X Undock the WPC4 from the SIPLACE machine and move it to a suitable position for service work.

X Switch the WPC4 off at the main switch.

X Unplug from the power supply and secure the WPC4 to prevent unauthorized reactivation.

X Loosely fix the motor support and drive motor

into the installation position, with the 2

fastening screws (3).

X Set the final belt tension. To do this, tension

the drive toothed belt at the tensioning device,

with the help of the tensioning screw (2). This

moves the motor support accordingly in the

slots.

 Setting value: Set the belt tension to

260 Hz. +/- 10 Hz.

X Tighten the 2 fastening screws (2) on the

motor support, check the belt tension and

Removal/installation

X Move the catch feed axis with the toothed belt

into a suitable position for service work (at the

front, in the transfer area).

X Loosen the two fastening screws (1) sealed

with locking varnish, at the tensioning device

with the deflection pulley (3).

X Loosen (do not remove) the tensioning

screw (2) - sealed with locking varnish - on the

tensioning device. This relaxes the toothed

belt.

X Loosen the 4 fastening screws (4) on the catch

unit (5). The two ends of the toothed belt are

fixed to this.

X Carefully remove the catch unit (5). This

toothed belt is now loose.

X Note how the toothed belt is run, so that you

can fit it again correctly later on. Pull the

toothed belt over the two deflection pulleys

(back and front) and out of the WPC4.

X Remove the tensioning device and deflection

pulley (3), so that you can feed in the new

toothed belt more easily. To do this, loosen the

two fastening screws (1).

X Insert the toothed belt into the WPC4 at the

transfer position and run it from the tensioning

device (1) to the deflection pulley (4). The

toothed belt should exit below the bottom

deflection pulley (3).

X Place the end of the toothed belt around the

back deflection pulley (3) and insert into the

clamping unit (5).

X Place the other end of the toothed belt around

the deflection pulley of the tensioning unit (2)

and run as far as the clamping unit (5).

X Fit the tensioning device with deflection pulley

and fix into place with the two fastening

screws.
