Introduction
Group management
1 group represents machinery or a sub component of machinery. This machinery management was
thought to simplify Online4US settings. Online4US-ACM firmware is organized according the
following methods:
Available Groups
Online4US manages 8 groups. The user may choose to use one or more of the 8 Groups at his
convenience. It is not required to follow the chronological order of the Groups.
Figure 1: Home screen. Groups 1 and 3 are used
Sensors and channels assigned to Groups
One sensor represents one measurement channel. One Group hosts up to 4 sensors (or 4
measurement channels) mixing US and VIB.
Figure 2: Sensors and channels are assigned to Group1
Monitoring scheme
The monitoring scheme is common to all sensors of one Group. The measurement acquisition time
and the monitoring periodicity are the same for the sensors assigned to a Group, so that the
channels of a Group are synchronous.

One Digital input and one analog input are assigned to each group.

for the Danger alarm level.

Recommended steps throughout initial Online4US-
ACM settings
As every situation is unique, the following recommendations should not be considered as
the universal way to efficiently start a permanent monitoring. Many parameters influence
them. Historical data, criticality, machine type and age, spare part availability, Mean-Time-
To-Repair are some. Then this generic guideline should be reviewed as a way to quickly find
relevant information inside this user manual.
1. Velocity unit:
If needed, choose the unit for acceleration velocity between mm/s and ips (inches per
second).
2. Channel assignment:
Assign channels to Groups.
3. Acceptance test:
When possible, collect US and VIB dynamic data respecting sensor location and orientation
with a SDT handheld device.
Analyze time and frequency domain results.
4. Shortened heightened surveillance:
Configure the scheduling for each group using an increased periodicity of data collection (one
hour for instance).
This period should be adapted to the time between a defect occurrence and the component
failure.
5. First alarm set:
Define a first alarm set after having at least 20 readings.
6. Data analysis
Visualize trend curve to detect any suspicious evolution.
7. Alarm set adjustment:
Adjust alarm levels and condition indicator combinations after having at least 100 readings.
8. Long term normal monitoring
Adjust the scheduling for each group using a long term periodicity of data collection (every
12 hours for instance).
This period should be adapted to the time between a defect occurrence and the component
failure as the intervals between scheduled maintenance periods.
9. Configuration saving:
Save the configuration on a USB stick

Channel assignment
From the Home screen, press the parameter icon.
①: An intermediate window asks for your
password (default is 159753).
Figure 8: Password typing
If the password is correct, the main setting
screen is displayed
②: Press the Scan icon
Figure 9: Scan for detecting active channels
③: US channels become blue
④: VIB channels orange
Figure 10: active US channels
are blue, VIB orange
The channel numbering is decided by the CPU Module. There is no relationship between
the Sensor Module physical location with respect to CPU Module and the number
assigned by the CPU Module of its 2 sensor channels.
For instance, for a Sensor Module located just to the right of the CPU Module, the
channel numbers could be 3 and 4, and not 1 and 2. See figure 11.
The following topic explains how to perform the matching between a sensor input of a
Sensor Module and its channel numbering.

Alarm settings
Alarm delay
The machine health status of a Group switches to Warning or Danger only when the
number of consecutive measurements exceeding the Warning or Danger alarm threshold
reaches the Alarm delay set point.
The switching of:
•The color code of the group from the Home screen,
•The color code of the measurement detail screen,
•The corresponding digital output status,
Is performed by Online4US only when the Alarm delay set point is reached.
Alarm delay is a feature to reject false alarm due when an unexpected event without relation to
machine damage causes an abnormally increased reading.
Alarm delay acts as a counter with a set point which is a numerical value adjustable from 0 to 99.
The alarm delay behavior is:
•When a reading triggers an alarm condition, the counter is incremented.
•If the next reading doesn’t trigger the alarm condition, the counter is reset.
•When the number of consecutive readings in alarm matches the alarm delay set point, the
alarm is activated, and the machine health status is changed to Danger or Alert.

B is the Alarm delay counter for the Danger Alarm level.
The measurement 1 is:
•Lower than the Warning alarm level.
•Lower than the Danger alarm level.
The value alarm delay counter is 0 as the set point is 3.
Consequently:
•Machine health status of Group 1 is GOOD.
•Digital output #1 (Warning) status is OFF.
•
Digital output #2 (Danger) status is OFF.
The measurement 2 is:
•Lower than the Warning alarm level.
•Lower than the Danger alarm level.
The value alarm delay counter is 0 as the set point is 3.
Consequently:
•Machine health status of Group 1 is GOOD.
•Digital output #1 (Warning) status is OFF.
•
Digital output #2 (Danger) status is OFF.
The following table indicates for each reading:
•The value of the Warning alarm delay counter (column A).
•The value of the Danger alarm delay counter (column B).

Figure 15: Machine health Status and Digital output status
according to the alarm delay counter value
There is no manual Machine Health status reset. The Machine Health Status is
automatically when one reading doesn’t trigger any alarm condition.
Alarm condition
Alarm condition set point is defined per channel.
The alarm definition is the combination of the 4 condition indicators using Boolean connectors AND
and OR. When a reading fulfills the alarm condition, the Alarm delay counter is incremented.
The available condition indicators are:
•RMS, Max RMS, Peak and Crest Factor for US measurements.
•Acceleration RMS, Velocity RMS, Acceleration Peak and Acceleration Crest Factor for VIB
measurements.
The alarm type corresponds to the Absolute mode in UAS.
