Safety Instructions

Overview	This chapter contains safety instructions which must be complied
	with during installation, operation and maintenance of the power
	converters series DCS 500B / DCF 500B or DCP 500B. If these in-
	structions are not complied with, this may result in injuries (perhaps
	even with fatal) or in damage to the power converter, the motor and
	the driven machine. Before starting with any work whatsoever at or
	with this unit, you must read the information given in this chapter.
Warnings	Warnings provide information on states which if the specified pro-
	cedure for the state concerned is not meticulously complied with
	may result in a serious error, in major damage to the unit, in injury
	to persons and even in death.
	They are identified by the following symbols:
	Danger: High Voltage! This symbol warns you of
	high voltages which may result in injuries to persons
	and/or damage to equipment. Where appropriate, the
	text printed adjacent to this symbol describes how
	risks of this kind may be avoided.
	● All electrical installation and maintenance work on the thyristor
	power converter must be carried out by properly qualified staff
	who have been thoroughly trained in electrical engineering.
	● The thyristor power converter and its adjacent units must be
	properly earthed by qualified professionals.
	● You must NEVER perform any work on the thyristor power con-
	verter while it is still switched on. First switch the unit off, use a
	measuring instrument to make absolutely sure that the power
	converter has really been de-energized, and only then you may
	start with the work concerned.
	● Due to external control circuits, there may be dangerously high
	voltages present at the thyristor power converter even after the
	line voltage has been switched off. So always work at the unit
	with appropriate caution! Non-compliance with these instructions
	may result in injury (or even death!).

Safety Instructions

General warning: this symbol warns you of nonelectrical risks and dangers which may result in serious or even fatal injury to persons and/or in damage to equipment. Where appropriate, the text printed adjacent to this symbol describes how risks of this kind may be avoided.

●When thyristor power converters are in use, the electric motors, power transmission elements and the driven machines are working in an extended operating range, which means they have to cope with a relatively high loading.

●You should have made sure that all units, devices and appliances used are actually suitable for this higher loading.

●If you have to operate the thyristor power converter at a rated motor voltage and/or a rated motor current significantly below the figures stated in the thyristor power converter's output data, you must take appropriate precautionary measures to protect the unit against overspeed, overload, breakage, etc., by modifying the software or hardware appropriately.

●For insulation testing, you must disconnect all cables from the thyristor power converter. You should avoid operating your unit at values other than the rated data. Non-compliance with these instructions may cause lasting damage to the thyristor power converter.

●The thyristor power converter possesses a number of automatic reset functions. When these functions are executed, the unit will be reset after an error and will then resume operation. These functions should not be used if other units and devices are not suitable for an operating mode of this kind, or if their use might entail dangerous situations.

Warning of electrostatic discharge:

this symbol warns you against electrostatic discharges which may damage the unit. Where appropriate, the text printed next to this symbol describes how a risk of this kind may be avoided.

Safety Instructions

Notes supply information on states requiring particular attention, or indicate that additional information is available on a specific topic. For this purpose, the following symbols are used:

CAUTION! Cautions are designed to draw your attention to a particular state of affairs.

Note	A note contains or refers you to additional informa-
	tion available on the particular topic concerned.

You can use a switch disconnector (with fuses) in the power supply of the thyristor power converter to disconnect the electrical components of the unit from the power supply for installation and maintenance work. The type of disconnector used must be a switch disconnector as per EN 60947-3, Class B, so as to comply with EU regulations, or a circuit-breaker type which switches off the load circuit by means of an auxiliary contact causing the breaker's main contacts to open. The mains disconnector must be locked in its "OPEN" position during any installation and maintenance work.

EMERGENCY STOP buttons must be installed at each control desk and at all other control panels requiring an emergency stop function. Pressing the STOP button on the CDP 31x control panel of the thyristor power converter will neither cause an emergency motor stop, nor will the drive be disconnected from any dangerous potential.

The operating instructions cannot take into consideration every possible case of configuration, operation or maintenance. Thus, they mainly give such advice only, which is required by qualified personnel for normal operation of the machines and devices in industrial installations.

