Electrical System 3.2.2 Measuring Voltages at the Power Supply Unit

40 Service Manual SIPLACE SX1/SX2/DX1/DX2 FS02

Preparation

► Reconnect the machine to the power supply.

► Switch the placement machine on again at the main switch and start it up.

Performing measurements

► Measure the required voltages.

CAUTION

Take care not to damage the supply lines!

Make sure that the main power cable and supply cables in the machine are not trapped and

that the insulation is not damaged.

► End all placement operations on the machine.

► Switch the machine off at the main switch (2).

► Disconnect the machine from the main power supply.

► Open the lock (1) on the power supply cover (3).

► Pull the power supply out towards the front.

DANGER

Touch voltages

There may be dangerous touch voltages in the vicinity of the open power supply!

NOTICE

Voltages

Please refer to the relevant circuit diagram for your machine for details of the various voltages.

Checking/setting

► Remove the mesh cover on the boards. To do this, loosen the four screws on the side of the cover.

► Check the jumper arrangement and correct if necessary.

Take note of the position of jumper J1 (see "5.1.5 Inrush Current Limitation Board Transformer (A1)

[03066830-xx]" [ ➙ 310]).

► Fit the protective grid back into place.

DANGER

Voltages

There is a risk of dangerous touch voltages and short circuits occurring in power supplies which

have been made accessible and are connected for measurement purposes or bridge circuit

control.

Nonobservance of these safety instructions may cause injury to personnel and damage to the

machine!

Measurements may only be performed by specially trained service technicians, with appropri-

ate qualifications and expertise.

► Observe the instructions in section Safety Instructions for the Power Supply (Without

SMPS).

1. Board A1 for the inrush current limitation board of the

transformer

X1, X2, X3: plug-in jumpers to configure the inrush cur-

rent limitation

The inrush current limitation board must be set to 400 V,

irrespective of the supply voltage. This is performed with

the help of plug-in jumpers on the inrush current limitation

board (1).

► Check the jumper assignments and correct these,

where necessary.
