Sensor cable mounting:
To prevent negative effects on the functioning of the VIBROCONTROL 18xx caused by noise
voltages, please lay shielded sensor cables and power supply separately.
Cable break, cable short-circuit and sensor overload:
For a detailed description of how a VIBROCONTROL 18xx device reacts to a breakage of the
sensor cable or an overload of the sensor signal, please read section 6.17 of this manual.
Ingress protection (IP):
The VIBROCONTROL 18xx has an ingress protection of IP20. The VIBROCONTROL 18xx 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 on a 35-mm DIN-rail inside the control cabinet. Mount the device
vertically. Make certain to leave enough space between the device and the top and/or bottom of the
control cabinet. Only in this way will the air circulation be sufficient to avoid excessive heating of
the device.
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

Connecting to a power supply:
The VIBROCONTROL 18xx has a voltage tolerance of +24 V DC ±5 %.
Before connecting the VIBROCONTROL 18xx to a +24 V DC supply voltage, please make sure
that all terminal blocks are completely inserted. The external +24 V DC supply voltage must be
generated and supplied according to the SELV requirements with power limiting.
Protect the +24 V DC 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 electrically
isolated from other circuits).
Maintenance:
If used correctly, no maintenance and repair measures are necessary.
Only the manufacturer is allowed to repair the unit.
ATTENTION!
The power supply unit may only be supplied with power via a disconnecting device (switch or circuit
breaker)!
The disconnecting device must meet the requirements of IEC 6094-7 and
IEC 60947-3 and be suitable for the application.

The VIBROCONTROL 1850 vibration monitor has four inputs for accelerometers.
5.2 Functions of VIBROCONTROL 1850
The VIBROCONTROL 1850 vibration monitor provides two independent frequency bands (band 1
and band 2) for each vibration measurement channel:
Band 1 and band 2:
•Full scale in True RMS, Peak or Peak-to-Peak values of the momentary vibration parameters
acceleration (m/s2), speed (mm/s) or displacement (µm);
- Band-pass filters for selection 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 alarm and Danger alarm limits can be configured.
Default setting:
Alert alarm is 7.1 mm/s; Danger alarm is 11.0 mm/s.
Band 2 only:
•Two separate envelope detectors. Each envelope detector has its own band-pass filter. Each
envelop analyzer 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:
•An individual Alert or Danger alarm can be assigned to each vibration parameter. If an Alert or
Danger alarm occurs, the corresponding LED is lit:
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 set to latching or non-latching. This setting of an alarm
can only be changed by the software
(Compact Setup or Compact Analyzer).
•Four independent configurable outputs (terminals # 9, # 10, # 11 and # 12), can be defined as
relay outputs (for Alert or Danger alarm) or as analog outputs. Each of the outputs can have any
(or just any one) of the following functions:
~ Solid-state relay. When the relay is enabled, a message (warning light, signal tone) can be sent
or the machine can be shut down.
~ Analog DC current output: 0-20 mA or 4-20 mA;
The default value is 4-20 mA
~ Analog DC voltage output: 0-10 V or 2-10 V

•System status/OK status
An internal watchdog monitors the functional capability of the complete monitor continuously.
If a non-critical system error occurs, the LED on the front is lit Red.
If a critical system error occurs, the Red LED flashes.
Using two mechanical relays in series for the same event adds redundancy to the system error
output and thus considerably increases the reliability that a system failure alarm will be detected.
○A complete self-test of the vibration monitor can be started by connecting the "Self-
Test" terminal #8 to ground.
A flashing Yellow "Status" LED on the front of the enclosure indicates an ongoing
self-test.
○"Alarm Inhibit": Terminal #5 (against GND) suppresses all alarms.
○A process input (terminal #21) can be used to connect an analog current (0-20 mA)
input signal or voltage (0-10 VDC) input signal.
○A tachometer connection (terminal #24)
The VIBROCONTROL 18xx vibration monitor has an RS-485 and a USB interface.
The USB interface can be used on a PC for configuration and data acquisition.
Using the VIBROCONTROL 1803/04 Ethernet Bridge, the VIBROCONTROL 18xx can be
coconnected to a LAN network via the RS-485 interface.
