6.3.3. Service mode
This function can be used to perform a review of the permeation rate at the membrane dryer during preventive service
without the need to dismount the device. This check can be used to determine whether it may have to be exchanged.
The control unit must already be in setup mode to be able to use the service mode (see 6.3). When activating the service
mode, the solenoid valve will be permanently engaged, which means that only the measuring gas flows through the control
unit.
This function can be deactivated manually, otherwise the control unit resets this function automatically after 30 minutes.
