11.5 Standard
The display of cleanliness can be chosen according to one of the following standards:
› ISO 4406:17
› SAE AS 4059E
› NAS 1638
› GOST 17216
NAS and GOST are only available from software version 2.00.15.
It has to be considered that for SAE AS 4059E the sizes 38 and 70µm are not analyzed in separate channels.
The setting only applies to the display on the start screen. In the internal memory and on the issue via digital interfaces
(CAN or RS232) all standards are visible.
Which standard is selected, can be seen on the start screen, bottom left.
11.6 Configuration flow
11.6.1 Automatic
In addition to the particle size and number of particles, the OPCom Particle Monitor also calculates a volume flow index to be able to
evaluate the particle concentration.
The calculated flow rate index is not an exact measurement of the volume flow. It is an internal calculation value,
which may be used as an indicator during installation and commissioning of the unit. The device should not be
viewed or used as a flow meter.
11.6.2 Fix
The particle concentration is then calculated, starting from the fixed set flow rate. The value is to be entered in ml/min.
It is important to ensure that the actual and the fixed flow may not differ significantly. Otherwise, the calculated particle
concentration is not correct.
11.7 Communication
There are several possible settings, which can be specified in the menu.
11.7.1 Type
Here you can choose how the digital interface is configured. Only one type can be chosen. The physical connection is always the
same.
The following types are available:
› RS 232
› CANopen
› CAN J1939
› AUTO CANOPEN (factory setting)
› AUTO J1939
CAN J1939 is only available from software version 2.00.15.
