OZONE TEST TIME 18s
 OZONE TEST TIME defines the programmed time (18 seconds
by default), which passes the Ozone Test in Process Test,
Ozone Test menu. The maximum time the ozone generator
remains on during the Ozone Test is 60 seconds.
OZONE GEN ALARM 0.50A , 5s
 OZONE GENERATOR ALARM defines the current (0.5A by
default) and the time (5 seconds by default) setting for the
“102_OZONE GEN FAULT” event. If the current drawn through
the Ozone Generator has dropped below 0.5 Amp for longer
than 5 seconds, BioTector generates a “102_OZONE GEN
FAULT” warning.
OZONE GEN FAN ALARM 1.00V , 5s
 OZONE GENERATOR FAN ALARM defines the Voltage Band
(1.0V by default) and the time (5 seconds by default) settings for
the “103_OZONE FAN FAULT” event. If the voltage on the
Ozone Generator Fan drops below 2.5V minus the Voltage Band
(i.e. 1.5V by default), or if the voltage increases more than 2.5V
plus the Voltage Band (i.e. 3.5V by default), for longer than 5
seconds, BioTector generates a “103_OZONE FAN FAULT”
warning.
 When OZONE GENERATOR FAN ALARM voltage is set to 0.0
Volt, then the Ozone Fan Fault generation is switched off.
SAMPLE STATUS 5s , 95%
 The first parameter in SAMPLE STATUS setting is the sample
detection time (5 seconds by default) BioTector processes the
output of the Sample Sensor. When the parameter is set to 0s
(zero seconds), the sample detection is switched off. The
second parameter (95% by default) is the % sample quality
threshold, which is used to activate SAMPLE STATUS output.
 Sample Status output is activated (energized) when BioTector
Sample Sensor detects no sample or when the sample quality is
less than the default 95% threshold value.
 Sample Status output is set/reset as soon as the Sample Sensor
signal is processed. Sample Status holds its state between
reactions and when system is stopped or put into standby mode.
ARCHIVE NO
 In systems built with Sample Sensor, if SAMPLE STATUS
ARCHIVE function is programmed as “YES”, the “116/117/118
LOW/NO SAMPLE 1/2/3” notification events are generated and
logged into the Fault Archive when there is no or low sample
liquid in the corresponding streams from stream 1 to stream 3.
AUTO RESET NO
 If SAMPLE STATUS AUTO RESET function is programmed as
“YES”, the corresponding “116/117/118 LOW/NO SAMPLE
1/2/3” notification events are automatically acknowledged in the
Fault Archive depending on the sample status of the relevant
streams from stream 1 to stream 3.
 In multi-stream systems, the Sample Status relay output signal is
a common signal, which is activated/deactivated when the
sample quality is determined by the BioTector Sample Sensor
for any of the streams during analysis.
SAMPLE FAULT 1 1000s
SAMPLE FAULT 2 1000s
SAMPLE FAULT 3 1000s
 SAMPLE FAULT 1-3 defines the stream specific programmable
output time delay (1000 seconds by default), which delays the
activation of the SAMPLE FAULT 1-3 output signals and logging
of the “122/123/124 SAMPLE FAULT 1/2/3” notification events
into the fault archive. The purpose of the time delay is to prevent
unnecessary generation of the sample fault signals if the sample
fault only occurs for a very short time.
AUTO RESET NO
 SAMPLE FAULT AUTORESET determines whether the
“122/123/124 SAMPLE FAULT 1/2/3” notification events are
automatically acknowledged by the system (with the “YES”
setting) or to be acknowledged manually from the BioTector
keyboard (with the “NO” setting by default).
