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. M800 transmitter
does not need any pre-configuration.

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 oxy-
gen levels during standby of the plant must be avoid-
ed. 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 measure-
ment value of –1 % air to the transmitter and the trans-
mitter 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
process temperature is reached. The default temperature
set points are different for the different optical sensors.
