Adash VIBRAMON 1 User manual

VIBRAMON 1
User Manual
Proper Mounting of the Vibramon 1 is very important. It must be mounted horizontally or vertically, aligned
with one of the axis marked on the Vibramon 1 and firmly fixed. The axis must also be aligned with one of
the major axis of the machine. For e.g. Shaft of the Motor.
Vibramon 1 measures the RMS Overall Velocity in mm/sec. The vibration limits can be set according to
three standards. ISO 10816 or Adash or Custom Limit can be set in mm/sec. There is a delay before a
failure is recognized. This delay is set to 10 or 20 seconds by default. But it can be changed to the
required value. The vibration level has to exceed the limit set, continuously for the amount of delay, for
failure to be recognized. Once failure is detected, the relay changes state and is latched. This can be
reset with a NO contact of a momentary push button wired to RESET terminals of the Vibramon 1 and
pressing the push button briefly. Alternately the failure relay can be reset by pressing the RESET button
on the Vibrmon 1 for 3 seconds. For reset to take place the vibration level must have reduced to the safe
level for atleast the same duration which has been set for a failure to be recognized and remain below this
level. The relay operates in failsafe mode. The relay is normally in ON condition. When a failure occurs,
the relay turns OFF. In case of a power supply failure, the relay will be in failure mode.
The different Parameters which can be set for the Vibramon 1 are as follows:
1. Alarm Level - AL1 (for Custom Setting only) in mm/sec 0.00 to 99.99 mm/sec. The warning level in
such a case is 50% of the limit set.
2. Hysteresis Level - HYS1 - for warning LED indicator. It is the level, below the limit level, below which
the warning LED indicator is switched off.
3. RPM of the Drive Motor. By default this is set to 1500 RPM. This is for Adash based limits, which are
solely based on the RPM of the motor and not based on the power rating of the motor.
4. Class of machine - CLAS. By default this is set to 1. This is used by the ISO 10816 standard for vibra-
tion level. ISO 10816 defines vibration warning and failure level based on 4 classes as follows:
CLAS = 1 - motors less than 15 KW
CLAS = 2 - motors from 15 KW to 75 KW
CLAS = 3 - motors >75 KW with rigid mounting
CLAS = 4 - motors >75 KW with flexible mounting
5. Vibration Standard - VSTD - Three different standards can be used for setting the vibration limits. The
different options are as follows:
VSTD = 1 : ISO 10816-1 or ISO 2372 (old).

The lower boundary value and the upper boundary value of the pink area in the above image
will be used for warning limit and failure limit respectively.
VSTD = 2 : Adash Standard. Adash is a Czech Republic company specializing in Vibration
Analysis and these limits are based on their 30 years of experience and studying lakhs of
applications. The Adash Warning Limits and Failure limits for Vibration are given in the image
below.
.
VSTD = 3 : Custom Limits. The user can directly set the vibration failure limit based on their
experience, in RMS mm/sec. This limit will be used for the RMS Overall Velocity limit. The
warning level will be 50% of this limit value.
6. Delay - DELY : This is the delay value in seconds. The RMS Overall Vibration Velocity must exceed
the selected limit continuosly for the this delay time for failure to be recognized. Once the failure is
recognized, the relay changes state and the contacts of this relay can be used to stop the equipment
from functioning to prevent major failure and damage. The relay can be reset to normal state, by
using the RESET button on the Vibramon 1 module or by shorting the RESET terminals externally
using a momentary push button. To reset the relay using the RESET/ESC button on the Vibramon 1,
press and hold the RESET/ESC button on the Vibramon 1 for more than 3 seconds.

Keypad operation for Setting of parameters on the Vibramon 1
Process to change a parameter value:
1. Press and hold the UP/INC and the DOWN/NEXT keys, together, for 3 seconds till the display
changes to AL1.
6. To view AL1 press the ENTER key once.
7. To get back to display AL1 press RESET/ESC key once.
8. To scroll through the different parameters in the forward direction, press either the UP/INC key once
or to scroll through in the reverse direction press the DOWN/NEXT key once.
9. To view or change a parameter value, press the ENTER key once. The blinking dot in the display
indicates which digit value can be changed.
10. To change a digit value use the UP/INC key. Press once to increment a digit value by 1. Pressing the
UP/INC key repeatedly will scroll through the digit value from 0 to 9 to 0 in a circular manner.
11. To select the next digit, press the DOWN/NEXT key once. Pressing the DOWN/NEXT key repeatedly
will scroll through all the digits in a circular manner.
12. Once the desired value is displayed, this new value can be set by pressing the ENTER key once. The
ENTER key is acknowledged by lighting up the dot on the rightmost digit.
13. Press RESET/ESC key to return to the parameter menu. Press it one more time to return to normal
operation, to display the RMS Overall Velocity.
Note:
The parameters of the Vibramon 1 should be changed only by authorized personnel who are
familiar with vibration standards and/or aware of the settings required for their application.
Vibramon 1 is to be used only for condition monitoring where the condition gradually worsens
with continous normal use of the equipment. It should not be used as a safety device to detect
sudden, catastrophic vibrations due to overload or shock. We will not be responsible for misuse
of Vibramon 1 by improper setting or improper application.
