Ageing Of The Sensor; Replacing The Sensor - Vetus PD1000 Instructions D'installation Et Mode D'emploi

4 Ageing of the sensor

The sensor ages when it is used for measuring. The extent of the ageing is monitored
by the gas detector. After about 2 years continuous use the sensor is aged and the gas
detector will give a warning.
The LED of the corresponding sensor on the panel will flash red and the red LED on
the particular sensor will also come on. The buzzer will also give the attention signal. A
sensor that has aged must be replaced.

4.1 Replacing the sensor

Fit and connect a new sensor. The LED for the particular panel on the panel will continue
to flash red.
After replacing the sensor this must be made known to the gas detector after which it will
monitor the ageing in the correct way again. Follow the instructions below to do this.
- Switch off the gas detector using the
- Replace the sensor.
- Switch on the gas detector again using the
- Press and hold down the
sensor.

Sensor 2: button +
Keep both buttons pressed in for 10 sec.
A sound will be heard after this to indicate that the ageing clock has been reset to 0.
Release both buttons. The corresponding LED will come on green as soon as the new
sensor has been detected and is functioning correctly.
The sensor will have warmed up after about 1 minute and the gas detector can then
detect the presence of gas reliably.
Only carry out these actions for the sensor that is being replaced and not
for any other existing sensor for which the life cycle is still being monitored,
otherwise the ageing of this will no longer be interpreted correctly. This could
lead to dangerous situations occurring.
