2.4. Use as Agreed The device Patrick is an optical particle monitor that may be used for the monitoring of fluid cleanliness. It works according to the light extinction principle and detects particles and other contaminants in the fluid. The measured values are calculated into purity classes according to ISO4406:99 or SAE AS4059E and then shown on the display. -

Patrick the Particle Counter Operating Instructions You may use Patrick to monitor the contamination level and the purity trend of fluids. There may be differences in the absolute accuracy to particle counters calibrated according to ISO 11171:99, but this difference is smaller than one ordinal number. Changes are display with very high accuracy. By the continuous purity monitoring you can detect changes within a machine very quickly. -

Patrick the Particle Counter Operating Instructions Alarm memory Here you select the reaction of Patrick in case of an alarm. This can either be disabled automatically (set to „Auto off“) or remain active until confirmed by the operator. Smoothing Here you may set an average calculation preventing alarms for a single extreme value. Open the function and set the desired number of values used to calculate the average. -

The display limits (bar chart) are between L = 100 ml/min and H= 400 ml/min. The L (low) starts flashing, if the volume flow rate falls below 100 ml/min. Patrick continues measuring correctly down to the minimal flow rate of 50 ml/min. -
Page 18: Communication Settings
6.1. Serial interface configuration Patrick can be readout and configured via the serial interface. You will need a PC and an installed terminal software to do this. Connect Patrick to an available COM port of the computer. A suited communication cable for the serial connection between sensor and PC/control can be ordered from Hydrotechnik. - Page 19 20020208h SAE6µm, 1 byte in 2002h, sub 02 be mapped PDO mapping for fourth application object to unsigned 33 20020308h SAE14µm, 1 byte in 2002h, sub 03 be mapped © Hydrotechnik GmbH • All rights reserved Page 19 of 21 Rev. 1.8 / 2012-11-29 • L3160-00-76.00EN...