If in special cases the electrical machines and devices are intended for use in non-industrial installations - which may require stricter safety regulations (e.g. protection against contact by

children or similar) -, these additional safety measures for the installation must be provided by the customer during assembly.

Chapter 1 - Introduction

Incoming inspection	After opening this package, you should check whether it contains
	the following items:
	● DCS 500B / DCF 500B or DCP 500B thyristor power con-
	verter in the configuration ordered
	● DCS 500B / DCF 500B or DCP 500B publications
	● Accessories, including manuals if ordered
	● Final test report
	Check the consignment for any signs of damage. If you find any,
	please contact the insurance company or the supplier.
	Check the particulars given on the unit's rating plate to make sure
	prior to installation and start-up that you have received the correct
	unit type and unit version.
	If the consignment is incomplete or contains any incorrect items,
	please contact the supplier.
	CAUTION! The thyristor power converter weighs quite a lot and
	should therefore not be held by the front cover. Please put the unit
	down only on its back (sizes C1/C2/A5). Always use care when
	handling the unit, so as to avoid injuries or damage.
Storage and transport
	If the unit had been in storage prior to installation or is transported
	to another location, care must be taken to ensure that the environ-
	mental conditions are complied with (see "System Descriptions
	DCS 500B / DCF 500B or DCP 500B").
Rating plate	For purposes of identification, each thyristor power converter is fit-
	ted with rating plates, stating the type code and the serial number,
	which serve for each unit's individual identification.
	The type code contains information on the characteristics and the
	configuration of the unit. The first three digits of the serial number
	refer to the year and week of manufacture. The last digits complete
	the serial number so as to preclude two units receiving the same
	type code and the same serial number.
	The 112xx group provides information on the unit's software con-
	figuration.
	The technical data and specifications are valid as of going to press.
	ABB reserves the right to make subsequent alterations.
	If you have any questions concerning your drive system, please
	contact your local ABB agent.

General notes

CAUTION: it is absolutely essential that the applicable accident prevention regulations be observed by the user (in this context, please also read the chapter entitled "Safety Instructions")!

How this chapter is structured

For better understanding the individual steps of start-up work are distinguished by a) frames without any additional marking on the left side:

These steps of start-up work must always be performed (= mandatory start-up work)!

Example:

522 = GERMAN [Only with the SDCS-CON-2 control board & the CDP 312 panel!]

b) frames with marking on the left side („columns“ shaded in grey):

These steps of start-up work have to be performed only when the condition stated (as heading) applies to the selected drive configuration! After this work has been completed, the mandatory start-up work has to be continued.

Example:

Only when connection diagram 1 (Appendix A) is being used!

Chapter 2 - Start-Up Instructions

Phase sequence when connecting to the mains / Potential isolation

No special phase sequence required for the main connections U1, V1 and W1!

Phase coordination between electronics section and power section not necessary!

For potential isolation and for avoiding ground loops, an isolating transformer should be installed upstream when an oscilloscope is being used.

Preventing unintended operating states / Shutting the drive down

CAUTION! As laid down in DIN 57100 Part 727 / VDE 0100 Part 727 (Preventing unintended operating states), shutting the drive down by means of the signals at the binary inputs DIx is not sufficient in itself as the sole measure involved for avoiding unintended operating states or shutting the drive down in the event of danger!

Range of application for the Start-Up Instructions

The Start-Up Instructions are referenced to the parameter settings in their as-delivered condition (default values) and to the unit wiring as shown in connection diagram 1 or 2 (see Appendix A). In both circuit variants, the binary inputs DI5, DI7 and DI8 can be used. They will cause the reactions at the drive as described below.

The symbols stated in this context will be repeatedly used further on in the text.

Method of functioning of the binary inputs DI5, DI7 and DI8

•Binary input DI5; designation EM STOP

In operation, DI5 must be set to logical "1“. If it is set to "0“, the alarm signal A 102 will appear. The drive will react in accordance with the function set at Parameter 917 (shutdown with ramp, with torque limit/current limit, with controller blocking and

coasting). Once ramp-down has been completed (speed feedback below nmin), the output is reset for controlling the line contactor. After that, the EM STOP input

should be set back to "1“, the alarm message acknowledged, and the ON/OFF input likewise be set to "0“. After that, the drive can be started anew.

