How to use and configure the outputs ranges of the modules

[Yvan Turcotte]

The ZPU’s input modules have the possibility to output values monitored by the sensors to be integrated into the customer’s system or to be read with a scope meter.
Two different signals are accessible:

• The raw value
• The trending value

Those signals are accessible in 0-10 V and 4-20 mA without intervention.

The raw output range cannot be modified and corresponds to the sensor input range  of the sensor.
For example :
A PCS-302 have an input range of 300-2300 microns : 

When viewing a sampling or a pole graph, the display range is the same : 300-2300 microns :

The output ranges of the modules (in 0-10 V and 4-20 mA) are also the same :

For accelerometers, the logic is the same : just be sure to use the raw values in ZOOM Configuration because the sensor might have a wider range, but limited by the module to have better definition.  Also, the raw output is based on the processing and reflects whether the signal is processed with simple or double integration.  For example, a VSM797S with ICPM-5,65 module :

For the trending, you can configure the output for almost any sensor, but it is more useful for displacement and accelerometers to refine the display in front of the ZPU and the output of the modules when the signal processing is in peak-peak, peak or RMS.

For example, by default , the PCS-302 has a complete range for the trending output range (Broadband signal display range), corresponding to 0 to 2000 micrometers peak-peak.

For a better presentation on the screen, it might be interesting to set a smaller range like 0-500 micrometers.

Remember that this setting is applied to :

• The bar graph on the screen of the ZPU
• The trending output range in voltage and current
• The range of the trending graph in ZOOM Application
