Operation

5.1

Start-up

Each sensor is supplied ready to use. Before using
remove the protecting cap.

Note: No polarization or calibration is necessary.
"Plug and measure" conception.

5.2 Configuration

5.2.1 Sensor detection

Before installing an optical sensor, please refer to the
manual for the transmitter and configure the transmit-
ter for automatic sensor detection. Date and time must
be set correctly in the transmitter, otherwise diagnostic
functions like DLI / ACT will not work properly.
In the case wrong date and time are set, the calibration
and setup might be corrupted

5.2.2 Sampling rate

Optical oxygen sensors do not measure permanently.
Each measurement cycle has a duration of approx.
1 second. To prolong the lifetime of an OptoCap, the
measurement interval can be set to any value between
1 and 60 seconds. Please choose the appropriate set-
ting. Default setting is 10 seconds which is sufficient
for most applications.

5.2.3 LED mode

One contributing factor for the ageing of an OptoCap
is the measurement itself. To prolong the lifetime of
the OptoCap, the measurement can be switched off
if the system is not needed. Especially measurement
during CIP cycles or when the sensor is exposed to
high oxygen levels during standby of the plant must
be avoided. Measurement during CIP cycles can cause
high sensor drift
When the sensor is not measuring, the sensor LED
is off. In this state the sensor sends a constant mea-
surement value of –1 % air to the transmitter and the
transmitter is set to the "Hold mode". To configure the
"Hold mode" please refer to the transmitter manual.
Automatic switch off at high temperature
If the LED mode is set to "Auto" (default setting) the sen-
sor LED will be switched off as soon as a specific pro-
cess temperature is reached. The default temperature
set points are different for the different optical sensors.