•Binary input DI7; designation ON/OFF

For connecting the drive to the mains, DI7 must be set to logical "1“. If there are no

ongoing faults, the outputs for controlling the contactors for the armature circuit and

the field circuit will be activated. If DI7 is set to "0“, the controllers will be blocked internally and the outputs reset after a time-delay.

The function which can be set with Parameter 915 (inputs DI7 and DI8 for switching the contactors) will only be operative when the drive has been wired as shown

in connection diagram 2.

	- Switch OFF electronics	X6: 7 „0“ signal
	- Switch OFF power		(input ON / OFF)
		(K20 in connection example)

•Binary input DI8; designation RUN

For starting the drive, DI8 must be set to logical „1“. This enables the reference at the REF_SEL and RAMP GENERATOR blocks, as well as the controllers. If DI8 is set to "0“, the drive will react in accordance with the function set at Parameter 916 (shutdown with ramp, with torque limit/current limit, with controller block and coasting).

Once ramp-down has been completed (speed feedback below nmin), the reference is kept at zero, and the controllers blocked after a time-delay; the drive is torqueless.

Symbols for enabling / disabling the reference

				- ENABLE reference	X6: 8	„1“ signal	(input RUN)
					(K21 in connection example)
				- DISABLE reference	X6: 8	„0“ signal	(input RUN)
					(K21 in connection example)

System-dependent planning

If you want the drive to react with a function other than that of Parameter 916 or 917, you have to parameterize the unit accordingly, by connecting one of the inputs or an additional one with a control pin, e.g. at the ramp-function generator.

- Example 1:

Operational ramp-up and ramp-down in the event of reference changes with the same ramp times, shutdown via RUN with a different time.

Solution:

use second parameter set ramp times; set time at DECEL2; establish connection from P 1707 to P 10716.

- Example 2:

Implementing an EMERGENCY SHUTDOWN or EMERGENCY STOP function. Solution:

this function stipulated in various regulations must always be planned in dependence on the system involved! A basic distinction must be made here between electrical and mechanical risks. Since one signal at one input is not sufficient (see above), at least one other switch-off option must be created, e.g. by means of a relay directly switch-

ing input DI5 to "0“. This is how the power converter attempts (in accordance with P 917), to defuse the dangerous situation. A dropout-delay contact of the relay will

then switch the power off. If the delay is small or does not match the function selected for P 917, then certain operating states (regeneration) may, due to laws of physics, result in the unit fuses tripping, and in extreme cases in thyristor defects.

2.1 Preparatory work

Check the unit for damage in transit or other damage.

Install and wire unit; connect all inputs and outputs required.

Proceed in the same way for the field supply unit as well.

Check whether protective measures, earthing, screening, etc. have been taken in accordance with the system conditions involved.

Check the rated value of the supply voltage for the electronics and the fan:

•matching transformer necessary when:

-electronics supply is not equal to 115 V/230 V

-single-phase-fan supply is not equal to 230 V

-three-phase-fan supply is not within the range of 400 V .... 690 V.

Check the rated value of the supply voltage for the armature-circuit converter's power section; the particulars given on the rating plate must be > than the rated line voltage.

If this condition is not satisfied, then the following applies:

-use an isolating transformer, or

-use a suitable unit.

Check the rated value of the supply voltage for the field supply unit. (Particulars on rating plate > rated line voltage?

Is an auxiliary transformer or perhaps a series resistor necessary?)

Check the wiring, fusing, the cross-sectional areas of the cables.

Provide an option for switching binary inputs X6: 7 and X6: 8.

Check the system's EMERGENCY STOP for proper functioning! Set the system-side monitoring functions, and activate them. Check whether auxiliaries, such as motor fans or unit fans, function properly; while doing this, also check for correct direction of rotation and voltage level as well!

