COOLER ALARM 0.10A , 5s
▪
COOLER ALARM defines the current (0.1A by default) and the
time (5 seconds by default)
setting for the “ 107_COOLER
FAULT ” event. If the current drawn through the Cooler has
dropped below 0.1 Amp for longer than 5 seconds, BioTector
generates a “ 107_COOLER FAULT ” warning .
▪ When COOLER ALARM current is set to 0.0 Amp, then the
Cooler Fault generation is switched off.
COOLER FAN ALARM 1.00V , 5s
▪ COOLER FAN ALARM defines the Voltage Band (1.0V by
default) and the time (5 seconds by default) settings for the
“ 108_COOLER FAN FAULT ” event. If t he voltage on the Cooler
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 “ 108_COOLER FAN FAULT ” warning .
▪
When COOLER FAN ALARM voltage is set to 0.0 Volt, then the
Cooler Fan Fault generation is switched off.
SIGMATAX FLT DELAY 900s ▪
The SIGMATAX FAULT DELAY function is displayed in systems
programmed to operate with the Sigmatax Sampler.
▪ The SIGMATAX FAULT DELAY defines the time (900 seconds
by default) during which any problems with the “sample ready”
signals, sent from the Sigmatax Sampler to the BioTector, are
ignored.
▪ When there is a problem with the “sample ready” signals, (i.e.
when the IR signal sent from Sigmatax Sampler is low for longer
than the SIGMATAX FAULT DELAY time or when the IR signal
is high for longer than 3600 seconds), BioTector logs a “130_NO
SIGMATAX SIGNAL” fault and stops
.
▪ When Sigmatax Sampler sends an error signal to the BioTector
for lon
ger than 60 seconds, BioTector logs a “131_ SIGMATAX
FAULT” fault and stops .
