans is setup in parameter 6563 to 6574.

The following start/stop curve will be generated if a bow setting is used.

If fan priority update is set to 0 hours, the sequence will be fixed to.:

Fan A, Fan B, Fan C and Fan D.

It is recommended to use the USW to setup the fans, because then it is possible

at the same time to overview all four settings.

Fan Output

At parameter 6581 to 6584, the output for fan A to D is selected. If two fans are requested to be

started at the same time, it is possible to add a start delay between the two fans; this is done in

parameter 6586.

Fan A to D Failure

It is possible to activate an alarm if the fan output is not energised. At parameter 6590 to 6620,

the fan failure is setup.

Fan running hour

The running hours is controlled by M-Logic, and each fan output needs to be programmed in

order to have correct running hour values.

The running hour can reset by entering parameter 6585 and select the fan output to be reset.

Please note that it is only possible to reset the value, not add new values.


26/37



Service timers The unit is able to monitor the maintenance intervals. Two service timers are available to cover

different intervals.

The service timers can be setup:

via the display or via the USW

The function is based on energised hours. When the adjusted time expires, the unit will display

an alarm.

The energised hours is counting when the energised feedback is present.

Setpoints available in menus 6110 and 6170:

Enable: Enable/disable the alarm function.

Energised hours: The number of energised hours to activate the alarm.

Day: The number of days to activate the alarm – if the hours are not reached

before this number of days, the alarm will be raised.

Fail class: The fail class of the alarm.

Output A: Relay to be activated when the alarm is raised.

Reset: Enabling this will reset the service timer to zero. This has to be done

when the alarm is activated.

8. Power Management

In the following chapter, the power management functions of the APU 200 are listed.

Power management functions:

• Load management

• Command timers

• CAN flags

Load management

The function is used to activate a relay when a specific amount of power is available. Each APU

200 has five levels which are adjusted in menus 8220-8260:

• Available power 1


• Available power 3• Available power 4


These setpoints can activate a relay when the specific amount of available power is reached.

The relay output can be used to connect load groups when sufficient power is available. The

relays will activate when the available power is higher than the setpoint, but be aware that when

the load groups are being connected, the available power will decrease and the relay(s)

deactivate again if the available power is below the setpoint. So it is necessary to make an

external holding circuit.

The function is not depending on the running modes. The relays will activate in all modes

including block. To avoid activation, e.g. when the APU is blocked, the inhibit function should beused.

Command timers (time-dependent start/stop)

The purpose of the time-dependent start/stop function is to be able to start and stop functions

automatically at specific times each weekday or certain weekdays.

Up to eight command timers can be used for either start or stop functions. The settings are set

up through the PC utility software. Each command can be set for the following time periods:

• Individual days (MO, TU, WE, TH, FR, SA, SU)

• MO, TU, WE, TH

• MO, TU, WE, TH, FR

•

MO, TU, WE, TH, FR, SA, SU• SA, SU

The command timers are to be used in M-Logic as events to set the command (start/stop).

It is necessary to use the PC utility software when setting up the time-dependent

start/stop function.

The time-dependent start and stop commands are pulses that are not sent until

the moment the adjusted time is reached.

9. Additional functions

This chapter includes functional descriptions of functions. Tables, diagrams and single-line

illustrations will be used in order to simplify the information.

Alarm inhibit

In order to select when the alarms are to be active, a configurable inhibit setting for every alarm

has been made. The inhibit functionality is only available via the PC utility software. For every

alarm, there is a drop-down window where it is possible to select which signals that have to be

present in order to inhibit the alarm.

Selections for alarm inhibit:

Function Description

Inhibit 1 M-Logic outputs:

Conditions are

programmed in M-Logic

Inhibit 2

Inhibit 3

BTB ON The bus breaker is closed

BTB OFF The bus breaker is open

BA voltage > 30% Bus A voltage is above

30% of nominal

BA voltage < 30% Bus A voltage is below

30% of nominal

Inhibit of the alarm is active as long as one of the selected inhibit functions is active.

