Rotoclear C Basic Bedienungsanleitung Seite 51

OPERATING MANUAL
When laying the data cable, ensure that no inter-
fering signals from neighboring power cables can
disrupt the transmission. We recommend to use
the data cable provided.
Please ensure the dryness and cleanliness as
well as the correct configuration of the sealing air
supplied. Pay attention to the requirements for
the sealing air which are indicated in the chapter
"Technical data" in the appendix.
The camera head is equipped with a pressure
sensor. It helps with the correct configuration of
the sealing air and monitors it constantly. An in-
correct configuration or damage to the system is
detected and a warning displayed in the user in-
terface.
The pressure sensor measures the absolute
pressure. This means that the ambient pressure is
also measured. Without sealing air applied, a pres-
sure of approx. 1,000 mbar is already displayed.
The exact measured value depends, among other
things, on the region and the weather. The sealing
air only has to ensure the difference between the
ambient pressure and the specified pressure (see
chapter "Technical data").
It is not recommendable to orientate the
camera head upwards due to the risk of fluids en-
tering the labyrinth sealing in the case of insuffi-
cient air purge or fluids occurring while the ma-
chine is switched off.
If the rotor disk is damaged, please refer to the
chapter "Changing the rotor". Leaks due to con-
taminated or insufficient sealing air will impair the
sight and the functioning of Rotoclear C Basic. If
necessary, pre-treat the sealing air using a service
unit with a multi-stage filter system.
Both the camera head and the HDMI unit
have a connection for grounding (Fig. 2-H resp.
Fig. 4-A) Connect both to the grounding conduc-
tor using a grounding cable. Make absolutely sure
that all devices are connected to the same pro-
tective earth conductor.
Signal amplifier (accessory)
The length of the data cable connecting the cam-
era head and the control computer is limited to
20 m (see chapter "Technical data" in the appen-
dix). It is possible to extend this length with the
Rotoclear C-Extender signal amplifier (Fig. 5-A).
Up to two signal amplifiers per camera head can
be used in the supply line. Each of these devices
adds the maximum possible data cable length
without signal amplifier: with one signal amplifier
the maximum possible length is 2 × 20 m, with two
signal amplifiers the maximum possible length is
3 × 20 m.
