SAMPLE STATUS
SAMPLE FAULT 1
AUTO RESET
TEMPERATURE ALARM
5s , 75%  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 (75% 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 75% threshold value (i.e. when there is
significant quantity of air bubbles in the stream/manual grab
sample lines).
 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.
1000s  SAMPLE FAULT 1 defines the programmable output time delay
(1000 seconds by default), which delays the activation of the
SAMPLE FAULT 1 output signal and logging of the "122
SAMPLE FAULT 1" notification event into the fault archive. The
purpose of the time delay is to prevent unnecessary generation
of the sample fault signal if the sample fault only occurs for a
very short time.
NO  SAMPLE FAULT AUTORESET determines whether the "122
SAMPLE FAULT 1" notification event is automatically
acknowledged by the system (with the "YES" setting) or to be
acknowledged manually from the BioTector keyboard (with the
"NO" setting by default).

45.0C  TEMPERATURE ALARM represents the BioTector ambient
temperature alarm level (45°C by default).
 If BioTector temperature is higher that the set level for more than
120 seconds, a "53_TEMPERATURE ALARM" warning is
logged into the fault archive.
