8.3.12 Ozone Destructor Program
PURGE CYCLE MODE AUTO
 PURGE CYCLE MODE, which is automatically controlled (AUTO
by default), specifies how the purging of the Ozone Destructor is
carried out. In AUTO (Automatic) mode, the Ozone Destructor
heater and the BioTector Cooler are controlled by the PURGE
CYCLE FLOW and AUTO PURGE CYCLE parameters defined
below.
 When PURGE CYCLE MODE is OFF, the Ozone Destructor
heater and the BioTector Cooler operate normally.
 When PURGE CYCLE MODE is programmed as MAN (Manual),
the Ozone Destructor heater and the Cooler operates as
described in MAN PURGE CYCLE below.
PURGE CYCLE FLOW 77 l/h
 When the PURGE CYCLE MODE above is programmed as
AUTO, and if the flow measured during the Flow Test (see
Section 8.3.4.6 Pressure/Flow Test Program for details) is below
the default PURGE CYCLE FLOW setting of 77 l/h, the Ozone
Destructor heater and the BioTector Cooler operates as
described in AUTO PURGE CYCLE below.
 This menu item is only displayed, when the PURGE CYCLE
MODE operation mode is selected as AUTO above.
AUTO PURGE CYCLE 15 , 15
 When the PURGE CYCLE MODE above is programmed as
AUTO above, in AUTOMATIC PURGE CYCLE setting, the first
parameter (15 by default) defines the number of analysis cycles
the Ozone Destructor heater is switched off. The second
parameter (15 by default) defines the number of analysis cycles
both the Ozone Destructor heater and the BioTector Cooler are
switched off.
 The AUTO PURGE CYCLE operation routine is carried out only
once after the Flow Test routine.
 This menu item is only displayed, when the PURGE CYCLE
MODE operation mode is selected as AUTO above.
MAN PURGE CYCLE 2000, 15, 15
 When the PURGE CYCLE MODE above is programmed as
MAN above, in MANUAL PURGE CYCLE setting, the first
parameter (2000 by default) defines the number of analysis
cycles the Ozone Destructor and the BioTector Cooler operates
as normal. The second parameter (15 by default) defines the
number of analysis cycles the Ozone Destructor heater is
switched off. The third parameter (15 by default) defines the
number of analysis cycles both the Ozone Destructor heater and
the Cooler are switched off.
 When MANUAL PURGE CYCLE is selected, above operation
routine is repeated with the relevant number of programmed
analysis cycles.
 This menu item is only displayed, when the PURGE CYCLE
MODE operation mode is selected as MAN above.
