By pushing the corresponding red key the password (the same of
start) is requested. Once confirmed the password the function is enabled.
When it is enabled, the corresponding red LED lights up and, for single fan
cabinets, the LAF and exhaust speeds are about 30% lower than their
nominal speeds; for double fan cabinets, the only exhaust speed is about
30% lower than their nominal speed. The light and the gas electrovalve
cannot be switched on. If they are on, they switch off automatically. The
following two messages appear alternatively:
>>>ATTENTION<<<
DANGER
and:
REDUCED AIRFLOW
>>>DO NOT WORK<<<
The “SPEED REDUCTION” function can be enabled only with the main
switch in position “I”. Only the power supply (3) can be operating.
13 U.V. TIMER
This concerns the yellow key for the timed management of the U.V. lamp
(with timer). When the front sash window is completely down, by pushing the
relevant key, you are requested to set the time. The timer resolution is 1
minute
and
the
maximum
time
is
180
minutes
(3
hours).
The display will show the latest pre-set value, which can be changed using
the “arrow” keys; when the time has been set, press the “SET” key to
confirm. At this point the yellow LED lights up, the U.V. lamp is activated and
the countdown starts. During the cycle the following message appears:
U.V. TIMER
U.V. Timer (min) xxxx
where “xxxx” is the time in minutes before the automatic stopping of the U.V.
lamp. When the time reaches zero, the U.V. lamp is disabled and a brief
audible warning signal is activated. To cut off the cycle press the “U.V.
TIMER” key again.
If during the cycle there is a blackout, the timer is set again, the U.V. lamp is
activated again and the countdown starts again. The U.V. lamp is activated
only when the lighting is off. If the lighting is activated when the U.V. TIMER
is on, the U.V. lamp switches off. Also the starting up of the cabinet cuts off
the cycle and switches off the U.V. lamp.
14 U.V.
Yellow key to switch on UV lamp with non programmable timer.
This supplies the U.V. lamp in “manual” mode; when enabled, the display
shows "U.V. on". The U.V. lamp switches on only if the cabinet is off, the
lighting of the cabinet is off and the front sash windfow is completely closed.
After 180 minutes the U.V. lamp switches off automatically.
