This isthesafety
control boxforthe
R**0acharging machine. It is
able to perform the following cycles:
·R**0amonitoring: Itcontinuosly checkingthe
R**0apollution level with 2 sensors located inthe machine and the
chargingzone.It
willalso power the fan and the
flow sensor. The flow level, as well as the pollution level are
displayedand two set point are setted for safety control.
Up to the *0% of the flammable levelit willjust
power the fan at *0% of the nominal flow and doesnot
display any alarm; between *0 and *5% of the flammability level
thefan is powered at **0% of the speed while an alarm
is display. Just in case of more than *5% of the flammability
levelit
willcut offthe power
to theR**0acharging machine and display an acoustic and
visible alarm.
·Stand
by cycle: Itcan not be switchedoff (a
special keyis given to the
authorised personnel whom is the only person that able to turn off
it duringmaintenancejob). During the production stop,it
willcontinuosly
checkingthe R**0 pollution level and apply the following
stand by cycle: up to *0% of the pollution level the fan is turn
off; between the *0 and *5% the fan start to work at **0% of the
possible flow and the visual alarm is display, in case of pollution
higher than *5% an acoustic and visual alarm will be
display.
·ALARMS.Itcan display the following
alarms:
1.R**0
high pollution level at charging machine;
2.R**0
high pollution level at transfer pump (Optional);
