4.5.3.2.1 Option 1
Fig. 8: Wiring diagram switching output option 1
Alarm Explanation
Internal transistor
connects pin 7 to pin 2.
The resistance R now
True
prevents a direct
short-circuit between
pin 1 (L+) and pin 2 (L-).
False Pin 7 is not connected
internally (floating).

Alarm Explanation
Internal transistor
connects pin 7 with
True
pin 2. The voltage is
measured against L-.
False Pin 7 is not connected
internally (floating).

4.5.4 Calibration
The measuring instrument is calibrated based on ISO 11943.
The equipment required for calibration is primary calibrated
according to ISO 11171, thus cannot be traceable to
NIST SRM 2806A.
NOTICE! The sign µm (c) indicates particle size calibration
using ISO-MTD test dust.

The calibration certificate of the device is valid for 18 months
from initial calibration. Subsequent certificates are valid for 12
months.
4.5.4.1 Calibration Note
NOTICE! The function is disabled at the factory.
A message will be displayed when the device needs to be re-
calibrated. See image below. The device is still fully opera-
tional and supplies measurement results. Hold the enter key
[ ] for 2 seconds to clear the message.
The message will then appear again after 500/800 and 900
hours. The device is still fully operational and supplies meas-
urement results. Hold the enter key [
clear the message.
After 1000 hours the message will flash every 2 seconds. The
device is still fully operational and supplies measurement res-
ults. It cannot be cleared.

NOTICE! The calibration warning in the display can only
be cleared by Bühler Technologies GmbH Service.
The hours remaining before the first message appears can be
viewed in the device menu under "SENSOR PARAM > OPERAT-
ING HRS" ("HOURSCAL").
5 Operation and Control
NOTICE
The device must not be operated beyond its specifications.
For a detailed description of the configuration and/or sensor
operation, please refer to the full operating instructions on
our website at www.buehler-technologies.com.

5.1 Before Initial Use

Always read and understand the operating instructions be-
fore starting the equipment.
• Always observe the information related to intended use,
operating conditions and technical data.
• Mount the particle monitor as per chapter Installation
and connection.
• Cables and hoses must be outside the area in which oper-
ating personnel moves around (tripping hazard).
