15.F CONTROL OF ALARMS
ALARM FOR MISFUNCTIONING OF MAIN MOTOR-FAN (LAF)
This alarm can be simulated by disconnecting the power cables of the main motor-fan. When the isolator is
switched o
n and the “stand-by” period is over, check that the red light of the relevant alarm and the visual
and sound (buzzer) signals start.
ALARM FOR MISFUNCTIONING OF SECONDARY MOTOR-FAN (EXHAUST)
Also this alarm can be simulated by disconnecting the power cables of the main motor-fan. . When the
isolator
is switched on and the “stand-by” period is over, check that the red light of the relevant alarm and the
visual and sound (buzzer) signals start.
ALARM FOR REDUCTION OF THE EXHAUST DUCT CAPACITY
To verify this alarm, clog the exhaust duct gradually at the end of stand-by period and check that the red light
of the relevant alarm and the visual and sound (buzzer) signals start. Furthermore check that when the
clogged duct is cleared, the alarm stops.
ALARM FOR OPENING OF THE FRONT WINDOW OF THE ISOLATOR
To verify this alarm it is enough you move the front window from its standard work position removing the four
knobs and check that the red light of the relevant alarm and the visual and sound (buzzer) signals start. Re-
position the window in its standard work position and check that the alarm stops.
ALARM FOR REDUCTION OF LAMINAR AIRFLOW VELOCITY IN THE WORK CHAMBER
During the normal working of the isolator, cover the work surface almost completely with a PVC or cardboard
sheet and check that the relevant red light switches on. When the correct operating conditions of the laminar
airflow are restored, the alarm will stop.
OTHER ALARMS
With the help of FASTER’s technicians also the alarms for LAF and protection barrier velocity below the
minimum threshold or over the maximum threshold can be checked
