Setpoints
Selection of setpoint source.
The input / selection fields depend on the current operating mode. Some fields are not
always available.
Local
All setpoints are entered manually via the HMI
Remote
(Hardwired)
All setpoints are set by analog 4W20mA signals
(depending on control mode)
Refer to Chapter System Control Modes
.
Remote (Network)
All setpoints are set via network connection
(depending on control mode)
Refer to Chapter System Control Modes.
Remote
(Wedecontrol)
All setpoints are set via Wedecontrol process control system
(depending on control mode)
Refer to Chapter System Control Modes.
Converter (Ozone prPruction)
Release of the Converter including status indication.
The converter can be turned on / off at any time when in normal operation.
The system can be operated without converter. Here gas flows through the generator, the
energy supply is switched off and thus the manual purge mode is carried out.
OFF
The converter is not released; the ozone generation process is not
in operation.
When the system is started, the system is automatically started up
to the "Start converter (ozone production)" start step. The current
operating status is indicated by the message "Converter waiting for
release signal. Manual purge mode is carried out"
ON
The converter is released, the ozone generation process is in
operation.
When the system is started, the complete start sequence is carried
out automatically up to the step “System in normal operation”
Dew Point Purge Mode (Option)
Release of the Purge Mode including status indication.
If the system is not switched on, the dew point can be kept at the start level for a longer
period of time. This means that a partial flow is continuously discharged via the dew point
purge valve. (start level < -56°C atm.), Purging only takes place if the inlet pressure is above
start level (> operating pressure EOZ).
OFF
When the system is out of operation, no partial flow is discharged
via the dew point purge valve. The dew point is not continuously
maintained at the start level. Recommended for longer periods of
system shutdown!
