If the VIBROCONTROL 1800 Monitors develops a fault, switch it off and secure it against
unintended use.
General:
Please carefully read the operating instructions prior to set-up of the device. Make sure that your
VIBROCONTROL 18xx device is suitable for your application without any restrictions.
Improper use:
Any improper or non-intended use may lead to malfunctions of the VIBROCONTROL 18xx device or to
unwanted effects in your application. If the VIBROCONTROL 18xx is used in a way not described in the
relevant user manuals, function and protection may be impaired and serious personal damage, death or
serious, irreversible injuries may result.
Installation and operation:
Installation, electrical connection, set-up, operation and maintenance of your VIBROCONTROL 18xx device(s)
must only be carried out by qualified/trained personnel (electrician) authorized by the machine operator in
accordance with local- and national regulations for the installation of electrical equipment.
Changing the setup parameters:
Before applying a new set of setup parameters to the VIBROCONTROL 18xx device, please make sure that
doing so cannot cause any damage to persons and/or machinery.
Connecting the sensor(s):
Please make sure to meet the safe extra-low voltage (SELV) criteria when any sensors are connected to the
VIBROCONTROL 18xx device so that no dangerous contact voltages are applied to the sensor and/or
transferred to the device. The sensor and the power supply of the VIBROCONTROL 18xx device are not
galvanic isolated.
Electromagnetic compatibility (EMC)
The VC-18xx complies with the relevant
requirements of the Electromagnetic
Compatibility Directive 2014/30 / EU. The EMC
has been tested according to EN 61326-1, with
the reduction of the requirement for static
electricity (ESD).
When handling the VC-18xx, attention must be
paid to protective measures against electrostatic
discharge. This applies in particular to the area
of ventilation slots.
Electrostatic discharges in this area can destroy the device.

EN Pre-Release
Sensor cable mounting:
To prevent negative effects on the functioning of the VIBROCONTROL 18xx device caused by noise voltages,
please lay shielded sensor cables and load cables separately.
Cable break, cable short and sensor overload:
For a detailed description of how a VIBROCONTROL 18xx device reacts to a shortening/breakage of the
sensor cable or an overload of the sensor signal, please read section 6.16 of this manual.
Ingress protection:
The VIBROCONTROL 18xx has an ingress protection of IP20. The VIBROCONTROL 18xx device must be
mounted in a control cabinet with an ingress protection of at least IP54. The control cabinet should be installed
in accordance with local- and national rules and regulations.
Mounting:
Mount the VIBROCONTROL 18xx device on a 35 mm DIN rail inside the control cabinet. Mount the device
vertically but make sure to leave enough space between the unit and the top and/or bottom of the control
cabinet. Only this way the air circulation will be sufficient to avoid excessive heating of the device.
Connecting to a power supply:
The VIBROCONTROL 18xx device has a voltage tolerance of +24 VDC ±5 %
Before connecting the VIBROCONTROL 18xx device to a +24 VDC supply voltage, please make sure that all
terminal blocks are completely inserted.
The external +24 VDC supply voltage must be generated and supplied according to the SELV requirements.
Protect the +24 VDC supply voltage externally with max. 2A.The ground (GND) of the DC supply is directly
connected with the ground (GND) of the sensor supply, if any. The SELV criteria must therefore be met for the
DC supply (safety extra-low voltage, circuit electrically isolated from other circuits, not grounded). If the DC
circuit is to be grounded (e.g. due to national regulations), the protective-extra-low-voltage (PELV) criteria must
be adhered to (SELV with circuit galvanic isolated from other circuits).
Maintenance:
If used correctly no maintenance and repair measures are necessary. Only the manufacturer is allowed to
repair the unit.

