3.1 Introduction
Parker Hannifin is responsible for the engineering and delivery of the Sentinel.
3.2 Function
Dehydration and purification of hydraulic fluid.
The Sentinel is not permitted for any other purposes than those stated above.
3.2.1 Running Modes
There are three modes of operation for the Sentinel.
•
Standard mode:
Once started, the machine runs continuously until the moisture level reaches the set
point. When set point is achieved, the Sentinel will automatically shut down.
•
Sentinel mode:
Once started, the machine will power up and sample the oil. If the sample is above the
high moisture level set point, the machine remains on until the lower moisture level set point is reached.
The Sentinel will remain off until the high level set point is reached again.
•
Batch mode:
Once started, the machine runs one batch to the moisture level set point before
discharging. New batches are pulled in until the the inlet moisture is below the set point.
