6. Electrical connection

6.1 General

NOTE !

All work on the electrical equip m ent of the special sewing machine may only be conducted by skilled electricians or appropriately instructed persons. The mains plug must be pulled out!

It is absolutely necessary to note the Operating Instructions of the manufacturer, supplied together with the sewing motor!

6.1.1 Connections package and grounding kit

The electrical connections package and the grounding kit are to be found in the accessories pack of the special sewing machine.

The electrical connections package contains all part s necessary for th e electrical connection of the sewing machine head to the sewing drive.

The grounding kit serves for the gr ounding of the sewing m achine head, the knee switch and the mounting plate of the distributor.

6.2 Checking the Mains Voltage

NOTE !

The design vol t age listed on the rat i ng plate of the sewin g drive and the mains voltage must agree.

6.3 Connecting the Sewing Drive

The

direct-current positioning drive

By connection with a 3-phase mains of 3 x 380V, 3 x 400V or 3 x 415V the sewing drive is connected to one phase and the neutral. By connection with a 3-phase mains of 3 x 200V, 3 x 220V, 3 x 230V or 3 x 240V the sewing drive is connected to two phases. When multiple sewing machines are connected to a 3-phase m ai ns, the connections should be distributed equally among the phases in order to avoid the overburdening of a phase. See connection diagram 9800 139001 B

–

Lay the connect i on cable from the mai n switch through the c able duct to the sewing drive and co nnect to the sewing drive.

–

Lay the mains cable from the main switch through the cable duct and fasten with the mains lead cleat.

–

Insert the lead from the commutation adjuster into socket b2 of the drive controls. (Only with a d i rect-current positioning drive) (See section 6.6)

–

Insert the lead from the set-point adjuster into socket (Only with a d i rect-current positioning drive) (See section 6.6)

–

The connection to the mains via a plug connection may only occur when all ground cables (see Chapter 6.4) are attached and the work on the electrical equipment (e.g. connection of the sewing light transformer, Chapter 6.5) is finished.

NOTE !

The connection of the sewing machi ne to the mains mu st occur via a plug connection.

6.4 Potential compensation

6.7 Mounting the Synchronizer

–

Place the synchronizer 3 on the ha ndwheel flange. The groove 6 on the housing of the synchronizer must lock over the twist barrier 5 on the belt guard.

–

Tighten both set scr ews 2 on the synchronizer ring 4.

–

–

Faire passer le câble de raccordeme nt du transmetteur de position latéralement dans la cond ui te de câbles sous la tablette et le poser vers l’avant.

–

Insert the plug of the synchronizer into the socket b1 of the drive controls. (See section 6.6)

6.8 Connecting the Sewing Machine Head

The electrical connection to the sewing machine head occurs via the central plug connection 1.

–

–

Guide the connection lead down through the cutout in the table top.

–

Insert the plug (37-pin) into the socket A of the drive controls. (See section 6.6)

6.9 Direction of Turn o f the Sewing Drive

NOTE !

Before commissioning the special sewing machine it is essential to check the direction of t urn of the sewing dri ve. The operation of the special sewing m achine with an incorrect direction of turn can lead to damage.

The illustration shows the normal direction of turn of the sewing drive. (Counterclockwise rotation = Counterclockwise when viewing the belt pulley)

6.9.1 Checking the Direction of T urn with a DC1600/DA82GA Direct-current

The direction of turn of the direct-current positioning drive is set to counterclockwise rotation via the factory setting of the preset value (= 1) of the parameter F-161. However, the first action during com missioning must be to check the di rection of turn. For this proceed e.g. as follows:

– –

Positioning Drive.

The synchronizer must be mounted. See Chapter 6.7 The plugs of the set-point adjuster, commutation adjuster, synchronizer and control

panel must be i nserted. See pictu re 6.6 Do not insert the 37-pin plug of the sewing machine head. Turn the main switch on.

The control panel shows "Info A5" , this means that no valid autoselect resistor was found and th e m aximum speed is thus limited.

Press the pedal forward slightly; the drive turns; check the direction of turn. Insert the 37-pin plug of the sewing machine head again.

6.9.2 Changing the Direction of Turn with a DC1600/DA82GA Direct-current

If the sewing drive runs with an incorrect direction of turn, the parameter "Technician Level" must be set to the value 1. With V810 cont rol panel see Chapter 6.11.4 With V820 cont rol panel see Chapter 6.11.5

Positioning Drive.

of the

F-161

NOTE !

After a change in the direction of turn the posit i ons must be reset. See Chapter 6.10

6.10 Positioning

6.10.1 Definition of the Positions

Reference position

The reference position is the initial position for all further positions. It is defined as the needle position in which the needle point, with lowered needle in normal direction of turn, lies at the level of the top of the needle plate. After a removal of the synchro ni zer only the reference position must be reset, all further positions, with correctly set controls, are then automatically correct again.

Position 1

In the 1st Position the lower edge of the needle eye of the lowering needle 1 in the normal direction of turn lies at the same height as the hook cover ring 2.

Position 1A

This position is only required for internal functions of the controls, it should lie at least 60 increments after position 1.

Position 2

In the 2nd position the needle bar lies at the upper de ad center.

Position 2A

This position is only required for internal functions of the controls, it should lie at least 60 increments after position 2.

Position 3

This position is not required for the classe 768.

Position 3A

This position is not required for the classe 768.

6.10.2 Setting Positions with a DC1600/DA82GA Direct-current Positioning Drive

6.10.2.1 General

The digital sy nc hronizer sends the controls 512 impulses (increments) and an additional impulse once per revolution. All needle positions are determined by these impulses and by the values of the parame t ers F-170 and F-171.

No mechanical settings are required on the synchronizer.

Attention!

After the following work

1. First operation of the sewing drive.

2. Repla cement of the sewing drive, the drive controls or the cont rol plate of the drive control s.

3. Repla cement of the EPROMs in the drive controls.

If one or both needle positions do not agree with the definitions in Chapter 6.10.1, then a correction of the setting is to be conducted as per Chapter 6.10.2 or 6.10.3.

6.11 Setting Machine-specific Parameters

6.11.1 General

The functions of the controls of the sewing drive are determined by the program and the setting of the parameters.

At delivery of the sewing drives the parameter values have been preset by Efka (preset values). For each class and subclass some parameters at the "Technician" and the "Supplier Level" must be altere d in order to optima l l y adapt the control s to the machine. The affected parameters are listed in the table below and in the parameter sheet (in the accessories pack).

6.11.2 Autoselect

The controls "recognize" by measuring the autoselect resistor, which is found in the machine, which machine series they are connected to. Control functi ons and the preset values of the parameters are selected through autoselect. If the controls recognize no or an invalid autoselect resistor, then the drive only runs with the so-called emergency operation functions in order to protect the mach i n e from damage.

See "EFKA DA82GA 3301" operating instructions

NOTE !

The altering of the parameter values must be conducted very carefully because the machine can be damaged through incorrectly set drive controls! All parameter values can be reset to the delivery stat us (preset values) by a master reset. See Chapter 6.12