5.2 Features of VIBROCONTROL 1850
The VIBROCONTROL 1850 Vibration Monitor is a device with four sensor input channels, each having two
independent bands (Band 1 and Band 2) with the following specifications:
Band 1 and Band 2:
 Full scale in True RMS, Peak or Peak-to-Peak values of the momentary vibration parameters
acceleration (m/s2), velocity (mm/s) or displacement (µm);
 Many band-pass filters within the ranges:
Band 1
0.1 to 1500.0 Hz or 5.0 to 11500.0 Hz; 10 Hz – 1000 Hz
Band 2
2 kHz – 10 kHz
 Alert and Danger alarm limits can be configured.
Default setup
Alert is 7.1 mm/s
Danger 11.0 mm/s.
Band 2 (only):
 Two separate envelope detectors. Each envelope detector has its own band-pass filter. Each
envelop analyser has its own Alert and Danger alarms.
 Crest factor detector with Alert and Danger alarms
 Kurtosis detector with Alert and Danger alarms
General for All VIBROCONTROL VC-18xx:
 Each vibration parameter may have an individual alert and/or danger alarm trigger level
assigned. If an alert and/or danger alarm is activated, the associated channel LED(s) at the front
of the enclosure will illuminate:
Green = No alarm, Yellow = Alert alarm and Red = Danger alarm
 The Alert and/or Danger alarms can be configured as “Low Level” or “High Level” alarms
 The Alert and/or Danger alarms can be latched individually.
 Four independent configurable outputs (terminals #9, #10, #11 and #12) that can be assigned to
any Alert or Danger alarm. Each of the outputs may have any (but only one at the time) of the
following functions:
~ Solid-state relay. When activated the relay will “break”, the corresponding enabled alarm
relay(s) will become activated and thereby inform the user, e.g. via a connected rotor light,
beeper, PLC or by directly shutting down the machine.
~ Analog dc current output : 0-20 mA or 4-20 mA; The default is 4-20 mA
~ Analog dc voltage output : 0-10 V or 2-10 V
 An internal watchdog continuously monitors the functionality of the complete monitor. When a
non-critical system failure is detected, the „OK“ LED at the front of the enclosure lights Red.
In case of the occurrence of a critical system failure, the same LED flash Red instead. Using two
mechanical relays in series for the same event adds redundancy to the system failure output and
thus considerable increases the reliability that a system failure alarm will be detected.

Pre-Release
 Possibility to start a complete self-test of the vibration monitor by connecting the “Self-Test”
terminal #8 to ground. A flashing Yellow „OK“ LED at the front of the enclosure indicates an
ongoing self-test.
 Possibility to inhibit (all) alarms by assigning the “Alarm Inhibit” digital I/O terminal #5 on the
enclosure to ground
 A Process input (terminal #21) can be used to analyse an analog current (0-20 mA) or voltage
(0-10 VDC) input signal.
 A tachometer input (terminal #24).
The VIBROCONTROL 18xx Vibration Monitor is provided with a RS-485 and an USB interface, which allow it to
to connect it to a PLC or to be configured from a PC.
Using a VIBROCONTROL 1803 Ethernet-Bridge enables remote communication via a LAN cable.

VIBROCONTROL 18xx EN
6 Setup and Operation of VIBROCONTROL 18xx
6.1 General
The setting of the measuring parameters of the VIBROCONTROL 18xx can be carried out with Compact Setup
Software:
 It is possible to change one or more setup parameter. The change of VIBROCONTROL 18xx
setup parameters can only be carried out for one device at the time.
The measuring parameter setup for channels with an accelerometer (CCS) VIBROCONTROL 1850 or a
velocity sensor VIBROCONTROL 1860 is very much similar.
6.2 View “Monitor”
In the Compact Setup Software “Monitor” page it is possible to see those features/functions that are available
for use.

Page 20 of 84 █© Brüel & Kjaer Vibro ●July 2018 ●C106834.002 / V02
Technical alterations reserved!
EN Pre-Release
6.3 Self-Test
The VIBROCONTROL 18xx includes a “Self-Test” function that can be activated externally by connecting a
ground (GND) signal to terminal #8 on the enclosure. Alternatively the self-test can be activated using the
Compact Commander Software.
Only individual functions/features can be addressed during a self-test. But there are NO consequences, i.e. no
alarms will be triggered if a certain vibration level set during self-test exceeds an alarm trigger level. If an alarm
must be triggered during self-test the alarm in question must be marked. The behaviour of outputs during a self-
test must also be specified separately.
Thus, the user will have to specify/set the following in connection with a self-test:
 The measurement result scalar level for each vibration parameter in its own units, e.g. mm/s.
 The status of alarms during a self-test.
 All four outputs, either as a status of relays or a certain scalar level of
○ dc current (mA) or
○ dc voltage (V).
 The Process Input must be specified in detail, i.e. signal scalar levels and alarms.
For the duration of thy self-test the „OK“ LED will flash Yellow.
