Preselecting regu-
lator „Pressure
load delay time to
start paving“
It sets the delay time of the prestressed start of the screed.
A
The delay time must be set depending on the working
speed.
- High working speed - short delay time
- Low working speed - longer delay time
25
Auger modes of
operation on the
right/left sides
A auto: with the drive lever turned on and using the ma-
terial limit switch at the auger for continuous
regulation
B stop: turned off
C manual: turned on, transport direction inward/outward.
(The direction set by switch (26))
A
In position (C), when the switch (26) is turned on, the
half-augers work continuously (full transport capacity,
without automatic material regulation).
If you wish to switch the auger with automatically with the me-
chanical limit switch and the (
o
) ultrasonic sensor, both
switches must be in „auto“ position.
26
Adjustment of au-
ger beams
on the LH/RH
sides (
o
)
In case of hydraulically adjustable auger beams, this is the
way to change the height of the auger.
- The height can be read on the scale on the LH/RH sides of
the auger beam support.
Basic rule: Laying thi 5 cm (2 inches) = auger
beam height.
m
Operate both switches at the same time, or else the
auger beams will go slant.
27
Conveying direc-
tion of the auger. For setting / switching over the transport direction of the two
auger halves in „manual“ mode.
28
Screed extension/
retraction (
o
)
With this the extendable parts of the Vario screeds can be
hydraulically extended or retracted.
A
In the EU countries this is permitted with the remote
control switch only.
29
Opening/closing of
the feeding hopper
top: Opening of hopper
middle: has no function
bottom: Opening of hopper
Separate actuation (
o
):
Necessary when laying in a tight place on one side or when
filling from the truck is hindered.
