3.4.4

UV Output Low

The device is equipped with a so called
dosimetry

which

continuously

measures

the

irradiance

during

therapy,  and  adjusts  the  exposure
time  accordingly  in  real  time.  If  this
measuring  system  detects  a  fault
during  treatment,  e.g.  if  some  UV
tubes  or  a  sensor  have  failed  or  a
sensor  has  been  covered,  the  device
aborts

the

treatment

and

a

corresponding message appears on
the display. In this case check if all UV
tubes are actually working (see section
3.3.3). Afterwards carry out a test treatment without patient, which takes more than two minutes.
Should the fault still persist after the test treatment, please contact the MEDlight service!

3.4.5

No Connection

The  touchscreen  is  connected  to  the
controller  of  the  cabin  via  an  internal
network connection. If communication
over  this  network  connection  is
interrupted,  e.g.  because  a  network
cable or the internal network switch is
defective, the message N

O

C

ONNECTION

is displayed. In this case, contact an
authorised MEDlight service technician
immediately to resolve the issue.
