32 Installing the XM-720 Machine Monitor
Bargraph Meters
The XM-720 front panel has two vertical-scale meters, one for each input
channel. Each meter consists of 31 solid-state lamps (light emitting diodes)
arranged one above the other. Scale markings on the window appear at 3%
increments, thus there is one scale mark for each of the thirty lamps.
In the provided configuration files, each meter is configured to continuously
display the overall vibration level. The amplitude of the signal appears as a
continuous bright light next to the one of the thirty scale marks. This
simplified display makes it easy for you to recognize potential problems as the
measured signal amplitude approaches one of the setpoints.
The measurement displayed in the meter, the full scale, and the alarm and trip
(danger) thresholds are configurable using the XM Serial Configuration Utility.
Refer to Chapter 3 for more information about the XM Serial Configuration
Utility.
The XM-720 is shipped with clear self-adhesive caption sheet for customizing
the meter scale. The caption stickers contain the most popular measured units
and ranges. The caption sheet also contains orange and red arrows for labeling
the alert and danger (trip) threshold levels.
Follow these instructions to customize the scaled face plate.
1. Remove the front bezel. To do this, insert a blade-type screwdriver
between the plastic bezel frame and front panel and lift the bezel off.
2. Remove the scaled faceplate. Be careful not to scratch the clear lens.
3. Peel the desired measured units and the orange and red arrows from the
caption sheet and place on the scaled faceplate. Refer to To determine
placement for Alert and Danger Threshold Arrows on page 33 for an
example.
4. Replace the faceplate, lens and bezel.
