6.1 General

NOTE !

Any work on the electrical equipment of t he special sewi ng machine should be carried out exclusively by qualified electricians or by accordingly instructed persons. The mains plug must have been pulled out!

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

Connection package and grounding set

The electrical connection package and the grounding set are included in the accessories of the special sewing machine.

The connection package includes all parts that are necessary for the electrical connection of the sewing machine head to the sewing motor.

The grounding set serves for grounding the sewing machine head. For connecting, see chapter 6.7.

6.2 Checking nominal voltage

NOTE !

The rated voltage and the nominal voltage, stated on the rating plate, must agree.

The direct current drives, where used, are driven by single-phase alternating voltage. For avoiding overloading of a single phase when connecting several machines to a three-phase m ains, please note the followi ng:

The connections of the indivi dual machines mu st be evenly dist ri buted to the phases of the three- phase mains (fo r cabling, see the circuit d i agram).

6.8 Checking the direction of rotation

NOTE !

It is absolutely necessary to check the direction of rotation of the sewing motor prior to putting the special sewing machine into operation. Damages can result if the special sewing machine is started to run in the wring direction of rotation.

The arrow in the illustration shows the proper direction of rotation (

rotation)

The special sewing machines, that are supplied fully assembled, have been factory-set for the

If the special sewing machine is supplied by single components, check the direction of rotation.

The direction of rotation is set on the control panel by means of the parameter (drE).

For checking the di rection of rota t i on:

– – –

–

counter clockwise rotation

Introduce the mains plug. Turn on main switch. Call on the control panel the parameter

The parameter must be set to the value " 1 " (counter clockwise rotation). If required, correct the parameter value.

NOTE !

Following a change of the direction of rotation, the positions must be programmed once again.

6.9 Checking the positionin g

Reference position

The reference position is the starting point for all factory-set positions. In the reference position, the point of the lowered needle stands level with the top of the throat plate.

Position 1

The 1st position serves for starting the cutting process if the sewing machine is supplied with a thread cutter. The sewing machin e i s then 2 mm behind its lower dead point.

Position 2

In the 2ne position, the thread take-up lever must be in its upper position.

Checking the positioning

After thread cutting, the sewing machine must stop in the 2nd position (thread take up lever in upper position).

–

Turn on main switch.

–

Lower the pedal briefly forwards.

–

Lower the pedal backwards completely and hold it lowered. The thread will be cut. The sewing machine will stop in the 2nd position (thread take-up lever in upper position).

–

Check whethe r the thread t ake-up lever st ands in its upper dead position.

–

Normally, here ends the checking process. Should it be necessary to correct the factory setting, proceed for programming the positions as follows.

6.10 Setting the positions

It is necessary to proceed to a new setting of the position transmitter after following operations:

–

Fitting the position transmitter when installing the special sewing machine

–

Removing the position transmitter

–

Replacing the position transmitter

–

Replacing th e complete dri ve controller

The digital position trans m i tter does not require any me chanical adjustments. It is only necessary to set the reference position when taking the machine into service for the first time.

The machine positions are sensed by steps (increments) by the position transmitter and they are shown by the display. One rotation of the handwheel corresponds to 512 steps. The change of the display is done by 2 steps. A change from one display value to the other corres ponds consequ ently to a rotation angle of about 1,4°.

The angle position of the positions 1 and 2 in respect top the reference position is defined by a certain number of increments.

Programming steps:

1. Calling up programming mode
