(strand center )
► The deflection pulleys, around which the conveyor
toothed belt is run at approximately 180°, are fas-
tened at a slot. The tension of the conveyor toothed
belt can be adjusted by moving this deflection pulley.
► Position the measuring point of the belt tension de-
vice at the strand center (i.e. the longest distance be-
tween the two deflection pulleys) of the conveyor
toothed belt.
► Set the tension of the drive toothed belt according to
the following values.
NOTICE
The tension frequencies per area may vary according to the different belt guides. The belt ten-
sion always remains the same.

The belt is tensioned by means of cams on the tensioning
rollers. The tensioning rollers are located on the left and
right of the motor.

1. Loosen the cam shaft on the tensioning roller and set
the belt tension.
NOTICE
The modular conveyor uses different belt lengths. The differing belt tensions between the con-
veyor lanes are due to the different arrangement of hexagonal shafts and deflection pulleys.

Measuring points (arrows) and measuring values for con-
veyor belt tensions:
Single conveyor or dual conveyor lane 1

6.7.2 Setting the Fixed Conveyor Side (single and dual conveyor)
Setting the Fixed Conveyor Side (single and dual conveyor)
Two requirements for changing the fixed conveyor sides:
▪ Extra wide conveyor – moves the fixed conveyor side 34 mm outwards.
▪ Widened conveyor – moves the sides of the 2nd conveyor to the limit switch.
Single conveyor control mode (D-series up to 380 mm/HF, X lines up to 450 mm)
6.7.2.1
6.7.2.1 Widening the Conveyor (Flexible Dual Conveyor for Single Conveyor Mode)
Widening the Conveyor (Flexible Dual Conveyor for Single Conveyor Mode)
► In the SITEST conveyor menu Options and Configurations select Change Widening of Conveyor to
widen the conveyor.
► The conveyor rails of conveyor 2 (right side fixed (track 1 left side fix)) are moved to the limits.
► The SITEST SW ask for connecting the lifting tables.
Widening the board conveyor (from its standard width) allows you to use boards up to 380 mm wide.
Widening the board conveyor from the mode "Widened" to the mode "Extra Wide" allows you to place
boards up to a width of 430 mm.
SITEST "Set fixed conveyor side"
NOTICE! The menu Referenzposition feste
Wange is protected with the Siemens Service password.
▪ The fixed conveyor side can be set in SITEST if re-
quired.
▪ If the position taught for the fixed conveyor side is
saved, these values will be used for the function
Move all conveyor edges in standard position.
The default values will be overwritten and will need to
be retaught.
▪ If these dimensions are incorrectly set on the single
or dual conveyor, the PCB reference corner may be
moved, leading to fiducial errors during placement.
NOTICE
In the SR/MC station SW, the fixed conveyor side of all lanes can be adjusted in the conveyor
firmware (flexible). However, this may only be set with the SITEST software.
NOTICE
In the D series machines, you need to remove the clamping rings on the fixed conveyor side in
advance.
