RHEINTACHO Stroboscope Control Unit Bedienungsanleitung Seite 2

Stroboscope Control Unit provides you with a variety of options
for controlling and setting your high-performance stationary
stroboscope.
These operating instructions are an essential part of the ins-
trument. They must be kept close at hand and passed on to
subsequent users. If there is something you don't understand,
consult your supplier.
The manufacturer reserves the right to continue development of
this instrument without necessarily documenting this in every
case. Your supplier will be happy to update you on the current
applicability of these operating instructions.
1. Use for the intended purpose
This instrument is intended for the control of stroboscopes. It is ge-
nerally possible to use this instrument with stroboscopes of other
manufacturers, though with optional accessories (adapters).
Stroboscope Control Unit must always be operated in conformity with
these operating instructions. The instrument must not be modified in
any way. The manufacturer will accept no liability for damage caused
through improper use or use for any purpose other than that intended.
Such use would invalidate any claims made under the warranty.
2. Safety precautions
 WARNING Moving objects appear in stroboscopic light as either im-
mobile or in slow motion. Do not touch the objects.
WARNING The instrument must not be used in areas exposed to the

risk of explosion.
 WARNING Store the instrument in dry conditions. It must not be ex-
posed to dripping or spraying water. Never place objects containing
liquids (e.g. vases) on this instrument.
 WARNING Stroboscopic light can trigger epileptic attacks in suscep-
tible persons.
ATTENTION Repairs to this instrument must be carried out exclusi-
vely by the manufacturer or the supplier.
ATTENTION The electronic components of the instrument contain
materials which are harmful to the environment. They must be dispo-
sed of in accordance with the environmental policies in force in the
country of use.
3. Assembly and connection
The power can be supplied either via the installation under observa-
tion or the stroboscope's own power supply. Alternatively, power can
be supplied via a power supply unit (optional).
The function of the stroboscope control unit is to control a strobo-
scope. In addition, it can be used to influence an incoming trigger
signal from an external system. This device has two jacks. Power can
be supplied via either of these jacks. The jack for trigger input from an
external system or sensor is labelled IN. The jack for trigger output to
a stroboscope is labelled OUT. The position of the jacks is indicated
in (Fig. 1). The wiring of the connectors is shown in (Fig. 2).

ATTENTION Please follow the wiring assignments as shown on the
attached wiring diagram – see Fig. 2.
The trigger input is voltage-free. The voltage-free contracts are suita-
ble for PNP and NPN signals. This instrument comes equipped with
a cable and plug that match these input jacks.
RECOMMENDATION To wire the trigger signal, use a sheathed

cable.
Typical wiring options:
Please see Figs. 3-6 for examples of wiring options. Please
note that you need optional accessories for the examples (such as
an stationary stroboscope, power supply unit or sensor).
a) Trigger signal from this instrument. Power supply from the
power supply unit (optional) (Fig. 3)
b) Trigger signal and power supply from external installation
(Fig. 4)
c) Trigger signal from this instrument. Power supply from the
stroboscope (optional) (Fig. 5)
d) Trigger signal from sensor (optional), power supply for this
instrument from stroboscope (optional). Sensor power supply
via this instrument (Fig. 6)
The power can be supplied either via the instrument's power supply
unit (available as an option) or via the installation under observati-
on.

5. Special Functions – Notes on Usage
PULS µs / PULS deg
Duration of output signal pulse (in microseconds). Use this function
to set the output signal pulse duration. This may be necessary, for
example, if the default setted short pulse duration is inadequate for
control of the connected stroboscope. You can make this setting eit-
her in absolute terms (microseconds) or in relative terms (degrees).
DELAY ms
Setting the delay time between input and output signal (in millise-
conds). Use this value to set a fixed delay time between input signal
and output signal.
Example: The trigger signal is generated at a position in front of the
desired observation point (= stroboscope flash position). In this situa-
tion, the connected stroboscope would regularly flash too early. Use
DELAY ms to set the value in order to delay the output signal.
PHASE deg
Setting the phase shift (in degrees, relative to frequency) between
input and output signal. Use this value to set a fixed angle between
input signal and output signal.
Example: The trigger signal is generated at a position in front of the
desired observation point (= stroboscope flash position). In this si-
tuation, the connected stroboscope would regularly flash too early.
Use PHASE deg to set the delay to make the stroboscope flash at a
position which is shifted by the set angle. This setting is independent
of the current rotational speed. In this way, it is possible to trigger a
stroboscope flash even if the rotational speed is fluctuating or when
starting up the installation.
DIV (Pulse Divider)
This function is only active in the presence of an external trigger sig-
nal. Use the pulse divider to set a value x. The external trigger signal
is then divided by this value.
Example: An external trigger (e.g. rotational speed sensor) monito-
ring a gear wheel delivers a signal for each tooth. If the DIV value =
10, only every 10th input pulse is delivered as an output signal to a
connected stroboscope.
OPT
Trigger signal edge selection. 0 = positive edge, 1 = negative edge.
Use this option to define the polarity of the trigger signal.
