8.3.12 Ozone Destructor Program
PWM DUTY 50%
 PULSE WIDTH MODULATION defines the standard operation of
the Ozone Destructor Heater. The default 50% settings mean
that the Ozone Destructor Heater is on for 50% of the time,
which is typically 5 seconds on and 5 seconds off during normal
operation.
 When the temperature of the BioTector exceeds 40°C for more
than 2 minutes, system automatically applies a PWM DUTY
setting of 10%, which means that the Ozone Destructor Heater
is on for 10% of the time, which is typically 1 second on and 9
seconds off.
 When the temperature of the BioTector is below 15°C for more
than 2 minutes, system automatically applies a PWM DUTY
setting of 100%, which means that the Ozone Destructor Heater
is on all the time. When system automatically changes the
operation of the Ozone Destructor Heater, no system warnings
are generated.
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 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.
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.
PURGE CYCLE FLOW 58 l/h
 When the PURGE CYCLE MODE above is programmed as
AUTO, and if the flow measured during the Flow Test (see
Section 8.3.4.5 Pressure/Flow Test Program for details) is below
the default PURGE CYCLE FLOW setting of 58 l/h, the Ozone
Destructor heater and the 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 , 40
 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 (40 by default) defines the number of analysis cycles
both the Ozone Destructor heater and the 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.
