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 the 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.
