Inlet & Outlet Connections
Flow through the unit can be in either direction. The connections provided are 1/8”BSPP threads to
ISO 228/1 with a 60° internal cone to BS 5200, suitable for connecting hydraulic hoses with female
swivel ends.
When attaching hose connections, it’s best practice to remove the front cover of the enclosure and
support the threaded fitting with a spanner where it connects to the particle counter to prevent over
tightening the fitting in the particle counter or put excessive force on the mounting plate.
Electrical Connections
Power is provided through the cable glans on the left (1) and should be 24V, connected to the 2-pin
terminal block.
The cable gland on the right (2) is for connection of an RH moisture sensor. The 4-pin terminal blocks
0V and 24V connections provide power to the sensor, where the 4-20mA outputs of the sensor are
connected to the RH and TEMP terminals to display %RH and temperature on the display.

Operating the Unit
On/Off Switch
Units have a single push
button switch which
illuminates when switched
on, powering up the display
and RH sensor if connected.
Touch Screen Layout
The main window of the touch screen displays all information provided by the particle counter and
any other sensor that may be installed, including the input voltage. The ISO code can change from
white to green or red depending on the alarm limits set.
In the top right corner of the screen is a settings icon, clicking this will open the settings page.

At the bottom left of the settings page the software version is displayed.
ISO Alarm Limits
Alarm limits for low (clean) or high (dirty) can be set. Low refers to oil achieving required cleanliness
codes in all size categories. High refers to oil exceeding any one of the codes for particulate
contamination. When the oil is clean the ISO code on the main screen will turn green, when dirty it
will become red, between the two values the text is white.

Datalogging
The unit contains two internal dataloggers, one for the graph and one for the tests. Whenever the
unit is switched off the graph will be reset, but this can also be done from the screen without having
to switch off the unit. The main data log tied to the sensors will hold 500 lines of data (500 polls of
the sensors) which equates to 16.6 hours of testing.
To create a new log file the button needs to be held down for a couple of seconds, until a
confirmation message is displayed.

Time Zone Adjustment
The display screen is pre-set with the date and date to GMT +0 (UK time) this can be adjusted
according to your time zone if required.
RH Sensor Settings
If an RH sensor is connected to the unit this will need to be activated in the “RH Sensor Settings”
page. Here the temperature scaling can be adjusted to suit the sensor being used.

Troubleshooting
General Operational Errors
Problem
Possible Cause
Solution
Unit will not
switch on.
Power supply issue.
With a multimeter check at the input terminal
block that 24V is being supplied.
Touch screen
does not
power up.
Internal connector issue.
If the switch illuminates but the screen does not
power up check the Molex connector has been
reconnected after assembly.
Screen is
behaving
erratically.
Dirt or moisture on the screen.
Wipe the screen clean to remove traces of dirt,
oil, or moisture. In most cases thick gloves will
not work with the touch screen.
Particle Counting
Problem
Possible Cause
Solution
Contamination
codes dropped
to near zero..
A blockage in
the flow path.
Check there is adequate flow rate going through the unit
(approximately 20-50ml/min).
Check/clean the suction strainer for any contamination.
Erratic count
levels.
Unstable
sample.
Check for the presence of air. Bubble counts should be
maintained below 200 bubbles/ml in each channel.
RH & Water Content
Problem
Possible Cause
Solution
Water content
is above 95%
High moisture levels
in the sample.
Damaged moisture
sensor.
Flush the unit immediately with dry oil to avoid damage
to the moisture sensor. If levels still don’t fall the sensor
could be permanently damaged.
Water content
bouncing from
near 0 to 100%.
Damaged moisture
sensor.
Permanent damaged due to excessive moisture. Sensor
will require replacing.
Temperature
not reading
correctly.
Scaling issue.
Go into the “RH Sensor Setting”menu item and make
sure the scaling has been correctly configured.
