Touch the information and setup bar on the appropriate Spray Monitor faceplate.
Select Spray Monitor Configuration from the drop-down menu.
Touch the Service button at the top of the Spray Monitor Configuration window.
NOTE: Only Nordson service personnel can access this setting. Contact your Nordson representative if you need to change this setting.
The Smoothing setting is a time setting (in milliseconds), that the OI uses to determine when or how often to sample the actual pressure in order to arrive at an average pressure. The Smoothing setting applies to both the Fire Pressure and the Base Pressure.
Increasing the Smoothing setting may help to reduce pressure variations or electrical noise from the pressure transducer.
NOTE: If the Smoothing is set for too long, it can prevent the OI from obtaining the samples required for a pressure reading, and can generate a Duration Too Short warning (Fire Pressure) or a Cycle Rate Too Fast Alarm (Base Pressure). If the Smoothing setting is greater than one-half the actual spray duration or spray off time, the Duration Too Short warning or the Cycle Rate Too Fast alarm will be issued.
Default Setting: 5 ms (milliseconds)
For example, the default setting of 5 ms gives different results depending on which sampling mode is selected.
All Samples: An actual pressure sample is taken once every five milliseconds until the gun stops spraying.
Single Samples: A single actual pressure sample is taken 5 milliseconds after the gun starts spraying.
Touch the information and setup bar on the appropriate Spray Monitor faceplate.
Select Spray Monitor Configuration from the drop-down menu.
Touch the Service button at the top of the Spray Monitor Configuration window.
CAUTION: The Smoothing value must be less than the sum of the gun open time and the spray duration, and no more than one-half of the actual spray duration.
Drag the slider or touch the – and + buttons to increase or decrease the Smoothing setting.
