1Preface
Please read this instruction manual
entirely and
carefully before installa-
tion and start
-up. Please observe all
warnings and advice, both for your
own safety and for general plant saf
e-
ty. If the device is not used in accor
d-
ance with th
is instruction manual,
then the intended protection can be
impaired.
2Safety instructions and Warnings
Please use the device only if it is in
perfect technical condition
. It should
be used only for its intended purpose.
Please bear in mind safety aspe
cts
and potential dangers and adhere to
the operating instructions at all times.
Defective or damaged devices should
be
disconnected from the mains im-
mediately and
taken out of operation.
The device shall not be opened. Use
the repair service of the ma
nufactur-
er
.
Only connect the device to the elec-
tri
city networks provided to that pur-
pose
.
The safety of the system in which the
device is integrated is the responsibi
l-
ity of the
installer.
Disconnect all electricity networks
prior to any installation
or mainte-
nance work
.
Use exclusively cables approved in
your country and designed for your
temperature and power ranges.
Installation and service work shall be
carried out exclusively by qualified
personnel.
The device must compulsorily be pro-
tected
with approved external fuses.
The value of these fuses can be found
in the technical information.
This symbol is used on the device to
remind of the existence of dangers,
which are referred to in this manual
.
2.1 Indended use
The panel mounting display VA3K01 detects
and measures pulses, times and frequen-
cies up to max. 60 kHz and offers a wide va-
riety of different operating modes. At the
same time, the preset counter processes
programmed presets. Use for any purpose
over and beyond this will be deemed as not
in accordance with its intended purpose and
thus not complying with the requirements.
The application area for this device lies in
industrial processes and controls, in the
fields of manufacturing lines for the metal,
wood, plastics, paper, glass, textile and oth-
er like industries. Over-voltages at the ter-
minals of the device must be kept within the
limits of Over-voltage Category II.
The device must only be operated when
mounted in a panel in the correct way and in
accordance with the section “Technical Da-
ta”.
The device is not suitable for use in hazard-
ous areas and for areas excluded in
EN 61010 Part 1. If the device is used to
monitor machines or processes in which, in
the event of a failure of the device or an er-
ror made by the operator, there might be
the risk of damaging the machine or causing
an accident to the operators, then it is your
responsibility to take the appropriate safety
measures.
The device has been designed for indoor op-
eration. It may nevertheless be used out-
doors, provided the technical data is ad-
hered to. In this case, take care to provide
suitable UV protection.

2.2 Mounting in a control panel
CAUTION
Mount the device away from heat
sources and avoid direct contact
with corrosive liquids, hot steam
or
similar.
Provide a free space of 10mm all
around the device for its ventil
a-
tion.
The device should be mounted so
that the terminals are out of the
reach of the operator and cannot
be touched by him. When moun
t-
ing the device, consider the fact
that only
the front side is classi-
fied as accessible for the operator.
Mounting instructions
1. Remove the mounting clip from the de-
vice.
2.
Insert the device from the front into the
panel cut-out, ensuring the front-panel
gasket is correctly seated.
3.
Slide the fixing clip from the rear onto
the housing, until the spring clamps are
under tension and the upper and lower
latching lugs have snapped into place.
In case of proper installation, IP65 can
be reached on the front side
.
2.3 Electrical Installation
DANGER
The device must be disconnected
from
any power supply prior to
any installation or maintenance
work. Make sure that no more
voltages
liable to cause an elec-
trocution
are present.
AC
-powered devices must only be
connected to the low
-voltage net-
work via a switc
h or circuit break-
er
installed close to the de
vice and
marked as their disconnecting d
e-
vice.
DANGER
Installation or maintenance work
must only be carried out by qual
i-
fied personnel
and in compliance
with the applicable national and
international s
tandards.
Take care to separate all extra
-
low voltages entering or exiting
the device from hazardous electr
i-
cal conductors by means of a do
u-
ble or reinforced insulation (SELV
circuits).
DANGER
The device must be protected ex-
ternally for its proper op
eration.
Information about the prescribed
fuses can be fou
nd under “Tech-
nical Data”.
The relay outputs
are not protect-
ed internally in the device
.
Without
suitable protection of the relay
outputs, undesired heat develo
p-
ment or even fire may occur
. The
r
elay outputs must be protected
externally by the manufa
cturer of
the plant
. It must also be made
sure that, even in case of a ma
l-
function, the values stated in the
technical data are under no ci
r-
cumstances exceeded
.
During installation, make sure that the
supply voltage and the wiring of the out-
put contacts are both fed from the same
mains phase, in order not to exceed the
maximum permitted voltage of 250V
The cables and their insulation must be
designed for the planned temperature
and voltage ranges. Regarding the type
of the cables, adhere to the applicable
standards of the country and of the
plant. The cross sections allowed for the
screw terminals can be found in the
technical data.
Before starting the device, check the
cables for proper wiring and tightening.
The screws of unused screw terminals
must be screwed to the stop, so that
they cannot loosen and get lost.

Safety instructions and Warnings VA3K01

The device has been designed for over-
voltage category II. If higher transient
voltages cannot be excluded, additional
protection measures must be taken in
order to limit the overvoltage to the val-
ues of CAT II.
Advice on noise immunity
All connections are protected against exter-
nal sources of interference. The installation
location should be chosen so that inductive
or capacitive interference does not affect
the device or its connecting lines!
Interference (e.g. from switch-mode power
supplies, motors, clocked controllers or
contactors) can be reduced by means of ap-
propriate cable routing and wiring.
Measures to be taken:
Use only shielded cable and control
lines. Connect shield at both ends.
The conductor cross-section of the ca-
bles should be a minimum of 0.14 mm².
The shield connection to the equipoten-
tial bonding should be as short as pos-
sible and with a contact area as large as
possible (low-impedance).
Only connect the shields to the control
panel, if the latter is also earthed.
Install the device as far away as possi-
ble from noise-containing cables.
Avoid routing signal or control cables
parallel to power lines.
2.4 Cleaning and maintenance
The front side of the unit should only be
cleaned using a soft damp (water!) cloth.
Cleaning of the embedded rear side is not
planned and is the responsibility of the ser-
vice personnel or of the installer.
In normal operation, this device is mainte-
nance-free. Should the device nevertheless
not operate properly, it must be sent back to
the manufacturer or to the supplier. Open-
ing and repairing the device by the user is
not allowed and can adversely affect the
original protection level.