Chapter 2 - Start-Up Instructions

2.3 Presetting the field supply unit

Make sure that existing supply voltages for power section, field supply unit (field exciter) and field winding, fan, etc. match the rated data of the components used.

Switch ON power.

DANGER: System components now energized!

Please wait a few moments. During this time, the unit compares the phase sequence set in the parameter with that obtaining at the power section.

If the unit outputs the "Phase sequence fault of power section“ signalF( 38):

-switch off unit completely and disconnect from the mains, interchange two phases at the input, and start again from the beginning of this chapter.

or

- enter: 506 = R-T-S and then acknowledge fault signal.

Unit will automatically adapt to phase sequence; this signal is to be interpreted as information to the effect that the fans' direction of rotation may be wrong for size-C4 units.

Only for uncontrolled field supply with SDCS-FEX-1!

505 = 1 Panel display: DIODE FIELD EXCIT

Check field current and field voltage by measuring them.

Switch OFF power!

11202 = SAVE MOT1 SET

Save the altered values in the non-volatile memory!

Continue with Chapter 2.4

Only for controlled field supply with SDCS-FEX-2 or DCF 503/DCF 504!

			505	= 2	Panel display: FEX2 OR FEX3
			503	= Rated motor field current

Scales all parameters referenced to the motor field current, such as field current limitation or field current monitoring

1305 = Field current for "Under-excitation" signal

Check field current and field voltage by measuring them; if necessary, correct field current with 503.

	1201 = 5	Panel display: FEX2/3 AUTOTUNING

Activates the field current controller's auto-tuning function.

Action has been completed when NOT ACTIVATED is shown on the display.

Switch OFF power!

11202 = SAVE MOT1 SET

Save the altered values in the non-volatile memory!

Continue with Chapter 2.4

Only for controlled field supply with DCF 501B or DCF 502B !

505 = 2 Panel display: FEX2 OR FEX3

503 = Rated motor field current

Scales all parameters referenced to the motor field current, such as field current limitation or field current monitoring.

If field current is above 150A, multiply the value by 0.1 and use this number (problem: upper limit of P503 / P504) ; the reference transferred to the DCF 500B is always 100% independent of this setting; by doing so all indications on the panel CDP312 can be corrected quite easily by multiplying by 10

1305 = Field current for "Under-excitation" signal

Switch OFF power!

11202 = SAVE MOT1 SET

Save the altered values in the non-volatile memory!

Before adjustment of the armature-circuit power converter is continued (Chapters 2.4 etc.),

First perform the start-up routine for the DCF 501B or DCF 502B field supply unit (Chapter 2.9) and

then: continue with Chapter 2.4

2.4 Adjusting the current controller

Make sure that static current limitation Bridge 1 (2307) and Bridge 2 (2308; with 4Q-unit) have been set to the same value; values of all parameters for current reference limitation must be greater than 20 %; conditions have been satisfied if default setting has been taken as starting point; setting to maximally required motor current is recommended.

Drive must not turn! Do not preset an external reference!

1201 = 3 Panel display: ARM. AUTOTUNING

Activate the current controller's auto-tuning function.

Start the next two steps within the next 20 seconds!

Switch ON power.

DANGER: System components now energized!

Start drive.

When the display shows NOT ACTIVATED (action correctly completed), stop drive; it may happen that the unit runs armature-circuit current since e.m.f. control is active; nmin - signal (2201) value too small.

Switch OFF power!

If the unit aborts the auto-tuning routine with a fault signal, then eliminate cause of this as far as possible (supply, switching sequence, etc.; see also

description for 11201), then repeat the above points, or continue with next point.

Read out values of:
407 = ............	408 = ............	409 = ............	410 = ............	411 = ............

Only if the unit aborts the auto-tuning routine with a fault signal FIELD REMOVAL?!

	505	= 0	Panel display: NO FIELD EXCITER
	11202	= SAVE MOT1 SET

Save the altered values in the non-volatile memory!

Switch OFF power supply to the electronics section! If the SDCS-FEX-1 field supply is being used: make sure that no field current is flowing, e.g. by removing the supply fuses!

Switch the electronics section's power supply on again!
