VIBROCONTROL 1500 Overview
- 6 - VC1500EN / C103845.002 / V 09 / 14.04.2015
2 Overview
The VIBROCONTROL 1500 is a 2-channel, microprocessor-controlled
measurement data acquisition, monitoring and diagnosis instrument.
Constant-current powered (CCS) acceleration sensors are used for the
vibration measurements.
In addition to the measurement of casing vibrations in the frequency ranges
from 1/3/10 Hz to 1,000 Hz, a rolling-element bearing condition variable is
also calculated for the assessment of rolling-element bearing condition.
For the measurement and monitoring of temperatures, of type PT-100
temperature sensors may also be applied in addition to the vibration sensors.
For operation of the instrument a power supply of 18 to 36 VDC is necessary.
The power consumption of the instrument amounts to approx. 6 W.

The standard equipment contains:
oTwo (2) relays with potential-free switch-over contacts for signaling event
messages. The relays are assigned to the set limit values.
oOne (1) OK relay with potential-free switch-over contacts for monitoring
of the power supply, the functions of the microprocessor system and the
connected sensors.
oTwo (2) analogue outputs proportional to the casing vibration.
oCAN-Bus interface for data transmission between the VIBROCONTROL
1500 and a super-ordinate computer.
All setting up tasks are carried out directly at the instrument by entry or
selection of parameter values. Setting up is also possible using the
VIBROCONTROL 1500 Control-Center-Software.
The connections for the power supply, measurement sensors, analogue and
contact outputs as well as the CAN-Bus interface are made through plug-in
terminal blocks.
2.2 Possible measurement and monitoring tasks

2.2.2 Measuring range limits
The measuring range can, according to the application, be adapted to the
machine or monitored plant by a wide range.
In the table below the measuring range limits (min. max.) are given
dependent upon the characteristic variable = effective (RMS) value of
vibration velocity.

For the selected measuring range, signals of 4 - 20 mA per sensor
proportional to the characteristic variable are available at the analogue
outputs.
2.2.3 Display value and bandwidth
Acquisition of the measured data is done by vibration acceleration sensors.

2.2.4 Signal detection
The output voltage of the measurement sensors is proportional to the
measured magnitude of the time signal (vibration acceleration).
The following signal detection step is carried out by the VIBROCONTROL
1500:
Calculation of the effective (RMS) value of vibration velocity from an
integration of the vibration acceleration signal.

2.3 General
Independently adjustable limit values are assigned to each measuring
channel for the casing vibrations, the rolling-element bearing condition and
the temperatures. The setting of the respective limit values is done in the unit
of the measurement channel.
Two values, which are adjustable over the entire measuring range, are
available for signaling a violation of the alarm limit settings. A limit value
violation is displayed at the VIBROCONTROL 1500 by means of LEDs and
the output of the violation respectively through potential-free relay contacts.
In order to prevent false alarms due to spurious, very short-term limit value
violations, a relay response lag time can be activated for each limit value of
the vibration.
The entry of the relay response lag time always take place in seconds units.
If a measured value exceeding the assigned limit value is sustained for
longer than the given response lag time, the appropriate event message is
activated.
If the current measured value falls below the limit value during the response
lag time, the event message "limit value violated" is deactivated and upon a
renewed limit value violation the response lag time count begins again.
2.4 Relay functions
VIBROCONTROL 1500 is equipped with a total of three (3) relays.
The status of these relays is signaled at the front panel by LED control
lamps. The relays are shared by both channels.
Note:
Short the reset contacts only for a short notice.
Caution
Voltages of a dangerous level may exist at the relay contacts at any
time!
LIM 1 relay
If the current measured value exceeds the set limit value for the RMS value
of vibration velocity L1v for longer than the period of the adjusted response
lag time T1, the LIM1 relay is activated (closed).
The same is valid - however without consideration of a response lag time -
during a violation of the limit value of the bearing condition L1BC and a
violation of the limit value of temperature L1temp (with the deployment of a
vibration sensor with PT-100 sensor or temperature sensor PT-100).
The LIM 1 relay is not self-latching and is immediately deactivated
(opened) if all L1v, L1BC or L1temp limit value is no longer violated.

LIM 2 relay
If the current measured value violates the set limit value for the RMS value of
vibration velocity L2v for longer than the period of the adjusted response lag
time T2, the LIM2 relay is activated (closed).
The same is valid - however without consideration of a response lag time -
during a violation of the limit value of the bearing condition L2BC and a
violation of the limit value of temperature L2temp (with the deployment of a
vibration sensor with PT-100 sensor or temperature sensor PT-100).
The LIM 2 relay is self-latching. To reset this condition a reset of the relay
or an instrument reset must be carried out.
OK relay
Monitoring of the power supply, the functions of the microprocessor system
and the connected sensors is done by an OK-monitoring function. The
display of an existing OK fault is by means of an LED; the output of this
signal is by means of a set of potential-free switch-over contacts.
With an error-free operation the green LED at the instrument front panel
lights up (signaling operational readiness) and the contacts of the OK relay
are closed.
In case of a fault the LED is extinguished and the OK relay will be
deactivated.
This OK relay is active during error-free operation (closed, terminals 33 and
34 are connected). When a fault occurs these relay contacts open. This relay
is self-latching. To reactivate this, a reset of the relay or the instrument is
necessary.
Instrument Reset
Simultaneously pushing both of the buttons and ENTER/MENU for a
period of at least 3 seconds effects a reset and a restart of the instrument.
Reset of the self-latching relay
A reset of the active (closed) condition of the self-latching relays OK and
LIM2 is possible at the RESET input by connecting terminals 25 (RST REL2)
and 26 (GND). This reset simultaneously also deletes all error messages.
Note:
Short the reset contacts only for a short notice.