In this example, inhibit is set to BTB ON . Here, the alarm will be active when the BTB is not

closed. When the BTB has been synchronised, the alarm will be disabled again.

Access lock

The purpose of access lock is to deny the operator the possibility of configuring the unit

parameters and changing the running modes.

The input to be used for the access lock function is defined in the PC utility software (USW) I/O

settings, please use the application help [F1] in the USW for additional information of how to

programme the device.

The following example is digital input 86 (terminal 86) used for access lock

Access lock will typically be activated from a key switch installed behind the door of the

switchboard cabinet.

Fail class

All activated alarms must be configured with a fail class. The fail classes define the category of

the alarms and the subsequent alarm action.

Three different fail classes can be used. The tables below illustrate the action of each fail class

The table illustrates the action of the fail classes. If, for instance, an alarm has been configured

with the “Trip BTB” fail class, the following actions occur:

• The alarm horn relay will activate.

•

The alarm will be displayed in the alarm info screen.• The BTB will open instantly.

Fail class configuration

The fail class can be selected for each alarm function either via the display or via the USW. To

change the fail class via the USW, the alarm function to be configured must be selected. Select

the desired fail class in the fail class scroll-down menu.

M-Logic

M-Logic functionality is included in the unit and is not an option-dependent function. However,

selecting additional options can increase the functionality.

M-Logic is used to execute different commands at predefined conditions. M-Logic is not a PLC

but substitutes one if only very simple commands are needed.

M-Logic is a simple tool based on logic events. One or more input conditions are defined, and at

the activation of those inputs, the defined output will occur. A great variety of inputs can be

selected, such as digital inputs, alarm conditions and running conditions. A variety of the outputs

can also be selected, such as relay outputs, change of modes and change of running modes.

The main purpose of M-Logic is to give the operator/designer more flexible possibilities of

operating the system.

The M-Logic is part of the PC utility software 3, and as such it can only be

configured in the PC utility software and not via the display.

Please refer to the “Help” function (F1) in the PC utility software for a full

description of this configuration tool.

Please refer to DEIF standard application note: “M-Logic” for further functional

details.

Configurable alarm LEDs

The four LEDs on the left side of the display can be controlled via M-Logic. For each LED, there

is a choice between three colours (red, green and yellow) with or without blinking.

Example of Alarms LED configuration

It is possible to programme the Alarm LEDs, to indicate highest phase current at any alarm.

Start by programming the event A to un-acknowledge alarm, then programme event B to look athighest phase (L1, L2 or L3) current at any alarm.

Next step: Alarm LED to be active (LED 1, 2, 3 or 4), also which colour and effect this LED must

have.

The following programming will activate (steady red) Alarm LED 1, whenever an

un-acknowledge alarm is present, and the current was highest in L1 when the

alarm was activated.


35/37



Templates

For each LED, there is a text box, where the indication of the function can be written. This must

be done on a piece of stiff paper or a plastic transparent, as the texts are to be sided into a slot

at the top of the APU 200 unit.

The slide-in paper/transparent template looks like this:

The above template is scale 1:1 when printing on A4 paper size.

USW communication

It is possible to communicate with the unit via the PC utility software. The purpose is to be able

to remote-monitor and control the protection application.

Application settings

Please refer to the PC utility software help file [F1].

Safety

If communication fails, the unit will operate according to the received data. If e.g. only half of the

parameter file has been downloaded when the communication is interrupted, the unit will use

this actual data.

TCP/IP

DEIF option N is an Ethernet hardware option offering a number of features (hereafter referred

to as the option N). The hardware needed for the option N is placed with an RJ45 connector on

the left side of the unit, seen from the rear.

The option N is delivered through the Ethernet port, and we recommend using a twisted pair

category 5 cable (CAT5 as defined in ANSI/TIA/EIA-568-A) for connection of the option N to the

network.

The option N port automatically detects the cable type, so both twisted and straight cables can

be used.

DEIF A/S reserves the right to change any of the above.

It is possible to remote-control from the PC utility software if a TCP/IP router isused. Take precautions that it is safe to remote-operate the system, to avoid

personal injury or death.
