6.3.3. Service mode
This function can be utilised to acquire an inspection for the permeation rate on the membrane dryer during preventive
service without having to dismantle the device. This inspection can determine whether this should be exchanged when
necessary.
The control system must already be located in setup mode to utilise the service mode (Refer to 6.3). If the service mode is
activated, then the solenoid valve will be closed permanently whereby only the measuring gas flow will flow through the
control system.
This function can be manually deactivated again, otherwise the control system will automatically reset this function to
normal mode after 30 seconds.
Preparation:
Activate setup mode
